the store every dashboard layout is written through had no tests. writing them found
a live defect on its rollback: the guard asked "does the cache still hold what i wrote?"
by reference, and setQueryData runs react query's structural sharing, which rebuilds an
object rather than storing the one it was handed. verified against 5.101.4 — an object
comes back !==, a string comes back ===. so the check was false for every container the
store exists to hold: every layout, every config.agentName. a refused write kept its
optimistic value while the toast said it had been rolled back, and the change vanished at
the next reload. only primitives ever reverted, which is why it went unnoticed.
replaced with a per-key write sequence, which asks the question the identity check meant
to ask — has anything written this key since — and does not depend on identity at all.
14 tests: readValue's kind guard, the optimistic write and its updater composition, and
five on revert including the object regression pin.
also moves testing-library's cleanup into test-setup. it auto-registers afterEach at
module import time, so bun attaches it to whichever file imports the library first and
every later file silently gets none. adding this test file was enough to break fourteen
assertions in DataTable.test.tsx, which does not import it. preload has no file scope, so
registering there removes the ordering from the question.

Two second implementations, both removed rather than fixed.
DashboardPreview minted template panel ids with its own module-level counter,
tpl-1, tpl-2, no entropy, reset every page load. Two dashboards built from
templates in the same page load held panels with identical ids — and a panel id
is not decorative any more: agent_panels addresses an agent by
(dashboardId, panelId), and terminal-conn-<panelId> and file-viewer:<panelId>
key persisted state by it. The templates now call the core uid(), which is
exported from the Workspace barrel for the first time so there is one minter.
metasToRegistry is Object.fromEntries, so two apps sharing a key means one app
stops existing and every panel holding its appType renders the other. The todo
asked for a throw in dev; a throw takes down every dashboard at runtime for a
mistake made at edit time, so this is a test over the real meta list plus a
console.error. All 44 keys are unique, and the test now says so rather than the
doc.
Getting the real list into a test needed test-setup.ts to provide localStorage:
MusicPlayer/useLyricsOpen.ts reads it at import time, so the whole app graph was
unimportable from a test. That unblocks testing anything that pulls in a panel
app.
Also deletes officerdev/src/useAppRegistry.ts — a stub returning {} with a
different shape from the real hook, imported by nothing.
