Problem

The thread actions menu in the chat header (the chevron next to the title, or right-clicking the header) did nothing for an open thread that the shell snapshot leaves out. That's typically an older settled thread below the 25 most recently settled ones. No menu, no toast, so pin, un-settle, snooze, rename, archive and delete were all unreachable from the header. useThreadActionMenu.openMenu returned early when readThreadShell found no row, and nothing kept the open thread's row loaded: search results and the Settled shelf mount their rows only while they are shown.

Reproduced on main (e455200077) with the web dev server on a fresh database. I created 30 threads in one project and settled them 30 days ago through 1 day ago. Then I opened "Seed 00" (the oldest) from sidebar search, and separately by direct URL, and clicked the title chevron or right-clicked the header: nothing happened. The same click on "Seed 29" (recently settled, still in the shell) opened the menu.

Change

• ThreadRouteView keeps the open thread's family mounted (threadFamilies.mount) when the authoritative shell has no row for it. Once mounted, it stays until the route moves to another thread, so the row the family brings in does not release it. Threads that already have a shell row never trigger a family read. Every reader of the open thread's shell row (the header menu and the actions it runs) now finds it.
• If openMenu still finds no row (the family read is in flight or failed), it shows a "Thread actions unavailable" toast instead of returning silently.

Scope and approval

Fixes #32492

Verification

Tests

• New browser test opens the thread actions menu for an older settled thread the shell leaves out in apps/web/src/components/ChatView.browser.test.tsx. It renders the full app against the fake environment, which can now leave a settled thread out of the shell and serve getThreadFamily. With main's ThreadRouteView it fails because no "Rename thread" menu item appears; with this change it passes. The fake drops the row from the shell directly instead of going through the shellOlderSettled handshake. The client ends up in the same state as with a real omission (no shell row, family served), and the evidence below covers the negotiated path against a real server.
• vp test run src/components/ChatView.browser.test.tsx src/hooks/useThreadActionMenu.test.ts src/components/chat/ChatHeader.browser.test.tsx: 12/12 pass on the head merged with main.
• vp run check:changed: format, lint, knip, typecheck, tests and React compiler pass.

Evidence

Before d313b2a (main), after bf3f9f0. Each side runs as the real app on its own fresh database seeded with the same synthetic data: 30 threads in one project, settled 30 days ago through yesterday. The real shell cutoff leaves out Seed 00 and Seed 01 and lists Seed 29.

Every still, diff image, step timestamp and environment line is in the evidence index. The fixture matrix also lists the rows left out and why (menu contents, permissions and capabilities this diff does not change). Seed and driver scripts: seed.cjs, final-run.cjs, desktop-seed.cjs, desktop-capture.cjs, rebuild notes.

What else changed:

• While an older settled thread is open, its row appears under the sidebar's Settled section, and the heading moves up by one row. The row goes away when the route moves to another thread (R11).
• Actions run from the menu have their usual effects. Pin moves the thread into the pinned list and removes the settled banner. Rename updates the header and sidebar title.
• R07: a top-right toast, "Thread actions unavailable" / "This thread has not loaded yet.", shows while the family read is still in flight. This includes a click on a slow remote connection that lands before the read returns.
• Nothing else changes: R01 and R15 have zero changed pixels at zero threshold.

Not checked: native mobile is unaffected (its thread header has no thread actions menu). macOS's native menu shares the same Electron call that D01 drives on Linux.

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The change keeps older open threads available to the thread menu and shows an error when thread data is unavailable. It also adds a line-level lint suppression, which requires human review under the configured approval requirements.

Walkthrough

When a server thread is missing from the client after bootstrap, its route now mounts the thread family. The fake environment models older settled threads omitted from shell snapshots, and a browser test checks that the thread’s actions menu includes Rename thread.

Changes: Older settled thread actions

Layer / File(s)	Summary
Fake older-settled family reads apps/web/test/fakeEnvironment.ts	Fixtures can mark older settled threads. The fake server omits those threads from shell snapshots, preserves their settled status in shell and projection data, and returns shells for the requested thread’s root family. Server-config snapshots now use the dynamic config factory.
Route family mounting and menu coverage apps/web/src/components/ThreadRouteView.tsx, apps/web/src/hooks/useThreadActionMenu.ts, apps/web/src/components/ChatView.browser.test.tsx	After bootstrap, the route mounts the family for its server thread when the thread is missing. The menu shows an error when no shell is available. The browser test opens an older settled thread and checks that Rename thread appears in its actions menu.

The menu test uses a shell response production would not send. This limits fixture fidelity, but no production failure was established.

Make shell omission follow the advertised capability and request.

When an olderSettled fixture is installed, serverConfig() advertises shellThreadFamilies but not shellOlderSettled. The client therefore does not request omitOlderSettled. This handler still removes the row and supplies no olderSettled count. The browser test passes against a shell response that production would not send for that request, while the fake offers no settled-shelf path to the omitted row. Advertise and implement the older-settled omission contract, or keep the row when the request does not ask to omit it. (github.com)
