# Contribution Weights
#
# Global policy for how much each contributor role counts toward weighted scores.
# Used by the build pipeline to compute weighted_score in contributors.json
# and Contribution Index (CI) in reward-mechanism.md.
# Updated via PR — changes here affect all contributor profiles.
#
# Weights sum to 1.0. The build pipeline multiplies each contributor's role count
# by the corresponding weight, then sums across roles.
#
# Current rationale (2026-03-14, revised from Rio's mechanism design brief):
# - Sourcer = Extractor = Challenger at 0.25 each. This signals that finding
#   the right source with a clear rationale, turning it into a structured claim,
#   and challenging existing claims are equally valuable acts. Equal weighting
#   prevents agent CI domination during bootstrap (agents fill extractor role,
#   humans fill sourcer and challenger roles).
# - Synthesis connects claims across domains — high value but rare.
# - Review is essential but partially automated via the eval pipeline.
#
# Review after 6 months of data. If sourcer contributions turn out to be
# low-effort, the weight is too high. If challengers produce disproportionate
# belief changes, the weight is too low. Weights are policy, not physics.
