 "trial": "Re-verification of load-bearing figures against Claude Code 2.1.227",
 "date": "2026-08-11",
 "version": "2.1.227 (Claude Code)",
 "method": "Every arm measured against its OWN floor in the SAME round, because the session baseline drifts ~290 tokens and cross-round pairing has produced bogus deltas before. No --setting-sources isolation: the published figures are paired deltas taken with the user-level CLAUDE.md loaded in both arms where it cancels, and isolating would shift the baseline ~21,000 tokens and break comparability.",
 "caveat": "The 28,000-byte filler used here is not the text used for the original measurement. Token density depends on content, so the numerators are not strictly comparable across runs. The mechanism and order of magnitude are what this re-verifies.",
