SeedService looked up every file of a batch across all files partitions
after inserting it (15% of Postgres' active time); the merge job read
every release on each GC sweep.

Par2 naming needs the fingerprint inspection stores on a binary, and the
GC deleted seeded binaries (6 h unfingerprinted, 48 h stale) long before
the inspection queue reached them. binaries.awaiting_inspection protects
them for up to 7 days; the GC deletes use partial indexes so they don't
read past waiting rows. Seeding no longer creates binaries for files that
aren't inspected (~85% of a.b.ath), which only churned the table.

Copying all existing keys in the migration read the files rows from the
HDD for over half an hour and held up the deploy. gc:scheduler now copies
them in slices (FILE_KEYS_FILL_SECONDS per sweep) and FileStore checks
every partition until the fill is complete.

matchPar2Releases checked every same-size release_files row's set and
date (18 s per batch of body-derived binaries); now an index on
release_files (release_id, size) drops the repeated sizes first: 0.16 s.
File inserts updated their release in four row triggers; one statement
trigger now updates each release once per INSERT. Completeness is noted
in release_dirty and recomputed by gc:scheduler every 30 minutes.

Spotnet (CONCEPT D29):
- Index free.pt fully and import spots with their descriptions, categories
and NZBs; a spot renames its release, since Spotnet names are more
trustworthy than names derived from subjects.
- Find passwords in spot descriptions too, and tell "needs a password we
have" from "needs a password we don't have".
Content inspection:
- List the contents of 7z (.7z.001) archives, SFV sets, nicovideo uploads
and other archive-like files; mark yEncBin .bin containers as encrypted.
- Take real names from yEnc headers for randomly named files, and merge
uploads that were split across posts.
Storage (D31, D32):
- Store segment lists zstd-compressed behind the FileStore accessor.
- group:backfill indexes older headers at low priority and pauses when
the NVMe or HDD part of the database gets too large.
Grouping (D35, D36):
- Lone header segments wait in staged_segments until a second segment of
their file arrives, which drops the per-article junk binaries.
- Counter grouping joins random-subject uploads by poster, [i/M] counter,
part count and day.
Search and maintenance (D33, D34):
- A trigram-indexed search_text column, smaller indexes, estimated stats.
- Passes that clean up nonsense names; weekly index maintenance; GC budgets
per kind.
- Web UI: grey out stale results while a search runs and cancel superseded
requests. Count only up to 1,000 matches for the page, which made filter
clicks take seconds (Newznab keeps the 10,000 cap).
