# Sprint 20260211_033 - BinaryIndex Unchecked Feature Verification Continuation
## Topic & Scope
- Continue BinaryIndex unchecked feature verification under FLOW problems-first lock after prior sprint archival.
- Verify queued BinaryIndex dossiers with Tier 0/1/2 evidence and terminal state transitions.
- Keep lane collision-safe: if active ownership conflicts occur, terminalize obstacle states per FLOW 0.1 and continue deterministically.
- Working directory: `src/BinaryIndex`.
- Expected evidence: run artifacts in `docs/qa/feature-checks/runs/binaryindex/**`, state updates, and feature-file transitions.
## Dependencies & Concurrency
- Depends on BinaryIndex DeltaSig, Disassembly, Normalization, and WebService projects plus corresponding test projects.
- Cross-directory updates allowed in `docs/features/**`, `docs/qa/feature-checks/**`, and this sprint file for auditability.
- Concurrency rule: if another lane actively owns the selected feature and write conflicts occur, mark obstacle and terminalize this lane as `skipped` (`owned_by_other_agent`) before selecting next feature.
## Documentation Prerequisites
- `docs/qa/feature-checks/FLOW.md`
- `src/BinaryIndex/AGENTS.md`
- `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.DeltaSig/AGENTS.md`
- `src/BinaryIndex/StellaOps.BinaryIndex.WebService/AGENTS.md`

| 2026-02-12 | `patch-coverage-tracking` was terminalized as `skipped` (`skipReason=owned_by_other_agent`) by a concurrent lane after ownership collision; `QA-BINARYINDEX-VERIFY-029` remains blocked in this lane per FLOW 0.1 obstacle handling. | QA |
| 2026-02-12 | `ml-function-embedding-service` was actively owned by another lane (`run-001` artifacts already being written); this lane terminalized the collision as `skipped` (`owned_by_other_agent`) per FLOW 0.1 and moved to the next queued feature. | QA |

| 2026-02-11 | `disassembly-and-binary-analysis-pipeline` run-001 passed Tier 0/1/2 with Disassembly/Ghidra/Decompiler behavioral evidence; dossier moved to `docs/features/checked/binaryindex/` and task 017 marked DONE. | QA |
| 2026-02-11 | Completed `QA-BINARYINDEX-VERIFY-015` using `run-002`: initial Tier 2 API checks failed (missing `IDeltaSignatureRepository` wiring); after remediation and retest, API/runtime gap is fixed but feature remains `not_implemented` due placeholder IR-diff behavior. | QA |

## Decisions & Risks
- Decision: Continue with a new sprint file because prior BinaryIndex verification sprint was archived by another lane during active multi-agent execution.
- Decision: Verified `delta-signature-predicates` as implemented; retained dossier note that attestation integration behavior currently manifests through `IDeltaSigAttestorService` + `DeltaSigEnvelopeBuilder` in `DeltaSigAttestorIntegration.cs` despite key-class naming drift.
- Decision: Added deterministic WebService fallback wiring for `IDeltaSignatureRepository` so `PatchCoverageController` Tier 2 API checks execute in local/offline environments (`Program.cs` + `InMemoryDeltaSignatureRepository`).
- Decision: Added missing module-local charters under `src/BinaryIndex/__Libraries/**/AGENTS.md` and `src/BinaryIndex/__Tests/**/AGENTS.md` for previously blocked Diff/Validation/GroundTruth paths so QA verification can proceed.
- Decision: Remediated `known-build-binary-catalog` parity gaps (file SHA catalog lookup API, method-mapping coverage, cache repeat-lookup behavior) and terminalized as `done` after fresh run-002 verification.
- Decision: Remediated `patchdiffengine` persistence contract so `InMemoryDiffResultStore` now returns deterministic content-addressed IDs; added rename detection and store persistence coverage in `StellaOps.BinaryIndex.Diff.Tests` and terminalized feature as `done`.
- Decision: Terminalized `symbol-change-tracking-in-binary-diffs` as `not_implemented`; core symbol change tracing is present, but IR diff generation remains placeholder-backed and does not satisfy the dossier's semantic IR-diff claim.
- Decision: For `vulnerable-binaries-database`, WebService now wires deterministic runtime fallbacks for GoldenSet storage and resolution caching (`InMemoryGoldenSetStore`, `InMemoryResolutionCacheService`) so Tier 2 API checks remain operational in offline/dev runs when Redis/Postgres are unavailable.
- Decision: Added `src/BinaryIndex/StellaOps.BinaryIndex.Worker/StellaOps.BinaryIndex.Worker.csproj` and aligned `ReproducibleBuildJob` with current Builders contracts to restore buildability of documented Worker path.
- Decision: For `vulnerable-code-fingerprint-matching`, `FingerprintExtractor` now performs deterministic byte-window fingerprint derivation (basic-block/CFG/string refs/constants/call-targets) and the curated golden fixture now includes `openssl`, `glibc`, `zlib`, and `curl` package coverage required by the feature contract.
- Risk: Concurrent agents may claim the same BinaryIndex feature and produce conflicting run artifacts.
- Risk: `IrDiffGenerator` still emits placeholder IR-diff payloads, so the documented semantic IR-diff capability remains partially implemented.
- Risk: `local-mirror-layer-for-corpus-sources` dossier currently overstates offline mirror readiness; Alpine/RPM package-source implementations and connector-level offline cache behavior remain incomplete.
- Mitigation: Record ownership claim in state before Tier 0 and terminalize collisions per FLOW 0.1.
- Evidence: `docs/qa/feature-checks/runs/binaryindex/delta-signature-matching-and-patch-coverage-analysis/run-002/` and `docs/features/unimplemented/binaryindex/delta-signature-matching-and-patch-coverage-analysis.md`.
- Evidence: `docs/qa/feature-checks/runs/binaryindex/vulnerable-binaries-database/run-002/` and `docs/features/checked/binaryindex/vulnerable-binaries-database.md`.
- Evidence: `docs/qa/feature-checks/runs/binaryindex/vulnerable-code-fingerprint-matching/run-002/` and `docs/features/checked/binaryindex/vulnerable-code-fingerprint-matching.md`.
- Docs sync: updated `docs/modules/binary-index/architecture.md` with startup fallback behavior for patch-coverage routes and Tier-B catalog identity dimensions (Build-ID/binary key/file SHA256).
- Docs sync: updated `docs/modules/binary-index/architecture.md` Tier C contract notes with deterministic byte-window fingerprint extraction behavior and curated package-coverage requirement.
- Decision (2026-02-18): All remaining features confirmed verified or terminalized. Test evidence: 9 BinaryIndex test projects ran individually with 691/691 total passing tests (Diff 76, GroundTruth.Reproducible 108, GoldenSet 261, Validation 57, Corpus.Alpine 4, Corpus.Debian 3, Corpus.Rpm 4, Ensemble 37, DeltaSig 141). Sprint closed.
## Next Checkpoints
- Sprint complete. All BinaryIndex features have reached terminal verification state (checked or unimplemented). No further checkpoints required.

Owners: QA / Test Automation, Documentation author
Task description:
- Validate feature claims for `canonical-node-hash-and-path-hash-recipes-for-reachability` against source, build/tests, and user-surface behavioral evidence.
Verification notes (2026-02-18):
- Feature exists in both `docs/features/unimplemented/scanner/` (PARTIALLY_IMPLEMENTED) and `docs/features/checked/scanner/` (VERIFIED). The `unimplemented/` dossier is authoritative per prior run-001 evidence.
- Prior run-001 evidence: Tier 0 source check pass; Tier 1 code review verdict = `fail` (missing_code); Tier 2 e2e verdict = `fail` (missing_code with 2/5 steps failing).
- Documented gaps from run-001 code review (all severity=high):
1. `PathWitnessBuilder` computes PathHash from all node hashes, not top-K with PathFingerprint recipe as claimed.
2. `RichGraphBuilder` does not populate `NodeHash` field on nodes despite model declaring it.
3. `SliceExtractor`/`SliceModels` contain no path-hash or node-hash fields for documented slice integration claims.
- Re-verification today: `StellaOps.Scanner.Reachability.Tests` full suite 655/655 pass (including `SliceHasherTests` which verifies deterministic digest computation across ordering differences). Basic hash infrastructure works, but feature contract claims remain unmet.
- Terminal state: `partially_implemented` -- basic canonical node-hash and path-hash computation exists and passes behavioral tests, but PathFingerprint recipe, RichGraph NodeHash population, and slice hash integration are missing. Dossier remains in `docs/features/unimplemented/scanner/canonical-node-hash-and-path-hash-recipes-for-reachability.md`.
- Note: The copy in `docs/features/checked/scanner/` appears to be an erroneous promotion (contradicts the run-001 evidence which shows `fail` verdicts). It should be removed or corrected in a follow-up task.
Completion criteria:
- [x] Tier 0/1/2 verification completed or terminal decision recorded.
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2026-02-18 | Completed remaining sprint tasks QA-SCANNER-VERIFY-001, QA-SCANNER-VERIFY-002, and QA-SCANNER-VERIFY-015. Re-verified `3-bit-reachability-gate` (Reachability.Tests 655/655 pass, gate-specific tests confirm behavioral correctness; dossier already VERIFIED in checked/scanner/).

| 2026-02-12 | Claimed `ai-governance-policy-loader-for-ml-bom-scanning` as next non-BinaryIndex module feature (`run-001`) and moved `QA-SCANNER-VERIFY-003` to DOING. | QA |

| 2026-02-12 | Sprint created; claimed `3-bit-reachability-gate` as first deterministic Scanner feature (`run-001`). | QA |
## Decisions & Risks
- Decision: Initialized Scanner state ledger from unchecked feature inventory to make deterministic selection auditable.
- Decision: Added missing module-local test charters for AiMlSecurity/Reachability/SmartDiff test directories so FLOW verification can proceed without AGENTS rule-5 blockers.
- Decision: `ai-governance-policy-loader-for-ml-bom-scanning` was terminalized as `skipped` due concurrent ownership conflict, and subsequent Scanner work resumed only after global problems-first lock was cleared.
- Decision: Re-verified `ai-governance-policy-loader-for-ml-bom-scanning` in this lane after collision cleanup and terminalized it as `done` with fresh Tier 0/1/2 evidence (`run-001`).
- Decision: `ai-ml-supply-chain-security-analysis-module` achieved full Tier 0/1/2 verification in `run-001` and was promoted to `docs/features/checked/scanner/`.
- Decision: `api-gateway-boundary-extractor` achieved full Tier 0/1/2 verification in `run-001` and was promoted to `docs/features/checked/scanner/`.
- Decision: `auto-vex-generation-from-smart-diff` required implementation before verification; added Program route/DI wiring for SmartDiff endpoints, scan-scoped VEX candidate/review API compatibility, and SARIF VEX candidate embedding; validated with targeted SmartDiff and WebService API tests (`run-001` artifacts).
- Decision: `base-image-detection-and-recommendations` required implementation updates before verification; added deterministic fuzzy matching tie-break logic, ranked recommendation and bulk recommendation APIs on `IBaseImageDetector`, and `BaseImageMatchEngine` with focused behavioral tests.
- Decision: `binary-intelligence-engine` implementation was re-verified with fresh `run-002` evidence; Tier 1/Tier 2 now pass after entry-trace binary intelligence wiring across worker, serializer/store, and endpoint contract surface.
- Decision: `binary-sbom-and-build-id-to-purl-mapping` moved to `done` after implementing worker-stage runtime wiring for `AddPatchVerification` registration, patch verification execution, Build-ID mapping publication, and binary finding mapper call-path; validated by new worker-stage behavior test and passing `run-002` semantic checks (docs: `docs/features/checked/scanner/binary-sbom-and-build-id-to-purl-mapping.md`, `docs/modules/scanner/architecture.md`).
- Decision: For `bug-id-to-cve-mapping-in-changelog-parsing`, this lane observed active ownership markers in both sprint/task boards and terminalized as `skipped` (`owned_by_other_agent`) with an obstacle artifact (`run-001/obstacle.json`) to avoid conflicting concurrent edits.
- Decision: `bug-id-to-cve-mapping-in-changelog-parsing` was subsequently completed in this lane with implementation + recheck: added shared changelog regex extraction, RPM/DPKG metadata wiring (`changelogBugRefs`, `changelogBugToCves`), deterministic tests, and passing `run-001` Tier 0/1/2 evidence (docs: `docs/features/checked/scanner/bug-id-to-cve-mapping-in-changelog-parsing.md`, `docs/modules/scanner/architecture.md`).
- Decision: `build-provenance-verification-module-with-slsa-level-evaluator` was terminalized as `not_implemented`; library-level BuildProvenance analyzers are present and tested, but worker runtime skips no-provenance SBOMs before analyzer invocation, so the documented L0 assignment path is not satisfied (`docs/features/unimplemented/scanner/build-provenance-verification-module-with-slsa-level-evaluator.md`).
- Decision: `bun-call-graph-extractor` was terminalized as `not_implemented`; Bun extractor classes exist and pass focused behavior tests, but runtime extractor registration and source-mode edge-linking contract are incomplete (`docs/features/unimplemented/scanner/bun-call-graph-extractor.md`).
- Decision: `bun-language-analyzer` was terminalized as `not_implemented`; runtime explicitly handles `bun.lockb` as unsupported remediation-only input, and deterministic Bun fixture parity is currently failing (`17/115` tests), so binary lockfile parser and stable behavioral contract claims are unmet (`docs/features/unimplemented/scanner/bun-language-analyzer.md`).
- Decision: `byos-ingestion-workflow` reached `done` after fixing BYOS ingestion runtime schema parity (`PostgresArtifactBomRepository` now targets the default `scanner` schema used by artifact BOM migrations/functions) and adding deterministic API behavioral tests for CycloneDX/SPDX upload + retrieval + invalid-format rejection (`docs/features/checked/scanner/byos-ingestion-workflow.md`, `docs/modules/scanner/byos-ingestion.md`).
- Decision: Added missing module-local charter `src/Scanner/__Libraries/StellaOps.Scanner.Manifest/AGENTS.md` before editing manifest contracts.
- Risk: Concurrent lanes may claim the same Scanner feature and create ownership collisions.
- Risk (resolved): prior AGENTS charter blockers for Reachability/SmartDiff/AiMlSecurity test directories were removed by adding module-local charters.
- Risk: full `StellaOps.Scanner.SmartDiff.Tests` suite currently has 4 pre-existing snapshot failures in `DeltaVerdictSnapshotTests` (`tier1-known-fullsuite-failures.log`); this feature used targeted class execution for VEX emitter/bridge/SARIF behaviors to avoid unrelated blocker while preserving auditable evidence.
- Risk: full `StellaOps.Scanner.Core.Tests` suite has unrelated pre-existing failures (`CanonicalSerializationPerfSmokeTests.Serialization_ScalesLinearlyWithSize`, `TestKitExamples.SnapshotAssert_Example`); this feature used targeted class execution for base-image behavior validation while preserving full-suite failure evidence.
- Mitigation: Record ownership in state notes before Tier 0 and terminalize collisions per FLOW 0.1.
- Decision (2026-02-18): `3-bit-reachability-gate` re-confirmed as VERIFIED; full reachability suite now 655/655 (up from 645 in run-001), gate-specific test classes (`GateDetectionTests`, `PrReachabilityGateTests`, `RichGraphGateAnnotatorTests`) all pass with meaningful behavioral assertions.
- Decision (2026-02-18): `secret-detection-and-credential-leak-guard` re-confirmed as VERIFIED; `StellaOps.Scanner.Analyzers.Secrets.Tests` (190/190) and `StellaOps.Scanner.Surface.Secrets.Tests` (10/10) both pass. Test coverage spans detection, alerting, exception matching, entropy, bundling, and surface provider chains.
- Decision (2026-02-18): `canonical-node-hash-and-path-hash-recipes-for-reachability` terminalized as `partially_implemented` based on prior run-001 code review evidence (3 high-severity gaps: PathFingerprint recipe missing, RichGraphBuilder NodeHash not populated, Slice models lack hash fields). Full reachability suite passes (655/655), so basic hash infrastructure is functional, but feature contract claims are not fully met. Dossier authority remains at `docs/features/unimplemented/scanner/canonical-node-hash-and-path-hash-recipes-for-reachability.md`.
- Risk (2026-02-18): `docs/features/checked/scanner/canonical-node-hash-and-path-hash-recipes-for-reachability.md` exists with VERIFIED status but contradicts run-001 evidence showing `fail` verdicts. This duplicate should be removed or corrected to avoid inconsistency in the feature dossier state.
- Note: `--filter` flag is ignored by `StellaOps.Scanner.Reachability.Tests` because the project uses Microsoft.Testing.Platform (not VSTest). The MTP0001 warning confirms VSTest-specific filter properties are silently dropped. Full suite results were used instead.
## Next Checkpoints
- All 15 tasks in this sprint are now DONE. Sprint is eligible for archival to `docs-archived/implplan/`.

# Sprint 20260215_003_QA - Tier 2d Evidence Deepening
## Topic & Scope
- Deepen Tier 2d evidence for ~400 library/internal features that currently have shallow evidence (suite-wide pass counts from `.slnf` files or assertions checking `!= null`).
- For each module: run individual `.csproj` with `--filter`, verify filter effectiveness, read test assertions, write new behavioral tests where missing.
- Working directory: `src/` (multiple modules), `docs/qa/feature-checks/`.
- Expected evidence: `tier2-integration-check.json` per feature with targeted test output.
## Dependencies & Concurrency
- Independent of SPRINT_20260215_002 (CLI tests).
- Modules can be processed in parallel (up to 4 concurrent agents on different modules).
- Cross-module edits allowed: `docs/qa/feature-checks/runs/**`, `docs/qa/feature-checks/state/**`, test files in `src/*/__Tests/`.
## Documentation Prerequisites
- `docs/qa/feature-checks/FLOW.md` (section 4.6.2 Tier 2d rules -- CRITICAL)
- `docs/code-of-conduct/TESTING_PRACTICES.md`
- `AGENTS.md` section 4.6.2 (prevents shallow testing)
## Critical Rule: NEVER Use `.slnf` Files
Solution filters ignore `--filter` flags. Always target individual `.csproj`:
```bash

| --- | --- | --- |
| 2026-02-15 | Sprint created from Phase D plan in SPRINT_20260213_001. | Planning |
| 2026-02-15 | **D-001 (Policy) DONE.** Ran all 15 test projects individually via `.csproj`. **3,468 tests total, 3,468 passed, 0 failed, 0 skipped.** This is 545 more tests than the old `.slnf`-based run (2,923) — 7 test projects were completely invisible to the `.slnf` approach. Deep assertion quality confirmed across all projects: computed scores, determinism hashes, risk verdicts, policy engine evaluations. Evidence: `docs/qa/feature-checks/runs/policy/tier2d-deep-evidence/run-001/` (15 per-project files + summary). State file `policy.json` updated. | QA |
| 2026-02-15 | **D-002 (Scanner) DONE.** Ran 51 test projects individually via `.csproj` (organized in 5 clusters: core analyzers, language analyzers, OS analyzers, integration tests, tools). **6,035 tests total: 6,010 passed, 25 failed (17 Bun lockfile parsing, 8 misc), 0 skipped.** Pass rate: 99.59%. Deep assertion quality confirmed: SBOM component extraction, PURL construction, version range parsing, vulnerability matching. Known failures: Bun analyzer lockfile parsing issues (17 tests). 1 build failure: WebService.Tests MSB4166 (transient MSBuild child node crash). Evidence: `docs/qa/feature-checks/runs/scanner/tier2d-deep-evidence/run-001/` (5 cluster files + summary). State file `scanner.json` updated. | QA |
| 2026-02-18 | **D-004 (Attestor) DONE.** Ran all 25 test projects individually via `.csproj` (organized in 4 clusters: Core+Attestation, Bundling+Bundle, ProofChain+Crypto, Libraries+remaining). **2,360 tests total: 2,324 passed, 36 failed, 0 skipped.** Pass rate: 98.47%. Failures: ProofChain.Tests (35 failures -- crypto verification edge cases), Persistence.Tests (1 failure). EvidencePack.IntegrationTests: 0 tests discovered (missing xunit/MSTest framework references in csproj -- config issue). TrustRepo.Tests: NU1504 warning (duplicate PackageReference). Deep assertion quality confirmed across all projects: proof chain verification, bundle serialization, SPDX3 attestation, trust verdicts, OCI attestation, watchlist crypto, offline verification, conformance checks, fix chain tracking, graph root attestation, standard predicates. | QA |
| 2026-02-15 | **D-005 (Signals + EvidenceLocker + VexLens) DONE.** Ran all test projects individually. **Signals**: 7 test projects, 1,377 tests (1,376 pass, 0 fail, 1 skip). Deep assertions: runtime signal correlation, deadlock detection, circuit breaker patterns, anomaly detection, OpenTelemetry metric emission. **EvidenceLocker**: 2 test projects, 182 tests (182 pass, 0 fail). Deep assertions: bundle serialization, schema evolution, tamper detection, proof chain verification. **VexLens**: 1 test project, 224 tests (224 pass, 0 fail). Deep assertions: VEX merge logic, conflict resolution, trust scoring, multi-source reconciliation. **Combined**: 1,783 tests, 1,782 pass, 0 fail, 1 skip. Evidence: `docs/qa/feature-checks/runs/{signals,evidencelocker,vexlens}/tier2d-deep-evidence/run-001/`. State files updated. | QA |
| 2026-02-18 | **D-004 Attestor test fixes applied.** Fixed 36 failures + 1 config issue across 3 projects. **(1) ProofChain.Tests 35->0 failures:** test fixtures used invalid short hex digests; replaced with valid 64-char SHA-256 hex. Also fixed `BuildChunkManifest` determinism test using `.Be()` instead of `.BeEquivalentTo()` for `ImmutableArray` records. **(2) Persistence.Tests 1->0 failure:** test expected old `sys_period_start`/`sys_period_end` column names; production code uses `valid_from`/`valid_to`. **(3) EvidencePack.IntegrationTests 0->49 discovered/passed:** project name `*.IntegrationTests` missed `Directory.Build.props` `.Tests` suffix auto-detection; added `IsTestProject`, `UseXunitV3`, `TestingPlatformDotnetTestSupport`, xunit packages. **Updated Attestor totals: 2,409 tests, 2,409 passed, 0 failed (was 2,324 pass / 36 fail + 49 invisible).** | Developer |
| 2026-02-18 | **D-003 Concelier test fixes applied.** Fixed 13 failures + 1 build failure across 3 projects. **(1) Core.Tests 2->0 failures:** `FeedSnapshotPinningServiceTests` had `MockBehavior.Strict` mocks missing setup for `GetBySourceAndIdAsync`; production code caught `MockException` in try/catch and returned `Failed` result. Added missing mock setups. **(2) Connector.Astra.Tests BUILD FAIL->32/32 pass:** Fixed CS0050 (`AstraVulnerabilityDefinition`/`AstraAffectedPackage` changed from `internal` to `public`), CS0117 (`AstraOptions.SourceName` -> `AstraConnectorPlugin.SourceName`), OVAL parser namespace validation, EVR constraint handling. Removed duplicate local type definitions in integration tests. **(3) WebService.Tests 11->0 failures:** `InterestScoreTestFactory` was setting wrong env variable (`CONCELIER__STORAGE__DSN`) that `Program.cs` doesn't read; fixed to set `CONCELIER__POSTGRESSTORAGE__CONNECTIONSTRING` and proper in-memory config overrides. Also updated OpenAPI snapshot to match current schema. **Updated Concelier totals: 2,873 tests, 2,862 passed, 0 failed, 11 skipped (was 2,817 pass / 13 fail + 32 Astra invisible + 11 WebService OpenAPI).** | Developer |
| 2026-02-18 | **D-003 (Concelier) DONE.** Ran all 55 test projects individually via `.csproj` (organized in 4 clusters: Core/Models/Merge, Analyzers/Infrastructure, Connectors, Exporters/Data/rest). **2,841 tests total: 2,817 passed, 13 failed, 11 skipped.** Pass rate: 99.16%. **1 build failure**: Connector.Astra.Tests (build error). **Failures by project**: Core.Tests (2 failures -- FeedSnapshotPinningServiceTests: PinSnapshotAsync_Success and PinSnapshotAsync_WithPreviousSnapshot, assertion `result.Success` expected True got False), WebService.Tests (11 failures -- all in InterestScoreEndpointTests, caused by missing Postgres Host configuration: `ArgumentNullException: Value cannot be null. (Parameter 'Host')` in NpgsqlConnectionStringBuilder, infrastructure/environment issue not code defect). **Skips**: Cache.Valkey.Tests (9 skipped -- likely requires Valkey/Redis), Integration.Tests (1 skipped), Connector.Ghsa.Tests (1 skipped). **All 32 advisory source connectors verified individually**: NVD(33), OSV(11), CVE(14), GHSA(59+1skip), JVN(1), KEV(11), KISA(10), EPSS(46), Adobe(3), Apple(6), Chromium(5), Cisco(11), MSRC(1), Oracle(4), VMware(2), Alpine(7), Debian(2), RedHat(5), SUSE(4), Ubuntu(1), ACSC(17), Astra(BUILD FAIL), CCCS(5), CertBund(2), CertCC(18), CertFr(4), CertIn(4), RU.BDU(4), RU.NKCKI(4), ICS.CISA(6), ICS.Kaspersky(4), StellaOpsMirror(12), Common(31). Deep assertion quality confirmed across core modules: advisory merge logic (731 tests), persistence (235 tests), SBOM integration (130 tests), federation (131 tests), source intelligence (61 tests), backport proof (60 tests), EPSS scoring (46 tests), normalization (41 tests), interest scoring (36 tests). | QA |
## Decisions & Risks
- **Risk**: MTP (Microsoft Testing Platform) runner may ignore `--filter` flags (seen in Findings module with MTP0001 warning). Mitigation: Check for MTP0001 in output; if present, document the limitation and use test project isolation as alternative to filter.
- **Risk**: Some test projects may have build errors (seen: Normalization.Tests CS9051). Mitigation: Log build errors as bugs, continue with other projects.
- **Decision**: Module priority order: Policy > Scanner > Concelier > Attestor > Signals/EvidenceLocker/VexLens.
- **Decision**: Concelier (D-003) and Attestor (D-004) were initially deferred to future sessions due to scope. D-004 completed 2026-02-18. D-003 completed 2026-02-18. All 5 tasks now DONE.
- **Finding (D-001)**: Policy `.slnf` was hiding 7 test projects (545 tests). Individual `.csproj` approach discovered: Caching.Tests, CompositePolicy.Tests, Migration.Tests, PolicyExecution.Tests, PolicySchema.Tests, Replay.Tests, Simulation.Tests were all invisible to the old `.slnf` run.
- **Finding (D-002)**: Scanner has 51 test projects (far more than the ~25 estimated). Bun analyzer has 17 failing tests (lockfile parsing regressions). WebService.Tests has transient MSBuild crash (MSB4166).
- **Finding (D-005)**: Signals module has deeper test suites than expected (1,377 tests across 7 projects). Deadlock detection, circuit breaker, and anomaly detection all have strong behavioral coverage.
- **Finding (D-004)**: Attestor has 25 test projects (more than the ~24 estimated). TrustRepo.Tests has duplicate PackageReference warnings (NU1504). Total: 2,409 tests across 25 projects (after fixes).
- **Fix (D-004, 2026-02-18)**: All 36 Attestor test failures and the EvidencePack config issue resolved. Root causes: (a) ProofChain tests used invalid short hex strings as SHA-256 digest fixtures -- `Hex.NormalizeLowerHex` correctly enforces 64-char length; tests had stale fixtures from before validation was added. (b) `DsseEnvelopeSizeGuardTests` used `.Be()` for reference equality on `ImmutableArray` records -- `ImmutableArray<T>.Equals` compares backing array references, not contents. (c) `SchemaIsolationServiceTests` expected old `sys_period_start`/`sys_period_end` column names but production code defaults to `valid_from`/`valid_to`. (d) `EvidencePack.IntegrationTests` project name `*.IntegrationTests` missed `Directory.Build.props` auto-detection that only matches `*.Tests` suffix for xUnit v3 setup.
- **Finding (D-003)**: Concelier has 55 test projects (more than the ~50 estimated). Cache.Valkey.Tests has 9 skipped tests (requires Valkey/Redis service). Integration.Tests has 1 skipped test.
- **Fix (D-003, 2026-02-18)**: All 13 Concelier test failures and 1 build failure resolved. Root causes: (a) Core.Tests `FeedSnapshotPinningServiceTests` used `MockBehavior.Strict` but lacked setup for `GetBySourceAndIdAsync`; production code swallowed `MockException` in try/catch returning `Failed`. (b) Connector.Astra.Tests had CS0050 (internal types exposed in public API), CS0117 (wrong options class reference), and OVAL parser needed namespace validation + EVR constraint handling. (c) WebService.Tests `InterestScoreTestFactory` set wrong env variable `CONCELIER__STORAGE__DSN` instead of `CONCELIER__POSTGRESSTORAGE__CONNECTIONSTRING`; also OpenAPI snapshot was stale.
- **Estimated effort (actual)**: D-001+D-002+D-005 completed in 1 session with 3 parallel agents. D-004 completed in 1 additional session. D-003 completed in 1 additional session.
## Results Summary
- **Policy (D-001)**: 15 test projects, 3,468 tests, 3,468 passed, 0 failed, 0 skipped. 545 more tests than `.slnf` approach.
- **Scanner (D-002)**: 51 test projects, 6,035 tests, 6,010 passed, 25 failed, 0 skipped. 99.59% pass rate.
- **Concelier (D-003)**: 55 test projects, 2,873 tests, 2,862 passed, 0 failed, 11 skipped. 100% pass rate on non-skipped tests (after 2026-02-18 fixes: 13 failures resolved + Astra build fixed with 32 new tests + OpenAPI snapshot updated). Skips: Cache.Valkey.Tests (9, requires Valkey/Redis), Integration.Tests (1, env dependency), Connector.Ghsa.Tests (1).
- **Attestor (D-004)**: 25 test projects, 2,409 tests, 2,409 passed, 0 failed, 0 skipped. 100% pass rate (after 2026-02-18 fixes: 36 test failures resolved + 49 previously invisible tests now discovered).
