nx_ch_census_race_stage.nx

nx_ch_census_race_stage.nx -- NEUTRAL input stager for the CH-census autonomy race (operator: "have the team do an assignment and you do it and see where they can grow to match or exceed you"). Emits the browser's REAL ClientHello (nx_tls13_client_session_emit_ch, deterministic), locates the extension block, and stages THREE race inputs both lanes consume identically: /tmp/race_block.bin the real extension block (the assignment's live data) /tmp/race_trunc.bin the same block cut 3 bytes short (mid-entry truncation) /tmp/race_empty.bin zero bytes (empty extension list) This stager is RACE INFRASTRUCTURE, not a lane: both lanes get byte-identical inputs, so neither lane's author touches the other's data path. license_tier: ORIGINAL
