Net-diff PR (2 of 4) splitting feat/unified-config-and-secrets. harmony_config + harmony_config_derive; compiles against master's harmony_secret. - ConfigClass + #[config(secret)] derive; class plumbed through ConfigSource - ConfigManager -> ConfigClient rename + for_namespace + Builder - per-class secret masking: input echoes '*', output renders '****' - get_or_prompt persists to every writable source - SQLite dropped from the canonical chain (cleartext-at-rest) + namespaced - prompt banner; serde-rename caveat docs; store-error logging - docs: ADR-020-1 names OPENBAO_URL/VAULT_ADDR; ROADMAP/01 + firewall_pair rename Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

//! Example demonstrating configuration prompting with harmony_config
|
|
//!
|
|
//! This example shows how to use `get_or_prompt()` to interactively
|
|
//! ask the user for configuration values when none are found.
|
|
//!
|
|
//! **Note**: This example requires a TTY to work properly since it uses
|
|
//! interactive prompting via `inquire`. Run in a terminal.
|
|
//!
|
|
//! Run with:
|
|
//! - `cargo run --example prompting` - will prompt for values interactively
|
|
//! - If config exists in SQLite, it will be used directly without prompting
