Multi-account-in-one-browser (esp. with per-tab accounts) leaked one account's client state
into another via shared localStorage keys. Scope every account-specific key by the tab's active
account (accountKey/readAccount/writeAccount/useAccountPersistedState helpers), so nothing bleeds
across accounts or tabs:
- Real leaks: selected playlist, client notification history + settings, onboarding-dismissed.
- UI position: feed page, channel-manager filter/view + tables, playlist sort, Settings/Stats/
Users/Config tabs.
- Previously DB-adopted caches (theme, hints, performance mode, sidebar layout, nav/filter
collapse) — now the cache is per-account too, so there's no flash of the other account's value
on login.
Kept intentionally global: siftlode.lang (needed pre-login on the Welcome page; the DB pref still
scopes it per-account after sign-in) and siftlode.seenVersion (a per-browser 'new version' banner).
E2EE private keys (IndexedDB) and the chat-dock key were already per-user.
components/ui/form.tsx replaces the per-panel copies:
- Switch — was duplicated in SettingsPanel (Switch) + ConfigPanel (Toggle) +
Sidebar (inline labeled toggle).
- Section (with a card variant) — was in SettingsPanel + Stats (plain) and
AdminUsers (glass card).
- SettingRow + HintLabel — the label+hint+control row was identical in SettingsPanel + Stats.
No visual change intended (Sidebar's toggle gains the standard knob shadow).
- errorDialog + hints now use createStore (drop their bespoke listener arrays).
- theme/sidebarLayout/notifications/App filters/Playlists plSort use readMerged/
readJSON/writeJSON instead of inline try/JSON.parse/catch.
- Stats, SettingsPanel and App's channel filter/view tabs use usePersistedState
(the 3 sites that reinvented usePersistedTab inline).
- Every siftlode.* key now sourced from the LS registry (no scattered literals).
The Settings > Sync tab moves into the Stats module: Stats is now a per-user
page (Overview tab = sync status + your own API usage + manual actions) with the
admin instance-wide quota dashboard + background-sync pause as an admin-only
System tab. The Stats nav item is visible to all users (was admin-only); the
Settings Sync tab is removed. Sync i18n strings move from settings.sync.* to
stats.sync.* (EN/HU/DE).
Each day now has a full-height track behind a solid accent fill, so low-usage
days no longer render as a near-invisible sliver that only stood out on hover.
Feed, VideoCard, Sidebar, PlayerModal, Channels, Stats, SettingsPanel,
OnboardingWizard, NotificationCenter, Toaster, ErrorBoundary and the relativeTime
helper are now fully translated in Hungarian, English and German, each with its own
locale area file (auto-loaded). Key parity verified across all three languages.
Track who burned how much YouTube API quota. A QuotaEvent audit log (migration
0009) records every spend with the triggering user (NULL = background/system) and
an action label, set via a request/job-scoped contextvar (quota.attribute) so no
call signatures change. User-initiated work (sync subscriptions, unsubscribe,
opt-in recent backfill, manual enrich) attributes to the user; scheduler work to
System, split by action.
- backend: QuotaEvent model + migration 0009; quota.attribute() contextvar;
record_usage logs events; entry points wrapped (routes/sync, routes/channels,
scheduler); GET /api/quota/my-usage + GET /api/quota/admin
- frontend: admin-only Stats page (header nav, page=stats) with daily bars +
per-user breakdown by action and range picker; 'Your API usage' in Settings ->
Sync for every user
Verified: attribution + endpoints compute correctly; events are per-user vs System.
