The parts actually bought changed the design: an SSR instead of an active-low relay module, a USB phone charger instead of the HLK-PM01, a breaker instead of the 10 A fuse, an RGB button instead of a discrete LED and switch. STATUS.md and the firmware use GPIO21/22/23 for the LED while hardware/README.md says GPIO32/33/25, and the new architecture lives in a hand sketch that is the starting point, not a validated schematic.
Recurring agent failure issue in cafey (Tavaressan)
What engineers report
A recurring agent failure problem in cafey (Tavaressan) that mostly hits the electrical engineer.
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
