sourcing: part marking wording
Laser-etched part models on the board (U1, C1, C2, C3) and clip 6: STEP cleanup before and after
gaps 43 and 44: flat etch mark, local OpenCascade opt-in
U1 flat mark with its colour stored
gaps 40 to 42: MPN etch, component heroes, clips page per run
clips page: owner marker for the first run
Restore the build clips page (the rework run's report push had rebuilt it from that run's clips only)
aiflow run buck-12v5v-molecule-claude-opus-5-5-20260930-0108: 3d
U1 model laser-etched with its MPN along the long axis, colours kept
Dashboard screenshot from adom-spice-skillpack 0.2.2 (same results)
Rework clips page: reroute, pours, analyses and the live silkscreen
aiflow 0.1.38 closes gaps 36 to 38
design: 3.7 % step at the corrected 1 A load
Simulation: TI model at the corrected 1 A load, and ngspice, LTspice and PSpice for TI agreeing on all 8 measurements in the Adom SPICE dashboard
Rework: EN and VOUT sense off B.Cu under the input hot loop; full two-sided silkscreen per aiflow-silkscreen; molecule 1.0.2; new hero
Transient simulation corrected to a true 1 A load (the first runs were at 1.5 A); TI comparison marked for re-run
Poster frames for every clip; the build video at the top of the README
aiflow 0.1.37 closes every gap; BOM covers the molecule contacts and pins; spec uses molecule, fab.rules, planeUnder, chains, requireEvidence
Layout names the Hydrogen molecules: john/buck-12v5v-1a-molecule and john/Scaffold LrgMed 64x64
Delete kicad/rules/inhouse-2L.kicad_dru
Set hero billboard: 12 V to 5 V, 1 A buck molecule
Name the fab as a 3rd party fab; rules file renamed fab-2L; hero is the 3D board render
gap 35: the four unpulled clips were cleaned off the desktop
gap 35: clip pulls that fail silently
aiflow 0.1.34 skills and 0.1.35 compose fixes in the gap status

Link the published molecule page; layout names john/buck-12v5v-1a-molecule
Full write-up: design, simulation (ngspice and TI PSpice), sourcing, board, thermal and current, scaffold with probe plan, aiflow run; sources for design, sim, KiCad, molecule and scaffold
