+// build-judge-payloads.mjs — deterministic fan-out prep for the per-claim
+// groundedness judge bake-off. Turns the blind claim manifest + a judge prompt
+// template into 45 ready-to-dispatch subagent payloads (one per file), so the
+// fan-out is reproducible instead of hand-assembled in main context.
+//
+// The v3 fan-out grouped claims by file MANUALLY at dispatch time; that made the
+// exact payloads non-reproducible. This script fixes the construction: same prompt,
+// same per-file claim grouping, every run — so v3.1 (and any future arm) is
+// apples-to-apples and a fresh session can resume with one command, no improvising.
+//
+// Pure string assembly — no LLM, no network, no math. Reads:
+//   data/judge-bakeoff-claims.json   (blind manifest from extract-judge-claims.mjs)
+//   <--prompt>                        (judge-claim-prompt-vN.md, with <FILE>/<CLAIMS>)
+// Writes (with --write):
+//   data/<--out>                      (array of {file, claim_count, prompt})
+//
+// Usage:
+//   node scripts/kb-eval/build-judge-payloads.mjs --prompt judge-claim-prompt-v3.1.md \
+//        --out judge-bakeoff-payloads-v3.1.json [--write]
+//   (default: print per-file claim counts + a sanity sample; --write persists)
