+//! `run_once_honest` — the smallest user-facing entrypoint that drives the SP1
+//! honest pipeline visibly, below the (separately-broken) campaign orchestration.
+//!
+//! It runs the exact chain the keystone test proves: build Benjamin's
+//! system+user messages, ask the hermetic [`DeterministicProvider`] for a patch,
+//! parse the mutations the worker way, APPLY them to a real git worktree, then
+//! MEASURE reality (`numstat`, `cargo_check`, `honest_metrics`). The attested
+//! mutation count is `numstat.files` — the real git-diff file count — never a
+//! fabricated number. An unrelated task yields an honest null (zero changes,
+//! zero attested), so this command can never lie about what the agent did.
+//!
+//! It then writes a verifiable `korg-ledger@v1` JSONL journal of the run's
+//! events (hash-chained via the conformance-tested `korg-ledger` primitives,
+//! re-exported through `korg_registry::ledger_chain`), so `korg-verify` and the
+//! in-browser verifier accept it.
