about
nx_cms_api_exceed_gate.nx -- W-RE-004 head-to-head EXCEED (rest-graphql-api, INJECTION-SAFETY axis).
Runs BOTH serializers on the SAME corpus of field values (benign + quote-injection):
OURS = cms_api_render_obj (nx_json_emit, RFC 8259 escaping)
INCUMBENT = naive string-concat JSON (no escaping) -- the CWE-116 failure mode (improper output
neutralization -> JSON injection / structure breakout).
A serialization is CORRECT iff the output stays well-formed: exactly the expected number of UNESCAPED
double-quotes (4 for one key+value object). A value containing a `"` breaks the naive concat (extra
unescaped quotes) but ours escapes it. Verdict COMPUTED by nx_cms_exceed. license_tier: ORIGINAL
