- replayer/replay.py: emit trace_span_s and amplification in summary
(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.

Initial 8-section outline for "Elastic Affinity Router" — agentic LLM
scheduler with session-affinity routing + hot-triggered session migration.
Centerpiece is §2.3's dispatch coupling argument: agentic workloads close
Little's Law on themselves (no human think-time), so per-turn W enters Λ,
amplifying small latency differences into throughput differences. This is
the intellectual hook the design hangs on.
§3 attacks three baselines on three orthogonal failure modes (load-balance
loses locality, static PD-disagg hits D-side KV wall, pure sticky creates
hot pin). §4 frames EAR as the single scheduler that addresses all three.
All figures and several numbers (T_hot, T_cool, EAR wall-clock factor) are
TBD — see Open Items at bottom.
