M5 already broadcast through the shared _scan_timeframe path but was
documented as data-only (docstring, CLAUDE.md, DOCUMENTATION.md, plus a
phantom `if tf == M5: return` step that never existed in code). Align all
docs/comments so M5 alerting at C+ grade is the intended, documented behavior.
Remove the live dashboard entirely per request: the 30s refresh loop,
per-scan refresh, boot send, and the dashboard-only stats layer
(_signal_stats / _stats_updated / _update_signal_stats and its call sites,
_format_stats_dashboard and its helper constants). Drop now-unused ZoneInfo
import and dashboard mentions from help/autoscan/boot messages and the test
suite. The WebSocket level-breach monitor and level cache are untouched.
Tests: 136 passed, 0 failed.
The old `weekday() >= 5` check blocked all of Sunday, but the forex
market reopens Sunday 22:00 UTC (Sydney open). Now uses proper time-based
check so the bot fetches data and generates signals on Sunday evening.
- Move index dedup before OHLC consistency fix in _validate_and_clean
to prevent crash when df.loc[dup_idx] returns Series instead of scalar
- Add global flood backoff: detect RetryAfter, pause all sends/edits
until ban expires instead of retrying and escalating the ban
- Stop dashboard edit-fail → new-message spam cascade: track consecutive
failures, only resend after 3 failed edits
- Increase dashboard refresh from 5s to 30s, min send interval to 1.5s
- Add comprehensive QA test suite (140 tests across all 7 modules)
