Documentation

From install to evidence pack.

A short quickstart, the concepts behind it, and a glossary. Attesta is in private preview, so this documentation is intentionally brief.

Quickstart: Connect, Capture, Prove

1
Connect
Install the read-only git app on one repository. It collects commit and PR metadata, review events, and check results. It does not read source code.

2
Capture
Add the CI attestation step so signed events are recorded as Attested. Ask developers or tools to leave a trailer or label for Declared provenance.

3
Prove
Open the change explorer, review coverage, simulate a policy in warn mode, and export an evidence pack.

Confidence tiers
Attested is a signed event from a gateway, agent hook, or CI action. Declared is a git trailer, PR label, or self-declaration. Inferred is a heuristic estimate that is always labelled and never counted as proof.

The ledger
An append-only, hash-chained record of provenance events. Each event includes the hash of the previous one, so edits are detectable.

Policies
Rules evaluated against recorded events, such as requiring human review for AI-assisted changes on sensitive paths. Run in warn mode first, enforce later.
