Engineering evidence
Here is what I claim, the evidence behind it, and its limits. Verify it yourself: every public artifact links to the exact commit it was verified at.

How to read the badges
Verification
- Designedenvironment:Lab
- A design doc or ADR states the intended behaviour; no working code yet.
- Implementedenvironment:Lab
- Code is merged at a tagged release and runs; no automated test asserts the claim.
- Tested in CIenvironment:Lab
- An automated test in CI asserts the claimed behaviour, including a failure case where relevant, and passes at the verified commit.
- Measuredenvironment:Lab
- Tested, plus a repeatable experiment committed as machine-readable output with method, environment and raw data.
Environment
- Lab
- Local machine, local clusters or CI runners.
- Reference
- Validated design or infrastructure code that has not been deployed.
- Deployed
- Running in a real, reachable environment I operate.
- Production
- Real users or traffic: employment history, or a project with real usage.
Context
- Employment
- Real work for an employer, sanitized. Source code is proprietary.
- Personal lab
- My own public repositories.
- Reference architecture
- Reference architecture: designed and tested, not deployed.
- Open source
- Contributions to projects I do not own.
- Employment + proprietary
- Capped at Implemented: a test nobody can inspect is not public evidence.
