An ECO could remove GND from the board's net table while a pad still sat on GND. In signex, a hand-edited change list could drop a net while a pad still named it, leaving the board inconsistent. The fix makes ECO validate and execute refuse the whole list and leave the board as it was.
Recurring agent failure issue in signex (alplabai)
What engineers report
A recurring agent failure problem in signex (alplabai) that mostly hits the electrical engineer.
Failure pattern: validation / failure
Analyst note
From the Grok pain-radar digests, Nov 10-11 2026 (Nov 10 8:41 AM ET through Nov 11 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-11: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000

Evidence
More recurring errors in signex (alplabai)
- A schematic PR merged while its review still requested changes, and open findings include the net-class picker keying on label text, child-sheet label LOCAL getting class nets LOCAL while the netlist calls it /LOCAL, assignments going to the last active project instead of the label's project, and unreadable sheets dropped silently.ECAD · impact 74
- A Signex polygon boolean returned a partial or inverted ring when inputs touched or nearly touched, a plausible-but-wrong shape feeding footprint courtyards.ECAD · impact 74
- A Signex project file saved with a UTF-8 BOM opened as an empty project and would have been replaced on the next save, and merge-conflict-marker files also opened empty.ECAD · impact 74
- Parts placed before a footprint was bound to their library row stay empty, and changing a row footprint later does not update parts already placed from it. ERC flags them, and the netlist and BOM go out without the footprint. MPN and manufacturer are not stamped at placement either, so ERC reports missing MPNs on parts whose library row has one.ECAD · impact 74
- Two footprints sharing an unannotated or empty reference get all their pads on the first one. The second has none and no error is raised.ECAD · impact 74
- A blocker for the headless command runner from last hour's #1923. Before the font scan runs, text width falls back to a monospace estimate, so a headless run computes different label hit boxes and flags than the GUI, and the result depends on the host's fonts. An agent and a person looking at the same schematic would get different checks.ECAD · impact 66
