| L0 INVARIANT ENFORCEMENT | |
| ================================================================================ | |
| All 5 L0 invariants from Ada kernel enforced at L2 boundary: | |
| OK 1. Plasma Gate (Ed25519 Signature) | |
| Enforced by: seb_kernel_nif:append_event/4 | |
| Pre-condition: Ed25519.Verify | |
| OK 2. Hash Chain Validity | |
| Enforced by: seb_kernel_nif:append_event/4 | |
| Pre-condition: prev_hash == current_tip_hash | |
| OK 3. Offset Monotonicity | |
| Enforced by: seb_agent_fsm + seb_kernel_nif | |
| Invariant: offset > prior_offset | |
| OK 4. Payload Hash Verification | |
| Enforced by: seb_kernel_nif:append_event/4 | |
| Pre-condition: blake3(header || payload) == footer.event_hash | |
| OK 5. Segment Chain Linking | |
| Enforced by: seb_kernel_nif:verify_chain/0 | |
| Pre-condition: prev_seg_hash links to prior segment | |
| ================================================================================ | |
| SUCCESS CRITERIA - ALL MET | |
| ================================================================================ | |

| - draining state: reject new, process queue | |
| - checkpointed state: offset committed | |
| - stopped state: final cleanup | |
| - Drain timeout: 30 seconds (hardcoded) | |
| OK Partition Assignment Deterministic | |
| - Count: 1024 (fixed) | |
| - Algorithm: phash2({agent_id, competency}) mod 1024 | |
| - Same seed = Same result verified | |
