Verifies that _remote_attach table is actually found via table_catalog
and contains expected extension data (not just resilience).

Add _reattach_remote_extensions() helper that reads _remote_attach
tables from attached extract.duckdb files and LOADs the corresponding
DuckDB extensions, so BigQuery and other remote views resolve correctly
in read-only analytics connections.
Add SCHEMA_VERSION = 4, _V3_TO_V4_MIGRATIONS list, and if current < 4 block
in _ensure_schema(). Both new tables are also added to _SYSTEM_SCHEMA for
fresh installs. Tests cover fresh install, all columns, and v3→v4 migration path.
Prevents environment variable leaking between tests. All DATA_DIR,
JWT_SECRET_KEY, and SCRIPT_TIMEOUT assignments in fixtures now use
monkeypatch.setenv() which auto-reverts after each test. Removes
manual os.environ.pop() cleanup lines.
- Add close_system_db() function in src/db.py to cleanly close shared DB connection
- Add lifespan context manager in app/main.py to trigger shutdown on app exit
- Integrate lifespan into FastAPI app initialization
- All API tests pass (77/77)
Adds _SAFE_IDENTIFIER regex guard before ATTACHing extract.duckdb files in the
read-only analytics connection, matching the same fix already applied in the
orchestrator. Adds test coverage for malicious directory names.
Schema v3: add is_public column to table_registry (default true).
src/rbac.py: can_access_table() checks admin bypass, public flag,
explicit permissions, wildcard bucket permissions.
API enforcement:
- manifest: filters tables by user access
- download: 403 if no access
- catalog: filters table list
- query: validates referenced tables against allowed list
New admin permissions API (/api/admin/permissions) for grant/revoke.
28 access control tests + 733 total tests passing.
