Failure pattern: validation / failure
Analyst note
From the Grok pain-radar digests, Nov 8-9 2026 (Nov 8 8:41 AM ET through Nov 9 6:41 AM ET digests plus the Haitch editions). Verified live 2026-11-09: 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 kicadts (tscircuit)
- A legacy locked flag on PCB tracks was read as unlocked and dropped on save: before the fix, four of eight lock-state regression cases failed. A round-trip through the TypeScript parser quietly unlocked tracks a designer had locked, and native KiCad loading was not run.ECAD · impact 66
- The library serializes generator_version 8.0 without quotes. KiCad reads it as a number and refuses the library, and kicad-cli 10.0.1 exits 2 with 'Unable to load library.' The fix in #110 quotes it.ECAD · impact 66
- The serializer dropped pad zone-layer connections and wrote an empty expression. A round-trip through the TypeScript parser silently lost zone-layer connectivity.ECAD · impact 66
