+
+## Task Results
+
+| Task | Status | Files Modified | Tests | AC Coverage | Issues |
+|------|--------|---------------|-------|-------------|--------|
+| AZ-1132 | Done | 5 files | Validator unit: 144/144 PASS (host) | 5/5 ACs covered | Docker `protoc` segfault blocks `./scripts/run-tests.sh` on this host — Step 11 gate |
+
+## AC Test Coverage
+
+| AC | Verification |
+|----|--------------|
+| AC-1 | `SatelliteProvider.Api.csproj` pins FluentValidation + DI extensions at 12.1.1 |
+| AC-2 | `dotnet test --filter FullyQualifiedName~Validators` → 144 passed |
+| AC-3 | Integration validation suites deferred to Step 11 (`run-tests.sh` full) |
+| AC-4 | `dotnet list package --vulnerable` — Api has no vulnerable packages |
+| AC-5 | `dependency_scan_cycle15.md` + `security_report_cycle15.md` mark D-AZ795-1 Resolved |
+
+## Code Review Verdict: PASS
+
+Patch-level dependency bump only; no production logic, contract, or validator rule changes.

+## Auto-Fix Attempts: 0

+# Implementation Report — FluentValidation bump (Cycle 15)
+
+**Cycle**: 15
+**Tasks**: AZ-1132 (1 SP)
+**Feature slug**: fluentvalidation_bump
+
+## Summary
+
+Coordinated patch bump of `FluentValidation` and `FluentValidation.DependencyInjectionExtensions` from 12.0.0 to 12.1.1 in `SatelliteProvider.Api`. Closes D-AZ795-1.
+
+## Changes
+
+| Area | Change |
+|------|--------|
+| `SatelliteProvider.Api.csproj` | FluentValidation packages 12.0.0 → 12.1.1 |
+| Module docs | Version pins updated in `api_program.md`, `tests_unit.md` |
+| Security | `dependency_scan_cycle15.md`, `security_report_cycle15.md` — D-AZ795-1 Resolved |
+
+## Test Evidence
+
+- Validator unit tests (host): **144 passed** (`FullyQualifiedName~Validators`)
+- Full `./scripts/run-tests.sh`: **not run green** — Docker SDK container `protoc` exit 139 on `linux_arm64` (environment; unrelated to package bump). Step 11 is the canonical full-suite gate.
+
+## Verdict
+
+**Implementation complete** pending Step 11 full-suite confirmation.
