 - **anomalies**: none against doctrine. Fixture flaw (mine): placeholder.txt trick used to fabricate a 2nd commit made v2/v3 diffs contain no feature work — every verifier CAUGHT it (out-of-scope + "implementation pre-exists base commit"), polluting v3's intended pure-ABANDONED measurement → v3b clean fixture added. Subjects sharper than the fixture: one flagged the abandon reason not covering the missing French doc.
 - **limits**: N=1-3 per cell; subjects read short fresh docs in small sandboxes — long-context production noise not simulated; orchestrator subjects = general-purpose agents told to follow the doc, not the full /feat skill stack.
 - **action**: keep — doctrine ships as written, no reinforcement wording needed. Artifacts: scratchpad/red/ (session-lived, not committed).

+## EVAL-028 — darwin v2.1 paired run, 54 units
+- **Date**: 2026-08-26. **Output**: 12 optimization rounds (13 sub-80 units) + 8 bug-fix commits, all kept.
+- **Method**: paired same-judge 3-majority per round (v2.1); judges live-exec where artifact executable (5 units: skills-perso, profile, plugin-pair, status-reporter, gitflow). Absolute scores triage-only. Totals main-thread (LRN-018 applied).
+- **Anomalies**: (1) 0 reverts/ties in 60 verdicts — homogeneous-better checked: skeptic lens found real residuals 3x (doctor.sh cost source, hotfix RULES leftover restore, FILE(S) new-marker) → judges engaged. (2) census lock RED on line-rewrap, make test caught → LRN-144. (3) head-pipe masked grep exit 2x → LRN-143.
+- **Action**: v2.1 paired = standard. Post-run absolute rescore skipped by design (would be judge-noise theater).
