# Post-execution CLEAN attestation (sanitized)

_Source: CrewOS commit `93255817` (attestation) and the FoundryOS post-exec attestation record. No
client data; internal-only implementation shas generalized._

After the source conditions were made resolvable, the authoritative post-execution audit ran and
reached CLEAN.

- **Attestation commit:** `93255817` — "authoritative CLEAN post-exec attestation — epp-designation-clear".
- **Transport:** the Codex review bus. **Test gate:** PASS (full suite green in an isolated checkout of
  the pinned tree).
- **Two-cycle audit:**
  - *Cycle 0* returned one **major** finding — a grant-addressed clear could bypass the expected-holder
    compare when a participant reference was null. It was **folded as a class** (not a one-off patch).
  - *Cycle 1* returned **CLEAN, 0 findings.**
- **Gate overrides:** recorded in both cycles, both on **plan-artifact** gates (a fleet-wide schema
  convention change), **never on a code gate.** The overrides are logged, not silent.

This is the separate-audit half of the build: the implementing context did not certify itself. A
role-, context-, and source-separated audit ran against the pinned tree, surfaced a real major finding,
required it to be folded as a class, and only then reached a clean terminal state.

_Independent pre-merge review also ran on the un-designation change (`d20a60ea`): an adversarial cold
review returned 5 findings, all folded (1 medium, 4 low). The medium: a wrong-participant guard that
lived only in a UI render condition was moved into the database layer — the correct place for an
authorization boundary._
