  family <model-id>                      print the model family (anthropic, openai, google, ...)

Runners: codex-cli (repository review via codex exec), api (supplied-input review via
OPENAI_API_KEY/ANTHROPIC_API_KEY; needs --model), host-subagent (binds --result from a
cross-family subagent the host ran; needs --model). --native-model enforces the same-family
rule. GSTACK_OUTSIDE_RUNNER names the fallback when --fallback is absent.
Prints OUTSIDE_STATUS: <status> provider=<runner> model=<id> family=<f> and writes <out>.meta.json.
codex_reviews=disabled (or an unreadable config) refuses every runner before it starts:
OUTSIDE_STATUS: not_run reason=consent_missing, exit 3. Enable: gstack-config set codex_reviews enabled.
