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).

Eweka takes ~1.5–2 s per XOVER command whatever its size. One connection
on recent a.b.boneless: 9–15k lines/s in chunks of 25k, ~20k in 50k,
~30k in 100k–200k. Four connections at once: 15k each at 50k, 22k each
at 100k (the same as one connection alone at that moment): connections
don't slow each other. CHUNK_ARTICLES defaults to 100k; edge:node posts a
batch every --batch-articles (500k) instead of every N chunks.

XoverClient joined all received pieces into one buffer on every arrival
(quadratic for a 2.6 MB reply), and turned the inflated check into text
the raw path doesn't use. The coordinator under load (3 workers, 4
connections): busy 40% → 13% of a core, Buffer.concat gone from the
profile. (master's relay uses the same client.)

On the 4-core workstation (shared with coordinator, web server and
database): 3 processes indexed 6 boneless ranges (12M headers) in 37 s,
~324k headers/s.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
End to end (workstation, recent a.b.boneless ranges from the spool): a 2M
range in 10–12 s, 166k–202k headers/s per worker process (edge:bench on
one core: 215k).
- Prefetcher: spooled_at was set against a total counted from the range's
resume point, which shrinks as the worker advances: the last chunks were
never fetched and the worker waited. Now counted against the whole
range, only new chunks counted, and leased ranges are always checked
against the files. Planned ranges ahead are bounded (it had spooled ever
more); the spool size is measured every 30 s (a stat per file).
- The stream sends an empty frame every 20 s while waiting for a chunk
(Node's fetch gave up on a quiet body after 5 minutes).
- A range taken over midway: the first batch starts at the resume point
(it started at the range's start and was refused).
- edge:node inflates the next chunk on the thread pool while indexing the
current one, and doesn't wait for a post before indexing on (posts stay
in order; a failed post stops the range).

edge:bench (one core): boneless 193k → 215k headers/s, ath 303k → 343k.
Same results on 800k real lines.

The worker reads the XOVER reply's text directly: fields by position, the
owner from the Xref without arrays (crossposts leave before any subject
parsing), a subject parsed once per file (cached without its segment
counter), a file's details as one shared object, dates as numbers.
Garbage collection had been ~22% of the time.
Same results as parseOverviews + segmentFromHeader on 800k real lines.
edge:bench (one core): boneless 137k → 193k headers/s (CPU 21 → 12.8 s),
ath (2013) 143k → 303k; peak RSS 1.15 / 0.87 GB.

The file key and release identity (two SHA-1 hashes and the release rules)

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.

Overview chunks in, per batch out: releases as encoded chunks, probe
candidates, counts per rule (crossposts per owner group, obfuscated,
garbage, per-article, incomplete), a sample of what was dropped, and
fragments near the range's edges.

lib/nntp (XOVER client, Xref, GROUP), lib/headers (subjects, file keys,
segments from overview lines; the yEnc path stays behind for phase 2),
lib/release (identity, random names, now in lib), lib/files (aggregator,
volume names), lib/rules (posting tools, owner by priority, release
verdicts), lib/chunks (release chunk codec). Their unit tests came along;
new ones for codec, rules and volumes.

The rebuild branch starts over (REBUILD.md): the API starter kit, with
Postgres instead of SQLite (its own database, DB_SEARCH_PATH for a
shared one in development) and the #lib alias. Phase 1's code is
imported from the current app module by module.

Every probe rewrote its file's row on the HDD (content_type, archive):
a new row version on a random page and an entry in each of the five
indexes. They now live in file_details on the NVMe; files rows are
inserted once. files:move-details copies the existing values after
the deploy; a later migration drops the old columns.

passwordFromSpot finds 30 more passwords in the stored descriptions (480
→ 510): words between keyword and separator, trailing "!!", the value on
the next line, "wachtwoord is x", "… wachtwoord. Deze is: x", "WW x" as a
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
importing files: details, the NZB password (over a spot-text one), the
spot-text password, placeholder NZBs. worker:spots does a batch when
idle; spot:postprocess works through the history (nzb_read_at).

Two probes of one release can be applied at once; when one deletes the
release as garbage, the other's inserts (e.g. a par2 listing) violated
the foreign key and the node got a 500.

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.

5.4M waiting inspection jobs took 3.3 GB of Redis and most of its single
thread. Producers now add file ids to inspection_queue; index-scheduler
feeds up to INSPECTION_FEED_MAX (50k) into BullMQ. inspection:from-redis
moves the existing backlog over once.

A sweep checked 430k noted releases in 51 minutes, nearly all without a
par2 listing or file total, where completeness can't change. Listed names
are now matched against the files themselves rather than through
binaries, which seeding mostly no longer creates.

Creating a partition deadlocked with file inserts 11 times in an hour, and
each failure ended the GC sweep before its deletes. The parent is now
locked first (lock_timeout 10 s), four partitions are kept ahead, and an
error is logged while the sweep goes on.

index-scheduler's loop ended when Postgres restarted (the active-groups
query was outside its try), leaving live indexing stopped for ~3 hours
while the process stayed up. Each step's error is now caught and retried
next round; worker:spots and worker:deferred wait 30 s and claim again.

Eweka answers 'no such article' after ~450 ms; a quarter of inspection
requests were for missing articles and each failed job was retried up
to three times. Files get content_type 'missing' instead; homelab also
records it from failure reports of nodes not rebuilt yet.

SeedService looked up every file of a batch across all files partitions

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.

Half the live leases go to higher-priority ranges, the rest to the others,
so a slow recent gap runs beside older history. With no article

Measured with 20 relay connections, plain and gzip both gave ~1.5 chunks/s

For 2026 a.b.ath articles Eweka's gzip replies have a long tail (p90 12.4 s

compression back on; plain replies are deflated for nodes asynchronously.

Dense recent a.b.ath ranges produced batches over the 64 MB body limit
(413). The node now posts such a batch in halves; only the second moves

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.

- seed:plan plans every part of a group's history no range covers (it
started below the lowest known range and left a.b.ath's 13 most recent
months out); seed_ranges.priority orders leases (seed:plan --priority).
- binaries.part_count, kept by the parts insert in the same statement:
claimCompleted compares it instead of counting parts every batch.
- file_keys: 64-bit hashes of all file keys; FileStore.insert asks it
before probing every files partition.
- worker:file stores 100 completed binaries per job with set-based queries.

matchPar2Releases checked every same-size release_files row's set and

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.

release_complete() matched each par2-listed file through a correlated
subquery that scanned all binaries per listed file, run twice per
inserted release_files row: one insert of a few thousand rows ran for
20+ minutes. It now reads the release's files once by release id, and
release_files refreshes once per INSERT statement.
seed:node's SEED_CONNECTIONS/--connections is now SEED_RANGES/--ranges.
