Targeted audits for consolidated research tracker

[DomTheDeveloper]

Runs three independent pinned-Lean jobs against the active Formal Conjectures branches:

1. Erdős Problem 545 exact counterexample module;
2. Sun Conjecture 2.6 finite kernel checks and analytic proof;
3. A280831 parametric-family module.

The jobs reject placeholders and trust escapes, compile only the relevant files, enforce the axiom policy, and upload exact transcripts. This is an iterative audit lane; final green versions will be pinned to immutable source SHAs.
