+# Advisory AI Active Tasks — Sprint 111
 
-> 2025-11-02: AIAI-31-002 – SBOM context domain models finalized with limiter guards; retriever tests now cover flag toggles and path dedupe. Service client integration still pending with SBOM guild.
-> 2025-11-04: AIAI-31-002 – Introduced `SbomContextHttpClient`, DI helper (`AddSbomContext`), and HTTP-mapping tests; retriever wired to typed client with tenant header support and deterministic query construction.
+| ID | Status | Description | Last Update |
+|----|--------|-------------|-------------|
+| AIAI-31-008 | DONE (2025-11-08) | Package inference on-prem container, remote inference toggle, deployment manifests, and Offline Kit guidance. | Remote toggle + deployment docs merged during Sprint 110 close-out. |
+| AIAI-31-009 | DOING (2025-11-09) | Expand unit/property/perf tests, strengthen injection harness, and enforce deterministic caches. | Extending orchestrator + executor regression coverage and guardrail fixtures this sprint. |
 
-> 2025-11-02: AIAI-31-003 moved to DOING – starting deterministic tooling surface (version comparators & dependency analysis). Added semantic-version + EVR comparators and published toolset interface; awaiting downstream wiring.
-> 2025-11-04: AIAI-31-003 completed – toolset wired via DI/orchestrator, SBOM context client available, and unit coverage for compare/range/dependency analysis extended.
-
-> 2025-11-02: AIAI-31-004 started orchestration pipeline work – begin designing summary/conflict/remediation workflow (deterministic sequence + cache keys).
-> 2025-11-04: AIAI-31-004 DONE – orchestrator composes structured/vector/SBOM context with stable cache keys and metadata (env flags, blast radius, dependency metrics); unit coverage via `AdvisoryPipelineOrchestratorTests` keeps determinism enforced.
-
-> 2025-11-02: AIAI-31-004 orchestration prerequisites documented in docs/modules/advisory-ai/orchestration-pipeline.md (task breakdown 004A/004B/004C).
-> 2025-11-04: AIAI-31-004A DONE – WebService `/v1/advisory-ai/pipeline/*` + batch endpoints enqueue plans with rate limiting & scope headers, Worker drains filesystem queue, metrics/logging added, docs updated. Tests: `dotnet test src/AdvisoryAI/__Tests/StellaOps.AdvisoryAI.Tests/StellaOps.AdvisoryAI.Tests.csproj --no-restore`.
-
-> 2025-11-04: AIAI-31-005 DONE – guardrail pipeline redacts secrets, enforces citation/injection policies, emits block counters, and tests (`AdvisoryGuardrailPipelineTests`) cover redaction + citation validation.
-
-> 2025-11-04: AIAI-31-006 DONE – REST endpoints enforce header scopes, apply token bucket rate limiting, sanitize prompts via guardrails, and queue execution with cached metadata. Tests executed via `dotnet test src/AdvisoryAI/__Tests/StellaOps.AdvisoryAI.Tests/StellaOps.AdvisoryAI.Tests.csproj --no-restore`.
-> 2025-11-06: AIAI-31-004B/C – Resuming prompt/cache hardening and CLI integration; first focus on backend client wiring and deterministic CLI outputs before full suite.
-> 2025-11-06: AIAI-31-004B/C DONE – Advisory AI Mongo integration validated, backend client + CLI `advise run` wired, deterministic console renderer with provenance/guardrail display added, docs refreshed, and targeted CLI tests executed.
-> 2025-11-08: AIAI-31-009 DONE – Added prompt-injection harness, dual golden prompts (summary/conflict), cache determinism/property tests, partial citation telemetry coverage, and plan-cache expiry refresh validation; `dotnet test src/AdvisoryAI/__Tests/StellaOps.AdvisoryAI.Tests/StellaOps.AdvisoryAI.Tests.csproj --no-build` passes.
