Public proof
Contract surface evidence before readiness.
This proof summarizes a real GitHub Actions run where Abizor recorded a Python top-level public function signature change as replayable evidence before readiness.
What was verified
Abizor saw a public function signature change in CI.
Abizor ran in GitHub Actions on pull request #4 in the Abizor repository.
The run changed a public Python function signature and Abizor recorded that change as a contract_surface fact.
The change appeared in the proof record and in the human-readable CI summary before readiness.
Detected change
One public Python contract changed.

After:

It carried public surface evidence into readiness.
- Detected a Python top-level public function signature change.
- Recorded a
contract_surfacefact in the event log. - Included the public surface change in the summary and generated PR comment body.
- Included the
contract_surfacesource fact in readiness evidence. - Reached the merge boundary without executing merge.
Output
The proof showed the contract change before merge.

What this proof does not claim.
This proof did not create or merge the pull request.
It did not post a GitHub PR comment, deploy code, or use a hosted app, hosted API, dashboard, billing flow, or GitHub App.
It does not claim broad API compatibility, OpenAPI support, TypeScript support, database-schema support, security review, compliance, or contract-change blocking policy.
