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.
Each branch is a top-level conversation forked from another at an entry;
the session-scoped p2.main document lists them and names the current one.
Earlier branches are read-only. The main agent's per-agent state
(subagents, artifacts, voice and chat mode, pending move) stays on
conversation 1 for every branch.
- tree plugin: SessionTree (tree, navigate, select); the worker reports
main and branches to the catalog (Sessions v4, catalog schema 4)
- TUI: /tree and double Escape (pi's default "tree"), a tree selector
adapted from coding-agent
- web: Edit on user messages, Branch from here on answers, branch rows
under the session in the sidebar
- main-agent checks use the branch list instead of conversation 1
- search indexes each branch's own entries
Design: apps/p2/docs/tree.md
p2 (Pi Mobile on Chord v2) moves from pi-private into pi as one commit. Root scripts that loop all workspaces
use --if-present; npm test, ./test.sh and the release script cover packages/* only (p2: cd apps/p2 && npm test);
sync-versions also updates apps' workspace pins.
