Rewrite module READMEs around the current verified run and test paths, tighten repo_integrity_check.sh with fact-source checks, update supply-api migration baseline, and remove the platform-token-runtime audit query placeholder response.
Add repository integration probes, repository policy tests, the compose-based integration runner, and the matching usage documentation. Align the runner environment with both repository and middleware integration test expectations, and verify with fresh repository tests, integration-tag test runs, bash -n, and docker-compose config before commit.
- Add migrate.sh for sequential database migrations
- Migration order: platform_core -> supply_schema -> patch -> idempotency
- Support env var configuration for DB connection
