# archeflow-decision.sh — Log a PDCA decision point for run replay / effectiveness analysis.
#
# Appends a decision.point event to .archeflow/events/<run_id>.jsonl with:
#   phase, archetype (agent + data.archetype), input, decision, confidence, ts (via event layer)
#
# Usage:
#   ./lib/archeflow-decision.sh <run_id> <phase> <archetype> '<input>' '<decision>' <confidence> [parent_seq]
#
# Examples:
#   ./lib/archeflow-decision.sh 2026-04-06-auth check guardian \
#     'diff + proposal risks' 'needs_changes' 0.82 7
#   ./lib/archeflow-decision.sh 2026-04-06-auth act "" 'route findings' 'send_to_maker' 0.9
#
# confidence: 0.0–1.0 (orchestrator-estimated certainty in the recorded choice)
#
# Requires: jq (via archeflow-event.sh)
