Check C - doc 00 Self-Reference

Verdict: DOC00_SELF_REFERENCE_RESOLVED

T1 selected one consistent model: normalized_active_content_sha256 is the sole load-bearing per-document hash; doc 00 removes the explicit ENVELOPE:EXCLUDE region; full_document_sha256 is non-authority diagnostic for every member. The envelope is intended to be protected by a detached seal rather than doc 00's own hash.

This resolves the doc 00 self-hash loop. Final approval remains blocked by the separate active-scope extraction and detached-seal circular-anchor defects.
