On Windows 11 the native viewer shows component bodies as grey boxes and the mechanical tab fails a valid STEP with 'converter produced no model'. Two path bugs: it never looks in the Windows KiCad profile under %APPDATA%\kicad, and the model cache defaults to /tmp, which native Windows code and the shell-launched converter resolve to different folders. Separately, a requested GLB is acknowledged but the viewer silently loads a different file from mech/, while the STEP assets and model assignments were fine the whole time.
Recurring agent failure issue in Backplane (BackplaneWorks)
What engineers report
A recurring agent failure problem in Backplane (BackplaneWorks) that mostly hits the electrical engineer.
Failure pattern: validation / silent failure
Analyst note
From the Grok pain-radar digests, Nov 11-12 2026 (Nov 11 8:41 AM ET through Nov 12 5:41 AM ET digests plus the Haitch editions). Verified live 2026-11-12: 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 Backplane (BackplaneWorks)
- In a real project the 29 x 22 mm board existed only in a sibling worktree while main held a 70 x 50 mm draft at the same path, and the project page showed the wrong board. Seven thread worktrees sat on one old commit with nothing saying which design was current. Boards and schematics can only be merged by taking one side whole, so per-agent branches do not work for hardware.PDM · impact 74
- Among several contributor fixes, a failed CAD export now stops publication of release outputs and keeps the original error. The new export-error tests are included but haven't run.MCAD · impact 66
- STEP models were meshed at 0.1 mm and 0.5 rad, so a circle came out about 12-sided in the viewer. The new default on a 131-part assembly goes from 62k to 162k triangles, and reviewers were looking at a coarse copy of the real geometry.Verification · impact 66
