An SWD programming fixture stays BLOCKED. The connector tail length is now sourced from the Molex drawing, 2.3 plus or minus 0.5 mm, but the board thickness tolerance is not sourced anywhere, so every through-hole lead gets checked at its full length as a bound. Then an independent review had the spring hold-down rechecked at worst case, each spring anywhere in 6.35 to 10 N, and it fails. The verified flags stay false and the hold-down needs a redesign.

- A Claude Code project audited an LED board's order package: 64 footprints checked against the board, netlists, catalog and mechanical records. Cable pin maps between three boards now come from both netlists and fail on mismatch, and assembly side comes from pad data bound to the board's hash. 10 blockers stay open, mostly exact-part gaps (packing suffix, connector pin numbering, jack hole sizes). The order gate stays blocked. Mechanical, electrical and purchasing facts had to be tied together by hand-written scripts.ECAD · impact 66
- Changed boards ran DRC with KiCad default rules instead of the board own rule files, because the release gate mutation step did not load the board .kicad_pro and .kicad_dru. Mutated boards now run DRC with the board own rules, plus a control track that must trip the new 0.35 mm JLCPCB rule by name.ECAD · impact 66
- Docs were re-synced to the mechanical model after a cable length drifted between files: after a harness reroute and a connector move the power cable requirement became 57 plus or minus 3 mm, but the 56 plus or minus 3 text came from before the J5 move. Seven doc files had to be re-synced by hand, plus a BOM delta.MCAD · impact 66
- On a Eurorack LED module, the enclosure check accepted a placement file copied over, not tied to the actual PCB. The PR binds the chain and rejects stale identities, with open items including contradicting supplier evidence on jack terminals, zero switch stock and an LED timing mismatch.ECAD · impact 66
- The router is rerun in CI and the committed board is checked against the recorded route byte for byte. A lot of work to make sure the check reads the right rules.ECAD · impact 66
