PHASE2 SUBSTRATE MEMORY CONTRACT

Phase 2 — Substrate Memory Contract¶

Purpose¶

Substrate is the durable memory cortex of Mobius.

Terminal is the pulse. Substrate is memory. Civic Protocol Core is proof.

Substrate Responsibilities¶

Substrate receives broad but valid memory:

AGENT_JOURNAL_V1
MESH_STATE_V1
MESH_HEALTH_V1
MESH_TODOS_V1
HIVE_WORLD_PULSE_V1
WORLD_UPDATE_V1

Substrate stores:

journals/{cycle}/{agent}.jsonl
ledger/mesh-aggregate.json
ledger/mesh-todos.json
ledger/mobius-pulse.json

Substrate forwards only proof-worthy events to Civic Ledger:

EPICON_ENTRY_V1
MIC_READINESS_V1
MIC_SEAL_V1
MESH_STATE_V1
WORLD_UPDATE_V1

Retention¶

The Terminal should not become storage.

HOT window: Terminal/KV rolling memory
Substrate: append-valid durable memory
Civic Ledger: proof-worthy attestations

Idempotency¶

Substrate memory packets should include:

node_id
event_type
cycle
source_hash
workflow_id

These fields prevent repeated workflow pulses from becoming duplicate memory.

Canon¶

Substrate may remember noisy but valid agent journals. Civic Ledger proves selectively. Terminal remains the operator view.

We heal as we walk.
