## Current state
`ModelVersion.versionRange: versionRange` semantically conflates "this version" with "a range of versions". Example `claude-opus-4-7.yaml` has `versionRange: ">=4.7.0 <5.0.0"` which is a range, but `model:claude-opus-4-7` is intended to be one specific snapshot (`claude-opus-4-7-20251201` or similar). The repo agent-catalog distinguishes `ModelFamily` (range-bearing) from `ModelVersion` (concrete snapshot id).
## Desired state
- Rename `ModelVersion.versionRange` → `ModelVersion.versionId` (string, e.g. snapshot id).
- Move range-bearing claims to `ModelFamily.activeVersionRange`.
- Update example to `versionId: "claude-opus-4-7"` plus separate `aliasIds: ["claude-opus-4-7-20251201"]`.
## Evidence
- C:/work/v6/graph/schema/ontology-schema.yaml (ModelVersion attributes)
- packages/agent-catalog/graph/nodes/models.yaml (uses `modelVersionId` shape)
- https://platform.claude.com/docs/en/docs/about-claude/models/overview (snapshot date discipline)
## Propagation status
- Level 2: open
## Propagation chain
- Level 2: rename attribute, update 3 example model files, update compute-path.md.
## Notes
Naming/semantics gap. Cascades into Level 1 fixes for Anthropic models.
