# Eleventh Independent Audit Remediation Closure

**Date:** 2026-08-26  
**Scope:** `pr10/partner-package` only  
**Truth state:** `partnerReady=false`, `pilotReady=false`, V2 remains the default, and active design partners remain zero.

This record documents implemented controls and local verification. It is not an audit opinion, legal advice, partner acceptance, a signature, a deployment record, or evidence that any external authority has been established.

## Finding-by-finding closure

### C — Candidate-controlled adapter and oracle

**Closed in the package gate.**

- The public runner no longer accepts a candidate-adapter path or an oracle selected by the caller.
- The package policy fixes one canonical repository-relative implementation path, semantic interface identifier, and independent oracle identifier.
- Positive verification requires the canonical path to resolve to the exact Git blob at the source commit.
- The candidate receives blinded request identifiers and input bytes. Its closed response schema contains only the request identifier and raw portability output.
- Output digests, relationships, coverage, privacy predicates, and pass/fail are recomputed by the independent runner/checker; candidate-declared predicates are prohibited.
- Alternate paths, path aliases, symlinks, and hardlinks fail closed.

### H-01 — Hermetic isolation and exact toolchain

**Closed for the local positive fixture; structurally blocked for real readiness.**

- The positive fixture uses Linux namespace isolation with no network, an empty environment allowlist, explicit read-only file mounts, an empty executable search path, bounded time and resource limits, and a child-process limit.
- The exact Python binary, version, binary digest, standard-library tree digest, dynamic-library identities, sandbox launcher, and launcher digest are bound into the execution record.
- Escape probes for network, unauthorized filesystem reads, and child-process creation are denied.
- The tracked real-package execution trust policy is intentionally disabled because no genuine externally reviewed candidate implementation, toolchain, execution signer, or authority is pinned. Positive partner readiness therefore remains structurally impossible.

### H-02 — Atomic execution evidence

**Closed in the staged execution architecture.**

- The runner generates, rather than accepts, exact launcher/candidate argv, UTC and monotonic timing, exit status, stdout/stderr bytes and digests, request/response/event digests, execution nonce, and toolchain identities.
- Raw events and the execution record are written with staged files, `fsync`, and atomic replacement.
- A machine Ed25519 receipt signs the completed record preimage, and the checker verifies it against the policy-pinned key.
- The source, randomness/selection, execution-evidence, and post-commit attestation stages remain finite and acyclic; no artifact embeds its own commit, tree, or digest.

### M — Incident timing and role/channel evidence

**Closed in the checker.**

- Escalation send start, containment action start, partner-notification send start, signed receipts, assertions, and objective completion must all fall within the candidate execution interval.
- Each objective has strict event ordering, bounded future skew, freshness, receipt-to-completion bounds, and unique nonces.
- Participants, controllers, organizations, assigned roles, objective-specific contact channels, and receipts remain cross-bound to the typed evidence model.

### L — Noncanonical paths

**Closed.**

- The implementation path is an exact policy constant, not caller-controlled.
- Repository containment, normalized path equality, exact Git object identity, and canonical file identity are required.
- Symlinks, path traversal, aliases, alternate in-repository implementations, and multi-linked files are rejected.

## Regression and verification results

- Eleventh-generation named hostile probes: **18/18 passed**.
- Complete normal suite: **278/278 passed**.
- Complete optimized suite (`python -O`): **278/278 passed**.
- Hermetic positive fixture: **passed** on the current Linux environment.
- Strict dependency-free Draft 2020-12 subset: **41/41 package schemas passed**.
- Strict JSON duplicate-key/non-finite-number parsing: **73/73 tested package JSON documents passed** (the generated strict-check result excludes itself).
- Organizational gate: deterministic and blocked.
- Package validator: deterministic and blocked.
- Cache/generated-file gate: no `__pycache__` or `.pyc` files; injected cache content is rejected.
- Path hygiene: no package symlinks or multiply linked regular files.
- Original eleventh exploit harness: halted at its first legacy caller-selected adapter attempt with the expected fail-closed error. The 18 attacks are reproduced as named internal regressions rather than weakening the new API to let the obsolete harness continue.

## Remaining blockers

### External human blockers (14)

1. Actual contacts
2. Authorized signatory
3. Change-RACI acceptance
4. Commercial agreement
5. Counsel signoff
6. Incident-plan acceptance
7. Insurance
8. Legal entity
9. Partner acceptance
10. Privacy signoff
11. Role assignments
12. Security-policy acceptance
13. Signatures
14. Support/SLA selection

### Other mandatory evidence blockers (11)

1. Bounded liabilities
2. Candidate binding
3. Canonical operations
4. Exact-commit tests
5. Fail-closed APIs
6. Immutable evidence
7. Module rollout
8. Pause-safe exits
9. Privacy-preserving cross-chain portability
10. Protected-decision input controls
11. Pull payments

### Additional structural authority blockers

- No genuine external human-identity authority is pinned.
- No genuine legal-entity registry authority is pinned.
- No genuine randomness authority chain is pinned.
- No genuine privacy-execution authority, canonical implementation, exact production toolchain, or execution signer is pinned.
- No candidate-bound, typed, unique, tracked evidence set or completed finite freeze/attestation history exists.

Until a later reviewed commit pins genuine independent authorities and supplies all mandatory candidate-bound evidence, every positive readiness claim must fail closed.
