A failed NNTP login gives the range back uncounted (no attempt used), and a
node with nothing to lease holds no connection. Replaces log-in-before-lease,
which kept idle connections and logged in again every minute while idle.

A seeding node that waited over two minutes for the seed API (restarting)
had its idle NNTP connection closed by its own timeout, and gave its range
back. Now the timeout runs only while a reply is awaited.

No new range while the database's NVMe part or the hdd tablespace is over
BACKFILL_MAX_NVME_GB / BACKFILL_MAX_HDD_GB; nodes ask again a minute later.
seed:status says when leasing is paused. The NVMe part was at 47 GB of 50
with a plan for all of a.b.ath queued.

- seed_nodes (hashed bearer tokens) and seed_ranges (planned ranges with
lease, resume point and counts); migration …140.
- SeedOrchestrator: lease (oldest plan first, FOR UPDATE SKIP LOCKED; a
lease without a batch for 15 min passes to the next node and resumes at
next_id), batch (stores files and fragments, moves next_id), finish,
release, plan (from below live indexing / the backfill / earlier plans
down to N days back; takes over the group's backfill), status.
- Seed API under /api/v1/seed (lease, ranges/:id/batches|done|release,
status) behind a node-token middleware; JSON bodies up to 64 MB after
gzip.
- seed:node runs a node: no database or Redis, outgoing HTTPS only, N
connections, gzip batches, retries for network errors and 5xx, drops a
range on 409, gives its ranges back on SIGTERM. seed-node/ has a compose
file that builds the image from this repository.
- seed:token, seed:plan, seed:status for the operator. Header parsing moved
to lib/ingest and the range loop to lib/seed/runner, shared by seed:range
and seed:node.

- lib/nntp/xover_client: a minimal one-connection client for seed:range
with XFEATURE COMPRESS GZIP (a zlib stream after "224 … [COMPRESS=GZIP]",
then a "." line; 420 for an empty range). About 6x less header traffic.
Overviews come out with the field names nntp-js uses.
- SfvService.claimAll: one sfv_entries lookup per stored batch.
- Fragments go through the regular ingest path beside fetching (at most
two batches in flight); a failure fails the run at the end.

A seeding node fetches a range over one NNTP connection, parses headers
with the live rules, groups them into files in memory (lib/aggregate) and
stores per complete file its release, the file and a completed binary
(SeedService), instead of one parts row per article. What doesn't complete
within the window goes through the regular ingest path as fragments.
`--dry-run` only fetches and aggregates, to measure a node.

The first version matched extensions in search_text, which was wrong and
slow: file names enter search_text as stems without extension (so plainly
posted .mkv files were missed), and matching the TOASTed text took 3-4 s
for common types.
- Migration …130: releases.extensions text[] (two to four characters with
a letter; .7z.001 and .r00 count as 7z and rar), kept current by triggers
on files (name, release) and on releases (archive listing), filled with
one sequential pass over files, with a GIN index.
- Search: ext matches with `extensions && ?`.

- API: min_size and max_size in MB, ext as a comma-separated list. An
extension matches as a whole word in search_text (file and entry names,
dots as spaces), so "iso" finds .iso files but not "ISOLATION", which a
plain search word matched as a substring. The trigram index serves it.
- Web UI: a size range and an extension field in the filter row, kept in
the URL like the other filters.

Of 5,000 waiting inspection jobs, 3,212 were queued only because their
stem looked random, and 2,044 of those were later RAR volumes
(xyz.part47.rar, .r00) or par2 recovery volumes (.vol03+04.par2). Their
first segment adds nothing: the set is listed from its first volume and
named from its index .par2, as for readable names already. Each one cost a
~700 KB download; inspection pulled ~85 MB/s and fell behind the backfill.
- isCandidate() rejects later volumes (isLaterVolume) before the random-
name rule.
- worker:file only queues files that are candidates, so the ~30% that
inspection skips anyway no longer take queue slots.

Crossposts, reposts and backfill ranges keep bringing articles of files
that worker:file already created. Ingest inserted their header parts again,
and GC's copied-parts pass (which searched all binaries for parts on every
batch) removed only 150k-450k per sweep: parts grew to 68M rows, 56M of
them belonging to finished files, and the 23 GB table paused the backfill.
- Ingest skips header parts (no per-part CRC) for binaries with a file_id.
- GC drops copied parts with a cursor over binaries, 2000 per statement.

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).
