tools/check_bom_mesh_sync.py now fails CI when a printed part's Unit_Mass_g differs from its mesh mass, and lists printed rows with no mesh as NOT COVERED. Densities now come from one file checked against the 3D Systems sheets, moving hover weight from 13.80 to 14.12 lbm. The assembly check found the nozzle spigot overlapping the cartridge by 1,562 mm3, fixed by shortening the cartridge 3 mm, and no route for 4 x 10 AWG from the spar bore, with 1.5 mm free radius against 6.64 mm needed.
Recurring agent failure issue in Serenity-UAV (Stab-Rabbit-coding)
What engineers report
A recurring agent failure problem in Serenity-UAV (Stab-Rabbit-coding) that mostly hits the mechanical designer.
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
A modeled estimate with medium confidence. Swap in your own team size and loaded rate to size it for your team.

- A reshaped Observer board outline and slot keepouts leave copper running to or past the new edge, giving 9 hard copper-to-edge clearance violations, 8 at 0.0 mm against a 0.5 mm rule, and KiCad CI fails.ECAD · impact 74
- A UAV project pins its design revision at Rev U by moving the "Current design revision" header from Rev T to Rev U in 27 subsystem README, WBS and TODO files, plus the root README, docs index and tool BOM pointers. The new bom_revU.json is "a row-for-row carry-forward of bom_revT", and "the known BOM lag items remain documented as open." Subsystems keep their own generation names (PCB "Rev T", landing gear "R6", wing "S1g", nacelle "S4c"). The list of work carried into Rev U is "summarised from commit subjects, not signed off," and there is a rev-S git tag but no rev-T.PLM · impact 74
