Openness score

A count of what is public, weighted by how much it takes to rebuild or retrain the robot without its maker. It reads from the robot’s package record; nobody scores a robot by hand. It measures openness, not quality or capability.

Formula

weights from @hs/registry

score = 25·cad + 20·bom + 20·sim + 15·firmware + 10·software + 10·policies
      where each term is 1 if public, 0 if not
      range 0 … 100

Weights

Artifact	Counts as public when	Weight	Robots
CADopenness.cad	Mechanical CAD for the robot is published in an editable or printable form.	25	13
Bill of materialsopenness.bom	A bill of materials with part names and quantities is public.	20	12
Sim model (URDF/MJCF)openness.sim	A URDF or MJCF model is public, so the robot can be simulated without the maker.	20	31
Firmwareopenness.firmware	Source for the joint or board firmware is public.	15	12
Softwareopenness.software	The robot's control or SDK software is public.	10	29
Trained policiesopenness.policies	Trained control policies (e.g. locomotion) or their training code are public.	10	11

Verification ladder (separate from openness)

L0	Indexed	Known to exist. Atlas page only.	20
L1	Compiled	Package validates against the spec; every fact has a source.	18
L2	Sim-verified	Loads in browser and GPU sim, mass within tolerance of the BOM, holds a stand. Unlocks .training.	14
L3	Sourced	Every BOM line resolves to a live offer in at least two regions. Unlocks the one-click cart.	0
L4	Built	At least one community build report with photos and bring-up logs. Unlocks Build it as the main action.	0
L5	Certified	The robot's maintainer signs the package. Unlocks certified teams and kit sales.	0

Openness says what is public. The level says what has been verified with evidence. A closed robot can sit at L2 because its sim model is public and loads; an open one can sit at L1 until someone proves it builds.
