# dispatch_check.sh — the session agent's pre-spawn discipline.
#
# Run this before spawning ANY wave. It reads the brief file, asks the
# dispatch-classifier for the verdict, and prints it. Follow it:
#   SOLO            spawn one agent, full attention
#   PARALLEL        spawn one lane per suggested split surface
#   QUEUE-BEHIND    do NOT spawn onto those surfaces yet
#   PRIORITY-QUEUE  owner wave: the lock-holder yields at its next
#                   landing boundary; wait for it, then go
#
# Usage:
#   scripts/dispatch_check.sh <brief-file> [--paths p1,p2] [--owner-origin]
#   scripts/dispatch_check.sh <brief-file> --apply [--agent X]
#
# --apply takes the lock for you (fails loud if anything is locked or
# stale — prune with `dispatch-classifier show --prune`). Every exit 0
# prints the verdict JSON on stdout; exit 1 means do not spawn.
