-Implement `open-reuse validate` with:
-
-- Schema validation of one or more `*.integration.yaml` files (default: scan
-  `registry/integrations/` if present).
-- Index checks: every `indexes/integrations.yaml` row has required fields; `id`
-  and `reuse_mode` are consistent when the definition file is reachable.
-- `--fail-on-warnings` for promotion-gate checks (missing maintainers on
-  `active` status, missing index row for local definitions).
-- Exit code 0 on success, non-zero on errors.
+Result 2026-06-24: Implemented schema validation, index consistency checks,
+`--repos-base` external definition resolution, and `--fail-on-warnings`.
