From the multi-agent audit (ship-now, low-overfit-risk cluster):
INGESTION RESILIENCY
- client._request: 429/5xx now retry with Retry-After + exponential backoff
(previously hard-failed, feeding silent-stale ingest).
- SIP backfill feed (settings.backfill_feed='sip'): live realtime stays IEX, but
backtest/backfill ingestion uses the full consolidated tape — IEX sees only
~2-5% of true volume (verified: AAPL 22,797 vs 452,704), which was silently
corrupting every rvol/$-volume decision and backtest. eod_replay wired to it.
- step_ingest freshness watchdog: emits a STALE event + board note when the
newest bar is older than INGEST_STALE_SECONDS during RTH (45% of passes
historically returned 0 rows with no error). Optional hard arm-block
(INGEST_STALE_BLOCK, off by default).
RISK
- Portfolio gross-notional cap (TRADING_MAX_GROSS_NOTIONAL_PCT=0.60): both sizing
paths now cap each entry to the remaining gross budget, so 6 x 16% can't pile
the book into ~96% gross of correlated small-caps. Blocks/shrinks late entries.
- Fixed the duplicate TRADING_MAX_CONCURRENT_POSITIONS in .env.example.
MONITORING (UI)
- Naked/unprotected-position alarm: _unprotected_positions joins the latest
position + order snapshots (order sync now flattens legs) and the TUI board
shows a red UNPROTECTED banner the instant a held long lacks stop coverage —
the exact blind spot when APWC/NOWL went naked. Verified it flags today's
3 overnight positions.
Tests: gross-notional cap blocks when budget full; 50 pass.
