Check D - No-Disposition Envelope Scope Recheck

Verdict: NO_DISPOSITION_ENVELOPE_SCOPE_NEEDS_FIX

T1 correctly rebound G-LEGACY-NO-DISPOSITION-AUTHORITY to a SEALED envelope and retained report-only handling for fenced history. No active disposition/STUB model was found under another name.

This check remains blocked downstream because no valid complete envelope can yet be sealed. After the canonicalization/self-reference/anchor fixes, the guard must depend on the exact sealed envelope and fail on absent, unsealed, unknown-field, hash-mismatched, or anchor-mismatched envelopes.
