Connections fetch chunks round-robin from several starting points of one
group at once, so each era sees the same server load; per era: seconds
per command (mean, median), articles/s per connection, bytes per article.
On a.b.boneless (2 connections, 10 min): 2008 24.9k, 2011 28.0k, 2019
22.6k, 2026 17.9k articles/s per connection; medians 2.3-3.0 s, means set
by a tail of slow commands (up to 41 s).

libdeflate inflates a chunk whole, in half the time of zlib-rs (1.09 ->
0.51 s per boneless range); memchr finds line ends and tabs with SIMD.
The per-article timers are gone. Boneless 2026 ~700k headers/s, ath 2013
~920k; all three captures still identical to the TypeScript.

Each with its regex/chrono version as the reference in tests; check.ts
still finds all three captures identical. Boneless 2026 ~500k headers/s,
ath 2013 ~650k.

The suffix and remainder regexes were most of a new file's description
(333k on boneless 2026): now plain byte matching, with the regex versions
kept as the reference in a test of tricky names and subjects. mimalloc
for the many small strings. Boneless 2026: 360k -> 495k headers/s;
check.ts still finds the outputs identical on all three captures.

The RangeIndexer path of edge:bench (inflate, scan, owner rule, segments,
file aggregation, cut-off, rules, release identity, chunk encoding v2,
probe candidates) as a Rust binary over a captured range, with JS
semantics where they matter (\s, trim, \b, parseInt, lastIndexOf, UTF-16
lengths). check.ts runs the TypeScript RangeIndexer on the same capture
and compares every output: identical on all three captures (releases and
their decoded payloads, samples, candidates, rule counts, fragments),
after mapping Date headers ending in UTC to GMT (chrono follows RFC
5322; Date.parse takes UTC, a quarter of a.b.boneless). Compressed
payloads differ by <0.1% in size (zstd framing), not in content.
First run on boneless 2026: 360k headers/s and 228 MB peak (TypeScript:
~217k/s, ~0.7-0.8 GB).
