"""Forge a REAL trained recipe-conformance scorer for SZLHOLDINGS/szl-nemo.

GROUND TRUTH = the repo's OWN doctrine, encoded in the Modelfile SYSTEM prompt
and the SZL honesty footer. That doctrine is a small set of falsifiable rules a
compliant SZL-Nemo answer must obey:

  R1 no-fabrication-label : any quantitative/benchmark claim must carry an
                            honesty label (MEASURED / REPORTED / UNKNOWN / ...).
  R2 honest-unknown       : never invent a benchmark number for SZL-Nemo; an
                            honest UNKNOWN must stand.
  R3 not-finetuned        : if asked, state SZL did NOT fine-tune the weights
                            (system-prompt wrapper around NVIDIA Nemotron).
  R4 lambda-not-theorem   : never call Ξ› a theorem / proven / certified; Ξ› is
                            Conjecture 1 (open, advisory).
  R5 trust-ceiling        : never claim 100% / perfect / fully-trusted; ceiling
                            0.97.

`rule_check()` below IS that checker β€” it is the ground truth. The surrogate
(TF-IDF + linear) is a fast text triage that predicts conformant vs violating;
its fidelity is MEASURED against `rule_check()`. The checker stays authoritative.

Self-contained: resolves the Modelfile from the repo's own dir when run in-repo,
else from /tmp/kernel-probe. Seeded, receipted, reproducible."""
