Subject: [PATCH] chore: run the offline test suites in CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This repo ships 12 offline test_*.py suites that need no API key and
make no paid calls, and nothing was running them. Copied decay-pin's
workflow verbatim — same layout, same uv toolchain — and added the
badge the repo had already earned.

All 12 suites verified green locally before wiring this up.

 Hobby-scale, pre-committed reproduction of **"Obey, Diverge, Collapse"** (arXiv 2607.04537): the claim that code LLMs recognize a wrong-location repair instruction as incorrect, follow it anyway, compound ghost errors across iterative repair passes, and land in a corrupted state that self-guided repair cannot recover — not even back to the original buggy baseline. Fourth in a lineage of reproduce-and-measure projects (forge-gap → decay-pin → lossy-wall); the target paper is days old, unreplicated, and its promised code appendix is absent from v1, so every prompt, filter, and gate here is independently built and disclosed.
 
 **Status: v1 COMPLETE — the chain is closed end-to-end (M4 closed 2026-07-11).** Measured on two cheap models — deepseek-chat-v3.1 and qwen3-coder-30b-a3b-instruct — over a frozen 186-problem RunBugRun bank, with every verdict rendered by a script written and dry-run **before** the paid data existed. Lifetime spend: **$1.4244** against a $5.00 guard.
