- v7.356 config: swap dataset_snapshot_id from manual_only ftb_fix_v2 to
auto_full_rebuild base canonical so paper trader can refresh snapshot
(root cause of processed_events=0 for 30 days)
- Multi-session order isolation (1.A.2/1.A.3): tag client_order_id with
pt-{session_id[:8]}-{uuid} prefix on all entry orders; _cancel_stale_orders
filters by own session prefix so one session no longer ghost-cancels another's
orders on shared Alpaca account
- Pipeline halt on failure (1.B.1): _run_pipeline returns bool and stops on
first subprocess failure instead of silently progressing with stale data
- Daemon restart window skip (2.2): run_open/run_close only marked completed
if processed_phases DB confirms prior execution — no more trading-less days
after mid-day restart
- event_parser: periodic batch commits every 500 docs (hypothesis fix for
3h hangs; unverified — may just be slow serial Oracle calls)
- Tests updated for _verify_order_fill tuple return + new cross-session
isolation test; all 23 paper_trader unit tests green

- screener: switch from non-existent single-ticker endpoint to multi-ticker
/alpaca/intraday batch calls (grouped by date, chunk ≤ 75); fixes 0-trades
- cache: bump version 2→3 to invalidate stale IEX Parquet files
- oracle_client: add get_multi_intraday_bars_today() for IEX real-time feed
- paper_trader: use /alpaca/intraday/today for live sessions, /alpaca/intraday
for historical (SIP)
- intraday.py: define _BUILTIN_STRATEGIES={} to fix /api/orb/strategies import
- delete orb_p1–p10_winner + variant configs; add strategies/orb_default.yaml
(Phase 10 params) as the single registered web strategy

- libs/oracle_client/alpaca.py: Added get_multi_daily_bars() and
get_multi_intraday_bars() helpers that call Oracle's /api/v1/price/data
and /api/v1/alpaca/intraday endpoints respectively. Oracle handles
symbol normalization (e.g. BF-B → BF.B) internally, so symbols like
BF-B no longer crash the screening chunk.
- apps/paper_trader/alpaca_broker.py: get_bars() and get_intraday_bars()
now use the new Oracle client helpers instead of the Alpaca SDK
StockBarsRequest, eliminating direct Alpaca bar API calls from broker.
- apps/orb_trader/engine.py: Removed per-symbol BF-B workaround (now
unnecessary since Oracle normalizes the symbol server-side); kept outer
try/except for chunk-level resilience.
