/**
* Snapshot suite for the plan-mode composition (`../cordis.yml`, swapped to
* the sibling `cordis.snapshot.yml` replay overlay by the bin under
* `DSH_SNAPSHOT=replay`).
*
* The recorded scenarios re-execute the fs tools AND the sandboxed bash
* executor for real on replay (the replay overlay swaps only the model): the
* recorded `cat` runs under the host's actual runner (Seatbelt on macOS,
* bwrap on Linux CI), under the sandbox's own configured mode — plan mode
* does not change it. The recorded commands stay `cat`-shaped —
* byte-identical across those backends and across GNU/BSD userlands — and
* the transcripts carry NO sandbox denial (a denied command's stderr is the
* backend's dialect; the denial→marker path is pinned at dsh-tool-bash's
* unit tier). Prompts pin the model to RELATIVE paths, because a recorded
* absolute temp path would neither replay on another host nor normalize
* (the normalizers scrub the RUN's own cwd, not the recording's).

// initial) — the full toolset plus exit_plan_mode and the mode section —

// a pure removal the delta encoding CAN express (one header-delta; the
// ENTERING flip is a non-tail insertion the append-only tools delta cannot
// express, so it falls back to a snapshot — pinned at the unit tier). The

// presents the plan via exit_plan_mode → the scripted elicitation approves
// → the very next step already edits for real, mid-turn.
