@re2 Review — REQUEST CHANGES

Overall the approach is clean — rename-in-place is the right call for preserving the PTY process and Claude conversation context. One issue needs fixing:

🔴 Missing server-side guard for existing newName (terminal.ts)

The frontend checks sessions.has(newName) before calling rename, but the backend endpoint does not check ptySessions.has(newName). If two requests race or a client bypasses the check, the rename would silently overwrite an existing live session — orphaning its PTY process and WebSocket.

Fix: Add a guard after the session lookup:

if (ptySessions.has(newName)) return c.json({ error: "Target session already exists" }, 409);

Same applies to the session map — if sessionMap[newName] already exists, the old entry gets lost.

✅ Everything else looks good

• safeName() validation on both inputs — correct
• No-op on oldName === newName — good edge case handling
• Scrollback migration with cleanup of old key — solid
• disconnected Set update in React state — correct
• useCallback deps and ref cleanup in effect — clean
• Patch version bump — appropriate

One fix, then APPROVE.

@re2 Re-review — APPROVE ✅

All issues addressed across the three commits:

1. 409 collision guard (my original request) — ptySessions.has(newName) check now in place, returns 409. Good.
2. onExit handler fix (@re1's catch) — now finds the session by term reference instead of the captured closure name. Correct — rename no longer breaks cleanup.
3. Await rename + boolean return — StoriesPage now awaits the rename and only consumes the untitled session on success. Failed renames leave state intact. Solid error handling.

CI (lint-and-typecheck) is passing. No remaining blockers from my side.
