User: Rust is the product (option a). tools/edge-bench-rs moves to edge/
(crate edge; binaries edge-node, the worker, and edge-bench, the replay).
CI's new job edge runs cargo test and edge/check-fixtures.sh: both
RangeIndexers on three committed captures (edge/fixtures, 25k overview
lines each of a.b.models, a.b.ath and a.b.boneless in 5 chunks, 3.5 MB),
compared field by field with check.ts; deploy waits for it. The
TypeScript RangeIndexer stays as check.ts's reference. README: what it
is now; the benchmark findings as history.
Random names: looksRandom missed long tokens of capitals and digits
("51294P1CUKR2R35X", release 74539068, readable and a Newznab title).
12+ capitals and digits switching 6+ times between them are random
(COD4MW2REMASTERED switches 4 times, BEATLES1964REMASTER twice); both
implementations, identical on the fixtures.

Lone candidates are often par2 volumes of random-named sets
("42507096….vol007+08.par2"): their yEnc name was taken as the inner
name. Packaging names are skipped for lone files too, and a name that
starts with the release's own name says nothing new.

A release can have several candidates of a kind (two RAR sets): keyed by
(release, kind) both landed in one upsert ("ON CONFLICT DO UPDATE
command cannot affect row a second time"), and the batch was lost.
release_inspections is keyed by candidate now; the first run's results
are cleared and probed again. A random-named file's yEnc name is often
its random name: an inner name equal to the release's name is dropped.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
probe:run (compose service prober, PROBE_CONNECTIONS, default 6) claims
waiting candidates of settled releases (lone, then par2, then archive),
fetches each article with BODY over connections of its own (no
compression) and inspects it: the yEnc name and size, the content type
from the first bytes, a par2 set's files, a RAR volume's entries and
whether they're encrypted. Results per release and kind in
release_inspections (CHUNK_TABLESPACE, the HDD); on the release
passworded, inner_name (the largest content name) and inspected_at.
430 = missing, not yEnc = error, both final; connection trouble puts
the candidate back.
Fetch and parse in one process: an article takes ~0.1 s per connection,
parsing a few ms (no queue in between). Parsers from voyager 1 (lib/yenc,
lib/rar, lib/par2, lib/content sniff) with their tests; XoverClient.body;
yencode.

A file name with a NUL ("…Brutal Erpresst.ra\u0000…") failed every
batch of range 155595 (HTTP 500, jsonb: \u0000 cannot be converted to
text), so the range looped. fromWire drops NUL from every string.
The chunk deadline was given up 258 times in 3 hours at 300 s (~1.4 a
minute, each holding a connection for 5 minutes): 180 s.

A worker waited on one chunk of a leased range for an hour (range
146477: five 15-minute stream timeouts, then the range took 63 s; 88
"stream: Peer disconnected" overnight). The silence timeout doesn't
catch a reply that trickles: a chunk still coming in after
NNTP_CHUNK_DEADLINE_SECONDS (300) is given up, its connection closed,
and fetched again. The report names the oldest request in flight (range,
chunk, age, bytes in) and counts deadlines.
Batches failed with "Maximum call stack size exceeded" (8 overnight):
Math.min(...segments) on a fragment with more segments than the stack
takes arguments.

Once a second: pool connections with a command in flight, loops
fetching/writing/idle; per request GROUP time, XOVER time to the status
line and the transfer, transfers with a silence over 5 s. The old
"connections busy" (fetch time of the chunks finished in the minute)
said 59-75% while all 40 connections were in flight all the time:
dropped.
Homelab: 39-40 of 40 in flight, no idle loops; the status line comes at
once, the whole 8-35 s is the transfer, with data flowing (few gaps
over 5 s): ~3 MB per chunk at 0.1-0.4 MB/s per connection.

A chunk not in after NNTP_HEDGE_AFTER_SECONDS (10) is asked again on one
of NNTP_HEDGE_CONNECTIONS spare connections; the first answer wins and
the other connection is closed (lib/nntp/hedge.ts, tested). Connections
can be retired after NNTP_CONNECTION_MAX_MINUTES (±25%). The prefetch
report counts hedges and slow first requests by connection age.
Homelab, 15 min each: hedging on (40 + 6) 280k articles/s, off 273k.
The second request won about half of its races, but ~25-35% of first
requests were slow (>10 s) at every connection age, so neither helps:
Eweka is slow under our load, not on particular connections. Both
off by default; the age statistics stay.

A picture group's 500k articles made batches over the server's 256 MB
body limit: HTTP 413, the range given back and leased again in a loop
(148597: 39 times in 30 minutes). The worker now also posts once
100,000 completed or edge-cut files wait (RangeIndexer.pending).
A stats refresh that failed kept the previous totals silently; it

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.

So a cover 'x.jpg' joins 'x.part01.rar' in a stem-named post; an image
set like 'IMG_008' keys as the stem 'IMG'. Both implementations.

Picture groups made a release per image: 501k single-file releases in
the first 24 ranges of the bottom 500 groups (a.b.models 385k), ~120M
for all of them. Counters written out ('File 027 of 132', '[12of42]',
'104 of 472', '[2239-6389]', '02/17', '0097-1574'; only when the first
number is at most the second, so '[1948-12]' stays) and per-file sizes
('76.88 MB', '335555 Bytes') kept every subject unique.
- subjectRemainder removes those counters and sizes, and empty brackets.
- A subject-named release is bounded by its counter's total
(counterTotal: the first form found): uploads a poster names alike
stay apart, an upload's files (par2, nfo) together.
- Images and audio tracks don't take the poster-tag rule: the subject
names the set or album. An image set without a counter: the image's
name up to its last number, without numbers.
- Documents and comics (pdf, epub, mobi, azw3, djvu, cbr, cbz, cb7, chm,
lit, doc, docx) are a release each: collections post hundreds under
one subject ('cw-horror&mystery').
releases:regroup --group re-keys a group's indexed releases together:

audiobooks 4,106 -> 1,724, playstation 3,309 -> 2,345; comics and
e-books a release per item; boneless unchanged. Ported to edge-bench-rs;

Release 145637 held four albums: the poster puts '[KiLL.dA.FuCkIn.
EaStErRaBbIt]----' before every upload, and the text outside the quotes
(when it names a release) was the key with the poster. The same made
one release of a poster's albums under '(PowBeertje80 Posted)' (a post
id, with the same [i/M]), of masterposts' films, and of one volume of
every set in a DVD9 post.
Now, when the file's stem describes something itself (12+ letters and
digits, two words of 3+ letters) and the text outside the quotes shares
no word with it (4+ letters as part of the stem, 3-letter words and
numbers whole; boilerplate like www/net/posted not counted; no 5+ digit
per-post id), that text is taken for the poster's tag and the stem
says which release the file is. Albums of track files ('FTA … Ketchup'),
'DIE_ZEIT_35' with '35_China_dl', 'FTD769997' posts, scene names with
abbreviated file names ('grp-sm') and generic sidecars ('file_id.diz')
keep their grouping.
releases:regroup re-keys a sample of the catalog with the current rule:
on homelab's test data 145637 → 4 albums, 111566 → 17 albums of 27
files, the rest of the subject releases that change mostly lose an ad
image ('Flyer-download-2-Day.gif'); stem releases unchanged. Ported to
edge-bench-rs: check.ts still finds all captures identical (ath 2013:
16 → 76 releases on both sides).

coordinator:run plans the articles after each group's last range every
TAIL_EVERY_SECONDS (120): one LIST ACTIVE per name prefix gives every
group's newest article, and new articles become ranges at priority -1,
leased and prefetched before any history. A group gets a tail range once
it has TAIL_MIN_ARTICLES (100k, a chunk) new or its last planning is
TAIL_MAX_DELAY_MINUTES (15) ago, so quiet groups don't make a range every
round. History (planAll, hourly) is now only for groups not planned yet.
ranges:plan --tail plans one round.
Found on the way: with XFEATURE COMPRESS GZIP on, Eweka compresses LIST
ACTIVE's reply too ("215 NewsGroups Follow [COMPRESS=GZIP]"), and
listActive waited for a plain end that never came (groups:add --top too).

For workers on a shared line (poweredge-kantoor: 160 Mbit/s): the range
stream is read at most at the cap, TCP holds the coordinator back. The
cap is the node's, split over its processes (also EDGE_MAX_MBIT).
REBUILD.md: where workers run (connections set the speed; remote workers
take CPU off homelab).

On homelab (1 Gbit, 20 connections, ~630k articles/s) the coordinator
used 1.3-1.7 cores, mostly GC of the text it inflated only to know a
compressed reply was complete, plus a copy of every reply. A raw reply
is now complete when it ends in ".\r\n" (no copy): 0.4-0.5 cores at
the same rate.
".\r\n" can also end a network read inside the compressed data (~1 in
16M reads, a few dozen times over the whole target). Such a chunk
doesn't inflate on the worker: it reports it (POST ranges/:id/corrupt),
the spooled chunk is removed and the range goes back to the queue; the
prefetcher fetches it again. The rest of that reply breaks the
connection's next command, so the connection is replaced.

It waited for every chunk in flight, and a connection the server held
back (after killed coordinators left sessions open) waits up to the
10-minute reply timeout: it never seemed to stop. It now waits at most
15 s, then closes all connections, busy ones too; the greeting and login
time out after 30 s. And run() ends with terminate(), as edge:node does.

The coordinator logs a line a minute: chunks fetched, articles/s,
seconds a chunk, how busy its connections were. It showed the
workstation's runs are bound by its 100 Mbit line now (10 connections
99% busy, ~89 Mbit/s: compressed XOVER is ~69 B an article on recent
boneless), not by the code.
The check that a compressed reply is complete (inflating it) ran on the
coordinator's event loop, ~60 ms a chunk; now on a thread-pool thread.

A lease was only granted for a range with spooled chunks, and the
prefetcher kept ranges ahead per active lease: once the spool ran dry a
worker got none and slept 30 s, fewer ranges were leased, fewer
prefetched. Three workers held one lease between them (~50k headers/s).
A lease now takes a spooled range first, else the next planned one
(leased ranges are fetched first; the stream waits).

decodeFrames joined each network piece (~64 KB) onto the frame so far:
a chunk of MBs copied over and over, 5.4% of a worker's time in an
end-to-end profile (the bench reads files, so it never showed). Pieces
are now joined once a frame is complete. A batch post's gzip (1.6%) runs
on a thread-pool thread.

A slice of a chunk's text keeps the whole text alive (tens of MB) for as

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 (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).

Listed spots were read from their overview only, so the NZB's own

SpotService.readListing reads the spot's article and NZB without

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.

Inspection is split into prepare (database), probe (lib/content/probe:
downloads, decoding and parsing, no database) and apply (database).
worker:collection runs all three; seed:node with SEED_INSPECTORS leases
jobs from the same queues through the seed API (BullMQ manual leases),
fetches articles through the seed API and posts the probes back.
A node now needs only SEED_URL and SEED_TOKEN: the settings the app
requires but a node never uses get placeholders for seed:node.

85% of the 7z archives inspected have encrypted headers (-mhe). Their
encoded header lists the 7zAES coder, so the packed header stream is no
longer downloaded and bsdtar no longer runs for them.

Inspection lists only the entries whose headers are in the first segment
of a first volume. A walk hops from header to header, fetching one segment
per entry and volume, in its own queue (one job per collection worker) on
NNTP connections inspection isn't waiting for. content:walk-archives queues
releases inspected earlier (CONCEPT D40).

Five ranges "never answered" in 10 minutes, yet their chunk came back in
0.3 s on a fresh connection: the news server drops idle connections
without telling, and the pool's next request on one waited for the
10-minute inactivity timeout. Now: SEED_NNTP_TIMEOUT_MS 90 s (inactivity;
slow ranges keep streaming), one retry on a fresh connection, and pooled
connections idle over 60 s are replaced before use.

- A range reported to its end but not finished (its node went away at
the very end) was leased again with start past end; nodes asked for
"from 49208000000 to 49207999999", got 400, and the range failed after
five leases. The orchestrator now marks such ranges done before
leasing, and runRange reports them done without fetching.
- Some old ranges come so slowly that one XOVER of 20k headers takes over
two minutes: five ranges failed on "NNTP reply timed out". The relay
pool's timeout is SEED_NNTP_TIMEOUT_MS (default 10 minutes, the node's
HTTP timeout).

The seed API keeps a pool of NNTP connections (SEED_NNTP_CONNECTIONS) and
serves GET /api/v1/seed/ranges/:id/chunk?from=&to= for leased ranges:
the gzip stream the news server sent, passed on unopened. seed:node fetches
that way by default (SEED_FETCH=relay), so a node needs only a token and
SEED_CONNECTIONS; SEED_FETCH=direct keeps its own NNTP connections. All
fetching then comes from the indexer's IP (the account allows two).
