[AZ-495] [AZ-496] Cycle 3 batch 1: doc convention + AspNetCore 8.0.25

AZ-495 (1 SP): formalize the modules-only documentation convention for
the WebApi component. _docs/02_document/module-layout.md now carries an
explicit Documentation Layout section anchoring WebApi docs at
modules/api_program.md; the components/06_web_api/ folder is
intentionally absent. .cursor/skills/new-task/SKILL.md Step 4 directs
future agents at the correct path. Cycle-1 + cycle-2 F1 findings in the
two batch-review files are marked RESOLVED with back-reference to
AZ-495. Cycle-2 retrospective decision-item list F1 updated.

AZ-496 (2 SP): bump Microsoft.AspNetCore.OpenApi and JwtBearer in
SatelliteProvider.Api.csproj from 8.0.21 to 8.0.25, closing CVE-
2026-26130 (SignalR DoS - not reachable in this app, but the runtime
patch is the recommended hardening per cycle-1 D1 + cycle-2 D3).
SatelliteProvider.Tests.csproj has no direct JwtBearer reference - it
consumes JwtBearer transitively via ProjectReference to Api, so no
edit needed there. Dockerfiles use floating mcr.microsoft.com/
dotnet/aspnet:8.0 / sdk:8.0 / runtime:8.0 tags which auto-resolve to
>= 8.0.25 on rebuild. Security artifacts (dependency_scan.md,
security_report.md) and current-state docs (module-layout.md,
architecture.md, modules/api_program.md, modules/tests_unit.md)
updated to reflect 8.0.25.

Batch report + code review report (verdict PASS_WITH_WARNINGS with 2
Low findings, neither blocking) written under _docs/03_implementation.

Test suite gate deferred to Step 16 (Final Test Run) per implement
skill convention. Patch-level bump within .NET 8 LTS; regression risk
very low.

+
+## What was implemented
+
+### AZ-495 — Doc-folder convention for WebApi
+
+Chose **Option B** (formalize modules-only convention). Rationale: WebApi is the Layer-4 orchestrator, not a Layer-3 service component; its documentation is already richly captured in `modules/api_program.md`; creating a duplicate `components/06_web_api/description.md` would establish two sources of truth.
+
+- `_docs/02_document/module-layout.md` § Documentation Layout added — explicit canonical convention with rationale. Anchors all future WebApi documentation at `modules/api_program.md`; the absence of a `components/06_web_api/` folder is now a documented invariant.
+- `.cursor/skills/new-task/SKILL.md` Step 4 (Codebase Analysis) updated to direct future agents at the correct path when a task touches WebApi.
+- `_docs/03_implementation/reviews/batch_01_cycle2_review.md` § F1 and `batch_02_cycle2_review.md` § F1 marked **RESOLVED in cycle 3 (AZ-495)** with back-reference.
+- `_docs/06_metrics/retro_2026-05-11_cycle2.md` § Decision Items Carried Over updated to mark F1 resolved.
+
+### AZ-496 — Bump AspNetCore.OpenApi + JwtBearer to 8.0.25
+
+- `SatelliteProvider.Api/SatelliteProvider.Api.csproj`: both `Microsoft.AspNetCore.OpenApi` AND `Microsoft.AspNetCore.Authentication.JwtBearer` bumped from `Version="8.0.21"` to `Version="8.0.25"`.
+- **Note vs task spec**: the spec called for an additional bump in `SatelliteProvider.Tests/SatelliteProvider.Tests.csproj`. Verification showed `Tests.csproj` has no direct `JwtBearer` PackageReference — its JwtBearer usage flows transitively through `ProjectReference` to `SatelliteProvider.Api`, so the Tests project automatically picks up `8.0.25` once Api.csproj is bumped. The spec was inaccurate on this point; no Tests.csproj edit was made. The cycle-2 dependency-scan delta entry for D3 has been updated to reflect this.
+- Dockerfiles (`SatelliteProvider.Api/Dockerfile`, `SatelliteProvider.IntegrationTests/Dockerfile`): both use the floating `mcr.microsoft.com/dotnet/aspnet:8.0` / `:sdk:8.0` / `:runtime:8.0` tags which auto-resolve to ≥ 8.0.25 on rebuild. No Dockerfile edit needed; AC-2 satisfied automatically.
+- `_docs/05_security/dependency_scan.md`: D1 and D3 entries marked **RESOLVED (cycle 3, AZ-496)** with detailed disposition update.
+- `_docs/05_security/security_report.md`: D1 row in cycle-1 findings table marked RESOLVED; D3 row in cycle-2 findings table marked RESOLVED; cycle-2 "Recommended cycle-3 hardening" entry marked **DONE**.
+- `_docs/02_document/module-layout.md` WebApi section, `_docs/02_document/architecture.md` § Authentication & Authorization, `_docs/02_document/modules/api_program.md` Dependencies, `_docs/02_document/modules/tests_unit.md` NuGet: all version-pinning prose updated from `8.0.21` → `8.0.25` with back-reference to AZ-496.
+
+## Open follow-ups (non-blocking)
+
+- **Test suite gate**: AZ-496 AC-3 requires `./scripts/run-tests.sh --full` to pass. Deferred to Step 16 (Final Test Run) per the implement skill's convention. If the patch-level bump regressed anything, this gate catches it; for an 8.0.21 → 8.0.25 patch within the same .NET 8 LTS line, regressions are very unlikely.
+- **D2 (Microsoft.NET.Test.Sdk 17.8.0 → 17.9.0+)**: NOT addressed in this batch. Mentioned in AZ-496 spec § Excluded as a separate decision. The cycle-3 dependency-bump backlog now contains only D2 (test-only Low). No immediate action; defer to a future cycle's hardening sweep.
+- **Runtime base image pinning policy**: this batch confirmed the floating `8.0` tag works for picking up runtime patches automatically. The trade-off (auto-update vs. reproducible builds) was not formally documented as a project decision; if the team prefers explicit version pinning, that is a future cleanup task. Not in scope of AZ-496.
+
+## Next Batch: AZ-491 (Consolidate JWT test-mint helpers)
+
+AZ-491 is a 3 SP refactor of test infrastructure. It moves `JwtTokenFactory` to a shared location consumed by both `SatelliteProvider.Tests` and `SatelliteProvider.IntegrationTests`, deletes the duplicate `JwtTestHelpers.MintValidToken` / `MintExpiredToken` / `TamperSignature` from the integration project, and adds a code-review checklist row to flag future duplicates. The implementer must pick Option A (new `SatelliteProvider.TestSupport` library) or Option B (Integration tests reference Unit tests directly) at the start of the batch.
