## Changes

### AZ-376 — delete unused `FindExistingTileAsync`
- `SatelliteProvider.DataAccess/Repositories/ITileRepository.cs`: removed declaration on line 9 (no callers per grep before deletion).
- `SatelliteProvider.DataAccess/Repositories/TileRepository.cs`: removed implementation (lines 51-76).
- Removed dependency on the obsolete `version` argument that C06/AZ-357 was retiring.

### AZ-378 — repo `_logger` fields cleanup (recommended split)
- `TileRepository.cs`:
  - Added `private const int SlowQueryThresholdMs = 500` (named const, easy to tune later).
  - `GetTilesByRegionAsync` wraps the Dapper call in `Stopwatch.StartNew()` / `Stop()` and emits `_logger.LogWarning(...)` if elapsed > threshold. Includes structured fields (`ElapsedMs`, `ThresholdMs`, `Latitude`, `Longitude`, `SizeMeters`, `ZoomLevel`).
  - Added `using System.Diagnostics`.
- `RegionRepository.cs`: removed `_logger` field, removed `ILogger<RegionRepository>` constructor parameter, removed `using Microsoft.Extensions.Logging`.
- `RouteRepository.cs`: same pattern.
- `SatelliteProvider.Api/Program.cs:33-34`: DI registrations for `IRegionRepository` and `IRouteRepository` now construct without the `ILogger<TRepo>` arg.

### AZ-379 — extract repo `ColumnList` constants
- `TileRepository.cs`: `private const string ColumnList = @"id, tile_zoom as TileZoom, ..."` interpolated into `GetByIdAsync`, `GetByTileCoordinatesAsync`, `GetTilesByRegionAsync` via `const string sql = $@"SELECT {ColumnList} FROM ..."`. INSERT/UPDATE/DELETE statements unchanged (out of scope per spec).
- `RegionRepository.cs`: same pattern; constant covers `GetByIdAsync` + `GetByStatusAsync`.
- `RouteRepository.cs`: same pattern; constant covers the two `routes`-table SELECTs (`GetByIdAsync` + `GetRoutesWithPendingMapsAsync`). `GetRoutePointsAsync` (single `route_points` SELECT) left inline — a second const would not reduce duplication.
- C# 10+ const-interpolated strings supported by net8.0 target; compile-time guarantee that the column list is identical across SELECTs.

### AZ-380 — delete dead alias `CalculatePolygonDiagonalDistance`
- `SatelliteProvider.Common/Utils/GeoUtils.cs:129-132`: removed (no callers per grep).

### Tests added

`SatelliteProvider.Tests/RepositoryRefactorTests.cs` (8 tests):
- `TileRepository_DoesNotExposeFindExistingTileAsync_AZ376_AC1` (reflection)
- `TileRepository_KeepsAndUsesLogger_AZ378_AC1` (file content)
- `RegionRepository_HasNoUnusedLoggerParameter_AZ378_AC2` (reflection)
- `RouteRepository_HasNoUnusedLoggerParameter_AZ378_AC2` (reflection)
- `TileRepository_DefinesColumnListConstantOnce_AZ379_AC1` (file content)
- `RegionRepository_DefinesColumnListConstantOnce_AZ379_AC1`
- `RouteRepository_DefinesColumnListConstantOnce_AZ379_AC1`
- `RepositoryColumnLists_ContainExpectedColumns_AZ379_AC2` (per-repo column-token assertions)

`SatelliteProvider.Tests/GeoUtilsRefactorTests.cs` (1 test):
- `GeoUtils_DoesNotExposeCalculatePolygonDiagonalDistance_AZ380_AC1` (reflection)

Same file-content / reflection assertion pattern established by `ToolingConfigurationTests` (AZ-372 b22) and `AcceptanceCriteriaRT2Tests` (AZ-370 b19).

## AC Test Coverage

| AC | Covered by |
|----|------------|
| AZ-376 AC-1 (method gone) | `TileRepository_DoesNotExposeFindExistingTileAsync_AZ376_AC1` |
| AZ-376 AC-2 (build) | Successful Docker `dotnet test` Release build |
| AZ-376 AC-3 (tests green) | 190/190 unit run |
| AZ-378 AC-1 (kept logger used) | `TileRepository_KeepsAndUsesLogger_AZ378_AC1` |
| AZ-378 AC-2 (unused loggers removed) | `*_HasNoUnusedLoggerParameter_AZ378_AC2` (×2) |
| AZ-378 AC-3 (tests green) | 190/190 unit run |
| AZ-379 AC-1 (one ColumnList per repo) | `*_DefinesColumnListConstantOnce_AZ379_AC1` (×3) |
| AZ-379 AC-2 (SQL byte-identical) | `RepositoryColumnLists_ContainExpectedColumns_AZ379_AC2` (column tokens) + structural guarantee from compile-time interpolation; smoke run handed off to test-run skill |
| AZ-379 AC-3 (tests green) | 190/190 unit run |
| AZ-380 AC-1 (method gone) | `GeoUtils_DoesNotExposeCalculatePolygonDiagonalDistance_AZ380_AC1` |
| AZ-380 AC-2 (build) | Successful Docker build |
| AZ-380 AC-3 (tests green) | 190/190 unit run |

Stale-count note carried over from b22: each task spec phrases AC-3 as "37 unit + 5 smoke". Pre-`/document` figure; current count is 190 unit. Spirit ("all tests green") satisfied.

## Test Run

| Suite | Result | Count |
|-------|--------|-------|
| Unit (`SatelliteProvider.Tests`) | All passed | 190 (was 181; +9 new tests across 2 new files) |
| `dotnet format whitespace --verify-no-changes` | Clean | — |
| Smoke integration (Docker) | Handed off to test-run skill | — |

## Code Review Verdict: PASS_WITH_WARNINGS

Three Low findings (`_docs/03_implementation/reviews/batch_23_review.md`):
- F1 (Low / Maintainability): `route_points` column list left inline (single use). Spec is explicit ("one ColumnList per repository"). No action.
- F2 (Low / Spec-Gap): Earth-related literals still in `GetTilesByRegionAsync` — explicitly the target of AZ-377 (batch 24).
- F3 (Low / Spec-Gap): Stale "37 unit + 5 smoke" count in task ACs — same as b22 F1, defer to refactor Phase 7 doc sweep.

## Auto-Fix Attempts: 0
## Stuck Agents: None

## Cumulative review counter

This is batch 2 since the last cumulative review (`cumulative_review_batches_19-21_cycle1_report.md`). Counter at 2/3; **next cumulative review fires after batch 24** (covers batches 22-24).

## Next Batch

Phase 4 continues with the remaining 2 tasks in `todo/` after this batch:

- `AZ-375` — C22 O(N) existing-tile lookup HashSet (2 SP, dep AZ-371 ✓)
- `AZ-377` — C24 consolidate Earth-geometry constants + 111000 + TileSizePixels (2 SP, dep AZ-371 ✓)

Batch 24 candidate: both tasks together (~4 SP, both touch TileDownloader / Common / DataAccess). They form the last refactor batch; the K=3 cumulative review fires immediately after. Then Phase 4 of refactor wraps up and we move to Phase 5 (Test Sync), Phase 6 (Verification), Phase 7 (Documentation), then FINAL_report.md and Step 9 (New Task).
