[AZ-286] [AZ-287] [AZ-288] Service-level unit tests (mocked deps)

Batch 2: 27 new tests, 31/31 total passing. AZ-286 TileService (9 tests): - BT-01 download stores tiles via repository - BT-02 cache reuse passes existing tiles to downloader - BT-02b stale-version cached tiles are NOT treated as still-valid - BT-N02 GoogleMapsDownloaderV2 rejects zoom levels not in {15..19} - GetTileAsync known/unknown id AZ-287 RegionService (6 tests): - AC-1 RequestRegionAsync inserts entity and queues request - AC-2/AC-3 ProcessRegionAsync transitions queued→processing→completed and writes CSV + summary files - AC-4 stitch path is set when stitchTiles=true - ProcessRegionAsync handles RateLimitException by writing failed summary with the error message preserved - GetRegionStatusAsync mapping - Missing region id is logged and short-circuits without DB writes AZ-288 RouteService (12 tests): - AC-1 every consecutive pair is ≤200m apart on 2-point route - AC-2 first/last user points keep their roles; middles are interpolated - BT-10 10pt route → 1 start, 1 end, 8 action, plus intermediates - BT-12 20pt route → 1 start, 1 end, 18 action - AC-3 TotalDistanceMeters == Σ Haversine(point[i-1], point[i]) - BT-N03 < 2 points throws ArgumentException - regionSize <100 / >10000 throws ArgumentException - BT-N04 (0,0) corner throws - BT-N05 inverted NW.lat <= SE.lat throws - BT-11 valid geofence creates region requests + links them with isGeofence=true - BT-07 GetRouteAsync returns route + points - GetRouteAsync unknown id returns null Code review: PASS_WITH_WARNINGS — 3 Low Spec-Gap findings: 1. BT-N01 (invalid coords) deferred to AZ-289 integration tests (TileService doesn't validate coordinates — API-layer concern) 2. Point-type label drift between blackbox-tests.md ("original") and code ("start"/"action"/"end") 3. Region status drift: spec "pending" vs code "queued" — initial state on insert Verification: docker dotnet test — 31/31 pass in 0.83s. Co-authored-by: Cursor <cursoragent@cursor.com>

+- BT-N01 deferred to AZ-289 integration tests (TileService does not validate coordinates — API-layer concern).

+## Code Review Verdict: PASS_WITH_WARNINGS
+
+3 Low Spec-Gap findings (deferred BT-N01, point-type naming drift, status naming drift).

+# Code Review Report
+
+**Batch**: 2 — AZ-286 + AZ-287 + AZ-288 (TileService / RegionService / RouteService unit tests)
+**Date**: 2026-05-10
+**Verdict**: PASS_WITH_WARNINGS
+
+## Findings
+
+| # | Severity | Category | File:Line | Title |
+|---|----------|----------|-----------|-------|
+| 1 | Low | Spec-Gap | (deferred) | BT-N01 (invalid coords) not unit-tested — TileService does not validate lat/lon |
+| 2 | Low | Spec-Gap | (docs) | Point-type label drift between blackbox-tests.md ("original"/"intermediate") and code ("start"/"action"/"end"/"intermediate") |
+| 3 | Low | Spec-Gap | (docs) | Region status drift: blackbox-tests.md "pending → processing → completed" vs code "queued → processing → completed" |
+
+### Finding Details
+
+**F1: BT-N01 not service-unit-tested** (Low / Spec-Gap)
+- Location: out-of-scope for `TileService`
+- Description: AZ-286 lists BT-N01 (invalid lat/lon) but neither `TileService.DownloadAndStoreTilesAsync` nor `GoogleMapsDownloaderV2.DownloadSingleTileAsync` validates coordinate ranges. Validation lives at the API endpoint layer (`Program.cs`).
+- Suggestion: Cover BT-N01 in AZ-289 (integration tests) which exercises the HTTP API. Optionally add API-layer validation in a future testability/refactor step.
+- Tasks: AZ-286, AZ-289
+
+**F2: Point-type label drift** (Low / Spec-Gap)
+- Location: `_docs/02_document/tests/blackbox-tests.md` BT-06 / BT-10 / BT-12 vs `SatelliteProvider.Services/RouteService.cs:66`
+- Description: Test spec says first/last point type is `original`. Code emits `start` / `action` / `end` for user-supplied points and `intermediate` for interpolated. The spec's "original" appears to be a generic term for "user-supplied", which does not match any actual code value. RouteService unit tests assert the actual code values to keep tests honest.
+- Suggestion: Update `blackbox-tests.md` BT-06/BT-10/BT-12/BT-N* phrasing OR introduce an "original" alias in code. Either option is harmless but should be tracked. The traceability matrix should be updated to reflect the chosen wording.
+- Task: AZ-288 (and downstream test-spec sync in Step 12)
+
+**F3: Region status string drift** (Low / Spec-Gap)
+- Location: `_docs/02_document/tests/blackbox-tests.md` BT-03/BT-04 vs `SatelliteProvider.Services/RegionService.cs:48` (initial state = `"queued"`)
+- Description: Spec uses "pending → processing → completed". Code uses "queued → processing → completed". Tests assert the code's actual transitions.
+- Suggestion: Update test-spec to match code, or add a `"pending"` alias in code. Same trade-off as F2. Track in test-spec sync (Step 12).
+- Task: AZ-287
+
+## Phase Summary
+
+- **Phase 1 (Context)**: AZ-286/287/288 specs loaded; ACs identified.
+- **Phase 2 (Spec compliance)**:
+  - AZ-286 AC-1: 3/4 (BT-01 ✓, BT-02 ✓ + BT-02b stale-version, BT-N02 ✓; BT-N01 deferred → F1).
+  - AZ-286 AC-2: ✓ (`ISatelliteDownloader` is mocked everywhere; no real Google Maps).
+  - AZ-286 AC-3: ✓ (happy path + cache reuse + zoom validation negative).
+  - AZ-287 AC-1: ✓ (`RequestRegionAsync_InsertsEntityAndQueues_BT03_AC1`).
+  - AZ-287 AC-2: ✓ (`ProcessRegionAsync_HappyPath_TransitionsToCompletedAndWritesArtifacts_BT03_AC2_AC3` — verifies "processing → completed"; initial "queued" is set in `RequestRegionAsync`).
+  - AZ-287 AC-3: ✓ (CSV + summary files asserted on disk).
+  - AZ-287 AC-4: ✓ (`ProcessRegionAsync_StitchEnabled_SetsStitchedImagePath_BT05_AC4`).
+  - AZ-288 AC-1: ✓ (≤200m spacing iterated and verified).
+  - AZ-288 AC-2: ✓ (start/end/action/intermediate counts verified — see F2).
+  - AZ-288 AC-3: ✓ (`ComputesTotalDistanceViaHaversine_AC3` cross-checks `TotalDistanceMeters` against summed Haversine distances).
+  - AZ-288 AC-4: ✓ (BT-N03 < 2 points, region-size validation, BT-N04, BT-N05).
+- **Phase 3 (Quality)**: tests follow Arrange/Act/Assert; helpers (`BuildService`, `BuildRequest`, `MakeDownloaded`) keep arrange sections small; no duplication.
+- **Phase 4 (Security)**: no secrets, no injection vectors. The mock API key `"test-key"` in `GoogleMapsDownloaderZoomValidationTests` never escapes the test (no HTTP performed).
+- **Phase 5 (Performance)**: tests run in <1s total — no anti-patterns.
+- **Phase 6 (Cross-task)**: shared fixtures (`TestCoordinates`) used uniformly. Mock setups consistent across test files.
+- **Phase 7 (Architecture)**: tests sit in `SatelliteProvider.Tests/` and consume only Public API of Common, DataAccess, Services per `module-layout.md`. No layering violation. No new cycles. No duplicate symbols.
+
+## Test Run

+Container: `mcr.microsoft.com/dotnet/sdk:8.0`
