- Stop writing "downloaded_YYYY-MM-DD" into tiles.maps_version: new rows
bind @MapsVersion to NULL via TileService.BuildTileEntity.
- Retain the tiles.maps_version column (coderule.mdc forbids unprompted
column drops); pre-existing rows keep their values for forensics.
- Remove MapsVersion property from DownloadTileResponse (API wire shape)
and TileMetadata (internal DTO); OpenAPI schema regenerates from the
DTO via Swashbuckle.
- Add 3 AC tests in TileServiceTests covering the captured-entity write
(AC-1) and the DTO/wire-shape removal (AC-2).
- Update integration-test local DTO + console output; refresh docs in
common_dtos.md, services_tile_service.md, data_model.md.
- Archive AZ-373 task file: todo/ -> done/.
174 unit + 5 smoke pass.

AZ-357 — eliminate year-based tile cache expiry (LF-1):
- Migration 012: drop 5-col unique index, dedupe by (lat,lon,zoom,
size) keeping max(updated_at), add new 4-col unique index, make
version column nullable + drop default. Column itself preserved
per coderule (column drops require explicit confirmation; tracked
in AZ-373 / C20).
- TileEntity.Version, TileMetadata.Version, DownloadTileResponse.
Version: int -> int? (HTTP shape preserved; field still in JSON).
- TileService.DownloadAndStoreTilesAsync: drop currentVersion year
computation and the .Where(t => t.Version == currentVersion)
cache filter. BuildTileEntity: drop year arg; write Version=null.
- TileRepository: ON CONFLICT now 4-col; lookup queries
ORDER BY updated_at DESC instead of version DESC.
- Tests: replace inverted BT02b with positive AZ357_AC1
(prior-year cached tile is reused). Add BuildTileEntity_
DoesNotPopulateVersion_AZ357 to enforce the no-write contract.
- 69 unit + 5 smoke + 3 stub-contract integration tests pass.
Cumulative code review (batches 7-9, 7 tasks): VERDICT=PASS.
Report at _docs/03_implementation/reviews/batch_09_review.md.
Zero Critical/High/Medium/Low findings. Architecture baseline
remains clean.
