Adversarial-review follow-ups to the lingo measurement() field:
- Add a `positive` option (strict > 0) and use it for the non-zero dimension
params. Swapping z.number().positive() → measurement(..,{min:0}) had started
admitting 0 (the core node schemas have no positivity backstop), so a zero-size
wall/opening/roof could be created. Inclusive-0 fields (overhang, sill height,
knee-wall height, opening offset, roof pitch) keep min:0.
- Escalate AMBIGUOUS_NUMBER to error so "1,234" fails instead of silently reading
as 1234 — a 1000x hazard for European decimals. Matches lingo's own /ai fields.
- roofLevelElevation reverted to z.number() (it's a level ordinal, not meters);
radians fields now advertise radian-appropriate examples.
