Slack mentions now start eyes reactions after the authorized task/comment commits, independently of attachments, subscription and scheduler acceptance. Omit unused optional URL-preview polling while retaining message text, links and files. Keep receipt failures and missing-file warnings independent, including terminal cleanup of older multi-line diagnostics.
Verified with full current-head CI and E2E, Superagent and legacy security checks, Apex 5/5 with no unresolved findings, 19 selected real-PostgreSQL receipt/authorization/cleanup cases, and full frozen-source typecheck/build. The first CI attempt's unchanged Cursor probe timeout is retained in the PR; the one failed-only retry passed under unchanged deadlines. Live Slack latency still requires deployed acceptance.
