- webapp/: deployable LAMP app for /var/www/ — ingest.php (token-gated writes), api.php (public read-only), schema.sql (live_price + signal_reports), vanilla-JS dashboard with plain-English indicator readings, .htaccess, deploy README - web_publisher.py: fire-and-forget publisher (bounded queue + daemon thread) with plain-English payload builder; public API contractually never raises; disabled unless WEBAPP_INGEST_URL/TOKEN are set - telegram_bot.py: publish hooks (tick in WS loop, report in _update_level_cache); _candle_loop per-iteration guard so a failing scan can never kill an auto-scan loop; quiet heartbeat teardown - test_all.py: Module 13 — 6 resilience tests (never-raise contract, worker survival, candle-loop survival); suite 189/189 - .gitignore: webapp/config.php (server-side secrets) Verified end-to-end on a scratch MariaDB 10.11 + PHP 8.3 built-in server incl. headless-Firefox render of the live page.
