Problem
The annotation asset path can currently coerce missing or invalid dimensions to 0 × 0. That can allow an invalid descriptor frame to reach suggestion preparation instead of failing at the boundary that owns asset validation.
This was observed during the Phase F browser-suggestion work and is intentionally separate from the Phase G model registry/cache work in #876.
Desired outcome
- Identify where valid asset dimensions are lost or defaulted to zero.
- Reject or repair invalid dimensions at the appropriate existing boundary.
- Add regression coverage for the affected server and browser suggestion paths.
- Preserve the current annotation and suggestion contracts for valid assets.
This task should not redesign browser model acquisition or persistence.
