* fix(routing): auto-migrate v0.3.0 inline routing_preferences to v0.4.0 top-level Lift inline routing_preferences under each model_provider into the top-level routing_preferences list with merged models[] and bump version to v0.4.0, with a deprecation warning. Existing v0.3.0 demo configs (Claude Code, Codex, preference_based_routing, etc.) keep working unchanged. Schema flags the inline shape as deprecated but still accepts it. Docs and skills updated to canonical top-level multi-model form. * test(common): bump reference config assertion to v0.4.0 The rendered reference config was bumped to v0.4.0 when its inline routing_preferences were lifted to the top level; align the configuration deserialization test with that change. * fix(config_generator): bump version to v0.4.0 up front in migration Move the v0.3.0 -> v0.4.0 version bump to the top of migrate_inline_routing_preferences so it runs unconditionally, including for configs that already declare top-level routing_preferences at v0.3.0. Previously the bump only fired when inline migration produced entries, leaving top-level v0.3.0 configs rejected by brightstaff's v0.4.0 gate. Tests updated to cover the new behavior and to confirm we never downgrade newer versions. * fix(config_generator): gate routing_preferences migration on version < v0.4.0 Short-circuit the migration when the config already declares v0.4.0 or newer. Anything at v0.4.0+ is assumed to be on the canonical top-level shape and is passed through untouched, including stray inline preferences (which are the author's bug to fix). Only v0.3.0 and older configs are rewritten and bumped. |
