# config — reference JSON (non-secret)

Files such as `address-inventory.chain138.json` and `runtime-env.chain138.json` are **reference snapshots** produced during dotenv cleanup. They hold **public** contract addresses and RPC URLs — not private keys or API secrets.

- **Do not** treat these as a replacement for `.env` where secrets are required.
- When Chain 138 deployment addresses change, update canonical docs (parent repo `docs/11-references/ADDRESS_MATRIX_AND_STATUS.md`) and refresh these files if your tooling depends on them.

See parent repo `docs/00-meta/SUBMODULE_HYGIENE.md` for submodule workflow.
