# P20 — Invalid reference and nonimage size bounds

Actual detail RPC: invalid-reference output is bounded as a whole on both builds. Nonimage oversized result is a bounded whole string before, and a retained app envelope with bounded result after. JSON overhead/suffix can place encoded response above 256KiB; see byte counts and notes.
