  "instruction": "MIPI Intra-Pair Length Matching The file `/home/user/Desktop/mipi.kicad_pcb` contains a 2-layer board with 5 MIPI D-PHY differential pairs (CLK, D0, D1, D2, D3) already routed on F.Cu. Use KiCad 10.0.2; run `kicad` for the GUI or `kicad-cli` for scripting/headless use (use PATH or the full install path). On this machine, the installed KiCad tools are `/usr/bin/kicad-cli`, `/usr/bin/pcbnew`, and `/usr/bin/eeschema`; use the one that matches the board or schematic operation.\n\nEach pair has an intra-pair skew of approximately 300 um; the `_N` trace of each pair is longer than the `_P` trace. Add serpentine segments to the shorter trace of each pair so that the intra-pair skew (`|L_P - L_N|`) is reduced to 75 um or less. Do not modify the `_N` traces. All traces must remain on F.Cu. Requirements: 1. For each of the 5 pairs, the absolute difference between total `_P` and `_N` routed lengths must be 75 um or less. 2. All MIPI segments must remain on F.Cu, with no layer changes. 3. The `_N` trace lengths must not change from the original file. 4. The serpentine segments must maintain at least 0.1 mm clearance to adjacent segments. 5. The output file must parse as a valid KiCad PCB s-expression. 6. Also write `/home/user/Desktop/fcu.svg` as the native KiCad CLI F.Cu SVG export of your final board. Write `/home/user/Desktop/mipi.kicad_pcb` and `/home/user/Desktop/fcu.svg`.",
