Switches the default --trace from outputs/inferact_50sess.jsonl (median 63K, p99 143K, 1285 reqs) to third_party/traces/qwen35-swebench-50sess.jsonl (median 27K, p99 92K, 4449 reqs across 52 sessions). Smaller per-request inputs let us check whether the queue-induced TTFT collapse the user flagged is workload-specific. Total trace is 3.5x larger so the run will cover more turns per session.

# E4-pressured — same as E4 but tuned to force admission rejections so the
|
|
# D→P snapshot fast-path actually fires.
|
|
#
|
|
# Key delta vs sweep_e4_kvc_v2_d_to_p_sync.sh:
|
|
# --kvcache-migration-reject-threshold 1 (was 3)
|
|
# After ONE rejection the policy migrates the session to a different
|
|
# D, which in turn triggers _invoke_kvcache_seeded_router → D→P sync.
|
|
# --decode-mem-fraction-static 0.4
|
|
# Plumbed through cli.py → topology.decode_extra_server_args →
|
|
# launcher. Shrinks per-decode KV pool, forcing admit_direct_append
|
|
# to reject more often.
|
|
#
|
|
# Hypotheses (same as docs/E4_PROTOCOL_ZH.md but in a stressed regime):
|
|
# H1' E4-pressured TTFT p99 ≤ E1 TTFT p99
|
|
# H2' D→P snapshot succeeds for ≥ 20% of reseed-triggering requests
|
|
# H3' D→P-pushed-then-cache-hit reduces re-prefill segment of reseed
|
|
# path TTFT measurably
