|
| ## Architecture |
|
|
| The L4 adapters implement WORM-sealed settlement routing on IBM mainframes: |
|
|
| ``` |
| ┌─────────────────────────────────────────────┐ |
| │ Codestorm Hub (RPC Client) │ |
| └──────────────────┬──────────────────────────┘ |
| │ |
| ▼ |
| ┌──────────────────────┐ |
| │ SEB_Fiscal_Settlement│ |
| │ (RPG/ILE Entry) │ |
| └──────────────────────┘ |
| │ |
| ┌──────────┼──────────┐ |
| ▼ ▼ ▼ |
| ┌────────┐ ┌──────┐ ┌─────────┐ |
| │Validate│ │SEB │ │SOVEREIGN│ |
| │Bifrost │ │Append│ │LEDGER │ |
| │Hash │ │Event │ │Insert │ |
| └────────┘ └──────┘ └─────────┘ |
| │ │ │ |
| └──────────┼──────────┘ |
| │ |
| ▼ |
| ┌──────────────────────┐ |
| │ SEB_Settlement_Error │ |
| │ (Error Handler) │ |
| └──────────────────────┘ |
| │ |
| ▼ |
| ┌──────────────────────┐ |
| │ WORM Chain │ |
| │ (Immutable Log) │ |
| └──────────────────────┘ |
| ``` |
|
|
| **Flow**: |
| 1. RPC request → SEB_Fiscal_Settlement |
| 2. Validate Bifrost_Hash for idempotency |
| 3. Append event to SEB chain (Blake3+Ed25519 seal) |
| 4. Insert into SOVEREIGN_LEDGER (DB2) |
| 5. Emit confirmation event |
| 6. Call SEB_Kernel_Append_Event NIF |
| 7. Return settlement ID (offset) |
| |
| --- |
| |
| ## Guarantees |
| |
| ### Idempotency |
| |
| The settlement adapter guarantees exactly-once semantics via Bifrost_Hash deduplication: |
|
|
| ``` |
| First call: → New settlement, insert into ledger, return offset |
| Retry call: → Same Bifrost_Hash, return existing offset |
| No duplicate: → ACID compliance, settlement counted once |
| ``` |
|
|
| ### Crash Recovery |
|
|
| Even if the process is killed with `SIGKILL (-9)` during append: |
|
|
| ``` |
| SEB chain: Remains valid (WORM integrity preserved) |
| SOVEREIGN_LEDGER: Atomic (all-or-nothing insert) |
| Recovery: Next call detects duplicate hash, returns offset |
| Audit: All events verifiable via cryptographic seals |
| ``` |
|
|
| ### Cryptographic Sealing |
|
|
| Every event is Blake3+Ed25519 sealed: |
|
|
| ``` |
| Event Envelope: |
| ┌─────────────────────────────────────┐ |
| │ Header (68 bytes) │ |
| │ - Offset, Timestamp, Agent_ID │ |
| │ - Event_Type, Payload_Size, Reserved│ |
| ├─────────────────────────────────────┤ |
| │ Footer (128 bytes) │ |
| │ - Prev_Hash (Blake3 hex, 64 bytes) │ |
| │ - Event_Hash (Blake3 hex, 64 bytes) │ |
| │ - Signature (Ed25519 hex, 128 bytes)│ |
| ├─────────────────────────────────────┤ |
| │ Payload (variable) │ |
| │ - JSON structured data │ |
| │ - Stored in separate BLOB file │ |
| └─────────────────────────────────────┘ |
| ``` |

| |
| ## Next Phase: VERIFICATION (G4 Gate) |
| |
| Upon successful compilation and chaos testing, the VERIFICATION agent will: |
| |
| 1. **Formal Proof**: Prove crash recovery properties in Lean 4 |
| - Theorem 1: Chain integrity preserved after kill -9 |
| - Theorem 2: Idempotency enforced by Bifrost_Hash |
| - Theorem 3: No race conditions in concurrent appends |
|
|
| 2. **Verification Artifacts**: |
| - `SEB_L4_Chaos_Proofs.lean` — Formal proofs (0 sorry) |
| - Verification report with signatures |
| - Integration with Phase 3 loop invariants |
|
|
| 3. **Handoff to INTEGRATION**: |
| - Wire fiscal adapter into Bifrost middleware |
| - End-to-end settlement testing |
| - Production deployment |
