# Superseded evaluation run — 2026-07-22, Claude Opus 4.8

rubric20_semantic evaluations of claudecode_agent (full D4D) and claudecode_agent_core (D4D-core)
outputs for AI_READI, CHORUS, CM4AI, VOICE, run 2026-07-22 with Claude Opus 4.8
(operator-confirmed session model; see run_manifest_2026-07-22_opus-4.8.json at
the evaluation_llm root).

NOTE on model stamps: the "model.name" field inside these JSONs reads
"claude-sonnet-4-5-20250929" — that string came from the rubric agents' output
template (the same files contain literal "sha256-placeholder" values), not from
runtime introspection. The actual judge model was Claude Opus 4.8.

Superseded the same day by the claude-fable-5 exemplar run whose results live at
the top level of this concatenated/ directory.
