- Add app/db/ abstraction layer: Backend enum, DbConn wrapper,
dialect helper (q() for ? vs %s paramstyle), get_conn(), tenant_id()
- Auto-detect backend from DATABASE_URL; SQLite remains default when
unset — no config change for local deployments
- Add tenant_id column to all three logical DBs (main, context, incidents);
idempotent ALTER TABLE migration runs before schema scripts on existing DBs
- All INSERTs inject tenant_id; SELECTs use (tenant_id = ? OR tenant_id = '')
for backward compat with pre-namespacing rows
- Add docker-compose.yml with named volume turnstone_pgdata (survives rebuilds)
and optional external Postgres support via DATABASE_URL override
- Add scripts/migrate_sqlite_to_postgres.py — one-shot idempotent migration
for existing SQLite data; ON CONFLICT DO NOTHING for safe re-runs
- Fix SSH glean path in pipeline.py to use ensure_schema + get_conn
(was still using raw sqlite3.connect + old _SCHEMA without tenant_id)
- Fix FTS5 JOIN ambiguity: qualify repeat_count as f.repeat_count in search
- Update all tests to use ensure_*_schema fixtures; add row_factory where needed
- 394/394 tests passing

Watcher, REST endpoints, services (search, incidents, blocklist),
MCP server, context retriever, embedder, glean_scheduler, and
doc_upload all used the default 5-second SQLite busy timeout.
During collect glean write phases, watcher flush threads were hitting
'database is locked' errors when the glean held the write lock longer
than 5 seconds.
All connections now use timeout=30.0, matching the pipeline fix
from commit 6882248. No logic changes.
Ingest pipeline (journald / Caddy / Docker-wrapped formats) with
per-source state tracking (repeat dedup, out-of-order detection),
named pattern tagging at ingest time, and idempotent SHA1-keyed writes.
FTS5 search layer with porter stemmer, severity/source/pattern/time
filters, and BM25 ranking. MCP server (FastMCP stdio) with three tools:
search_logs, diagnose, list_log_sources — compatible with both
Claude Code and Copilot CLI.
WAL mode enabled on all connections. FTS index auto-built after ingest.
MCP configs included for Claude Code (.mcp.json) and Copilot CLI
(.github/copilot/mcp.json).
