A hole-to-zone clearance gate flagged 40 violations that did not exist, so CI on master could not go green. The custom check compared each drilled hole with each zone's bounding box; the pours cover the whole 71.1 x 79.1 mm outline, so 8 holes times 5 zones gave 40 'verify keep-out' records, none real.

Evidence
More recurring errors in balloon-fresh (felixfelix-bot)
- A base-station board had 143 electrical errors. 74 came from a copper pour that was never refilled, and the shipped board was built from a superseded netlist: the ERC-gated netlist has 53 parts while the board had 44, with twelve missing including the whole MCU decoupling ring and three removed resistors still on it. A netlist integrity test already failed on master and nobody acted on it, and refilling the 44-part board would have produced a board that looked clean while missing those caps.ECAD · impact 74
- A dead boot pin was invisible in every count the project published. /IO0 was a single-pad net because the netlist was grown by text transform, and a one-pad net cannot be reported as unconnected. A renamed copy of the board silently lost its .kicad_dru rules and reported 537 violations instead of 16, and a sibling commit reported 15 to 12 from a work copy with a different baseline while the board of record went from 11 to 12. Four more nets have the same defect with no free GPIOs to fix them.ECAD · impact 74
- An agent working on a fabricated hub board traced 3 failing connectivity tests to the tests and tools, not the board. The test and the pin registry both pointed at a superseded board file that was never fabricated, which produced 18 phantom 'pin absent' and 18 phantom 'not on board' drifts. One real drift remained: a commit changed U1.27 on the board without updating the registry. Worse, the suite had never run in CI, because the CI job did not install KiCad and 8 of 10 tests skipped quietly.ECAD · impact 74
- Both CPL generators used KiCad's footprint anchor, which sits on pad 1 for pin headers, instead of the pad-array centre, so J_HUB_PV was 5.080 mm off and J_PROG 6.350 mm off and JLCPCB would have placed them where the pins cannot enter the holes. The existing check claimed verification to <0.001 mm, converted to JLC coordinates and back to the same anchor value, and the two generators also disagreed on board size, 72.10 x 80.10 vs 72.00 x 80.00.ECAD · impact 74
- Every one of 14 pads referenced F.Mask but the board had none, so the export gave 9 files and zero mask gerbers, with SS24 diodes on 1.6 x 1.9 mm lands next to the cell string. Regenerating the file silently reduced the board from 32 track segments to 7, and the fix was to restore from git and patch the layer table directly.ECAD · impact 74
- kicad-cli DRC 0 was unreachable by construction because 16 two-face wing pads and 3 GND zone stitcher records were counted as opens. A release gate that can never pass becomes a formality people learn to override, so exclusions are now derived from board geometry instead of a hand-written list.ECAD · impact 74
