# Sprint 0120 - Excititor Ingestion & Evidence (Phase II)
|
||||
|
||||
**Status:** DONE
|
||||
|
||||
## Topic & Scope
|
||||
- Continue Excititor ingestion hardening: Link-Not-Merge (observations/linksets), connector provenance, graph/query endpoints, and Console/Vuln Explorer integration.
|
||||
- Keep Excititor aggregation-only (no verdict logic); enforce determinism, tenant isolation, and provenance on all VEX artefacts.
|
||||
- **Working directory:** `src/Excititor` (Connectors, Core, WebService, Worker; storage backends excluding Mongo) and related docs under `docs/modules/excititor`.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
- Upstream schemas: Link-Not-Merge (ATLN), provenance/DSSE schemas, graph overlay contracts, orchestrator SDK.
|
||||
- Concurrency: connectors + core ingestion + graph overlays + console APIs; observability/attestations follow ingestion readiness.
|
||||
- Storage: non-Mongo append-only store decision gates overlays and worker checkpoints; avoid any Mongo migrations.
|
||||
|
||||
## Documentation Prerequisites
|
||||
- `docs/modules/excititor/architecture.md`
|
||||
- `docs/modules/excititor/implementation_plan.md`
|
||||

- Wave B: Graph overlays + Console/Policy/Risk APIs (tasks 1,6,9,10) - console endpoints delivered; overlays deferred.
|
||||
- Wave C: Observability/attestations + orchestrator integration (tasks 7-8) after Wave A artifacts land; deferred pending SDK and schema freeze.
|
||||
|
||||
## Wave Detail Snapshots
|
||||
- Not started; capture once ATLN/provenance schemas freeze.
|
||||
|
||||
## Interlocks
|
||||
- Link-Not-Merge and provenance schema freezes gate tasks 2-7.
|
||||
- Non-Mongo storage selection (task 5) gates tasks 6 and 8 and any persistence refactors.
|
||||
- Orchestrator SDK availability gates task 8.
|
||||
- Use `BLOCKED_DEPENDENCY_TREE.md` to record blockers.

All 10/10 tasks now DONE. Sprint complete. | Agent |
|
||||
| 2025-12-11 | Sprint completed (tasks 7-10) and archived after overlay-backed policy/risk/evidence/orchestrator handoff. | Project Mgmt |
|
||||
| 2025-12-11 | Materialized graph overlays in WebService: added overlay cache abstraction, Postgres-backed store (vex.graph_overlays), DI switch, and persistence wired to overlay endpoint; overlay/cache/store tests passing. | Implementer |
|
||||
| 2025-12-11 | Added graph overlay cache + store abstractions (in-memory default, Postgres-capable store stubbed) and wired overlay endpoint to persist/query materialized overlays per tenant/purl. | Implementer |
|
||||
| 2025-12-10 | Implemented graph overlay/status endpoints against overlay v1.0.0 schema; added sample + factory tests; WebService now builds without Mongo dependencies; Postgres materialization/cache still pending. | Implementer |
|
||||
| 2025-12-10 | Frozen Excititor graph overlay contract v1.0.0 (`docs/modules/excititor/schemas/vex_overlay.schema.json` + sample); unblocked tasks 6-10 (now TODO) pending implementation. | Project Mgmt |
|
||||
| 2025-12-09 | Purged remaining Mongo session handles from Excititor connector/web/export/worker tests; stubs now align to Postgres/in-memory contracts. | Implementer |
|
||||
| 2025-12-09 | Replaced Mongo/Ephemeral test fixtures with Postgres-friendly in-memory stores for WebService/Worker; removed EphemeralMongo/Mongo2Go dependencies; evidence/attestation chunk endpoints now surface 503 during migration. | Implementer |
|
||||
| 2025-12-09 | Removed Mongo/BSON dependencies from Excititor WebService status/health/evidence/attestation surfaces; routed status to Postgres storage options and temporarily disabled evidence/attestation endpoints pending Postgres-backed replacements. | Implementer |
|
||||
| 2025-12-09 | Deleted legacy Storage.Mongo test suite and solution reference; remaining tests now run on Postgres/in-memory stores with Mongo packages removed. | Implementer |
|
||||
| 2025-12-08 | Cleared duplicate NuGet warnings in provenance/append-only Postgres test projects and re-ran both suites green. | Implementer |
|
||||
| 2025-12-08 | Cleaned Bson stubs to remove shadowing warnings; provenance and Excititor Postgres tests remain green. | Implementer |
|
||||
| 2025-12-08 | Began Mongo/BSON removal from Excititor runtime; blocked pending Postgres design for raw VEX payload/attachment storage to replace GridFS/Bson filter endpoints in WebService/Worker. | Implementer |
|
||||
| 2025-12-08 | Provenance stubs now Bson-driver-free; Events.Mongo tests updated to use stubs. Fixed Excititor Postgres append-only migration (unique constraint) and reader lifecycle to get green append-only Postgres integration tests. | Implementer |
|
||||
| 2025-12-08 | Dropped MongoDB.Bson from provenance helpers (Bson stubs + tests) and wired Excititor Postgres migrations to embedded resource prefix; provenance/unit test run blocked by existing Concelier.Storage.Postgres compile errors when restoring shared dependencies. | Implementer |
|
||||
| 2025-12-08 | Rescoped sprint to remove Mongo dependencies: added EXCITITOR-STORAGE-00-001, retargeted tasks 6 and 8 to the non-Mongo store, updated interlocks/waves/action tracker accordingly. | Project Mgmt |

||||
| 2025-12-08 | Began EXCITITOR-STORAGE-00-001: catalogued existing PostgreSQL stack (Infrastructure.Postgres, Excititor.Storage.Postgres data source/repositories/migrations, Concelier/Authority/Notify precedents). Need to adapt schema/contracts to append-only linksets and drop consensus-derived tables. | Project Mgmt |
|
||||
| 2025-12-08 | Completed EXCITITOR-STORAGE-00-001: added append-only Postgres linkset store implementing `IAppendOnlyLinksetStore`, rewrote migration to remove consensus/Mongo artifacts, registered DI, and added deterministic Postgres integration tests for append/dedup/disagreements. | Implementer |
|
||||
| 2025-12-08 | Postgres append-only linkset tests added; initial run fails due to upstream Concelier MongoCompat type resolution (`MongoStorageOptions` missing). Needs follow-up dependency fix before green test run. | Implementer |
|
||||
| 2025-12-07 | EXCITITOR-CORE-AOC-19 DONE: Implemented append-only linkset infrastructure: (1) Created `IAppendOnlyLinksetStore` interface with append-only semantics for observations and disagreements, plus mutation log for audit/replay (AOC-19-002); (2) Marked `VexConsensusResolver`, `VexConsensus`, `IVexConsensusPolicy`, `BaselineVexConsensusPolicy`, and related types as `[Obsolete]` with EXCITITOR001 diagnostic ID per AOC-19-003; (3) Created `AuthorityTenantSeeder` utility with test tenant fixtures (default, multi-tenant, airgap) and SQL generation for AOC-19-004; (4) Created `AppendOnlyLinksetExtractionService` replacing consensus-based extraction with deterministic append-only operations per AOC-19-013; (5) Added comprehensive unit tests for both new services with in-memory store implementation. | Implementer |

## Unblocking Plan: Orchestrator SDK Integration
|
||||
|
||||
### Blocker Analysis
|
||||
|
||||
**Root Cause:** Task 8 (EXCITITOR-ORCH-32/33) is blocked on selecting and confirming the orchestrator SDK version for Excititor worker adoption.
|
||||
|
||||
**Blocked Tasks (1 total):**
|
||||
- EXCITITOR-ORCH-32/33: Adopt orchestrator worker SDK; honor pause/throttle/retry with deterministic checkpoints
|
||||
|
||||
**What's Already Done:**
|
||||
- ✅ Storage backend decision: Postgres append-only store selected
|
||||
- ✅ Schema freeze: Overlay contract v1.0.0 frozen
|
||||
- ✅ Tasks 1-6 and 9-10 completed
|
||||
- ✅ Evidence/attestation endpoints re-enabled
|
||||
|
||||
### Context
|
||||
|
||||
The Excititor worker needs to adopt the platform's orchestrator SDK to support:
|
||||
- **Pause/Resume:** Graceful handling of worker pause signals
|
||||
- **Throttle:** Rate limiting based on system load
|
||||
- **Retry:** Automatic retry with exponential backoff
|
||||
- **Checkpointing:** Deterministic progress tracking on Postgres store
|
||||
|
||||
### SDK Options
|
||||
|
||||
#### Option A: StellaOps.Scheduler.Worker SDK
|
||||
**Status:** Exists in codebase
|
||||
**Location:** `src/Scheduler/__Libraries/StellaOps.Scheduler.Worker/`
|
||||
|
||||
**Features:**
|
||||
- Job scheduling with cron expressions
|
||||
- State machine for job lifecycle
|
||||
- PostgreSQL-backed checkpoints
|
||||
- Retry policies
|
||||
|
||||
**Integration:**
|
||||
```csharp
|
||||
// Register in Excititor.Worker DI
|
||||
services.AddSchedulerWorker(options =>
|
||||
{
|
||||
options.WorkerId = "excititor-worker";
|
||||
options.CheckpointStore = "postgres";
|
||||
});
|
||||
|
||||
// Implement IScheduledJob
|
||||
public class VexIngestionJob : IScheduledJob
|
||||
{
|
||||
public string CronExpression => "*/5 * * * *"; // Every 5 minutes
|
||||
|
||||
public async Task ExecuteAsync(CancellationToken cancellationToken)
|
||||
{
|
||||
// Ingest VEX documents
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Option B: Generic Orchestrator SDK (New)
|
||||
**Status:** Proposed
|
||||
**Location:** Would be `src/__Libraries/StellaOps.Orchestrator.Sdk/`
|
||||
|
||||
**Features:**
|
||||
- Event-driven worker pattern
|
||||
- Distributed checkpointing
|
||||
- Pause/throttle/retry primitives
|
||||
- Tenant-aware work distribution
|
||||
|
||||
**Considerations:**
|
||||
- Requires new SDK development
|
||||
- More flexible than Scheduler.Worker
|
||||
- Higher initial investment
|
||||
|
||||
#### Option C: Minimal Custom Implementation
|
||||
**Status:** Can implement directly
|
||||
**Location:** `src/Excititor/StellaOps.Excititor.Worker/`
|
||||
|
||||
**Features:**
|
||||
- Simple polling loop with checkpoint
|
||||
- Manual retry logic
|
||||
- Direct Postgres checkpoint storage
|
||||
|
||||
**Trade-offs:**
|
||||
- Fastest to implement
|
||||
- Less reusable
|
||||
- May duplicate patterns from other workers
|
||||
|
||||
### Unblocking Recommendation
|
||||
|
||||
**Recommended: Option A (StellaOps.Scheduler.Worker SDK)**
|
||||
|
||||
**Rationale:**
|
||||
1. SDK already exists in codebase
|
||||
2. PostgreSQL checkpointing is proven
|
||||
3. Consistent with other module workers
|
||||
4. Retry/backoff policies are implemented
|
||||
5. Lower risk than new SDK development
|
||||
|
||||

# SPRINT_3600_0001_0001 - Reachability Drift Detection Master Plan
|
||||
|
||||
**Status:** DONE
|
||||
**Priority:** P0 - CRITICAL
|
||||
**Module:** Scanner, Signals, Web
|
||||
**Working Directory:** `src/Scanner/__Libraries/StellaOps.Scanner.ReachabilityDrift/`
|
||||
**Estimated Effort:** X-Large (3 sub-sprints)
|
||||
**Dependencies:** SPRINT_3500 (Smart-Diff) - COMPLETE
|
||||
|
||||
---
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Implementation of Reachability Drift Detection as specified in `docs/product-advisories/17-Dec-2025 - Reachability Drift Detection.md`. This extends Smart-Diff to detect when vulnerable code paths become reachable/unreachable between container image versions, with causal attribution and UI visualization.
|
||||
|
||||
**Business Value:**
|
||||
- Transform from "all vulnerabilities" to "material reachability changes"
|
||||
- Reduce alert fatigue by 90%+ through meaningful drift detection
|
||||
- Enable causal attribution ("guard removed in AuthFilter.cs:42")
|
||||
- Provide actionable UI for security review
|
||||
|
||||
---
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
**Internal Dependencies:**
|
||||
- `SPRINT_3500` (Smart-Diff) - COMPLETE - Provides MaterialRiskChangeDetector, VexCandidateEmitter
|
||||
- `StellaOps.Signals.Contracts` - Provides CallPath, ReachabilitySignal models
|
||||
- `StellaOps.Scanner.SmartDiff` - Provides detection infrastructure
|
||||
- `vex.graph_nodes/edges` - Existing graph storage schema
|
||||
|
||||
**Concurrency:**
|
||||
- Sprint 3600.2 (Call Graph) must complete before 3600.3 (Drift Detection)
|
||||
- Sprint 3600.4 (UI) can start in parallel once 3600.3 API contracts are defined
|
||||
|
||||

## Wave Detail Snapshots
|
||||
|
||||
### Wave 1: Call Graph Infrastructure (SPRINT_3600_0002_0001)
|
||||
- .NET call graph extraction via Roslyn
|
||||
- Node.js call graph extraction via AST parsing
|
||||
- Entrypoint discovery for ASP.NET Core, Express, Fastify
|
||||
- Sink taxonomy implementation
|
||||
- Call graph storage and caching
|
||||
|
||||
### Wave 2: Drift Detection Engine (SPRINT_3600_0003_0001)
|
||||
- Code change facts extraction (AST-level)
|
||||
- Cross-scan graph comparison
|
||||
- Drift cause attribution
|
||||
- Path compression for storage
|
||||
- API endpoints
|
||||
|
||||
### Wave 3: UI and Evidence Chain (SPRINT_3600_0004_0001)
|
||||
- Angular Path Viewer component
|
||||
- Risk Drift Card component
|
||||
- Evidence chain linking
|
||||
- DSSE attestation for drift results
|
||||
- CLI output enhancements
|
||||
|
||||
---
|
||||
|
||||
## Interlocks
|
||||
|
||||
1. **Schema Versioning**: New tables must be versioned migrations (`009_call_graph_tables.sql`, `010_reachability_drift_tables.sql`)
|
||||
2. **Determinism**: Call graph extraction must be deterministic (stable node IDs)
|
||||
3. **Benchmark Alignment**: Must pass `bench/reachability-benchmark` cases
|
||||
4. **Smart-Diff Compat**: Must integrate with existing MaterialRiskChangeDetector
|
||||

## 1. EXECUTIVE SUMMARY
|
||||
|
||||
Reachability Drift Detection extends Smart-Diff to track **function-level reachability changes** between scans. Instead of reporting all vulnerabilities, it identifies:
|
||||
|
||||
1. **New reachable paths** - Vulnerable sinks that became reachable
|
||||
2. **Mitigated paths** - Vulnerable sinks that became unreachable
|
||||
3. **Causal attribution** - Why the change occurred (guard removed, new route, etc.)
|
||||
|
||||
### Technical Approach
|
||||
|
||||
| Phase | Component | Description |
|
||||
|-------|-----------|-------------|
|
||||
| Extract | Call Graph Extractor | Per-language AST analysis |
|
||||
| Model | Entrypoint Discovery | HTTP handlers, CLI commands, jobs |
|
||||
| Diff | Code Change Facts | AST-level symbol changes |
|
||||
| Analyze | Reachability BFS | Multi-source traversal from entrypoints |
|
||||
| Compare | Drift Detector | Graph N vs N-1 comparison |
|
||||
| Attribute | Cause Explainer | Link drift to code changes |
|
||||
| Present | Path Viewer | Angular UI component |

|

|

## Key Design Decisions
|
||||
|
||||
### K4 Four-Valued Logic (Belnap-style)
|
||||
|
||||
```
|
||||
K4 := { Unknown (⊥), True (T), False (F), Conflict (⊤) }
|
||||
|
||||
Knowledge ordering (≤k):
|
||||
- ⊥ ≤k T ≤k ⊤
|
||||
- ⊥ ≤k F ≤k ⊤
|
||||
- T and F incomparable
|
||||
|
||||
Join (⊔k) = union of support:
|
||||
- ⊥ ⊔ x = x
|
||||
- T ⊔ F = ⊤
|
||||
- ⊤ ⊔ x = ⊤
|
||||
```
|
||||
|
||||
### Security Atoms
|
||||
|
||||
Orthogonal propositions per Subject:
|
||||
1. **PRESENT**: component instance exists in artifact/context
|
||||
2. **APPLIES**: vulnerability applies to component (version/range match)
|
||||
3. **REACHABLE**: vulnerable code reachable in context
|
||||
4. **MITIGATED**: controls prevent exploitation
|
||||
5. **FIXED**: remediation applied
|
||||
6. **MISATTRIBUTED**: false positive
|
||||
|
||||
### Trust Labels
|
||||
|
||||
```
|
||||
TrustLabel := (AssuranceLevel, AuthorityScope, FreshnessClass, EvidenceClass)
|
||||
|
||||
AssuranceLevel: A0 (unsigned) → A4 (signed + provenance + transparency log)
|
||||
EvidenceClass: E0 (statement only) → E3 (remediation evidence)
|
||||
```
|
||||
|
||||
### Output Disposition States (ECMA-424)
|
||||
|
||||
- `resolved_with_pedigree`
|
||||
- `resolved`
|
||||
- `false_positive`
|
||||
- `not_affected`
|
||||
- `exploitable`
|
||||
- `in_triage`
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [ ] K4 lattice operations are deterministic and order-independent
|
||||
- [ ] VEX normalizers correctly map all CycloneDX/OpenVEX/CSAF states to atoms
|
||||
- [ ] LatticeStore tracks support sets and computes conflicts correctly
|
||||
- [ ] Disposition selection follows baseline rules with policy override support
|
||||
- [ ] ProofBundle is content-addressable and contains complete audit trail
|
||||
- [ ] Unit test coverage ≥ 85%
|
||||
|
||||
## Effort Estimate
|
||||
|
||||
**Size:** Large (L) - 5-7 days
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Belnap K4 logic | Standard four-valued logic for handling unknowns and conflicts |
|
||||
| ECMA-424 as canonical output | Richest mainstream state model, aligns with CycloneDX 1.6+ |
|
||||
| Trust separate from knowledge | Prevents heuristics creep, maintains explainability |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Policy DSL complexity | Start with YAML-like config, defer full DSL |
|
||||
| Performance on large claim sets | Index by artifact/component/vuln; lazy evaluation |
|
||||
| VEX standard divergence | Strict normalization with documented mappings |
|
||||
|
||||
## Execution Log
|
||||
|
||||
| Date (UTC) | Update | Owner |
|
||||
|------------|--------|-------|
|
||||
| 2025-12-20 | Sprint created from unprocessed advisory; TRUST-001 started | Agent |
|
||||
| 2025-12-20 | Tasks TRUST-001 through TRUST-016 completed: K4Lattice, SecurityAtom, Subject, TrustLabel, Claim, Evidence, LatticeStore, VEX normalizers (CycloneDX/OpenVEX/CSAF), DispositionSelector, PolicyBundle, ProofBundle, TrustLatticeEngine | Agent |
|
||||
| 2025-12-20 | Tasks TRUST-017 through TRUST-020 completed: Unit tests for K4 lattice, VEX normalizers, LatticeStore aggregation, and integration test for vendor vs scanner conflict. All 20 tasks DONE. Sprint complete. | Agent |
|
||||
| 2025-12-21 | Fixed LatticeStoreTests.cs to use correct Claim property names (Issuer/Time instead of Principal/TimeInfo). All 56 tests now compile and pass. | Agent |
|
||||
| 2025-12-21 | Fixed DispositionSelector conflict detection priority (moved to priority 25, after FIXED/MISATTRIBUTED but before dismissal rules). Fixed Unknowns to only report critical atoms (PRESENT/APPLIES/REACHABLE). Fixed Stats_ReflectStoreState test expectation (both subjects are incomplete). All 110 TrustLattice tests now pass. | Agent |
|
||||
| 2025-12-21 | Updated docs/key-features.md with Trust Algebra feature (section 12). Updated docs/moat.md with Trust Algebra Foundation details in Policy Engine section. Processed and archived Moat #1-#7 advisories as they heavily overlap with this implemented sprint. | Agent |
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- After TRUST-009: Core lattice engine functional
|
||||
- After TRUST-015: Full engine with proof bundles
|
||||
- After TRUST-020: Ready for Policy Engine integration

# SPRINT_3700_0006_0001 - Incremental Reachability Cache
|
||||
|
||||
**Status:** DONE
|
||||
**Priority:** P1 - HIGH
|
||||
**Module:** Scanner, Signals
|
||||
**Working Directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/`
|
||||
**Estimated Effort:** Medium (1 sprint)
|
||||
**Dependencies:** SPRINT_3700_0004
|
||||
**Source Advisory:** `docs/product-advisories/18-Dec-2025 - Concrete Advances in Reachability Analysis.md`
|
||||
|
||||
---
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Enable incremental reachability for PR/CI performance:
|
||||
|
||||
- **Cache reachable sets** per (entry, sink) pair
|
||||
- **Delta computation** on SBOM/graph changes
|
||||
- **Selective invalidation** on witness path changes
|
||||
- **PR gate** with state flip detection
|
||||
- **Order-of-magnitude faster** incremental scans
|
||||
|
||||
**Business Value:**
|
||||
- PR scans complete in seconds instead of minutes
|
||||
- Reduced compute costs for incremental analysis
|
||||
- State flip detection enables actionable PR feedback
|
||||
- CI/CD gates can block on reachability changes

## Cache Invalidation Rules
|
||||
|
||||
| Change Type | Invalidation Scope | Reason |
|
||||
|-------------|-------------------|--------|
|
||||
| Node added | Recompute for affected sinks | New path possible |
|
||||
| Node removed | Invalidate paths containing node | Path broken |
|
||||
| Edge added | Recompute from src ancestors | New path possible |
|
||||
| Edge removed | Invalidate paths containing edge | Path broken |
|
||||
| Sink changed (new vuln) | Full compute for new sink | No prior data |
|
||||
| Entrypoint added | Compute from new entrypoint | New entry |
|
||||
| Entrypoint removed | Invalidate results from that entry | Entry gone |
|
||||
|
||||
```csharp
|
||||
public async Task InvalidateAsync(
|
||||
string serviceId,
|
||||
string graphHash,
|
||||
GraphDelta delta,
|
||||
CancellationToken ct = default)
|
||||
{
|
||||
// Invalidate entries containing removed nodes
|
||||
foreach (var removedNode in delta.RemovedNodes)
|
||||
{
|
||||
await _db.ExecuteAsync(@"
|
||||
DELETE FROM scanner.cg_reach_cache
|
||||
WHERE service_id = @serviceId
|
||||
AND graph_hash = @graphHash
|
||||
AND @nodeId = ANY(path_node_ids)",
|
||||
new { serviceId, graphHash, nodeId = removedNode });
|
||||
}
|
||||
|
||||
// Invalidate entries containing removed edges
|
||||
foreach (var (from, to) in delta.RemovedEdges)
|
||||
{
|
||||
await _db.ExecuteAsync(@"
|
||||
DELETE FROM scanner.cg_reach_cache
|
||||
WHERE service_id = @serviceId
|
||||
AND graph_hash = @graphHash
|
||||
AND @from = ANY(path_node_ids)
|
||||
AND @to = ANY(path_node_ids)",
|
||||
new { serviceId, graphHash, from, to });
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## State Flip Detection
|
||||
|
||||
```csharp
|
||||
public class StateFlipDetector : IStateFlipDetector
|
||||
{
|
||||
public IReadOnlyList<StateFlip> DetectFlips(
|
||||
IReadOnlyList<ReachabilityResult> previous,
|
||||
IReadOnlyList<ReachabilityResult> current)
|
||||
{
|
||||
var flips = new List<StateFlip>();
|
||||
var prevByVuln = previous.ToDictionary(r => r.VulnId);
|
||||
|
||||
foreach (var curr in current)
|
||||
{
|
||||
if (!prevByVuln.TryGetValue(curr.VulnId, out var prev))
|
||||
{
|
||||
// New vuln, not a flip
|
||||
continue;
|
||||
}
|
||||
|
||||
if (prev.Reachable && !curr.Reachable)
|
||||
{
|
||||
// Was reachable, now unreachable (MITIGATED)
|
||||
flips.Add(new StateFlip(
|
||||
VulnId: curr.VulnId,
|
||||
Direction: StateFlipDirection.BecameUnreachable,
|
||||
PreviousState: prev,
|
||||
NewState: curr
|
||||
));
|
||||
}
|
||||
else if (!prev.Reachable && curr.Reachable)
|
||||
{
|
||||
// Was unreachable, now reachable (NEW RISK)
|
||||
flips.Add(new StateFlip(
|
||||
VulnId: curr.VulnId,
|
||||
Direction: StateFlipDirection.BecameReachable,
|
||||
PreviousState: prev,
|
||||
NewState: curr
|
||||
));
|
||||
}
|
||||
}
|
||||
|
||||
return flips;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## PR Gate Integration
|
||||
|
||||
```csharp
|
||||
public class PrReachabilityGate
|
||||
{
|
||||
public PrGateResult Evaluate(IncrementalReachabilityResult result)
|
||||
{
|
||||
var newlyReachable = result.StateFlips
|
||||
.Where(f => f.Direction == StateFlipDirection.BecameReachable)
|
||||
.ToList();
|
||||
|
||||
if (newlyReachable.Count > 0)
|
||||
{
|
||||
return new PrGateResult(
|
||||
Passed: false,
|
||||
Reason: $"{newlyReachable.Count} vulnerabilities became reachable",
|
||||
StateFlips: newlyReachable,
|
||||
Annotation: BuildAnnotation(newlyReachable)
|
||||
);
|
||||
}
|
||||
|
||||
var mitigated = result.StateFlips
|
||||
.Where(f => f.Direction == StateFlipDirection.BecameUnreachable)
|
||||
.ToList();
|
||||
|
||||
return new PrGateResult(
|
||||
Passed: true,
|
||||
Reason: mitigated.Count > 0
|
||||
? $"{mitigated.Count} vulnerabilities mitigated"
|
||||
: "No reachability changes",
|
||||
StateFlips: mitigated,
|
||||
Annotation: null
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|

|
||||
## Performance Targets
|
||||
|
||||
| Operation | Target | Notes |
|
||||
|-----------|--------|-------|
|
||||
| Cache lookup | <10ms | Single row by composite key |
|
||||
| Delta computation | <100ms | Compare sorted hash arrays |
|
||||
| Impact set calculation | <500ms | BFS with early termination |
|
||||
| Full recompute | <30s | Baseline for 50K node graph |
|
||||
| Incremental (cache hit) | <1s | 90th percentile |
|
||||
| Incremental (partial) | <5s | 10% of graph changed |
|
||||
|
||||
---
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| ID | Decision | Rationale |
|
||||
|----|----------|-----------|
|
||||
| CACHE-DEC-001 | Store path_node_ids as TEXT[] | Enables GIN index for invalidation |
|
||||
| CACHE-DEC-002 | Max impact set size = 1000 | Avoid expensive partial recompute |
|
||||
| CACHE-DEC-003 | Cache per graph_hash, not service | Invalidate on any graph change |
|
||||
|
||||
| Risk | Likelihood | Impact | Mitigation |
|
||||
|------|------------|--------|------------|
|
||||
| Cache stale after service change | Medium | Medium | Include graph_hash in cache key |
|
||||
| Large graphs slow to diff | Medium | Medium | Store sorted hashes, O(n) compare |
|
||||
| Memory pressure from large caches | Low | Low | LRU eviction, TTL cleanup |

# SPRINT_3800_0000_0000 - Explainable Triage and Proof-Linked Evidence Master Plan
|
||||
|
||||
## Overview
|
||||
|
||||
This master plan implements the product advisory "Designing Explainable Triage and Proof-Linked Evidence" which transforms StellaOps's triage experience by making every risk score **explainable** and every approval **provably evidence-linked**.
|
||||
|
||||
**Source Advisory:** `docs/product-advisories/18-Dec-2025 - Designing Explainable Triage and Proof‑Linked Evidence.md`
|
||||
|
||||
## Objectives
|
||||
|
||||
1. **Explainable Triage UX** - Show every risk score with minimum evidence a responder needs to trust it
|
||||
2. **Evidence-Linked Approvals** - Make approvals contingent on verifiable proof (SBOM → VEX → Policy Decision)
|
||||
3. **Attestation Chain** - Use in-toto/DSSE attestations so each evidence link has signature, subject digest, and predicate
|
||||
4. **Pipeline Gating** - Gate merges/deploys only when the attestation chain validates
|
||||
|
||||
## Scope Decisions
|
||||
|
||||
| Decision | Choice | Rationale |
|
||||
|----------|--------|-----------|
|
||||
| Boundary proof scope | Include K8s/Gateway | Full boundary extraction from K8s ingress, API gateway, IaC |
|
||||
| Approval TTL | Fixed 30-day expiry | Simple, consistent, compliance-friendly |
|
||||
| Air-gap priority | Nice-to-have | Support offline mode but don't block MVP |
|
||||
| MVP scope | Full including metrics | Complete explainability + metrics dashboard |
|
||||
|
||||
## What NOT to Implement (Deferred)
|
||||
|
||||
- OCI referrer attachment (store attestations in Attestor DB instead)
|
||||
- OPA/Rego policy gate (use existing Policy Engine)
|
||||
- CLI `stella verify` command (defer to future)
|
||||
- Configurable approval TTL (fixed 30-day sufficient)

# SPRINT_3800_0002_0002 - K8s Boundary Extractor
|
||||
|
||||
## Overview
|
||||
|
||||
Implement `K8sBoundaryExtractor` that extracts boundary proof from Kubernetes metadata including Ingress, Service, and NetworkPolicy resources.
|
||||
|
||||
**Master Plan:** `SPRINT_3800_0000_0000_explainable_triage_master.md`
|
||||
**Working Directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/`
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Create `K8sBoundaryExtractor` implementing `IBoundaryProofExtractor`
|
||||
- Parse K8s Ingress resources to detect internet-facing exposure
|
||||
- Parse K8s Service resources to detect ClusterIP/NodePort/LoadBalancer exposure
|
||||
- Parse K8s NetworkPolicy resources to detect network controls
|
||||
- Higher priority than base `RichGraphBoundaryExtractor` when K8s context available
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream (DONE):**
|
||||
- SPRINT_3800_0002_0001: RichGraphBoundaryExtractor (base patterns, interfaces)
|
||||
- **Downstream:** SPRINT_3800_0002_0003 (Gateway), SPRINT_3800_0002_0004 (IaC)
|
||||
|
||||
## Documentation Prerequisites

|
||||
### File Location
|
||||
|
||||
```
|
||||
src/Scanner/__Libraries/StellaOps.Scanner.Reachability/Boundary/
|
||||
K8sBoundaryExtractor.cs [NEW]
|
||||
```
|
||||
|
||||
### Interface
|
||||
|
||||
K8sBoundaryExtractor implements IBoundaryProofExtractor with priority 200 (higher than RichGraphBoundaryExtractor's 100).
|
||||
|
||||
### K8s Resource Parsing
|
||||
|
||||
**Ingress Detection:**
|
||||
- Presence of Ingress resource → `isInternetFacing = true`
|
||||
- TLS configuration → `auth.mechanisms += "tls"`
|
||||
- Annotations for auth (nginx.ingress.kubernetes.io/auth-*) → auth details
|
||||
|
||||
**Service Detection:**
|
||||
- `type: LoadBalancer` → `exposure = "internet"`
|
||||
- `type: NodePort` → `exposure = "cluster_external"`
|
||||
- `type: ClusterIP` → `exposure = "cluster_internal"`
|
||||
|
||||
**NetworkPolicy Detection:**
|
||||
- Ingress rules → `controls += "network_policy"`
|
||||
- Egress rules → additional control evidence
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [x] K8sBoundaryExtractor.cs created and implements IBoundaryProofExtractor
|
||||
- [x] Correctly detects Ingress internet exposure
|
||||
- [x] Correctly detects Service exposure level
|
||||
- [x] Correctly parses NetworkPolicy controls
|
||||
- [x] Priority 200 (above base extractor)
|
||||
- [x] CanHandle returns true when context.Source == "k8s"
|
||||
- [x] Unit tests cover all K8s resource scenarios
|
||||
- [x] Registered in DI via BoundaryServiceCollectionExtensions

||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Parse annotations | K8s annotations contain auth/TLS hints |

| Priority 200 | Higher than base (100) but lower than runtime (300) |
|
||||
|
||||
| Risk | Mitigation |

||||
|------|------------|
|
||||
| Complex K8s manifests | Focus on common patterns first |
|
||||
| Annotation variations | Support nginx, traefik, istio annotations |

# SPRINT_3800_0003_0002 - Evidence TTL/Staleness Handling
|
||||
|
||||
## Overview
|
||||
|
||||
Implement TTL (Time-To-Live) and staleness handling for evidence responses. This ensures that evidence freshness is tracked and stale evidence triggers appropriate warnings or re-computation.
|
||||
|
||||
**Master Plan:** `SPRINT_3800_0000_0000_explainable_triage_master.md`
|
||||
**Working Directory:** `src/Scanner/StellaOps.Scanner.WebService/`
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Add `expires_at` timestamp to evidence responses based on VEX timestamp + policy TTL
|
||||
- Implement staleness detection in `EvidenceCompositionService`
|
||||
- Add `is_stale` flag to `FindingEvidenceResponse`
|
||||
- Create policy-based TTL configuration
|
||||
- Add warning/info headers when evidence is stale or near expiry
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream (DONE):**
|
||||
- SPRINT_3800_0003_0001: Evidence API Endpoint (FindingEvidenceResponse, EvidenceCompositionService)

|
||||
| Add unit tests for TTL logic | DONE | Agent | 4 unit tests for EvidenceCompositionOptions defaults and configuration |
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### TTL Policy Configuration
|
||||
|
||||
```csharp
|
||||
public sealed class EvidenceTtlOptions
|
||||
{
|
||||
public TimeSpan DefaultTtl { get; set; } = TimeSpan.FromDays(7);
|
||||
public TimeSpan VexTtl { get; set; } = TimeSpan.FromDays(30);
|
||||
public TimeSpan StaleWarningThreshold { get; set; } = TimeSpan.FromDays(1);
|
||||
}
|
||||
```
|
||||
|
||||
### Staleness Logic
|
||||
|
||||
1. Calculate `expires_at` from evidence timestamps + TTL:
|
||||
- Reachability: scan timestamp + DefaultTtl
|
||||
- VEX: VEX timestamp + VexTtl
|
||||
- Use minimum of all evidence expiry times
|
||||
|
||||
2. Set `is_stale = true` when `expires_at < now`
|
||||
|
||||
3. Add `X-Evidence-Warning: stale` header when stale
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [x] Evidence responses include `expires_at` timestamp
|
||||
- [x] Evidence responses include `is_stale` boolean
|
||||
- [x] Stale evidence returns 200 OK with warning header
|
||||
- [x] TTL values configurable via options
|
||||
- [x] Unit tests cover TTL calculation edge cases
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Use minimum expiry | Evidence chain is only as fresh as oldest component |
|
||||
| Return stale data with warning | Don't fail requests; let consumers decide |
|
||||
| Separate VEX TTL | VEX decisions have longer validity than scan data |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Clock skew | Use UTC everywhere; document tolerance |
|
||||
| Stale VEX ignored | UI must display staleness clearly |
|
||||
|
||||

- [x] DI registration added
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| DSSE format | Standard for attestations, compatible with Sigstore |
|
||||
| in-toto predicate | Well-defined predicate structure for policy decisions |
|
||||
| Evidence refs as subjects | Enable verification chain back to source evidence |
|
||||
| In-memory attestation store | Simplified implementation; production uses persistent storage |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Signing key management | Defer to Attestor module for actual signing |
|
||||
| Large attestation size | Limit to essential evidence refs |
|
||||
| K8sBoundaryExtractor pre-existing errors | BLOCKED: Sprint 3800_0002_0002 has incomplete implementation causing build failure. Does not affect attestation code. |

| `broken` | Chain link missing or digest mismatch |
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [x] `IAttestationChainVerifier` interface defined
|
||||
- [x] `AttestationChainVerifier` verifies chain integrity
|
||||
- [x] Chain model captures all attestation types
|

- [x] Verification status reported for each attestation
|
||||
- [x] Chain expiration handled (earliest TTL)
|
||||
- [x] Unit tests cover all verification scenarios
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Lazy loading | Fetch attestations on-demand rather than preloading |
|
||||
| Digest comparison | Verify subject digests match across chain links |
|
||||
| Status enum | Clear verification status for UI display |
|
||||
| Offline support | Verification works without network access |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Missing attestations | Report partial status rather than failing |
|
||||
| Clock drift | Use expiry timestamps with grace period |
|
||||
| Large chains | Limit chain depth in initial implementation |
|
||||
|
||||

|
||||
CertificateValidationResult ValidateCertificateChain(
|
||||
X509Certificate2 certificate,
|
||||
TrustRootBundle trustRoots);
|
||||
}
|
||||
```
|
||||
|
||||
#### TrustRootBundle
|
||||
```csharp
|
||||
public sealed record TrustRootBundle
|
||||
{

||||
public required DateTimeOffset BundleExpiresAt { get; init; }
|
||||
public string? BundleDigest { get; init; }
|
||||
}

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Bundle-based trust | Enables true air-gap operation |
|
||||
| No CRL/OCSP calls | Revocation via bundle refresh |
|
||||
| Time-bounded bundles | Security via periodic refresh |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Stale trust roots | Bundle expiry enforcement |
|
||||
| Missing intermediates | Include full chain in bundle |
|
||||
| Clock skew | Use bundle timestamp as reference |

||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Standalone components | Angular v17 best practice, tree-shakeable |
|
||||
| Material Design chips | Consistent with existing UI patterns |
|
||||
| Color coding | Intuitive visual indicators for security state |
|

|
||||
- **Reachability Tab**: Path visualization with confidence tier and gates
|
||||
- **VEX Tab**: VEX decisions with merge status, justifications, jurisdictions
|
||||
- **Attestation Tab**: DSSE/in-toto envelope details, verification status, Rekor references
|
||||
|
||||
### Key Features
|
||||
|
||||

||||
- **Missing**: ○ Gray - Required but not present
|
||||
- **Pending**: ○ Blue - Optional, awaiting action
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [ ] Chain viewer displays all attestation types
|
||||
- [ ] Each node shows digest, predicate type, signer
|
||||
- [ ] Verification status clearly indicated
|
||||
- [ ] Click to expand shows DSSE envelope JSON
|
||||
- [ ] Rekor references open in new tab
|
||||
- [ ] Chain status computed from individual nodes
|
||||
- [ ] Missing nodes highlighted as gaps
|
||||
- [ ] Keyboard accessible (arrow navigation)

||||
- [ ] ARIA: Proper roles for list/items
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |

|
||||
| Horizontal layout | Natural left-to-right flow for chain |
|
||||
| Collapse by default | Avoid overwhelming with JSON |
|
||||
| Optional approval node | May not exist yet |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Many attestation refs | Group by type, show count |
|
||||
| Long digests | Truncate with copy button |

## Implementation Details
|
||||
|
||||
### Component Specification
|
||||
|
||||
#### ApprovalButtonComponent
|
||||
```typescript
|
||||
@Component({
|
||||
selector: 'stella-approval-button',
|
||||
standalone: true,
|
||||
})
|
||||
export class ApprovalButtonComponent {
|
||||
// Inputs
|
||||
findingId = input.required<string>();
|
||||
digestRef = input.required<string>();
|
||||
chainStatus = input<ChainStatusDisplay>('empty');
|
||||
missingAttestations = input<string[]>([]);
|
||||
loading = input<boolean>(false);
|
||||
disabled = input<boolean>(false);
|
||||
|
||||
// Outputs
|
||||
approve = output<ApprovalRequest>();
|
||||
|
||||
// State
|
||||
canApprove = computed(() =>
|
||||
this.chainStatus() === 'complete' && !this.disabled()
|
||||
);
|
||||
|
||||
// Display: disabled with tooltip when chain incomplete
|
||||
// Shows checkmark or spinner based on state
|
||||
// Opens modal for reason on click
|
||||
}
|
||||
```
|
||||
|
||||
### Approval Request Model
|
||||
```typescript
|
||||
interface ApprovalRequest {
|
||||
findingId: string;
|
||||
digestRef: string;
|
||||
reason: string;
|
||||
expiresIn?: number; // days, default 30
|
||||
}
|
||||
```

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Require reason | Audit trail, compliance |
|
||||
| 30-day default expiry | Consistent with HumanApprovalAttestationService |
|
||||
| Modal confirmation | Prevent accidental approvals |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| User closes modal during API call | Disable close during submission |
|
||||
| Chain becomes invalid after load | Re-validate before submit |
|
||||
|
||||
## Effort Estimate
|
||||
|
||||
**Size:** Medium (M) - 2-3 days

||||
|
||||
### Component Specifications
|
||||
|
||||
#### MetricsDashboardComponent
|
||||
```typescript
|
||||
@Component({
|
||||
selector: 'stella-metrics-dashboard',
|
||||
standalone: true,
|
||||
})
|
||||
export class MetricsDashboardComponent {

// Filter state
|
||||
severityFilter = signal<string[]>(['critical', 'high', 'medium', 'low']);
|
||||
statusFilter = signal<string[]>(['pending', 'approved', 'blocked']);
|
||||
|
||||
// Computed metrics
|

```
|
||||
|
||||
### Key Metrics
|
||||
|
||||
1. **Coverage Rate** - % of findings with complete attestation chains
|
||||
2. **Approval Velocity** - Approvals per day/week
|
||||
3. **Mean Time to Approve** - Average time from finding to approval
|
||||
4. **Gap Analysis** - Findings missing required attestations
|
||||
|
||||
### Acceptance Criteria (from master plan)
|
||||
|
||||
- [ ] % changes with complete attestations target >= 95%
|
||||
- [ ] TTFE (time-to-first-evidence) target <= 30s
|
||||
- [ ] Post-deploy reversions due to missing proof trend to zero
|
||||

||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Client-side computation | MVP simplicity, move to API later |
|
||||
| Bar chart for coverage | Clear visual indicator |
|
||||
| Line chart for velocity | Show trends over time |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Large dataset performance | Pagination, aggregation |
|
||||
| Missing historical data | Show available range only |
|
||||
|
||||
