5. Verdict

Overall independent verdict: ENGINEERING_UMBRELLA_PASS_BOUNDED

Bound identities confirmed live? NOT RE-VERIFIED this session (evidence bound to listed SHAs)

Production authorized? NO

CERTIFIED (production baseline)? NO

Explicit non-claims:

  • Not production authorization
  • Not full QG-18 CERTIFIED label
  • Optional waves without harness remain NOT RUN / BLOCKED in matrix until wave harness passes
  • Independent human auditor signature still required for formal QG-18 upgrade

Narrative:

Engineering evidence for Phases 0–3 is sufficient for a bounded umbrella pass at the documented FE/BE tip: Golden Tenant reproducibility, navigation/containment gates, and re-cert harnesses for W05/W11/FFBR are on record. GREY workflows W08/W17/W18 are fail-closed. This verdict unblocks Phase 4 engineering per owner prompt authorization; it does not certify production or the full ~198 RT matrix.
