The proof pile — real agent runs, real verdicts,
accumulating every night

A real AI coder (zai:glm-5.3) does real open-source work. Every run is judged four ways: independent hidden tests, a normal CI, the agent’s own final message, and the ranex gate (signed proof against a checklist frozen before the agent started). Dogfooding appends new proofs nightly; the pile only grows.

The difference, in one picture

The claim never changes. What changes is whether anything backs it up.

WITHOUT RANEX 🤖 “Done! All tests pass.” its word. nothing else attached. 😃 “Great — merging it.” if the agent was wrong or gamed the tests, you find out in production. WITH RANEX 🤖 “Done! All tests pass.” same agent, same claim. 🔒 the claim must pass a frozen checklist with signed proof — verified ✓ or blocked ✗, in writing.

What the gate caught — the classic attacks

Fault-injected on real code and labeled as such: the two classic gaming attacks on a real solved run, and the external-repository variant — a changed subject refused with yesterday's green evidence still on disk.

The released kernel on a clean external repository

Not the working tree, not an agent: the published tag, installed the documented way, brought to a real third-party repository and judged there. Green evidence survives exactly until the subject changes — then it is refused by name until the work is redone. Raw receipts below.

The pile’s bottom line, so far

0
times it blocked work the hidden tests confirmed (11 harness faults excluded)
7/7
attacks caught: deleted tests, stale proofs — each named, each verifiable
ms
to re-verify any past completion from its chained record — the audit a scrollback can’t do

Honest scope: attacks are fault-injected on real solved runs and labeled as such; in the natural runs so far the agent was honest, so the pile’s value there is certified agreement plus the audit trail. The pile grows nightly — every new night either adds another clean proof or catches something real.

The kernel, evolving — measured from git history, not claimed

Every point on every graph is computed from this repository’s own history at that commit: the kernel’s total independent code paths (McCabe), the registered proof scenarios, the archived real-world proofs, and the open-findings ledger. The graphs refill every dogfood cycle — a flat line here would mean the loop stopped working.
