  "source": "You can now configure a Cogitave service and manage its secrets safely.\n\nIn this module, you:\n\n- **Classified** every value as a domain invariant (a named code constant), a\n  deployment parameter (typed config), or a secret (a `SecretRef`), using the\n  12-Factor litmus test to draw the line.\n- Assembled config through the **precedence chain** - defaults, `config.toml`,\n  `config.{env}.toml`, `COG_*` env vars, then CLI arguments - where later wins,\n  and selected the environment by **which overlay file loads**, never by branching\n  on the environment name in code.\n- Parsed config **once at the boundary** into one typed, immutable value that\n  **fails closed** on invalid or missing input, with a precise, layer-attributed\n  error.\n- Kept secrets out of git with the **three planes**, held a **`SecretRef`** in\n  config that resolves at runtime, and used **dotenvx** to commit only\n  encrypted-at-rest `.env` files with the private key held in the store.\n\nThe single idea underneath all of it: nothing environment-specific is hardcoded,\nevery secret is a reference, and a misconfigured service refuses to run rather\nthan fail deep in production.\n\n## Next steps\n\n- @cogitave.learn.secure-sdlc - the next module in **Cogitave engineering\n  standards**, on the controls and lifecycle gates a product carries beyond\n  configuration.\n- The **configuration standard** is the canonical reference, in the estate's\n  standards repository, for the full conformance checklist, feature flags via\n  OpenFeature, and config-as-code drift control.\n- The **secrets & environment standard** and **ADR-0008** are the estate's\n  canonical references for the secret store, rotation policy, and dev-env\n  handling in full.\n",
