### `check_footwear_fit`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use for a specific finished footwear product and the person's reported interaction. English is the primary consumer-language coverage; full Chinese interpretation is deferred. Without a complete approved canonical request, the three limited prototype paths are activity-related compression or numbness, instep pressure with a width comparison, and downhill toe-front contact. Heel retention, blister and ground-traction concerns can be acknowledged but cannot receive a new formal judgment or corrective prescription here. Prototype results are not formal Core conclusions. Do not use for cross-brand recommendations, product ranking, generic shoe education, style advice, simple size conversion, or medical diagnosis/treatment. When presenting a returned fit judgment, preserve the tool's decision, unknowns, next steps, alternatives, professional boundary, evidence state, and execution provenance. When coreJudgment is present, preserve its primaryState, reasonCodes, criticalUnknownIds, Case/Rule Set identity, and do not replace them with stronger host conclusions. Do not add or strengthen unverified product facts, gait or biomechanical labels, medical causal explanations or diagnoses, or extra size/width/lacing/product prescriptions unless they were independently established as verified evidence in the request. Keep any separately sourced external information clearly separate from the bounded fit judgment.
```
