Saved "smart views" were feed-only; the Plex module is getting them too. Add a
`source` discriminator to saved_views ("feed" | "plex"), default "feed" so every
existing row and any source-less client stays feed. Widen the per-user unique
name constraint to (user_id, source, name) so a feed view and a Plex view can
share a name, and scope create's position numbering + the is_default "clear the
others" to (user, source).
Migration 0073 (ADD source NOT NULL server_default 'feed' + swap the unique
constraint; reversible). Endpoints: GET/POST take `source` (default feed).
Tests: source isolation, per-source default, per-source name uniqueness.
- saved_views: CreateViewIn / UpdateViewIn / ReorderViewsIn. PATCH presence via
model_fields_set; filters typed as dict (a non-object is now 422, an explicit
null on update stays a 400 "filters must be an object").
- feed: VideoStateIn(status) / VideoProgressIn(position_seconds,duration_seconds) —
the manual int()+400 in progress becomes a 422 on a non-number; the status
membership 400 and the video 404 are unchanged.
Gate: ruff clean.
Establish the R6 API-contract infra before the S1b payload:dict migration:
- iso(dt) in utils.py replaces the ~16 hand-rolled `x.isoformat() if x else None`
serializer idioms across the routes.
- get_or_404 / owned_or_404 in routes/_common.py — one 404 + existence-leak policy;
plex's _own_playlist_or_404 and saved_views' _own_view now delegate to it.
- require_write_scope dependency in auth.py collapses the inline has_write_scope→403
checks (channels subscribe/unsubscribe, playlists push/push-plan) that had drifted
into three different messages into one; the conditional delete_playlist guard stays
inline (its message was already canonical).
No response-shape change (iso == isoformat for a present value). Gate: ruff clean,
pytest 163 green (+ test_utils for iso).
Per-user named snapshots of the feed's FeedFilters. New saved_views table
(migration 0035, unique per user+name, position, is_default) + SavedView
model, and a /api/saved-views router (list/create/patch/delete/reorder)
gated behind require_human so the shared demo account can't pollute it.
Setting is_default clears the flag on the user's other views (one default).
