Quarter goals
Team objectives. Quarter-level status to confirm; this update covers the sprint commitments and their progress.
Retro
Compared with the September 21–October 2 plan. Based on the async planning updates, with linked PR statuses refreshed on October 5. Merged code does not by itself mean rollout or outcome validation is complete.
Tasks
The main carryover is finishing the user workflow: surface useful work, make the next action clear, and verify the result after implementation. Evals and ranking now have more infrastructure behind them, but the personal inbox and outcome verification still need end-to-end validation. The first-run overload and personal inbox issues give that validation a concrete scope.
Unconfirmed from the previous plan: Olly's update is pending, so task-cost mapping, signal-text grouping, task-summary exposure, scheduled-task MCP work, and the question artefact work are not marked complete here. The network allowlist, anomaly-detector follow-ups, support scout, and customer Slack MCP rollout also have no explicit completion update in this round.
Plan
High priority
Low priority / side quests
Pending: Olly's and Chris's sprint updates.

Gustavo finished moving flags to the golden chart. All prod-us flags traffic now runs on it, the legacy releases, node pools, and IAM accounts are gone, and the PR canary runs on the new fleet. Phil moved flag call reads to the
flag_evaluationstable. The usage tab, activity page, projects tab, andlast_called_atcan now read from it behind a setting, a Dagster job backfills it from events, and orgs in flag-evaluations-only mode no longer write flag calls to events. Matheus deployed the realtime cohort pipeline to prod-eu, enabled it for team 1, and reduced the seeder's ClickHouse load. James shipped stale flag cleanup from the flag page, the MCP tools, and the cleanup skill, and the definitions cache now rebuilds an entry it served from S3. Patricio added flags evaluation charts to the public status page.Details
