Boundary

Additive child of PR #380. No merge, no training, no old Corpus370 changes. Source candidates are not automatically independent characters or head truth.

Content

• Per-head minimum 1000 FIT distinct identity clusters with separate CORE supervision versus FULL optional IK/graphics coverage, exact source SHA, six independent court receipts, commercial ML rights and split-firewall checks.
• External source scouting registry including Blender Studio production rig candidates, Mesh2Motion CC0 native control rigs, large Objaverse/Articulation candidates with explicit overlap/licensing/no-AI source restrictions.
• Native .blend source pilot using immutable upstream commit and --disable-autoexec, with exact transported-source and decoded Blender SHA where upstream .blend is ZSTD wrapped.
• Source/presentation/semantic/control proof responsibilities remain typed and unqualified without real courts.

Measured

• Private Master 3993 typed-source mapping and zero qualified head admission validated in run 42382498716.
• Original Mesh2Motion native snake/spider/dragon control pilot successful run 42384239311: snake 38 bones, 23 non-IK constraints; spider 75 bones, 8 IK; dragon 165 bones, 6 IK, 42 drivers. Native IK functionality not yet proven. Dragon imported driver warnings require independent runtime court.

Quarantine external native source previews; source-bound control perturbation court; license receipts; don't overcount same rig or different animation clips as subjects.
