Production code:
- POST /api/satellite/tiles/inventory (XOR body, 5000-cap,
most-recent-per-location_hash select, present/absent shaping).
- Kestrel HttpProtocols.Http1AndHttp2 on every listener (AC-5).
- Migration 015 creates tiles_leaflet_path covering index over
(location_hash, captured_at DESC, updated_at DESC, id DESC)
INCLUDE (file_path, source); drops superseded idx_tiles_location_hash.
- TileRepository.GetByTileCoordinatesAsync rewired to filter by
location_hash (Index Only Scan via tiles_leaflet_path).
- TileRepository.GetTilesByLocationHashesAsync added with Npgsql-
direct ANY($1::uuid[]) binding (Dapper IEnumerable expansion is
incompatible with the array form).
- Uuidv5.LocationHashForTile centralises the UUIDv5(TileNamespace,
"{z}/{x}/{y}") formula — single source of truth for the cross-repo
invariant (gps-denied-onboard parity).
Contracts:
- New: contracts/api/tile-inventory.md v1.0.0.
- Bumped: contracts/data-access/tile-storage.md to v2.0.0 (joint
ownership by AZ-503-foundation + AZ-505: schema + covering index +
GetByTileCoordinatesAsync rewrite).
Tests:
- TileInventoryTests covers AC-1, AC-2 (DB-level), AC-4, AC-6.
- Http2MultiplexingTests covers AC-5 (20 concurrent multiplexed GETs
over h2c via SocketsHttpHandler + AppContext Http2Unencrypted switch).
- LeafletPathIndexOnlyTests covers AC-3 (EXPLAIN (ANALYZE, BUFFERS)
asserts Index Only Scan over tiles_leaflet_path with heap_blocks=0).
Docs:
- architecture.md, system-flows.md, data_model.md, module-layout.md,
glossary.md, modules/api_program.md, modules/dataaccess_tile_repository.md,
components/02_data_access/description.md all updated to reference the
v2.0.0 tile-storage contract + new tile-inventory contract + AC-7.
Reports:
- batch_01_cycle6_report.md, batch_01_cycle6_review.md,
implementation_completeness_cycle6_report.md (PASS),
implementation_report_tile_inventory_cycle6.md.
Task spec moved todo/ -> done/.

Add per-source tile rows to support multi-provider imagery (Google
Maps + future UAV). Migration 013 (transactional) introduces
source/captured_at columns, backfills existing rows to
(source='google_maps', captured_at=created_at), and replaces the
4-column unique index with a 5-column index that includes source.
TileRepository:
- ColumnList includes source + captured_at
- GetByTileCoordinatesAsync returns most-recent row across sources
(ORDER BY captured_at DESC, updated_at DESC, id DESC)
- GetTilesByRegionAsync uses DISTINCT ON to pick the most-recent
tile per cell, restoring caller-facing row order
- Insert/Update upsert on the new 5-column conflict key
TileSource enum lives in Common.Enums. Snake_case wire format
(google_maps, uav) is enforced by a focused TileSourceTypeHandler
because the generic ToLowerInvariant pattern would emit
"googlemaps", violating contract v1.0.0.
TileService stamps Source=GoogleMaps + CapturedAt=UtcNow on every
new tile. Tile-storage contract is now frozen at v1.0.0.
AC coverage 7/7. New unit + integration tests cover all ACs;
existing 200 unit + 5 smoke tests preserved.

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.
