persist.rs

//! Persist config and secrets from QA apply-answers output.
//!
//! After a provider's `apply-answers` op returns a config object, this module:
//! - Writes every visible answer to the dev secrets store under
//!   `secrets://<env>/<tenant>/<team>/<provider>/<key>` (legacy universal
//!   write — WASM components have historically read both secret and
//!   non-secret config values through the secrets API).
//! - Emits a new sibling `pack-config-input.v1` file via
//!   [`emit_pack_config_input`] when the wizard scope is known. This is the
//!   C7 producer for the `pack-config.v1.non_secret` channel: the greentic-
//!   deployer picks up the file at revision-create, stamps the active
//!   `revision_id`, and writes the final `pack-config.v1` that
//!   [`RuntimeConfigHost`](https://docs.rs/greentic-interfaces-wasmtime)
//!   reads (C4). The universal DevStore write stays alive for one release as
//!   the C4.2 compatibility shim — runtime reads of non-secret keys fall back
//!   to it with a once-per-process deprecation warning.
//! - Provides filtering to separate secret from non-secret fields.
