Evidence brief

A reproducible test for AI-agent repository exposure.

CapitalGuard 1.3.0 detected all six declared exposure classes in a disposable synthetic repository. Across six emitted evidence artifacts, zero fixture markers appeared.

This is evidence of behavior on the disclosed fixtures, not a guarantee that every repository is secure.

What was tested

Six declared synthetic exposure classes.

The repository was deliberately constructed with inert markers, invalid credentials, and commands that were declared but never executed. The run did not contact a network or a real customer repository.

What was observed

The output is independently inspectable.

  • Declared exposure signals were present for each disclosed fixture.
  • Each inert marker stayed out of the report, A-BOM, event chain, evidence bundle, and AccessGraph.
  • Fixture definitions, case results, release manifest, and SHA-256 digests are public.
