emrg: GUI rant panel + list_rants daemon command (rant 2026-08-13T14:10:14 P4)

[argszero]

GUI redesign (host rant 2026-08-13T14:10:14) — P4 rant panel.

The sidebar Rant nav entry now opens a functional rant management panel (previously a placeholder).

Daemon (new capability)

• list_rants command: reads ~/.emrg/rants.jsonl, optional status filter (pending / in_progress / completed / "" = all), newest-first order, corrupt lines skipped, missing file → empty list (never crashes). Response frame rants_list.

GUI

• Rant panel with 4 status filter tabs (全部/待处理/进行中/已完成) — each re-queries the daemon with the status param.
• List rows: timestamp + status badge (zh/en) + project + progress snippet; clicking a row expands a detail section with full message + full progress.
• 新建 Rant form: project dropdown (listProjects) + message textarea → sendRant (existing IPC), success toast + list refresh.
• openRantsPanel() lazy-loads on nav open (same pattern as P3/P5 panels); i18n zh/en rants.* keys (incl. data-i18n-placeholder for the textarea, satisfying the Stage-3 Chinese-string guard).

IPC chain

• main.js emrg:listRants handler + preload.js listRants; daemon_client.js RESPONSE_TYPES list_rants → rants_list.

Tests

• +2 pytest (list_rants filter/order/corrupt-skip + missing-file): 777→779.
• +1 renderer smoke (list + status badges + detail expand + filter passthrough + new-rant submit): GUI 235→236 (renderer smoke 113→114).
• +1 assertion in RESPONSE_TYPES mirror test (list_rants → rants_list).
• 779 pytest + 236 GUI + import + CLI + doc-count guard all green locally; CI pending.

Reviewed the full diff for P4 (rant panel) of the GUI redesign (rant 14:10:14):

• Daemon list_rants: reads rants.jsonl with optional status filter, newest-first, corrupt lines skipped, missing file → empty — 2 pytest tests cover filter/order/corrupt/missing.
• GUI panel: 4 status filter tabs (re-query with status param), rows with timestamp + status badge + project + progress snippet, click-to-expand detail (full message + progress), new-rant form (project dropdown + sendRant reuse).
• IPC chain complete: main.js handler + preload + RESPONSE_TYPES list_rants → rants_list (+1 mirror-test assertion); lazy-load on nav open matches P3/P5 pattern; i18n zh/en incl. data-i18n-placeholder (Stage-3 guard satisfied).
• Verified locally: 779 pytest + 236 GUI + import + CLI + doc-count guard green; CI test + test-windows PASS (31679974507), mergeStateStatus CLEAN.

Reviewed full diff for P4 (GUI rant panel + list_rants, rant 14:10:14, 367+/5-):

• daemon: list_rants reads _rants_log (daemon.py:176, same file the rant command writes), optional status filter ('' = all, old entries default 'pending'), newest-first sort, corrupt lines skipped, OSError → empty + error frame. +2 tests (filter+order+corrupt-skip, missing-file).
• main.js: emrg:listRants IPC with status validation + 5s timeout; preload/daemon_client wiring; RESPONSE_TYPES list_rants→rants_list (protocol mirrored + tested).
• renderer: rant panel with 4 filter tabs, list rows (timestamp/status badge/project/progress), click-to-expand detail (row.after — test stub updated to real sibling insert), new-rant form (project dropdown via listProjects + sendRant), openRantsPanel follows openTasksPanel pattern.
• i18n: 17 zh/en keys, consistent naming.
• Verified: 2 new daemon tests pass, 779 pytest collected, npm test 236/236 pass, node --check OK, doc-count guard green, CI test+test-windows SUCCESS (31679974507), mergeStateStatus CLEAN.
