The existing [completed Version 27 task](https://adam.new/jacob-catalano/tasks?task=da122c5a-e392-47b7-a53f-a52d949eabb7) was read in the browser. Its existing final output was downloaded, inspected and compared with the earlier published checkpoint. No Adam MCP or new generation was used. Version 28 was authored in desktop Autodesk Fusion.

Final 27 package SHA-256: `c12f00178166087ff6ff732d757e157be37ae16e3b6b2cc16dea96d06405adc1`.

The final source contains 67 custom/prepared parts and 18 fasteners. Version 28 changes six cosmetic parts and adds six grille-stack components, yielding 73 custom/prepared parts, 18 fasteners, 182 CASE solids and 540 full-reference solids. The full reference includes 356 OEM solids and two nominal lead routes. The 92 mesh rods represent one purchased weave panel.

All 91 individual STEP exports are valid. Native Fusion verifies zero bidirectional material difference in the front-shell interior below Z=-2.21 versus the casting-adapted final baseline, and unchanged faces, volumes, bounds and transforms for 436 retained assembly-occurrence bodies. Coincident-face volume integration varies slightly across imports; preservation uses native bidirectional differences, not a volume-only comparison.

There are no unintended static interferences above the audit threshold. The inherited lens collector has a 0.592018 mm3 nominal press-fit interference requiring physical fit approval. All 60 sampled directional retention checks are blocked within 0.50 mm; this is geometry, not load or shock qualification. All four control sweeps are clear and reach their actual plungers; force, return and permissible overtravel remain unqualified. All 25 rear-cover positions and 18 staged driver approaches are clear. Both antenna service frames have clear sampled lifts. The zero-gap attachment graph leaves 19 bodies in the control, clamp and switch groups disconnected because running clearances and simplified threads do not form a continuous touching network. These are not counted as a contact-graph PASS: threaded mounting, six-axis OEM restraint and all 24 key-capture trials are reported separately. Actual clamping, key return and retention forces remain first-article tests.

The USB gauge is not an actual vendor-qualified plug. The 2.484173 mm3 receiver-reference overlap remains an explicit hold, not a PASS. Obtain a real plug and confirmed mating datum before approving this interface. Do not alter OEM PCB geometry to hide it.

The manufacturing route remains supplier-reviewed urethane casting with separate metal/mesh, optical, PA12 and soft-stock processes. Nominal casting masters contain no supplier shrink scale, mold splits, gates or vents. Physical first articles must qualify resin shrink/release, threaded pilots, pad forces, switch feel, optics, acoustics, RF, bonds, lead routing and durability.

The website, diagrams and exported CAD refer to this same checked build. Source inventories and SHA-256 manifests accompany the files. Earlier 27 options remain available independently.
