Check F - Codex Sealing Execution

Verdict: CODEX_SEALING_NEEDS_T1_FIX

Executed independently:

• active_corpus_membership_sha256 over the ten full canonical document paths under FIX7_ACTIVE_AUTHORITY_MEMBERSHIP_V1 = f2bda8effc7be19b54722828126b82d7d2d48bee5e5e5dc0c8f347ce210fe251 — verified.
• Current active revisions were read back through MCP: 00=18, 01=6, 02=33, 03=6, 04=39, 05=24, 06=58, 07=47, 08=17, 12=43.

Not sealed because load-bearing computations remain ambiguous/circular:

• per-doc normalized active content hashes;
• active corpus hash;
• marker/fence registry hash;
• superseded boundary hash;
• guard-set hash contract;
• complete envelope manifest hash;
• detached seal hash/checkpoint content hash.

No placeholder or partial seal was authored.
