Codex Panel A/B (contributor instrument — verdict decided)

Answer one question with evidence: do dimension-focused codex passes find real issues that one holistic codex exec review misses? Runs both on the same diff, then classifies every focused finding against the holistic pass.

DECIDED 2026-07-10 after 4 runs (2 fresh): panel KILLED. Fresh-only 1 real miss / 1 false positive plus one zero-value run at 4× cost — real misses did not outnumber FPs. Kept as contributor tooling (NOT distributed) for one possible retest: a UI-heavy diff with a single extra liveview-focused pass (2× cost). Scoreboard: .claude/research/2026-07-03-codex-review-integration.md §7.
