| ## النطاق | Scope | |
| **المرحلة 5: التحقق الرسمي + ختم WORM** | |
| **Phase 5: Formal Verification + WORM Sealing** | |
| This phase completes the syscall OS by: | |
| - Documenting formal verification requirements | |
| - Specifying Blake3 integration for trust/WORM | |
| - Integration testing checklist | |
| - Production deployment guide | |
| **Note:** Actual Lean 4 proofs and Blake3 library integration | |
| are left as future work (requires kernel build environment). | |

| ## التحقق الرسمي | Formal Verification | |
| ### Verification Targets | أهداف التحقق | |
| 1. **Intent Schema Correctness** | |
| - [ ] SystemIntent struct layout matches Haskell Intent type | |
| - [ ] IntentResult struct layout matches Haskell PolicyDecision | |
| - [ ] No padding mismatches (alignment violations) | |
| 2. **Ring Buffer Safety** | |
| - [ ] No race conditions (SPSC lock-free correctness) | |
| - [ ] Memory barriers enforce visibility | |
| - [ ] Wraparound arithmetic correct (mask = capacity - 1) | |
| - [ ] No buffer overflows | |
| 3. **Policy Engine Soundness** | |
| - [ ] Resource allocation never exceeds system limits | |
| - [ ] Priority enforcement monotonic (CRITICAL > HIGH > NORMAL > BG) | |
| - [ ] Error recovery terminates (no infinite loops) | |
| - [ ] Trust verification rejects invalid nonces | |
| 4. **FFI Marshalling Correctness** | |
| - [ ] `marshalIntent` preserves all fields | |
| - [ ] `unmarshalDecision` writes valid C structs | |
| - [ ] Null pointer handling safe | |

| hash ^= intent->priority; | |
| ``` | |
| **Phase 5 (libblake3):** | |
| ```c | |
| #include <blake3.h> | |
| static void generate_trust_nonce(const struct SystemIntent *intent, | |
| uint8_t *nonce_out) | |
| { | |
| blake3_hasher hasher; | |
| blake3_hasher_init(&hasher); | |
| /* Hash intent fields */ | |
| blake3_hasher_update(&hasher, &intent->intent_type, 4); | |
| blake3_hasher_update(&hasher, &intent->priority, 4); | |
| blake3_hasher_update(&hasher, intent->goal_schema, | |
| strlen(intent->goal_schema)); | |
| blake3_hasher_update(&hasher, &intent->timestamp_ns, 8); | |
| /* Finalize */ | |
| blake3_hasher_finalize(&hasher, nonce_out, 32); | |
| } | |
| ``` | |
| ### WORM Seal (Phase 5 Complete) | |
| **Kernel (ring_buffer_complete):** | |
| ```c | |
| /* Compute WORM seal: Blake3(intent || result || timestamp) */ | |
| blake3_hasher hasher; | |
| blake3_hasher_init(&hasher); | |
| blake3_hasher_update(&hasher, &entry->intent, sizeof(entry->intent)); | |
| blake3_hasher_update(&hasher, &result, sizeof(result)); | |
| uint64_t seal_timestamp = ktime_get_ns(); | |
| blake3_hasher_update(&hasher, &seal_timestamp, 8); | |
| blake3_hasher_finalize(&hasher, result.worm_seal, 32); | |
| ``` | |
| **Haskell (TrustVerifier.hs):** | |
| ```haskell | |
| import Crypto.Hash.Blake3 (hash) | |
| computeExpectedNonce :: Intent -> BS.ByteString | |
| computeExpectedNonce intent = | |
| let payload = encodeIntent intent -- Binary encoding | |
| in hash payload -- Blake3 hash | |
| ``` | |

| ### Integration Test Plan | خطة اختبار التكامل | |
| **Test 1: End-to-End Intent Flow** | |
| ```bash | |
| # 1. Load kernel module | |
| sudo insmod kernel-module/asos_kar.ko | |
| # 2. Run hello_asos | |
| ./userspace/examples/hello_asos | |
| # 3. Check dmesg | |
| dmesg | grep "KAR Dispatcher" | |
| # Expected: | |
| # KAR Dispatcher: received intent type=7 priority=1 from PID=1234 | |
| # KAR Worker 0: processing intent type=7 agent=5 | |
| ``` | |
| **Test 2: WORM Write Verification** | |
| ```bash | |
| # 1. Run write_worm example | |
| ./userspace/examples/write_worm | |
| # 2. Verify WORM seal | |
| # Expected: 32-byte Blake3 hash printed | |
| # 3. Replay attack test (submit same intent twice) | |
| # Expected: Second submission rejected (trust nonce fail) | |
| ``` | |
| **Test 3: Priority Preemption** | |
| ```bash | |
| # 1. Submit 100 BACKGROUND intents | |
| # 2. Submit 1 CRITICAL intent | |
| # 3. Verify CRITICAL processed first | |
| # Expected: Worker 0 processes CRITICAL immediately | |
| ``` | |
