# Fourth independent audit remediation closure

**Package state:** blocked; `partnerReady: false`.

This is an engineering remediation record, not legal advice, an audit opinion,
partner acceptance, deployment evidence, entity formation, or a signature.

## Finding-by-finding closure

### H-01 — phase-two fixed point

Closed in the validator and regressions.

- The candidate ID preimage excludes commits, trees, evidence, signatures, and
  candidate-bound artifacts.
- Phase two is one direct-child evidence commit. No phase-two artifact fact may
  contain the evidence commit/tree or artifact-manifest digest.
- The artifact manifest lists phase-two blobs but not itself.
- Phase three computes the envelope only after phase two exists. The final
  direct-child commit adds only the post-commit envelope/manifest.
- The envelope binds candidate ID, source commit/tree, evidence commit/tree,
  and artifact-manifest digest; it does not bind its own phase-three commit.
- Exact parents, exact phase diff path sets, clean HEAD, and tracked bytes are
  enforced. A temporary isolated Git fixture proves finite construction.

### H-02 — assertion-shaped artifacts

Closed for the audited bypasses and critical resolved records.

- Exact test-result objects require a nonempty test array, strict Boolean
  `passed: true`, positive assertion counts, zero failures, exact suite,
  candidate, source commit, tree, scope, and log-digest bindings.
- Dedicated exact schemas and semantic resolvers cover artifact manifests,
  test results, signature sets, bounded liabilities, privacy portability,
  executed commercial agreements, and controlled contact matrices.
- Canonical operations is validated against its canonical release-status
  schema and completion predicates.
- Every resolved artifact is a unique normalized repository path, a unique
  digest, tracked at the evidence commit, byte-identical to that commit, and
  reconciled into one phase-two artifact manifest.

### H-03 — weak signature set

Closed in the signature-set and post-commit envelope verifiers.

- The required organization set is exactly the manifest subject and partner
  organizations.
- The required signer set is derived from the four exact assigned roles:
  release manager, independent reviewer, authorized signatory, and partner
  authorized signatory.
- Identity, organization, role, Ed25519 key digest, authority evidence,
  authority chain, payload digest, four-of-four threshold, signer uniqueness,
  signature uniqueness, and detached signatures are checked exactly.
- Missing, extra, substituted, wrong-role, wrong-key, or cross-organization
  signers fail closed.

### L-01 — stale cache regression

Closed.

- The normal package must contain no `__pycache__`, `.pyc`, or `.pyo` entries.
- The package gate rejects an injected cache entry.
- The regression now tests absence first and rejection only after controlled
  injection.

## Regression coverage

- All 33 named fourth-generation harness cases are represented in
  `tests/test_fourth_generation_audit.py`.
- The nine demonstrated gaps are covered: phase-two fixed point; six arbitrary
  semantic blobs; weak exact-commit tests; and weak signature set.
- Cache absence/injection is covered separately in
  `tests/test_partner_package.py`.
- The staged-Git positive fixture creates source, evidence, and attestation
  commits only inside a temporary isolated repository.

## Verification results

| Check | Result |
|---|---|
| Full tests, normal Python | PASS — 119/119 |
| Full tests, `python -O` | PASS — 119/119 |
| Independent fourth harness logic | PASS — 33 secure, 0 insecure |
| Python syntax | PASS — 9 files |
| Strict JSON parse / duplicate-key rejection check | PASS — 31 files |
| Package fail-closed gate | PASS |
| Deterministic blocked report | PASS |
| Blocked report SHA-256 | `b783b18c99d20521ef410e82633bfc9d9c7d3fa9752db3e4d752531c72920cf6` |
| Cache/generated-file count | 0 |
| Scoped `git diff --check` | PASS |

No package installation, real repository commit, push, deployment, RPC,
wallet, or signing action was performed.

## Remaining external blockers

Positive readiness remains structurally disabled by the pinned
`no-external-authority-established` trust policy. A later reviewed commit must
pin a real independent authority before any ready path can succeed.

The 14 external-human blockers remain open and unfilled:

1. `LEGAL-ENTITY`
2. `AUTHORIZED-SIGNATORY`
3. `ACTUAL-CONTACTS`
4. `INSURANCE`
5. `COUNSEL-SIGNOFF`
6. `PRIVACY-SIGNOFF`
7. `PARTNER-ACCEPTANCE`
8. `ROLE-ASSIGNMENTS`
9. `COMMERCIAL-AGREEMENT`
10. `SIGNATURES`
11. `SECURITY-POLICY-ACCEPTANCE`
12. `INCIDENT-PLAN-ACCEPTANCE`
13. `SUPPORT-SLA-SELECTION`
14. `CHANGE-RACI-ACCEPTANCE`

All 25 mandatory readiness claims remain open in the truthful template.
