# Results on public wiki boards

22 boards from public wiki pages were stripped of their tracks and vias and routed again with `adom-aiflow-routing`, then judged by KiCad's DRC with zones refilled, under each board's own rule values with clearance and open connections forced on. A board is clean when every connection is made, KiCad reports 0 open, and KiCad finds no copper error that the original does not also have.

First run: 9 of 22 clean. Current revision: 19 of 22 clean.

## Before and after

Each picture shows the original, the first run and the current run, with the connections KiCad reports open ringed in red.

| Board | What changed in the router | Picture |
|---|---|---|
| amfm-receiver-molecule | pour pieces are stitched to their net; a last-mile repair searches the final joins deeper | [before-after/amfm-receiver-molecule.png](before-after/amfm-receiver-molecule.png) |
| carrier-fc-rp2350a-mini | a USB pair that could not be coupled was frozen as two stacked tracks, a wall on both layers; it is now movable and may not stack | [before-after/carrier-fc-rp2350a-mini.png](before-after/carrier-fc-rp2350a-mini.png) |
| combiner-molecule | no project file: the router now works to KiCad's own defaults | [before-after/combiner-molecule.png](before-after/combiner-molecule.png) |
| drone-motor-carrier-assembly | no project file: the router now works to KiCad's own defaults | [before-after/drone-motor-carrier-assembly.png](before-after/drone-motor-carrier-assembly.png) |
| drone-motor-carrier | a coupled pair's two tracks are now measured against each other at the pad entries | [before-after/drone-motor-carrier.png](before-after/drone-motor-carrier.png) |
| esc-g431 | vias without a track keep their net, a do-not-populate part is wired, thermal-relief cost. Still open: two layers, many small pours | [before-after/esc-g431.png](before-after/esc-g431.png) |
| rf-workcell-module | no project file: the router now works to KiCad's own defaults | [before-after/rf-workcell-module.png](before-after/rf-workcell-module.png) |
| rp2350a-ads1220 | supply-pin-to-capacitor stubs are laid first; vias and tracks keep KiCad's polygon tolerance from mask openings | [before-after/rp2350a-ads1220.png](before-after/rp2350a-ads1220.png) |
| tmf8829-molecule | no project file: the router now works to KiCad's own defaults (0.2 mm track and clearance, 0.5 mm edge) | [before-after/tmf8829-molecule.png](before-after/tmf8829-molecule.png) |

## Every board beside its original

`boards/` holds a picture of each board: the original on the left, the routed board on the right.

| Question | Picture |
|---|---|
| What sizes a supply rail when the board has no current spec | [questions/rail-width.png](questions/rail-width.png) |
| RF lines, via fences and ground stitching, which the board file does not ask for | [questions/rf-copper.png](questions/rf-copper.png) |

## Data

| File | What it holds |
|---|---|
| [table.json](table.json) | the table above as data |
| [ledger.jsonl](ledger.jsonl) | two records per board, first run and current: connections made, the router's own check, KiCad's result on the original and on the routed board, the router's notes |
| [lessons.jsonl](lessons.jsonl) | one record per lesson: what was found, what was changed in the router, how it was verified. Boards that are not public are described, not named |
