// Regression test for #2220: headless mempalace-capture instructed
// `mempalace mine <path> --wing <wing> --room <room>`, but `mine` has no
// --room flag (only `search` does). The fix replaced the flag with a
// detect_room()-based staging approach.
//
// #2414 extension: the staging block also embeds a `rooms:` YAML example.
// mempalace's miner (`detect_room()` and `_mine_impl`) requires each entry
// to be a DICT with at least a `name` key — a bare-string list crashes the
// first `mine` invocation with `TypeError: string indices must be integers,
// not 'str'`. The fix converts each `- <room>` to `- name: <room>`.

// js-yaml, and asserts every entry under `rooms:` is a dict carrying a `name`
// key. It also forbids the pre-fix shape (`- decisions` etc.) so a future
// reversion can't slip back in silently.
