about

nx_ch_census_oracle.nx -- per-assignment ORACLE STAGER for the CH-census race under the generic referee (nx_race_referee). Composes the TEAM's own pieces: _pe_chwalk (STRUCT_WALK- authored) locates the extension block of the real emitted ClientHello; the SHIPPED tls13_ext_find supplies ground-truth offsets (it predates every lane = neutral). Writes: /tmp/race_block.bin /tmp/race_trunc.bin /tmp/race_empty.bin the three case inputs /tmp/race_manifest.txt lanes + cases + 12 rows with oracle wants /tmp/race_manifest_tampered.txt same but row 1's want is +1 -- staging THIS manifest must turn the referee RED (proves the harness can fail) A NEW assignment = a new oracle stager like this one + the same referee. license_tier: ORIGINAL
