Prioritized P0->P2 plan to make the system cleaner + easier to troubleshoot,
produced by a 4-agent read-only mapping pass (no code changed). Key findings:
- Single-Postgres migration is FUNCTIONALLY COMPLETE at the connection layer
(all live code -> storage/db.py -> db_pg -> one DATABASE_URL Postgres; no
live duckdb.connect). Datastore work is cleanup, not architecture.
- The real architectural item is the TWO entry paths. The live (auto) path is
missing five fast-path-only gates: extension, day-extension, halt-guard,
liquidity-sizing, rank — a REAL current gap (47/47 of today's fills were
approved_by="auto"). Root cause: the ready-signal snapshot carries no live
price/day_open/volume/rank. Fix sequenced behind a flag, reversibly.
- Dead-code/cleanup: core/ + telemetry/ packages (zero callers), archive/ tree
+ 232MB zip (gitignored), dead schwab/ integration, an orphaned mem_ test
schema left in prod Postgres.
