  "notes": [
    "<code>rails</code> and the emit lanes BOTH serve campfire's message fragments from a cache — Rails from Redis (<code>cached: true</code>), the emitted tree from its own process-local store — so the deployed lanes compare like with like. Until 2026-09-07 the emit had no fragment cache and this page carried a <code>rails-nocache</code> column so the comparison was renderer against renderer rather than emit against Redis; that column is now a diagnostic, requested by name, and is not published here.",
    "The deployed lanes are what each project would run on this box. <code>rails</code> is once-campfire AS ITS OWN DOCKERFILE RUNS IT: Thruster in front of Puma, <code>(processor_count * 0.666).ceil</code> workers x 5 threads from its own <code>config/puma.rb</code>, jemalloc preloaded, resque-pool alongside. <code>ruby</code> is the CRuby emit in the same Puma shape with the same allocator; <code>spinel</code> is the binary with its workers autodetected.",
    "<code>ruby</code> IS A MATCHED-SHAPE RUNTIME COMPARISON, NOT A DEPLOYMENT CLAIM. It runs Rails' worker count so the number is not a core count, but the emitted tree's Action Cable registry and its job queue are both in-process: at more than one worker a broadcast reaches only the subscribers sharing a process with the poster, so campfire could not actually run this shape. Its deployable CRuby shape today is one worker — the <code>ruby-1p</code> row, read it against <code>tobi</code> for the deployable comparison; one process serving every core (Falcon on Ractors, the shape <code>spinel</code> already has) is the planned replacement. <code>spinel</code> needs none of this: one process, green threads, one shared registry — which is why it is the emit lane the WebSocket tier can measure at its full worker count.",
    "<code>ruby-falcon</code> is the SAME emitted tree and <code>config.ru</code> as <code>ruby</code>, served by Falcon (the emit's <code>falcon.rb</code>: forked workers, the same count and allocator, cache hits answered ahead of Falcon's Rack adapter) instead of Puma: the server <code>tobi</code> runs. It isolates what the app server costs. Falcon is added to the emit's bundle by this harness, at the version tobi's lock pins; the emitted Gemfile names only Puma, and the WebSocket phase still runs Puma.",
    "The <code>-1p</code> lanes are the diagnostic, and what they pin is ONE CPU rather than one process — CRuby needs a process per core because of the GVL, while the binary is a single process either way and varies its OS worker count instead (<code>SPINEL_WORKERS=1</code>). They exist because a deployed number cannot say WHY it landed where it did, so these rows separate \"their runtime is slower\" from \"we gave them fewer cores\". Read them per lane-family: <code>ruby</code> and <code>spinel</code> differ from their <code>-1p</code> twins in worker count and NOTHING else, but <code>rails-1p</code> also sheds Thruster and resque-pool, so its delta is not attributable to cores alone. <code>ruby-1p</code> is ALSO the emit's deployable CRuby shape: one Puma worker, so one cable registry and one job queue, the shape the WebSocket tier runs it in.",
    "Known omissions, stated rather than discovered: the WebSocket phase's rails lane runs Puma with campfire's worker count and its allocator but WITHOUT Thruster and resque-pool, and no lane terminates TLS.",
    "MEMORY IS THE SERVER PROCESS TREE, and the rails lanes keep part of themselves outside it. Their fragment cache, their Action Cable adapter and Resque's queue all live in a system Redis (~16 MB RSS here) that is nobody's descendant and so is in no lane's number — while the emit lanes hold their equivalent inside the measured process. Throughput is unaffected: the rails lanes pay for every Redis round trip in their req/s. Counted for rails: Thruster, the Puma master and its workers, resque-pool and its workers.",
    "<code>tobi</code> is <a href=\"https://github.com/tobi/campfire-once-ruby-ractor\">tobi/campfire-once-ruby-ractor</a>: campfire ported BY HAND to plain Ruby, no Rails, served by Falcon from worker Ractors in one process, with in-process job and cable Ractors. It is the measured answer to \"how fast can careful Ruby serve this app\", and the target for the emitted <code>ruby</code> lane. It reads the same seeded database. Its deliberate differences from Rails (header-only CSRF, so its pages carry no tokens; part-hashed ETags; fewer cookie writes) are listed in its README.",
    "The CRuby fragment store is PER PROCESS, so the <code>ruby</code> lane holds one cache per worker where <code>spinel</code> holds one for the whole binary."
