pub fn brief(repo: &Path, limit: Option<usize>) -> ExitCodeExpand description
Boot-read: the live user-ruled decisions and the roads they rejected. A near-zero-cost, 0-network read (read_all only; no git, no receipts) for a fresh agent to load the decisions it must respect and the options it must not re-propose. Load-bearing rulings (those that closed a road) sort FIRST — pinned above the cap regardless of recency — then by recency (held_since), then id. Capped to the effective limit, with a remainder footer that counts how many hidden rulings closed a road so the elision stays visible.
