The tiny-archive rule (dropTinyArchives, both indexers): a settled single
archive of one article and 2-100 kB under a release-like name, spaces
allowed, outside the exempt groups and without an e-book, subtitle,
crack, cover or sidecar word: the 2015-17 exe-stub flood in miniature,
1.66M catalog rows (LOG.md (131), (133)).
PendingLadder.discard scanned every waiting row against the dropped
signatures and classes, 9+ minutes a sweep inside the claim, stalling
every lane: now driven from the dropped classes and signatures into the
indexes. The namer feeds the indexer the span's overview text chunk by
chunk (one string of it topped V8's limit) and gives up spans over 3M
articles. Migration 7000: a partial index on the taken probe candidates
for the prober's start.

The first run scanned the 58M-row pending table on the HDD once per
6-hour window and starved the prober and the batch store. Now one scan
classes the finished rows and seeds the record, and the waiting rows go
by windows of created_at through their index. The prober's start puts a
previous run's claims back with a status scan of the same table, 20+
minutes after every deploy: a partial index on the taken rows (migration
6900) makes it instant.

The production dry run of releases:readable flagged 5.37M of 19.8M rows,
and its first sample held real names: "CrossStitcher - Issue 440",
"SchiffsModell", "FastFilms 2.04", "BestCrypt NP v4.0", "SmithsWork",
"Laura15Juli2026". Two CamelCase words with few vowels have four runs and
no lone letter: a scramble now needs five runs, a lone letter or an inner
capital run besides its few vowels; the consonant-run clause is gone
(it counted y); a token whose letter runs are all words or acronyms with
numbers between them is neutral. On a 49k-row production sample the
flagged share went from 27.4% to 26.4% with the letters-only flags all
scrambles; the evaluation sets are unchanged (LOG.md (129)).

The prober names 6% of the unnamed releases it finishes and the pending
queue (44M) grows eleven times faster than it probes. A sample of 44,530
finished pending rows shows the headers predict a name: size bucket, name
shape, completeness, tool and group separate 0% classes from 95% ones,
while the learner keyed on tool and group alone (LOG.md (130)).
- lib/release/classes.ts, names::pending_class, SQL pending_class():
a release's class (size × shape × partial, 1..70), the three in step.
- Migration 6800: pending_releases.klass and target_bytes (the first
target's article; candidates carry bytes now), pending_classes with
each class's climbs, names, waiting and verdict, the claim's index.
- The ladder claims the classes with the best record first (a prior for
the unexplored, at most a quarter of a claim from one), the cheapest
target first within one, then the oldest of the rest; records classes
like signatures and drops them at the same thresholds; discards their
waiting releases. Claimed rows sorted in code: an UPDATE returns none.
- The rule set's droppedClasses: the edge keeps unnamed releases of a
dropped class out of the pending store (counted as garbage), the
explored sample excepted.
- hash_twins.ts: a probed file whose first 16 KiB and size match a named
catalog release's names a pending release the probe didn't, and sets
the inner name of a catalog release without one.
- pending:classes classes the rows from before and seeds the record from
the finished ones; rules:classes publishes the dropped classes;
releases:readable also marks the rows' candidates unreadable.

Searches with the readable filter on returned scrambles: with a random
4-letter query nearly every hit was one ("Zx5AjNaK-mh7CFg6Hf8uu",
"Description - Lt5nHjlo3RiuBb3C", "PsNdnYiugfZ", "bd5b...-addon"), and
15% of a 6,000-row sample of the catalog's readable names were. looksRandom
knows single-token shapes only; separators, spaces, a random "extension"
of any length and a packaging word hid the rest.
isUnreadableName (lib/release/readable.ts) and names::is_unreadable_name
read a name token by token: words (one case or Capitalized), scrambles
(letter/digit and case switches, lone letters between capitals, inner
capital runs, few vowels, hex) and neutral tokens (digits, codes like
S02E10 and 1080p, CamelCase, packaging words); a name is unreadable when
its scrambles outweigh its words. Scene tags' "i" for "I" and the
NZBSPLIT hash are read as such. On the evaluation sets: 554 of 559
random-search names caught, 0 of 630 real names flagged (LOG.md (129)).
The edge's readable flag and the prober's inner names use it; the drop
rules keep looksRandom, which is narrower. An unnamed release goes to the
pending store (decision f), so more of the obfuscated groups' releases
wait for a probe now. releases:readable clears the flag on the existing
catalog's rows by name (a dry run by default).

The first five hours in production (LOG.md (128)) dropped 522 passworded
videos of one a.b.erotica poster: ROT13-named volumes (".cnegN.rar" is
".partN.rar") of 1-270 MB in 258 kB articles to two groups, which the
article-size leg took for stubs. The cap that X and W already had now
applies to A as well (the catalog sample has 6 A-leg hits over 100 MB,
4 of them exe-only), and a ROT13 volume name is no single archive.

The judge gets each file's articles seen and bytes, and whether the window
closed on the release. A settled release of one unsplit archive posted to 2+
groups is dropped as a stub archive when its articles are <= 256 KiB with the
release >= 1 MB, or it is in 4+ groups, or by a webmail poster (those two
under 100 MB); releases touching music, e-book, comics, tabs or fonts groups
are exempt. A one-article archive of 100 kB-1 MB under a release-like,
unscrambled name without spaces or an e-book format is dropped as a nonsense
piece. Both switched by the rule set (dropStubArchives, dropNonsensePieces),
mirrored in lib/rules, sampled like every drop (LOG.md (123)-(127)).

One article of a multi-part file under a name like "nYDeXeF49dieZ1J7flK-JFzZ3j.ZEDsr" or
"bslXlwgPiqZadhRa" (a random subject and poster per article, with fake counters) was a release:
looksRandom misses these names for their separators. 160k of alt.binaries.storage's 162k
non-Bob releases, and about 60% of all single-article releases in a 2% sample.
looks_scrambled / isScrambledFile: at least half the stem's letters and digits in tokens of 5+
that switch case or letter/digit 3 times or more (93% of the storage spam). Used for lone
articles given up before the block's end only; at the end the strict looksRandom stays, as the
rest of such a file can be in the next block. The namer's re-index (partialFiles) does the same.
The prefetcher's corpus fill skips groups that aren't active.

"^zed" finds "Zed Dead", "The_Zed_Files", not "Facialized": a regex on
release_texts, (^|[^[:alnum:]]) before the word, which the trigram index
serves (homelab: 551 texts for ^zed against 6,606 for zed, 35 ms warm).
Words without ^ match anywhere as before; the search box says so.

A poster's counter without its "[" ("… Facialized 002/477] - 0177.jpg")
left "… Facialized ]" as the release name (11286967). displayName (TS) and
display_name (Rust) drop unmatched brackets from subject and post names
only; the identity key keeps the remainder as it was, so no release splits.

The pending namer's TypeScript re-index gave a file short of parts on the
server to the range path's fragment rule, so a partial release the edge
wrote (Bob's hex-named uploads in chello, ratcave, font, storage) never came
out again: 10 of 148k named releases moved. RangeIndexer's partialFiles
keeps such a file in its release, marked partial; tools/namer_check.ts
replays sample rows from the corpus (10 of 10 found with it, 1 without).

The next claim started at half a batch of four pipeline rounds a lane,
3-6 s of work, while a claim takes 1.5-4 s and more; at 20-24 lanes the
lanes waited for candidates up to 19% of their time. queueLevels: the
claim starts below eight rounds of every lane's pipeline (~13 s) and
fills the queue to twice that. Taken candidates go back to waiting at
start-up as before, so a bigger queue costs nothing on a restart.

Every group is tiled from article 1 now: one range with status 'ancient'
covers what had expired on the server before the group was planned.
Nothing selects it (leases, prefetcher, corpus fill, tail merger all take
'planned'), the status panel reports it apart, the search's history stats
leave it out. Migration 6700 adds it for the groups planned before;
Planner.historyRows (now a pure function, unit-tested) for new groups.
The status bands are ordered by an explicit key: the ancient row at
priority 0 tied "history 0-999" with "window 0".

The sampling ranges in other years are capture too, at history priorities: they made a band each. The database
size walked the HDD partitions for minutes and the probe counts took 10 s on 11 M rows: dropped, and the partial
indexes' reltuples instead.

A group now has two lease lanes (migration 6600): `history` works the ranges the bounds hand out, `tail` the tail
planner's, each with its own holder, window, snapshot and takeover redo, so a thread on the tail never wades
through a group's history and a held group's tail isn't stuck behind it. The edge puts `--tail-threads`
(EDGE_TAIL_THREADS, 1 of 2+ by default) of its threads on the tail lane; the group routes take `?lane=`. The
lease order within a lane alternates the group with the most planned articles and the longest unheld one. The
takeover redo puts back only the lane's ranges the window did after the snapshot, and a group whose last range
is held by a holder gone quiet can be taken over.
`coordinator:status` prints the catalog's room, the ranges by band, the last hour's rates, the held groups with
their snapshots and the phase-2 backlogs. `tests/e2e` runs the real edge-node binary against the node API: the
corpus-fill race, a failed stream and the restart that restores the snapshot, a restart without the snapshot
file, a takeover (STREAM_CHUNK_WAIT_MINUTES is a setting now). CI builds the binary before the tests.

A release the window hadn't closed on at a lease's end is written provisionally
for its continuation to finish; the first run's range leases left 109k such
rows at their blocks' end edges, 606 of them complete, shown as still
collecting (release 10697). The coordinator now settles a provisional release
that is complete and quiet for six hours as the finish would: settled_at set,
its waiting probe candidates made claimable. Incomplete ones keep waiting.

A round added a row a group whenever 100k articles or 15 minutes had passed,
tuned for a tail leased within minutes; with nothing leasing the tail the rows
piled up (127k planned tail ranges of a median 14k articles, 97% adjacent). Now
a round grows the group's last range when it is a planned, unspooled, untaken
row at the tail's priority, up to RANGE_ARTICLES, and only then adds rows; a
range taken meanwhile gets the slice as a row. ranges:merge-tail (--dry-run)
packs adjacent planned, uncaptured, unspooled, untaken tail ranges of a group
and priority into ranges of RANGE_ARTICLES under the lease lock.

A plain stop and a chunk that doesn't inflate already posted the batch so far,
so the stop snapshot stood at a stored resume point; a failed stream (the
stalled one's "Peer disconnected") skipped the post, left the batch open and
lost the window with the snapshot refused. Now only a batch the coordinator
refused stays open.

The corpus fill claims chunks of a leased range ahead of the leased run (the
prefetcher's claim keys are per range and chunk), stores them in the corpus
only, and the run leaves them there. The stream looked at the corpus once per
chunk and then polled the spool only: when the store came seconds after that
look, the stream waited its whole hour and the worker lost the group and its
open batch (three groups on 2026-10-27, LOG.md (118)). Now the wait loop checks
both.

The lease bounds alone don't select a window: the history planner's oldest
buckets are priority 0-2 as well, so the window worker at 0..0 also took 2026
history at 0 (25k ranges in 40 groups, fetched live) while 1,739 ranges of the
2016 corpus window sat at voyager 2's leftover priorities (done when the window
was marked, planned again by the reset). With LEASE_CAPTURE_ONLY the lease, next
and the prefetcher's run-ahead take capture ranges only; the run-ahead now also
keeps to the lease bounds. Test: a group with history at 0 only isn't leased,
the history range after the window isn't handed out.

A live reply cut short (the server's compressed data ending at ".\r\n" at a
read boundary; the spool keeps what Corpus.write refuses) made the worker give
the group back without a snapshot, losing the window and the batch since its
last post (six times in the first 40 minutes on homelab). Now the batch before
the chunk goes out, the chunk is reported (fetched again, plain the second
time) and the range is asked for again from that chunk (RangeOutcome::Again):
the stream waits for the new copy and the window stays. Test: the coordinator
hands the same range back at its resume point after a corrupt report.

A worker thread leases a group and takes its ranges in article order through
one carried window; the coordinator keeps one cursor a group (group_leases,
migration 6500) and hands out the next range, the rules and nothing about
where the chunks are: the range stream serves a stored range's chunks from the
corpus file and a live one's from the spool. The window's snapshot (bincode:
the frontier, the open files, releases and albums, the upload numbers, the
batch-counter table) goes to the coordinator every EDGE_SNAPSHOT_MINUTES and
when the group is given back, and the next holder restores it; a takeover
after LEASE_TTL_SECONDS plans the ranges from the snapshot's article again.
The prefetcher runs ahead of held groups' cursors and skips chunks the corpus
has. LEASE_MIN_PRIORITY..LEASE_MAX_PRIORITY bound what is leased. edge-node
holds groups by default; --ranges keeps the old per-range path.

pending_ladder.ts claims the oldest waiting pending releases' next target
(par2, archive, lone, 7z-tail in that order) as at least PENDING_SHARE of each
claim; a usable name (the largest named file of a par2 set or a listing, or a
lone file's yEnc name, neither packaging nor random) hands the release to the
namer, no name the next target or the end of the climb; climbs count on
pending_signatures per (tool, group, poster) and (tool, group), and a signature
with 100 climbs and 0.5% named or fewer is dropped: its waiting releases are
discarded without a probe, the rules' sample excepted. pending_namer.ts reads
a named release's articles again from the corpus or by XOVER and writes it to

An unnamed release (no readable file name) is written to pending_releases

a batch by readable. The pending ladder (probes cheapest first, signature
verdicts, the move into the catalog) comes next. The replay report shows the

A release the window closed on with one file named by its stem or post, the
name with a number and no archive, volume, sidecar or random name, waits in
the album of its poster and template (the name's digit runs as #, the
extension apart) posted within the window of the album's first file; the
album closes a window after that span and is written as one release
(source album, no file total) named by the members' shared numbers, a lone
member as the release it was. The batch store writes an album's member
names as release_texts kind 6 (member). A counter total of 100 or more under
which one poster started 20 or more releases is a batch counter: those
releases get no file total.

edge-bench --group and replay:corpus take --to <article> next to --from, so a
replay covers one window of a group's history while the corpus holds others

window on homelab: every group whose window ranges are all stored is replayed
once into usenet_replay through the voyager-3 app image, 4 groups at a time,
looping while the corpus fill completes the rest.

replay:corpus runs edge-bench --group over a group's complete corpus ranges
in article order (one window, carried from range to range, finished after
the last range; edge/src/lease.rs holds the lease JSON the worker and the
bench share) and stores every batch through BatchStore as the worker
would, then reports releases finished, provisional, complete and the bytes
per header of the NVMe and HDD tables. Refuses a database not named
*_replay or *_scratch. The app image carries edge-bench; compose gets a
replay profile for homelab.
Design amended (REBUILD.md 1, 2, 5): the window is carried by one worker a
group, no block leases and no block merger; provisional writes stay for

The 512 candidates were the lowest ids at the lowest priority; a group's

The indexer finishes files and releases by posting time instead of the
range path: the frontier is the median Date of the last 1,024 plausible
dates (within 7 days of it; a run of 1,024 agreeing dates moves it), and
a release is finished, judged and written once the frontier is 24 h past
its last part, flagged edge when posted within a day of the block's start.
At the block's end the rest is written provisionally as edges for the
block merger. Files short of parts stay in their release (partial: the
store writes complete = false). Gone: fragments and the cut-off,
uploads_of (online now), check.ts and the fixture comparison; CI replays
the fixtures through edge-bench instead. The wire carries finished, edge
and partial.

Each release chunk is a release inserted once: release_key the SHA-1 of
the identity, the owner group and the first article (deterministic; no
numbering under a group lock), identity_key the identity's SHA-1 bytes,
poster_id and group_set_id through catalog_refs (cached per process),
source as a code (weak-stem added), the name into release_texts. A
finished release's candidates are claimable at once; a provisional tail
release is finished by a later chunk of its key, a finished one sent again
is left alone. Gone: joins into earlier releases and across groups, key
numbering, the group lock, the fragment merger. Interim: chunks, counts
and samples keyed by ranges.block_id, a range without a block gets one.
Readers follow: search (posters and group_sets joined, words through
release_texts, posters by id, source by code), the par2 merger, the
sidecar folder, the judge's scraped rule, the spot inspector, the spotter,
the NZB service, releases:regroup, edge:bench. Tests insert fixtures
through tests/functional/helpers/releases.ts; the suites pass again.
