GET /api/channels summed every subscribed channel's videos by reading each video's heap page
(681 MB on prod): 51-61 ms warm, but 2.25 s on a first open and 6.4 s under EXPLAIN once the
table had left memory. /feed/summary and /feed/years did the same (~140 ms warm, ~800 ms cold).
Migration 0095 replaces ix_videos_channel_pub_desc with the same key INCLUDING the columns
those queries read, so they are Index Only Scans over a 25 MB index. A test holds the queries
and the index's column list together.
The admin Configuration page did a db.get per setting (two for an unset one): it now reads
every override in one query (~40 ms of ~55 on prod).
- NavRailGroup: one "Admin" rail row opening a panel of the admin pages (links, so a
middle-click still opens a tab); the rail fits 133% zoom without a hidden scroll
- sysconfig.SECTIONS orders the config groups under four headings (every group in exactly
one, test-held); the page shows them as Settings' side list (Tabs `group` headings);
the lone registration group reads "Registration" under "Access"
- StatTiles / StatTile / StatBars: the Statistics overview's figures as tiles, the
per-operation quota use as horizontal bars (a zero draws none)
log_level, search_source, download_layout and the transcode hw/preset
were typed by hand, and every consumer carried its own guess at what a
typo meant. The value set is now a Literal in config.py: pydantic
rejects a bad env value at boot (any letter case accepted), sysconfig
refuses a bad override and derives the admin picker's options from the
same Literal, and the consumers read the value as-is.
The Configuration page renders a choice key as a segmented bar, or a
dropdown past six options, with translated option names. Its tabs now
follow the registry's order instead of a hand-kept copy that had
already dropped the explore group.
A single-choice FilterSelect now opens on the option in use: in the
browser it could land on the first row instead.
