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.

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).

- seed:node logs in to NNTP before taking a range and keeps the connection
across ranges (replaced after 2 minutes idle or a failed range). A node
that can't reach its news server takes no range: two ranges were set
aside as failed while an office node's tunnel was being set up
(ECONNREFUSED 127.0.0.1:1563, five leases each). After an IP-address
limit refusal it waits 5 minutes.
- NNTP_TLS_SERVERNAME: the hostname the TLS certificate is checked
against when NNTP_HOST is a tunnel ("Hostname/IP does not match
certificate's altnames: Host: localhost").
- seed-node/README: the IP-address limit and tunnelling.

A seeding node that waited over two minutes for the seed API (restarting)
had its idle NNTP connection closed by its own timeout, and gave its range
back. Now the timeout runs only while a reply is awaited.

- lib/nntp/xover_client: a minimal one-connection client for seed:range
with XFEATURE COMPRESS GZIP (a zlib stream after "224 … [COMPRESS=GZIP]",
then a "." line; 420 for an empty range). About 6x less header traffic.
Overviews come out with the field names nntp-js uses.
- SfvService.claimAll: one sfv_entries lookup per stored batch.
- Fragments go through the regular ingest path beside fetching (at most
two batches in flight); a failure fails the run at the end.

Spotnet (CONCEPT D29):
- Index free.pt fully and import spots with their descriptions, categories
and NZBs; a spot renames its release, since Spotnet names are more
trustworthy than names derived from subjects.
- Find passwords in spot descriptions too, and tell "needs a password we
have" from "needs a password we don't have".
Content inspection:
- List the contents of 7z (.7z.001) archives, SFV sets, nicovideo uploads
and other archive-like files; mark yEncBin .bin containers as encrypted.
- Take real names from yEnc headers for randomly named files, and merge
uploads that were split across posts.
Storage (D31, D32):
- Store segment lists zstd-compressed behind the FileStore accessor.
- group:backfill indexes older headers at low priority and pauses when
the NVMe or HDD part of the database gets too large.
Grouping (D35, D36):
- Lone header segments wait in staged_segments until a second segment of
their file arrives, which drops the per-article junk binaries.
- Counter grouping joins random-subject uploads by poster, [i/M] counter,
part count and day.
Search and maintenance (D33, D34):
- A trigram-indexed search_text column, smaller indexes, estimated stats.
- Passes that clean up nonsense names; weekly index maintenance; GC budgets
per kind.
- Web UI: grey out stale results while a search runs and cancel superseded
requests. Count only up to 1,000 matches for the page, which made filter
clicks take seconds (Newznab keeps the 10,000 cap).
