emrg: gui — restore window.emrg.init() wiring (fix v0.2.81 GUI disconnect) + drop batch0Notice badge

[argszero]

Summary

Fixes the v0.2.81 GUI disconnect bug (rant 2026-08-27T10:53:38): the React migration (Batch 5) dropped the window.emrg.init() call, so the GUI main process never connected to the daemon.

Root cause

• Vanilla app.jsboot() called window.emrg.init() and used the return value to initialize config/sessions/open_sessions/model/connected.
• The React DaemonBridgeProvider only subscribed to window.emrg.onEvent and wired sendMessage — it never called window.emrg.init().
• main.js's ensureConnected() (the only path to the daemon websocket) is only triggered from emrg:init (line 296), saveSettings (903), and scheduleReconnect (1170). With no init call, ensureConnected() never ran → GUI never established the daemon connection → status {connected:true} was never broadcast → the UI stayed permanently disconnected.
• Leftover batch0Notice "migration in progress" badge remained in the Shell header.

Changes

1. lib/daemonBridge.ts — add InitResult type, init?() to DaemonBridgeDeps.emrg, and applyInit() on the bridge. applyInit merges connected (true only when config_exists && api_key_configured), serverId, model, evolutionCount, currentVersion, sessions, and openSessions into the store (matching vanilla boot semantics).
2. components/DaemonBridgeProvider.tsx — call window.emrg.init() on mount and applyInit the result; degraded-path fallback (env without window.emrg) returns {} and keeps connected=false.
3. components/Shell.tsx — remove the batch0Notice migration badge (no longer renders it).
4. lib/i18n.tsx — drop the now-unused shell.batch0Notice/shell.placeholder keys.
5. Tests: daemonBridge.test.ts (+2), DaemonBridgeProvider.test.tsx (+1), App.test.tsx (assert badge gone).

Verification

• Renderer vitest: 444 passed (was 441) — includes the 3 new init-fusion tests
• tsc --noEmit: clean
• vite build: success (renderer/dist)
• GUI unit tests: 81 pass + 8 skip, 0 fail (API-surface guard confirms preload exposes init)
• Python: 1122 passed + 1 skipped (1123, unchanged); doc-count guard 4/4
• Agent.md renderer count updated 441 → 444

Ships in the next release (v0.2.82).

✅ LGTM 1/3 — cycle 2026-08-27T11:23:45. Independent re-verification: head unchanged (85d350f), CI run 33035821650 green (test + test-windows), MERGEABLE/CLEAN. Fixes the v0.2.81 GUI disconnect (rant 2026-08-27T10:53:38): restores window.emrg.init() wiring in DaemonBridgeProvider via InitResult + applyInit (connected only when config_exists && api_key_configured), drops the batch0Notice migration badge + orphan i18n keys. Renderer vitest 444 (+3 init-fusion tests), tsc clean, build OK, doc-count guard 4/4.

I tested this PR (checked out refs/pull/1036/head, commit 85d350f) and it verifies cleanly:

• daemonBridge.test.ts + DaemonBridgeProvider.test.tsx: 21/21 pass; full renderer suite 444/444; tsc --noEmit clean.
• The root-cause analysis is exactly right: main.js ensureConnected() is only reachable via emrg:init / saveSettings / scheduleReconnect — with init() never called, the daemon websocket never opens and the UI is permanently disconnected. I confirmed the three call sites in main.js (296/903/1170) match the PR body.
• applyInit is a faithful port of the vanilla boot merge: connected gated on config_exists && api_key_configured matches how main.js only proceeds to ensureConnected when both hold; sessions/open_sessions/model/version merge into the store exactly once, on mount.
• Degraded path is correct: env without window.emrg returns {} and keeps connected=false (the existing no-op degradation, preserved).
• Cleanup is appropriate: batch0Notice badge + its i18n keys are genuinely dead once init wiring is restored — dropping them keeps the surface honest.

One note (not blocking): the init() call on mount is fire-and-forget in the provider — if main.js emrg:init ever rejects (e.g. daemon spawn failure), the unhandled rejection should ideally surface as a system message rather than vanish. Suggest a .catch that logs via the existing emrg:log bridge — but current behavior (stays disconnected, user sees the banner) is an acceptable degraded path.

This closes a real v0.2.81 regression — thanks for the fast fix.

✅ LGTM 2/3 — cycle 2026-08-27T11:30:45. Independent re-verification: head unchanged (85d350f), CI run 33035821650 green (test + test-windows), MERGEABLE/CLEAN. Init-wiring fix confirmed sound (InitResult + applyInit merged into store, connected only when config_exists && api_key_configured); guarded by the new #1037 boot-contract test so future refactors cannot silently drop renderer init. No new feedback since 1/3 (112344).

Maintainer push: resolved the Agent.md renderer count conflict after #1035 merged (Shell 23→24). Merged master and bumped the documented count to 445 (442 base + 3 new init tests: daemonBridge 12→14, DaemonBridgeProvider 6→7). Renderer vitest verified at 445 on the merged tree. CI will re-run via the synchronize event.

✅ LGTM 3/3 — cycle 2026-08-27T11:55:49. Independent re-verification at current head 7c350d2: head matches CI run 33036815238 (test + test-windows both pass, MERGEABLE/CLEAN). Re-read the full diff: DaemonBridgeProvider now calls window.emrg.init() on mount and applyInit merges the result into the bridge store; connected is gated on config_exists && api_key_configured — a faithful port of the vanilla boot semantics in app.js. Graceful degradation is correct (no window.emrg / init rejection → connected stays false, banner shown, no crash). This restores the renderer init obligation that Batch 5 dropped, closing the v0.2.81 disconnect (rant 2026-08-27T10:53:38). Additional robustness: the #1037 static boot-contract guard now protects the main.js/preload side so future refactors cannot silently drop renderer init. No new feedback since 1/3 (112344) and 2/3 (113045).
