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.

(Phase 1 of the wall-clock amplification measurement plan; needed for
§2.3 dispatch coupling empirical closure)
- figs/: 8 reusable figures copied from analysis/ with paper-spec names
(f2a/b/c workload, f4a/b/c/d failure modes, f6 e2e partial)
- PAPER_OUTLINE.md: real figure paths, explicit TBD markers for
custom drawings and pending data; new "Validation Status" table at top
and reorganized "Work Plan" splitting can-do-now vs migration-deferred
Migration validation deferred per user: 4 prior attempts (6b255fa,
e991960/5772149, cc6e562, 4c583f2) were reverted due to transfer
overhead; pending re-test on top of connector_tax DR-fix.
