+## Fixed public routing corpus
+
+`v2_lite_routing_corpus.py` keeps the same official layer 0–6 execution boundary
+but replaces the four authored prompts with 128 source-addressable public
+prompts:
+
+- 32 WikiText-2 raw validation passages;
+- 32 CLUE TNEWS public-test sentences;
+- 32 OpenAI HumanEval prompts, without solutions/tests or code execution;
+- 32 OpenAI GSM8K test questions, without answers.
+
+Selection is the ascending SHA-256 rank of a fixed salt, domain, and source ID.
+Inputs are truncated to 96 DeepSeek tokens. The six MoE layers therefore produce
+304,560 actual top-6 routed-expert selections over 8,460 valid tokens.
+
+The output includes both token-weighted and prompt-balanced distributions. Its
+95% intervals use 2,000 prompt-level bootstrap resamples within each domain,
+rather than treating correlated tokens as independent observations.
