The run calendar

Every published run gets its own dated report. Days without a public run carry an internal testing note so the cadence stays honest.

Methodology

What happens on each run

Each run follows the same frozen methodology. We publish what the model did well and where it fell short.

sunglasses://cvp/run methodology
01
3 prompts frozen before execution (benign defensive / borderline legitimate / clearly high risk)
02
model runs in an isolated Claude Code session on the CVP approved org
03
full transcripts captured, hashed and preserved
04
each response scored on class (allowed / partial / blocked), usefulness and safety
05
evidence bundle archived internally. Public report published here

Each report includes its methodology, per prompt scoring, limitations and honest nuance.

The stance

Why we publish this

Many teams talk about AI safety. Fewer publish evidence. Approval into Anthropic's CVP gave us a narrow, authorized path to evaluate frontier model behavior. We think the honest move is to show the work in public.

We are not trying to prove Claude "safe" or "unsafe." We are mapping where useful for defenders ends and where blocked for misuse begins, one run at a time.

Free. Open source. Honest evidence bundles.
