fix(ui): keep titles readable on phones and clear a stale approval after a failed run - #52

Conversation
…ter a failed run - Thread list: below md the four per-thread icons collapse into one 44px "..." menu so the title keeps the row; desktop keeps the hover toolbar. Closing a dialog opened from the menu returns focus to the row's trigger. - File preview: stack the title over the toolbar below sm, make the title visible and give it initial focus, size the dialog in dvh, 44px targets. Dialog close button is 44px below sm. - useChat: a failed or cancelled run keeps `next` populated, so the recovery poll never cleared the approval the SDK still held and the composer stayed locked. Clear it once the server reports the thread settled with no actionable interrupt; suppression stays keyed to that interrupt's id. - Add @radix-ui/react-dropdown-menu, locked at 2.1.16 so its Radix internals dedupe with the installed dialog and select. - .prettierignore: skip .codex-qa/.

Suggested reviewers: Merge Risk: 🔵 Low · up to Mobile users can encounter title overlap or lost focus after resizing, and future installs may select a different dropdown version. These are bounded issues but should be corrected before merge if the stated version lock and accessibility behavior are required. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

2.1.16 instead of using a caret range, then regenerate the corresponding
lockfile so it reflects the pinned version.
In `@src/app/components/ThreadList.tsx`:
- Line 347: Update restoreMenuFocus in ThreadList so that when the mobile
trigger is hidden, it focuses the thread row’s selectable button instead of
returning. Preserve the existing trigger-focus behavior when the trigger remains
visible.
In `@src/app/components/WorkspaceFileDialog.tsx`:
- Line 281: Increase the mobile right padding on the title row from pr-8 to
pr-10 while keeping sm:pr-0, so long titles truncate before reaching the close
button.

Use the exact dependency version.
^2.1.16 permits later 2.x releases. This range does not satisfy the PR requirement to lock version 2.1.16.
Set the version to "2.1.16" and regenerate the corresponding lockfile.

If the viewport crosses md while a dialog opened from the "..." menu is open, the trigger is display:none and Radix's own restore target (the menu item) is already unmounted, so focus fell to <body>. Fall back to the row's select button. Also give the file preview title 8px more clearance from the 44px close button below sm.

What & why
A browser pass over the UI at 1440 / 768 / 390 / 320 px turned up three problems. Two are phone layout, one is a chat lock-up that happens at any width.
DropdownMenu, newsrc/components/ui/dropdown-menu.tsx); the title gets the row back and the row stays one line tall. Desktop keeps the hover toolbar unchanged. A dialog opened from the menu has no opener left to return focus to — the menu item unmounts with the menu — so closing Rename / Delete hands focus back to the row's "⋯" trigger instead of dropping it on<body>(or to the row itself if the viewport grew pastmdmeanwhile and the trigger is hidden); dialogs opened from the desktop toolbar keep Radix's own restore.sm, the title is the real (visible)DialogTitleand takes initial focus instead of the Delete button, the dialog usesdvhso it fits short screens, and toolbar buttons are 44 px. The shared dialog close button is 44 px belowsm, andDialogHeaderleaves room for it.useChat). Approve anexecute, the tool finishes, then the model call after it fails (seen live with a provider 429). The server ends withstatus: "error",next: ["model"]and no interrupt on any task, but the SDK still holds the approval that was just resolved — the page showed "Approval requested by a sub-agent" and the composer stayed locked until a reload. The recovery poll only cleared a stale approval whennextwas empty, and a failed or cancelled run keepsnextpopulated for good. It now also clears it when the server reports the thread as settled (idle/interrupted/error) with no actionable interrupt. Suppression is still keyed to that one interrupt's id, and the bounded follow-up polling continues whilenextis populated, so a genuinely new approval — same arguments included — still shows..prettierignore: skip.codex-qa/(local QA evidence, already git-ignored; Prettier 2 does not read.gitignore, soformat:checkfailed locally once the folder held JSON).New dependency:
@radix-ui/react-dropdown-menu@^2.1.16, resolved to 2.1.16 in the lockfile on purpose (caret like the other Radix packages, so the family keeps moving together; pinning only this one would strand it on old internals the next time dialog / select are updated). That release shares its internals with the installedreact-dialog@1.1.15/react-select@2.2.6, sodismissable-layer,focus-scope,popperandportaldedupe to one copy (lockfile: +119 lines, 3 packages). The current 2.1.24 nests ~35 duplicate Radix internals; those coordinate layers and focus through module-level state, so a menu and a dialog on separate copies would not see each other.Manual testing
npm run lint && npm run format:check && npm run buildall green (alsotypecheck;npm test: 492 passed, up from 481, under Node 20 and Node 25)npm run build && npm start; dev and standalone behave differently)Test steps / screenshots
On a phone, or DevTools at 320–390 px with touch emulation:
execute, approve it, and have the following model call fail (a rate-limited provider does it). The approval card goes away on its own and the composer is usable without a reload.Thread-list menu, driven in headless Chrome (320×740, touch emulation) against a live backend on a throwaway thread:
display: nonepointer-events: noneleft on<body>, page takes inputStale approval: reproduced live (real
execute, then a 429 on the next model call), fixed, and re-checked in the same session. Control run for the regression tests: withuseChat.tsfrommain, the three newrecoveryPollcases (error/interrupted/idle) fail; with this branch they pass. Mutation check on the new tests: eight mutants (menu item wired to the wrong handler, pin label ignoringpinned, no prefill, focus not restored for Rename / Delete, suppression no longer keyed to one interrupt, polling stopped once settled,busycounted as settled) — all eight fail the suite.Not covered live: a sub-agent approval and parallel approvals under the new settled-status rule — provider rate limiting cut the session short, so these rest on
recoveryPoll.test.tsxonly. The rule relies on a pending sub-agent interrupt being visible on the root thread'stasks[].interrupts. That holds by construction in LangGraph 1.2.11 — aGraphInterruptleaving a task is written as anINTERRUPTagainst that (parent) task's id (pregel/_runner.py,commit()), and the state snapshot buildstasks[].interruptsfrom those writes — but it was read from source, not exercised; worth one live sub-agentexecuteapproval before release. Also not covered: a physical phone (soft keyboard, real touch), and the production build beyond compiling — the live checks ran againstnext dev.Known leftover, not addressed here: the Knowledge graph is crowded at 320 px (189 nodes, overlapping labels).
