wrapped_command.rs

//! What:
//!  Decide what one wrapped Git command does once real Git is known:
//!  forward it,
//!       possibly rewritten,
//!  or stop with policy events or a refusal.
//! Why:
//!  This is the whole lifecycle of a forwarded command in one place and in the
//!      installed wrapper's order:
//!  unported work is refused,
//!  configuration is loaded only
//!      for commands that need it,
//!  the policy pass runs,
//!  and a real push is stopped until
//!      its own lifecycle exists.
//!  A read-only command never reads configuration and asks
//!      Git at most where it runs.
//!
//! In TS you'd write (pseudocode):
//! ```ts
//! // const outcome = await runWrappedCommand(stripped, environment, checks);
//! ```

///  fact use and every ending stay out of the release executable.

///  Discover the scope of a manual push and hand it to the manual-push stage as its candidates.
/// Why:
///   The stage reads only what the push publishes, and the discovery runs against the repository the
///  command targets, with the invocation's global options and environment.
///
/// In TS you'd write (pseudocode):
/// ```ts
/// const scope = await manualPushScope({ gitPath, cwd, args }); // then the manual-push stage reads it
