A standard iteration paid a dedicated ~37k-real-token dispatch for a
clean-tree check. The check itself stays deterministic in the script:
plan-index now carries clean/head_sha/branch/dirty_paths (run FIRST,
before reading the plan; a dirty tree returns an empty index), and the
script evaluates the folded verdict before any cardinality guard. Mini
mode keeps its dedicated preflight — it has no plan-index to fold into.
