The previous f2b_session_skew.png was a 3-bar chart (top 1/5/10%) computed from the production trace summary (which is not present locally, only its precomputed JSON). The new figure is a continuous CDF of cumulative input-token mass vs session rank percentile, generated directly from the replay trace traces/w600_r0.0015_st30.jsonl so any percentile is readable. Headline numbers update accordingly: replay trace (n=274 sessions): top 1% = 24.3%, top 5% = 61.9%, top 10% = 75.8% production trace (n=1.3M): top 1% = 46.5%, top 5% = 66.5%, top 10% = 74.6% Both show extreme skew well above the y=x uniform reference; the replay trace is less extreme at top-1% because n=274 makes that bucket only ~3 sessions. We standardize §2/§3 narrative on the replay-trace numbers so motivation matches §5 evaluation; production numbers kept as a side note for context. - scripts/plot_session_skew_cdf.py: reproducible figure generator - MEETING.md / PAPER_OUTLINE.md: update narrative + caption Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
