Exact runtime members
| Set/profile | Role or coordinate | Exact members | Variant/type | Timing or motion | Runtime contract |
|---|---|---|---|---|---|
hypothesis/full-body-unarmed-to-pistol | source-state | mixamo-basic-locomotion::Basic_Locomotion_Pack_-_in-place/walking.fbx | set_type=transition-chain | duration=1.033 s; frames=32 frames | loop=unknown; transition=full-body; movement=controller-xz-yaw; state=unarmed |

The table above preserves the measured member detail from the companion report; its proposed controller still requires target-engine acceptance.

The 231 metadata motion count is not mapped to the 249 files. Exact current paths remain opaque canonical units. New hypotheses use only named current files and do not claim vendor intent or recovered historical membership. All nine spreads use normalized circular range, defined as 1 - largest cyclic gap across member phases on the unit cycle; a spread alone establishes neither support-foot compatibility nor a source defect.
Mechanical baseline
| Finding/check | Affected scope | Potential impact | Evidence |
|---|---|---|---|
| No baseline errors | 249/249 files | File-readable prerequisite only | Current ledger |
duration-sanity | 50 findings | Empty reference takes or endpoint clamp-hold | Exact paths in constituent appendices |
constant-track | 35405 notes | Optimization hint; no visual defect or safe rewrite inferred | Current ledger |
| Skeleton counts | 231 files at 66 bones; 18 X Bot.fbx at 68 | Reference files need classification; common counts do not prove compatibility | Current inspect output |
AnimSmith remediation evidence

|---|---|---|---|---|
| MIX-OWN-001 | Archive-level XZ declarations | 52 stationary-root errors | Current per-file lint/measure; no output produced | Per-file intent/controller acceptance unavailable; residual unresolved |

Rig, masking, and compatibility evidence
| Pack/rig/set pair | Skeleton/retarget | Scale/axes | Root policy | Timing/blend | Overall evidence |
|---|---|---|---|---|---|
| Basic / Pistol proposed handoff | 66-bone counts and Mixamo roles on selected files; hierarchy/rest/deformation not compared | Not evaluated | Controller ownership proposed | Full-body transition not tested | not-evaluated technical/contact/artistic acceptance |

Limitations and unknowns
- Vendor mapping, loop/phase intent, target character, engines, retargeting, contacts, deformation, performance, networking, and artistic style remain unavailable.
- Cross-pack hypotheses are new evaluator scenarios; no historical membership or compatibility conclusion was reconstructed.
- Original ZIP payloads and controlling license evidence were unavailable; hashing covers extracted sources.
Changes between AnimSmith versions
AnimSmith 0.14.0 — Fresh source-only matrix admitted 249/249 files, revalidated mechanical/declared counts, and added bounded new controller/state hypotheses without claiming runtime acceptance.
AnimSmith 0.10.0 — Retained historical totals do not supply collection semantics. AnimSmith 0.7.0 evidence remains superseded.
