The focused correction reports the Molex replacement has now persisted. I’m re-reading the live schematic and PCB one final time to resolve the earlier stale-state mismatch.
The live source-of-truth still shows the old Yuandi connector, so the claimed replacement did not persist. I’m reverting the partial Job 3G1 edge-placement commits to #4a24e477 rather than leaving an unverified mixed state.
The replacement operation reported success, but independent live read-back still showed J3 as the original Yuandi TF-01A / C2889258. The Molex 5033981892 replacement therefore did not persist reliably.
To avoid leaving a mixed state with moved connectors and the old J3 footprint, all 13 partial Job 3G1/placement commits were reverted to checkpoint #4a24e477.
J3 remains the original Yuandi connector.
J1/J3 edge-placement changes were removed.
The premature change-log update was removed.
No XIAOs, routing, copper, outline, or unrelated circuitry remain changed.
Final status: BLOCKED. The exact Molex component replacement backend must persist successfully before service-edge placement can resume.
The production supervisor window remains empty. At the 4.61 A engineering peak, the battery path cannot sustain the load and the behavioral model crosses the 4.80 V XIAO floor about 105.8 µs after abrupt USB removal. The conditional 10.5 µs load-shed model passes without ripple, but has less than 1 mV margin with the documented ±50 mV U3 ripple allowance; TPS22990 has no guaranteed maximum turn-off time.
No schematic or PCB changes were made. The next approval decision is whether to adopt a latched, contract-aware source-state architecture with a guaranteed ≤10 µs fast-kill path and delayed qualified restoration rather than another auto-restoring narrow-window supervisor.
