# Per-pattern trajectory rules — TRACE v1
# Parameters that drive per-session accuracy and behavior-frequency generation.
# Each pattern ID matches configs/session_interpretation/taxonomy.yaml.
#
# Interpretation of fields:
#   base_range: uniform-sample initial accuracy
#   delta_per_session_range: per-session delta applied cumulatively
#   noise: uniform ±noise added per session
#   behavior_trajectory: how target-behavior frequencies evolve (optional)
#     "stable_low" / "ascending" / "descending" / "spike" / etc.
