FIX7 Final Recommendation - Corrected

Corrected architecture uses sealed typed manifest-driven generic interpreters; no authoritative mechanism code branches on gate, tier, capability, collection, vector, or hash-component identity. Manifest activation requires independent exact quorum/fresh evidence. Runtime roles have zero direct target DML. Writer/activation use hash-bound control epoch.

T1 may author/test FIX7a/b/c and may live-deploy FIX7a only through operator-gated approved pipeline while authority_cutover_complete=false. Roles, ownership, ACL, activation, scheduler, and repoint remain operator-gated. Codex remains independent reviewer. Stage 2.6B remains blocked.
