* db: request-path library functions use the request's connection
Library functions an API request reaches now take the request's Session (first argument) instead of
opening their own session or cursor, so a request needs one SQLite connection. Raw SQL runs through the
new `wrolpi.db.session_curs(session)`, a cursor on the Session's connection; `RequestDB.curs()` uses it.
- Search: files, videos, archives, flasher, and docs search share the request connection for the total,
the page of ids, and the page's models (3 connections -> 1).
- Zim search, including tag-filtered search and estimates (2 -> 1).
- Channel detail (`Channel.get_statistics` reads on the Channel's own Session) and the channel list.
- Video detail, edit, description, captions, comments and transcode. `get_video_for_app` and
`update_video` no longer commit; their handlers use `request.ctx.db.write()`, so editing a Video and
reading it back is one transaction.
- Tags (list, overlaps, recent), file statistics and estimates, other estimates, bulk tag preview, the
download list, retry, kill and the status summary, and docs/videos/archive statistics.
Not converted: file operations that refresh files inside the request (delete, rename, upload, channel
and collection tag/move) commit page by page in code shared with the file worker; the cached zim entry
lookup; config import.
The connection-count tests now assert one connection for every endpoint they cover (no xfails left), and
cover the videos and archive statistics endpoints, which had no API test.

* downloads: startup retries in a write session of its own
start_single_tasks still called retry_downloads() without a Session after it began requiring one, so any
start after a completed refresh raised TypeError there: incomplete downloads were not reset and the
download_on_startup enable after it never ran. Startup is not a request, so
DownloadManager.retry_downloads_on_startup() opens and commits its own short write transaction.
Tested through the method, not start_single_tasks: importing main registers its startup listeners on the
shared app, and every later test in that worker then runs them.

COUNT(*) OVER() forced SQLite to visit every matching file_group
before LIMIT, which is a full table scan of the (large) file_group
table — ~22s cold on a Pi for videos ordered by download date.
Count separately and cache for 60s by filters so indexed orders can
stop after one page. Past-the-end pages now report the true total.
Videos/archives/docs pagers keep totalPages across page changes.
test_search_videos_does_not_block_event_loop asserted a wall-clock
threshold (echo < 0.4s), which fails on loaded CI machines from
scheduler noise alone. Replace the timing with ordering: the mocked
search parks its thread on an Event, the echo is sent only once the
handler is provably inside the query, and the test asserts the echo
completes while the query is still held open. Events are only waited
on off the event loop, so a regression fails the ordering assertion
instead of deadlocking.
Verified both directions: passes repeatedly against the real endpoint,
and fails when the endpoint is changed to run the search on the loop.

* Fix API stalls: non-blocking switch worker, threaded searches, indexed Videos page
Three response-time fixes found by benchmarking the read-only API endpoints
hot and cold on real libraries:
* `switch_worker` runs on the Sanic worker's event loop every 0.1s and called
the blocking `multiprocessing.Event.wait(timeout=1)`. With no switch pending
(the normal state) this froze the loop for a second at a time; about a third
of all requests, including trivial ones, took ~1,000 ms. It now polls
`is_set()` and returns immediately.
* The search handlers (videos, files, archives, docs, zims) and `/api/statistics`
ran synchronous SQLite queries on the event loop, so one slow search stalled
every other request on that worker. They now run via `asyncio.to_thread`.
* The unfiltered Videos page (`POST /api/videos/search` with only an order)
used `mimetype LIKE 'video/%' OR ...` plus `COUNT(*) OVER()`, which visits
every video's index entry before LIMIT applies: seconds cold on a large
library on a spinning disk, and ~10 s hot for a deep page. It now seeks each
exact mimetype on the (mimetype, effective_datetime) index for `limit + offset`
rows and merges them, with the total from a separate count cached for 60 s.
Results are identical to the generic query.
Also adds `scripts/api_perf.py` (times every read-only endpoint against a host,
optionally restarting the API over SSH for cold numbers) and
`scripts/api_perf_compare.py` (merges per-host results). Host profiles live in a
gitignored JSON file; an example is included.
Measured on an 8-core docker host with a 10 GB library: median hot request
1,007 ms -> 22 ms; Videos page 1 hot 287 -> 108 ms, page 50 1,345 -> 120 ms.

* Serve the video description from its own endpoint instead of Video.__json__
`Video.__json__` computed `description` as `c_text or get_video_description()`,
where the fallback opens and parses the video's info json from disk. The list
endpoints serialize every result with `__json__`, so any page containing videos
without an indexed description (common: many videos have none) read their info
json files on every request, cold, for a field the list never displays. The
description is not part of search either: search runs against the FTS copy of
`c_text`, so the fallback never fed the index.
Drop `description` from `__json__` and serve it from
`GET /api/videos/<id>/description`, like comments and captions. The endpoint
returns the indexed `c_text`, falling back to the info json only there, for a
row indexed before descriptions were stored. The player page fetches it through
`useVideoExtras` alongside the comments.
Tests assert the list and detail responses never touch the info json, and cover
the endpoint's indexed, fallback, and not-found cases.

* Address review: thread-local zim sessions, fast-path equivalence test, comments
* Zim search, single-zim search, and search estimates run libzim off the event
loop, each opening its own session inside the worker thread rather than
passing the request's SQLAlchemy Session across threads.
* The Videos fast-path test now runs the same requests through the generic
query and asserts identical rows and paging for both date orders. The one
intentional difference is documented: past the end, the fast path still
reports the true total.
* switch_worker returns before its try block so the empty path does not clear
the event; its comment states the invariant only. The copied "synchronous
SQLite" comments are reduced to one line in one place.

Cold archive/video browsing took 18-90 seconds on a Pi: file_group rows
carry their indexed texts inline (SQLite has no out-of-line TOAST like
Postgres), so any plan that reads file_group rows to filter or sort
drags gigabytes of text pages through USB.
- Browse archives with file_group as the outer table (CROSS JOIN) so
SQLite walks the date index and probes archive's covering index;
driving from archive probed every file_group row for the sort key.
- Tie-break orders with fg.id instead of LOWER(fg.primary_path); the
rowid is present in every index, the path expression forced full-row
reads (and a full scan on the videos browse).
- Add a (mimetype, effective_datetime) covering index so the videos
mimetype filter + date order resolve index-only.
- PRAGMA optimize after a global refresh; the planner had no
sqlite_stat1 at all after the rebuild.
Warm timings on 10.0.0.9 (124k archives / 24k videos): archive browse
0.4s -> 0.22s index-only, videos browse 0.38s -> 0.07s; cold I/O drops
from ~124k random fat-page probes to a few MB of contiguous index.

The database now lives at <media>/config/wrolpi.db so a library (files,
configs, AND database) travels with the drive between WROLPi systems.
Core:
- wrolpi/db.py: lazy SQLite engine factory (WAL, busy_timeout=30s,
foreign_keys=ON); get_db_curs yields a plain sqlite3.Cursor; native
sqlite3 paramstyle everywhere (no compatibility shims); global sqlite3
adapters keep raw-SQL datetime formats identical to the ORM's.
- wrolpi/fts.py: FTS5 external-content search replacing tsvector/GIN.
Injection-proof websearch->FTS5 translator, bm25(10,4,2,1) reproducing
A/B/C/D weighting, fast(abc)/deep column filtering, snippet headlines.
Stemming contract pinned by dedicated tests (watch/watches/watched/
watching are interchangeable).
- wrolpi/schema_ddl.py: SQLite triggers shared verbatim by the alembic
baseline and test DBs; fixes the channel video_count DELETE/UPDATE
bugs and a latent total_size bug (it used the video id as channel id).
- wrolpi/db_bootstrap.py: startup auto-create/migrate; refuses databases
written by a newer WROLPi (db_version_mismatch); SQLite 3.40 floor;
network-filesystem refusal; never creates/migrates/trusts a database
beneath an unmounted production media directory (shadow-DB guard).
- Alembic: 85 Postgres-era migrations squashed into one baseline;
revision ids are dates (2026_07_10_1350) so filenames self-sort and
alembic_version says when a schema was created; render_as_batch=True.
- All raw Postgres SQL rewritten (ANY->json_each IN, array_agg @> ->
HAVING COUNT(DISTINCT), unnest->executemany/UPDATE..FROM,
generate_series histograms->strftime GROUP BY, DISTINCT ON->
row_number(), writable CTEs->two statements, jsonb_*->json_*, explicit
NULLS FIRST/LAST, LIMIT-before-OFFSET). Simple statements converted
to SQLAlchemy instead (flag upsert, download retry/summary/tag checks,
channel-by-tag estimate, Directory delete).
- Config imports count skipped entries; background dumps are blocked
after a lossy import so partial imports can never overwrite YAML
configs (they are the sole source of truth for rebuilds now).
- Search tolerates explicit JSON nulls for limit/offset (Postgres
treated OFFSET NULL as 0; SQLite errors).
- file_group.id/doc_section.id render as INTEGER PRIMARY KEY on SQLite
(BIGINT is not a rowid alias; FTS5 content_rowid requires it).
Ops teardown: docker-compose db service, CI postgres sidecars,
initialize_api_db.sh, controller postgresql service, psycopg2-binary all
removed. upgrade.sh stops/disables postgresql (data is NOT deleted;
`systemctl enable --now postgresql` restores it); systemd units no
longer Want postgresql.service.
Existing-user upgrade: first boot creates+migrates the DB, configs
import (tags recreate their FileGroups from disk), a refresh rebuilds
the library index. QA'd on the 10.0.0.8 RPi: rebuild matched the
Postgres baseline exactly; survived an uncontrolled hard reboot with
clean integrity checks.
Accepted behavior changes: FTS5 has no stopwords; bm25 length
normalization shifts some rank orders; fast-path d_headline is
un-highlighted; all-negative queries match nothing.
Deferred: Debian/trixie package lists (incl. sqlite3 CLI), Cypress
re-baseline, VACUUM INTO snapshots, exFAT/NTFS warning, auto-kicked
rebuild refresh with progress UX.

The file_group.textsearch tsvector indexes all four text columns;
d_text (captions, document text, zip contents) is ~90% of the data,
making ts_rank searches take seconds on large libraries. Add a
textsearch_abc generated column (title/author/description only, ~8x
smaller) and default all searches to it, with deep=true opting into the
full column.
Database:
- Migration adds the generated column and a GIN index (rewrites the
table; a few minutes on large libraries).
Backend:
- FilesSearchRequest, VideoSearchRequest, ArchiveSearchRequest, and
DocSearchRequest accept `deep`; each search function picks the column.
- /api/search_file_estimates returns both counts in one index-bound
query (COUNT FILTER on the abc subset): `file_groups` (fast) and
`file_groups_deep`.
UI (one coherent story across the count surfaces):
- The typing dropdown always suggests the deep count (what is findable).
- The tab badge shows the active mode's count so it matches the result
list.
- The gap is reconciled by a hint offering deep search: count-aware on
the global search ("No results in fast search. N results available in
deep search." / "N more results available..."), generic on the module
pages (no deep estimate there). The hint resets pagination.
- "Search Depth" toggle in the search filter modals, persisted as
?deep=true.
Tests that relied on d_text matches now pass deep=True, with fast-mode
assertions alongside. Also skip flaky test_download_channel on
CircleCI.

* Restore the censored-video search filter
Censored videos (no longer publicly available — detected when a channel
refresh drops them from the channel list, or when comment downloads fail
with "video unavailable/private/removed") are already flagged on
FileGroup.censored, but there was no way to find them since the search
rework dropped the old filter.
Add a "Censored" toggle to the reworked search filter modal, shown only on
the Videos page (showCensored). When enabled the video search returns only
videos with FileGroup.censored = TRUE, tracked via a ?censored=true query
param (useSearchCensored).
* Move Availability filter below the Tags/Results row

Python 3.11 is now required, old versions were causing unpredictability in tests. (Sanic does not yet
support 3.12)
Sanic has been upgraded to 23.6.0, which is the latest version that avoids this bug:
https://github.com/sanic-org/sanic/issues/2921
New strategy for multiprocessing is to create all multiprocessing tools in one process, then fork
to other processes. The previous strategy was to declare multiprocessing tools at the top of every
file, or wherever they were needed at import/creation. Now all multiprocessing tools are attached to the
app.shared_ctx. This means `api_app` is imported in many, many places.
This forced a change in how the DownloadManager works. Previously, it would continually run
download workers which would pull downloads from a multiprocessing.Queue. Now, a single worker checks
for new downloads and sends a Sanic signal.
Flags have been reworked to use the `api_app`. I removed the `which` flag functionality because the
`which` are called at import and needed their own multiprocessing.Event.
