DottaandClaude Opus 5.5 8004ad069e perf(ui): skip socket reconcile for reads that have no live events (#20398)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The board UI keeps company data fresh through `LiveUpdatesProvider`,
which listens on a WebSocket and invalidates queries for each event
> - The provider closes the socket while the tab is hidden, and events
are not replayed, so it invalidates every active query when the socket
opens and when the tab returns
> - Some of those queries have no live events at all: instance settings,
plugin UI contributions, and the person's workspace and sidebar
preferences
> - Reconciling them adds requests to every tab return and to the first
socket open, on a server that is already saturated
> - This pull request excludes those reads from the reconcile and gives
them a 5-minute stale time
> - The benefit is four fewer requests on each tab return and on the
first socket open, with no change to company data freshness

## Linked Issues or Issue Description

**What existing behavior does this improve?**
The burst of requests when a board UI tab regains focus, and the second
wave right after page load.

**Subsystem affected**
Board UI live updates (`ui/src/context/LiveUpdatesProvider.tsx`) and
query defaults (`ui/src/main.tsx`, new `ui/src/lib/live-reconcile.ts`).

**Current behavior**
On a local instance, returning to a hidden Mine tab sends 27 API
requests. Those include `instance/settings/experimental`,
`workspace-preferences/me`, `plugins/ui-contributions` and
`sidebar-preferences/me`. Live events never touch these. The same four
re-fire when the socket first opens after load.

**Proposed behavior**
The socket reconcile skips those four reads. Their stale time is 5
minutes, so a window-focus refetch runs at most every 5 minutes. Their
own mutations still invalidate them at once.

**Reason and benefit**
Each tab return costs four fewer requests. On staging, about 25 requests
re-fire together on focus, and every one delays the visible rows.

## What Changed

- New `ui/src/lib/live-reconcile.ts`: `LIVE_EVENT_FREE_QUERY_KEYS`
(instance settings, general and experimental settings, plugin UI
contributions, workspace preferences, sidebar preferences),
`isLiveReconciledQuery`, and `applyLiveEventFreeQueryDefaults`.
- `LiveUpdatesProvider` passes `isLiveReconciledQuery` as the predicate
on its invalidate-all paths: tab return, disconnected polling, socket
open, `live.resync`, and the transcript recovery that runs after a
resync. The first healthy open still also skips session and health.
- `main.tsx` applies the 5-minute stale time to those keys with
`setQueryDefaults`. No observer sets its own stale time for them.
- Not changed, and why:
- `auth/get-session` and `health` keep focus refetch and reconnect
handling for sign-out and reconnect detection.
- `cli-auth/me` (board access) keeps the reconcile because it detects
revoked access.
- The company list keeps the reconcile because live events invalidate
it.
- Company data (agents, chats, projects, approvals, labels, join
requests, live runs and others) keeps the reconcile. The socket is
closed while hidden, so the reconcile is how missed events arrive.
Keeping the socket open while hidden is a larger change and is not in
this pull request.
- Tests: new `live-reconcile.test.ts` covers the scope and the
stale-time defaults. The hidden-tab test in
`LiveUpdatesProvider.hook.test.tsx` expects the predicate.

## Verification

- `ui`: `npx vitest run src/lib/live-reconcile.test.ts
src/context/LiveUpdatesProvider src/lib/query-client.test.ts
src/lib/persisted-query-cache.test.ts` passes (283 tests).
- `pnpm verify` asks for broader CI coverage because `main.tsx` is
outside the resolved test graphs. Required CI provides it.
- Manual, on a local instance with the Mine page: hide the tab for 45 s,
then show it, and count `/api/` resource entries. `master` sends 27
requests and this branch sends 23. The four reads above are absent;
every company read is still present.

## Risks

- The reconcile was also how other tabs picked up changes to these
reads. A change made in another tab or browser now reaches this tab on
its next focus after 5 minutes, or on reload; before, it was the next
focus after 30 s. This covers an administrator changing an instance or
experimental setting or installing a plugin, and the same person
changing their workspace or sidebar preferences in another tab (for
example the coordinator or classic shell, or sidebar order). Changes
made in the same tab still apply at once.
- Low risk otherwise. Only the reconcile predicate and the stale time
change.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, via Claude Code with
tool use (shell, file edits, browser). 1M-token context window. Extended
thinking was off.

@paperclipai/ui

Published static assets for the Paperclip board UI.

What gets published

The npm package contains the production build under dist/. It does not ship the UI source tree or workspace-only dependencies.

Storybook

Storybook config, stories, and fixtures live under ui/storybook/.

pnpm --filter @paperclipai/ui storybook
pnpm --filter @paperclipai/ui build-storybook

Typical use

Install the package, then serve or copy the built files from node_modules/@paperclipai/ui/dist.

Editor dependency identity

Keep the root and workspace overrides for @codemirror/state, @codemirror/view, and @lezer/common aligned. CodeMirror requires shared extension identity, while Lezer parsers and syntax highlighters require shared NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with tags is not iterable. src/lib/codemirror-single-instance.test.ts checks the installed dependency graph and highlights sample code through the editor's real language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
