The ONLY entry change that survived rigorous validation on 14 SIP-backfilled
sessions (53 trades). Gap-size buckets: 15-30% gap = +0.65R/trade, but 30-60%
blow-offs = +0.10R. Train/test split (70/30 by date): lowering TRIGGER_GAP_MAX
60 -> 35 lifts HELD-OUT TEST expectancy 0.194 -> 0.462 R/trade AND total R
(18.7 -> 19.9), better win rate, on both splits. Principled (huge gaps
fade/buy-the-top) and corroborated by the entry-timing audit (losers were
wide-range blow-off gappers).
Rejected after validation (do NOT ship): open-delay (forgoes total R for
marginal expectancy), breakout-HOLD/close-confirmation (hurts on the larger
sample), rvol floor (no-op: all gappers already rvol>=6). Confirmed KEEP: the
$-vol floor is fine on SIP volume (the earlier "it hurts" was corrupted IEX
data); profit-lock ladder stays.
.env TRIGGER_GAP_MAX 60 -> 35. NB: 14-day sample — re-validate as data grows.

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.

- Extract the cancel-protective-legs-then-close routine (duplicated in the exit
manager and the execution service after fixing the held-qty 403 in both) into
one shared, heavily-documented helper: runtime/flatten.py. Both callers now
delegate, so the fix can't drift out of sync. Behaviour unchanged; 121 tests
pass.
- Refresh .env.example: document every key added this session (liquidity gate +
sizing, backout cooldown, re-entry guard, managed-exit ladder, EOD flatten)
with the why, and flag MAX_DAILY_LOSS_PCT to revert to 0.03 before live.
- Remove throwaway data/_watch_*.py monitoring scripts (gitignored clutter).

Sweep over 172 real gapper sessions (16 days) with a per-setup breakdown found
the opening-range breakout is the ONLY profitable setup (+0.25R); every slow
pattern loses (bull_flag -$78k @ ~42min is the worst). Running ORB-ONLY flips
the book from -$95k to +$7.4k AND enters ~11 min earlier (23 vs 34 min avg).
- classify_setup prefers the ORB when valid and honors STRATEGY_SETUPS env
(comma-sep setup values) to restrict active setups; .env defaults to
STRATEGY_SETUPS=opening_range_break (ORB-only).
- BacktestEngine Trade.setup_type captured for per-setup attribution.
- learn_params load_sessions filters to gapper sessions (mimics live scanner) so
the backtest trades the same universe the system would.
75/75 tests green.

- grafana/: docker-compose + provisioned Postgres datasource + 'Momentum — Live'
dashboard (evaluation board with status colours, ready signals, risk events,
bars + equity timeseries) reading the event store via JSONB extraction.
Run: cd grafana && docker compose up -d -> http://localhost:3000.
- RSS news-catalyst discovery wired: extract_tickers also matches $CASHTAGS;
run_discovery pulls tickers from recent news into the universe when NEWS_FEEDS
is set (no-op / safe otherwise).
- docs: .env.example NEWS_FEEDS; GO_LIVE monitoring adds 'momentum watch' + Grafana.
67/67 tests green. Live board (momentum watch) verified rendering the evaluation
board with real determinations.

- Drop duckdb dependency (pyproject, requirements) -> psycopg2-binary.
- run_live_paper: boot log shows the real Postgres target (masked); add
_db_target_desc() helper.
- .env.example: document DATABASE_URL / PG* vars; mark WATCHER_EVENT_DB_PATH legacy.
- evaluation/storage.py: INSERT OR REPLACE -> INSERT (setup_id is a fresh uuid).
Verified: 67/67 tests green on Postgres with duckdb UNINSTALLED; app boots
against the live endpoint (127.0.0.1:5432 proxy) and wrote 205 daily bars.
