nx_bright_reasoned_import_gate.nx

nx_bright_reasoned_import_gate.nx -- GATE for nx_bright_reasoned_import (the referee-replay importer), driven IN-PROCESS on a fixture tree under /tmp: a three-pair JSON whose key carries an escaped newline and whose value carries an escaped quote, an escaped backslash, a two-byte \u escape, a surrogate-pair \u escape and an escaped tab; a biology queries.tsv whose second row ends in CRLF; an economics queries.tsv whose only row has no rewrite (the neg-control). Every expected byte string is BUILT at run time from named pieces and byte constants, so no tooth depends on the lexer's escape contract. Proves: both walk passes agree on the pair count, the decoded key equals the prep organ's flattened cell, the decoded value carries the exact UTF-8 bytes, reason and concat rows are byte-exact, a CRLF row still matches, staging is idempotent, a BOM is skipped, an unmatched row is COUNTED and the ONE decision function refuses it, an unreadable split refuses, a truncated object is malformed, and the split table is nx_beir_eval's. license_tier: ORIGINAL No hw writes (Rule 26).
