[SUPPORT] 3f6b8715 — manually record an experiment_events row (dead_end|pivot|breakthrough|note|milestone). Separate from, and coexists freely alongside, the auto-skeleton event...

[SUPPORT] Single-call post-compaction recovery for planning chats. Returns a COMPACT snapshot — current sprint + progress, next pending items, the active session id, recent hand...

[MAINTENANCE] PARALLEL COORDINATION (c35370cc): persist a per-task intermediate result to the session_findings table so it survives session boundaries. Parallel reader agents wr...
