p2 rewritten by the Chord v2 authoring rules (decision "App authoring rules confirmed by the p2 audit"), in four parts merged together: - core: session lifecycle (relocate, clone, fork, archive) and search rebuild are persisted jobs on a new server store; Sessions v6 with client-chosen ids and visible operations; Retry answers with the worker's real outcome; workers push branch, subagent and status state to the server; roots take the method's ctx. - services: models, envs, ports, login, mcp, logs, sharing and voice follow external state (self.follow, followNative) instead of copy loops; methods answer after their state commits; presence from host.references. - chat: chat mode, artifacts and prompt resources follow Durable and native state; shell commands are Chord jobs (shellId is the requestId); status pushed before send and stop answer; race-free draft claim. - ui: optimistic updates on web (useOptimistic) and terminal (TuiScope.optimistic, extended in Chord with a reducer and a pending flag), pending states for long work, visible rollback, load waterfalls removed; merged with the one composer and immediate first send (ccff9876e) and the folder + button (5a31a6d5f). docs/optimistic-ui.md describes the pattern.
