3D pose record (Z-up, origin on the pad centre, seated) in component.models_3d; model_3d_step named; off-origin variant…
Record exact hero generator and display-font provenance
Add dashed copper, silk and pin-map inspection layers to component hero
Record settled native wiki viewer verification and scope
Bind component hero to reviewed marked model and document display provenance
Publish Adom-authorized marked contact and pin variants with permission provenance
Cache optional fitted MPN lettering and reviewed variant provenance
Correct GLB hashes using binary-safe downloads and validated container headers
Include legacy CAD aliases and optional variants in the per-file provenance inventory
Document per-file provenance, AI generation inputs, hashes and unresolved source evidence
1.2.3: align with library release
1.2.0: align version and provenance
provenance: add tsci source + public KiCad PCM feed
Title: 'MachineContactMedium' -> 'Machine Contact Medium' (human-readable, not camelCase)
hero: new consistent-size product photo (static image)
3D: solder balls top side only
Docs: reference John's solder-ball-layer standard + animated insertion
3D: add insert animation (contact lifts out + reseats) following John's mpin lead
3D: add 300um solder-ball ring (top+bottom) per John's adom-solder-ball-layer-standard, matching the mpins
Docs: rating 80% derated; solid-core mating wire
3D: FR4 thickness 1.55mm (1.6 clipped the floor; 1.55 clears with the contact protruding ~0.1mm)
3D: FR4 board thickness -> 1.6mm
3D: clean 4-quad outer walls on the hole board (fixes Babylon transparency-sort serration on FR4 edges)
3D: flush top (thin pad + contact rim at FR4 surface), thinner 1.0mm board so contact protrudes below and FR4 clears th…
3D: silkscreen ring sits ON the FR4 top face (was floating above it)
3D: lift model +1mm to clear the viewer ground floor
3D: real bare hole in FR4 (no copper plating) - contact sits in an actual opening like the large page
3D: pad as straddling washer (no coplanar face w/ transparent FR4) -> kill z-fighting; drop bottom pad
3D: remove hole plating (barrel) + fix bottom z-fighting (inset pad, raise seat clear of ground)
3D: show contact seated in transparent FR4 board with copper pads (insertion view, matches pin pages)
Fix 3D: rescale GLB to mm (was meters, viewer couldn't frame it)
