@@ -1,96 +0,0 @@-# Rework clips (2026-09-30)--The second, measured adom-aiflow run on this board: the EN and VOUT sense reroute that took them off B.Cu under the input hot loop, the pours landed again, the current and thermal analyses, and the full two-sided silkscreen placed live in KiCad, one label group at a time. The first build's clips are on the [build clips](clips.md) page.--> The silkscreen clip starts part way in: the first 23 label groups (the contact labels and TP1/TP2) went on before the recorder started, because `capture start` looked for the editor window that had been closed for the offline half. aiflow 0.1.38 fixes that. The clip came across from the test box in 200 MB parts (2.7 GB for 16 minutes).--Last updated 2026-09-30 10:15 UTC. 5 clip(s).--| # | step | visit | recorded | links | state |-|---|---|---|---|---|---|-| 1 | routing | 1 | 2026-09-30 01:34 UTC | [clip](#clip-1), [10x](clips/window-724124-20260930-013402-10x.mp4), [action](clips/window-724124-20260930-013402-action.mp4), [sheet](clips/window-724124-20260930-013402-sheet.png) | ok |-| 2 | pours | 1 | 2026-09-30 01:45 UTC | [clip](#clip-2), [10x](clips/window-724124-20260930-014523-10x.mp4), [action](clips/window-724124-20260930-014523-action.mp4), [sheet](clips/window-724124-20260930-014523-sheet.png) | ok |-| 3 | current | 1 | 2026-09-30 01:52 UTC | [clip](#clip-3), [10x](clips/window-724124-20260930-015230-10x.mp4), [action](clips/window-724124-20260930-015230-action.mp4), [sheet](clips/window-724124-20260930-015230-sheet.png) | ok |-| 4 | silkscreen | 1 | 2026-09-30 03:18 UTC | [clip](#clip-4), [10x](clips/window-724124-20260930-031802-10x.mp4), [action](clips/window-724124-20260930-031802-action.mp4), [sheet](clips/window-724124-20260930-031802-sheet.png) | ok |-| 5 | silkscreen | - | 2026-09-30 03:30 UTC | [clip](#clip-5), [10x](clips/window-527520-20260930-033042-10x.mp4), [action](clips/window-527520-20260930-033042-action.mp4), [sheet](clips/window-527520-20260930-033042-sheet.png) | ok |--### Clip 1: routing--<a id="clip-1"></a>--Step `routing`, visit 1.

Recorded 2026-09-30, 37.3 s. The part models were cleaned up so every marked part carries its MPN as a flat laser-etch mark, with the vendor colours kept: U1 (TPS54202DDCR) along its long axis; C1 (EEE-FK1V470P) on the silver field of the can, off the polarity stripe; C2 and C3 (CC1206KKX7R8BB106, which used KiCad's stock 1206 model before) with a light mark seated on the brown ceramic between the end caps; and every 0402 resistor and ceramic capacitor (R1 to R8, C4, C5, C6 to C8, C9) the same way. D1 (IN-S63BTG) has its lens tinted to the datasheet's 527 nm dominant wavelength and its MPN on the side of the lens, so the window stays clear. L1's vendor model already carries its AMPLH5030S marking, so it was left as it is. Each view is a native KiCad 10 render of the same board, before and after.--<video src="docs/clips/etch-cleanup.mp4" poster="docs/clips/etch-cleanup-poster.jpg" controls muted playsinline preload="metadata"></video>--The KiCad 3D viewer on the desktop could not be filmed this time, because another window was in front of it, so the clip is built from `kicad-cli pcb render` frames instead of a screen recording.
