Write & POST May 27 standup to Slack (12:30-13:30 UTC window) — direct auth/dashboard burst + #10870 landed

Daily standup task per LEARNINGS 2026-05-27 04:10 UTC reflection and AGENTS.md End-of-Reflection Wiring Audit item (3). Posting window: 2026-05-27 12:30-13:30 UTC. DoD: Slack DM to Carson (channel D0B0980TR88) + memory/standups/2026-05-27.md. MANDATORY final-refresh step before send: re-read fleet-task resume, Slack DMs/assistant-thread messages since 2026-05-27 02:07 UTC, latest PR truth for #10870/#11189/#11190/#11191/#11198 and older backlog (#9886/#9932/#9353/#10401/#10498/#10499/#10508/#10824), and any review/check state on #11190 or newly opened auth/dashboard PRs. Patch memory/standups/2026-05-27.md so no stale claim survives. In particular, do not imply #11190 is done unless it merged or was explicitly closed/superseded. Content draft: May 26 standup posted inside window; #10870 merged; direct Carson asks produced PR #11189 merged, #11191 merged, #11198 merged; #11190 draft-time state is open/conflicting and requires final-refresh/superseded-vs-repair call; older backlog remains hold/report-only unless truth changed. No broad allocation prompt unless Carson replied or PR truth materially changed. Send-side timing/status guard: do not send before metadata.trigger_after_utc or 12:30 UTC. If task is leased early, renew/checkpoint or leave queued rather than waiting silently past the 5-minute lease. After successful Slack send, immediately PATCH this task to completed with slack_ts, delivered_at, and memory_file before any other work. Topic for ping-lockout bookkeeping: standup-may-27. CHECKLIST-CONTACT Gates 1-8 must run before send. Pre-staged body path: memory/standups/2026-05-27.md
