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INCLUDE (file_path, source); drops superseded idx_tiles_location_hash.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/.
