GPT-6 Astra in Codex inside Hydrogen routed the shared Fable-placed ESC G431 fixture on arav-rog, Windows user arav, KiCad 10.0.3 and kicad-bridge 1.0.3. This is an independently calculated routing candidate. No Freerouting or other model's routing plan was used. The component placement and two existing inner planes were preserved. The board was never saved.

Result: 0 new DRC errors, 13 inherited errors, 13 unconnected items. 49 of 59 routable nets are fully connected after native zone refill. 58 distinct nets received copper. The accepted take has 64 successful route_net commits, 1863 native segments, 204 through vias and 1273.411 mm of track centerline. It is not a completed or fabrication-ready ESC.

Planning to the first route_net request, which was a dry run: 260.081 s. Accepted replay routing, first commit request to last response: 361.717 s. That routing measurement includes per-net DRC and the one-second viewing pauses. The full task accounting includes planning refinement, two discarded takes, capture diagnostics, resets and publication through its stated cutoff.

The final video is 384.9 s, silent, 1920-wide H.264/yuv420p with faststart. No cuts, speed changes or fabricated frames were applied to this take. It begins with an eight-second untouched-board hold showing 0 tracks and 0 vias, then the native commits, then validation and a final hold. The recorder's wall-clock duration is 386.784 s. A single Python worker updates an elapsed-time desktop caption to prevent the recorder's sparse-frame behavior; it does not plan or commit routes. The router and its C++ search helper run serially, with zero AI sub-agents.

Method and constraints:

  • Read the live revision and pad/net coordinates, then parsed the fixture's actual copper pad geometry, including custom MOSFET shapes, pad clearances, plated holes and board outline. Used an independent eight-direction A* search over F.Cu and B.Cu, initially at 0.1 mm and then at 0.05 mm for the MCU pin pitch. The small exact-pad-to-grid links can have non-45-degree angles; this is not claimed to be a fully octilinear layout.
  • Kept the specified 0.25 mm signal width and 0.8/0.4 mm through vias. Used 0.5 mm power connections and widened 31 clearance-safe power segments to 1.0 mm. Native DRC preflight remained enabled for every routing call.
  • Reserved individual short plane stubs for the GND and +3V3 SMD pads. Existing through-hole pads reach the inner planes. Signal routes stay on the outer copper layers. The initial file has its stackup and pad/zone settings but no embedded netclass block or sibling project rules; the explicit widths/vias follow John's fixture contract and native default clearance is 0.2 mm. Larger footprint-specific clearances were preserved.
  • Routed short nets first. Each call carried the previous accepted revision and created native undo items. Large branched nets and width groups use multiple calls for the same net, always one net per call.
  • The shunt and INA stay at the supplied placement. GND follows the requested plane-stub rule, so the sense inputs are not a separately routed Kelvin pair. The long fixed-placement sense connection and the remaining gaps require electrical/layout review. This demo does not establish motor-current capacity or thermal qualification.

These remain after repeated clearance-safe path searches against the fixed placement and accepted copper. This planner did not find the dense MCU/buck escapes and 0.5 mm phase-sense escapes at the gate driver within its 1.5-million-expansion search limit and required 0.8 mm vias. This is a limitation of this candidate and planner, not a proof that the board cannot be fully routed. No pads were moved and no rule was bypassed to force completion.

Native validation: errors=13, unconnected=13, warnings=64, zonesRefilled=True, violationReportMayBeTruncated=False. The inherited error type/item UUID sets match the initial fixture. Error types: {"clearance": 7, "malformed_courtyard": 6}. Full validation and the remaining item UUIDs are attached. Validation refills a disposable live-board snapshot; the editor status bar can still show the larger ratsnest count from its unfilled plane outlines. The reported 13 comes from the native refilled DRC, not that status-bar count.

Rejected, retried and discarded:

  • The desktop's transfer gate initially required approval for write_file_chunk. Waited for the grant, then retried the original transfer to arav-rog.
  • Rejected the initial 0.1 mm planner candidate for missed dense pad escapes. Refined to 0.05 mm, added same-net drill spacing, allowed legal pad-edge starts and reduced the planner's extra clearance margin while keeping the native 0.2 mm requirement. Native dry runs checked the resulting geometry.
  • First complete live pass: 13 inherited errors and 15 unconnected. Discarded its recording: 361.286 s recorder wall time became 201.489267 s of media, with long static intervals missing and early copper updates not reliably visible. Checked the Appearance panel, tried a background refresh key, and focused the canvas. No board geometry changed in those display diagnostics.
  • The reset initially exceeded remove_route's 1024-item limit and was refused. Reset only this task's copper in accepted batches of at most 1000 items, verifying the original zero-copper revision afterward.
  • The second take stopped when a +VBAT width-group exceeded route_net's 128-path limit. The rejected call landed no copper. Preserved that failed take and split the net into permitted batches before the final replay. No final-take route was forced past validation.
  • Two added connection repairs and the 1.0 mm widening groups passed native dry runs. The final take replayed the revised independent geometry from the verified untouched fixture. Both prior takes and all their calls are included in task costs, but excluded from the accepted-take performance metrics.
