proof-derivation-forensics

Family-G proof & derivation integrity forensics: does a THIRD PARTY's written proof/derivation actually establish its theorem, or does it skip an obligation, assume its own conclusion, take an invalid step, drift a symbol's meaning, or smuggle an unstated assumption? Decides from the WRITTEN proof/derivation — verdict-bearing at L1 (the LaTeX source; PDF-extracted math is unreliable, so an L0 PDF-only run surfaces info only) — never asserts 'fabricated', only that the step shown does not hold. A fresh cross-model reviewer reads the theorem/proof + an extraction-only obligation scaffold and proposes per-obligation findings, each span-anchored to the evidence ledger (claims.json); reviewer≠adjudicator. Emits proof-derivation-forensics.findings.json; NEVER computes the verdict. dimension=proof, can be critical. Triggers: "proof forensics", "check this proof", "derivation integrity", "audit the math", "证明审计", "推导有没有漏洞".

# Proof & Derivation Forensics — does the written proof hold?

Audit family **G (proof & derivation integrity)** for: **$ARGUMENTS** (requires
`claims.json` from `/evidence-ledger`). A fresh cross-model reviewer reads each
theorem/proof and proposes span-anchored findings; this skill writes
`proof-derivation-forensics.findings.json`. The deterministic adjudicator — not this
skill — computes the verdict.

> 🔒 **Do not wrap this skill in `/loop`, `/schedule`, or `CronCreate`.** It is
> verdict-bearing input — it proposes the findings the deterministic adjudicator
> turns into the report. Re-firing it on a wall-clock timer adds no signal: its
> output changes only when the **paper / ledger** changes, not with the clock.
> Schedule the *external wait that precedes it* — ledger built → audit **once**.
> (Mirrors ARIS's external-cadence doctrine.)
