Two independent bugs left the near-close scan running on the previous
session's close, silently degrading live execution to the stale_close
floor (~1.57 Sharpe) instead of the intended ~1.77 close-fill case.
1. OHLCV window never covered the current day. Daily bars are stamped at
session start (04:00Z under EDT), so an end of midnight-on-end_date
landed before that day's bar and dropped it. Widening the window alone
fails the whole request with 'subscription does not permit querying
recent SIP data', so end is also clamped to now-20min. Today's bar is
now returned, roughly 20 minutes behind live -- within the staleness
the near-close design already assumed.
Intraday runs therefore store a partial bar and ingestion progress
reaches today, which made incremental resume skip the after-close
refresh entirely. collect_ohlcv_final() re-pulls the last sessions so
the consolidated bar overwrites the partial one before outcome eval.
2. APScheduler's from_crontab() passes day-of-week to its own field where
0=Monday, so '1-5' meant Tue-Sat: every Monday was skipped and the
scanner ran Saturdays on stale data. Weekday schedules now use names.
Stored settings already corrected via Admin; this fixes the defaults.
Tests cover both: today's bar inside the window, the delayed-data clamp,
historical windows untruncated, and a week of fire times asserting Monday
is present and weekends are not.

Diagnosing "no qualified signals for 5 days": setups were generated but none
qualified. The gate required BOTH a high min_rr (2.0) AND a high
min_target_probability (60), which became contradictory after the Jun-15
probability recalibration — probability already embeds R:R via the 1/(rr+1) ruin
term, so high-R:R targets are inherently low-probability and nothing cleared both.
Gate is now expected value (R): p*rr - (1-p) from the primary target's
probability. R:R and confidence stay as floors; high-conviction / exclude-conflicts
/ min-target-probability become optional tighteners (default off). Defaults:
min_expected_value=0.15, min_rr=1.2, min_confidence=55. EV is only enforced when
computable. Migration 009 clears stored activation_* rows so the new defaults
apply. Backtest sweeps min_expected_value instead of target probability.
Scheduling: pipelines are now cron-configurable in Admin -> Jobs. daily_pipeline
(full, default 0 7 * * *) plus a new light intraday_pipeline (OHLCV + outcome eval,
default hourly US session) that keeps prices/live-R:R current without setup churn.
Fundamentals on its own early weekly cron. Timezone configurable (default
Europe/Berlin). Moving interval->CronTrigger also fixes the restart-deferral bug
where an interval job's countdown resets on every process restart.
319 backend unit tests pass; frontend tsc clean.
