# AGENTS - Cryptography Module

## Working Directory
- `src/Cryptography/**` (crypto core, plugins, profiles, tests).

## Required Reading
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/platform/architecture-overview.md`
- `docs/modules/cryptography/architecture.md`
- `docs/modules/cryptography/README.md`
- `docs/modules/cryptography/multi-profile-signing-specification.md`

## Engineering Rules
- Deterministic serialization and signing; no nondeterministic inputs.
- Respect offline posture; no network calls in crypto paths.
- Validate inputs and fail closed on verification errors.

## Testing & Verification
- Tests live in `src/Cryptography/__Tests/**`.
- Add vectors for signing/verification, negative cases, and determinism.

## Sprint Discipline
- Log cryptography decisions in sprint Decisions & Risks with doc links.
