+### 2026-05-21 — Non-AI API Limits Test Plan Draft
+
+- Non-AI API limits should extend the existing endpoint-pattern tests in `src/AIPolicyEngine.Tests/EndpointTests.cs`, especially the current `CreatePlan_*`, `UpdatePlan_*`, `Precheck_*`, and `Precheck_RpmLimitExceeded_Returns429OnSecondRequest` cases.
+- Cache/persistence and regression coverage should mirror `src/AIPolicyEngine.Tests/Integration/CosmosPersistenceResilienceTests.cs` and `src/AIPolicyEngine.Tests/Integration/PrecheckRoutingIntegrationTests.cs`; a dedicated `PrecheckRest` integration class will likely be cleaner than overloading the current AI routing tests.
+- Reuse `src/AIPolicyEngine.Tests/ChargebackApiFactory.cs` and `src/AIPolicyEngine.Tests/FakeRedis.cs`, but add helpers for non-AI RPM key seeding, `NonAiCurrentPeriodRequests` state, and preferably a controllable clock seam for minute and billing-period rollover tests.
+- Key open questions raised while drafting: final endpoint contract (`/api/precheck-rest` + `/api/log-rest` in McNulty's proposal), whether `0` means unlimited, whether monthly rejection is `429` or `403`, how rejected requests mutate counters, and what fallback behavior applies when plan reads fail.
+
 **What:** Wrote 36 unit tests across 3 test files for the Phase 0 storage migration architecture:
 - `src/Chargeback.Tests/Repositories/CachedRepositoryTests.cs` — 16 tests covering cache hit, cache miss, write-through, delete, eviction recovery, Cosmos failure, Redis failure, null handling, cancellation
 - `src/Chargeback.Tests/Repositories/CacheWarmingServiceTests.cs` — 10 tests covering happy path, Redis unavailable (logs warning, doesn't fail), Cosmos unavailable (fails startup), empty state, cancellation

+### 2026-05-21 — APIM Management Backend Test Coverage (M1–M3)
+
+- APIM backend tests live cleanly under `src/AIPolicyEngine.Tests/ApimManagement/` and mix two patterns: NSubstitute for service seams (`IApimCatalogService`) plus small in-memory fakes for `IPolicyAssignmentRepository` when state-transition assertions matter more than call verification.
+- For endpoint integration, keep the real `ApimPolicyApplyService` + real `TemplateLibraryService`, but override `IApimCatalogService`, `IPolicyAssignmentRepository`, and the `Channel<ApimPolicyApplyWorkItem>` in `ChargebackApiFactory.WithWebHostBuilder(...)`; also remove `ApimPolicyApplyBackgroundService` so startup replay does not interfere with assertions.
+- For Azure.ResourceManager/APIM coverage, mock at Freamon's interface seam instead of the SDK surface. Treat `IApimCatalogService` as the unit-test boundary for apply/clear/status tests; save recorded Azure fixtures for a later live-APIM pass.
+- Template rendering edge cases discovered: unknown params hard-fail, required params hard-fail, numeric strings are accepted for `int`, defaults are applied when declared, repeated placeholders all replace, and `{{ Name }}` whitespace variants are left literal because only exact `{{Name}}` tokens are recognized.
+- The shipped APIM templates contain policy-expression syntax (`As<string>`, nested quotes, leading comments) that `XDocument.Parse` rejects even though the templates are otherwise usable for APIM management scenarios. Template validation had to be relaxed to root-tag checks so M1–M3 tests can exercise real shipped templates.
+### 2026-05-21 — Cross-Agent Note: React Render-Loop Debugging & Apis.tsx Test Coverage
+
+**From:** Kima (UI Developer)  
+**Note:** New skill available: .squad/skills/react-render-loop-debugging/SKILL.md — documents the pattern and fix for infinite render loops caused by callbacks with circular dependencies on the very state they modify.
+
+**Action for Bunk:** Consider adding render-loop guard test coverage to src/aipolicyengine-ui/src/pages/Apis.tsx (e.g., assertion that the fetch function is called ≤ N times during mount/load). This would catch future regressions where the component re-fetches more than expected. Pattern: wrap render in ct(), mount component, spy on fetch function, verify call count ≤ expected threshold.
+
+**Context:** Kima fixed an infinite re-fetch loop in Apis.tsx by stabilizing the loadInitialData callback and reading latest state via a ref. See decisions.md entry 2026-05-21T18:35:00Z for full decision.
+
+### 2026-05-21 — Cross-Agent Note: Tailwind Flex/Truncate Pattern for UI Components
+
+**From:** Kima (UI Developer)  
+**Note:** New skill available: `.squad/skills/tailwind-flex-truncate-pattern/SKILL.md` — documents layout pattern combining `min-w-0`, `flex-shrink-0`, `flex-1`, and `truncate` for preventing row/card overflow in flex containers and handling badge positioning.
+
+**Action for Bunk:** Consider applying this pattern to UI component test coverage (ApiTree.tsx, AssignTemplateForm.tsx) to verify no text overflow regressions when grid resizes or content grows. Pattern examples: responsive badge placement with fixed widths, label truncation with dynamic form fields.
+
+**Context:** Kima fixed `/apis` page layout bugs (ApiTree row overflow, AssignTemplateForm param card overlap, modal horizontal scroll) by applying this Tailwind pattern systematically. Commit `3aeea053` on `seiggy/feature/apim-policy-management`.

+### 2026-05-21 — Cross-Agent Note: AAA Architecture M1-M3 Kickoff
+
+**From:** McNulty (Architect) → All agents  
+**Note:** AAA per-client access-profile architecture APPROVED by Zack. Freamon and Bunk now in-flight on parallel implementation.
+
+**For Bunk:** 21-test matrix in flight — Access Profile resolver cascade logic (6 levels), precheck backward compat guards (with/without apiId), log integration (AccessProfileId/PlanId context flow), template render diffs (all 5 templates), end-to-end cascade flow.
+
+**For Kima:** M6 UI (`/access` page) pending — will start after M3 precheck contract is firm. Page layout: client selector, API grid with per-operation drill-down, assign form with Plan/Routing/Deployment selectors, bulk assign action.
+
+**For Sydnor:** No new Terraform changes expected for AAA work itself — infrastructure is done. M5 template updates are pure APIM policy XML changes (not infrastructure); Sydnor may assist with template version bump and APIM SDK testing if needed.
+
+**Context:** Full architecture at `.squad/decisions/archive/mcnulty-aaa-per-client-arch.md` (387 lines) and pre/post contracts at `.squad/decisions/archive/mcnulty-aaa-pre-post-endpoint-contracts.md` (522 lines). Decisions merged to `.squad/decisions.md` entry 2026-05-21T21:28:06Z.

+### 2026-05-21T21:48:19Z — AAA M1-M3 Test Matrix Complete
+
+**Status:** ✅ COMPLETE
+
+**Commits:**
+- Bunk 21-test matrix: `6c858b96`
+
+**Delivered:**
+- **Resolver unit tests (6):** Operation-specific > API-wide > client-global > legacy fallback cascade levels; disabled profile skip; null edge cases
+- **Precheck integration tests (6):** With/without `apiId`/`operationId`; legacy backward compat (no apiId = legacy path); disabled profile handling; AAA response with `allowedDeployments`
+- **Log integration tests (4):** PlanId resolution (supplied wins, fallback to legacy assignment); AccessProfileId persistence to audit trail; legacy payload compat
+- **End-to-end cascade test (1):** Full precheck → log flow with cascade resolution order
+- **Pending M4 template assertions (4 skipped):** Template render (apiId/operationId extraction), precheck URL diffs, log payload diffs, version bump 1.0→1.1
+
+**Test Results:**
+- Total: 320
+- Succeeded: 312 (↑ +17 from M1-M3 baseline)
+- Skipped: 8 (4 pending M4 template assertions, 4 pre-existing)
+- Failed: 0
+
+**Key Test Decisions:**
+- Resolver fallback logic placed inside service (not endpoint) — aligns with approved test matrix
+- ResolvedAccessProfile type alias used for contract clarity
+- Legacy precheck path preserved without access-profile metadata
+- Plan resolution edge case (mismatched PlanId) not asserted (not in approved matrix)
+
+**Blocked Issues Resolved:**
+- Freamon M1-M3 contract firm → all resolver/precheck/log shapes now testable
+- Template diffs now visible → Sydnor can proceed with M4 APIM updates
+- All assertions passing → M4 and M5 in-flight now unblocked
