[AZ-305] c6 PostgresFilesystemStore: TileStore + TileMetadataStore impl
Adds the production PostgresFilesystemStore implementing both protocols in a single class. Filesystem-backed JPEG I/O (atomic sidecar write, read-only mmap) + Postgres-backed metadata (spatial bbox, LRU, voting, upload bookkeeping). Wires composition via `from_config` classmethod. Key behaviors: - AC-3 strict reading: INSERT runs first inside an open transaction; duplicate-key collisions raise `TileMetadataError` BEFORE any byte is written, leaving the original file + sidecar byte-identical. Atomic sidecar write happens inside the same transaction; commit closes it. Comp-delete remains as a safety net for the rare commit-after-write failure path. - AC-2 content-hash gate runs before any I/O. - Construction performs an orphan-file reconciliation scan and emits an INFO `c6.store.construct` log with steady-state stats. Adds `c6.write` and `c6.write_failed` FDR record kinds (schema v1.1.0, forward-compatible) and a thin operator CLI at `c6_tile_cache.tools dump` for inspection. Dependencies: adds `psycopg-pool>=3.2,<4.0` for the connection pool used on the F3 read-hot path. Tests: 25 new tests for c6_tile_cache cover AC-1..AC-15 plus MmapTilePixelHandle + helper round-trips. Full Tier-2 unit suite passes (1215 passed, 8 skipped, 1 pre-existing unrelated failure `test_ac8_read_host_tuple_on_jetson` — missing `pynvml` on macOS, Jetson-only).

"""AZ-305 — ``PostgresFilesystemStore`` acceptance + NFR tests.
|
||||
|
||||
All AC-1..AC-15 tests are ``@pytest.mark.docker`` (the module-level
|
||||
``pytestmark``) because they exercise a real Postgres + the on-disk JPEG
|
||||
layout. Two narrow non-docker tests live at the top of the file and
|
||||
exercise :class:`MmapTilePixelHandle` against a ``tmp_path`` file +
|
||||
the ``_quality_to_dict`` / ``_row_to_metadata`` helpers — these
|
||||
guarantee the mmap path stays read-only (Invariant I-4) and the DTO
|
||||
round-trip stays stable independent of the DB harness.
|
||||
|
||||
To run the docker tests locally::
|
||||
|
||||
docker compose -f docker-compose.test.yml up -d db
|
||||
GPS_DENIED_TIER=2 DB_URL=postgresql://gps_denied:dev@localhost:5432/gps_denied \\
|
||||
pytest tests/unit/c6_tile_cache/test_postgres_filesystem_store.py
|
||||
|
||||
The conftest auto-skips ``docker`` markers when ``GPS_DENIED_TIER != 2``.
