+# Main-Claim Allowed Runs
+
+Status: current audit gate
+Date: 2026-05-25
+
+## Allowed For Workload-Shape Claims
+
+These artifacts can support trace/workload characterization claims:
+
+- `dash0:/home/admin/cpfs/wjh/ali-trace/trace-glm5.1-formatted/051315-051317.jsonl`
+  - Compact formatted full trace.
+  - CPU summary recorded in `full_trace_summary.json`.
+  - Supports long-input/short-output and session token-mass skew claims.
+  - Does not prove runtime cache hits or online sequentiality.
+- `traces/w600_r0.0015_st30.jsonl`
+  - Local sampled trace.
+  - Useful for local dry runs and figure generation.
+  - Not the canonical full-trace source.
+
+## Allowed For Legacy Baseline Sanity Claims
+
+These existing runs can support sanity-level comparisons, but not final
+paper-grade SRR claims:
+
+- `outputs/gpu_ab_combined`
+- `outputs/gpu_ab_pdsep`
+- `outputs/contention_16s_ts10`
+- `outputs/contention_16s_elastic`
+- `outputs/combined_1000req`
+- `outputs/exp3_pd_sep_tp1_mooncake`
+
+Allowed claims:
+
+- Static PD-sep was worse than combined in these existing fixed-request runs.
+- Elastic transfer-based migration did not improve the summarized 500-request
+  high-contention run.
+- GPU-util imbalance exists in these artifacts.
+
+Disallowed claims:
+
+- Online SRR.
+- Per-session sequentiality.
+- Causal attribution of prefill/decode interference.
+- Causal attribution of session hot spots from GPU utilization alone.
+
+## Not Yet Allowed For Main Claims
+
+The following need fresh instrumentation or fresh runs:
+
+- Batch 2 prefill/decode interference.
+- Batch 3 session hot-spot root cause.
+- Batch 4 sustainable request rate.
+- Batch 5 failure attribution near SRR boundary.
+
+## Required Upgrade Before Paper-Grade Claims
+
+Future main-claim runs must include:
+
+- per-request actual dispatch timestamp;
+- per-request finish/error timestamp;
+- route decision and selected worker;
+- per-worker queue delay;
+- per-worker KV occupancy;
+- per-worker APC/cache-hit snapshot;
+- attempted/completed/error/goodput counters;
+- session-causal load generation.
