Mirror of PublicUpdatePropertyInt (0x02CE) but with no guid field — targets the local player's own object. Burden (EncumbranceVal, PropertyInt 5) changes ride this opcode on every pick-up / drop. Layout: opcode(4) + seq(1) + property(4) + value(4) = 13 bytes. 3 tests: happy path, wrong opcode, truncated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
