# E40 §6 Process Job state model — encoded as a transition table.
#
# Each row is a (from, on) -> (to [, ack]) tuple, mirroring the encoding
# in data/control_state.yaml.  Events are the lower-snake-case verbs the
# loader maps to ProcessJobEvent: start / pause / resume / stop / abort /
# hoq / select / setup_complete / process_complete / abort_complete /
# created.  Host-initiated events (start, pause, resume, stop, abort,
# hoq) carry an `ack` when the row should override the default
# HostCmdAck::Accept (e.g. a row that only validates an event without
# changing state).
#
# Wire reference: S16F9 PRJOBSTATE byte (E40-0705 §10.3.2):
#   0 Queued, 1 SettingUp, 2 WaitingForStart, 3 Processing,
#   4 ProcessComplete, 5 Paused, 6 Stopping, 7 Aborting.
#
# Process-Complete is terminal — deletion happens out-of-band via the
# ProcessJobStore (CJ cleanup or explicit S16F13 while still QUEUED).

transitions:
  # --- QUEUED ----------------------------------------------------------
  # PJSTOP/PJABORT on a Queued PJ routes through Aborting so the host
  # observes PRJOBSTATE=7 on the wire (E40-0705 §6.3). PJDELETE / S16F13
  # is the dequeue-without-state-change path.
