model_policy is now honored on the default claude runtime — including the anthropic-fable Claude Fable 5 preset. (#1133)
Previously, setting a model policy (e.g. anthropic-fable + high) had no effect on the default claude runtime: agent model resolution silently fell back to model_profile, and no warning was emitted. The policy only worked on non-claude runtimes (e.g. opencode), so users believed Fable 5 was active when it wasn't.
Now the policy resolves on claude too:
- Policy-resolved model IDs are mapped to Claude Code agent aliases — e.g. claude-fable-5 → fable, claude-opus-4-8 → opus, claude-sonnet-4-6 → sonnet.
- A policy value that is already a bare alias (e.g. fable) is used as-is.
- An ID with no corresponding Claude alias (e.g. a pinned claude-opus-4-5) emits a one-time warning and falls back to the configured tier alias, rather than returning a model the Agent tool can't spawn.
- Non-claude runtimes are unchanged (still resolve to full model IDs).
After upgrading, an anthropic-fable + high policy resolves the opus/sonnet tiers to the fable agent alias as documented. You can verify with:
```
node ~/.claude/gsd-core/bin/gsd-tools.cjs query resolve-model gsd-executor
# → { "model": "fable", ... }   (previously "sonnet" / "opus")
```
