-- 2026-07-30 incident: post `2348` was retried 983 times by AI writer because automatic claim included `rewrite_status='failed'`; estimated internal cost was `$16.465977`. Live setting `ai_writer_enabled` was switched to `false` to stop spend. Automatic AI qualifier/writer claims must not include `failed`; failed posts require an explicit manual reset to `pending`. AI writer/qualifier now also set their own `*_enabled=false` after any failed AI batch, show the error on `/workers`, and send a Telegram alert via daily-report/TG-poster bot recipients, so one broken prompt/model/post cannot burn money indefinitely or fail silently.
