//! Typed per-handler reports.
//!
//! Every CLI handler returns one of these structs instead of `()`.
//! In v0.14 the structs are minimal data carriers — the dispatcher
//! discards them via `let _ = handler.await?;`. v0.17 will read
//! the populated fields and emit them as OTel span attributes (per
//! the synthesis §6 matrix).
//!
//! Naming: one type per top-level subcommand. Fields are restricted
//! to ALLOW attributes from the v0.14+ §6 matrix; DENY data
//! (values, URI paths, raw error messages) never lands here.
//!
//! See [[build-plan-v0.14-redact]] §Phase 6 and
//! [[v0.14-plus-synthesis]] §6 for the rationale.
//!
//! # Phase 7 code-review B1: `Drop` does not fire on `secretenv run`
//!
//! The Phase 6 commit message described v0.17 wiring as "the
//! report's `Drop` impl emits the root span." That works for handler
//! paths whose function bodies return normally (`cmd_get`, `cmd_redact`,
//! `cmd_resolve`, `cmd_registry`, `cmd_setup`, `cmd_profile`,
//! `cmd_completions`) but **does not work for `cmd_run`'s exec /
//! pipe-redact happy paths**: both end in `std::process::exit(...)`
//! or `cmd.exec()`, which replace the process / terminate without
//! running Rust destructors. As written, v0.17 would silently emit
//! zero spans for every successful `secretenv run`.
//!
//! **v0.17 must add a pre-exec emission hook** — synchronously
//! flush whatever the v0.17 OTel exporter requires before the
//! `exec()` / `exit()` call. Concretely: in `runner::run_with_options`
//! and `runner::run_with_pipe_redaction`, just before the terminal
//! `exec_with_env(...)` / `std::process::exit(...)`, emit a
//! [`RunReport`]-equivalent span via the v0.17 telemetry sink and
//! flush. The `RunReport` returned to the dispatcher then becomes a
//! no-op for those paths; the other handlers continue to rely on
//! `Drop` emission.
//!
//! v0.14 `#[allow(dead_code)]`: every report field exists for
//! v0.17 emission (whether via `Drop` or pre-exec hook).
