  # --- All possible trigger fields (an event sets only the ones it uses) ---
  # tokens: <int>                 flat token-count threshold (session-wide measurement)
  # ctxWindowFraction: <float>    fraction of the model's context window, e.g. 0.75 = 75% full
  # tokensSinceCheckpoint: <int>  tokens accumulated since the last fold checkpoint
  # minTurns: <int>               gate: never fire before this many turns exist (token events only)
  # rounds: <int>                 round/repeat-count threshold (stuck-loop/task/judge/handshake events)
  # bytes: <int>                  byte-length threshold (truncation-cluster events)
  # distinctCalls: <int>          distinct-call-count threshold (web/bash/file/code call-budget events)

  # Total estimated size of the in-flight message array during a single
  # turn's tool loop. Past this, the oldest complete tool round-trips are
  # dropped so a long loop does not re-send an ever-growing transcript on
  # every round.

# run: selects the action fired once the trigger above is met.
# Valid actions (assets/actions/*.yaml -- override at ~/.kdeps/actions/*.yaml):
#   compact         summarize older history into a checkpoint
#   truncate        shorten oversized content to a budget, marking what was cut
#   reject          refuse an operation that exceeds a size limit
#   block           refuse further distinct tool calls once a budget is spent
#   drop_oldest     drop the oldest entries from a growing collection
#   cap             bound a collection to a fixed count while building it
#   force_answer    end the tool loop and force a final text answer
#   fail_task       escalate and eventually close a stalled goal-directed task
#   fail_handshake  end a session-integrity handshake challenge as failed
#   accept_last     accept the last judge-panel response once the budget is spent
