# Excititor Attestation Tests Agent Charter

## Mission
Validate Excititor attestation signing and verification with deterministic tests.

## Responsibilities
- Cover DSSE envelope creation and verification logic.
- Exercise transparency log and signature verification paths.

## Required Reading
- docs/modules/excititor/architecture.md
- docs/modules/platform/architecture-overview.md

## Definition of Done
- Tests cover core success/failure paths for attestation components.
- Fixtures avoid nondeterministic inputs.

## Working Agreement
- 1. Update task status to DOING/DONE in the sprint file and local TASKS.md.
- 2. Review this charter and required docs before coding.
- 3. Keep outputs deterministic (ordering, timestamps, hashes) and offline-friendly.
- 4. Add tests for negative/error paths.
- 5. Revert to TODO if paused; capture context in PR notes.
