Reconstruct Fusion 360 Gallery body 36938_ae684b66_0002_2 (joint set joint_set_01184) as editable parameterized KCL in the part's native frame (bbox min [100, 0, 70], size [10, 88, 50] mm). The solid is a T: a 10 x 10 x 50 mm head with R4 vertical corner fillets and a Ø5 bore along z, unioned with a Ø5 shaft along +y to y = 88. Every hole, boss and shaft is an acceptance cylinder and every planar face level is a named face. One solid; export STEP and STL. Held-out reconstruction: the pipeline is frozen and the reference CAD is evaluator-only.
| Tier | Gate | Result | Evidence |
|---|---|---|---|
| A | contract_provenance Contract validates; stated/measured sources resolve to bundle files; no blocking open questions; interfaces pinned by checks | PASS | designs/fusion-01184-recon/contract.yaml: 16 parameters {'stated': 10, 'derived': 6}; sources unresolved {}; unanchored 0 |
| A | envelope Bounding box of the exported STEP equals the contract envelope | PASS | results/build123d/fusion-01184-recon/inspect.json bbox.max_error = 0.0 (tol 0.05) |
| A | mass_properties Volume, surface area and centre of mass within contract tolerance (independent STEP measurement) | PASS | results/build123d/fusion-01184-recon/inspect.json volume = 4863.7326 vs 4863.73 |
| A | features Every required feature, section, named face, cylinder axis, plane, dimension, body, clearance, passage, wall, gear and symmetry check verified on the STEP | PASS | results/build123d/fusion-01184-recon/inspect.json features: 4/4 ok; failed required []; failed optional []; unverified [] |
| A | reference_fidelity Deviation from the reference model within the contract band (when a reference exists) | n/a | results/build123d/fusion-01184-recon/inspect.json deviation.p95 = None hausdorff = None silhouette_iou_min = None |
| B | export_agreement Engine, STEP (OpenCascade) and STL (trimesh) volumes agree | PASS | results/build123d/fusion-01184-recon/inspect.json agreement engine=4863.732647132861 step=4863.73264713257 stl=4855.800323348056 (rel tol 0.002; independent=False) |
| B | edit_robustness Declared parameter edits rebuild with the expected effect, undriven interfaces stay put, sweeps regenerate, infeasible values are refused; baseline re-export hash unchanged | PASS | results/build123d/fusion-01184-recon/edit.json 2/2 edit tests ok; restore.ok = True |
| B | source_hygiene Dialect, units, formatted, lint-clean, named parameters match the contract, asserts present | PASS | results/build123d/fusion-01184-recon/verify.json hygiene: dialect=True unit=True legacy=[] params_ok=True asserts=13 |
| C | export_integrity Deterministic STEP (two exports identical), valid B-rep, expected solid count, watertight STL (solid shells == solids) | PASS | results/build123d/fusion-01184-recon/export.json step.deterministic = True sha256 1e151dd4f561; stl=present; glb=present |

| C | evidence_separation Contract agreement, reference agreement and physical validation are reported as separate verdicts | PASS | results/build123d/fusion-01184-recon/inspect.json carries contract checks (volume/bbox/features) and a separate deviation block (reference = None) |
