Two lifecycle holes the registry and the consumer helper left open.
`AdapterRegistrationHandle.replace` had no liveness guard: after the handle's
disposer ran, a replace put routes back into the registry with nothing left to
release them, so the adapter leaked permanently. `owned` being empty cannot
carry that fact, because `replace([])` is the legal empty-section state, so the
disposer records it explicitly.
`installSettingsSection`'s watcher lacked the guard its own disposer carries:
a stored change landing while the consumer unloads reached `onChange`, which
re-registers routes against a fiber whose resources are being released.
Also documents `withFileLock` in the atomic-write README (it claimed one
export), records the age-based lock takeover as a known limitation, and lists
ctx.settings and ctx.credentials in the architecture capability table.
Keep only groups with another path in the active round. This bounds skewed sampling by paths visited instead of rescanning every singleton for every late-group item.
- built-boot smoke asserts [data-variant=web][data-tool=web_search/fetch]
(the keyed WebRow) instead of [data-web] (which WebBlock draws even on the
GenericToolCard fallback, so a silent keyed-registration failure passed).
- WebBlock renders an explicit empty-state note when a search returns no
answer and no sources, instead of a blank <ol>; the chat row does not
surface the raw result content, so the backend's 'No results found.' was
otherwise invisible.
- README (ui-conversation, ui-primitives) and the frontend Agent Note record
the unknown-web-kind null arm, the details-panel flattened body, and the
empty-search copy; pairings re-recorded.
The coverage lane flagged transcript.ts line 63 (diffContentLines' empty-text
return) uncovered: the same-file diff test only fed newline-terminated sides.
Add a third hunk removing a line with an empty added side (a full deletion), so
the empty arm runs and the footer proves the empty side draws no `+ ` row
(+2 -1 · 1 file). Raise the test's line budget so every hunk row stays visible.
boot() asserts over ctx.loader after awaiting the Loader, but the TUI renders
as soon as its own fiber starts: an /exit typed before the last entry settles
runs disposeRootAndExit, which takes the Loader service with the tree. The
assertions then read undefined and crashed the process with a TypeError over
an app that exited exactly as asked. The keyless personal-overlay PTY smoke
lost this race in roughly two of three runs.
