  "claim": "The headline figure for the jev-linkmap run is $0.27 for 566 pages. That is the cost of the mapping pass alone, with the rubric already trained. The run that produced the 287 links now live on the site also paid $15.51 to tune the rubric and $2.07 for the editor pass, so the shipped artifact cost $17.86 — 65x the headline per kept link. Every figure below is summed from the repository's own run files.",
  "method": "Summed from stas4000/jev-linkmap at commit 58f636e. Mapping pass: out/report.json (jev.cost, jev.pages, jev.decisions, links_placed). System 2 loop: the frontier.cost field of runs/block1, runs/block2, runs/holdout-v1, runs/holdout-v2 and runs/holdout-v3 (five referee passes over 24 pages each), plus the cost field of runs/block1/system2.json and runs/block2/system2.json (two rubric rewrites by claude-fable-5-1). Editor pass: the summary block of out/linkmap-verified.json. The full-Opus-pass estimate is the mean referee cost per page over those 120 block page-judgements, multiplied by 566; out/report.json instead extrapolates from the 8 pages that landed during the race, which are the shortest pages on the site, and so reports $15.21 and 55.7x for the same claim.",

  "note": "The $15.51 is one-time per site and the $0.27 recurs per run, so the second map of this site really is 240x cheaper than an Opus pass. The first one is 3.7x. Tuning equals the cost of mapping the entire site at 32,147 pages; this site has 566.",
