## 2. Core Architectural Primitives

1. **Ed25519 Steward Signatures (`manifest.steward_sig`):**
   Cryptographic proof of agent origin, payload integrity, and developer attestation via RFC 8785 JSON Canonicalization Scheme (JCS).

2. **Deterministic Context-Loop Gate (`deterministic.gate`):**
   Policy gate positioned outside the agent's LLM context window to prevent prompt injection and context window manipulation.

3. **Action Reversibility Classification (`action_reversibility`):**
   Worst-case action class classification governing execution approval pipelines:
   - `read_only`: Non-mutating data retrieval operations.
   - `soft_write`: Reversible internal state mutations.
   - `external_reversible`: Reversible external API actions.
   - `irreversible`: High-impact, non-rollback actions requiring explicit steward verification.
