Both are direct consequences of the round-1 F1 fix (uncaching
hasRestrictedPagesInWorkspace):
- F5: that EXISTS(SELECT 1 FROM page_access WHERE workspace_id=?) now runs
per-request on every whole-workspace list endpoint (global search + suggest,
favorites, notifications, recent, created-by), and page_access only had a
space_id index → a seq scan in the common zero-restriction case. Added
idx_page_access_workspace_id to the perf migration (up + down) so it's an
index-only existence probe.
- F6: the DomainMiddleware workspace cache invalidation was untested — the
int-spec passed `{}` for cacheManager, so bustWorkspaceCache's `del` threw into
its own try/catch and never ran. Added a Map-backed cache double with a working
del and two tests: updateSetting busts WORKSPACE_SELF_HOSTED; updateSharingSettings
busts WORKSPACE_SELF_HOSTED + WORKSPACE_BY_HOST(hostname). A missed/mismatched
bust key now fails the suite instead of letting a stale security-relevant
workspace row (enforceSso/status) outlive the mutation.
Gate: server tsc 0; workspace-repo-update-setting + page-permission-workspace-filter
int-specs pass on real Postgres (the new index applies via global-setup).
