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 lease ends.

The NVMe floor is 4 GB since Oct 23; at 12 the prober had claimed nothing
since Oct 23 15:30 (7-10 GB free).

A full round took 35-38 min of each hour and grew with every inspection
the prober added. Triggers note changed releases in judge_dirty; the
judge judges those (and releases a file hash of theirs tipped to
repeated) by every rule, and every release in a daily full round for
what time changes.

At ~200 articles/s what the prober stores (inspections, par2 file lists,
the WAL) took ~0.8-1.1 GB an hour of homelab's root, and nothing stopped it
at the 10 GB floor. Below 12 GB free it claims nothing (resumed 1 GB above):
the lanes go dry and its share shrinks to its minimum.

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.

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.

At 50 exactly the coordinator still got 502s now and then: a hedged request
closes its connection and opens another while the old one still counts.

Coordinator 38 + its plain connection + prober 10 + spotter + spot inspector:
the spot inspector got 502 Too many connections.

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.
XoverClient.head(); PROBE_CONNECTIONS default 10.

Every commit waited on the WAL in ./pg on the HDD (WALWrite; the HDD 100%
busy, 56–70 ms a write): prober flushes and claims took most of each minute.
A PG_WAL_DIR volume (default /var/lib/usenet-rebuild-wal) at
/var/lib/postgresql/wal, with data/pg_wal a symlink to it (set up by hand
once, with Postgres stopped).

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.

Ranges marked `capture` keep their XOVER chunks in CORPUS_DIR
(corpus/<group>/<start>-<end>/, edge-bench's layout, range.json once
complete; only chunks that inflate). The prefetcher reads a stored chunk
instead of fetching it, so a reset re-indexes them without the news
server; a chunk a worker reports corrupt goes from the corpus too.
edge-bench gets --releases (release chunks without payload, with their
first subjects) and ships in the edge image; deploy/corpus_sweep.py marks
more ranges (capture), replays the corpus with the deployed build (replay)
and reports suspects and the change since the previous build (report).

The node API (leases, hour-long streams, batches of up to 256 MB JSON
parsed in-process) shared the web process with the catalog API, Newznab
and the web interface; voyager 1 had to make the same split on
2026-10-06. HTTP_ROUTES picks a process's routes (node, public, all by
default): compose service node-api (same image, port 3335 on the compose
network) serves the workers, web the rest. The workers' COORDINATOR_URL
points at node-api; deploy.sh stops edge before recreating node-api.

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.

Dockerfile with two targets: app (compiled AdonisJS, production
dependencies, Node 24.16 as in CI) and edge (the Rust worker, cargo
caches as build mounts). deploy/compose.yaml, project usenet-rebuild:
postgres (data on the HDD, catalog tablespace on the NVMe), migrate,
web, coordinator, edge; edge-ts and ace behind profiles.
deploy/deploy.sh (~/bin/deploy-usenet-rebuild on homelab): fetches the
commit (must be on rebuild), builds, migrates, recreates web,
coordinator and edge (the worker stopped first), never postgres.
CI deploys a push to rebuild that passes: the deploy key's forced
command passes "deploy-rebuild <sha>" on. A push to master no longer
deploys from this branch's workflow. deploy/README.md.
