# JEP Primitive Skills

**Atomic Reference Implementations of Judge, Delegate, Terminate, Verify**

## The Four Primitives

| Primitive | Verb | Purpose |
|-----------|------|---------|
| **Judge** | J | Initiate an observation assertion |
| **Delegate** | D | Transfer authority to another agent |
| **Terminate** | T | Close the lifecycle of a prior assertion |
| **Verify** | V | Cross-validate an existing assertion |

## Complete Cognitive Interaction Algebra

These four primitives form a complete algebra:
- **J** creates state.
- **V** validates state.
- **D** distributes responsibility for state.
- **T** invalidates state.

Any complex multi-agent collaboration decomposes into ordered combinations of these four atoms. No fifth primitive is required.

## Protocol Alignment

All events produced are strict JEP-04 compliant:
- `jep`: "1"
- `verb`: J/D/T/V
- `who`: issuer DID
- `when`: Unix timestamp
- `what`: SHA-256 multihash of payload
- `nonce`: UUIDv4
- `aud`: target
- `ref`: chain link
- `sig`: JWS signature
- `task_based_on`: JAC-01 parent task hash

## Integration

Events feed directly into:
- **Determinability-Checker** — causal sufficiency verification
- **COE-Consensus** — shared world state formation
- **JEP-Guard-Audit** — compliance chain generation
