## Method

I followed the H33 Independent Verification Guide v1.0 (`/proofs/independent-verification-kit/VERIFICATION-GUIDE.md`). I performed the steps below independently, without H33's assistance during execution.

## Step-by-step findings

### Step 1 — Fetch the bundle

- [ ] `bundle_id` matched expected value (`d9adcfb0-…`)
- [ ] `schema` matched (`v101-bundle-v1.1`)
- [ ] `creator_uuid` matched (`44962d9b-…`)
- [ ] `h33_74_receipt.status` was `anchored`
- [ ] `anchor_ref.chain` was `h33-substrate-v1`
- [ ] `tx_reference` was 148 hex chars
- [ ] `commitment_hex` was first 64 hex chars of `tx_reference`

_Result:_ _PASS / FAIL / PARTIAL — describe._

### Step 2 — Verify the SHA3-256 commitment

- [ ] Recomputed SHA3-256 of the canonical JSON
- [ ] Matched expected `ff770fc838fde707d91f35248946d6928b0a3a999dbd28a2906ce4f0274745e7`

_Result:_ _PASS / FAIL — describe._

### Step 3 — Verify Auth1 published the EdDSA public key

- [ ] JWKS at `https://auth.h33.ai/.well-known/jwks.json` contained `kid-eddsa-prod-active-2026-06-01-d31134fbc177`
- [ ] `kty` was `OKP`, `crv` was `Ed25519`, `alg` was `EdDSA`

_Result:_ _PASS / FAIL — describe._

### Step 4 (optional) — Verify a fresh Bearer's signature

_Did you perform this step?_ _Yes / No_

If yes:

- [ ] `alg = EdDSA`
- [ ] `iss = https://auth.h33.ai`
- [ ] `aud` was a published receipt-issuing audience
- [ ] Signature verified against JWKS public key

_Result:_ _PASS / FAIL / SKIPPED — describe._

### Step 5 — Verify the 74-byte H33-74 receipt decomposition

- [ ] `tx_reference` decomposed cleanly into `signing_message ‖ CompactReceipt`
- [ ] `version` byte was `0x01`
- [ ] `algorithm_flag` was `0x07` (all three families)
- [ ] `verified_at_ms` was within issuance window

_Result:_ _PASS / FAIL / PARTIAL — describe._

_Note:_ Per the guide, raw PQ signatures are summarized into the verification_hash; direct signature verification requires the `h33-verifier` binary (roadmap item #8).

### Step 6 — Regulator Replay determinism

_Did H33 provide read access to `canonical_auth_events`?_ _Yes / No_

If yes:

- [ ] Ran the harness at scif-backend SHA `d310d8134`
- [ ] Captured `state_id`: _______________
- [ ] Matched expected `96a29047010a201dfa2a5254897a664ee2c20b9ac437406f61609f7144beae4a`

_Result:_ _PASS / FAIL / SKIPPED — describe._

### Step 7 — Multi-Tenant Isolation

If yes:

- [ ] Captured `state_id(A)`: _______________
- [ ] Captured `state_id(B)`: _______________
- [ ] Injection verdict was `ProvenanceBroken`, `active_grants = 0`

_Result:_ _PASS / FAIL / SKIPPED — describe._

## Findings

### Confirmed claims

_List every claim verified end-to-end._

### Gaps observed

_List every claim that could not be verified (e.g., raw PQ signatures, source code, scale)._

### Issues

_List every value mismatch, every failed assertion, every concern._

---

## Overall assessment

_Choose one and explain in 2-4 sentences:_

- **Confirmed.** Every verified claim matched the expected value.
- **Confirmed with gaps.** Most claims verified; some required additional access H33 has not yet published.
- **Partial.** Some claims confirmed, some required follow-up.
- **Not confirmed.** Material divergences observed; described above.
