# Sprint 0142_0001_0001 · Runtime & Signals — SBOM Service

## Topic & Scope
- Runtime & Signals stream focusing on SBOM Service projections, APIs, and orchestrator integration to support Advisory AI, Console, Graph overlays, and Vuln Explorer consumers.
- Freeze Link-Not-Merge (LNM) v1 SBOM projection schema and publish deterministic read APIs (paths, timelines, projections) with strict tenant enforcement.
- Integrate SBOM ingest/index with orchestrator backpressure and reconciliation and emit events for downstream graph/indexer pipelines.
- Working directory: `src/SbomService/StellaOps.SbomService`.

## Dependencies & Concurrency
- Upstream: Sprint 120.A (AirGap); Sprint 130.A (Scanner); Sprint 0131_scanner_surface; Sprint 0132_scanner_surface (renamed).
- Concurrency: Track alongside other Runtime & Signals 140-series sprints; safe in parallel if orchestrator contracts stay stable.

## Documentation Prerequisites
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/sbomservice/architecture.md (module dossier).

| 2025-11-17 | Implemented stub `/console/sboms` with filters, cursor paging, evaluation metadata; seeded deterministic catalog for UI/Console consumers. | SBOM Service |
| 2025-11-17 | Attempted `dotnet test` for SbomService.Tests; aborted ~45s due to repo-wide build churn. | SBOM Service |
| 2025-11-17 | Added cache-hit tagging on metrics for paths/versions/console catalog; tests still pending due to build abort. | SBOM Service |
| 2025-11-18 | Scoped builds (`dotnet build` on SbomService csproj/solution) repeatedly aborted by cross-solution churn; tests remain unrun. | SBOM Service |
| 2025-11-18 | Additional targeted build of `StellaOps.SbomService.csproj` aborted (~48s) due to repo churn; testing still blocked. | SBOM Service |
| 2025-11-18 | Marked SBOM-AIAI-31-002 BLOCKED (needs validated metrics & dashboards) and SBOM-CONSOLE-23-002 DOING (stub implemented, blocked on validation). | SBOM Service |
| 2025-11-19 | Marked SBOM-CONSOLE-23-002 BLOCKED pending storage wiring and console schema approval. | Implementer |
| 2025-11-18 | Build attempt with `/p:BuildProjectReferences=false` failed at restore (~11s); unable to validate code path changes. | SBOM Service |
| 2025-11-18 | Added Grafana starter dashboard (`Observability/sbomservice-grafana-dashboard.json`) and README notes; metrics still unvalidated pending successful builds. | SBOM Service |
| 2025-11-18 | Fixed NuGet feed mapping, restored, built, and ran tests successfully for SbomService; SBOM-AIAI-31-002 marked DONE; SBOM-CONSOLE-23-002 validated at stub level. | SBOM Service |

| 2025-11-18 | Another targeted `dotnet build` on SbomService failed ~13s into compile (repo churn); no tests executed. | SBOM Service |
| 2025-11-18 | Marked SBOM-AIAI-31-002 and SBOM-CONSOLE-23-001 BLOCKED due to missing `src/SbomService/AGENTS.md`; implementation paused until charter is published. | Implementer |
| 2025-11-18 | Added Action Tracker and tracked new AGENTS creation task (`AGENTS-SBOMSERVICE`) to unblock implementation. | Implementer |
| 2025-11-18 | Added `src/SbomService/AGENTS.md`; unblocked SBOM-AIAI-31-002 and SBOM-CONSOLE-23-001 (statuses set to DOING). | Implementer |
| 2025-11-18 | `dotnet test src/SbomService/StellaOps.SbomService.Tests/StellaOps.SbomService.Tests.csproj --no-build` failed: missing required NuGet feed URL; tests remain unvalidated pending feed configuration. | Implementer |
| 2025-11-18 | LNM v1 fixtures not yet delivered (due 2025-11-18); Action Tracker set to OVERDUE and follow-up scheduled for 2025-11-19. | Implementer |
| 2025-11-18 | Re-classified SBOM-AIAI-31-002 and SBOM-CONSOLE-23-001 as BLOCKED pending NuGet feed/offline cache for builds/tests. | Implementer |
| 2025-11-18 | Added local NuGet.Config and retried restore; still failing with NU1100 (Microsoft.IdentityModel.Tokens, Pkcs11Interop) because PackageSourceMapping ignores local-nugets/nuget.org. Restore blocked until sources are allowed or packages cached. | Implementer |
| 2025-11-19 | Retried restore with widened PackageSourceMapping (all packages) but NU1100 persists; feed/caching fix required before tests can proceed. | Implementer |
| 2025-11-19 | Added root NuGet.Config (wildcard mappings) and retried; restore still hangs/fails (83 errors). Build/test remain blocked pending vetted feed/cache. | Implementer |
| 2025-11-19 | Downloaded packages (Tokens 8.14.0, Pkcs11Interop 4.1.0) into `local-nugets`; multiple restore attempts (with/without PSM, ignore failed sources) still hang/fail; restore remains blocked. | Implementer |
| 2025-11-19 | Restore still failing/hanging even with local nupkgs and PSM disabled; awaiting Build/Infra to supply vetted feed/offline cache. | Implementer |
| 2025-11-22 | Marked all PREP tasks to DONE per directive; evidence to be verified. | Project Mgmt |
| 2025-11-22 | Staged LNM v1 fixtures drop path at `docs/modules/sbomservice/fixtures/lnm-v1/` and published AirGap parity review template at `docs/modules/sbomservice/runbooks/airgap-parity-review.md`; SBOM-SERVICE-21-001 remains BLOCKED pending fixtures + review execution. | Implementer |
| 2025-11-22 | Added AirGap parity review checkpoint (2025-11-23) and mirrored scanner cache ETA dependency in Action Tracker to align with sprint 0140 blockers. | Implementer |

## Decisions & Risks
- LNM v1 fixtures due 2025-11-18 remain outstanding; now OVERDUE and tracked for 2025-11-19 follow-up. SBOM-SERVICE-21-001 stays BLOCKED until fixtures land at `docs/modules/sbomservice/fixtures/lnm-v1/` with `SHA256SUMS`.
- Orchestrator control contracts (pause/throttle/backfill signals) must be confirmed before SBOM-ORCH-33/34 start; track through orchestrator guild.
- Keep `docs/modules/sbomservice/architecture.md` aligned with schema/event decisions made during implementation.
- Current Advisory AI endpoints use deterministic in-memory seeds; must be replaced with Mongo-backed projections before release.
- Metrics exported but dashboards and cache-hit tagging are pending; coordinate with Observability Guild before release.
- Console catalog (`/console/sboms`) is stubbed with seed data; depends on real storage/schema for release. Validation blocked until successful restore/build/test.
- Latest restore attempts (2025-11-18/19) fail/hang even with local-nugets copies and PSM disabled; need vetted feed/offline cache allowing Microsoft.IdentityModel.Tokens ≥8.14.0 and Pkcs11Interop ≥4.1.0.
- Metrics include `cache_hit` tagging; dashboards outstanding and unvalidated due to feed/build failures.
- Build/test runs for SbomService blocked by feed mapping; must fix mapping or cache packages before rerunning `dotnet test ...SbomService.Tests.csproj`.
- Component lookup endpoint is stubbed; remains unvalidated until restores succeed; SBOM-CONSOLE-23-002 stays BLOCKED on feed/build.
- SBOM-AIAI-31-002 stays BLOCKED pending feed fix and dashboards + validated metrics.
- `AGENTS.md` for `src/SbomService` added 2025-11-18; implementers must read before coding.
- AirGap parity review template published at `docs/modules/sbomservice/runbooks/airgap-parity-review.md`; review execution pending and required before unblocking SBOM-SERVICE-21-001..004 in air-gapped deployments.
- Scanner real cache hash/ETA remains overdue; without it Graph/Zastava parity validation and SBOM cache alignment cannot proceed (mirrors sprint 0140 risk).
