nx_forge_curves.nx -- PASS@N CURVE HARNESS (dossier N3's remaining adversary: "per-tier pass-at-1 vs pass-at-N curves must be published so an insufficient tier is measured not asserted"). Runs the ENGINE's pure sampling stage (maxc=1, no repair advantage) per fbench task with nsamples=N and records AT WHICH SAMPLE k GREEN landed (engine rc 100+k) or -40. pass@k for the row = 1 if greenk>0 && greenk<=k. Emits append-only rows to knowledge/forge/pass_curves.tsv: CURVE|tier|task|nsamples|greenk|rc|us (derivable into pass@1..pass@N columns by any reader; the /compare/coding page consumes this). The pfx route (engine sample stage) makes N samples ~1 prefill + N generations = affordable. MEASUREMENT organ (expect_exit 0: the rows are the deliverable, RED runs are honest rows). usage: nx_forge_curves <tier-label> <port> <nsamples> <temp_pm> <chat> license_tier: ORIGINAL expect_exit: 0
