name	eco-link-claims-to-observations
description	Link claim-side evidence objects to observation-side evidence objects, score support or contradiction heuristically, and persist a compact claim-observation link artifact for board review and challenge work.

Eco Link Claims To Observations

Core Goal

• Read claim-side and observation-side candidate or grouped result sets from the analysis plane, with artifact-compatible fallback behavior.
• Propose support, contradiction, or contextual links between them.
• Persist a link artifact for board review, challenge work, and later promotion gates.

Triggering Conditions

• Need claim-to-observation evidence hypotheses instead of isolated candidate lists.
• Need a compact link layer before board, challenge, or promotion skills.
• Need stable link ids, rule traces, and provenance refs for auditability.

Read/Write Contract

• Loads claim-cluster result sets from the analysis plane first and falls back to claim-candidate results only when the preferred claim-side grouping is missing.
• Loads merged-observation result sets from the analysis plane first and falls back to observation-candidate results only when the preferred observation-side grouping is missing.
• Uses claim_candidate_clusters_<round_id>.json, claim_candidates_<round_id>.json, merged_observation_candidates_<round_id>.json, and observation_candidates_<round_id>.json as the default artifact paths behind those result kinds.
• Writes runs/<run_id>/analytics/claim_observation_links_<round_id>.json by default.
• Syncs the same link result set into runs/<run_id>/analytics/signal_plane.sqlite as analysis-plane state.
