The F1 integration test mocks the open-set as {} so openIds is always empty — every
node hits the collapsed branch, and the open-keep + recursion path (keep an OPEN
branch's children, recurse to prune a nested collapsed child) runs in zero tests. Add
a unit test: open parent (kept with children) → nested collapsed child (pruned to []),
plus a top-level collapsed node (pruned), with hasChildren preserved and immutability
asserted. Non-vacuous: clearing an open branch fails (a); removing recursion fails (b).

F1 (MEDIUM regression): a collapsed-but-cached branch showed STALE children on
re-expand after reload (the cache keeps children of any ever-expanded branch;
refreshOpenBranches only refreshes OPEN branches, but the fetch guard skips a branch
that has cached children). New pruneCollapsedChildren(tree, openIds) resets children
to [] (keeps hasChildren) for every node NOT in the persisted open-set, recursing
into open nodes — a once-per-mount boot effect. A pruned collapsed branch is then the
'unloaded' shape handleToggle re-fetches, so its first expand reconciles fresh (as
pre-cache). Open branches keep their children (refreshOpenBranches handles them, no
double fetch). Test: a collapsed cached branch with a stale child fetches fresh on
first expand after boot.
F2: gate the >4MB size-guard console.warn behind the writeFailureWarned once-flag
(like the quota branch) so editing a huge tree no longer re-warns every ~500ms; test
that an oversized tree is not persisted + warns exactly once.
F3: narrow the use-auth privacy comment (only tree caches are swept; other
localStorage entries remain).

On page reload the sidebar tree rendered nothing until every root page
was fetched (paginated), and children of expanded branches arrived even
later (breadcrumbs effect / socket connect) — the tree visibly jumped a
couple of seconds after load.
- treeDataAtom is now a facade over atomFamily(atomWithStorage) keyed
treeData:v1:{workspaceId}:{userId} with getOnInit: true — the cached
tree hydrates synchronously and paints on the very first render,
together with the already-persisted open-branches map. Public atom
interface unchanged (value or functional updater), all call sites
untouched.
- Custom sync storage: debounced writes (500ms, coalesced, size guard,
beforeunload flush), defensive reads (corrupted JSON -> []), no
cross-tab subscribe (localStorage is a boot cache only).
- SpaceTree renders on cached data immediately; "No pages yet" still
waits for the server. Once server roots merge, open loaded branches
are re-fetched fresh and reconciled once per space (shared
refreshOpenBranches, also used by the socket reconnect handler).
- Logout hygiene: clearPersistedTreeCaches() purges treeData:v1:* and
openTreeNodes:* by prefix and disables further persistence (kill
switch closes the websocket-write-vs-beforeunload-flush resurrection
race). Wired into both handleLogout and the 401 redirectToLogin path,
since cached trees contain page titles.
- Tests: tree-data-atom.test.ts (hydration, debounce round-trip,
corrupted JSON, scope isolation, logout purge, persistence kill
switch); expand-all suite adapted. 144 tree tests / full client suite
green, tsc clean.
