emrg: GUI open-sessions sidebar shows title for cross-project sessions (rant 2026-08-14T12:01:44)

[argszero]

Summary

Host rant 2026-08-14T12:01:44: in the GUI "open sessions" sidebar region, cross-project opened sessions show only the session id even when the session has a name/title. Current-project sessions are unaffected (they resolve via App.state.sessions).

Root cause (verified)

• renderOpenSessions (sidebar.js) looks up titles only in App.state.sessions, which is populated by list_sessions(cwd=projectDir) — i.e. only sessions of the current global project dir.
• openSessionsList() (main.js) entries were {sid, projectName, projectPath, lastActive} — no title field.
• → Cross-project opened sessions (e.g. an emrg-evolution-emrg-task session opened while the global project dir is ~/.emrg) are missing from state.sessions → cur = {} → title falls back to entry.sid.

Fix

• main.js: listSessions(cwd = projectDir) gains an optional cwd param; touchOpenSession asynchronously fetches the session's own project list (listSessions(projectPath)) and sets v.title when found (fail/no title → stays undefined → sid fallback); openSessionsList() now includes title; renameSession handler syncs v.title + rebroadcasts after a successful rename.
• sidebar.js: title priority chain entry.title || cur.title || entry.sid (entry.title wins for cross-project, cur.title for current-project, sid last).
• test: new renderer.smoke case covering all three branches (cross-project entry.title shown, no-title+unknown-sid falls back to sid, current-project still resolves via state.sessions).

Verification

• GUI npm test: 245/245 pass (120 renderer smoke, was 119).
• Python: pytest 804 passed; import + CLI checks green; doc-count guard (test_doc_counts.py) 3/3.
• Agent.md GUI breakdown synced 244→245.

✅ LGTM — cycle (verified locally: pytest 804 green, GUI npm test 245/245 with the new cross-project title test, import + CLI checks pass; CI test + test-windows both PASS on this PR; diff matches the rant 12:01:44 spec: entry.title || cur.title || entry.sid priority chain + async per-project title fetch in touchOpenSession + rename sync)

✅ LGTM — cycle (2/3)

Reviewed on rebased head 319c649 (conflict resolved after #781 merge: merged master in, kept Agent.md GUI 245 — rebase dropped #781's already-merged commit, GUI delta unchanged).

Verified GUI delta (4 files, +49/-6):

• main.js: rename_session success → immediately sync openSessions[sid].title + broadcast; touchOpenSession → async per-project listSessions(projectPath) fetch, sets v.title + broadcast if found (fail → undefined → sid fallback); openSessionsList() passes title through; listSessions(cwd=projectDir) parameterized for cross-project query.
• sidebar.js: title priority chain entry.title || cur.title || entry.sid — cross-project entries (not in current project's state.sessions) now resolve via entry.title instead of raw sid.
• New smoke test (3 states): entry.title present → wins over sid; cross-project no title → sid fallback; current-project → state.sessions title. Discriminating, not smoke-only.
• Agent.md GUI 244→245 synced.

Local: GUI npm test 245/245 (incl. new test) + pytest 804 green. CI test + test-windows re-running on new head (watch). MERGEABLE.
