01 / The rule

What SLSA v1.0 requires

Software producers and build platform operators that want to show build integrity, and consumers verifying artifacts.

  1. 01Build L1: follow a consistent build process and generate and distribute provenance describing platform, process and top-level inputs.
  2. 02Build L2: run builds on a hosted build platform that signs the provenance.
  3. 03Build L3: use a hardened platform that isolates runs and keeps signing secrets from user-defined build steps.
  4. 04Consumers verify provenance against expected builder, source and parameters before use.

02 / In this sector

In a legal AI workflow

Build provenance can apply to model training or packaging pipelines that produce AI artifacts, but SLSA does not address models or data specifically.

Usually asked by

General counsel and litigation support.

  3. 03Verification summary attestations (VSAs) or verifier logs

Optional evidence · where Planisphere fits

Keep a record anyone can check

When your team meets a duty, Planisphere can seal the event it reports as a receipt.

01 · Your teamRecord the event

A disclosure shown, a review signed, a model change approved: the event your system reports.

02 · PlanisphereSeal it

The event becomes a sealed receipt, dated and attributed to whoever is signed in.

03 · AnyoneCheck it

Paste the receipt into Verify. No account or key.

A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.
