  • Closed#14894[Bug]: post_llm_call response overrides are applied after persistence, causing final_response/history mismatch
  • Closed#44239[Bug]: transform_llm_output and post_llm_call hooks both produce final_response/history mismatch — same root cause as #14894
How this cluster was grouped
  • Link evidence (partly structural links): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
  • Members outside that structural core may belong to a different underlying problem.
  • Pairwise link density 0.12: the share of item pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. 1.00 means every pair is linked.
