+# Sprint 20260211_019 - AdvisoryAI Unchecked Feature Verification Batch 2
+
+## Topic & Scope
+- Continue FLOW-based verification for remaining unchecked `advisoryai` features after previous batch completion.
+- Enforce problems-first checks before selecting new queued advisory features.
+- Produce Tier 0/1/2 evidence and move terminally verified features to `docs/features/checked/advisoryai/`.
+- Working directory: `src/AdvisoryAI`.
+- Expected evidence: `docs/qa/feature-checks/runs/advisoryai/**`, `docs/qa/feature-checks/state/advisoryai.json`, feature-file moves.
+
+## Dependencies & Concurrency
+- Depends on `docs/qa/feature-checks/FLOW.md` and `src/AdvisoryAI/**`.
+- Cross-directory updates in `docs/features/**`, `docs/qa/feature-checks/**`, and `docs/implplan/**` are required for auditable verification.
+- Concurrent-agent constraint: if another module is already in `checking` and actively owned by other agents, do not take over contested files; record skip reason and continue available AdvisoryAI queue.
+
+## Documentation Prerequisites
+- `docs/qa/feature-checks/FLOW.md`
+- `src/AdvisoryAI/AGENTS.md`
+- `docs/modules/advisory-ai/architecture.md`
+
+## Delivery Tracker
+
+### QA-AIAI-VERIFY-004 - Verify `ai-codex-zastava-companion`
+Status: DONE
+Dependency: none
+Owners: QA / Test Automation
+Task description:
+- Verify Codex/Zastava companion implementation claims in AdvisoryAI source, contracts, web endpoints, and companion test suite.
+- Capture Tier 0 source evidence, Tier 1 build/test evidence, and Tier 2 behavioral endpoint/service evidence.
+- Move feature file from `docs/features/unchecked/advisoryai/` to `docs/features/checked/advisoryai/` on pass.
+
+Completion criteria:
+- [x] Tier 0 source verification completed.
+- [x] Tier 1 build and test verification completed.
+- [x] Tier 2 behavioral verification completed with fresh run evidence.
+- [x] State file updated and feature moved to checked.
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2026-02-11 | Sprint created; started `ai-codex-zastava-companion` verification with run-001. | QA |
+| 2026-02-11 | `ai-codex-zastava-companion` verification completed (`run-001`): companion service, contracts, endpoint behavior, and companion test suite passed; feature moved to `docs/features/checked/advisoryai/`. | QA |
+| 2026-02-11 | Re-verified `ai-codex-zastava-companion` with fresh `run-002` Tier 0/1/2 artifacts and updated checked-doc verification links. | QA |
+| 2026-02-11 | Re-verified `ai-action-policy-gate` with `run-002` after adding action workflow integration coverage for approval audit path and idempotent replay. | QA |
+
+## Decisions & Risks
+- Cross-module problem state detected: `attestor/ai-authority-classification-engine` is in `checking`.
+- Concurrency decision: treat cross-module ownership as obstacle and continue AdvisoryAI queue to avoid contested edits.
+- Risk: `dotnet test --filter` may emit `MTP0001` and execute full test assembly under Microsoft.Testing.Platform.
+- Mitigation: capture logs and record warning in run artifacts.
+- Decision: previous `NOT_FOUND` feature dossier was stale; current codebase includes `CodexZastavaCompanionService`, companion contracts, and `POST /v1/advisory-ai/companion/explain` endpoint with passing endpoint/service tests.
+- Decision: for targeted Tier 2 evidence, used xUnit runner class filters (`*.Tests.exe -class ...`) to avoid MTP filter ambiguity.
+- Decision: refreshed checked feature verification references to `run-002` where new evidence was captured.
+
+## Next Checkpoints
+- AdvisoryAI batch complete; proceed to the next module selected by FLOW problem-state ordering.
