default_timezone existed as a system setting (admin-editable, exposed
via SettingsRegistry.DefaultTimezone) but nothing read it at user
creation — the CreateUser query didn't even carry the column, so every
new user got the DB default UTC regardless. Both creation paths
(public register + admin create) now seed the user's timezone from the
setting, validated with time.LoadLocation and falling back to UTC when
unwired/empty/invalid.
Test-infra fixes surfaced by the run: TestUpdateProfileSelfEdit was
self-editing the SHARED admin (renaming it past the harness cleanup's
preserve-list, leaking a second admin row that broke the last-admin
tests) — it now edits a dedicated user with a unique name; the
last-admin tests get an ensureSingleAdmin precondition helper; the
websocket collection name is run-unique (non-test names persist in the
shared DB and UNIQUE(user_id,name) 409s on rerun).
The family-lens hardening: library_visibility was only enforced where
file bytes flowed (download/reader/OPDS) — metadata surfaces leaked
hidden libraries to any authenticated account, and registration was
open by default with no admin-side user creation.
- Series are grouped PER LIBRARY now (same name in two libraries =
two entries: manga adaptations / LN splits no longer merge);
/api/series aggregates only the requester's VISIBLE libraries and
/api/series/books REQUIRES a visible library_id (breaking contract;
web + app clients updated in the same change).
- /api/media-items, item detail, and the reader content endpoints
(chapters/panels/outline/THUMBNAILS — page images leaked unguarded
next to a gated GetPage) all enforce the visible set; resolveLibrary
no longer honors a hand-typed library_id outside the visible set.
- Annotation/note/bookmark mutations (update/delete/tombstone, sync
LWW paths incl. conflict resolution) carry ownership predicates:
another account's bare row id is a 404, not a silent delete.
- Admin user creation: POST /api/auth/users (AdminMiddleware) + a
Create User card in the admin Users UI — accounts stay creatable
with self-service registration OFF, which is now the schema default
(fresh installs; the first-admin bootstrap exception is unchanged).
- Tests: series contract re-pinned (per-library, visibility 403s),
new ownership + admin-create integration suites, OPDS all=1 test
now passes an explicit page size (shared-DB growth made the fresh
books fall off page 1), device-cap helper switched to the admin
endpoint.
