A part's Gerber silkscreen layer follows its Board Side in IGerberComponentSimple's default, so the exporter no longer swaps layers after the fact and GerberLayer.flip() is gone

| The side is the physical fact. Z-order stays paint order and is not tied to it | Boards are drawn opaque, so painting bottom parts beneath the board would hide them. Bottom-layer traces already follow this rule. |
|
||||
| The canvas shows the side visually and does not rely on z-order for it | That is what removes the ambiguity of a "bottom" part drawn above the board. |
|
||||
| The side is a plain property, and the app never mirrors a part for the user | Seen from above, a part under the board is a mirror image, so a part with an asymmetric footprint moved to the bottom also needs Mirror Horizontally. Doing that for the user was tried as a Flip to Other Side action and dropped as menu clutter; the user sets the side and mirrors the part where needed. |
|
||||
| The Gerber layer is swapped centrally, not inside each component | Components keep emitting their `*Top` layer. One place maps it to the other side. |
|
||||
| The Gerber layer follows the side in the `IGerberComponentSimple` default, not in each component or in the exporter | Side and layer are decided in one place on the part, with no adjustment afterwards. None of the sided parts overrides `getGerberLayer()`. |
|
||||
| Default `_2` (Top), with `null` meaning Top | Fields added to existing classes deserialize as `null` in old files. |
|
||||
| Bottom-side text is mirrored centrally in the Gerber output | Parts draw their labels readable from the top, which is backwards on the bottom silkscreen once the board is turned over. While `GerberExporter.drawComponent` draws a bottom-side part, `GerberG2DWrapper.setMirrorText` mirrors each string about the centre of its layout box, so no component changes and the canvas keeps readable labels. |
|
||||
| A part without a side placed in the mirror is placed unchanged | A jumper, eyelet or wire has no side to set, so it is placed at the reflected point like any other part rather than refused. |
