# Sprint Series 20260105_002 - HLC: Audit-Safe Job Queue Ordering
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This sprint series implements the "Audit-safe job queue ordering" product advisory, adding Hybrid Logical Clock (HLC) based ordering with cryptographic sequence proofs to the StellaOps Scheduler. This closes the ~30% compliance gap identified in the advisory analysis.
|
||||
|
||||
## Problem Statement
|
||||
|
||||
Current StellaOps architecture relies on:
|
||||
- Wall-clock timestamps (`TimeProvider.GetUtcNow()`) for job ordering
|
||||
- Per-module sequence numbers (local ordering, not global)
|
||||
- Hash chains only in downstream ledgers (Findings, Orchestrator Audit)
|
||||
|
||||
This creates risks in:
|
||||
- **Distributed deployments** with clock skew between nodes
|
||||
- **Offline/air-gap scenarios** where jobs enqueued offline must merge deterministically
|
||||
- **Audit forensics** where "prove job A preceded job B" requires global ordering
|
||||
|
||||

|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| HLC over Lamport | Physical time component improves debuggability |
|
||||
| Separate `scheduler_log` table | Avoid breaking changes to existing `jobs` table |
|
||||
| Chain link at enqueue | Ensures ordering proof exists before execution |
|
||||
| Feature flags | Gradual rollout; easy rollback |
|
||||
| DSSE signing optional | Not all deployments need attestation |
|
||||
|
||||
## Risk Register
|
||||
|
||||
| Risk | Probability | Impact | Mitigation |
|
||||
|------|-------------|--------|------------|
|
||||
| Performance regression | Medium | Medium | Benchmarks; feature flag for rollback |
|
||||
| Clock skew exceeds tolerance | Low | High | NTP hardening; pre-sync validation |
|
||||
| Migration complexity | Medium | Medium | Dual-write mode; gradual rollout |
|
||||
| Chain corruption | Low | Critical | Verification alerts; immutable logs |
|
||||
|
||||
## Success Criteria
|
||||
|
||||
1. **Determinism:** Same inputs produce same HLC order across restarts/nodes
|
||||
2. **Chain Integrity:** 100% tampering detection in verification tests
|
||||
3. **Offline Merge:** Jobs from multiple offline nodes merge in correct HLC order
|
||||
4. **Performance:** HLC tick > 100K/sec; chain verification < 100ms/1K entries
|
||||
5. **Replay:** HLC-ordered replay produces identical results
|
||||
|
||||
## Rollout Plan
|
||||
|
||||
### Phase 1: Shadow Mode (Week 1)
|
||||
- Deploy with `EnableHlcOrdering = false`, `DualWriteMode = true`
|
||||
- HLC timestamps recorded but not used for ordering
|
||||
- Verify chain integrity on shadow writes
|
||||
|
||||
### Phase 2: Canary (Week 2)
|
||||
- Enable `EnableHlcOrdering = true` for 5% of tenants
|
||||
- Monitor metrics: latency, errors, chain verifications
|
||||
- Compare results between HLC and legacy ordering
|
||||
|
||||
### Phase 3: General Availability (Week 3)
|
||||
- Gradual rollout to all tenants
|
||||
- Disable `DualWriteMode` after 1 week of stable GA
|
||||
- Deprecate legacy ordering path
|
||||
|
||||
### Phase 4: Offline Features (Week 4+)
|
||||
- Enable air-gap bundle export/import with HLC
|
||||
- Test multi-node merge scenarios
|
||||
- Document operational procedures
|
||||
|
||||

## Phase 2: Unified Event Timeline (Extension)
|

|
||||
> **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
|
||||
|
||||

# Sprint 20260106_001_003_BINDEX - Symbol Table Diff
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Extend `PatchDiffEngine` with symbol table comparison capabilities to track exported/imported symbol changes, version maps, and GOT/PLT table modifications between binary versions.
|
||||
|
||||
- **Working directory:** `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Builders/`
|
||||
- **Evidence:** SymbolTableDiff model, analyzer, tests, integration with MaterialChange
|
||||
|
||||
## Problem Statement
|
||||
|
||||
The product advisory requires **per-layer diffs** including:
|
||||
> **Symbols:** exported symbols and version maps; highlight ABI-relevant changes.
|
||||
|
||||
Current state:
|
||||
- `PatchDiffEngine` compares **function bodies** (fingerprints, CFG, basic blocks)
|
||||
- `DeltaSignatureGenerator` creates CVE signatures at function level
|
||||
- No comparison of:
|
||||
- Exported symbol table (.dynsym, .symtab)
|
||||
- Imported symbols and version requirements (.gnu.version_r)
|
||||
- Symbol versioning maps (.gnu.version, .gnu.version_d)
|
||||
- GOT/PLT entries (dynamic linking)
|
||||
- Relocation entries
|
||||
|
||||
**Gap:** Symbol-level changes between binaries are not detected or reported.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Depends on:** StellaOps.BinaryIndex.Disassembly (for ELF/PE parsing)
|
||||
- **Blocks:** SPRINT_20260106_001_004_LB (orchestrator uses symbol diffs)
|
||||
- **Parallel safe:** Extends existing module; no conflicts
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- docs/modules/binary-index/architecture.md
|
||||
- src/BinaryIndex/AGENTS.md
|
||||
- Existing PatchDiffEngine at `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Builders/`

## Acceptance Criteria
|
||||
|
||||
1. **Completeness:** Extract exports, imports, versions, GOT/PLT from ELF and PE
|
||||
2. **Change Detection:** Identify added, removed, modified, renamed symbols
|
||||
3. **ABI Assessment:** Classify compatibility level with breaking change details
|
||||
4. **Rename Detection:** Match renames via fingerprint similarity (threshold 0.7)
|
||||
5. **MaterialChange Integration:** Symbol changes appear as `scope: symbol` in diffs
|
||||
6. **Test Coverage:** Unit tests for all extractors, golden fixtures for known binaries
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Content-addressed diff IDs | Enables caching and deduplication |
|
||||
| ABI compatibility scoring | Provides quick triage of binary changes |
|
||||
| Fingerprint-based rename detection | Handles version-to-version symbol renames |
|
||||
| Separate ELF/PE extractors | Different binary formats require different parsing |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Large symbol tables | Paginate results; index by name |
|
||||
| False rename detection | Confidence threshold; manual review for low confidence |
|
||||
| Stripped binaries | Graceful degradation; note limited analysis |
|
||||

# 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_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
|
||||
|
||||

# 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

||||

||||

### Integration Points
|
||||
|
||||
The Event SDK integrates with existing services via dependency injection:
|
||||
|
||||
| Service | Integration Point | Event Kinds |
|
||||
|---------|-------------------|-------------|
|
||||
| Scheduler | `ISchedulerService.EnqueueAsync` | ENQUEUE, DEQUEUE, EXECUTE, COMPLETE, FAIL |
|
||||
| AirGap | `IAirGapSyncService.ImportAsync` | IMPORT, EXPORT, MERGE, CONFLICT |
|
||||
| Attestor | `IAttestorService.SignAsync` | ATTEST, VERIFY |
|
||||
| Policy | `IPolicyEngine.EvaluateAsync` | EVALUATE, GATE_PASS, GATE_FAIL |
|
||||
| VexLens | `IVexConsensusService.ComputeAsync` | CONSENSUS, OVERRIDE |

## 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
|
||||
