I completed a fresh live audit without changing the circuit, placement, outline, or routing.
Confirmed
0 airwires
USB clearance passes
ESP32 antenna keepout only flags its owning module
No verified defect was altered
Still preventing final approval
The board preflight returns a generic BOARD_DEFINITION_GENERIC validation error without identifying the underlying object.
Three protected USB breakout segments are reported as redundant but appear intentional; they were preserved.
Non-blocking advisories remain for D5 pin metadata and C6 decoupling placement.
An independent bare-PCB review completed, but I could not retrieve its final verdict. Therefore, the board is not yet certified for manufacturing. Execution stopped because your ACUs ran out.
I couldn’t retrieve and reconcile the executor’s fabrication report, so I made no additional changes and cannot honestly approve the board for manufacturing.
The last confirmed state still requires final verification of:
Zero airwires and unintended redundant traces
USB D+/D− breakout clearance and continuity
C6 decoupling warning
ESP32 antenna keepout warning
Complete fabrication DRC/DFM results
Do not order the PCB until these checks pass. Execution stopped because your ACUs ran out.
I couldn’t retrieve the completed ESP32 Board Review report, so I could not reconcile its findings or make any further verified corrections. The project remains in its previous state and is not certified for manufacturing.
The final approval still requires confirming:
0 airwires and no unintended redundant traces
USB D+/D− continuity and minimum clearance
No blocking board-definition or fabrication DRC errors
C6 decoupling and ESP32 antenna-keepout findings are advisory only
Outcome: failed/blocked through the currently exposed layout-rule API; zero U1 errors was not achieved. Investigation and fresh verification completed. No component moved, no routing performed, and both RF zones are unchanged after removing the temporary diagnostic ruleset.
Exact rule evidence
Top inherited zone UID 70bb0844-204e-435d-b450-d5a241608a6b__4b57c348-c412-4ec2-9ef6-c1aef73f6352: parent U1 footprint, position: 0 17, size: 48 22, computed.layer: Top, active.
U1 remains at (2, 11.5) mm, rotation 0°. Both zones cover the same world rectangle x=-22…26 mm, y=17.5…39.5 mm.
get_layout_rule_config describes keepOut as distance outside an object's bounds, with type-specific distances. It does not expose an interior-intersection exclusion switch.
Tested on both exact zone UIDs with a selector ruleset: keepOut: 0mm element(0mm) pad(0.1mm) via(0.1mm) routeSegment(0.1mm) fill(0.1mm) polygon(0.1mm) !important. The tool accepted and persisted the rule. Fresh keepout checks at 18:16:12 UTC still returned two U1 errors. Zero extra element clearance does not disable the zone/body intersection check. The ineffective diagnostic ruleset was deleted afterward.
Candidate controls componentKeepout, copperKeepout, excludeOwner, keepoutScope, and keepoutType each returned Unknown rule from the rule-config API; none was applied.
protected is supported only on net and polygon; its documented guarantee is that auto-layout will not route traces through the polygon. It is not a documented copper-free exclusion for pads, fills and vias. A net-owned copper polygon therefore cannot safely replace these RF zones on the available evidence, and none was created.
connectedLayers controls copper-layer connections, not component intrusion classification. The existing All-layer selector does not remove the two component intersection findings.
Final verification and safe next step
Fresh checks after removing the test at 18:16:38.685 UTC: 2 U1 keepout errors, no body-overlap, component-outside-board, edge-placement or pad-access findings. Both Top and Bottom RF keepouts were preserved without shifting, shrinking or disabling them. Other components remain prohibited by those zones; no exclusion was waived.
This confirms that the tested supported clearance-scope mechanism cannot express the needed owner exception, and no copper-only/owner-exempt zone control is exposed by the available tools. It is not a claim that an undocumented UI or future platform feature cannot provide one. The blocking capability is an owner-exempt or copper-only keepout classification (while retaining separate other-component exclusion), or a correction to the component-keepout checker. Do not use negative clearances, shrink the module body/courtyard, or remove RF geometry to manufacture a passing result. Internal feedback submission failed again; no ticket was filed.
Result
Partial completion; not placement-DRC-clean. No traces were routed. Final placement checks were refreshed on 2026-09-16 at 18:13:02 UTC and the final whole-board 2D image was inspected.
Assigned-scope status
Table
Item
Status
Evidence / limitation
C2/J1 body interference
Completed
C2 moved to (-10, 7) mm, 90°. Zero body overlaps in final check.
R2/U1/U7 conflict and pad escape
Completed
R2 moved to (9.5, -3) mm, 0°. Zero pad-access findings and zero copper-overlap findings.
J1 edge placement
Completed
Existing 270° outward-facing orientation retained at (-24.1, 11) mm. Board-specific edge offset is 5.9 mm, incorporating 0.5 mm assembly setback beyond the library 5.4 mm datum. Edge-placement findings cleared without reducing board keepout.
Component-outside-board
Completed
Zero findings. All 38 components remain top-mounted.
U1 antenna keepout DRC
Failed / blocked
Two U1 keepout errors remain: its own inherited Top RF zone and the matching explicit Bottom RF zone. The module antenna body necessarily occupies its own RF exclusion. Moving the component also moves the inherited zone; ordinary placement cannot remove this self-intersection. No zone was deleted or shrunk. Requires review of owner-antenna exclusion semantics, not removal of RF protection.
U7/J3 congestion improvement
Failed
Two alternate placements worsened the density classification, so U7 was restored to approved (16, 0) mm, 90°. Original two hotspot warnings remain near (23, -2) and (23, -6) mm.
Fresh checks and final 2D inspection
Completed
Geometry, placement checks and whole-board image inspected after final mutations.
Routing
Unattempted, intentionally
User requested no routing. Existing fill and six existing vias retained; no traces added.
Final changed placements
Coordinates are component origins in mm from board center; angles CCW.

J1/U2 remain in the northwest, J4 and the four ordered driver clusters on the west, J2/J3 on the east, J5/J6 and BOOT along the south, RESET at the west. Connector positions/pin ordering and all driver clusters were retained. U2 stays at (-14.8, 10.3) mm, 270°; the region south of its output tab is now less obstructed, but no thermal copper has been added or thermally validated.
RF exclusion
The inherited zone is 48 × 22 mm, centered at local (0, 17) mm within U1; at the final U1 position this is board center (2, 28.5) mm. Its board-coordinate span is x=-22…26 mm and y=17.5…39.5 mm. This intentionally extends beyond the north board edge. No other component body, pad or existing via was observed in this region. The original zone remains intact; an explicit Bottom zone with identical world geometry was added because the inherited zone readback continued to show Top despite an All-connected-layers selector rule.
The Bottom zone is board-relative: if U1 is moved later, move this Bottom zone by the same translation and rotation. Do not clear the two U1 errors by deleting, deactivating, or shifting either exclusion away from the antenna. Independent validation of the inherited RF dimensions against the hardware design guidelines remains open; the existing library geometry was preserved rather than guessed.
Remaining findings and acceptance
Error: two U1 component-keepout findings. Suspected owner/antenna self-intersection in the checker, supported by the footprint hierarchy and overlay image. Not waived and not claimed clean. The internal feedback submission failed, so no ticket was filed.
Warning: C2 decoupling loop area. Output-pad path is nearby, but regulator ground is on the opposite side. This remains a real return-path concern; not accepted as electrically validated. Final output-cap ground routing and regulator thermal copper need review.
Warning: C6 decoupling loop area. VCC proximity is good, but U7 GND is diagonally opposite. Requires short local return to the future ground plane; the placement warning is not treated as a validated routed loop.
Info/routing advisory: 53.3% component fill, 83.6% routing-aware fill; congestion near (23,-2) and (23,-6) mm for U7/J3 remains. A heuristic warning, not evidence of a failed routing attempt, since routing was not run. Do not assume routability is proven.
Expected routing-stage errors: 65 airwire findings at the most recent full DRC. These are acceptable only for this explicitly unrouted placement milestone, not for fabrication.
Visual follow-up: grouping and service access are preserved, but inherited silkscreen labels/values are crowded and overlap near passives and driver clusters. Silkscreen cleanup was not attempted in this batch.
Inspection discrepancy
The summary reports aggregate minimum X=-31.33 mm, apparently from treating J5's pin-1 origin as its body center. Exact SVG geometry places J5 at x=-28.8…-20.15 mm, y=-24.5…-20.9 mm; component-outside-board checks and the final image show it inside the outline. Use actual transformed footprint geometry rather than the centered summary box for this asymmetric header.
