# Ninth independent audit closure — 2026-08-26

## Truth state

**BLOCKED / NO-GO.** `partnerReady=false`, `pilotReady=false`, V2 remains the
default, and there are zero active design partners. No human identity, external
authority, legal entity, contact, signature, acceptance, insurance, audit,
deployment, wallet action, RPC action, or partner fact was invented.

A separate randomness-beacon trust policy is deliberately disabled and unpinned.
Consequently, even otherwise complete unlinkability evidence cannot support a
positive readiness result until a later reviewed exact-source commit pins a
genuine independent authority.

## Finding closures

- **H-01 — closed in source, positive state still blocked.** The v1
  caller-labelled output contract was removed. Protocol v2 takes only an
  exact-candidate context and content-addressed corpus. It derives candidate
  outputs, expected/observed relationships, complete event coverage, and every
  row digest. The readiness checker repeats the derivation independently and
  requires byte-for-byte equality. Caller outcomes, output digests, arbitrary
  pair IDs, reversed pairs, and partial corpus results are rejected.
- **M-01 — closed in source, external authority intentionally absent.** The seed
  is exactly 32 bytes and must equal a separately resolved, Ed25519-signed public
  randomness receipt from a source-commit-pinned authority. Its domain-separated
  commitment binds candidate ID, source commit/tree, evidence commit/tree,
  scope, runner, corpus, evaluation context, beacon authority/round, and opening
  digest. The signed beacon must postdate the immutable evidence commit. Public
  deterministic byte sequences are expressly rejected. Content IDs and pair IDs
  are recomputed; unordered duplicates fail.
- **M-02 — closed.** Opaque incident bytes were replaced by five closed event
  schemas: detection, triage, escalation, containment, and partner notification.
  The checker validates objective-specific participants, channels, actions,
  ordered timestamps, derived event/assertion IDs, and an assigned participant's
  Ed25519 controller receipt.
- **L-01 — closed.** The standalone runner applies lowercase 64-hex validation to
  every SHA-256 field, 40-hex validation to Git object IDs, and verifies the
  declared runner digest against its own executing bytes. It accepts no
  `runnerOutputSha256` input.

## Regression and validation results

- Normal suite: **198/198 passed**.
- Python `-O` suite: **198/198 passed**.
- Ninth-generation named regressions: **15/15 passed**, including all eight
  accepted ninth-audit symptoms and seven additional mutations.
- One-sided Hoeffding oracle: **20,000/20,000 matched**, zero mismatches.
- Strict JSON parse: **59 files passed** before this closure record; **60 JSON
  files** including this closure JSON.
- Python AST parse: **15/15 passed**.
- Package and blocked organizational gates: **two runs each, deterministic**.
- Package gate truth: pilot false, organizational partner readiness false, V2
  default true, zero partners.
- Organizational gate truth: blocked, 25 mandatory evidence items open, 14
  external human blockers open.
- Cache gate: zero `__pycache__`, `.pyc`, or `.pyo` artifacts.
- Original through eighth relevant harnesses executed. Original 16/16, fourth
  33/33, fifth 37/37, and eighth 29/29 retained secure outcomes. Sixth retained
  54 secure outcomes with five stale positive fixtures rejected. The unmodified
  ninth harness reports 48/59 under its historical expectations because eleven
  cases intentionally invert after remediation (five former accepted runner
  bypasses and the opaque incident schema now reject) or use obsolete internal
  source heuristics; the authoritative named v2 regressions are 15/15.
- No install, commit, push, deployment, signing, wallet, or RPC action occurred.

The package contains 108 files including these two closure records, 60 JSON
files, and 15 Python files.

## Remaining external blockers

The 14 mandatory human blockers remain open: actual contacts, authorized
signatory, change-RACI acceptance, commercial agreement, counsel signoff,
incident-plan acceptance, insurance, legal entity, partner acceptance, privacy
signoff, role assignments, security-policy acceptance, signatures, and support
SLA selection. In addition, genuine independently administered human-identity,
legal-registry, and randomness-beacon trust roots must be reviewed and pinned;
a clean exact-candidate/evidence/attestation history and all objective evidence
must be provided. None is claimed here.
