 ### Phase A: Mechanical Extraction (1-3 days)
-- [~] JsonConfigService: extracted config document load/merge helpers into `src/services/impl/json_config_document_loader.cpp` to isolate parsing + extends/@delete merging.
+- [~] JsonConfigService: extracted config document load/merge helpers into `src/services/impl/json_config_document_loader.cpp` plus small parser/extend/merge services to keep files <100 LOC.
+- [~] JsonConfigService: split schema validation/versioning/migration into `json_config_*` services (`schema_validator`, `version_validator`, `migration_service`).
 - Move self-contained helpers into `*_helpers.cpp` with clear headers.
 - Extract pure data transforms into free functions with unit tests.
 - Preserve public interfaces; no behavior change in this phase.
