+- **?ui=<mode> is an opt-in too — the gate had killed every shared mode link (v4.6.163)** `7efece4`
+  - v4.6.162 shipped the opt-in gate as `get('ui') === '1'`. But the UI shell has always treated `?ui=<mode>` as a REQUEST — `module-uishell.js` reads `q = get('ui')` and honours it when the value is one of `lazyIds()` (easy|chat|studio|workspace|commander|cockpit), with `_fromQuery` set so the request never becomes a stored preference. So every shared link of the form `main.html?ui=chat` stopped mounting the shell entirely and booted classic, silently, with no error: the gate required a literal '1' that the shell's own convention never sends.

 - **Re-enable the six UI modes behind an opt-in gate (v4.6.162)** `4b280ed`
   - The six interface modes (v4.6.152–156) were removed from the startup path outright in v4.6.157 after crash reports. The crash was never reproduced: F2 in the rollback plan (2026-11-09_224409) drove all six modes on one page in headless Chromium at 390×844 and recorded crashes: [], pageerrors: [], heap flat at 10 MB over a 25 s idle. The two defects the investigation DID find were fixed instead — F3 (nginx 413 on a >1 MB agent context) and F4 (36 tool handlers where a model-supplied non-string reached .trim/.split/.replace). v4.6.159–161 also removed the last navigator.onLine verdicts, which is what made "it died mid-session" look like a UI crash.
