jsonb can't hold \u0000, and ON CONFLICT can't take a row twice in one

The coordinator (38) and the prober (8) had a fixed split; with history
paused the coordinator's stood idle while the prober's were its limit.
nntp_shares: each process syncs every 15 s (priority, minimum, what it could
use, what it has open) and gets what it may open: minimums first, then by
priority what each wants, growing only into connections the others closed
or gave up. The pool's size and the prober's lanes follow the grant; the
coordinator doubles its want while work waits for a connection, else asks
for its peak in use and a margin; the prober wants its maximum unless the
queue is dry. Claims scale with the lanes.

Over unreadable >= false Postgres walked every waiting entry of the kind:
2.5 minutes a claim at 28M archive candidates, the prober idle every other
minute. Per value each min and max is one end of the ready index (56 ms).

"Murdoch Mysteries S8D1 [00/80] - \"….nzb\"" beside its "[01/94]" upload
was a release of its own (23k sidecar-only releases on the corpus, 15k with
the poster's bigger release within 10 minutes). The settler queues small
settled releases (fold_candidates); the merger's third pass folds one whose
files are all sidecars into the poster's bigger release in the same group
within 10 minutes: the one sharing a 4+ letter word with its subject, else
the one under the same counter total, else none (via 'sidecar').

Voyager 1's second filter (D42) for voyager 2. Hourly, in order (the first
rule wins): dead (every probed first article gone), fake (a film, episode or
music name whose content is a program: archive entries all executables, or
the file itself by name or sniffed exe), repeated (the same first 16 KiB and
size in 20+ releases), locked (passworded, no password known), unusable
(random names, no inner name, no merge, no spot, a day after settling).
Verdicts in release_verdicts (rule, version) hide releases from search
(judged shows them); a verdict whose rule no longer matches is taken back.
Nothing dropped yet. Service judge; releases:judge --once --dry counts.

After reset 24 the catalog grew ~3.7 GB an hour (77 GB, root 31 GB free, 600k
history ranges to go). CATALOG_MAX_NVME_GB (as voyager 1's
BACKFILL_MAX_NVME_GB): once the default tablespace is over it, leases and the
prefetcher take priority < 0 only (the tail, the stored ranges); measured once
a minute. Off when unset; 90 on homelab.

A spot older than what the catalog has indexed (the spotter's first backfill
reaches back ~3 months) matched nothing and would have become a release of
its own, a duplicate once the history pass builds the upload. Unmatched
spots are matched again in turns (rematched_at) for 30 days; the 24 h before
a standalone release count from the inspection; a later match deletes the
spot's own release and links the header pass's.

Two processes, one NNTP connection each (the coordinator 40 -> 38):
- spots:read (service spotter): free.pt's overviews after the last article
seen, each spot's full header verified (lib/spotnet from voyager 1, as
Spotweb), its description, website and NZB articles; the password its
title or text names; delete/dispose messages applied.
- spots:inspect (service spot-inspector): each spot's compressed NZB read,
its files listed (spot_files), each matched to the header pass's release
by the same release identity in one of its groups within 48 h
(release_spots); unmatched spots matched again hourly, after 24 h a
release of their own (source spot) with the spot's NZB.
- release_passwords: per release and password, its source (nzb, spot-title,
spot-text) and spot; the catalog keeps only passworded.

hep, hephaestus and gyges post each file under a subject name of its own
(31,000 one-file releases), but the yEnc name in each file's first article
keeps the upload's random stem ("bX147zx8I0oEgj7nzFCiorCT0ps2jEcb.7z.001"),
one stem per counter total. The merger's second pass joins releases whose
lone inspections share a random stem: one group and poster, the same total,
within 48 h, no more files than the total plus 10. An expression index over
the stem; release_merges records the kind (via) and takes a stem.

Every kantodoNNN.bin test upload carries the same par2 set: 64 releases held
it nearby and became one release of 631 files for a set of 10. A set held by
more than 4 releases nearby isn't merged, nor members with more than 3x the
set's files plus 10.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A par2 index and its repost both hold a set: moving both rows to the target
broke par2_sets' primary key, and the round failed on it every minute from
20:28 UTC (no merges at all). Duplicates among the others go first; a set that
fails is logged and the round goes on.

The settler marks a settled release's candidates ready (and unreadable when
it had no readable name). Claims took the candidates by joining releases
from random points of the queue; in its newer half nothing had settled, so
a slice scanned to the end (0.3 s each, 20 slices and 5 tiers a claim) and
the prober stood still: 2.4M waiting, 0 probed a minute. Now an index over
the claimable rows only, the slices drawn within them.

131 uploads of 1 GiB test files ("kantodoNNN.bin", a.b.test) share their
first 16 KiB and size, so all matched one set's single file and became one
release of 1,284 files. A par2 file that matches more than one release in
the anchor's group and time window is left out; a plain repost of the same
file stays apart too.

A release whose last post is 6 hours old gets nothing from the tail, only
fragments from neighbouring ranges: settled once unchanged for 30 minutes.
Waiting 6 hours after it was read held every history release back from
phase 2 after each reset; with the hourly sweeps' resets the prober (and so
the par2 merge) never had work.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The prober stores, per probed article that starts a file, the MD5 of its
first 16 KiB (file_hashes), and per par2 body the set's whole file list
(par2_files, par2_sets): FileDesc holds the same hash per file, whatever
the file was renamed to. releases:merge (the merger service, no NNTP)
merges every minute the releases of one group, posted within 48 hours of
a release holding the set's par2, whose files the set describes, into the
one with the most files: chunks, probe candidates, inspections, hashes and
counts move; the par2's shared name when none was readable; release_merges
keeps what went where. Obfuscated uploads whose files were each a release
of their own ("[9/20] - "14f5999a…"", hep: 13,232) become one.
Also: corpus_sweep.py counts the marked ranges without psql's command tag.

FTD posts one upload's files to different groups ("Knowsum-Loops_Are_My_
Religion-WEB-2026-FTD": par2 and part1 to a.b.music.misc, part2 to
a.b.sounds.music, each article in one group only; releases 81825221 and
81825412): the catalog matched a chunk only to releases of its own
group. A chunk without one there now joins a release of its key in
another group whose window is within 3 hours, when none of its file
names are in that release yet; a post of the same files to another group
(other message-ids, same names) stays a release of its own, or its NZB
would hold every file twice. Functional tests for both.

- Search matches a word in the name or the inner name (trigram index on
inner_name, partial, built concurrently); "Readable names" includes
releases with an inner name.
- unlocked=1 (chip "No password") leaves out passworded releases.
- Results carry passworded and innerName: a Password badge, the inner
name under the release name.
- The release view: Inside and Inspected facts, a passworded notice, and
Contents (per probed article its yEnc name, kind, type, encryption and
the names inside) from release_inspections.
- Newznab: the password attribute from the prober; an obfuscated release
with an inner name is included, titled by it (without its extension).

Writers lock their group only, so two groups' batches can number the
same identity key at once (a spam post crossposted to 67 groups:
duplicate key ...:65, HTTP 500, the batch retried). Releases are now
inserted with ON CONFLICT (release_key) DO NOTHING, and those skipped
take the next number (up to 20 tries).

Eweka sends some ranges' compressed XOVER truncated, the same bytes
every time, while the plain reply is whole (a.b.models 3317215-3367214:
1,675,600 bytes that don't inflate, twice; 50,000 lines plain;
tools/false_end.ts). Not a false end of reply. The worker's corrupt
report removed the chunk and the range was fetched again, with the same
bytes: one range was reported 540 times. (Before this morning's change
the inflate check waited for more data until the 10-minute timeout,
like voyager 1's 'chunk never answered' ranges.)
A reported chunk's start goes into ranges.plain_chunks; the prefetcher
fetches those over one connection without XFEATURE COMPRESS GZIP
(NntpPool.usePlain, opened on demand) and deflates them here. A plain
chunk reported again sets the range aside (status failed, error). The
capture (edge:bench --capture) fetches such a chunk plain too.

A poster re-uploading under the same name made one release of all
uploads: in a sample, 24% of releases with 2+ files had a file name more
than once (4.3% of files extra copies), 70% of those copies posted a day
or more apart; their NZBs listed each copy.
- File assembly keeps a re-upload's copy apart: a part already in every
open copy, posted more than 3 h from them, starts another copy; a
missing part fills the nearest copy (a re-send of what was missing),
a re-sent part near a copy that has it is ignored as before.
- A key's files in a batch split into uploads where posting pauses for
more than 3 h, counted from the latest article posted so far (a file
that takes hours to post doesn't split it); each upload is judged and
chunked on its own (ReleaseChunk.upload, .postedLast; candidates carry
their upload).
- The catalog matches a chunk to the release of its key whose articles
the range's group owns and whose posting window is within 3 h, else
starts one (key, key:2, …): releases get identity_key, group_id,
last_posted_at. Keys are locked in order (advisory locks), so
concurrent batches neither deadlock nor both start one; the merger
writes in key order too. The same upload multi-posted to other groups
is a release per group.
- The gap: 91% of uploads post within 3 h; 73% of re-uploaded copies
come later (releases:upload-gaps). releases:duplicates measures the
duplicate names.
Both implementations; check.ts compares the windows and uploads too
(identical on all captures; Rust tests mirror the TypeScript cases).

- releases.complete is computed with every batch (files >= the
counter's total) instead of only when a release settles after 6 quiet
hours: the 'complete' filter matched nothing in a fresh catalog.
- A release's file total comes from any counter form (counterTotal:
'(01/10)', 'File 27 of 132', …), not only [i/M]; the post rule's key
keeps the [i/M] total, so keys are unchanged. Both implementations.
- groups.tail: a group's live tail can be paused (its history and owner
priority stay), e.g. to let other groups' history go first.
- Stats: history by articles, and the current pass (history ranges
before those deferred 2000 priorities behind) as its own figure; the
header showed 0.1% of ranges counting 145k deferred ones.

Files cut by a range's edge are put together once the ranges around them
are done (coordinator:run, every minute): a complete file is judged by the
rules and written as a release chunk with probe candidates; one still
missing parts while both neighbouring ranges are done is dropped and
counted (incomplete/edge). A neighbour not planned yet counts as not done,
except before the group's oldest article. BatchStore.writeReleases is the
shared write path.

Measured on two neighbouring boneless ranges (merging their fragments):
- 99.8% of fragment files were single articles of a random-named
'file' of >100 parts: a random subject per article, which never
completes from headers. They now count as per-article.
- A file is kept as a fragment when its first part seen is above 1 and
comes within the start window (the idle window: uploads in busy groups
spread over minutes, and a 50k-article edge zone is ~30 s of boneless),
or when it was still open at the range's end with later parts missing.
Anything else missing parts is incomplete and only counted.
Per range: 70,308 → 130 fragment files; merged, 47 of the 48 files met
complete (57,558 segments, ~8% of the range's kept segments).

End to end on the workstation (coordinator:run, the API, edge:node, real
NNTP): a.b.e-book.french and a.b.cd.image.playstation2.dvdiso ranges.
- Prefetcher: every connection takes the next missing chunk (leased
ranges first, in order); one connection per range (~26k lines/s) kept
the worker waiting
- executable rule: releases of bare executables (malware floods named
after films and software) are dropped; they were 92% of the catalog rows
of the test ranges, 21% of the segments
- fragments per file (details once) and gzipped batch bodies; the JSON
limit (1 MB by default) raised to 256 MB, empty strings kept (a rule
count's key is '')
- release_chunks.batch_from is a bigint (boneless article numbers)
- tests get their own database; edge:bench --store times BatchStore:
1.3 s for a boneless range (1.24 ms per release chunk)

- groups:add / ranges:plan / nodes:create / coordinator:run commands
- the node API: lease, the range's chunks as one framed stream from the
spool, batches, heartbeat, finish, release (node guard, token per node)
- edge:node: needs COORDINATOR_URL and NODE_TOKEN only (placeholders for
the rest), posts a batch every 10 chunks, gives its range back on SIGTERM
- releases are gathered per batch: 1.04 chunk rows per release at 10
chunks per batch (1.35 when built per XOVER chunk)
- partitions are checked per batch instead of remembered

A batch is stored in one transaction and only at its range's resume
point, so a retried batch can't count twice. Garbage is judged before
per-article: a dropped tool isn't worth reading bodies for either.

passwordFromSpot finds 30 more passwords in the stored descriptions (480

whole line.
Listed spots were read from their overview only, so the NZB's own
password and the description were unknown for 2.27M of them.
SpotService.readListing reads the spot's article and NZB without

spot-text password, placeholder NZBs. worker:spots does a batch when
idle; spot:postprocess works through the history (nzb_read_at).

Random-named uploads that never get a real name or password were ~90% of
what seeding stores. Two filters:
- before storing (seeding, ingest): random-named uploads of a dropped
signature (posting tool from the Message-ID, first group) or of a
release dropped after its probe aren't stored; 2% of a dropped
signature's releases are still kept and probed. Stored files of dropped
signatures aren't probed.
- after a probe: a random-named release that is still unnamed, without
password, names from files or spot, with all its probes done, and
encrypted, a container or missing its first article, is deleted and
tombstoned in dropped_releases.
Signatures are learned by gc:scheduler from a sample of probed releases
(signature_probes); garbage:learn --seed fills it from existing files.
