Filters/sort/search/scope were written to the address bar on every change (a leftover
from sharing reproducible examples), giving two sources of truth. Make localStorage the
single source: drop the automatic syncUrl from setFilters/setPage. A "Share view" link
still hydrates filters on first load, after which the query is stripped from the URL
(stripUrlParams) so it stays clean. syncUrl is replaced by shareUrl (builds the link on
demand); the serializer now also round-trips scope.
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.
Backend: /api/channels (list + PATCH priority/hidden + attach/detach user tags),
user-tag CRUD on /api/tags, /api/sync/my-status (per-user channel sync counts).
Frontend: feed|channels page nav (URL-synced) from the account menu; a slide-in
tabbed Settings panel (Appearance, Notifications=6b sound+duration, Sync status +
actions + admin pause/resume, Account); a channel manager with priority, hide,
per-channel user tags, sync badges and 'view in feed'. Notifications now honor the
configurable sound + auto-dismiss settings.
Serialize the active filters to a compact, readable query string (only non-default
values) and parse them back on load, with URL taking precedence over localStorage.
Uses history.replaceState so it never spams browser history. A pasted link now
reproduces the exact view.
