+### 8.19) Hybrid Logical Clock (HLC) Usage
+
+| Rule | Guidance |
+|------|----------|
+| **Use IHybridLogicalClock for ordering** | For distributed ordering and audit-safe sequencing, use `IHybridLogicalClock` from `StellaOps.HybridLogicalClock`. Never rely on wall-clock time alone for ordering in distributed scenarios. |
+
+```csharp
+// BAD - wall-clock ordering in distributed system
+public async Task EnqueueAsync(Job job)
+{
+    job.EnqueuedAt = DateTimeOffset.UtcNow;  // Clock skew risk!
+    await _store.SaveAsync(job);
+}
+
+// GOOD - HLC ordering
+public async Task EnqueueAsync(Job job, CancellationToken ct)
+{
+    job.THlc = _hlc.Tick();  // Monotonic, skew-tolerant
+    job.EnqueuedAtWall = _timeProvider.GetUtcNow();  // Informational only
+    await _store.SaveAsync(job, ct);
+}
+```
+
+| Rule | Guidance |
+|------|----------|
+| **Deterministic event IDs** | Generate event IDs deterministically from content, not randomly. Use `SHA-256(correlationId \|\| tHlc \|\| service \|\| kind)` for timeline events. This ensures replay produces identical IDs. |
+
+```csharp
+// BAD - random ID breaks replay determinism
+var eventId = Guid.NewGuid().ToString();
+
+// GOOD - deterministic ID from content
+var eventId = EventIdGenerator.Generate(correlationId, tHlc, service, kind);
+// Returns: SHA-256(inputs)[0:32] as hex
+```
+
+| Rule | Guidance |
+|------|----------|
+| **HLC state persistence** | Persist HLC state on graceful shutdown via `IHlcStateStore`. On startup, call `InitializeFromStateAsync()` to restore monotonicity. This prevents HLC regression after restarts. |
+
+```csharp
+// Service startup
+public async Task StartAsync(CancellationToken ct)
+{
+    await _hlc.InitializeFromStateAsync(ct);
+    // HLC will now be >= last persisted value
+}
+
+// Service shutdown
+public async Task StopAsync(CancellationToken ct)
+{
+    await _hlc.PersistStateAsync(ct);
+}
+```
+
+| Rule | Guidance |
+|------|----------|
+| **HLC in event envelopes** | Timeline events must include both `tHlc` (ordering) and `tsWall` (debugging). Use `HlcTimestamp.ToSortableString()` for string representation. Never parse HLC from user input without validation. |
+
+| Rule | Guidance |
+|------|----------|
+| **Clock skew handling** | Configure reasonable `MaxClockSkew` tolerance (default: 5 seconds). Events with excessive skew throw `HlcClockSkewException`. Monitor `hlc_clock_skew_rejections_total` metric. |
+
+**Reference:** See `docs/modules/eventing/event-envelope-schema.md` for the canonical event envelope specification.

+# Sprint 20260105_002_004_BE - HLC: Cross-Module Integration & Testing
+
+## Topic & Scope
+
+Comprehensive integration testing and cross-module wiring for the HLC-based audit-safe job queue ordering implementation. Ensures end-to-end determinism from job enqueue through verdict replay.
+
+- **Working directory:** `src/__Tests/Integration/`, cross-module
+- **Evidence:** Integration test suite, E2E tests, performance benchmarks, documentation
+
+## Problem Statement
+
+Individual HLC components (library, scheduler chain, offline merge) must work together seamlessly:
+- HLC timestamps must flow through Scheduler -> Timeline -> Ledgers
+- Chain links must be verifiable across module boundaries
+- Batch snapshots must integrate with Attestor for DSSE signing
+- Replay must produce identical results with HLC-ordered inputs
+
+## Dependencies & Concurrency
+
+- **Depends on:** All previous sprints (002_001, 002_002, 002_003)
+- **Blocks:** Production rollout
+- **Parallel safe:** Test development can proceed once interfaces are defined
+
+## Documentation Prerequisites
+
+- All previous sprint documentation
+- docs/modules/attestor/proof-chain-specification.md
+- docs/modules/replay/architecture.md
+- src/__Tests/AGENTS.md
+
+## Technical Design
+
+### Cross-Module HLC Flow

+## Documentation Updates
+
+### Files to Update
+
+| File | Changes |
+|------|---------|
+| `docs/ARCHITECTURE_REFERENCE.md` | Add HLC section |
+| `docs/modules/scheduler/architecture.md` | Document HLC ordering |
+| `docs/airgap/OFFLINE_KIT.md` | Add HLC merge protocol |
+| `docs/observability/observability.md` | Add HLC metrics |
+| `docs/operations/runbooks/` | Create `hlc-troubleshooting.md` |
+| `CLAUDE.md` | Add HLC guidelines to Section 8 |
+
+### CLAUDE.md Update (Section 8.19)
+
+```markdown
+### 8.19) HLC Usage for Audit-Safe Ordering
+
+| Rule | Guidance |
+|------|----------|
+| **Use HLC for distributed ordering** | When ordering must be deterministic across distributed nodes or offline scenarios, use `IHybridLogicalClock.Tick()` instead of `TimeProvider.GetUtcNow()`. |
+
+```csharp
+// BAD - wall-clock ordering, susceptible to skew
+var timestamp = _timeProvider.GetUtcNow();
+var job = new Job { CreatedAt = timestamp };
+
+// GOOD - HLC ordering, skew-resistant
+var hlcTimestamp = _hlc.Tick();
+var job = new Job { THlc = hlcTimestamp };
+```
+```
+
+## Decisions & Risks
+
+| Decision | Rationale |
+|----------|-----------|
+| Separate integration test project | Isolation from unit tests; different dependencies |
+| Testcontainers for Postgres | Realistic integration without mocking |
+| Benchmark suite in main repo | Track performance over time; CI integration |
+| Grafana dashboard as code | Version-controlled observability |
+
+| Risk | Mitigation |
+|------|------------|
+| Integration test flakiness | Retry logic; deterministic test data; container health checks |
+| Performance regression | Benchmark baselines; CI gates on performance |
+| Documentation drift | Doc updates required for PR merge |
+

+# Sprint 20260106_001_004_BE - Determinization: Backend Integration
+
+## Topic & Scope
+
+Integrate the Determinization subsystem with backend modules: Feedser (signal attachment), VexLens (VEX signal emission), Graph (CVE node enhancement), and Findings (observation persistence). This connects the policy infrastructure to data sources.
+
+- **Working directories:**
+  - `src/Feedser/`
+  - `src/VexLens/`
+  - `src/Graph/`
+  - `src/Findings/`
+- **Evidence:** Signal attachers, repository implementations, graph node enhancements, integration tests
+
+## Problem Statement
+
+Current backend state:
+- Feedser collects EPSS/VEX/advisories but doesn't emit `SignalState<T>`
+- VexLens normalizes VEX but doesn't notify on updates
+- Graph has CVE nodes but no `ObservationState` or `UncertaintyScore`
+- Findings tracks verdicts but not determinization state
+
+Advisory requires:
+- Feedser attaches `SignalState<EpssEvidence>` with query status
+- VexLens emits `SignalUpdatedEvent` on VEX changes
+- Graph nodes carry `ObservationState`, `UncertaintyScore`, `GuardRails`
+- Findings persists observation lifecycle with state transitions
+
+## Dependencies & Concurrency
+
+- **Depends on:** SPRINT_20260106_001_003_POLICY (gates and policies)
+- **Blocks:** SPRINT_20260106_001_005_FE (frontend)
+- **Parallel safe with:** Graph module internal changes; coordinate with Feedser/VexLens teams
+
+## Documentation Prerequisites
+
+- docs/modules/policy/determinization-architecture.md
+- SPRINT_20260106_001_003_POLICY (events and subscriptions)
+- src/Feedser/AGENTS.md
+- src/VexLens/AGENTS.md (if exists)
+- src/Graph/AGENTS.md
+- src/Findings/AGENTS.md

+
+## Acceptance Criteria
+
+1. `EpssSignalAttacher` correctly wraps EPSS results in `SignalState<T>`
+2. VEX updates emit `SignalUpdatedEvent` for downstream processing
+3. Graph nodes persist `ObservationState` and `UncertaintyScore`
+4. Findings ledger tracks state transitions with audit trail
+5. `SignalSnapshotBuilder` fetches all signals in parallel
+6. Migration creates proper indexes for common queries
+7. All integration tests pass with Testcontainers
+
+## Decisions & Risks
+
+| Decision | Rationale |
+|----------|-----------|
+| Parallel signal fetch | Reduces latency; signals are independent |
+| Graph node hash ID | Deterministic; avoids UUID collision across systems |
+| JSONB for missing_signals | Flexible schema; supports varying signal sets |
+| Separate Graph and Findings storage | Graph for query patterns; Findings for audit trail |
+
+| Risk | Mitigation |
+|------|------------|
+| Signal provider availability | Graceful degradation to `SignalState.Failed` |
+| Event storm on bulk VEX import | Batch event emission; debounce handler |
+| Schema drift across modules | Shared Evidence models in Determinization library |

+# Sprint 20260106_001_004_LB - Cross-Module Material Changes Orchestrator
+
+## Topic & Scope
+
+Create a unified orchestration service that chains Scanner, BinaryIndex, and Unknowns diff capabilities into a single "material changes" report with compact card-style output for reviewers.
+
+- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.MaterialChanges/`
+- **Evidence:** Orchestrator service, unified report model, API endpoints, tests
+
+## Problem Statement
+
+The product advisory requires:
+> **Reviewer UX:** one compact card per change: *what changed -> why it matters -> next action* (e.g., "libxml2.so patched; symbols touched: xmlParseNode; CVE-link updated").
+
+Current state:
+- `Scanner.SmartDiff`: Material risk changes (CVE-level, 4 rules)
+- `Scanner.Diff`: Component-level SBOM changes (layer-aware)
+- `BinaryIndex.Builders`: Function-level fingerprint diffs
+- `BinaryIndex.SymbolDiff`: Symbol table changes (new in SPRINT_20260106_001_003)
+- `Unknowns`: Unknown tracking with provenance hints
+
+**Gap:** These diff sources are **not orchestrated** into a unified report. Reviewers must query multiple APIs and mentally correlate changes across layers.
+
+## Dependencies & Concurrency
+
+- **Depends on:**
+  - SPRINT_20260106_001_003_BINDEX (symbol table diff)
+  - SPRINT_20260106_001_005_UNKNOWNS (provenance hints)
+- **Blocks:** None
+- **Parallel safe:** New library; coordinates existing services

+
+## Acceptance Criteria
+
+1. **Unified Report:** Single API call returns cards from all diff sources
+2. **Card Format:** Each card has what/why/action structure
+3. **Priority Sorting:** Cards sorted by priority descending
+4. **Source Tracking:** Each card shows which modules contributed
+5. **Filtering:** Cards can be filtered by category, scope, priority
+6. **Test Coverage:** Unit tests for each source, integration test for full flow
+
+## Decisions & Risks
+
+| Decision | Rationale |
+|----------|-----------|
+| New library | Orchestration logic separate from source modules |
+| Content-addressed IDs | Enables caching and deduplication |
+| Priority 0-100 scale | Unified scoring across different sources |
+| Card-based output | Matches advisory's "compact card per change" requirement |
+
+| Risk | Mitigation |
+|------|------------|
+| Performance (many sources) | Parallel source queries; caching |
+| Card explosion | MaxCards limit; priority filtering |
+| Source unavailability | Graceful degradation; partial reports |

+# Sprint 20260106_001_005_FE - Determinization: Frontend UI Components
+
+## Topic & Scope
+
+Create Angular UI components for displaying and managing CVE observation state, uncertainty scores, guardrails status, and review workflows. This includes the "Unknown (auto-tracking)" chip with next review ETA and a determinization dashboard.
+
+- **Working directory:** `src/Web/StellaOps.Web/`
+- **Evidence:** Angular components, services, tests, Storybook stories
+
+## Problem Statement
+
+Current UI state:
+- Vulnerability findings show VEX status but not observation state
+- No visibility into uncertainty/entropy levels
+- No guardrails status indicator
+- No review workflow for uncertain observations
+
+Advisory requires:
+- UI chip: "Unknown (auto-tracking)" with next review ETA
+- Uncertainty tier visualization
+- Guardrails status and monitoring indicators
+- Review queue for pending observations
+- State transition history
+
+## Dependencies & Concurrency
+
+- **Depends on:** SPRINT_20260106_001_004_BE (API endpoints)
+- **Blocks:** None (end of chain)
+- **Parallel safe:** Frontend-only changes
+
+## Documentation Prerequisites
+
+- docs/modules/policy/determinization-architecture.md
+- SPRINT_20260106_001_004_BE (API contracts)
+- src/Web/StellaOps.Web/AGENTS.md (if exists)
+- Existing: Vulnerability findings components
+
+## Technical Design
+
+### Directory Structure

+
+## Acceptance Criteria
+
+1. "Unknown (auto-tracking)" chip displays correctly with review ETA
+2. Uncertainty indicator shows tier and completeness percentage
+3. Guardrails badge shows active guardrail count and details
+4. Decay progress shows freshness and staleness warnings
+5. Review queue lists pending observations with sorting
+6. All components work in dark mode
+7. ARIA attributes present for accessibility
+8. Storybook stories document all component states
+9. Unit tests achieve 80%+ coverage
+
+## Decisions & Risks
+
+| Decision | Rationale |
+|----------|-----------|
+| Standalone components | Tree-shakeable; modern Angular pattern |
+| Material Design | Consistent with existing StellaOps UI |
+| date-fns for formatting | Lighter than moment; tree-shakeable |
+| Virtual scroll for queue | Performance with large observation counts |
+
+| Risk | Mitigation |
+|------|------------|
+| API contract drift | TypeScript interfaces from OpenAPI spec |
+| Performance with many observations | Pagination; virtual scroll; lazy loading |
+| Localization complexity | i18n from day one; extract all strings |
+

+## Hybrid Logical Clock (HLC) Ordering
+
+StellaOps uses Hybrid Logical Clocks for audit-safe job queue ordering:
+
+| Component | Description | Documentation |
+|-----------|-------------|---------------|
+| HLC Library | Core HLC timestamp and clock implementation | `src/__Libraries/StellaOps.HybridLogicalClock/` |
+| Scheduler Queue Chain | HLC-based enqueue with cryptographic linking | `docs/modules/scheduler/architecture.md` |
+| Air-Gap Sync | Offline job merge using HLC total ordering | `docs/operations/airgap-operations-runbook.md` |
+| Migration Guide | Enabling HLC ordering in existing deployments | `docs/modules/scheduler/hlc-migration-guide.md` |
+| Troubleshooting | HLC-specific issue resolution | `docs/operations/runbooks/hlc-troubleshooting.md` |
+
+Key concepts:
+- **HLC Timestamp**: Tuple of `(PhysicalTime, LogicalCounter, NodeId)` for total ordering
+- **Chain Linking**: Each job links to its predecessor via cryptographic hash
+- **Batch Snapshots**: Periodic DSSE-signed proofs of chain state
+- **Deterministic Merge**: Offline nodes can merge jobs in correct HLC order
+
+Metrics and observability:
+- Grafana dashboard: `devops/observability/grafana/hlc-queue-metrics.json`
+- Alerting rules: `devops/observability/alerting/hlc-alerts.yaml`

 | Date | Change |
 |------|--------|
+| 2026-01-07 | **Pass 10**: Deep module-by-module audit. **Concelier consolidation**: Merged `federation-setup.md` into `federation-operations.md` (eliminated duplicate federation setup/operations content, added bundle format, cursor format, multi-site topologies, DSSE signature format, monitoring metrics, security considerations sections). Deleted `federation-setup.md`. **Verified module patterns**: advisory-ai (architecture→architecture-detail hierarchy correct), authority (AUTHORITY.md=operational config, architecture.md=component spec - different purposes), concelier guides (aggregation.md=LNM implementation, aggregation-only-contract.md=formal AOC spec), notify (architecture+architecture-detail=hierarchical), policy (determinization-api.md=API ref, determinization-architecture.md=design doc), telemetry (guides/observability.md=AOC-specific, operations/observability.md=collector/storage). Scanner has 104 files well-organized by design/, operations/, guides/, fixtures/ subdirectories. |
+| 2026-01-07 | **Pass 9**: Deep consolidation analysis of major themes. **Crypto cluster consolidation**: Merged `docs/security/crypto-simulation-services.md` into `docs/security/crypto-profile-configuration.md` (eliminated duplication, preserved all unique content including algorithm coverage list, curl examples, `run-sim-smoke.ps1` reference). Deleted redundant file. **Verified well-organized structures**: API/Contracts (distinct purposes - contracts for formal specs, api for reference), technical/architecture (proper index + detailed views), operations runbooks (complementary runbook + troubleshooting patterns), module cross-cutting (architecture + architecture-overview correctly separate index vs content). **Kept compatibility shims**: `07_HIGH_LEVEL_ARCHITECTURE.md` retained as alias (100+ references across AGENTS.md files). **RootPack RU files**: Confirmed `rootpack_ru_validation.md`, `rootpack_ru_package.md`, `rootpack_ru_crypto_fork.md` serve distinct purposes (validation runbook, packaging guide, fork notes) - no consolidation needed. |
+| 2026-01-07 | **Pass 8**: Deep content audit across all major themes. Launched 5 parallel analysis agents covering docs/technical/, docs/security/, docs/operations/, docs/api/+docs/contracts/, and docs/modules/. **Critical fixes**: Fixed 29 files with incorrect `deploy/` paths (changed to `devops/`); fixed 6 files with `scripts/crypto/` paths (changed to `ops/crypto/`). **Placeholder cleanup**: Deleted `docs/security/auth-scopes.md` and `docs/security/redaction-and-privacy.md` (stub files with no content). **Missing READMEs**: Created 9 module README files for: devportal, facet, feedser, packs-registry, provenance, reach-graph, replay, risk-engine, timeline-indexer. **Identified issues for future passes**: API endpoint inconsistencies between docs/api/ and docs/contracts/ (different path formats); duplicate crypto documentation (13 overlapping files); scope definitions in 3 locations (should canonicalize to authority-scopes.md); missing mirror-bundle.schema.json. |
+| 2026-01-07 | **Pass 7**: Final theme consolidation. Thorough analysis confirmed 5 directory pairs should remain separate (distinct purposes/audiences). Executed 4 consolidations: docs/cicd/ (9 files) → docs/technical/cicd/; docs/modules/ci/ (4 files) merged into docs/technical/cicd/ (CI recipes); docs/modules/devops/ (15 files) → docs/operations/devops/ (not a code module); docs/onboarding/ (10 files) → docs/dev/onboarding/ (developer onboarding subsection). Removed duplicate schemas from docs/schemas/ (already in sbom-service/schemas/ and policy/schemas/). Top-level directories reduced from 18 to 15. Module directories reduced from 58 to 55 (removed ci/, devops/, removed duplicates). Fixed 15+ broken references. Verified docs/modules/ alignment with src/ - found Integrations and SmRemote modules lack documentation (stub candidates). |
+| 2026-01-07 | **Pass 6**: Theme-based consolidation and cleanup. Directory consolidations: docs/governance/ (1 file) to operations/governance/; docs/adr/ (4 files) to technical/adr/; docs/contributing/ (3 files) to dev/contributing/; docs/schemas/ (3 files) to modules/sbom-service/schemas/ and modules/policy/schemas/; docs/scripts/sbom-vex/ (9 files) to modules/attestor/samples/sbom-vex/; docs/modules/snapshot/ (3 files) to technical/concepts/snapshot/ (cross-cutting concept); docs/modules/triage/ (3 files) to modules/vuln-explorer/concepts/triage/ (triage implemented in VulnExplorer); docs/modules/testing/ (1 file) to technical/testing/ (cross-cutting testing docs). Removed duplicate template directory: docs/dev/templates/excitor-connector/ (typo, kept excititor-connector/). Verified prov-cache/ and facet/ document real implementations (src/__Libraries/StellaOps.Provcache, src/__Libraries/StellaOps.Facet). Top-level directories reduced from 22 to 18. Fixed 5 broken references to docs/adr/. |
 | 2026-01-06 | **Pass 5**: Reduced top-level directories from 41 to 22, and top-level markdown files from 48 to 25. Directory consolidations: docs/accessibility/ to modules/ui/guides/accessibility/; docs/advisories/ to modules/concelier/guides/; docs/events/ to modules/signals/events/; docs/handoff/ to operations/handoff/; docs/roadmap/ to product/roadmap/; docs/schemas/ to modules/attestor/schemas/; docs/sdks/ to dev/sdks/; docs/specs/ to modules/symbols/specs/; docs/task-packs/ to modules/packs-registry/guides/; docs/ux/ to modules/ui/guides/ux/; docs/rfcs/ to adr/; docs/architecture/ to technical/architecture/; docs/data/ to modules/replay/schemas/; docs/testing/ (26 files) to technical/testing/; docs/diagrams/ to technical/diagrams/; docs/migration/ to technical/migration/; docs/process/ to operations/process/; docs/samples/ distributed to respective module samples/. Top-level file moves: 07_HIGH_LEVEL_ARCHITECTURE.md to technical/architecture/; claims-index.md to product/; cli-vs-ui-parity.md to modules/cli/; LEGAL_*.md to legal/; PERFORMANCE_WORKBOOK.md, DATA_SCHEMAS.md, SYSTEM_REQUIREMENTS_SPEC.md, reproducibility.md to technical/; scanner-core-contracts.md to modules/scanner/; TEST_SUITE_OVERVIEW.md to technical/testing/; VULNERABILITY_EXPLORER_GUIDE.md to modules/vuln-explorer/; PROOF_MOATS_FINAL_SIGNOFF.md, moat.md, VISION.md to product/; QUOTA_*.md to modules/policy/guides/; POLICY_TEMPLATES.md to modules/policy/; AUTHORITY.md to modules/authority/; FAQ_MATRIX.md to onboarding/; RELEASE_ENGINEERING_PLAYBOOK.md to releases/. Fixed ui/guides file to guides-overview.md. Archived QUICKSTART_HYBRID_DEBUG.md. Removed duplicate accessibility.md. |
 | 2026-01-06 | **Pass 4**: Consolidated docs/airgap/ (38 files) into modules/airgap/guides/, runbooks/, gaps/, schemas/, samples/; consolidated docs/aoc/ into modules/aoc/guides/; consolidated docs/policy/ (20 files + fixtures/schemas) into modules/policy/guides/, fixtures/, schemas/; consolidated docs/replay/ into modules/replay/guides/; consolidated docs/uncertainty/ into modules/unknowns/guides/; consolidated docs/forensics/ into modules/evidence-locker/, provenance/, timeline-indexer/ guides/; consolidated docs/ingestion/ into modules/concelier/guides/; consolidated docs/interop/ into modules/attestor/guides/; consolidated docs/observability/ (14 files + dashboards) into modules/telemetry/guides/ and dashboards/; consolidated docs/runtime/ into modules/scanner/guides/; consolidated docs/slo/ into modules/orchestrator/guides/; created modules/devportal/guides/; moved docs/evaluate/ to product/; moved docs/metrics/ to modules/telemetry/guides/ |
 | 2026-01-06 | **Pass 3**: Consolidated docs/router/ into modules/router/ (archived 25 sprints to docs-archived/implplan/router/, moved transports/ and guides/); consolidated docs/reachability/ (23 files) into modules/reach-graph/guides/ and schemas/; consolidated docs/risk/ into modules/risk-engine/guides/ and samples/; consolidated docs/attestor/ and docs/provenance/ into respective modules; consolidated docs/vuln/ into modules/vuln-explorer/guides/; consolidated docs/sbom/ and docs/evidence-locker/ into respective modules; consolidated docs/marketing/ and docs/market/ into docs/product/ (strategy, competitive analysis); archived docs/artifacts/ to docs-archived/ |

+## Phase 2: Unified Event Timeline (Extension)
+
+> **Status:** PLANNING
+> **Sprint Series:** [SPRINT_20260107_003](./SPRINT_20260107_003_000_INDEX_unified_event_timeline.md)
+> **Advisory:** "Unified HLC Event Timeline" (2026-01-07)
+
+Following the completion of HLC core infrastructure, Phase 2 extends the system to provide a **unified event timeline** across all services, enabling:
+
+- **Cross-service correlation:** Events from Scheduler, Router, AirGap, and other services share a common timeline
+- **Instant replay:** Rebuild operational state at any HLC timestamp
+- **Latency analytics:** Measure causal delays (enqueue -> route -> execute -> signal)
+- **Forensic export:** DSSE-signed event bundles for audit and compliance

-Comprehensive integration testing and cross-module wiring for the HLC-based audit-safe job queue ordering implementation. Ensures end-to-end determinism from job enqueue through verdict replay.
+## Objective
 
-- **Working directory:** `src/__Tests/Integration/`, cross-module
-- **Evidence:** Integration test suite, E2E tests, performance benchmarks, documentation
+Complete integration testing, observability infrastructure, and documentation for the HLC-based audit-safe job queue ordering system.
 
-## Problem Statement
+## Working Directory
 
-Individual HLC components (library, scheduler chain, offline merge) must work together seamlessly:
-- HLC timestamps must flow through Scheduler -> Timeline -> Ledgers
-- Chain links must be verifiable across module boundaries
-- Batch snapshots must integrate with Attestor for DSSE signing
-- Replay must produce identical results with HLC-ordered inputs

 ## Decisions & Risks
 
-| Decision | Rationale |
-|----------|-----------|
-| Separate integration test project | Isolation from unit tests; different dependencies |
-| Testcontainers for Postgres | Realistic integration without mocking |
-| Benchmark suite in main repo | Track performance over time; CI integration |
-| Grafana dashboard as code | Version-controlled observability |
+| Decision/Risk | Notes |
+|---------------|-------|
+| Documentation complete | All docs reviewed and cross-references verified |
+| All tests passing | CI pipeline green for HLC test suite |
 
-| Risk | Mitigation |
-|------|------------|
-| Integration test flakiness | Retry logic; deterministic test data; container health checks |
-| Performance regression | Benchmark baselines; CI gates on performance |
-| Documentation drift | Doc updates required for PR merge |

-# Sprint 20260106_001_002_LB - Determinization: Scoring and Decay Calculations
-
-## Topic & Scope
-
-Implement the scoring and decay calculation services for the Determinization subsystem. This includes `UncertaintyScoreCalculator` (entropy from signal completeness), `DecayedConfidenceCalculator` (half-life decay), configurable signal weights, and prior distributions for missing signals.
-
-- **Working directory:** `src/Policy/__Libraries/StellaOps.Policy.Determinization/`
-- **Evidence:** Calculator implementations, configuration options, unit tests
-
-## Problem Statement
-
-Current confidence calculation:
-- Uses `ConfidenceScore` with weighted factors
-- No explicit "knowledge completeness" entropy calculation
-- `FreshnessCalculator` exists but uses 90-day half-life, not configurable per-observation
-- No prior distributions for missing signals
-
-Advisory requires:
-- Entropy formula: `entropy = 1 - (weighted_present_signals / max_possible_weight)`
-- Decay formula: `decayed = max(floor, exp(-ln(2) * age_days / half_life_days))`
-- Configurable signal weights (default: VEX=0.25, EPSS=0.15, Reach=0.25, Runtime=0.15, Backport=0.10, SBOM=0.10)
-- 14-day half-life default (configurable)
-
-## Dependencies & Concurrency
-
-- **Depends on:** SPRINT_20260106_001_001_LB (core models)
-- **Blocks:** SPRINT_20260106_001_003_POLICY (gates)
-- **Parallel safe:** Library additions; no cross-module conflicts
-
-## Documentation Prerequisites
-
-- docs/modules/policy/determinization-architecture.md
-- SPRINT_20260106_001_001_LB (core models)
-- Existing: `src/Excititor/__Libraries/StellaOps.Excititor.Core/TrustVector/FreshnessCalculator.cs`

-## Acceptance Criteria
-
-1. `UncertaintyScoreCalculator` produces entropy [0.0, 1.0] for any input
-2. `DecayedConfidenceCalculator` correctly applies half-life formula
-3. Decay never drops below configured floor
-4. Missing signals correctly contribute to higher entropy
-5. Signal weights are normalized before calculation
-6. Priors are applied when signals are missing
-7. All services registered in DI correctly
-8. Configuration options validated at startup
-9. Metrics emitted for observability
-
-## Decisions & Risks
-
-| Decision | Rationale |
-|----------|-----------|
-| 14-day default half-life | Per advisory; shorter than existing 90-day gives more urgency |
-| 0.35 floor | Consistent with existing FreshnessCalculator; prevents zero confidence |
-| Normalized weights | Ensures entropy calculation is consistent regardless of weight scale |
-| Conservative priors | Missing data assumes moderate risk, not best/worst case |
-
-| Risk | Mitigation | Status |
-|------|------------|--------|
-| Calculation overhead | Cache results per snapshot; calculators are stateless | OK |
-| Weight misconfiguration | Validation at startup; presets for common scenarios | OK |
-| Clock skew affecting decay | Use TimeProvider abstraction; handle future timestamps gracefully | OK |
-| **Missing .csproj files** | **Created StellaOps.Policy.Determinization.csproj and StellaOps.Policy.Determinization.Tests.csproj** | **RESOLVED** |
-| **Test fixture API mismatches** | **Fixed all evidence record constructors to match Sprint 1 models (added required properties)** | **RESOLVED** |
-| **Property test design unclear** | **SignalSnapshot uses SignalState wrapper pattern with NotQueried(), Queried(value, at), Failed(error, at) factory methods. Property tests implemented using this pattern.** | **RESOLVED** |
-
-## Execution Log
-
-| Date (UTC) | Update | Owner |
-|------------|--------|-------|
-| 2026-01-06 | Sprint created from advisory gap analysis | Planning |
-| 2026-01-06 | Core implementation (DCS-001 to DCS-012) completed successfully - all calculators, weights, priors, options, DI registration implemented | Guild |
-| 2026-01-06 | Tests DCS-013 to DCS-020 created (19 unit tests total: 5 for UncertaintyScoreCalculator, 9 for DecayedConfidenceCalculator, 5 for TrustScoreAggregator) | Guild |
-| 2026-01-06 | Build verification DCS-028 passed - scoring library compiles successfully | Guild |
-| 2026-01-07 | **BLOCKER RESOLVED**: Created missing .csproj files (StellaOps.Policy.Determinization.csproj, StellaOps.Policy.Determinization.Tests.csproj), fixed xUnit version conflicts (v2 → v3), updated all 44 test fixtures to match Sprint 1 model signatures. All 44/44 tests now passing. Tasks DCS-013 to DCS-020 validated and marked DONE. | Guild |
-| 2026-01-07 | **NEW BLOCKER**: Property tests (DCS-021 to DCS-023) require design clarification - SignalSnapshot uses SignalState<T>.Queried() wrapper pattern, not direct evidence records. Test scope unclear: test CalculateEntropy() directly with varying weights, or test through full SignalSnapshot construction? Marked DCS-021 to DCS-027 as BLOCKED. Continuing with other sprint work. | Guild |
-| 2026-01-07 | **BLOCKER RESOLVED**: Created PropertyTests/ folder with EntropyPropertyTests.cs (DCS-021), DecayPropertyTests.cs (DCS-022), DeterminismPropertyTests.cs (DCS-023). SignalState wrapper pattern understood: NotQueried(), Queried(value, at), Failed(error, at). All 64 signal combinations tested for entropy bounds. Decay monotonicity verified. Determinism tests validate repeatability across instances and parallel execution. DCS-021 to DCS-023 marked DONE, DCS-024 to DCS-027 UNBLOCKED. | Guild |
-| 2026-01-07 | **METRICS & DOCS COMPLETE**: DCS-025 stellaops_determinization_uncertainty_entropy histogram with cve/purl tags added to UncertaintyScoreCalculator. DCS-026 stellaops_determinization_decay_multiplier histogram with half_life_days/age_days tags added to DecayedConfidenceCalculator. DCS-027 comprehensive Determinization configuration section (3.1) added to architecture.md with all 12 options, defaults, metric definitions, and SPL integration notes. Library builds successfully. 176/179 tests pass (DCS-024 integration tests fail due to external edits reverting tests to concrete types vs interface registration). | Guild |
-| 2026-01-07 | **SPRINT 3 COMPLETE**: DCS-024 fixed by correcting service registration integration tests to use interfaces (IUncertaintyScoreCalculator, IDecayedConfidenceCalculator) and concrete type (TrustScoreAggregator). All 179/179 tests pass. All 28 tasks (DCS-001 to DCS-028) DONE. Ready to archive. | Guild |

-# Sprint 20260106_001_002_SCANNER - Suppression Proof Model
-
-## Topic & Scope
-
-Implement `SuppressionWitness` - a DSSE-signable proof documenting why a vulnerability is **not affected**, complementing the existing `PathWitness` which documents reachable paths.
-
-- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/`
-- **Evidence:** SuppressionWitness model, builder, signer, tests
-
-## Problem Statement
-
-The product advisory requires **proof objects for both outcomes**:
-
-- If "affected": attach *minimal counterexample path* (entrypoint -> vulnerable symbol) - **EXISTS: PathWitness**
-- If "not affected": attach *suppression proof* (e.g., dead code after linker GC; feature flag off; patched symbol diff) - **GAP**
-
-Current state:
-- `PathWitness` documents reachability (why code IS reachable)
-- VEX status can be "not_affected" but lacks structured proof
-- Gate detection (`DetectedGate`) shows mitigating controls but doesn't form a complete suppression proof
-- No model for "why this vulnerability doesn't apply"
-
-**Gap:** No `SuppressionWitness` model to document and attest why a vulnerability is not exploitable.
-
-## Dependencies & Concurrency
-
-- **Depends on:** None (extends existing Witnesses module)
-- **Blocks:** SPRINT_20260106_001_001_LB (rationale renderer uses SuppressionWitness)
-- **Parallel safe:** Extends existing module; no conflicts
-
-## Documentation Prerequisites
-
-- docs/modules/scanner/architecture.md
-- src/Scanner/AGENTS.md
-- Existing PathWitness implementation at `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/Witnesses/`

-
-## Acceptance Criteria
-
-1. **Completeness:** All 10 suppression types have dedicated builders
-2. **DSSE Signing:** All suppression witnesses are signable with DSSE
-3. **Determinism:** Same inputs produce identical witness IDs (content-addressed)
-4. **Schema:** JSON schema registered at `stellaops.suppression.v1`
-5. **Integration:** ReachabilityStackEvaluator returns SuppressionWitness for not-affected findings
-6. **Test Coverage:** Unit tests for all builder methods, property tests for determinism
-
-## Decisions & Risks
-
-| Decision | Rationale |
-|----------|-----------|
-| 10 suppression types | Covers all common not-affected scenarios per advisory |
-| Content-addressed IDs | Enables caching and deduplication |
-| Confidence scores | Different evidence has different reliability |
-| Optional expiration | Some suppressions are time-bounded (e.g., pending patches) |
-
-| Risk | Mitigation |
-|------|------------|
-| False suppression | Confidence thresholds; manual review for low confidence |
-| Missing suppression type | Extensible enum; can add new types |
-| Complex evidence | Structured sub-records for each type |
-| **RESOLVED: Build successful** | **All dependencies restored. Build completed in 272.1s with no errors. SuppressionWitness implementation verified and ready for continued development.** |

+### PH-028 Blocking Analysis
+
+**Root Cause:** The `StellaOps.Unknowns.WebService` project does not exist. This sprint assumed an existing WebService scaffolding that was never created.
+
+**Evidence:**
+- No `src/Unknowns/StellaOps.Unknowns.WebService/` directory exists
+- No `StellaOps.Unknowns.WebService.csproj` file found in the codebase
+- The Unknowns module only has `__Libraries/` (Core, PostgreSQL) and `__Tests/` directories
+
+**Dependency:** PH-028 now depends on WS-007 (WebService scaffolding completion) instead of PH-027.

+# Sprint Series 20260107_003 - Unified Event Timeline
+
+## Executive Summary
+
+This sprint series extends the HLC infrastructure (Sprint Series 002) to provide a **unified event timeline** across all StellaOps services. This enables instant-replay capabilities, cross-service correlation, latency-aware analytics, and forensic event export for audit compliance.
+
+> **Prerequisite:** [SPRINT_20260105_002](./SPRINT_20260105_002_000_INDEX_hlc_audit_safe_ordering.md) (HLC Audit-Safe Ordering) must be complete
+> **Advisory:** "Unified HLC Event Timeline" (2026-01-07)
+> **Gap Analysis:** [See parent INDEX](./SPRINT_20260105_002_000_INDEX_hlc_audit_safe_ordering.md#phase-2-unified-event-timeline-extension)
+
+## Problem Statement
+
+With HLC-based job ordering in place, we now have:
+- Per-service HLC timestamps (Scheduler, AirGap)
+- Chain-linked audit logs per module
+- Offline merge capability
+
+However, operators still cannot:
+- Correlate events **across services** with a unified timeline
+- **Replay** operational state at a specific HLC timestamp
+- Measure **causal latency** (enqueue -> route -> execute -> signal)
+- **Export** forensic event bundles with DSSE attestation
+
+## Solution Architecture

+
+## Key Design Decisions
+
+### DD-001: Event Envelope Schema
+
+The canonical event envelope uses **deterministic** fields only:
+
+```csharp
+/// <summary>
+/// Canonical event envelope for unified timeline.
+/// </summary>
+public sealed record TimelineEvent
+{
+    /// <summary>
+    /// Deterministic event ID: SHA-256(correlation_id || t_hlc || service || kind).
+    /// NOT a random ULID - ensures replay determinism.
+    /// </summary>
+    public required string EventId { get; init; }
+
+    /// <summary>
+    /// HLC timestamp from the existing StellaOps.HybridLogicalClock library.
+    /// Uses HlcTimestamp.ToSortableString() format.
+    /// </summary>
+    public required HlcTimestamp THlc { get; init; }
+
+    /// <summary>
+    /// Wall-clock time (informational only, not used for ordering).
+    /// </summary>
+    public required DateTimeOffset TsWall { get; init; }
+
+    /// <summary>
+    /// Service that emitted the event.
+    /// </summary>
+    public required string Service { get; init; }
+
+    /// <summary>
+    /// W3C Trace Context traceparent for OpenTelemetry correlation.
+    /// </summary>
+    public string? TraceParent { get; init; }
+
+    /// <summary>
+    /// Correlation ID linking events (e.g., scanId, jobId, artifactDigest).
+    /// </summary>
+    public required string CorrelationId { get; init; }
+
+    /// <summary>
+    /// Event kind (ENQUEUE, ROUTE, EXECUTE, EMIT, ACK, ERR, etc.).
+    /// </summary>
+    public required string Kind { get; init; }
+
+    /// <summary>
+    /// RFC 8785 canonicalized JSON payload.
+    /// </summary>
+    public required string Payload { get; init; }
+
+    /// <summary>
+    /// SHA-256 hash of the canonical payload.
+    /// </summary>
+    public required byte[] PayloadDigest { get; init; }
+
+    /// <summary>
+    /// Engine/resolver version for reproducibility (per CLAUDE.md Rule 8.2.1).
+    /// </summary>
+    public required EngineVersionRef EngineVersion { get; init; }
+
+    /// <summary>
+    /// Optional DSSE signature (keyId:signature).
+    /// </summary>
+    public string? DsseSig { get; init; }
+
+    /// <summary>
+    /// Schema version for envelope evolution.
+    /// </summary>
+    public required int SchemaVersion { get; init; }
+}
+
+public sealed record EngineVersionRef(
+    string EngineName,
+    string Version,
+    string SourceDigest);
+```
+
+**Rationale:**
+- `EventId` is deterministic (not ULID) to support replay
+- `THlc` uses existing `HlcTimestamp` type, not string parsing
+- `Payload` requires RFC 8785 canonicalization (per CLAUDE.md Rule 8.7)
+- `EngineVersion` included for reproducibility verification (per CLAUDE.md Rule 8.2.1)
+- `SchemaVersion` enables envelope evolution
+
+### DD-002: No Vector Clocks (Initially)
+
+The original advisory suggested optional vector clocks. **Decision: Defer.**
+
+**Rationale:**
+- HLC provides sufficient ordering for StellaOps use cases
+- Vector clocks add operational complexity
+- Can be added in future sprint if causality conflicts emerge
+
+### DD-003: PostgreSQL Storage with Schema Isolation
+
+Events stored in dedicated `timeline` schema (per StellaOps convention):
+
+```sql
+CREATE SCHEMA IF NOT EXISTS timeline;
+
+CREATE TABLE timeline.events (
+    event_id        TEXT PRIMARY KEY,
+    t_hlc           TEXT NOT NULL,  -- HlcTimestamp.ToSortableString()
+    ts_wall         TIMESTAMPTZ NOT NULL,
+    service         TEXT NOT NULL,
+    trace_parent    TEXT,
+    correlation_id  TEXT NOT NULL,
+    kind            TEXT NOT NULL,
+    payload         JSONB NOT NULL,
+    payload_digest  BYTEA NOT NULL,
+    engine_name     TEXT NOT NULL,
+    engine_version  TEXT NOT NULL,
+    engine_digest   TEXT NOT NULL,
+    dsse_sig        TEXT,
+    schema_version  INTEGER NOT NULL DEFAULT 1,
+    created_at      TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+
+-- Primary query pattern: events by correlation, ordered by HLC
+CREATE INDEX idx_events_corr_hlc ON timeline.events (correlation_id, t_hlc);
+
+-- Service-specific queries
+CREATE INDEX idx_events_svc_hlc ON timeline.events (service, t_hlc);
+
+-- Payload search
+CREATE INDEX idx_events_payload ON timeline.events USING GIN (payload);
+
+-- Partitioning by month for retention management
+-- (implemented via pg_partman in production)
+```
+
+### DD-004: Integration with Existing Replay Infrastructure
+
+Timeline API integrates with existing `StellaOps.Replay.Core`:
+
+- `KnowledgeSnapshot` extended to include timeline event references
+- `ReplayManifestWriter` extended to include HLC timeline bounds
+- Replay verification uses timeline events for ordering
+
+### DD-005: No Valkey/Redis in Air-Gap Deployments
+
+The original advisory mentioned Valkey streams. **Decision: PostgreSQL-only for air-gap.**
+
+**Rationale:**
+- StellaOps is designed for offline/air-gapped operation
+- Valkey may not be available in all deployments
+- PostgreSQL provides sufficient performance for event storage
+- Optional Valkey integration can be added for real-time tailing in online deployments
+
+---
+

+## Risk Register
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| Performance at scale | Medium | Medium | Partitioning, indexes, materialized views |
+| Schema evolution | Low | Medium | SchemaVersion field, migration path |
+| Air-gap complexity | Medium | Low | PostgreSQL-only storage, no external dependencies |
+| UI rendering performance | Low | Low | Virtual scrolling, lazy loading |
+
+---
+
+## Success Criteria
+
+1. **Unified Timeline:** Events from 5+ services queryable by correlation ID
+2. **HLC Ordering:** Events correctly ordered by HLC timestamp
+3. **Replay Support:** Dry-run replay produces deterministic results
+4. **Export:** DSSE-signed event bundles pass verification
+5. **Performance:** Timeline query < 100ms for 10K events
+6. **UI:** Timeline visualization renders 1K events smoothly
+

+# Sprint Series 20260107_004 - SPDX 3.0.1 Profile-Based SBOM Support
+
+## Executive Summary
+
+This sprint series implements full SPDX 3.0.1 support with profile-based SBOM generation and parsing. The current StellaOps implementation only supports SPDX 2.2/2.3, creating a critical gap in the platform's stated capabilities. This series addresses that gap by implementing the JSON-LD Element model, profile conformance, and integration with existing attestation and VEX infrastructure.
+
+> **Advisory:** "SPDX 3.0.1 Profile-Based Model" (2026-01-07)
+> **Gap Analysis:** SPDX 3.0.1 advisory vs. current implementation (2026-01-07)
+> **Priority:** P0 - Critical (documentation accuracy issue)
+
+## Problem Statement
+
+### Current State
+
+| Capability | Claimed | Actual | Gap |
+|------------|---------|--------|-----|
+| SPDX Version Support | 3.0.1 | 2.2/2.3 only | CRITICAL |
+| Profile Conformance | N/A | Not implemented | HIGH |
+| JSON-LD Parsing | N/A | Not implemented | CRITICAL |
+| Build Profile | N/A | Not integrated with Attestor | HIGH |
+| Security Profile | N/A | Not mapped to VEX | MEDIUM |
+
+### Evidence
+
+**SpdxParser.cs:14-15:**
+```csharp
+/// Supports SPDX 2.2 and 2.3 schemas.  // <-- NOT 3.0.1
+```
+
+**spdx-jsonld-3.0.1.schema.json:4:**
+```json
+"$comment": "Placeholder schema for SPDX 3.0.1 JSON-LD..."  // <-- Stub only
+```
+
+### Impact
+
+- Documentation claims SPDX 3.0.1 support that doesn't exist
+- Compliance audits may fail SBOM validation
+- Cannot leverage profile-based flexibility (AI, Build, Security profiles)
+- Integration with modern supply-chain tools limited
+

+## SPDX 3.0.1 Technical Overview
+
+### JSON-LD Structure
+
+SPDX 3.0.1 uses JSON-LD with a fundamentally different structure from 2.x:
+
+```json
+{
+  "@context": "https://spdx.org/rdf/3.0.1/spdx-context.jsonld",
+  "@graph": [
+    {
+      "@type": "SpdxDocument",
+      "spdxId": "urn:spdx:example-1",
+      "creationInfo": { ... },
+      "element": [ ... ],
+      "rootElement": [ ... ]
+    },
+    {
+      "@type": "software_Package",
+      "spdxId": "urn:spdx:pkg-1",
+      "name": "example-package",
+      "software_packageVersion": "1.0.0",
+      ...
+    }
+  ]
+}
+```
+
+### Profile URIs
+
+```
+Core:      https://spdx.org/rdf/3.0.1/terms/Core/ProfileIdentifierType/core
+Software:  https://spdx.org/rdf/3.0.1/terms/Software/ProfileIdentifierType/software

+
+### Element Types
+
+| Category | Element Types |
+|----------|---------------|
+| Core | Element, Relationship, Annotation, ExternalRef, ExternalIdentifier |
+| Software | Package, File, Snippet, SpdxDocument |
+| Security | VulnAssessmentRelationship, VexAffectedVulnAssessmentRelationship |
+| Build | Build |
+| AI | AiPackage |
+| Dataset | DatasetPackage |
+
+### Relationship Types (Subset)
+
+| Type | Description |
+|------|-------------|
+| CONTAINS | Element contains another |
+| DEPENDS_ON | Dependency relationship |
+| BUILD_TOOL_OF | Build tool used |
+| GENERATES | Element generates another |
+| DESCENDANT_OF | Derived from |
+| VARIANT_OF | Variant of another |
+| ANCESTOR_OF | Parent of |
+
+---
+
+## Key Design Decisions
+
+### DD-001: Separate Parser from 2.x
+
+**Decision:** Create new `Spdx3Parser` rather than extending `SpdxParser`.
+
+**Rationale:**
+- Fundamentally different data model (JSON-LD vs flat JSON)
+- Cleaner separation of concerns
+- Easier testing and maintenance
+- 2.x parser remains stable for legacy documents
+
+### DD-002: Profile-Aware Model
+
+**Decision:** Internal model includes profile conformance metadata.
+
+```csharp
+public sealed record Spdx3Document
+{
+    public required ImmutableArray<ProfileIdentifier> ConformsTo { get; init; }
+    public required ImmutableArray<Spdx3Element> Elements { get; init; }
+    // ...
+}
+```
+
+### DD-003: Lazy Context Resolution
+
+**Decision:** Cache and lazily resolve JSON-LD contexts.
+
+**Rationale:**
+- Remote context fetching is slow
+- Air-gap deployments need local contexts
+- Caching improves performance
+
+### DD-004: Bidirectional Conversion
+
+**Decision:** Support both parsing and generation of SPDX 3.0.1.
+
+**Rationale:**
+- Scanner needs to generate SBOMs
+- AirGap importer needs to parse SBOMs
+- Export needs to produce compliant documents
+
+### DD-005: Profile Validation Optional
+
+**Decision:** Profile validation is opt-in, not mandatory.
+
+**Rationale:**
+- Some use cases only need parsing, not validation
+- Strict validation can be slow
+- Flexibility for different deployment contexts
+
+---
+
+## Task Summary
+
+### Sprint 004_001: Core Parser (18 tasks)
+- JSON-LD context handling
+- Element model classes
+- Relationship parsing
+- CreationInfo parsing
+- ExternalRef/ExternalIdentifier parsing
+- Spdx3Document aggregation
+- Profile conformance detection
+- Unit tests with sample documents
+- Benchmarks
+
+### Sprint 004_002: SBOM Generation (15 tasks)
+- Software profile generation
+- Lite profile generation
+- Package element creation
+- File element creation (optional)
+- Relationship generation
+- Integration with existing Scanner
+- Configuration options
+- Output format selection (3.0.1 vs 2.3)
+
+### Sprint 004_003: Build Profile (12 tasks)
+- Build element generation
+- Attestor integration
+- DSSE signature mapping
+- Build tool references
+- Configuration sources
+- Integration tests
+
+### Sprint 004_004: Security Profile (14 tasks)
+- VulnAssessmentRelationship mapping
+- VEX statement conversion
+- VexLens integration
+- Severity/CVSS mapping
+- Integration tests
+
+---
+
+## Migration Strategy
+
+### Phase 1: Parallel Support
+- Both 2.x and 3.0.1 parsers active
+- Generation defaults to 2.3 for compatibility
+- 3.0.1 generation opt-in via configuration
+
+### Phase 2: 3.0.1 Default
+- Generation defaults to 3.0.1
+- 2.x generation available via configuration
+- Deprecation warnings for 2.x-only features
+
+### Phase 3: 2.x Maintenance Mode
+- 2.x parser maintained for legacy import
+- No new features for 2.x
+- Documentation updated
+
+---
+
+## Success Criteria
+
+1. **Parsing:** Successfully parse SPDX 3.0.1 documents from major tools (Syft, Trivy, SBOM Tool)
+2. **Generation:** Produce valid SPDX 3.0.1 documents that pass `spdx-tools` validation
+3. **Profiles:** Support Core, Software, Lite, Build, and Security profiles
+4. **Performance:** Parsing performance within 2x of 2.x parser
+5. **Integration:** Build profile integrates with Attestor; Security profile with VexLens
+
+---
+
+## Metrics to Monitor

+# Parsing
+spdx3_parse_duration_seconds{profile}
+spdx3_parse_elements_total{element_type}
+spdx3_parse_errors_total{error_type}

+
+## Documentation Deliverables
+
+- [ ] `docs/modules/sbom-service/spdx3-profile-support.md` - Profile support guide
+- [ ] `docs/modules/sbom-service/spdx3-migration.md` - Migration from 2.x
+- [ ] `docs/modules/scanner/sbom-generation.md` - Updated generation docs
+- [ ] `docs/modules/attestor/build-profile.md` - Build profile integration
+- [ ] `CLAUDE.md` - Fix SPDX version accuracy (remove 3.0.1 claim until implemented)

+
+## Risk Register
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| JSON-LD complexity | Medium | Medium | Use established library (json-ld.net) |
+| Spec interpretation | Medium | Low | Reference spdx-tools implementation |
+| Performance regression | Low | Medium | Benchmark early, optimize hot paths |
+| Breaking changes in 3.0.2+ | Low | Medium | Abstract version-specific logic |

+# Sprint SPRINT_20260107_005_000 INDEX - CycloneDX 1.7 Native Evidence and Pedigree Fields
+
+> **Status:** TODO
+> **Priority:** P1
+> **Created:** 2026-01-07
+> **Epic:** Dual-Spec SBOM Excellence
+
+## Executive Summary
+
+This sprint series implements native CycloneDX 1.7 `evidence` and `pedigree` fields, replacing custom property-based storage with spec-compliant structures. Combined with the SPDX 3.0.1 profile sprint (SPRINT_20260107_004), this enables StellaOps to produce dual-spec attestations from the same ground truth.
+
+## Background
+
+### Current State
+
+Evidence is currently stored as custom CycloneDX properties:
+```json
+{
+  "properties": [
+    { "name": "stellaops:evidence[0]", "value": "crypto:aes-256@/src/crypto.c" },
+    { "name": "stellaops:evidence[1]", "value": "license:MIT@/LICENSE" }
+  ]
+}
+```
+
+### Target State (CycloneDX 1.7)
+
+Use native evidence and pedigree fields:
+```json
+{
+  "evidence": {
+    "identity": {
+      "field": "purl",
+      "confidence": 0.95,
+      "methods": [{ "technique": "binary-analysis", "confidence": 0.90 }]

+> **Status:** TODO
+> **Last Updated:** 2026-01-07
+
+## Objective
+
+Implement native CycloneDX 1.7 evidence field population in the Scanner SBOM generation pipeline, replacing custom `stellaops:evidence[n]` properties with spec-compliant `component.evidence.*` structures.
+
+## Working Directory

+| CycloneDX | `CycloneDX.Models` | Evidence model classes |
+| Scanner Core | `StellaOps.Scanner.Core` | Component evidence data |
+
+---
+
+## Current Implementation
+
+Evidence is stored as custom properties in `CycloneDxComposer.cs`:
+
+```csharp
+// CURRENT: Custom property storage (lines 400-414)
+for (var index = 0; index < component.Evidence.Length; index++)
+{
+    var evidence = component.Evidence[index];
+    properties.Add(new Property
+    {
+        Name = $"stellaops:evidence[{index}]",
+        Value = $"{evidence.Kind}:{evidence.Value}@{evidence.Source}",
+    });
+}
+```
+
+## Target Implementation
+
+Use native CycloneDX 1.7 evidence fields:
+
+```csharp
+// TARGET: Native evidence field population
+var cdxComponent = new Component
+{
+    Evidence = new Evidence
+    {
+        Identity = BuildIdentityEvidence(component),
+        Occurrences = BuildOccurrences(component),
+        Licenses = BuildLicenseEvidence(component),
+        Copyright = BuildCopyrightEvidence(component),

+# Sprint SPRINT_20260107_006_000 INDEX - Evidence-First Chat-Native UX
+
+> **Status:** TODO
+> **Priority:** P1
+> **Created:** 2026-01-07
+> **Epic:** Chat-Native Evidence-First Platform
+
+## Executive Summary
+
+This sprint series implements the "evidence-first, chat-native" UX vision, adding tabbed evidence panels, runtime/diff visualization, conversational AdvisoryAI, OpsMemory decision ledger, and the Reproduce button. This creates a moat where every claim links to signed proofs and decisions are auditable/replayable.
+
+## Background
+
+### Advisory Vision
+
+> "Evidence-first UX: every claim is deep-linkable to signed objects; competitors mostly show dashboards—Stella shows proofs."
+
+### Current State
+
+StellaOps has a strong foundation:
+- ✅ Left-lane navigation with provenance breadcrumb
+- ✅ Inline policy controls with signed decisions
+- ✅ Reachability visualization (3 modes)
+- ✅ Timeline module with HLC ordering
+- ✅ eBPF function-level traces
+- ✅ AdvisoryAI with grounded responses
+
+### Gaps
+
+- ❌ Tabbed evidence panel (Provenance/Reachability/Diff/Runtime/Policy)
+- ❌ Diff viewer for backport verification
+- ❌ Runtime tab showing live function traces
+- ❌ Conversational AdvisoryAI chat interface
+- ❌ OpsMemory decision ledger
+- ❌ Reproduce button implementation
+

+
+**Total:** 67 tasks, ~19 days effort
+
+## Module Mapping
+
+| Advisory Module | StellaOps Implementation |
+|-----------------|--------------------------|
+| TriageView | Existing: `FindingsDetailPageComponent` |
+| EvidencePanel | NEW: `TabbedEvidencePanelComponent` |
+| PolicyInline | Existing: `DecisionDrawerEnhancedComponent` |
+| AuditTrail | Existing: Timeline module + NEW: Reproduce button |
+| AdvisoryAI | Existing + NEW: Chat interface |
+| OpsMemory | NEW: `StellaOps.OpsMemory` module |
+| AutomationHub | Phase 2 (deferred) |
+
+## Data Contracts Alignment
+
+| Contract | Advisory | StellaOps |
+|----------|----------|-----------|
+| SBOM | CycloneDX 1.6 & SPDX 3.0.1 | CycloneDX 1.7 & SPDX 2.2/2.3 (3.0.1 planned) |
+| Attestations | DSSE + in-toto | ✅ Complete |
+| Runtime | normalized function-hit schema | ✅ `RuntimeCallEvent` schema |
+| Diffs | signed binary/source diffs | Feedser has data; UI needed |
+| Policy | OPA/Rego + lattice | ✅ K4 lattice + policy rules |
+
+## Key Design Principles
+
+1. **Every claim is deep-linkable** - All evidence has content-addressed URIs
+2. **Proofs, not dashboards** - Visual elements link to signed DSSE bundles
+3. **Deterministic replay** - Any verdict can be reproduced with same inputs
+4. **Grounded AI only** - AdvisoryAI responses cite internal object links
+5. **Immutable audit trail** - Decisions recorded with signed rationale
+
+## Success Criteria
+
+- [ ] Tabbed evidence panel with 5 tabs operational
+- [ ] Diff viewer shows Feedser patch signatures
+- [ ] Runtime tab displays live eBPF function traces
+- [ ] AdvisoryAI supports multi-turn conversation
+- [ ] OpsMemory stores decisions with outcomes
+- [ ] Reproduce button triggers deterministic replay
+
+## Dependencies
+
+- **Prerequisite:** Feedser backport detection (existing)
+- **Prerequisite:** eBPF signal collection (existing)
+- **Parallel:** SPRINT_20260107_005 (CycloneDX 1.7 evidence/pedigree)

+## Decisions & Risks
+
+| Decision/Risk | Notes |
+|---------------|-------|
+| Diff syntax highlighting | Use Prism.js or similar lightweight library |
+| Runtime polling | WebSocket preferred; fallback to 5s interval |
+| Large diffs | Truncate at 500 lines; link to full view |

+# Sprint SPRINT_20260107_006_003_BE - AdvisoryAI Chat Interface
+
+> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
+> **Status:** TODO
+> **Last Updated:** 2026-01-07
+
+## Objective
+
+Implement a conversational chat interface for AdvisoryAI, enabling multi-turn dialogue while maintaining grounded responses with object links. The model can propose actions, but execution is gated by policy-aware automation.
+
+## Working Directory
+
+- `src/AdvisoryAI/StellaOps.AdvisoryAI/Chat/`
+- `src/AdvisoryAI/StellaOps.AdvisoryAI.WebService/Endpoints/`
+- `src/Web/StellaOps.Web/src/app/features/advisory-ai/`
+
+## Prerequisites
+
+- Existing: AdvisoryAI grounded responses
+- Existing: Guardrail pipeline
+
+---
+
+## Advisory Vision
+
+> "**Grounded answers only**: model responses must cite **internal object links** (SBOM IDs, DSSE URIs, call-graph nodes).
+> **Guardrails**: model can propose actions, but execution is gated by **Policy-aware Automation**."
+
+## Example User Flows
+
+**Flow 1: Integration Question**
+```
+User: "How do I integrate GitLab?"
+
+AdvisoryAI:
+  Here's how to integrate GitLab with StellaOps:
+
+  **Steps:**
+  1. Create GitLab application (Admin → Applications)
+  2. Configure OIDC claims: `groups`, `email`
+  3. Add webhook secret to StellaOps Authority
+
+  **One-click setup:**
+  [Generate Integration Manifest] ← Button
+
+  **References:**
+  - Authority keys: [auth:keys/gitlab-oidc ↗]
+  - Webhook URL: `https://stellaops.example.com/webhooks/gitlab`
+  - Required scopes: [docs:scopes/ci-webhook ↗]
+```
+
+**Flow 2: Exploitability Question**
+```
+User: "Is CVE-2023-44487 exploitable here?"
+
+AdvisoryAI:
+  **Verdict:** ⚠️ AFFECTED (reachable)
+
+  **Evidence:**
+  - Reachability: [reach:api-gateway:grpc.Server ↗] → 95% confident
+  - Runtime: 1,247 hits in last 24h [runtime:api-gateway:traces ↗]
+  - EPSS: 0.97 (top 1% exploitability)
+
+  **Recommendation:** Upgrade to patched version or apply WAF rule.
+
+  **Actions:**
+  [Approve] [Quarantine] [Defer with VEX]

+# Sprint SPRINT_20260107_006_004_BE - OpsMemory Decision Ledger
+
+> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
+> **Status:** TODO
+> **Last Updated:** 2026-01-07
+
+## Objective
+
+Implement OpsMemory, a structured ledger of prior security decisions and their outcomes. This enables playbook learning - understanding which decisions led to good outcomes and surfacing institutional knowledge for similar situations.
+
+## Working Directory
+
+- `src/OpsMemory/StellaOps.OpsMemory/`
+- `src/OpsMemory/StellaOps.OpsMemory.WebService/`
+- `src/OpsMemory/__Tests/`
+
+## Prerequisites
+
+- Existing: Decision recording (DecisionDrawerEnhancedComponent)
+- Existing: Verdict rationale (RationaleClient)
+
+---
+
+## Advisory Vision
+
+> "**OpsMemory**: structured ledger of prior decisions/outcomes (not chat logs) for playbook learning."
+
+## What OpsMemory Is NOT
+
+- ❌ Chat history (that's conversation storage)
+- ❌ Audit logs (that's the Timeline)
+- ❌ VEX statements (that's Excititor)
+
+## What OpsMemory IS
+
+- ✅ Decision + Outcome pairs
+- ✅ Success/failure classification
+- ✅ Similar situation matching
+- ✅ Playbook suggestions based on past outcomes

+> **Status:** TODO
+> **Last Updated:** 2026-01-07
+
+## Objective
+
+Complete the Reproduce button implementation, enabling auditors to trigger deterministic replay using the same feed hashes, rules, and seeds to recreate any verdict. This is the key differentiator: "auditors rerun your exact decision graph; rivals hand over PDFs."
+
+## Working Directory
+
+- `src/Timeline/StellaOps.Timeline.WebService/Endpoints/`
+- `src/Replay/StellaOps.Replay.Core/`
+- `src/Web/StellaOps.Web/src/app/shared/components/reproduce/`
+
+## Prerequisites
+
+- Existing: `ITimelineReplayOrchestrator` interface (defined)
+- Existing: `ReplayEndpoints.cs` (stubbed)
+- Existing: Timeline module with HLC ordering
+
+---
+
+## Advisory Vision
+
+> "**Reproduce** button: spins deterministic replay using the same feed hashes, rules, and seeds to recreate the verdict."
+
+## Current State
+
+The replay interface is defined but endpoints are stubbed:
+- `ITimelineReplayOrchestrator` - interface exists
+- `ReplayOperation` model - defined
+- `ReplayEndpoints` - has TODO markers
+
+## Target State
+
+Fully functional Reproduce button:
+1. User clicks "Reproduce" on any verdict
+2. System queues replay job with input manifests
+3. Replay engine recreates verdict with same inputs
+4. UI shows progress and comparison result
+5. Determinism verification: original digest vs replay digest

+# Facet Seal Admission Webhook Configuration
+
+**Sprint:** SPRINT_20260105_002_004_CLI
+**Task:** CLI-017 - Admission webhook configuration documentation
+
+## Overview
+
+The StellaOps Zastava admission webhook validates facet seals during Kubernetes pod admission. When enabled, it ensures that container images have valid facet seals and that any drift from the baseline is within acceptable quotas.
+
+## Prerequisites
+
+- Kubernetes cluster with admission webhook support
+- StellaOps Zastava webhook deployed
+- Certificate management for webhook TLS
+- Network access from API server to webhook endpoint
+
+## Enabling Facet Validation
+
+Facet seal validation is opt-in per namespace using annotations.
+
+### Namespace Annotation
+
+Add the following annotation to enable facet validation:
+
+```yaml
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: production
+  annotations:
+    stellaops.io/facet-seal-required: "true"
+```
+
+### Annotation Values
+
+| Value | Behavior |
+|-------|----------|
+| `"true"` | Facet seal validation enabled |
+| `"false"` | Facet seal validation disabled |
+| (not set) | Facet seal validation disabled |
+
+## Validation Behavior
+
+When facet validation is enabled, the webhook performs these checks:
+
+1. **Seal Lookup**: Load the facet seal for the image digest
+2. **Signature Verification**: Verify the seal's DSSE signature (if present)
+3. **Drift Computation**: Compare current image state against baseline seal
+4. **Quota Evaluation**: Check drift against configured quotas
+
+### Verdict Outcomes
+
+| Verdict | Result | Description |
+|---------|--------|-------------|
+| `Ok` | Allow | Drift within quotas |
+| `Warning` | Allow (with warning) | Approaching quota limits |
+| `Blocked` | Deny | Quota exceeded |
+| `RequiresVex` | Deny | Requires VEX authorization |
+
+## Configuration Options
+
+### Webhook Deployment
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: zastava-webhook
+  namespace: stellaops-system
+spec:
+  replicas: 3
+  selector:

+      volumes:
+      - name: webhook-certs
+        secret:
+          secretName: zastava-webhook-certs
+```
+
+### ValidatingWebhookConfiguration
+
+```yaml
+apiVersion: admissionregistration.k8s.io/v1
+kind: ValidatingWebhookConfiguration
+metadata:
+  name: stellaops-facet-admission
+webhooks:
+- name: facet.admission.stellaops.io
+  clientConfig:
+    service:
+      name: zastava-webhook
+      namespace: stellaops-system
+      path: /validate
+    caBundle: ${CA_BUNDLE}
+  rules:
+  - operations: ["CREATE", "UPDATE"]
+    apiGroups: [""]
+    apiVersions: ["v1"]
+    resources: ["pods"]
+  namespaceSelector:
+    matchExpressions:
+    - key: stellaops.io/facet-seal-required
+      operator: In
+      values: ["true"]
+  failurePolicy: Fail
+  sideEffects: None
+  admissionReviewVersions: ["v1"]
+```
+
+## Quota Configuration
+
+Facet drift quotas can be configured per namespace or globally.
+
+### Global Quotas (ConfigMap)
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: stellaops-facet-quotas
+  namespace: stellaops-system
+data:
+  default.yaml: |
+    quotas:
+      runtime:
+        warningThreshold: 10
+        blockThreshold: 25
+        vexThreshold: 50
+      config:
+        warningThreshold: 20
+        blockThreshold: 40
+        vexThreshold: 60
+      static:
+        warningThreshold: 30
+        blockThreshold: 50
+        vexThreshold: 75
+```
+
+### Per-Namespace Overrides
+
+```yaml
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: staging
+  annotations:
+    stellaops.io/facet-seal-required: "true"
+    stellaops.io/facet-quota-runtime-warn: "20"
+    stellaops.io/facet-quota-runtime-block: "50"
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Seal Not Found
+
+```
+Admission denied: facet.seal.missing
+No facet seal found for image sha256:abc123...
+```
+
+**Resolution**: Ensure the image was sealed before deployment:
+
+```bash
+stella seal sha256:abc123 --store
+```
+
+#### Invalid Signature
+
+```
+Admission denied: facet.seal.invalid_signature
+Facet seal signature verification failed
+```
+
+**Resolution**: Verify the seal was signed with a trusted key and the trust roots are configured.
+
+#### Quota Exceeded
+
+```
+Admission denied: facet.quota.exceeded
+Facet quota exceeded: runtime(45.2%)
+```
+
+**Resolution**: Either:
+1. Re-seal the image with current state
+2. Generate and approve a VEX authorization
+3. Adjust quota thresholds
+
+### Debugging
+
+Enable verbose logging:
+
+```yaml
+env:
+- name: STELLAOPS_LOG_LEVEL
+  value: "Debug"
+```
+
+View webhook logs:
+
+```bash
+kubectl logs -n stellaops-system -l app=zastava-webhook
+```
+
+## Metrics
+
+The webhook exposes Prometheus metrics:
+
+| Metric | Type | Description |
+|--------|------|-------------|
+| `stellaops_facet_admission_total` | Counter | Total admission requests |
+| `stellaops_facet_admission_allowed` | Counter | Allowed admissions |
+| `stellaops_facet_admission_denied` | Counter | Denied admissions |
+| `stellaops_facet_drift_percent` | Histogram | Drift percentage distribution |
+| `stellaops_facet_validation_duration_seconds` | Histogram | Validation latency |

+# stella drift (Facet Analysis) - Command Guide
+
+**Sprint:** SPRINT_20260105_002_004_CLI
+**Task:** CLI-016 - Facet drift command documentation
+
+## Overview
+
+The `stella drift` command analyzes facet drift between a baseline seal and the current state of a container image. Unlike reachability drift (which tracks call paths to vulnerable code), facet drift tracks file-level changes within categorized image layers.
+
+## Commands
+
+### stella drift
+
+Analyze facet drift for an image against a baseline seal.
+
+```bash
+stella drift <IMAGE> [OPTIONS]
+```
+
+#### Arguments
+
+| Argument | Description |
+|----------|-------------|
+| `IMAGE` | Image reference or digest to analyze (required) |
+
+#### Options
+
+| Option | Alias | Description | Default |
+|--------|-------|-------------|---------|
+| `--baseline <ID>` | `-b` | Baseline seal ID for comparison | latest seal |
+| `--format <FMT>` | `-f` | Output format: `table`, `json`, `yaml` | `table` |
+| `--verbose` | `-v` | Show detailed file changes | `false` |
+| `--fail-on-breach` | | Exit with error code if quota breached | `false` |
+
+#### Examples
+
+##### Basic drift analysis
+
+```bash
+stella drift sha256:abc123def456...
+```
+
+##### With specific baseline
+
+```bash
+stella drift myregistry.io/app:v2.0 --baseline seal-xyz789
+```
+
+##### JSON output for CI integration
+
+```bash
+stella drift sha256:abc123 --format json > drift-report.json
+```
+
+##### Fail build on quota breach
+
+```bash
+stella drift sha256:abc123 --fail-on-breach
+```
+
+##### Verbose output with file details
+
+```bash
+stella drift sha256:abc123 --verbose
+```
+

+   ```bash
+   stella vex gen --from-drift --image sha256:abc123 --output vex.json
+   ```
+
+4. **Review and sign the VEX**
+   ```bash

+# stella seal - Command Guide
+
+**Sprint:** SPRINT_20260105_002_004_CLI
+**Task:** CLI-016 - Facet seal command documentation
+
+## Overview
+
+The `stella seal` command creates cryptographic seals for container image facets. A facet seal captures the state of specific file categories (binaries, libraries, configs, etc.) within an image and produces Merkle roots for tamper detection and drift analysis.
+
+## Commands
+
+### stella seal
+
+Create a facet seal for an image.
+
+```bash
+stella seal <IMAGE> [OPTIONS]
+```
+
+#### Arguments
+
+| Argument | Description |
+|----------|-------------|
+| `IMAGE` | Image reference or digest to seal (required) |
+
+#### Options
+
+| Option | Alias | Description | Default |
+|--------|-------|-------------|---------|
+| `--output <PATH>` | `-o` | Output file path for seal | stdout |
+| `--store` | `-s` | Store seal in remote API | `true` |
+| `--sign` | | Sign seal with DSSE | `true` |
+| `--key <PATH>` | `-k` | Private key path for signing | configured key |
+| `--facets <LIST>` | `-f` | Specific facets to seal (comma-separated) | all |
+| `--format <FMT>` | | Output format: `json`, `yaml`, `compact` | `json` |
+| `--verbose` | `-v` | Enable verbose output | `false` |
+
+#### Examples
+
+##### Seal all facets
+
+```bash
+stella seal sha256:abc123def456...
+```
+
+##### Seal specific facets
+
+```bash
+stella seal myregistry.io/app:v1.0 --facets runtime,config
+```
+
+##### Output to file
+
+```bash
+stella seal myregistry.io/app:v1.0 --output seal.json
+```
+
+##### Seal without storing remotely
+
+```bash
+stella seal sha256:abc123 --no-store --output local-seal.json
+```
+
+##### Seal with custom signing key

+  artifacts:
+    paths:
+      - seal.json
+```
+
+---
+
+## Admission Integration
+
+When Kubernetes admission is configured with facet seal validation, the webhook will:
+
+1. Check if namespace has `stellaops.io/facet-seal-required=true` annotation
+2. Load the seal for the image being deployed
+3. Verify the seal signature
+4. Compute drift against current image state
+5. Admit/reject based on quota verdicts
+
+See [Admission Webhook Configuration](../admin/admission-webhook.md) for setup details.

+
+### Usage
+
+```bash
+stella vex gen --from-drift --image <IMAGE> [OPTIONS]
+```
+
+### Required Options
+
+| Option | Alias | Description |
+|--------|-------|-------------|
+| `--from-drift` | | Enable drift-based VEX generation |
+| `--image <REF>` | `-i` | Image reference or digest to analyze |
+
+### Optional Options
+
+| Option | Alias | Description | Default |
+|--------|-------|-------------|---------|
+| `--baseline <ID>` | `-b` | Baseline seal ID for comparison | latest seal |
+| `--output <PATH>` | `-o` | Output file path | stdout |

+
+### Workflow Integration
+
+The `vex gen --from-drift` command is typically used in a deployment pipeline:
+
+1. **Build**: Container image is built
+2. **Seal**: `stella seal` creates baseline seal at build time
+3. **Deploy**: Deployment triggers admission webhook
+4. **Drift Detection**: If drift exceeds quota, deployment is blocked
+5. **VEX Generation**: `stella vex gen --from-drift` creates authorization document
+6. **Review**: Security team reviews and signs VEX
+7. **Retry Deploy**: With VEX in place, deployment proceeds
+
+```bash
+# After deployment blocked due to drift
+stella vex gen --from-drift --image $IMAGE_DIGEST \
+  --output vex-authorization.json
+
+# Review and sign the VEX document
+stella vex sign --input vex-authorization.json --key $SIGNING_KEY
+
+# Ingest the signed VEX
+stella vex ingest --input vex-authorization.signed.json
+
+# Retry deployment (webhook will now accept)
+kubectl apply -f deployment.yaml
+```

-## CLI Commands
-
-### Export Operations
-
-```bash
-# Export full bundle (no cursor = all data)
-feedser bundle export --output bundle.zst
-
-# Export delta since last cursor
-feedser bundle export --since-cursor "2025-01-15T10:00:00Z#0001" --output delta.zst
-
-# Preview export without creating bundle
-feedser bundle preview --since-cursor "2025-01-15T10:00:00Z#0001"
-
-# Export without signing (testing only)
-feedser bundle export --no-sign --output unsigned.zst
-```
-
-### Import Operations
-
-```bash
-# Import bundle
-feedser bundle import bundle.zst
-
-# Dry run (validate without importing)
-feedser bundle import bundle.zst --dry-run
-
-# Import from stdin (pipe)
-cat bundle.zst | feedser bundle import -
-
-# Force import (skip cursor validation)
-feedser bundle import bundle.zst --force
-```
-
-### Site Management
-
-```bash
-# List federated sites
-feedser sites list
-
-# Show site details
-feedser sites show us-west-1
-
-# Enable/disable site
-feedser sites enable ap-south-1
-feedser sites disable ap-south-1
-```
-
-## Cursor Format
-
-Cursors use ISO-8601 timestamp with sequence number:
-
-```
-{ISO-8601 timestamp}#{sequence number}
-
-Examples:
-2025-01-15T10:00:00.000Z#0001
-2025-01-15T10:00:00.000Z#0002
-```
-
-- Cursors are site-specific (each site maintains independent cursors)
-- Sequence numbers distinguish concurrent exports
-- Cursors are monotonically increasing within a site
-
-## Air-Gap Transfer Workflow
-
-For environments without network connectivity:
-
-```bash
-# On Source Site (connected to authority)
-feedser bundle export --since-cursor "$LAST_CURSOR" --output /media/usb/bundle.zst
-feedser bundle preview --since-cursor "$LAST_CURSOR" > /media/usb/manifest.txt
-
-# Transfer media to target site...
-
-# On Target Site (air-gapped)
-feedser bundle import /media/usb/bundle.zst --dry-run  # Validate first
-feedser bundle import /media/usb/bundle.zst            # Import
-```
-
-## Multi-Site Synchronization
-
-### Hub-and-Spoke Topology
-
-```
-           ┌─────────────┐
-           │   Hub Site  │
-           │  (Primary)  │
-           └──────┬──────┘
-                  │
-       ┌──────────┼──────────┐
-       ▼          ▼          ▼
- ┌──────────┐ ┌──────────┐ ┌──────────┐
- │  Site A  │ │  Site B  │ │  Site C  │
- │ (Spoke)  │ │ (Spoke)  │ │ (Spoke)  │
- └──────────┘ └──────────┘ └──────────┘
-```
-
-### Mesh Topology
-
-Each site can import from multiple sources:
-
-```yaml
-federation:
-  import:
-    allowed_sites:
-      - "hub-primary"
-      - "hub-secondary"  # Redundancy
-```
-
-## Merge Behavior
-
-### Conflict Resolution
-
-When importing, conflicts are resolved based on configuration:
-
-| Strategy | Behavior |
-|----------|----------|
-| `prefer_remote` | Remote (bundle) value wins (default) |
-| `prefer_local` | Local value preserved |
-| `fail` | Import aborts on any conflict |
-
-### Merge Actions
-
-| Action | Description |
-|--------|-------------|
-| `Created` | New canonical added |
-| `Updated` | Existing canonical updated |
-| `Skipped` | No change needed (identical) |
-
-## Verification
-
-### Hash Verification
-
-Bundle hash is computed over compressed content:
-
-```
-SHA256(compressed bundle content)
-```
-
-### Signature Verification
-
-DSSE envelope contains:
-
-```json
-{
-  "payloadType": "application/stellaops.federation.bundle+json",
-  "payload": "base64(bundle_hash + site_id + cursor)",
-  "signatures": [
-    {
-      "keyId": "signing-key-001",
-      "algorithm": "ES256",
-      "signature": "base64(signature)"
-    }
-  ]
-}
-```
-
-## Monitoring
-
-### Key Metrics
-
-- `federation_export_duration_seconds` - Export time
-- `federation_import_duration_seconds` - Import time
-- `federation_bundle_size_bytes` - Bundle sizes
-- `federation_items_processed_total` - Items processed by type
-- `federation_conflicts_total` - Merge conflicts encountered
-
-### Health Checks
-
-```bash
-# Check federation status
-curl http://localhost:5000/api/v1/federation/status
-
-# Response
-{
-  "site_id": "us-west-1",
-  "export_enabled": true,
-  "import_enabled": true,
-  "last_export": "2025-01-15T10:00:00Z",
-  "last_import": "2025-01-15T09:30:00Z",
-  "sites_synced": 2
-}
-```
-
-## Troubleshooting
-
-### Common Issues
-
-**Import fails with "cursor validation failed"**
-- Bundle cursor is not after current site cursor
-- Use `--force` to override (not recommended)
-- Check if bundle was already imported
-
-**Signature verification failed**
-- Signing key not trusted on target site
-- Key expired or revoked
-- Use `--skip-signature` for testing only
-
-**Large bundle timeout**
-- Increase `federation.export.timeout`
-- Use smaller `max_items_per_bundle`
-- Stream directly to file
-
-### Debug Logging
-
-```yaml
-logging:
-  level:
-    StellaOps.Concelier.Federation: Debug
-```
-
-## Security Considerations
-
-1. **Never skip signature verification in production**
-2. **Validate allowed_sites whitelist**
-3. **Use TLS for API endpoints**
-4. **Rotate signing keys periodically**
-5. **Audit import events**
-6. **Monitor for duplicate bundle imports**

-# Concelier & Excititor Mirror Operations
-
-This runbook describes how Stella Ops operates the managed mirrors under `*.stella-ops.org`.
-It covers Docker Compose and Helm deployment overlays, secret handling for multi-tenant
-authn, CDN fronting, and the recurring sync pipeline that keeps mirror bundles current.
-
-## 1. Prerequisites
-
-- **Authority access** – client credentials (`client_id` + secret) authorised for
-  `concelier.mirror.read` and `excititor.mirror.read` scopes. Secrets live outside git.
-- **Signed TLS certificates** – wildcard or per-domain (`mirror-primary`, `mirror-community`).
-  Store them under `deploy/compose/mirror-gateway/tls/` or in Kubernetes secrets.
-- **Mirror gateway credentials** – Basic Auth htpasswd files per domain. Generate with
-  `htpasswd -B`. Operators distribute credentials to downstream consumers.
-- **Export artifact source** – read access to the canonical S3 buckets (or rsync share)
-  that hold `concelier` JSON bundles and `excititor` VEX exports.
-- **Persistent volumes** – storage for Concelier job metadata and mirror export trees.
-  For Helm, provision PVCs (`concelier-mirror-jobs`, `concelier-mirror-exports`,
-  `excititor-mirror-exports`, `mirror-mongo-data`, `mirror-minio-data`) before rollout.
-
-### 1.1 Service configuration quick reference
-
-Concelier.WebService exposes the mirror HTTP endpoints once `CONCELIER__MIRROR__ENABLED=true`.
-Key knobs:
-
-- `CONCELIER__MIRROR__EXPORTROOT` – root folder containing export snapshots (`<exportId>/mirror/*`).
-- `CONCELIER__MIRROR__ACTIVEEXPORTID` – optional explicit export id; otherwise the service auto-falls back to the `latest/` symlink or newest directory.
-- `CONCELIER__MIRROR__REQUIREAUTHENTICATION` – default auth requirement; override per domain with `CONCELIER__MIRROR__DOMAINS__{n}__REQUIREAUTHENTICATION`.
-- `CONCELIER__MIRROR__MAXINDEXREQUESTSPERHOUR` – budget for `/concelier/exports/index.json`. Domains inherit this value unless they define `__MAXDOWNLOADREQUESTSPERHOUR`.
-- `CONCELIER__MIRROR__DOMAINS__{n}__ID` – domain identifier matching the exporter manifest; additional keys configure display name and rate budgets.
-
-> The service honours Stella Ops Authority when `CONCELIER__AUTHORITY__ENABLED=true` and `ALLOWANONYMOUSFALLBACK=false`. Use the bypass CIDR list (`CONCELIER__AUTHORITY__BYPASSNETWORKS__*`) for in-cluster ingress gateways that terminate Basic Auth. Unauthorized requests emit `WWW-Authenticate: Bearer` so downstream automation can detect token failures.
-
-Mirror responses carry deterministic cache headers: `/index.json` returns `Cache-Control: public, max-age=60`, while per-domain manifests/bundles include `Cache-Control: public, max-age=300, immutable`. Rate limiting surfaces `Retry-After` when quotas are exceeded.
-
-### 1.2 Mirror connector configuration
-
-Downstream Concelier instances ingest published bundles using the `StellaOpsMirrorConnector`. Operators running the connector in air‑gapped or limited connectivity environments can tune the following options (environment prefix `CONCELIER__SOURCES__STELLAOPSMIRROR__`):
-
-- `BASEADDRESS` – absolute mirror root (e.g., `https://mirror-primary.stella-ops.org`).
-- `INDEXPATH` – relative path to the mirror index (`/concelier/exports/index.json` by default).
-- `DOMAINID` – mirror domain identifier from the index (`primary`, `community`, etc.).
-- `HTTPTIMEOUT` – request timeout; raise when mirrors sit behind slow WAN links.
-- `SIGNATURE__ENABLED` – require detached JWS verification for `bundle.json`.
-- `SIGNATURE__KEYID` / `SIGNATURE__PROVIDER` – expected signing key metadata.
-- `SIGNATURE__PUBLICKEYPATH` – PEM fallback used when the mirror key registry is offline.
-
-The connector keeps a per-export fingerprint (bundle digest + generated-at timestamp) and tracks outstanding document IDs. If a scan is interrupted, the next run resumes parse/map work using the stored fingerprint and pending document lists—no network requests are reissued unless the upstream digest changes.
-
-## 2. Secret & certificate layout
-
-### Docker Compose (`deploy/compose/docker-compose.mirror.yaml`)
-
-- `deploy/compose/env/mirror.env.example` – copy to `.env` and adjust quotas or domain IDs.
-- `deploy/compose/mirror-secrets/` – mount read-only into `/run/secrets`. Place:
-  - `concelier-authority-client` – Authority client secret.
-  - `excititor-authority-client` (optional) – reserve for future authn.
-- `deploy/compose/mirror-gateway/tls/` – PEM-encoded cert/key pairs:
-  - `mirror-primary.crt`, `mirror-primary.key`
-  - `mirror-community.crt`, `mirror-community.key`
-- `deploy/compose/mirror-gateway/secrets/` – htpasswd files:
-  - `mirror-primary.htpasswd`
-  - `mirror-community.htpasswd`
-
-### Helm (`deploy/helm/stellaops/values-mirror.yaml`)
-
-Create secrets in the target namespace:
-
-```bash
-kubectl create secret generic concelier-mirror-auth \
-  --from-file=concelier-authority-client=concelier-authority-client
-
-kubectl create secret generic excititor-mirror-auth \
-  --from-file=excititor-authority-client=excititor-authority-client
-
-kubectl create secret tls mirror-gateway-tls \
-  --cert=mirror-primary.crt --key=mirror-primary.key
-
-kubectl create secret generic mirror-gateway-htpasswd \
-  --from-file=mirror-primary.htpasswd --from-file=mirror-community.htpasswd
-```
-
-> Keep Basic Auth lists short-lived (rotate quarterly) and document credential recipients.
-
-## 3. Deployment
-
-### 3.1 Docker Compose (edge mirrors, lab validation)
-
-1. `cp deploy/compose/env/mirror.env.example deploy/compose/env/mirror.env`
-2. Populate secrets/tls directories as described above.
-3. Sync mirror bundles (see §4) into `deploy/compose/mirror-data/…` and ensure they are mounted
-   on the host path backing the `concelier-exports` and `excititor-exports` volumes.
-4. Run the profile validator: `deploy/tools/validate-profiles.sh`.
-5. Launch: `docker compose --env-file env/mirror.env -f docker-compose.mirror.yaml up -d`.
-
-### 3.2 Helm (production mirrors)
-
-1. Provision PVCs sized for mirror bundles (baseline: 20 GiB per domain).
-2. Create secrets/tls config maps (§2).
-3. `helm upgrade --install mirror deploy/helm/stellaops -f deploy/helm/stellaops/values-mirror.yaml`.
-4. Annotate the `stellaops-mirror-gateway` service with ingress/LoadBalancer metadata required by
-   your CDN (e.g., AWS load balancer scheme internal + NLB idle timeout).
-
-## 4. Artifact sync workflow
-
-Mirrors never generate exports—they ingest signed bundles produced by the Concelier and Excititor
-export jobs. Recommended sync pattern:
-
-### 4.1 Compose host (systemd timer)
-
-`/usr/local/bin/mirror-sync.sh`:
-
-```bash
-#!/usr/bin/env bash
-set -euo pipefail
-export AWS_ACCESS_KEY_ID=…
-export AWS_SECRET_ACCESS_KEY=…
-
-aws s3 sync s3://mirror-stellaops/concelier/latest \
-  /opt/stellaops/mirror-data/concelier --delete --size-only
-
-aws s3 sync s3://mirror-stellaops/excititor/latest \
-  /opt/stellaops/mirror-data/excititor --delete --size-only
-```
-
-Schedule with a systemd timer every 5 minutes. The Compose volumes mount `/opt/stellaops/mirror-data/*`
-into the containers read-only, matching `CONCELIER__MIRROR__EXPORTROOT=/exports/json` and
-`EXCITITOR__ARTIFACTS__FILESYSTEM__ROOT=/exports`.
-
-### 4.2 Kubernetes (CronJob)
-
-Create a CronJob running the AWS CLI (or rclone) in the same namespace, writing into the PVCs:
-
-```yaml
-apiVersion: batch/v1
-kind: CronJob
-metadata:
-  name: mirror-sync
-spec:
-  schedule: "*/5 * * * *"
-  jobTemplate:
-    spec:
-      template:
-        spec:
-          containers:
-          - name: sync
-            image: public.ecr.aws/aws-cli/aws-cli@sha256:5df5f52c29f5e3ba46d0ad9e0e3afc98701c4a0f879400b4c5f80d943b5fadea
-            command:
-              - /bin/sh
-              - -c
-              - >
-                aws s3 sync s3://mirror-stellaops/concelier/latest /exports/concelier --delete --size-only &&
-                aws s3 sync s3://mirror-stellaops/excititor/latest /exports/excititor --delete --size-only
-            volumeMounts:
-              - name: concelier-exports
-                mountPath: /exports/concelier
-              - name: excititor-exports
-                mountPath: /exports/excititor
-            envFrom:
-              - secretRef:
-                  name: mirror-sync-aws
-          restartPolicy: OnFailure
-          volumes:
-            - name: concelier-exports
-              persistentVolumeClaim:
-                claimName: concelier-mirror-exports
-            - name: excititor-exports
-              persistentVolumeClaim:
-                claimName: excititor-mirror-exports
-```
-
-## 5. CDN integration
-
-1. Point the CDN origin at the mirror gateway (Compose host or Kubernetes LoadBalancer).
-2. Honour the response headers emitted by the gateway and Concelier/Excititor:
-   `Cache-Control: public, max-age=300, immutable` for mirror payloads.
-3. Configure origin shields in the CDN to prevent cache stampedes. Recommended TTLs:
-   - Index (`/concelier/exports/index.json`, `/excititor/mirror/*/index`) → 60 s.
-   - Bundle/manifest payloads → 300 s.
-4. Forward the `Authorization` header—Basic Auth terminates at the gateway.
-5. Enforce per-domain rate limits at the CDN (matching gateway budgets) and enable logging
-   to SIEM for anomaly detection.
-
-## 6. Smoke tests
-
-After each deployment or sync cycle (temporarily set low budgets if you need to observe 429 responses):
-
-```bash
-# Index with Basic Auth
-curl -u $PRIMARY_CREDS https://mirror-primary.stella-ops.org/concelier/exports/index.json | jq 'keys'
-
-# Mirror manifest signature and cache headers
-curl -u $PRIMARY_CREDS -I https://mirror-primary.stella-ops.org/concelier/exports/mirror/primary/manifest.json \
-  | tee /tmp/manifest-headers.txt
-grep -E '^Cache-Control: ' /tmp/manifest-headers.txt   # expect public, max-age=300, immutable
-
-# Excititor consensus bundle metadata
-curl -u $COMMUNITY_CREDS https://mirror-community.stella-ops.org/excititor/mirror/community/index \
-  | jq '.exports[].exportKey'
-
-# Signed bundle + detached JWS (spot check digests)
-curl -u $PRIMARY_CREDS https://mirror-primary.stella-ops.org/concelier/exports/mirror/primary/bundle.json.jws \
-  -o bundle.json.jws
-cosign verify-blob --signature bundle.json.jws --key mirror-key.pub bundle.json
-
-# Service-level auth check (inside cluster – no gateway credentials)
-kubectl exec deploy/stellaops-concelier -- curl -si http://localhost:8443/concelier/exports/mirror/primary/manifest.json \
-  | head -n 5   # expect HTTP/1.1 401 with WWW-Authenticate: Bearer
-
-# Rate limit smoke (repeat quickly; second call should return 429 + Retry-After)
-for i in 1 2; do
-  curl -s -o /dev/null -D - https://mirror-primary.stella-ops.org/concelier/exports/index.json \
-    -u $PRIMARY_CREDS | grep -E '^(HTTP/|Retry-After:)'
-  sleep 1
-done
-```
-
-Watch the gateway metrics (`nginx_vts` or access logs) for cache hits. In Kubernetes, `kubectl logs deploy/stellaops-mirror-gateway`
-should show `X-Cache-Status: HIT/MISS`.
-
-## 7. Maintenance & rotation
-
-- **Bundle freshness** – alert if sync job lag exceeds 15 minutes or if `concelier` logs
-  `Mirror export root is not configured`.
-- **Secret rotation** – change Authority client secrets and Basic Auth credentials quarterly.
-  Update the mounted secrets and restart deployments (`docker compose restart concelier` or
-  `kubectl rollout restart deploy/stellaops-concelier`).
-- **TLS renewal** – reissue certificates, place new files, and reload gateway (`docker compose exec mirror-gateway nginx -s reload`).
-- **Quota tuning** – adjust per-domain `MAXDOWNLOADREQUESTSPERHOUR` in `.env` or values file.
-  Align CDN rate limits and inform downstreams.

+  - `mirror-primary.htpasswd`
+  - `mirror-community.htpasswd`
+
+### Helm (`devops/helm/stellaops/values-mirror.yaml`)
+
+Create secrets in the target namespace:
+
+```bash
+kubectl create secret generic concelier-mirror-auth \
+  --from-file=concelier-authority-client=concelier-authority-client
+
+kubectl create secret generic excititor-mirror-auth \
+  --from-file=excititor-authority-client=excititor-authority-client
+
+kubectl create secret tls mirror-gateway-tls \
+  --cert=mirror-primary.crt --key=mirror-primary.key
+
+kubectl create secret generic mirror-gateway-htpasswd \
+  --from-file=mirror-primary.htpasswd --from-file=mirror-community.htpasswd
+```
+
+> Keep Basic Auth lists short-lived (rotate quarterly) and document credential recipients.
+
+## 3. Deployment
+
+### 3.1 Docker Compose (edge mirrors, lab validation)
+
+1. `cp devops/compose/env/mirror.env.example devops/compose/env/mirror.env`
+2. Populate secrets/tls directories as described above.
+3. Sync mirror bundles (see §4) into `devops/compose/mirror-data/…` and ensure they are mounted
+   on the host path backing the `concelier-exports` and `excititor-exports` volumes.
+4. Run the profile validator: `deploy/tools/validate-profiles.sh`.
+5. Launch: `docker compose --env-file env/mirror.env -f docker-compose.mirror.yaml up -d`.
+
+### 3.2 Helm (production mirrors)
+
+1. Provision PVCs sized for mirror bundles (baseline: 20 GiB per domain).
+2. Create secrets/tls config maps (§2).
+3. `helm upgrade --install mirror devops/helm/stellaops -f devops/helm/stellaops/values-mirror.yaml`.
+4. Annotate the `stellaops-mirror-gateway` service with ingress/LoadBalancer metadata required by
+   your CDN (e.g., AWS load balancer scheme internal + NLB idle timeout).
+
+## 4. Artifact sync workflow
+
+Mirrors never generate exports—they ingest signed bundles produced by the Concelier and Excititor
+export jobs. Recommended sync pattern:
+
+### 4.1 Compose host (systemd timer)
+
+`/usr/local/bin/mirror-sync.sh`:
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+export AWS_ACCESS_KEY_ID=…
+export AWS_SECRET_ACCESS_KEY=…
+
+aws s3 sync s3://mirror-stellaops/concelier/latest \
+  /opt/stellaops/mirror-data/concelier --delete --size-only
+
+aws s3 sync s3://mirror-stellaops/excititor/latest \
+  /opt/stellaops/mirror-data/excititor --delete --size-only
+```
+
+Schedule with a systemd timer every 5 minutes. The Compose volumes mount `/opt/stellaops/mirror-data/*`
+into the containers read-only, matching `CONCELIER__MIRROR__EXPORTROOT=/exports/json` and
+`EXCITITOR__ARTIFACTS__FILESYSTEM__ROOT=/exports`.
+
+### 4.2 Kubernetes (CronJob)
+
+Create a CronJob running the AWS CLI (or rclone) in the same namespace, writing into the PVCs:
+
+```yaml
+apiVersion: batch/v1
+kind: CronJob
+metadata:
+  name: mirror-sync
+spec:
+  schedule: "*/5 * * * *"
+  jobTemplate:
+    spec:
+      template:
+        spec:
+          containers:
+          - name: sync
+            image: public.ecr.aws/aws-cli/aws-cli@sha256:5df5f52c29f5e3ba46d0ad9e0e3afc98701c4a0f879400b4c5f80d943b5fadea
+            command:
+              - /bin/sh
+              - -c
+              - >
+                aws s3 sync s3://mirror-stellaops/concelier/latest /exports/concelier --delete --size-only &&
+                aws s3 sync s3://mirror-stellaops/excititor/latest /exports/excititor --delete --size-only
+            volumeMounts:
+              - name: concelier-exports
+                mountPath: /exports/concelier
+              - name: excititor-exports
+                mountPath: /exports/excititor
+            envFrom:
+              - secretRef:
+                  name: mirror-sync-aws
+          restartPolicy: OnFailure
+          volumes:
+            - name: concelier-exports
+              persistentVolumeClaim:
+                claimName: concelier-mirror-exports
+            - name: excititor-exports
+              persistentVolumeClaim:
+                claimName: excititor-mirror-exports
+```
+
+## 5. CDN integration
+
+1. Point the CDN origin at the mirror gateway (Compose host or Kubernetes LoadBalancer).
+2. Honour the response headers emitted by the gateway and Concelier/Excititor:
+   `Cache-Control: public, max-age=300, immutable` for mirror payloads.
+3. Configure origin shields in the CDN to prevent cache stampedes. Recommended TTLs:
+   - Index (`/concelier/exports/index.json`, `/excititor/mirror/*/index`) → 60 s.
+   - Bundle/manifest payloads → 300 s.
+4. Forward the `Authorization` header—Basic Auth terminates at the gateway.
+5. Enforce per-domain rate limits at the CDN (matching gateway budgets) and enable logging
+   to SIEM for anomaly detection.
+
+## 6. Smoke tests
+
+After each deployment or sync cycle (temporarily set low budgets if you need to observe 429 responses):
+
+```bash
+# Index with Basic Auth
+curl -u $PRIMARY_CREDS https://mirror-primary.stella-ops.org/concelier/exports/index.json | jq 'keys'
+
+# Mirror manifest signature and cache headers
+curl -u $PRIMARY_CREDS -I https://mirror-primary.stella-ops.org/concelier/exports/mirror/primary/manifest.json \
+  | tee /tmp/manifest-headers.txt
+grep -E '^Cache-Control: ' /tmp/manifest-headers.txt   # expect public, max-age=300, immutable
+
+# Excititor consensus bundle metadata
+curl -u $COMMUNITY_CREDS https://mirror-community.stella-ops.org/excititor/mirror/community/index \
+  | jq '.exports[].exportKey'
+
+# Signed bundle + detached JWS (spot check digests)
+curl -u $PRIMARY_CREDS https://mirror-primary.stella-ops.org/concelier/exports/mirror/primary/bundle.json.jws \
+  -o bundle.json.jws
+cosign verify-blob --signature bundle.json.jws --key mirror-key.pub bundle.json
+
+# Service-level auth check (inside cluster – no gateway credentials)
+kubectl exec deploy/stellaops-concelier -- curl -si http://localhost:8443/concelier/exports/mirror/primary/manifest.json \
+  | head -n 5   # expect HTTP/1.1 401 with WWW-Authenticate: Bearer
+
+# Rate limit smoke (repeat quickly; second call should return 429 + Retry-After)
+for i in 1 2; do
+  curl -s -o /dev/null -D - https://mirror-primary.stella-ops.org/concelier/exports/index.json \
+    -u $PRIMARY_CREDS | grep -E '^(HTTP/|Retry-After:)'
+  sleep 1
+done
+```
+
+Watch the gateway metrics (`nginx_vts` or access logs) for cache hits. In Kubernetes, `kubectl logs deploy/stellaops-mirror-gateway`
+should show `X-Cache-Status: HIT/MISS`.
+
+## 7. Maintenance & rotation
+
+- **Bundle freshness** – alert if sync job lag exceeds 15 minutes or if `concelier` logs
+  `Mirror export root is not configured`.
+- **Secret rotation** – change Authority client secrets and Basic Auth credentials quarterly.
+  Update the mounted secrets and restart deployments (`docker compose restart concelier` or
+  `kubectl rollout restart deploy/stellaops-concelier`).
+- **TLS renewal** – reissue certificates, place new files, and reload gateway (`docker compose exec mirror-gateway nginx -s reload`).
+- **Quota tuning** – adjust per-domain `MAXDOWNLOADREQUESTSPERHOUR` in `.env` or values file.
+  Align CDN rate limits and inform downstreams.

+# Event Envelope Schema
+
+> **Version:** 1.0.0
+> **Status:** Draft
+> **Sprint:** [SPRINT_20260107_003_001_LB](../../implplan/SPRINT_20260107_003_001_LB_event_envelope_sdk.md)
+
+This document specifies the canonical event envelope schema for the StellaOps Unified Event Timeline.
+
+---
+
+## Overview
+
+The event envelope provides a standardized format for all events emitted across StellaOps services. It enables:
+
+- **Unified Timeline:** Cross-service correlation with HLC ordering
+- **Deterministic Replay:** Reproducible event streams for forensics
+- **Audit Compliance:** DSSE-signed event bundles for export
+- **Causal Analysis:** Stage latency measurement and bottleneck identification
+
+---

+
+---
+
+## Field Specifications
+
+### eventId
+
+**Purpose:** Unique, deterministic identifier for each event.
+
+**Computation:**
+```csharp
+public static string GenerateEventId(
+    string correlationId,
+    HlcTimestamp tHlc,
+    string service,
+    string kind)
+{
+    using var hasher = IncrementalHash.CreateHash(HashAlgorithmName.SHA256);
+    hasher.AppendData(Encoding.UTF8.GetBytes(correlationId));
+    hasher.AppendData(Encoding.UTF8.GetBytes(tHlc.ToSortableString()));
+    hasher.AppendData(Encoding.UTF8.GetBytes(service));
+    hasher.AppendData(Encoding.UTF8.GetBytes(kind));
+    var hash = hasher.GetHashAndReset();
+    return Convert.ToHexString(hash.AsSpan(0, 16)).ToLowerInvariant();
+}
+```
+
+**Rationale:** Unlike ULID or UUID, this deterministic approach ensures that:
+- The same event produces the same ID across replays
+- Duplicate events can be detected and deduplicated
+- Event ordering is verifiable
+
+### tHlc
+
+**Purpose:** Primary ordering timestamp using Hybrid Logical Clock.
+
+**Format:** `<physicalTimeMs>:<logicalCounter>:<nodeId>`
+
+**Example:** `1704585600000:42:scheduler-node-1`
+
+**Ordering:** Lexicographic comparison produces correct temporal order:
+1. Compare physical time (milliseconds since Unix epoch)
+2. If equal, compare logical counter
+3. If equal, compare node ID (for uniqueness)
+
+**Implementation:** Uses existing `StellaOps.HybridLogicalClock.HlcTimestamp` type.
+
+### tsWall
+
+**Purpose:** Human-readable wall-clock timestamp for debugging.
+
+**Format:** ISO 8601 with UTC timezone (e.g., `2026-01-07T12:00:00.000Z`)
+
+**Important:** This field is **informational only**. Never use for ordering or comparison. The `tHlc` field is the authoritative timestamp.
+
+### service
+
+**Purpose:** Identifies the StellaOps service that emitted the event.
+
+**Allowed Values:**
+| Value | Description |
+|-------|-------------|
+| `Scheduler` | Job scheduling and queue management |
+| `AirGap` | Offline/air-gap sync operations |
+| `Attestor` | DSSE attestation and verification |
+| `Policy` | Policy engine evaluation |
+| `VexLens` | VEX consensus computation |
+| `Scanner` | Container scanning |
+| `Concelier` | Advisory ingestion |
+| `Platform` | Console backend aggregation |
+
+### traceParent
+
+**Purpose:** W3C Trace Context correlation for OpenTelemetry integration.
+
+**Format:** `00-{trace-id}-{span-id}-{trace-flags}`
+
+**Example:** `00-4bf92f3577b34da6a3ce929d0e0e4736-00f067aa0ba902b7-01`
+
+**Population:** Automatically captured from `Activity.Current?.Id` during event emission.
+
+### correlationId
+
+**Purpose:** Links related events across services.
+
+**Common Patterns:**
+| Pattern | Example | Usage |
+|---------|---------|-------|
+| Scan ID | `scan-abc123` | Container scan lifecycle |
+| Job ID | `job-xyz789` | Scheduled job lifecycle |
+| Artifact Digest | `sha256:abc...` | Artifact processing |
+| Bundle ID | `bundle-def456` | Air-gap bundle operations |
+
+### kind
+
+**Purpose:** Categorizes the event type.
+
+**Event Kinds by Service:**
+
+| Service | Kinds |
+|---------|-------|
+| Scheduler | `ENQUEUE`, `DEQUEUE`, `EXECUTE`, `COMPLETE`, `FAIL` |
+| AirGap | `IMPORT`, `EXPORT`, `MERGE`, `CONFLICT` |
+| Attestor | `ATTEST`, `VERIFY` |
+| Policy | `EVALUATE`, `GATE_PASS`, `GATE_FAIL` |
+| VexLens | `CONSENSUS`, `OVERRIDE` |
+| Scanner | `SCAN_START`, `SCAN_COMPLETE` |
+| Generic | `EMIT`, `ACK`, `ERR` |
+
+### payload
+
+**Purpose:** Domain-specific event data.
+
+**Requirements:**
+1. **RFC 8785 Canonicalization:** Must use `CanonJson.Serialize()` from `StellaOps.Canonical.Json`
+2. **No Non-Deterministic Fields:** No random IDs, current timestamps, or environment-specific data
+3. **Bounded Size:** Payload should be < 1MB; use references for large data
+
+**Example:**
+```json
+{
+  "artifactDigest": "sha256:abc123...",
+  "jobId": "job-xyz789",
+  "status": "completed",
+  "findingsCount": 42
+}
+```
+
+### payloadDigest
+
+**Purpose:** Integrity verification of payload.
+
+**Computation:**
+```csharp
+var digest = SHA256.HashData(Encoding.UTF8.GetBytes(payload));
+```
+
+**Format:** 64-character lowercase hex string.
+
+### engineVersion
+
+**Purpose:** Records the engine/resolver version for reproducibility verification (per CLAUDE.md Rule 8.2.1).
+
+**Fields:**
+| Field | Description | Example |
+|-------|-------------|---------|
+| `engineName` | Service/engine name | `"Scheduler"` |
+| `version` | Semantic version | `"2.5.0"` |
+| `sourceDigest` | Build artifact hash | `"sha256:abc..."` |
+
+**Population:** Use `EngineVersionRef.FromAssembly(Assembly.GetExecutingAssembly())`.
+
+### dsseSig
+
+**Purpose:** Optional cryptographic signature for audit compliance.
+
+**Format:** `{keyId}:{base64Signature}`
+
+**Example:** `signing-key-001:MEUCIQD...`
+
+**Integration:** Uses existing `StellaOps.Attestation.DsseHelper` for signature generation.
+
+### schemaVersion
+
+**Purpose:** Enables schema evolution without breaking compatibility.
+
+**Current Value:** `1`
+
+**Migration Strategy:** When schema changes:
+1. Increment version number
+2. Add migration logic for older versions
+3. Document breaking changes
+

+    engine_digest   TEXT NOT NULL,
+    dsse_sig        TEXT,
+    schema_version  INTEGER NOT NULL DEFAULT 1,

+```
+
+---
+
+## Usage Examples
+
+### Emitting an Event
+
+```csharp
+public class SchedulerService
+{
+    private readonly ITimelineEventEmitter _emitter;
+
+    public async Task EnqueueJobAsync(Job job, CancellationToken ct)
+    {
+        // Business logic...
+        await _queue.EnqueueAsync(job, ct);
+
+        // Emit timeline event
+        await _emitter.EmitAsync(
+            correlationId: job.Id.ToString(),
+            kind: "ENQUEUE",
+            payload: new { jobId = job.Id, priority = job.Priority },
+            ct);
+    }
+}
+```
+
+### Querying Timeline
+
+```csharp
+public async Task<IReadOnlyList<TimelineEvent>> GetJobTimelineAsync(
+    string jobId,
+    CancellationToken ct)
+{
+    return await _timelineService.GetEventsAsync(
+        correlationId: jobId,
+        options: new TimelineQueryOptions
+        {
+            Services = ["Scheduler", "Attestor"],
+            Kinds = ["ENQUEUE", "EXECUTE", "COMPLETE", "ATTEST"]
+        },
+        ct);
+}
+```
+
+---
+
+## Compatibility Notes
+
+### Relation to Existing HLC Infrastructure
+
+This schema builds on the existing `StellaOps.HybridLogicalClock` library:
+- Uses `HlcTimestamp` type directly
+- Integrates with `IHybridLogicalClock.Tick()` for timestamp generation
+- Compatible with air-gap merge algorithms
+
+### Relation to Existing Replay Infrastructure
+
+This schema integrates with `StellaOps.Replay.Core`:
+- `KnowledgeSnapshot` can include timeline event references
+- Replay uses `FakeTimeProvider` with HLC timestamps
+- Verification compares payload digests

+# Timeline UI Component
+
+> **Module:** Eventing / Timeline
+> **Status:** Implemented
+> **Last Updated:** 2026-01-07
+
+## Overview
+
+The Timeline UI provides a visual representation of HLC-ordered events across StellaOps services. It enables operators to trace the causal flow of operations, identify bottlenecks, and investigate specific events with full evidence links.
+
+## Features
+
+### Causal Lanes Visualization
+
+Events are displayed in swimlanes organized by service:
+
+```
+┌─────────────────────────────────────────────────────────────────────┐
+│  HLC Timeline Axis                                                   │
+│  |-------|-------|-------|-------|-------|-------|-------|-------> │
+├─────────────────────────────────────────────────────────────────────┤
+│ Scheduler  [E]─────────[X]───────────────[C]                        │
+├─────────────────────────────────────────────────────────────────────┤
+│ AirGap            [I]──────────[M]                                  │
+├─────────────────────────────────────────────────────────────────────┤
+│ Attestor                              [A]──────────[V]              │
+├─────────────────────────────────────────────────────────────────────┤
+│ Policy                                       [G]                    │
+└─────────────────────────────────────────────────────────────────────┘
+```
+
+Legend:
+- **[E]** Enqueue - Job queued for processing
+- **[X]** Execute - Job execution started
+- **[C]** Complete - Job completed
+- **[I]** Import - Data imported (e.g., SBOM, advisory)
+- **[M]** Merge - Data merged
+- **[A]** Attest - Attestation created
+- **[V]** Verify - Attestation verified
+- **[G]** Gate - Policy gate evaluated
+
+### Critical Path Analysis
+
+The critical path view shows the longest sequence of dependent operations:
+
+- Color-coded by severity (green/yellow/red)
+- Bottleneck stage highlighted
+- Percentage of total duration shown
+- Clickable stages for drill-down
+
+### Event Detail Panel
+
+Selected events display:
+- Event ID and metadata
+- HLC timestamp and wall-clock time
+- Service and event kind
+- JSON payload viewer
+- Engine version information
+- Evidence links (SBOM, VEX, Policy, Attestation)
+
+### Filtering
+
+Events can be filtered by:
+- **Services**: Scheduler, AirGap, Attestor, Policy, Scanner, etc.
+- **Event Kinds**: ENQUEUE, EXECUTE, COMPLETE, IMPORT, ATTEST, etc.
+- **HLC Range**: From/To timestamps
+
+Filter state is persisted in URL query parameters.
+
+### Export
+
+Timeline data can be exported as:
+- **NDJSON**: Newline-delimited JSON (streaming-friendly)
+- **JSON**: Standard JSON array
+- **DSSE-signed**: Cryptographically signed bundles for auditing
+
+## Usage
+
+### Accessing the Timeline
+
+Navigate to `/timeline/{correlationId}` where `correlationId` is the unique identifier for a scan, job, or workflow.
+
+Example:
+```
+/timeline/scan-abc123-def456
+```
+
+### Keyboard Navigation
+
+| Key | Action |
+|-----|--------|
+| Tab | Navigate between events |
+| Enter/Space | Select focused event |
+| Escape | Clear selection |
+| Arrow keys | Scroll within panel |
+
+### URL Parameters
+
+| Parameter | Description | Example |
+|-----------|-------------|---------|
+| `services` | Comma-separated service filter | `?services=Scheduler,AirGap` |
+| `kinds` | Comma-separated kind filter | `?kinds=EXECUTE,COMPLETE` |
+| `fromHlc` | Start of HLC range | `?fromHlc=1704067200000:0:node1` |
+| `toHlc` | End of HLC range | `?toHlc=1704153600000:0:node1` |

+└── timeline.routes.ts         # Lazy-loaded routes
+```
+
+## API Integration
+
+The Timeline UI integrates with the Timeline API:
+
+| Endpoint | Description |
+|----------|-------------|
+| `GET /api/v1/timeline/{correlationId}` | Fetch events |
+| `GET /api/v1/timeline/{correlationId}/critical-path` | Fetch critical path |
+| `POST /api/v1/timeline/{correlationId}/export` | Initiate export |
+| `GET /api/v1/timeline/export/{exportId}` | Check export status |
+| `GET /api/v1/timeline/export/{exportId}/download` | Download bundle |
+
+## Accessibility
+
+The Timeline UI follows WCAG 2.1 AA guidelines:
+
+- **Keyboard Navigation**: All interactive elements are focusable
+- **Screen Readers**: ARIA labels on all regions and controls
+- **Color Contrast**: 4.5:1 minimum contrast ratio
+- **Focus Indicators**: Visible focus rings on all controls
+- **Motion**: Respects `prefers-reduced-motion`
+
+## Performance
+
+- **Virtual Scrolling**: Handles 10K+ events efficiently
+- **Lazy Loading**: Events loaded on-demand as user scrolls
+- **Caching**: Recent queries cached to reduce API calls
+- **Debouncing**: Filter changes debounced to avoid excessive requests

+# Evidence Bundle Export Format Specification
+
+> **Version:** 1.0.0  
+> **Status:** FINAL  
+> **Sprint Reference:** [SPRINT_20260106_003_003](../../../docs/implplan/SPRINT_20260106_003_003_EVIDENCE_export_bundle.md)
+
+## Overview
+
+This document specifies the standard export format for StellaOps evidence bundles. The export format enables offline verification of software supply chain artifacts including SBOMs, VEX statements, attestations, and policy verdicts.
+
+## Export Archive Format
+
+### Filename Convention
+
+```
+evidence-bundle-<bundle-id>.tar.gz
+```
+
+Where `<bundle-id>` follows the pattern: `eb-<YYYY-MM-DD>-<unique-suffix>`
+
+Example: `evidence-bundle-eb-2026-01-06-abc123.tar.gz`
+
+### Compression
+
+- **Format:** gzip-compressed tar archive
+- **Compression level:** Configurable (1-9, default: 6)
+- **Determinism:** Fixed gzip header timestamp (`2026-01-01T00:00:00Z`)
+- **Permissions:** All files `0644`, directories `0755`, uid/gid `0:0`
+

+
+## Determinism Requirements
+
+### Timestamp Handling
+
+- All timestamps MUST be UTC ISO-8601 with microsecond precision
+- Format: `YYYY-MM-DDTHH:MM:SS.ffffffZ`
+- Archive metadata timestamps are fixed for reproducibility
+
+### Ordering
+
+- Manifest artifacts: sorted lexicographically by `path`
+- Checksum entries: sorted lexicographically by filename
+- JSON object keys: sorted lexicographically (RFC 8785)
+- NDJSON records: sorted by primary key (e.g., `observationId`)
+
+### Hash Computation
+
+- Algorithm: SHA-256 (lowercase hex)
+- Input: raw file bytes (no BOM, LF line endings)
+- Merkle tree: RFC 6962 compliant binary Merkle tree
+
+## Artifact Types
+
+### SBOMs
+
+| Format | File Extension | MIME Type |
+|--------|---------------|-----------|
+| CycloneDX 1.7 | `.cdx.json` | `application/vnd.cyclonedx+json` |
+| SPDX 3.0.1 | `.spdx.json` | `application/spdx+json` |
+
+### Attestations
+
+| Type | Predicate Type | File Pattern |
+|------|---------------|--------------|
+| SBOM | `StellaOps.SBOMAttestation@1` | `sbom.dsse.json` |
+| VEX | `StellaOps.VEXAttestation@1` | `vex.dsse.json` |
+| Policy | `StellaOps.PolicyEvaluation@1` | `policy.dsse.json` |
+| Gate | `StellaOps.VexGate@1` | `gate.dsse.json` |
+
+### VEX Statements
+
+- Format: OpenVEX 0.2.0+
+- File extension: `.openvex.json`
+- Location: `vex/statements/`
+
+## Export Options
+
+### CLI Command
+
+```bash
+# Basic export
+stella evidence export --bundle <bundle-id> --output ./audit-bundle.tar.gz
+
+# With options
+stella evidence export --bundle <bundle-id> \
+  --output ./bundle.tar.gz \
+  --include-layers \
+  --include-rekor-proofs \
+  --compression 9
+
+# Verify exported bundle
+stella evidence verify ./audit-bundle.tar.gz
+
+# Verify offline (skip Rekor)
+stella evidence verify ./audit-bundle.tar.gz --offline
+```
+
+### API Endpoint
+
+```http
+POST /api/v1/bundles/{bundleId}/export
+Content-Type: application/json
+
+{
+  "format": "tar.gz",
+  "compression": "gzip",
+  "compressionLevel": 6,
+  "includeRekorProofs": true,
+  "includeLayerSboms": true
+}
+```
+
+## Offline Verification
+
+For air-gapped environments:
+
+1. Transfer `evidence-bundle-<id>.tar.gz` to isolated system
+2. Extract archive: `tar -xzf evidence-bundle-<id>.tar.gz`
+3. Run verification: `./verify.sh` (Unix) or `.\verify.ps1` (Windows)
+4. Pass `OFFLINE=true` to skip Rekor verification: `OFFLINE=true ./verify.sh`
+
+## Compatibility
+
+- **StellaOps CLI:** 2026.04+
+- **Export Library:** StellaOps.EvidenceLocker.Export 1.0.0+
+- **Verify scripts:** bash 4.0+ / PowerShell 5.1+

+# Feedser
+
+> Evidence collection library for backport detection and binary fingerprinting.
+
+## Purpose
+
+Feedser provides deterministic, cryptographic evidence collection for backport detection. It extracts patch signatures from unified diffs and binary fingerprints from compiled code to enable high-confidence vulnerability status determination for packages where upstream fixes have been backported by distro maintainers.
+
+## Quick Links

+
+| Attribute | Value |
+|-----------|-------|
+| **Maturity** | Production |
+| **Last Reviewed** | 2025-12-29 |
+| **Maintainer** | Concelier Guild |
+
+## Key Features
+
+- **Patch Signature Extraction**: Parse unified diffs and extract normalized hunk signatures
+- **Binary Fingerprinting**: TLSH fuzzy hashing and instruction sequence hashing
+- **Four-Tier Proof System**: Supporting backport detection at multiple confidence levels
+- **Deterministic Outputs**: Canonical JSON serialization with stable hashing
+
+## Dependencies
+
+### Upstream (this module depends on)
+- None (library with no external service dependencies)
+
+### Downstream (modules that depend on this)
+- **Concelier** - ProofService layer consumes Feedser for backport evidence
+- **Attestor** - Evidence storage for generated proofs
+
+## Notes
+
+Feedser is a **library**, not a standalone service. It does not expose REST APIs directly and does not make vulnerability decisions. It provides evidence that feeds into VEX statements and Policy Engine evaluation.

+# Determinization Gate API Reference
+
+> **Audience:** Backend integrators, policy operators, and security engineers working with CVE observations.
+> **Sprint:** 20260106_001_003_POLICY_determinization_gates
+
+This document describes the Determinization Gate API and the `GuardedPass` verdict status for uncertain CVE observations.
+
+---
+
+## 1. Overview
+
+The Determinization Gate evaluates CVE observations against uncertainty thresholds and produces verdicts based on available evidence (EPSS, VEX, reachability, runtime, backport signals). It introduces `GuardedPass` status for observations that don't have enough evidence for a confident determination but don't exceed risk thresholds.
+
+### Key Components
+
+| Component | Purpose |
+|-----------|---------|
+| `DeterminizationGate` | Policy gate that evaluates uncertainty and produces verdicts |
+| `DeterminizationPolicy` | Rule set for allow/quarantine/escalate decisions |
+| `SignalUpdateHandler` | Handles signal updates and triggers re-evaluation |
+| `DeterminizationGateMetrics` | OpenTelemetry metrics for observability |
+
+---
+
+## 2. PolicyVerdictStatus
+
+Policy evaluations return a `PolicyVerdictStatus` indicating the outcome:
+
+| Status | Code | Description | Monitoring Required |
+|--------|------|-------------|---------------------|
+| `Pass` | 0 | Finding meets policy requirements. No action needed. | No |
+| `Blocked` | 1 | Finding fails policy checks; must be remediated. | No |
+| `Ignored` | 2 | Finding deliberately ignored via policy exception. | No |
+| `Warned` | 3 | Finding passes but with warnings. | No |
+| `Deferred` | 4 | Decision deferred; needs additional evidence. | No |
+| `Escalated` | 5 | Decision escalated for human review. | No |
+| `RequiresVex` | 6 | VEX statement required to make decision. | No |
+| `GuardedPass` | 7 | Finding allowed with runtime monitoring guardrails. | **Yes** |
+
+---
+
+## 3. GuardedPass Status
+
+`GuardedPass` is a specialized status for CVE observations with uncertain evidence. It enables "allow with guardrails" semantics.
+
+### 3.1 When Issued
+
+- Observation has insufficient evidence for full determination (high entropy)
+- Trust score below thresholds but above blocking level
+- Non-production environments with moderate uncertainty
+- Reachability status is unknown but not confirmed reachable
+
+### 3.2 GuardRails Object
+
+When `GuardedPass` is returned, the verdict includes a `guardRails` object:
+
+```json
+{
+  "status": "GuardedPass",
+  "reason": "Uncertain observation allowed with guardrails in staging",
+  "matchedRule": "GuardedAllowNonProd",
+  "guardRails": {
+    "enableRuntimeMonitoring": true,
+    "reviewInterval": "7.00:00:00",
+    "epssEscalationThreshold": 0.4,
+    "escalatingReachabilityStates": ["Reachable", "ObservedReachable"],
+    "maxGuardedDuration": "30.00:00:00",
+    "policyRationale": "Auto-allowed: entropy=0.45, trust=0.38, env=staging"
+  },
+  "suggestedObservationState": "PendingDeterminization",
+  "uncertaintyScore": {
+    "entropy": 0.45,
+    "completeness": 0.55,
+    "tier": "Medium",
+    "missingSignals": ["runtime", "backport"]
+  }
+}
+```
+
+### 3.3 Consumer Responsibilities
+
+When receiving `GuardedPass`:
+
+1. **Enable Runtime Monitoring:** Start observing the component for vulnerable code execution
+2. **Schedule Review:** Set up periodic review at `reviewInterval`
+3. **EPSS Escalation:** Auto-escalate if EPSS score exceeds `epssEscalationThreshold`
+4. **Reachability Escalation:** Auto-escalate if reachability transitions to escalating states
+5. **Duration Limit:** Convert to `Blocked` if guard duration exceeds `maxGuardedDuration`
+
+---
+
+## 4. Determinization Rules
+
+The gate evaluates rules in priority order:
+
+| Priority | Rule | Condition | Result |
+|----------|------|-----------|--------|
+| 10 | RuntimeEscalation | Runtime evidence shows vulnerable code loaded | Escalated |
+| 20 | EpssQuarantine | EPSS score exceeds threshold | Blocked |
+| 25 | ReachabilityQuarantine | Code proven reachable | Blocked |
+| 30 | ProductionEntropyBlock | High entropy in production | Blocked |
+| 40 | StaleEvidenceDefer | Evidence is stale | Deferred |
+| 50 | GuardedAllowNonProd | Uncertain in non-prod | GuardedPass |
+| 60 | UnreachableAllow | Unreachable with high confidence | Pass |
+| 65 | VexNotAffectedAllow | VEX not_affected from trusted issuer | Pass |
+| 70 | SufficientEvidenceAllow | Low entropy, high trust | Pass |
+| 80 | GuardedAllowModerateUncertainty | Moderate uncertainty, reasonable trust | GuardedPass |
+| 100 | DefaultDefer | No rule matched | Deferred |
+
+---
+
+## 5. Environment Thresholds
+
+Thresholds vary by deployment environment:
+
+| Environment | MinConfidence | MaxEntropy | EPSS Threshold | Require Reachability |
+|-------------|---------------|------------|----------------|---------------------|
+| Production | 0.75 | 0.3 | 0.3 | Yes |
+| Staging | 0.60 | 0.5 | 0.4 | Yes |
+| Development | 0.40 | 0.7 | 0.6 | No |
+
+---
+
+## 6. Signal Update Events
+
+The Determinization Gate subscribes to signal updates for automatic re-evaluation:
+
+| Event Type | Description |
+|------------|-------------|
+| `epss.updated` | EPSS score changed |
+| `vex.updated` | VEX statement added/modified |
+| `reachability.updated` | Reachability analysis completed |
+| `runtime.updated` | Runtime observation recorded |
+| `backport.updated` | Backport detection result |
+| `observation.state_changed` | Observation state transition |
+
+---
+
+## 7. Metrics
+
+OpenTelemetry metrics for monitoring:
+
+| Metric | Type | Description |
+|--------|------|-------------|
+| `stellaops_policy_determinization_evaluations_total` | Counter | Total evaluations by status/environment/rule |
+| `stellaops_policy_determinization_rule_matches_total` | Counter | Rule matches by rule name/status/environment |
+| `stellaops_policy_observation_state_transitions_total` | Counter | State transitions by from/to state/trigger |
+| `stellaops_policy_determinization_entropy` | Histogram | Distribution of entropy scores |
+| `stellaops_policy_determinization_trust_score` | Histogram | Distribution of trust scores |
+| `stellaops_policy_determinization_evaluation_duration_ms` | Histogram | Evaluation latency |
+
+---
+
+## 8. Service Registration
+
+Add determinization services via dependency injection:
+
+```csharp
+// Register all determinization services
+services.AddDeterminizationEngine();
+
+// Or as part of full Policy Engine registration
+services.AddPolicyEngine();  // Includes determinization
+```

+- **Helm ConfigMap.** `devops/helm/stellaops/values*.yaml` now include a `policy-engine-activation` ConfigMap. The chart automatically injects it via `envFrom` into both the Policy Engine and Policy Gateway pods, so overriding the ConfigMap data updates the services with no manifest edits.
 - **Type safety.** Quote ConfigMap values (e.g., `"true"`, `"false"`) because Kubernetes ConfigMaps carry string data. This mirrors the defaults checked into the repo and keeps `helm template` deterministic.
 - **File-based overrides (optional).** The Policy Engine host already probes `/config/policy-engine/activation.yaml`, `../etc/policy-engine.activation.yaml`, and ambient `policy-engine.activation.yaml` files beside the binary. Mounting the ConfigMap as a file at `/config/policy-engine/activation.yaml` works immediately if/when we add a volume.
 - **Offline/Compose.** Compose/offline bundles can continue exporting `STELLAOPS_POLICY_ENGINE__ACTIVATION__*` variables directly; the ConfigMap wiring simply mirrors those keys for Kubernetes clusters.

+# Replay
+
+> Deterministic replay engine for vulnerability verdict reproducibility.
+
+## Purpose
+
+Replay enables deterministic reproducibility of vulnerability verdicts. Given identical inputs (SBOM, policy, feeds, toolchain), the system MUST produce identical outputs. Replay provides the infrastructure to capture, store, and verify these deterministic execution chains.

+## Key Features
+
+- **Pluggable Providers**: EPSS, CVSS+KEV, VEX status, fix availability providers
+- **Deterministic Scoring**: Same inputs produce identical scores
+- **Explainability**: Audit trails for every scoring decision
+- **Offline Support**: Air-gapped operation via factor bundles

+status: fixed       -->  VexFixedVulnAssessmentRelationship
+justification       -->  statusNotes
+action_statement    -->  actionStatement
+```
+
+---
+
+## JSON-LD Structure
+
+SPDX 3.0.1 uses JSON-LD format:
+
+```json
+{
+  "@context": "https://spdx.org/rdf/3.0.1/spdx-context.jsonld",
+  "@graph": [
+    {
+      "@type": "SpdxDocument",
+      "spdxId": "urn:example:doc",
+      "creationInfo": {
+        "@type": "CreationInfo",
+        "specVersion": "3.0.1",
+        "created": "2026-01-07T12:00:00Z",
+        "createdBy": ["urn:example:tool:stellaops"],
+        "profile": [
+          "https://spdx.org/rdf/3.0.1/terms/Core/ProfileIdentifierType/core",
+          "https://spdx.org/rdf/3.0.1/terms/Software/ProfileIdentifierType/software"
+        ]
+      },
+      "rootElement": ["urn:example:pkg:root"],
+      "element": [
+        "urn:example:pkg:root",
+        "urn:example:pkg:dep1"
+      ]
+    },
+    {
+      "@type": "software_Package",
+      "spdxId": "urn:example:pkg:root",
+      "name": "my-application",
+      "software_packageVersion": "2.0.0"
+    }
+  ]
+}
+```
+
+---
+
+## API Usage
+
+### Scanner SBOM Generation
+
+```http
+GET /api/v1/scan/{id}/sbom?format=spdx3&profile=software
+```
+
+**Parameters:**
+| Parameter | Values | Default |
+|-----------|--------|---------|
+| `format` | `spdx3`, `spdx2`, `cyclonedx` | `spdx2` |
+| `profile` | `software`, `lite` | `software` |
+
+### Attestor Build Profile
+
+```http
+GET /api/v1/attestation/{id}?format=spdx3
+```
+
+### VexLens Security Profile
+
+```http
+GET /api/v1/vex/consensus/{artifact}?format=spdx3
+```
+
+---
+
+## Profile Conformance
+
+Documents declare profile conformance in `CreationInfo.profile`:
+
+```json
+{
+  "profile": [
+    "https://spdx.org/rdf/3.0.1/terms/Core/ProfileIdentifierType/core",
+    "https://spdx.org/rdf/3.0.1/terms/Software/ProfileIdentifierType/software",
+    "https://spdx.org/rdf/3.0.1/terms/Security/ProfileIdentifierType/security"
+  ]
+}
+```
+
+StellaOps validates documents against declared profiles when:
+- Parsing external documents (opt-in validation)
+- Generating documents (automatic conformance)
+
+---
+
+## Migration from SPDX 2.x
+
+### Parallel Support
+
+During transition, StellaOps supports both formats:
+
+1. **SPDX 2.x** - Default for backward compatibility
+2. **SPDX 3.0.1** - Opt-in via `format=spdx3`
+
+### Key Differences
+
+| Aspect | SPDX 2.x | SPDX 3.0.1 |
+|--------|----------|------------|
+| Format | Flat JSON | JSON-LD |
+| Version field | `spdxVersion` | `specVersion` in CreationInfo |
+| Packages | `packages[]` array | `@graph` with `@type` |
+| Relationships | `relationships[]` | Relationship elements in `@graph` |
+| Checksums | `checksums[]` | `verifiedUsing` IntegrityMethod |
+| PURL | `externalRefs` | `externalIdentifier` |
+
+### Version Detection
+
+StellaOps auto-detects SPDX version:
+
+```csharp
+// 2.x: Has spdxVersion property
+if (root.TryGetProperty("spdxVersion", out _))
+    return SpdxVersion.V2;
+
+// 3.x: Has @context property
+if (root.TryGetProperty("@context", out _))
+    return SpdxVersion.V3;
+```
+
+---
+
+## Air-Gap Considerations
+
+For air-gapped deployments:
+
+1. **Bundle contexts locally** - SPDX JSON-LD contexts must be available offline
+2. **Configure local context URIs** - Point to local context files
+3. **Validate offline** - Use bundled schemas for validation
+
+```yaml
+# etc/spdx3.yaml
+Spdx3:
+  ContextResolution:
+    Mode: Local  # or Remote, Cached
+    LocalContextPath: /etc/stellaops/spdx3-contexts/
+```

+# Scheduler HLC Ordering Architecture
+
+This document describes the Hybrid Logical Clock (HLC) based ordering system used by the StellaOps Scheduler for audit-safe job queue operations.
+
+## Overview
+
+The Scheduler uses HLC timestamps instead of wall-clock time to ensure:
+
+1. **Total ordering** of jobs across distributed nodes
+2. **Audit-safe sequencing** with cryptographic chain linking
+3. **Deterministic merge** when offline nodes reconnect
+4. **Clock skew tolerance** in distributed deployments
+
+## HLC Timestamp Format
+
+An HLC timestamp consists of three components:
+
+```
+(PhysicalTime, LogicalCounter, NodeId)
+```
+
+| Component | Description | Example |
+|-----------|-------------|---------|
+| PhysicalTime | Unix milliseconds (UTC) | `1704585600000` |
+| LogicalCounter | Monotonic counter for same-millisecond events | `0`, `1`, `2`... |
+| NodeId | Unique identifier for the node | `scheduler-prod-01` |
+
+**String format:** `{physical}:{logical}:{nodeId}`
+Example: `1704585600000:0:scheduler-prod-01`
+
+## Database Schema

+    hasher.AppendData(Encoding.UTF8.GetBytes(action));
+    hasher.AppendData(Encoding.UTF8.GetBytes(prevChainLink ?? "genesis"));
+    hasher.AppendData(Encoding.UTF8.GetBytes(payloadDigest));
+    return Convert.ToHexString(hasher.GetHashAndReset()).ToLowerInvariant();
+}
+```
+
+## Configuration Options
+
+```yaml
+# etc/scheduler.yaml
+scheduler:
+  hlc:
+    enabled: true                    # Enable HLC ordering (default: true)
+    nodeId: "scheduler-prod-01"      # Unique node identifier
+    maxClockSkew: "00:00:05"         # Maximum tolerable clock skew (5 seconds)
+    persistenceInterval: "00:01:00"  # HLC state persistence interval
+    
+  chain:
+    enabled: true                    # Enable chain linking (default: true)
+    batchSize: 1000                  # Entries per batch snapshot
+    batchInterval: "00:05:00"        # Batch snapshot interval
+    signSnapshots: true              # DSSE-sign batch snapshots
+    keyId: "scheduler-signing-key"   # Key for snapshot signing
+```
+
+## Operational Considerations
+
+### Clock Skew Handling
+
+The HLC algorithm tolerates clock skew by:
+
+1. Advancing logical counter when physical time hasn't progressed
+2. Rejecting events with excessive clock skew (> `maxClockSkew`)
+3. Emitting `hlc_clock_skew_rejections_total` metric for monitoring
+
+**Alert:** `HlcClockSkewExceeded` triggers when skew > tolerance.
+
+### Chain Verification
+
+Verify chain integrity on startup and periodically:
+
+```bash
+# CLI command
+stella scheduler chain verify --tenant-id <tenant>
+
+# API endpoint
+GET /api/v1/scheduler/chain/verify?tenantId=<tenant>
+```
+
+### Offline Merge
+
+When offline nodes reconnect:
+
+1. Export local job log as bundle
+2. Import on connected node
+3. HLC-based merge produces deterministic ordering
+4. Chain is extended with merged entries
+
+See `docs/operations/airgap-operations-runbook.md` for details.
+
+## Metrics
+
+| Metric | Type | Description |
+|--------|------|-------------|
+| `hlc_ticks_total` | Counter | Total HLC tick operations |
+| `hlc_clock_skew_rejections_total` | Counter | Events rejected due to clock skew |
+| `hlc_physical_offset_seconds` | Gauge | Current physical time offset |
+| `scheduler_chain_entries_total` | Counter | Total chain log entries |
+| `scheduler_chain_verifications_total` | Counter | Chain verification operations |
+| `scheduler_chain_verification_failures_total` | Counter | Failed verifications |
+| `scheduler_batch_snapshots_total` | Counter | Batch snapshots created |

-# Telemetry Collector Deployment Guide
-
-> **Scope:** DevOps Guild, Observability Guild, and operators enabling the StellaOps telemetry pipeline (DEVOPS-OBS-50-001 / DEVOPS-OBS-50-003).
-
-This guide describes how to deploy the default OpenTelemetry Collector packaged with Stella Ops, validate its ingest endpoints, and prepare an offline-ready bundle for air-gapped environments.
-
----
-
-## 1. Overview
-
-The collector terminates OTLP traffic from Stella Ops services and exports metrics, traces, and logs.
-
-| Endpoint | Purpose | TLS | Authentication |
-| -------- | ------- | --- | -------------- |
-| `:4317`  | OTLP gRPC ingest | mTLS | Client certificate issued by collector CA |
-| `:4318`  | OTLP HTTP ingest | mTLS | Client certificate issued by collector CA |
-| `:9464`  | Prometheus scrape | mTLS | Same client certificate |
-| `:13133` | Health check | mTLS | Same client certificate |
-| `:1777`  | pprof diagnostics | mTLS | Same client certificate |
-
-The default configuration lives at `deploy/telemetry/otel-collector-config.yaml` and mirrors the Helm values in the `stellaops` chart.
-
----
-
-## 2. Local validation (Compose)
-
-```bash
-# 1. Generate dev certificates (CA + collector + client)
-./ops/devops/telemetry/generate_dev_tls.sh
-
-# 2. Start the collector overlay
-cd deploy/compose
-docker compose -f docker-compose.telemetry.yaml up -d
-
-# 3. Start the storage overlay (Prometheus, Tempo, Loki)
-docker compose -f docker-compose.telemetry-storage.yaml up -d
-
-# 4. Run the smoke test (OTLP HTTP)
-python ../../ops/devops/telemetry/smoke_otel_collector.py --host localhost
-```
-
-The smoke test posts sample traces, metrics, and logs and verifies that the collector increments the `otelcol_receiver_accepted_*` counters exposed via the Prometheus exporter. The storage overlay gives you a local Prometheus/Tempo/Loki stack to confirm end-to-end wiring. The same client certificate can be used by local services to weave traces together. See [`Telemetry Storage Deployment`](storage.md) for the storage configuration guidelines used in staging/production.
-
----
-
-## 3. Kubernetes deployment
-
-Enable the collector in Helm by setting the following values (example shown for the dev profile):
-
-```yaml
-telemetry:
-  collector:
-    enabled: true
-    defaultTenant: <tenant>
-    tls:
-      secretName: stellaops-otel-tls-<env>
-```
-
-Provide a Kubernetes secret named `stellaops-otel-tls-<env>` (for staging: `stellaops-otel-tls-stage`) with the keys `tls.crt`, `tls.key`, and `ca.crt`. The secret must contain the collector certificate, private key, and issuing CA respectively. Example:
-
-```bash
-kubectl create secret generic stellaops-otel-tls-stage \
-  --from-file=tls.crt=collector.crt \
-  --from-file=tls.key=collector.key \
-  --from-file=ca.crt=ca.crt
-```
-
-Helm renders the collector deployment, service, and config map automatically:
-
-```bash
-helm upgrade --install stellaops deploy/helm/stellaops -f deploy/helm/stellaops/values-dev.yaml
-```
-
-Update client workloads to trust `ca.crt` and present client certificates that chain back to the same CA.
-
----
-
-## 4. Offline packaging (DEVOPS-OBS-50-003)
-
-Use the packaging helper to produce a tarball that can be mirrored inside the Offline Kit or air-gapped sites:
-
-```bash
-python ops/devops/telemetry/package_offline_bundle.py --output out/telemetry/telemetry-bundle.tar.gz
-```
-
-The script gathers:
-
-- `deploy/telemetry/README.md`
-- Collector configuration (`deploy/telemetry/otel-collector-config.yaml` and Helm copy)
-- Helm template/values for the collector
-- Compose overlay (`deploy/compose/docker-compose.telemetry.yaml`)
-
-The tarball ships with a `.sha256` checksum. To attach a Cosign signature, add `--sign` and provide `COSIGN_KEY_REF`/`COSIGN_IDENTITY_TOKEN` env vars (or use the `--cosign-key` flag).
-
-Distribute the bundle alongside certificates generated by your PKI. For air-gapped installs, regenerate certificates inside the enclave and recreate the `stellaops-otel-tls` secret.
-
----
-
-## 5. Operational checks
-
-1. **Health probes** – `kubectl exec` into the collector pod and run `curl -fsSk --cert client.crt --key client.key --cacert ca.crt https://127.0.0.1:13133/healthz`.
-2. **Metrics scrape** – confirm Prometheus ingests `otelcol_receiver_accepted_*` counters.
-3. **Trace correlation** – ensure services propagate `trace_id` and `tenant.id` attributes; refer to `docs/modules/telemetry/guides/observability.md` for expected spans.
-4. **Certificate rotation** – when rotating the CA, update the secret and restart the collector; roll out new client certificates before enabling `require_client_certificate` if staged.

-## 4. Authority & tenancy integration
-
-1. Create Authority clients for each backend (`observability-prometheus`, `observability-loki`, `observability-tempo`).
-   ```bash
-   stella authority client create observability-prometheus \
-     --scopes obs:read \
-     --audience observability --description "Prometheus collector scrape"
-   stella authority client create observability-loki \
-     --scopes obs:logs timeline:read \
-     --audience observability --description "Loki ingestion"
-   stella authority client create observability-tempo \
-     --scopes obs:traces \
-     --audience observability --description "Tempo ingestion"
-   ```
-2. Mint tokens/credentials and store them in the secrets above (see staging bootstrap commands). Example:
-   ```bash
-   stella authority token issue observability-prometheus --ttl 30d > prometheus-stage.token
-   ```
-3. Update ingress/gateway policies to forward `X-StellaOps-Tenant` into Loki/Tempo so tenant headers propagate end-to-end, and ensure each workload sets `tenant.id` attributes (see `docs/observability/observability.md`).
-
----
-
-## 5. Retention & isolation
-
-- Adjust `deploy/telemetry/storage/tenants/*.yaml` to set per-tenant retention and ingestion limits.
-- Configure object storage (S3, GCS, Azure Blob) when moving beyond filesystem storage.
-- For air-gapped deployments, mirror the telemetry bundle using `ops/devops/telemetry/package_offline_bundle.py` and import inside the Offline Kit staging directory.

+kubectl -n observability create secret generic stellaops-otel-tls-stage \
+  --from-file=tls.crt=collector-stage.crt \
+  --from-file=tls.key=collector-stage.key \
+  --from-file=ca.crt=collector-ca.crt
+
+# Prometheus bearer token issued by Authority (scope obs:read)
+kubectl -n observability create secret generic stellaops-prometheus-token \
+  --from-file=token=prometheus-stage.token
+
+# Tenant overrides
+kubectl -n observability create configmap stellaops-loki-tenant-overrides \
+  --from-file=overrides.yaml=deploy/telemetry/storage/tenants/loki-overrides.yaml

+
+# Additional scrape config referencing the collector service
+kubectl -n observability create secret generic stellaops-prometheus-scrape \
+  --from-file=prometheus-additional.yaml=deploy/telemetry/storage/prometheus.yaml
+```
+
+Provision the following secrets/configs (names can be overridden via Helm values):
+
+| Name | Type | Notes |
+|------|------|-------|
+| `stellaops-otel-tls-stage` | Secret | Shared CA + server cert/key for collector/storage mTLS.
+| `stellaops-prometheus-token` | Secret | Bearer token minted by Authority (`obs:read`).
+| `stellaops-loki-tenant-overrides` | ConfigMap | Text from `deploy/telemetry/storage/tenants/loki-overrides.yaml`.
+| `tempo-tenant-overrides` | ConfigMap | Text from `deploy/telemetry/storage/tenants/tempo-overrides.yaml`.
+
+---
+
+## 4. Authority & tenancy integration
+
+1. Create Authority clients for each backend (`observability-prometheus`, `observability-loki`, `observability-tempo`).
+   ```bash
+   stella authority client create observability-prometheus \
+     --scopes obs:read \
+     --audience observability --description "Prometheus collector scrape"
+   stella authority client create observability-loki \
+     --scopes obs:logs timeline:read \
+     --audience observability --description "Loki ingestion"
+   stella authority client create observability-tempo \
+     --scopes obs:traces \
+     --audience observability --description "Tempo ingestion"
+   ```
+2. Mint tokens/credentials and store them in the secrets above (see staging bootstrap commands). Example:
+   ```bash
+   stella authority token issue observability-prometheus --ttl 30d > prometheus-stage.token
+   ```
+3. Update ingress/gateway policies to forward `X-StellaOps-Tenant` into Loki/Tempo so tenant headers propagate end-to-end, and ensure each workload sets `tenant.id` attributes (see `docs/observability/observability.md`).
+
+---
+
+## 5. Retention & isolation
+
+- Adjust `deploy/telemetry/storage/tenants/*.yaml` to set per-tenant retention and ingestion limits.
+- Configure object storage (S3, GCS, Azure Blob) when moving beyond filesystem storage.
+- For air-gapped deployments, mirror the telemetry bundle using `ops/devops/telemetry/package_offline_bundle.py` and import inside the Offline Kit staging directory.
+
+---
+
+## 6. Operational checklist
+
+- [ ] Certificates rotated and secrets updated.
 - [ ] Prometheus scrape succeeds (`curl -sk --cert client.crt --key client.key https://collector:9464`).
 - [ ] Tempo and Loki report tenant activity (`/api/status`).
 - [ ] Retention policy tested by uploading sample data and verifying expiry.
 - [ ] `python ops/devops/telemetry/validate_storage_stack.py` passes before committing updated configs.
 - [ ] Alerts wired into SLO evaluator (DEVOPS-OBS-51-001).
 - [ ] Component rule packs imported (e.g. `docs/modules/scheduler/operations/worker-prometheus-rules.yaml`).

+# Timeline Indexer
+
+> Timeline event indexing and query service.
+
+## Purpose
+
+TimelineIndexer provides fast, indexed access to timeline events across all StellaOps services. It enables efficient querying of vulnerability history, scan timelines, and policy evaluation trails.
+
+## Quick Links
+
+- [Architecture](./architecture.md) - Technical design and implementation details
+- [Guides](./guides/) - Query and configuration guides
+
+## Status
+
+| Attribute | Value |
+|-----------|-------|
+| **Maturity** | Production |
+| **Last Reviewed** | 2025-12-29 |
+| **Maintainer** | Platform Guild |
+
+## Key Features
+
+- **Event Indexing**: Index events from multiple StellaOps services
+- **Time-Range Queries**: Efficient time-series queries with filtering
+- **Event Stream Integration**: Consume from NATS/Valkey event streams
+- **PostgreSQL Storage**: Time-series indexes for fast retrieval
+
+## Dependencies
+
+### Upstream (this module depends on)
+- **PostgreSQL** - Event storage with time-series indexes
+- **NATS/Valkey** - Event stream consumption
+- **Authority** - Authentication
+
+### Downstream (modules that depend on this)
+- **Web Console** - Timeline visualization
+- **CLI** - Timeline queries
+- **ExportCenter** - Timeline data exports
+
+## Configuration
+
+```yaml
+timeline_indexer:
+  event_sources:
+    - nats://events.stellaops.local
+  retention_days: 365
+```
+
+## Notes
+
+TimelineIndexer indexes events; it does not generate them. Events are received from event streams published by other services.

-# Zastava Runtime Operations Runbook
-
-This runbook covers the runtime plane (Observer DaemonSet + Admission Webhook).
-It aligns with `Sprint 12 – Runtime Guardrails` and assumes components consume
-`StellaOps.Zastava.Core` (`AddZastavaRuntimeCore(...)`).
-
-## 1. Prerequisites
-
-- **Authority client credentials** – service principal `zastava-runtime` with scopes
-  `aud:scanner` and `api:scanner.runtime.write`. Provision DPoP keys and mTLS client
-  certs before rollout.
-- **Scanner/WebService reachability** – cluster DNS entry (e.g. `scanner.internal`)
-  resolvable from every node running Observer/Webhook.
-- **Host mounts** – read-only access to `/proc`, container runtime state
-  (`/var/lib/containerd`, `/var/run/containerd/containerd.sock`) and scratch space
-  (`/var/run/zastava`).
-- **Offline kit bundle** – operators staging air-gapped installs must download
-  `offline-kit/zastava-runtime-{version}.tar.zst` containing container images,
-  Grafana dashboards, and Prometheus rules referenced below.
-- **Secrets** – Authority OpTok cache dir, DPoP private keys, and webhook TLS secrets
-  live outside git. For air-gapped installs copy them to the sealed secrets vault.
-
-### 1.1 Telemetry quick reference
-
-| Metric | Description | Notes |
-|--------|-------------|-------|
-| `zastava.runtime.events.total{tenant,component,kind}` | Rate of observer events sent to Scanner | Expect >0 on busy nodes. |
-| `zastava.runtime.backend.latency.ms` | Histogram (ms) for `/runtime/events` and `/policy/runtime` calls | P95 & P99 drive alerting. |
-| `zastava.admission.decisions.total{decision}` | Admission verdict counts | Track deny spikes or fail-open fallbacks. |
-| `zastava.admission.cache.hits.total` | (future) Cache utilisation once Observer batches land | Placeholder until Observer tasks 12-004 complete. |
-
-## 2. Deployment workflows
-
-### 2.1 Fresh install (Helm overlay)
-
-1. Load offline kit bundle: `oras cp offline-kit/zastava-runtime-*.tar.zst oci:registry.internal/zastava`.
-2. Render values:
-   - `zastava.runtime.tenant`, `environment`, `deployment` (cluster identifier).
-   - `zastava.runtime.authority` block (issuer, clientId, audience, DPoP toggle).
-   - `zastava.runtime.metrics.commonTags.cluster` for Prometheus labels.
-3. Pre-create secrets:
-   - `zastava-authority-dpop` (JWK + private key).
-   - `zastava-authority-mtls` (client cert/key chain).
-   - `zastava-webhook-tls` (serving cert; CSR bundle if using auto-approval).
-4. Deploy Observer DaemonSet and Webhook chart:
-   ```sh
-   helm upgrade --install zastava-runtime deploy/helm/zastava \
-     -f values/zastava-runtime.yaml \
-     --namespace stellaops \
-     --create-namespace
-   ```
-5. Verify:
-   - `kubectl -n stellaops get pods -l app=zastava-observer` ready.
-   - `kubectl -n stellaops logs ds/zastava-observer --tail=20` shows
-     `Issued runtime OpTok` audit line with DPoP token type.
-   - Admission webhook registered: `kubectl get validatingwebhookconfiguration zastava-webhook`.
-
-### 2.2 Upgrades
-
-1. Scale webhook deployment to `--replicas=3` (rolling).
-2. Drain one node per AZ to ensure Observer tolerates disruption.
-3. Apply chart upgrade; watch `zastava.runtime.backend.latency.ms` P95 (<250 ms).
-4. Post-upgrade, run smoke tests:
-   - Apply unsigned Pod manifest → expect `deny` (policy fail).
-   - Apply signed Pod manifest → expect `allow`.
-5. Record upgrade in ops log with Git SHA + Helm chart version.
-
-### 2.3 Rollback
-
-1. Use Helm revision history: `helm history zastava-runtime`.
-2. Rollback: `helm rollback zastava-runtime <revision>`.
-3. Invalidate cached OpToks:
-   ```sh
-   kubectl -n stellaops exec deploy/zastava-webhook -- \
-     zastava-webhook invalidate-op-token --audience scanner
-   ```
-4. Confirm observers reconnect via metrics (`rate(zastava_runtime_events_total[5m])`).
-
-## 3. Authority & security guardrails
-
-- Tokens must be `DPoP` type when `requireDpop=true`. Logs emit
-  `authority.token.issue` scope with decision data; absence indicates misconfig.
-- `requireMutualTls=true` enforces mTLS during token acquisition. Disable only in
-  lab clusters; expect warning log `Mutual TLS requirement disabled`.
-- Static fallback tokens (`allowStaticTokenFallback=true`) should exist only during
-  initial bootstrap. Rotate nightly; preference is to disable once Authority reachable.
-- Audit every change in `zastava.runtime.authority` through change management.
-  Use `kubectl get secret zastava-authority-dpop -o jsonpath='{.metadata.annotations.revision}'`
-  to confirm key rotation.
-
-## 4. Incident response
-
-### 4.1 Authority offline
-
-1. Check Prometheus alert `ZastavaAuthorityTokenStale`.
-2. Inspect Observer logs for `authority.token.fallback` scope.
-3. If fallback engaged, verify static token validity duration; rotate secret if older than 24 h.
-4. Once Authority restored, delete static fallback secret and restart pods to rebind DPoP keys.
-
-### 4.2 Scanner/WebService latency spike
-
-1. Alert `ZastavaRuntimeBackendLatencyHigh` fires at P95 > 750 ms for 5 minutes.
-2. Run backend health: `kubectl -n scanner exec deploy/scanner-web -- curl -f localhost:8080/healthz/ready`.
-3. If backend degraded, auto buffer may throttle. Confirm disk-backed queue size via
-   `kubectl logs ds/zastava-observer | grep buffer.drops`.
-4. Consider enabling fail-open for namespaces listed in runbook Appendix B (temporary).
-
-### 4.3 Admission deny storm
-
-1. Alert `ZastavaAdmissionDenySpike` indicates >20 denies/minute.
-2. Pull sample: `kubectl logs deploy/zastava-webhook --since=10m | jq '.decision'`.
-3. Cross-check policy backlog in Scanner (`/policy/runtime` logs). Engage application
-   owner; optionally set namespace to `failOpenNamespaces` after risk assessment.

-Runtime events emitted by Observer now include `process.buildId` (from the ELF
-`NT_GNU_BUILD_ID` note) and Scanner `/policy/runtime` surfaces the most recent
-`buildIds` list per digest. Operators can use these hashes to locate debug
-artifacts during incident response:
-
-1. Capture the hash from CLI/webhook/Scanner API—for example:
-   ```bash
-   stellaops-cli runtime policy test --image <digest> --namespace <ns>
-   ```
-   Copy one of the `Build IDs` (e.g.
-   `5f0c7c3cb4d9f8a4f1c1d5c6b7e8f90123456789`).
-2. Derive the debug path (`<aa>/<rest>` under `.build-id`) and check it exists:
-   ```bash
-   ls /var/opt/debug/.build-id/5f/0c7c3cb4d9f8a4f1c1d5c6b7e8f90123456789.debug
-   ```
-3. If the file is missing, rehydrate it from Offline Kit bundles or the
-   `debug-store` object bucket (mirror of release artefacts):
-   ```bash
-   oras cp oci://registry.internal/debug-store:latest . --include \
-     "5f/0c7c3cb4d9f8a4f1c1d5c6b7e8f90123456789.debug"
-   ```
-4. Confirm the running process advertises the same GNU build-id before
-   symbolising:
-   ```bash
-   readelf -n /proc/$(pgrep -f payments-api | head -n1)/exe | grep -i 'Build ID'
-   ```
-5. Attach the `.debug` file in `gdb`/`lldb`, feed it to `eu-unstrip`, or cache it
-   in `debuginfod` for fleet-wide symbol resolution:
-   ```bash
-   debuginfod-find debuginfo 5f0c7c3cb4d9f8a4f1c1d5c6b7e8f90123456789 >/tmp/payments-api.debug

-6. For musl-based images, expect shorter build-id footprints. Missing hashes in
-   runtime events indicate stripped binaries without the GNU note—schedule a
-   rebuild with `-Wl,--build-id` enabled or add the binary to the debug-store
-   allowlist so the scanner can surface a fallback symbol package.
-
-Monitor `scanner.policy.runtime` responses for the `buildIds` field; absence of

+## Appendix D: HLC-Based Job Synchronization
+
+> **Sprint**: SPRINT_20260105_002_003_ROUTER  
+> **Added**: 2026-01-07
+
+### Overview
+
+When running in air-gap mode, scheduled jobs are queued locally using Hybrid Logical Clocks (HLC). Upon reconnection or physical transfer, these jobs can be merged deterministically with the central scheduler while preserving global ordering.
+
+### Key Concepts
+
+| Term | Description |
+|------|-------------|
+| **HLC Timestamp** | Tuple of (PhysicalTime, LogicalCounter, NodeId) for total ordering |
+| **Job Log** | Append-only log of jobs enqueued while offline |
+| **Chain Link** | Cryptographic hash linking each job to its predecessor |
+| **Air-Gap Bundle** | Exportable package containing job logs from one or more offline nodes |
+
+### Exporting Jobs from Offline Node
+
+```bash
+# Export all pending jobs to a bundle
+stella airgap export \
+  --output /media/usb/jobs-bundle.json \
+  --tenant <tenant-id>
+
+# Export with DSSE signature (requires signing key)
+stella airgap export \
+  --output /media/usb/jobs-bundle.json \
+  --tenant <tenant-id> \
+  --sign
+```
+
+### Importing Jobs to Central Scheduler
+
+```bash
+# Import bundle and merge jobs
+stella airgap import \
+  --bundle /media/usb/jobs-bundle.json
+
+# Import with signature verification
+stella airgap import \
+  --bundle /media/usb/jobs-bundle.json \
+  --verify-signature
+
+# Dry-run to preview merge results
+stella airgap import \
+  --bundle /media/usb/jobs-bundle.json \
+  --dry-run
+```
+
+### Merge Behavior
+
+1. **Total Ordering**: Jobs are merged by HLC order key (PhysicalTime, LogicalCounter, NodeId, JobId)
+2. **Duplicate Detection**: Jobs with the same JobId are deduplicated
+3. **Chain Verification**: Each job's chain link is verified against its predecessor
+4. **Conflict Resolution**: Same-payload jobs from different nodes are kept; conflicting payloads are flagged
+
+### Monitoring Metrics
+
+| Metric | Description |
+|--------|-------------|
+| `airgap_bundles_exported_total` | Total bundles exported |
+| `airgap_bundles_imported_total` | Total bundles imported |
+| `airgap_jobs_synced_total` | Total jobs synchronized |
+| `airgap_merge_conflicts_total` | Merge conflicts by type |
+| `airgap_sync_duration_seconds` | Sync operation duration |
+
+### Troubleshooting
+
+**Bundle signature verification fails**
+1. Check that signing key is correctly configured
+2. Verify bundle was not modified during transfer
+3. Check key ID matches expected signer
+
+**Merge conflicts detected**
+1. Review conflicts in import output
+2. Check for clock skew between offline nodes
+3. Use `--conflict-strategy` flag to auto-resolve
+
+**Jobs missing after import**
+1. Check for duplicate JobIds (same job, same node)
+2. Verify chain integrity with `stella airgap verify --bundle <path>`
+3. Review import logs for skipped entries

-# Stella Ops Deployment Upgrade & Rollback Runbook
-
-_Last updated: 2025-10-26 (Sprint 14 – DEVOPS-OPS-14-003)._
-
-This runbook describes how to promote a new release across the supported deployment profiles (Helm and Docker Compose), how to roll back safely, and how to keep channels (`edge`, `stable`, `airgap`) aligned. All steps assume you are working from a clean checkout of the release branch/tag.
-
----
-
-## 1. Channel overview
-
-| Channel | Release manifest | Helm values | Compose profile |
-|---------|------------------|-------------|-----------------|
-| `edge`  | `deploy/releases/2025.10-edge.yaml` | `deploy/helm/stellaops/values-dev.yaml` | `deploy/compose/docker-compose.dev.yaml` |
-| `stable` | `deploy/releases/2025.09-stable.yaml` | `deploy/helm/stellaops/values-stage.yaml`, `deploy/helm/stellaops/values-prod.yaml` | `deploy/compose/docker-compose.stage.yaml`, `deploy/compose/docker-compose.prod.yaml` |
-| `airgap` | `deploy/releases/2025.09-airgap.yaml` | `deploy/helm/stellaops/values-airgap.yaml` | `deploy/compose/docker-compose.airgap.yaml` |
-
-Infrastructure components (PostgreSQL, Valkey, MinIO, RustFS) are pinned in the release manifests and inherited by the deployment profiles. Supporting dependencies such as `nats` remain on upstream LTS tags; review `deploy/compose/*.yaml` for the authoritative set.
-
----
-
-## 2. Pre-flight checklist
-
-1. **Refresh release manifest**  
-   Pull the latest manifest for the channel you are promoting (`deploy/releases/<version>-<channel>.yaml`).
-
-2. **Align deployment bundles with the manifest**  
-   Run the alignment checker for every profile that should pick up the release. Pass `--ignore-repo nats` to skip auxiliary services.
-   ```bash
-   ./deploy/tools/check-channel-alignment.py \
-       --release deploy/releases/2025.10-edge.yaml \
-       --target deploy/helm/stellaops/values-dev.yaml \
-       --target deploy/compose/docker-compose.dev.yaml \
-       --ignore-repo nats
-   ```
-   Repeat for other channels (`stable`, `airgap`), substituting the manifest and target files.
-
-3. **Lint and template profiles**
-   ```bash
-   ./deploy/tools/validate-profiles.sh
-   ```
-
-4. **Smoke the Offline Kit debug store (edge/stable only)**  
-   When the release pipeline has generated `out/release/debug/.build-id/**`, mirror the assets into the Offline Kit staging tree:
-   ```bash
-  ./ops/offline-kit/mirror_debug_store.py \
-       --release-dir out/release \
-       --offline-kit-dir out/offline-kit
-   ```
-   Archive the resulting `out/offline-kit/metadata/debug-store.json` alongside the kit bundle.
-
-5. **Review compatibility matrix**
-   Confirm PostgreSQL, Valkey, and RustFS versions in the release manifest match platform SLOs. The default targets are `postgres:16-alpine`, `valkey:8.0`, `rustfs:2025.10.0-edge`.
-
-6. **Create a rollback bookmark**  
-   Record the current Helm revision (`helm history stellaops -n stellaops`) and compose tag (`git describe --tags`) before applying changes.
-
----
-
-## 3. Helm upgrade procedure (staging → production)
-
-1. Switch to the deployment branch and ensure secrets/config maps are current.
-2. Apply the upgrade in the staging cluster:
-   ```bash
-   helm upgrade stellaops deploy/helm/stellaops \
-     -f deploy/helm/stellaops/values-stage.yaml \
-     --namespace stellaops \
-     --atomic \
-     --timeout 15m
-   ```
-3. Run smoke tests (`scripts/smoke-tests.sh` or environment-specific checks).
-4. Promote to production using the prod values file and the same command.
-5. Record the new revision number and Git SHA in the change log.
-
-### Rollback (Helm)
-
-1. Identify the previous revision: `helm history stellaops -n stellaops`.
-2. Execute:
-   ```bash
-   helm rollback stellaops <revision> \
-     --namespace stellaops \
-     --wait \
-     --timeout 10m
-   ```
-3. Verify `kubectl get pods` returns healthy workloads; rerun smoke tests.
-4. Update the incident/operations log with root cause and rollback details.
-
----
-
-## 4. Docker Compose upgrade procedure
-
-1. Update environment files (`deploy/compose/env/*.env.example`) with any new settings and sync secrets to hosts.
-2. Pull the tagged repository state corresponding to the release (e.g. `git checkout 2025.09.2` for stable).
-3. Apply the upgrade:
-   ```bash
-   docker compose \
-     --env-file deploy/compose/env/prod.env \
-     -f deploy/compose/docker-compose.prod.yaml \
-     pull
-
-   docker compose \
-     --env-file deploy/compose/env/prod.env \
-     -f deploy/compose/docker-compose.prod.yaml \
-     up -d
-   ```
-4. Tail logs for critical services (`docker compose logs -f authority concelier`).
-5. Update monitoring dashboards/alerts to confirm normal operation.
-
-### Rollback (Compose)
-
-1. Check out the previous release tag (e.g. `git checkout 2025.09.1`).
-2. Re-run `docker compose pull` and `docker compose up -d` with that profile. Docker will restore the prior digests.
-3. If reverting to a known-good snapshot is required, restore volume backups (see `docs/modules/authority/operations/backup-restore.md` and associated service guides).
-4. Log the rollback in the operations journal.
-
----
-
-## 5. Channel promotion workflow
-
-1. Author or update the channel manifest under `deploy/releases/`.
-2. Mirror the new digests into Helm/Compose values and run the alignment script for each profile.
-3. Commit the changes with a message that references the release version and channel (e.g. `deploy: promote 2025.10.0-edge`).
-4. Publish release notes and update `deploy/releases/README.md` (if applicable).
-5. Tag the repository when promoting stable or airgap builds.
-
----
-
-## 6. Upgrade rehearsal & rollback drill log
-
-Maintain rehearsal notes in `docs/modules/devops/runbooks/launch-cutover.md` or the relevant sprint planning document. After each drill capture:
-
-- Release version tested
-- Date/time
-- Participants
-- Issues encountered & fixes
-- Rollback duration (if executed)
-
-Attach the log to the sprint retro or operational wiki.
-
-| Date (UTC) | Channel | Outcome | Notes |
-|------------|---------|---------|-------|
-| 2025-10-26 | Documentation dry-run | Planned | Runbook refreshed; next live drill scheduled for 2025-11 edge → stable promotion.

+   Repeat for other channels (`stable`, `airgap`), substituting the manifest and target files.
+
+3. **Lint and template profiles**
+   ```bash
+   ./deploy/tools/validate-profiles.sh
+   ```
+
+4. **Smoke the Offline Kit debug store (edge/stable only)**  
+   When the release pipeline has generated `out/release/debug/.build-id/**`, mirror the assets into the Offline Kit staging tree:
+   ```bash
+  ./ops/offline-kit/mirror_debug_store.py \
+       --release-dir out/release \
+       --offline-kit-dir out/offline-kit
+   ```
+   Archive the resulting `out/offline-kit/metadata/debug-store.json` alongside the kit bundle.
+
+5. **Review compatibility matrix**
+   Confirm PostgreSQL, Valkey, and RustFS versions in the release manifest match platform SLOs. The default targets are `postgres:16-alpine`, `valkey:8.0`, `rustfs:2025.10.0-edge`.
+
+6. **Create a rollback bookmark**  
+   Record the current Helm revision (`helm history stellaops -n stellaops`) and compose tag (`git describe --tags`) before applying changes.
+
+---
+
+## 3. Helm upgrade procedure (staging → production)
+
+1. Switch to the deployment branch and ensure secrets/config maps are current.
+2. Apply the upgrade in the staging cluster:
+   ```bash
+   helm upgrade stellaops devops/helm/stellaops \
+     -f devops/helm/stellaops/values-stage.yaml \
+     --namespace stellaops \
+     --atomic \
+     --timeout 15m
+   ```
+3. Run smoke tests (`scripts/smoke-tests.sh` or environment-specific checks).
+4. Promote to production using the prod values file and the same command.
+5. Record the new revision number and Git SHA in the change log.
+
+### Rollback (Helm)
+
+1. Identify the previous revision: `helm history stellaops -n stellaops`.
+2. Execute:
+   ```bash
+   helm rollback stellaops <revision> \
+     --namespace stellaops \
+     --wait \
+     --timeout 10m
+   ```
+3. Verify `kubectl get pods` returns healthy workloads; rerun smoke tests.
+4. Update the incident/operations log with root cause and rollback details.
+
+---
+
+## 4. Docker Compose upgrade procedure
+
+1. Update environment files (`devops/compose/env/*.env.example`) with any new settings and sync secrets to hosts.
+2. Pull the tagged repository state corresponding to the release (e.g. `git checkout 2025.09.2` for stable).
+3. Apply the upgrade:
+   ```bash
+   docker compose \
+     --env-file devops/compose/env/prod.env \
+     -f devops/compose/docker-compose.prod.yaml \
+     pull
+
+   docker compose \
+     --env-file devops/compose/env/prod.env \
+     -f devops/compose/docker-compose.prod.yaml \
+     up -d
+   ```
+4. Tail logs for critical services (`docker compose logs -f authority concelier`).
+5. Update monitoring dashboards/alerts to confirm normal operation.
+
+### Rollback (Compose)
+
+1. Check out the previous release tag (e.g. `git checkout 2025.09.1`).
+2. Re-run `docker compose pull` and `docker compose up -d` with that profile. Docker will restore the prior digests.
+3. If reverting to a known-good snapshot is required, restore volume backups (see `docs/modules/authority/operations/backup-restore.md` and associated service guides).
+4. Log the rollback in the operations journal.
+
+---
+
+## 5. Channel promotion workflow
+
+1. Author or update the channel manifest under `deploy/releases/`.
+2. Mirror the new digests into Helm/Compose values and run the alignment script for each profile.
+3. Commit the changes with a message that references the release version and channel (e.g. `deploy: promote 2025.10.0-edge`).
+4. Publish release notes and update `deploy/releases/README.md` (if applicable).
+5. Tag the repository when promoting stable or airgap builds.
+
+---
+
+## 6. Upgrade rehearsal & rollback drill log
+
+Maintain rehearsal notes in `docs/modules/devops/runbooks/launch-cutover.md` or the relevant sprint planning document. After each drill capture:
+
+- Release version tested
+- Date/time
+- Participants
+- Issues encountered & fixes
+- Rollback duration (if executed)
+
+Attach the log to the sprint retro or operational wiki.
+
+| Date (UTC) | Channel | Outcome | Notes |
+|------------|---------|---------|-------|
+| 2025-10-26 | Documentation dry-run | Planned | Runbook refreshed; next live drill scheduled for 2025-11 edge → stable promotion.

-## 3. Rehearsal (Staging) Checklist
-
-1. `docker network create stellaops_frontdoor || true` (if not present on staging jump host).
-2. Run `deploy/tools/validate-profiles.sh` and archive output.
-3. Apply staging secrets (`kubectl apply -f secrets/stage/*.yaml` or `helm secrets upgrade`) ensuring `stellaops-stage` credentials align with `values-stage.yaml`.
-4. Perform `helm upgrade stellaops deploy/helm/stellaops -f deploy/helm/stellaops/values-stage.yaml` in staging cluster.
-5. Verify health endpoints: `curl https://authority.stage.../healthz`, `curl https://scanner.stage.../healthz`.
-6. Execute smoke CLI: `stellaops-cli scan submit --profile staging --sbom samples/sbom/demo.json` and confirm report status in UI.
-7. Document total wall time and any deviations in the rehearsal log.
-
-Rehearsal must complete without manual interventions before proceeding to production.
-
-## 4. Production Cutover Steps
-
-### 4.1 Pre-flight
-- Confirm production secrets in the appropriate secret store (`stellaops-prod-core`, `stellaops-prod-mongo`, `stellaops-prod-minio`, `stellaops-prod-notify`) contain the keys referenced in `values-prod.yaml`.
-- Ensure the external reverse proxy network exists: `docker network create stellaops_frontdoor || true` on each compose host.
-- Back up current configuration and data:
-  - Mongo snapshot: `mongodump --uri "$MONGO_BACKUP_URI" --out /backups/launch-$(date -Iseconds)`.
-  - MinIO policy export: `mc mirror --overwrite minio/stellaops minio-backup/stellaops-$(date +%Y%m%d%H%M)`.
-
-### 4.2 Apply Updates (Compose)
-1. On each compose node, pull updated images for release `2025.09.2`:
-   ```bash
-   docker compose --env-file prod.env -f deploy/compose/docker-compose.prod.yaml pull
-   ```
-2. Deploy changes:
-   ```bash
-   docker compose --env-file prod.env -f deploy/compose/docker-compose.prod.yaml up -d
-   ```
-3. Confirm containers healthy via `docker compose ps` and `docker logs <service> --tail 50`.
-
-### 4.3 Apply Updates (Helm/Kubernetes)
-If using Kubernetes, perform:
-```bash
-helm upgrade stellaops deploy/helm/stellaops -f deploy/helm/stellaops/values-prod.yaml --atomic --timeout 15m
-```
-Monitor rollout with `kubectl get pods -n stellaops --watch` and `kubectl rollout status deployment/<service>`.
-
-### 4.4 Configuration Validation
-- Verify Authority issuer metadata: `curl https://authority.prod.../.well-known/openid-configuration`.
-- Validate Signer DSSE endpoint: `stellaops-cli signer verify --base-url https://signer.prod... --bundle samples/dsse/demo.json`.
-- Check Scanner queue connectivity: `docker exec stellaops-scanner-web dotnet StellaOps.Scanner.WebService.dll health queue` (returns success).
-- Ensure Notify (legacy) still accessible while Notifier migration pending.
-
-## 5. Smoke Tests
-
-| Test | Command / Action | Expected Result |
-| --- | --- | --- |
-| API health | `curl https://scanner.prod.../healthz` | HTTP 200 with `status":"Healthy"` |
-| Scan submit | `stellaops-cli scan submit --profile prod --sbom samples/sbom/demo.json` | Scan completes < 5 minutes; report accessible with signed DSSE |
-| Runtime event ingest | Post sample event from Zastava observer fixture | `/runtime/events` responds 202 Accepted; record visible in Mongo `runtime_events` |
-| Signing | `stellaops-cli signer sign --bundle demo.json` | Returns DSSE with matching SHA256 and signer metadata |
-| Attestor verify | `stellaops-cli attestor verify --uuid <uuid>` | Verification result `ok=true` |
-| Web UI | Manual login, verify dashboards render and latency within budget | UI loads under 2 seconds; policy views consistent |
-
-Log results in the change ticket with timestamps and screenshots where applicable.
-
-## 6. Rollback Procedure
-
-1. Assess failure scope; if systemic, initiate rollback immediately while preserving logs/artifacts.
-2. For Compose:
-   ```bash
-   docker compose --env-file prod.env -f deploy/compose/docker-compose.prod.yaml down
-   docker compose --env-file stage.env -f deploy/compose/docker-compose.stage.yaml up -d
-   ```
-3. For Helm:
-   ```bash
-   helm rollback stellaops <previous-release-number> --namespace stellaops
-   ```
-4. Restore Mongo snapshot if data inconsistency detected: `mongorestore --uri "$MONGO_BACKUP_URI" --drop /backups/launch-<timestamp>`.
-5. Restore MinIO mirror if required: `mc mirror minio-backup/stellaops-<timestamp> minio/stellaops`.
-6. Notify stakeholders of rollback and capture root cause notes in incident ticket.
-
-## 7. Post-cutover Actions
-
-- Keep heightened monitoring for 4 hours post cutover; track latency, error rates, and queue depth.
-- Confirm audit trails: Authority tokens issued, Scanner events recorded, Attestor submissions stored.
-- Update `docs/modules/devops/runbooks/launch-readiness.md` if any new gaps or follow-ups discovered.
-- Schedule retrospective within 48 hours; include DevOps, module guilds, and product owner.

-## 2. Deployment Readiness Checklist
-
-- **Production profiles committed:** `deploy/compose/docker-compose.prod.yaml` and `deploy/helm/stellaops/values-prod.yaml` added with front-door network hand-off and secret references for Mongo/MinIO/core services.
-- **Secrets placeholders documented:** `deploy/compose/env/prod.env.example` enumerates required credentials (`MONGO_INITDB_ROOT_PASSWORD`, `MINIO_ROOT_PASSWORD`, Redis/NATS endpoints, `FRONTDOOR_NETWORK`). Helm values reference Kubernetes secrets (`stellaops-prod-core`, `stellaops-prod-mongo`, `stellaops-prod-minio`, `stellaops-prod-notify`).

+# Facet Quota Configuration Guide
+
+> **Version**: 1.0.0  
+> **Sprint**: SPRINT_20260105_002_003_FACET  
+> **Last Updated**: 2026-01-07
+
+This guide covers configuration and operation of per-facet drift quotas in StellaOps.
+
+---
+
+## Overview
+
+Facet quotas control how much change is acceptable in different parts of a container image between builds. When drift exceeds a quota, StellaOps can:
+
+- **Warn**: Log and report the drift, continue processing
+- **Block**: Fail the policy gate, prevent deployment
+- **Auto-VEX**: Generate a VEX draft for human review
+
+### What are Facets?
+
+Facets are logical groupings of files in a container image:
+
+| Facet | Description | Typical Files |
+|-------|-------------|---------------|
+| `binaries` | Executables and libraries | `*.so`, `*.dll`, ELF files |
+| `lang-deps` | Language package dependencies | `node_modules/`, `site-packages/`, `.m2/` |
+| `os-packages` | OS-level packages | RPM, DEB, APK metadata |
+| `configs` | Configuration files | `*.conf`, `*.yaml`, `*.json` |
+| `data` | Static data files | Images, fonts, templates |
+
+### Why Per-Facet Quotas?
+
+Different file types have different risk profiles:
+
+- A single binary change might be intentional (rebuild) or might indicate compromise
+- 100 new npm packages might be a normal dependency update
+- Removing OS security packages is always suspicious
+
+Per-facet quotas let you apply appropriate controls to each category.
+
+---
+
+## Configuration
+
+### File Location
+
+```
+/etc/stellaops/facet-quotas.yaml
+```
+
+Or via environment variable:
+```bash
+STELLAOPS_FACET_QUOTAS_PATH=/path/to/facet-quotas.yaml
+```
+
+### Basic Structure
+
+```yaml
+# Default quota for all facets
+defaults:
+  maxChurnPercent: 30       # Max % of files that can change
+  maxChangedFiles: 100      # Max absolute changed files
+  maxAddedFiles: 50         # Max new files
+  maxRemovedFiles: 50       # Max removed files
+  action: warn              # warn | block | auto-vex
+
+# Per-facet overrides
+facets:
+  binaries:
+    maxChurnPercent: 10
+    action: block
+  lang-deps:
+    maxChurnPercent: 40
+    action: auto-vex
+```
+
+### Quota Parameters
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `maxChurnPercent` | decimal | Maximum percentage of files in the facet that can change |
+| `maxChangedFiles` | int | Maximum absolute number of changed files |
+| `maxAddedFiles` | int | Maximum number of new files (optional) |
+| `maxRemovedFiles` | int | Maximum number of removed files (optional) |
+| `action` | string | Action when quota exceeded: `warn`, `block`, `auto-vex` |
+| `allowlist` | list | Glob patterns to exclude from quota calculation |
+
+### Using Profiles
+
+StellaOps includes predefined quota profiles:
+
+```yaml
+# Use a predefined profile
+profile: moderate  # strict | moderate | permissive
+
+# Optionally override specific facets
+facets:
+  binaries:
+    action: block  # Override from profile
+```
+
+| Profile | Description | Use Case |
+|---------|-------------|----------|
+| `strict` | Minimal tolerance, blocks most drift | Production, regulated |
+| `moderate` | Balanced, auto-VEX for review | Staging, pre-prod |
+| `permissive` | Relaxed, warnings only | Development |
+
+---
+
+## Policy Integration
+
+### Enabling Quota Gates
+
+In your policy configuration:
+
+```yaml
+# policy-gates.yaml
+gates:
+  - name: facet-quota
+    enabled: true
+    options:
+      configPath: /etc/stellaops/facet-quotas.yaml
+      failOnMissingSeal: true  # Fail if no baseline seal exists
+```
+
+### Seal Management
+
+Quotas compare current state against a "sealed" baseline:
+
+```bash
+# Seal current image as baseline
+stella facet seal --image myapp:v1.2.3 --tenant production
+
+# List seals
+stella facet seals list --tenant production
+
+# Compare against seal
+stella facet drift --image myapp:v1.2.4 --baseline v1.2.3
+```
+
+---
+
+## Auto-VEX Workflow
+
+When quota action is `auto-vex`, StellaOps:
+
+1. Generates a VEX draft with drift justification
+2. Queues the draft for human review
+3. Sends notifications to configured channels
+
+### VEX Draft Structure
+
+```json
+{
+  "statements": [{
+    "vulnerability": "FACET-DRIFT-2026-001234",
+    "status": "under_investigation",
+    "justification": "facet_drift_detected",
+    "impact_statement": "Drift in 'binaries' facet: 15% churn (quota: 10%), 12 files changed"
+  }]
+}
+```
+
+### Approving VEX Drafts
+
+```bash
+# List pending drafts
+stella vex drafts list --status pending
+
+# Approve a draft
+stella vex draft approve --id <draft-id> --reason "Expected rebuild"
+
+# Reject a draft
+stella vex draft reject --id <draft-id> --reason "Unexpected changes"
+```
+
+---
+
+## Monitoring
+
+### Metrics
+
+| Metric | Description |
+|--------|-------------|
+| `facet_drift_evaluations_total` | Total drift evaluations |
+| `facet_quota_exceeded_total` | Quota breaches by facet and action |
+| `facet_vex_drafts_created_total` | Auto-VEX drafts generated |
+| `facet_seal_operations_total` | Seal create/update operations |
+
+### Grafana Dashboard
+
+Import the facet quota dashboard:
+```
+devops/observability/grafana/facet-quota-metrics.json
+```
+
+### Alerts
+
+Key alerts to configure:
+
+- `FacetQuotaBlockRate`: High rate of blocked builds
+- `FacetDriftAnomalous`: Unusual drift patterns
+- `FacetVexDraftBacklog`: Growing VEX draft queue
+
+---
+
+## Troubleshooting
+
+### Quota Unexpectedly Blocking
+
+1. Check current quota configuration:
+   ```bash
+   stella facet quota show --facet binaries
+   ```
+
+2. Review drift details:
+   ```bash
+   stella facet drift --image myapp:latest --verbose
+   ```
+
+3. Check allowlist patterns:
+   ```bash
+   stella facet quota test-allowlist --pattern "**/__pycache__/**"
+   ```
+
+### Missing Baseline Seal
+
+```bash
+# Create initial seal
+stella facet seal --image myapp:v1.0.0 --tenant production
+
+# Or skip quota check for first build
+stella scan --image myapp:v1.0.0 --skip-facet-quota
+```
+
+### VEX Draft Not Generated
+
+1. Verify action is `auto-vex` not `warn`:
+   ```yaml
+   facets:
+     binaries:
+       action: auto-vex  # Not 'warn'
+   ```
+
+2. Check VEX emitter is enabled:
+   ```bash
+   stella config get excititor.vex.facetDriftEnabled
+   ```
+
+---
+
+## Best Practices
+
+1. **Start with `moderate` profile** in staging, tune based on observations
+2. **Use `strict` for production** with explicit allowlists
+3. **Review auto-VEX drafts daily** to prevent backlog
+4. **Seal after each release** to establish new baseline
+5. **Monitor quota metrics** to detect configuration drift

+
+## 1. Chain Verification Failure
+
+### Symptoms
+- Alert: `HlcChainVerificationFailure`
+- Metric: `scheduler_chain_verification_failures_total` increasing
+- Log: `Chain verification failed: expected {expected}, got {actual}`
+
+### Severity
+**Critical** - Indicates potential data tampering or corruption.
+
+### Investigation Steps
+
+1. **Identify the affected chain segment**:
+   ```sql
+   SELECT 
+       job_id, 
+       t_hlc, 
+       encode(prev_link, 'hex') as prev_link,
+       encode(link, 'hex') as link,
+       created_at
+   FROM scheduler.scheduler_log
+   WHERE tenant_id = '<tenant_id>'
+   ORDER BY t_hlc DESC
+   LIMIT 100;
+   ```
+
+2. **Find the break point**:
+   ```sql
+   WITH chain AS (
+       SELECT 
+           job_id,
+           t_hlc,
+           prev_link,
+           link,
+           LAG(link) OVER (ORDER BY t_hlc) as expected_prev
+       FROM scheduler.scheduler_log
+       WHERE tenant_id = '<tenant_id>'
+   )
+   SELECT * FROM chain
+   WHERE prev_link IS DISTINCT FROM expected_prev
+   ORDER BY t_hlc;
+   ```
+
+3. **Check for unauthorized modifications**:
+   - Review database audit logs
+   - Check for direct SQL updates bypassing the application
+
+4. **Verify chain head consistency**:
+   ```sql
+   SELECT * FROM scheduler.chain_heads
+   WHERE tenant_id = '<tenant_id>';
+   ```
+
+### Resolution
+
+**If corruption is isolated**:
+1. Mark affected jobs for re-processing
+2. Rebuild chain from the last valid point
+3. Update chain head
+
+**If tampering is suspected**:
+1. Escalate to Security team immediately
+2. Preserve all logs and database state
+3. Initiate incident response procedure
+
+---
+
+## 2. Clock Skew Issues
+
+### Symptoms
+- Alert: `HlcClockSkewExceedsTolerance`
+- Metric: `hlc_clock_skew_rejections_total` increasing
+- Log: `Clock skew exceeds tolerance: {skew}ms > {tolerance}ms`
+
+### Severity
+**Critical** - Can cause job ordering inconsistencies.
+
+### Investigation Steps
+
+1. **Check NTP synchronization**:
+   ```bash
+   # On affected node
+   timedatectl status
+   ntpq -p
+   chronyc tracking  # if using chrony
+   ```
+
+2. **Verify time sources**:
+   ```bash
+   ntpq -pn
+   ```
+
+3. **Check for leap second issues**:
+   ```bash
+   dmesg | grep -i leap
+   ```
+
+4. **Compare with other nodes**:
+   ```bash
+   for node in node-1 node-2 node-3; do
+     echo "$node: $(ssh $node date +%s.%N)"
+   done
+   ```
+
+### Resolution
+
+1. **Restart NTP client**:
+   ```bash
+   sudo systemctl restart chronyd  # or ntpd
+   ```
+
+2. **Force time sync**:
+   ```bash
+   sudo chronyc makestep
+   ```
+
+3. **Temporarily increase tolerance** (emergency only):
+   ```yaml
+   Scheduler:
+     Queue:
+       Hlc:
+         MaxClockSkewMs: 60000  # Increase from default 5000
+   ```
+
+4. **Restart affected service** to reset HLC state.
+
+---
+
+## 3. Time Offset Drift
+
+### Symptoms
+- Alert: `HlcPhysicalTimeOffset`
+- Metric: `hlc_physical_time_offset_seconds` > 0.5
+
+### Severity
+**Warning** - May cause timestamp anomalies in diagnostics.
+
+### Investigation Steps
+
+1. **Check current offset**:
+   ```promql
+   hlc_physical_time_offset_seconds{node_id="<node>"}
+   ```
+
+2. **Review HLC state**:
+   ```bash
+   curl -s http://localhost:5000/health/hlc | jq
+   ```
+
+3. **Check for high logical counter**:
+   If logical counter is very high, it indicates frequent same-millisecond events.
+
+### Resolution
+
+Usually self-correcting as wall clock advances. If persistent:
+1. Review job submission rate
+2. Consider horizontal scaling to distribute load
+
+---
+
+## 4. Merge Conflicts
+
+### Symptoms
+- Alert: `HlcMergeConflictRateHigh`
+- Metric: `airgap_merge_conflicts_total` increasing
+- Log: `Merge conflict: job {jobId} has conflicting payloads`
+
+### Severity
+**Warning** - May indicate duplicate job submissions or clock issues on offline nodes.
+
+### Investigation Steps
+
+1. **Identify conflict types**:
+   ```promql
+   sum by (conflict_type) (airgap_merge_conflicts_total)
+   ```
+
+2. **Review merge logs**:
+   ```bash
+   grep "merge conflict" /var/log/stellaops/scheduler.log | tail -100
+   ```
+
+3. **Check offline node clocks**:
+   - Were offline nodes synchronized before disconnection?
+   - How long were nodes offline?
+
+### Resolution
+
+1. **For duplicate jobs**: Use idempotency keys to prevent duplicates
+2. **For payload conflicts**: Review job submission logic
+3. **For ordering conflicts**: Verify NTP on all nodes before disconnection
+
+---
+
+## 5. Slow Air-Gap Sync
+
+### Symptoms
+- Alert: `HlcSyncDurationHigh`
+- Metric: `airgap_sync_duration_seconds` p95 > 30s
+
+### Severity
+**Warning** - Delays job processing.
+
+### Investigation Steps
+
+1. **Check bundle sizes**:
+   ```promql
+   histogram_quantile(0.95, airgap_bundle_size_bytes_bucket)
+   ```
+
+2. **Check database performance**:
+   ```sql
+   SELECT * FROM pg_stat_activity
+   WHERE state = 'active' AND query LIKE '%scheduler_log%';
+   ```
+
+3. **Review index usage**:
+   ```sql
+   EXPLAIN ANALYZE
+   SELECT * FROM scheduler.scheduler_log
+   WHERE tenant_id = '<tenant>'
+   ORDER BY t_hlc
+   LIMIT 1000;
+   ```
+
+### Resolution
+
+1. **Chunk large bundles**: Split bundles > 10K entries
+2. **Optimize database**: Ensure indexes are used
+3. **Increase resources**: Scale up database if needed
+
+---
+
+## 6. No Enqueues
+
+### Symptoms
+- Alert: `HlcEnqueueRateZero`
+- No jobs appearing in HLC queue
+
+### Severity
+**Info** - May be expected or indicate misconfiguration.
+
+### Investigation Steps
+
+1. **Check if HLC ordering is enabled**:
+   ```bash
+   curl -s http://localhost:5000/config | jq '.scheduler.queue.hlc'
+   ```
+
+2. **Verify service is receiving jobs**:
+   ```promql
+   rate(scheduler_jobs_received_total[5m])
+   ```
+
+3. **Check for errors**:
+   ```bash
+   grep -i "hlc\|enqueue" /var/log/stellaops/scheduler.log | grep -i error
+   ```
+
+### Resolution
+
+1. If HLC should be enabled:
+   ```yaml
+   Scheduler:
+     Queue:
+       Hlc:
+         EnableHlcOrdering: true
+   ```
+
+2. If dual-write mode is needed:
+   ```yaml
+   Scheduler:
+     Queue:
+       Hlc:
+         DualWriteMode: true
+   ```
+
+---
+
+## 7. Batch Snapshot Failures
+
+### Symptoms
+- Alert: `HlcBatchSnapshotFailures`
+- Missing DSSE-signed batch proofs
+
+### Severity
+**Warning** - Audit proofs may be incomplete.
+
+### Investigation Steps
+
+1. **Check signing key**:
+   ```bash
+   stella signer status
+   ```
+
+2. **Verify DSSE configuration**:
+   ```bash
+   curl -s http://localhost:5000/config | jq '.scheduler.queue.hlc.batchSigning'
+   ```
+
+3. **Check database connectivity**:
+   ```sql
+   SELECT 1;  -- Simple connectivity test
+   ```
+
+### Resolution
+
+1. **Refresh signing credentials**
+2. **Check certificate expiry**
+3. **Verify database permissions for batch_snapshots table**
+
+---
+
+## 8. Duplicate Node ID
+
+### Symptoms
+- Alert: `HlcDuplicateNodeId`
+- Multiple instances with same node_id
+
+### Severity
+**Critical** - Will cause chain corruption.
+
+### Investigation Steps
+
+1. **Identify affected instances**:
+   ```promql
+   group by (node_id, instance) (hlc_ticks_total)
+   ```
+
+2. **Check node ID configuration**:
+   ```bash
+   # On each instance
+   grep -r "NodeId" /etc/stellaops/
+   ```
+
+### Resolution
+
+**Immediate action required**:
+1. Stop one of the duplicate instances
+2. Reconfigure with unique node ID
+3. Restart and verify
+4. Check chain integrity for affected time period
+

 ## Simulation guidance
-- Default simulator: `ops/crypto/sim-crypto-service` + provider `sim.crypto.remote` (see `docs/security/crypto-simulation-services.md`).
-- Use the simulator to close sprints until certified evidence is available; keep "non-certified" labels in RootPack manifests.
-- Quick simulation steps:
-  1) `docker build -t sim-crypto -f ops/crypto/sim-crypto-service/Dockerfile ops/crypto/sim-crypto-service`
-  2) `docker run --rm -p 8080:8080 sim-crypto`
-  3) Set `STELLAOPS_CRYPTO_ENABLE_SIM=1` and `STELLAOPS_CRYPTO_SIM_URL=http://localhost:8080`
-  4) Keep `sim.crypto.remote` first in `PreferredProviders` for the target profile.
-  5) Optional smoke harness (no VSTest): `dotnet run --project ops/crypto/sim-crypto-smoke/SimCryptoSmoke.csproj -c Release` with `SIM_PROFILE=ru-free|ru-paid|sm|eidas|fips|kcmvp|pq` and optional `SIM_MESSAGE`/`SIM_ALGORITHMS`.
+
+Use simulation paths when licensed hardware or certified modules are unavailable. They keep the registry/profile contracts stable while waiting for customer licenses (CryptoPro), QSCD devices (eIDAS), KCMVP modules, or SM PKCS#11 tokens.
+
+### Unified simulator (sim-crypto-service)
+
+- **Location:** `ops/crypto/sim-crypto-service/`
+- **Provider ID:** `sim.crypto.remote`
+- **Algorithms covered:**
+  - GOST: `GOST12-256`, `GOST12-512`, `ru.magma.sim`, `ru.kuznyechik.sim` (deterministic HMAC-SHA256)

+- The `SimRemoteProviderOptions.Algorithms` default list includes the IDs above; extend if you add new aliases.
+
+### Quick simulation steps
+
+1. Build and run:
+   ```bash
+   docker build -t sim-crypto -f ops/crypto/sim-crypto-service/Dockerfile ops/crypto/sim-crypto-service
+   docker run --rm -p 8080:8080 sim-crypto
+   ```
+
+2. Configure environment:
+   - Set `STELLAOPS_CRYPTO_ENABLE_SIM=1` to append `sim.crypto.remote` to registry ordering.
+   - Point the client: `STELLAOPS_CRYPTO_SIM_URL=http://localhost:8080` or bind `StellaOps:Crypto:Sim:BaseAddress`.
+   - Keep `sim.crypto.remote` first in `PreferredProviders` for the target profile.
+
+3. Quick check (curl):
+   ```bash
+   curl -s -X POST http://localhost:8080/sign -d '{"message":"stellaops-sim-check","algorithm":"SM2"}'
+   ```
+
+4. Smoke harnesses (no VSTest):
+   - **PowerShell:** `ops/crypto/run-sim-smoke.ps1` (args: `-BaseUrl http://localhost:5000 -SimProfile sm|ru-free|ru-paid|eidas|fips|kcmvp|pq`)
+   - **Headless:** `dotnet run --project ops/crypto/sim-crypto-smoke/SimCryptoSmoke.csproj -c Release` with `SIM_PROFILE=ru-free|ru-paid|sm|eidas|fips|kcmvp|pq` and optional `SIM_MESSAGE`/`SIM_ALGORITHMS=SM2,pq.sim,ES256`.
+
+Use the simulator to close sprints until certified evidence is available; keep "non-certified" labels in RootPack manifests.
 
 ## Evidence expectations
 - JWKS export from Authority/Signer for the active profile.

-## Regional notes
-- **RU (GOST)**: OSS remote signer available at `docs/security/openssl-gost-remote.md`. Licensed CryptoPro path is Linux-only via `ops/cryptopro/linux-csp-service` (customer debs, `CRYPTOPRO_ACCEPT_EULA=1`); use the simulator above when licensing is unavailable.
-- **CN (SM)**: Hardware/PKCS#11 bring-up in `docs/security/sm-hardware-simulation.md`. Legacy SM-only simulator is retired; use `sim-crypto-service` for SM2 tests.
-- **FIPS / eIDAS / KCMVP**: Hardware/QSCD runbook in `docs/security/fips-eidas-kcmvp-validation.md`. Until certified modules arrive, rely on the simulator above and keep profiles labeled “non-certified.”
-- **PQ**: Built-in `pq.soft` remains the baseline; the simulator is available for integration tests that expect a remote signer.

 # Scopes and Roles
 
+> **Canonical Reference:** For the complete, authoritative list of 90+ scopes with role bundles and configuration examples, see [authority-scopes.md](./authority-scopes.md).
+
 This document defines the **scope taxonomy** and how scopes map to roles across StellaOps. It is intentionally cross-cutting and does not attempt to list every module-specific scope; module dossiers and gateway contracts are the source of truth for per-surface requirements.

+# EvidenceLocker Export Library Charter
+
+## Mission
+- Export deterministic evidence bundles for offline verification.
+
+## Responsibilities
+- Implement tar.gz export, manifest/metadata serialization, and checksum generation.
+- Enforce deterministic ordering, timestamps, permissions, and offline-friendly outputs.
+- Keep export behavior aligned with docs/modules/evidence-locker/export-format.md.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/evidence-locker/architecture.md
+- docs/modules/evidence-locker/export-format.md
+
+## Working Agreement
+- Use TimeProvider and injected ID generators for timestamps and identifiers.
+- Validate file paths to prevent traversal in tar entries and output paths.
+- Keep outputs deterministic (ordering, metadata, invariant formatting).
+- Propagate CancellationToken for async operations.
+
+## Testing Strategy
+- Unit tests for checksum coverage, manifest ordering, and export determinism.
+- Tests for tar/gzip metadata (permissions, timestamps) and path validation.

+# ReachGraph Module Charter
+
+## Mission
+- Provide deterministic reachability graph storage and query services with replayable proofs.
+
+## Responsibilities
+- Maintain reachability graph schema, canonicalization, and digest computation.
+- Provide WebService endpoints for ingest, slice queries, and replay verification.
+- Preserve content-addressed storage and DSSE signing hooks.
+- Enforce offline-first operation and stable ordering.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/reach-graph/architecture.md
+- docs/contracts/richgraph-v1.md
+
+## Working Agreement
+- Deterministic outputs: stable ordering, RFC 8785 JSON canonicalization, fixed timestamps via TimeProvider.
+- Use DSSE helpers for signing and verification; do not reimplement PAE.
+- Use InvariantCulture for parsing or formatting that affects hashes.
+- Propagate CancellationToken through all async calls.
+- No external network calls beyond configured stores; remain air-gap friendly.
+
+## Testing Strategy
+- Unit tests for canonicalization, digests, and slice builders.
+- Integration tests for ingest, slice, and replay endpoints.
+- Determinism tests: same inputs yield identical digests and slices.

+# Scanner Gate Benchmarks Charter
+
+## Mission
+- Benchmark VEX gate policy evaluation performance deterministically.
+
+## Responsibilities
+- Provide reproducible BenchmarkDotNet runs for gate evaluation throughput.
+- Keep benchmark inputs deterministic and offline-friendly.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/scanner/architecture.md
+
+## Working Agreement
+- Use fixed seeds and stable inputs for deterministic benchmarks.
+- Avoid network dependencies and nondeterministic clocks.
+- Keep benchmark overhead minimal and isolated from core logic.
+
+## Testing Strategy
+- Benchmarks should be runnable in Release without external services.

+- Ensure report ID and card ordering assertions are deterministic.
+
+## Testing
+- Cover security/ABI/package/unknowns card generators and report filtering.

+# AGENTS - Scanner SchemaEvolution Tests
+
+## Roles
+- QA / test engineer: maintain schema evolution tests and deterministic fixtures.
+- Backend engineer: update scanner storage schema contracts and migration fixtures.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/scanner/architecture.md
+- src/Scanner/AGENTS.md
+- Current sprint file under docs/implplan/SPRINT_*.md
+
+## Working Directory & Boundaries
+- Primary scope: src/Scanner/__Tests/StellaOps.Scanner.SchemaEvolution.Tests
+- Allowed dependencies: src/Scanner/__Libraries/**, src/__Tests/__Libraries/StellaOps.Testing.SchemaEvolution, src/__Tests/__Libraries/StellaOps.Infrastructure.Postgres.Testing
+- Avoid cross-module edits unless explicitly noted in the sprint file.
+
+## Determinism and Safety
+- Use deterministic migration inputs and fixed timestamps where applicable.
+- Avoid environment-dependent settings in schema fixtures.
+
+## Testing
+- Exercise upgrade/downgrade paths and seed data compatibility across versions.
+- Verify schema compatibility with concrete migrations, not stubs.

+# SmRemote Service Charter
+
+## Mission
+- Provide a remote SM2 signing service that integrates with the cryptography plugin stack.
+
+## Responsibilities
+- Host the SM2 signing API with strict input validation and auth.
+- Bridge requests to the configured remote HSM or key service.
+- Ensure deterministic signing outputs and audit logging.
+- Maintain offline-safe operation when remote endpoints are allowed.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/cryptography/architecture.md
+
+## Working Agreement
+- Never log key material, raw digests, or secrets.
+- Use TimeProvider and IGuidGenerator for timestamps and request ids.
+- Use InvariantCulture for parsing and formatting.
+- Propagate CancellationToken to all IO calls.
+- Network access only to configured HSM endpoints; no ambient network calls.
+
+## Testing Strategy
+- Unit tests for request validation and error mapping.
+- Integration tests with mocked HSM endpoints and deterministic fixtures.
+- Security tests for auth, scope enforcement, and input bounds.

+# Timeline Module - AGENTS.md
+
+## Module Overview
+
+The Timeline module provides a unified event timeline service for querying, replaying, and exporting HLC-ordered events across all StellaOps services.
+
+## Roles Expected
+
+- **Backend Engineer**: Implement API endpoints, query services, and replay orchestration
+- **QA Engineer**: Create integration tests with Testcontainers PostgreSQL
+
+## Key Documentation
+
+Before working on this module, read:
+
+1. [CLAUDE.md](../../CLAUDE.md) - Code quality rules (especially 8.2 TimeProvider, 8.18 DateTimeOffset, 8.19 HLC)
+2. [docs/modules/eventing/event-envelope-schema.md](../../docs/modules/eventing/event-envelope-schema.md)
+3. [docs/modules/scheduler/hlc-ordering.md](../../docs/modules/scheduler/hlc-ordering.md)
+
+## Working Agreements
+
+### Directory Ownership
+
+- **WebService**: `src/Timeline/StellaOps.Timeline.WebService/`
+- **Core Library**: `src/Timeline/__Libraries/StellaOps.Timeline.Core/`
+- **Tests**: `src/Timeline/__Tests/`
+
+### Dependencies
+
+- Depends on: `StellaOps.Eventing`, `StellaOps.HybridLogicalClock`, `StellaOps.Replay.Core`
+- Consumed by: UI Console (Timeline view), CLI (replay commands)
+
+### API Conventions
+
+1. All endpoints under `/api/v1/timeline`
+2. HLC timestamps returned as sortable strings
+3. Pagination via `limit`, `offset`, and `nextCursor`
+4. Export produces NDJSON by default
+
+### Testing Requirements
+
+1. Unit tests with `[Trait("Category", "Unit")]`
+2. Integration tests with `[Trait("Category", "Integration")]`
+3. Use `FakeTimeProvider` for deterministic tests
+4. Use Testcontainers for PostgreSQL integration tests
+
+## Module-Specific Rules
+
+### HLC Ordering
+
+- All queries return events ordered by HLC timestamp (ascending)
+- Critical path analysis uses wall-clock duration but references HLC for linking
+- Replay must preserve HLC ordering
+
+### Export Format
+
+```ndjson
+{"event_id":"abc123","t_hlc":"1704585600000:0:node1","correlation_id":"scan-1","kind":"ENQUEUE",...}
+{"event_id":"def456","t_hlc":"1704585600001:0:node1","correlation_id":"scan-1","kind":"EXECUTE",...}
+```
+
+### Replay Contract
+
+- Replay is read-only (dry-run mode)
+- Verify mode compares replayed state to stored state
+- Replay operations are idempotent

+# Timeline WebService Module Charter
+
+## Mission
+- Provide timeline API endpoints and service orchestration.
+
+## Responsibilities
+- Implement HTTP endpoints and request validation.
+- Orchestrate persistence and timeline workflows.
+- Enforce deterministic ordering in responses.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/timeline-indexer/architecture.md
+- docs/modules/timeline-indexer/README.md
+
+## Working Agreement
+- Deterministic ordering and invariant formatting.
+- Use TimeProvider and IGuidGenerator where timestamps or IDs are created.
+- Propagate CancellationToken for async operations.
+
+## Testing Strategy
+- API tests for validation and error handling.
+- Determinism checks for response ordering.

+# Timeline Core Module Charter
+
+## Mission
+- Provide timeline core models and deterministic ordering logic.
+
+## Responsibilities
+- Define timeline domain models and validation rules.
+- Implement ordering and partitioning logic for timeline events.
+- Keep serialization deterministic and invariant.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/timeline-indexer/architecture.md
+- docs/modules/timeline-indexer/README.md
+
+## Working Agreement
+- Deterministic ordering and invariant formatting.
+- Use TimeProvider and IGuidGenerator where timestamps or IDs are created.
+- Propagate CancellationToken for async operations.
+
+## Testing Strategy
+- Unit tests for ordering, validation, and serialization.
+- Determinism tests for stable outputs.

+# Timeline Core Tests Charter
+
+## Mission
+- Verify timeline core query, replay, and export logic.
+
+## Responsibilities
+- Cover ordering, filtering, and pagination behavior.
+- Exercise replay and export determinism and cancellation.
+- Validate HLC range handling and edge cases.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/timeline-indexer/architecture.md
+- docs/modules/timeline-indexer/README.md
+
+## Working Agreement
+- Use fixed times and IDs in fixtures.
+- Avoid network dependencies in tests.
+
+## Testing Strategy
+- Unit tests for query, replay, and export logic.
+- Determinism tests for ordering and digests.

+# Timeline WebService Tests Charter
+
+## Mission
+- Verify timeline API endpoints, validation, and auth gating.
+
+## Responsibilities
+- Exercise request validation, paging, and response ordering.
+- Cover replay and export endpoints and status flows.
+- Validate authorization middleware behavior.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/timeline-indexer/architecture.md
+- docs/modules/timeline-indexer/README.md
+
+## Working Agreement
+- Use fixed times and IDs in fixtures.
+- Avoid network dependencies beyond the local test server.
+
+## Testing Strategy
+- Integration tests for endpoint behavior and auth.
+- Determinism checks for ordered responses.

+# AGENTS - Unknowns WebService
+
+## Roles
+- Backend engineer: .NET 10 Web API, DI wiring, and repository integration.
+- QA / test engineer: endpoint and authorization coverage, determinism checks.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/unknowns/architecture.md
+- src/Unknowns/AGENTS.md
+- Current sprint file under docs/implplan/SPRINT_*.md
+
+## Working Directory & Boundaries
+- Primary scope: src/Unknowns/StellaOps.Unknowns.WebService
+- Test scope: src/Unknowns/__Tests/StellaOps.Unknowns.WebService.Tests
+- Avoid cross-module edits unless explicitly allowed in the sprint file.
+
+## Determinism and Safety
+- Use TimeProvider/IGuidGenerator for time and IDs.
+- Validate inputs (tenant id, pagination bounds, confidence thresholds).
+- Require authorization and derive tenant identity from claims, not headers.
+
+## Testing
+- Cover list/query endpoints, pagination bounds, and tenant isolation.
+- Add health check tests for database connectivity and error handling.

+# VexLens Module Charter
+
+## Mission
+- Compute deterministic consensus over VEX statements and expose conflict-aware APIs.
+
+## Responsibilities
+- Implement consensus algorithm and conflict detection.
+- Persist consensus history and emit deterministic exports.
+- Expose APIs for consensus, conflicts, and trust weight updates.
+- Maintain offline bundle formats for Export Center.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/vex-lens/architecture.md
+- docs/modules/excititor/architecture.md
+
+## Working Agreement
+- Deterministic ordering: sort by timestamps, trust tier, and confidence.
+- Use TimeProvider and IGuidGenerator; UTC timestamps.
+- Use InvariantCulture for formatting.
+- Propagate CancellationToken in async flows.
+- Preserve provenance fields in outputs.
+
+## Testing Strategy
+- Unit tests for consensus join, conflicts, and precedence.
+- Integration tests for API endpoints and exports.
+- Determinism tests for repeatable consensus and bundle outputs.

+# VulnExplorer Module Charter
+
+## Mission
+- Provide deterministic, auditable triage workflows and APIs for vulnerability findings.
+
+## Responsibilities
+- Maintain ledger models and append-only history.
+- Expose APIs for findings, actions, and exports.
+- Enforce RBAC and ABAC scopes and Authority integration.
+- Produce offline bundles with signed manifests.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/vuln-explorer/architecture.md
+- docs/modules/findings-ledger/schema.md
+
+## Working Agreement
+- Append-only ledger updates; never mutate past entries.
+- Deterministic ordering for exports and manifests.
+- Use TimeProvider and IGuidGenerator; UTC timestamps.
+- Use InvariantCulture for parsing and formatting.
+- Propagate CancellationToken in async flows.
+
+## Testing Strategy
+- Unit tests for ledger projections and validation.
+- Integration tests for API endpoints and authorization.
+- Determinism tests for export bundles.

+# Eventing Library Charter
+
+## Mission
+- Provide event envelope models and deterministic serialization helpers.
+
+## Responsibilities
+- Define event envelope schemas and validation helpers.
+- Provide serialization/parsing utilities with invariant culture.
+- Maintain envelope versioning and compatibility rules.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/eventing/event-envelope-schema.md
+
+## Working Agreement
+- Deterministic ordering and invariant formatting.
+- Use TimeProvider and IGuidGenerator where timestamps or IDs are created.
+- Propagate CancellationToken for async operations.
+
+## Testing Strategy
+- Unit tests for envelope validation and serialization round-trips.
+- Determinism tests for stable ordering and hashes.

+# Eventing Tests Charter
+
+## Mission
+- Verify eventing envelope contracts and deterministic serialization.
+
+## Responsibilities
+- Cover schema validation, parsing, and round-trip serialization.
+- Exercise edge cases and determinism behavior.
+
+## Required Reading
+- docs/README.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/platform/architecture-overview.md
+- docs/modules/eventing/event-envelope-schema.md
+
+## Working Agreement
+- Use fixed times and IDs for deterministic tests.
+- Avoid network dependencies in tests.
+
+## Testing Strategy
+- Unit tests for schema and serialization.
+- Regression tests for envelope compatibility.
