## I. Banner & Hook

`VAULT999` is the persistent memory layer of arifOS. It stores the immutable audit trails of every session, verdict, and tool call. Using cryptographic Merkle chaining, it ensures that the history of the intelligence kernel is verifiable and tamper-proof.

---

## II. Mnemonic & Banding (L2 Memory)

In the 4-layer taxonomy, `VAULT999` operates within the **L2 Operation** layer as the "Memory" component of the 7-Organ Sovereign Stack.

| State | Role | Location |
| :---: | :--- | :--- |
| **Hot** | Current Session | Redis / Memory |
| **Warm** | Recent Ledger | SQLite (`vault_sqlite.py`) |
| **Cold** | Permanent Audit | PostgreSQL (`VAULT999/`) |

## III. Architecture Map (Merkle Chaining)

The vault uses a "Sealed Ledger" approach:
```text
PREVIOUS_HASH ➔ CURRENT_ACTION ➔ VERDICT ➔ NEXT_HASH (Merkle Root)
```

**Components:**
- **`vault_sqlite.py`**: The local edge-memory implementation.
- **`vault_postgres.py`**: The production-grade immutable storage.
- **`migration/`**: Tools for moving between SQLite and Postgres.

---

## IV. Operational Interface (Vault Commands)

- **`seal(session_id, data)`**: Commits a verdict to the ledger.
- **`verify_chain()`**: Runs a cryptographic audit of the entire vault.
- **`purge()`**: Highly privileged command to archive data (Human Sovereign Only).

---

## V. Constitutional Alignment (Amanah)

- **F1 Amanah**: Guaranteed auditability and reversibility.
- **F3 Tri-Witness**: Ledger entries require consensus signatures.
- **F8 Genius**: Stores metadata on session efficiency and performance.

---

## VI. Quick Start & Deployment

### Run a Vault Audit
```bash
python arifosmcp.transport/vault_sqlite.py verify
```

### Production Setup
Ensure PostgreSQL is configured according to the `DATABASE_URL` in your environment.
