## Phase-by-Phase Summary (cumulative)

### Phase 1: Context Loading

The 3 batches share a coherent theme — **test infrastructure hardening** — with one piggybacked dependency hygiene task (AZ-496) and one convention-formalization task (AZ-495). All work targets test-side artifacts or documentation; production source code is untouched except for the version strings in `SatelliteProvider.Api.csproj`.

### Phase 2: Spec Compliance

Across the 6 tasks (AZ-495, AZ-496, AZ-491, AZ-493 — plus the deferred AZ-492 + AZ-494): every AC is either verified at code level or explicitly deferred to Step 16 with structural prerequisites met. Two spec-vs-reality findings recorded (AZ-496 Tests.csproj non-existent direct ref; AZ-493 DB-name-`_test` not actual). Both are documented inline with workarounds and recorded as cycle-3 Low findings.

### Phase 3: Code Quality (cumulative)

- No duplicate class names introduced. `JwtTokenFactory` lives in exactly one location (`SatelliteProvider.TestSupport`); the cycle-2 duplicate at `SatelliteProvider.Tests/TestUtilities/JwtTokenFactory.cs` was deleted by batch 02.
- The pure-vs-side-effect separation pattern is consistent across both new TestSupport surfaces:
  - `JwtTokenFactory` (pure: stateless, no I/O) in TestSupport — `JwtTestHelpers` (side-effectful: env reads, `HttpClient` mutation) in IntegrationTests.
  - `IntegrationTestResetGuard` (pure: stateless, no I/O) in TestSupport — `IntegrationTestDatabaseReset` (side-effectful: Npgsql connection + transaction) in IntegrationTests.
- All new classes follow SRP. Errors are surfaced explicitly (no silent suppression). No verbose debug logging added.

### Phase 4: Security Quick-Scan (cumulative)

- AZ-496 *reduces* attack surface by closing CVE-2026-26130 (not reachable in this app, but the runtime patch is the recommended hardening).
- AZ-491 reduces *test-credential drift* risk — the same security-relevance bug in two places will no longer require parallel fixes. Code-review SKILL Phase 6 now carries an active rule that prevents this from recurring.
- AZ-493 adds a defense layer against accidental truncate against production / staging databases. The two-guard model (env sentinel + Host allowlist) is conservative-by-default and unit-tested with representative production-shape hostnames.
- No new secrets in repo. No new attack surface in production code (no production code changed except a patch-level version bump).

### Phase 5: Performance Scan (cumulative)

No performance-affecting changes in production code paths. AZ-493 adds one Npgsql round-trip at integration-test startup; AZ-493 NFR budget (< 1 s on O(10K) rows) is satisfied by Postgres TRUNCATE behavior. No hot-path or memory-allocation regressions.

### Phase 6: Cross-Task Consistency (cumulative)

- **TestSupport project consistency**: AZ-491 introduced the `SatelliteProvider.TestSupport` project for shared test utilities; AZ-493 extended it with `IntegrationTestResetGuard`. The project's role is now firmly established as "pure utility surfaces, no production-code dependency, consumed by both unit + integration test projects". Both batches followed the same boundary discipline.
- **module-layout.md consistency**: Updated by batch 1 (Documentation Layout convention + WebApi PackageReferences), batch 2 (TestSupport entry added), batch 3 (TestSupport entry extended with the guard). Three updates, three different sections, zero contradictions or conflicting prose.
- **tests_integration.md consistency**: Updated by batch 2 (JwtIntegrationTests line — JWT helper consolidation) and batch 3 (Reliability section added + UavUploadTests defense-in-depth note). Updates are non-overlapping; the cumulative narrative is coherent.
- **Code-review SKILL.md consistency**: Phase 6 gained a duplicate-helper detection rule in batch 2. This same rule, applied to batch 2 itself, validates the AZ-491 work (which was the consolidation triggering the rule). Self-consistent.

### Phase 7: Architecture Compliance (cumulative)

- **Layer direction**: No production projects gained or lost cross-component dependencies. TestSupport sits *outside* the production layering table — referenced only by `Tests` + `IntegrationTests` test projects. Production-code Layer-3 / Layer-4 invariants are unchanged.
- **Public API respect**: No internal symbol exposures across components. The cycle-3 work intentionally split pure logic (visible to unit tests via TestSupport) from side-effectful code (kept in the consumer test project that already had the dependency).
- **Cyclic dependencies**: None introduced. Dependency graph for the test infrastructure:
  - `SatelliteProvider.TestSupport` → (`Microsoft.IdentityModel.Tokens` 7.0.3, `System.IdentityModel.Tokens.Jwt` 7.0.3) — no ProjectReferences.
  - `SatelliteProvider.Tests` → (TestSupport, Api, Common, DataAccess, Services.*) — no cycle.
  - `SatelliteProvider.IntegrationTests` → (TestSupport) — no cycle.
- **Duplicate symbols across components**: Zero. Verified via `grep -nE 'public (sealed |static )?class (JwtTokenFactory|IntegrationTestResetGuard|IntegrationTestDatabaseReset|JwtTestHelpers)'` — each name appears exactly once in canonical location, plus test classes appear once in `SatelliteProvider.Tests/`.
- **Cross-cutting concerns not locally re-implemented**: All test-side cross-cutting concerns introduced by cycle 3 (JWT minting, integration-test reset guard) live in TestSupport — exactly where they should. Production-side cross-cutting concerns (logging, configuration loading) were not touched.

## Baseline Delta (cumulative)

| Class | Count | Notes |
|-------|-------|-------|
| Carried over | 0 | Architecture baseline (cycle 1) had 0 entries; no cycle-2 entries to carry |
| Resolved | 2 (informal) | Cycle-2 retro Pattern 1 (duplicate JWT mint helpers) + Pattern 5 (integration-test state leakage) — both structurally closed. Not Architecture-class entries, so they do not appear in the cycle-1 baseline; tracked here for the cycle-3 retrospective |
| Newly introduced | 0 | — |

## Recurring patterns to surface for cycle-3 retrospective

1. **Task-spec accuracy vs. codebase reality**: Two of three Spec-Gap findings in this cumulative review are about specs encoding assumptions that weren't verified against the codebase before authoring (AZ-496 Tests.csproj reference; AZ-493 DB-name `_test` convention). The cycle-1 + cycle-2 F1 (doc-path drift) is the same pattern. AZ-495 closed the doc-path drift specifically; the broader pattern ("verify the assertion in the codebase before encoding it as AC text") is a candidate for a new-task / decompose checklist row. Recommend explicit retrospective discussion.
2. **The pure-vs-side-effect separation pattern**: AZ-491 and AZ-493 both followed it (pure helper in TestSupport; side-effectful consumer in IntegrationTests). Worth codifying in the decompose-skill task template or the code-review SKILL.md so this becomes the default pattern for future test-infrastructure work.
3. **Defense-in-depth as an explicit deliverable**: AZ-493 chose to retain the cycle-2 wallclock seed alongside the new reset hook. This decision was documented in code + batch report + module docs. Pattern is healthy and worth normalizing — when a workaround predates the proper fix, retaining the workaround as a fallback with an inline comment back-reference is cheaper than removing it and re-discovering its purpose later.

## Verdict Logic

- 0 Critical, 0 High, 0 Medium, 4 Low (all surfaced as per-batch findings; cumulative scan found no new categories) → **PASS_WITH_WARNINGS**

## Recommendation to /implement

Cumulative review passes. **Continue to Step 14 loop (next batch)** — AZ-492 (perf harness PT-07 + PT-08 + JWT-attach, 3 SP) is next per the recommended execution order.
