Write & POST May 29 standup to Slack (12:30-13:30 UTC window) — PR #11281 landed; two decision prompts still open

Daily standup task per LEARNINGS 2026-05-29 04:10 UTC reflection and AGENTS.md End-of-Reflection Wiring Audit item (3). Posting window: 2026-05-29 12:30-13:30 UTC. DoD: Slack DM to Carson (channel D0B0980TR88) + memory/standups/2026-05-29.md. MANDATORY final-refresh step before send: re-read fleet-task resume, latest Slack DM/assistant-thread messages since 2026-05-28 19:07 UTC, latest PR truth for #11281/#11190/#11191/#11198/#10870/#11189 and older backlog (#9886/#9932/#9353/#10401/#10498/#10499/#10508/#10824), active-ci-watch.env, and any new auth/identity work Carson started. Patch memory/standups/2026-05-29.md so no stale claim survives. In particular: do not re-surface Sergey SSO or #11190 prompts if Carson answered them in the meantime; do not imply #11281 is still open if a later state appears. Content draft: May 28 standup posted inside window; Carson direct ask on PR #11281 CI fixes completed and merged at 21:04 UTC; Sergey SSO + #11190 decision prompts remain unanswered as of draft; older backlog hold/report-only. 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-2026-05-29. CHECKLIST-CONTACT Gates 1-8 must run before send. Pre-staged body path: memory/standups/2026-05-29.md
