Extended deterministic test to write serialized evidence record to
OS temp directory, read back from disk, parse JSON, and assert deep
structural equality. Verified: five structured arrays preserved with
correct lengths; exact inputs unchanged; identity fields intact; null
metadata fields survive round-trip. Temp file cleaned in finally block.
Zero live model calls. Zero browser calls. No production code or
canonical-helper modifications. Experiment 4 original structured
output remains unavailable.
