Test sends a 4-byte payload b'xce!' via wire.send_frame() over a real TLS socket to a raw capture handler that reads exactly 12 bytes (8-byte length header + 4-byte payload) directly off the wire, bypassing this module's own recv_frame() decoder. Expected the captured bytes to be struct.pack('=Q', 4) + b'xce!' (header correctly encodes length=4, followed by the literal payload bytes). Actual captured bytes: the 8-byte header is correct (b'\\x04\\x00\\x00\\x00\\x00\\x00\\x00\\x00', i.e. length=4 little-endian native uint64_t), but the trailing 4 bytes are all zero (b'\\x00\\x00\\x00\\x00') instead of b'xce!' -- the real payload bytes never reached the wire. 1 failed, 266 passed, 3 skipped -- isolated to this one test.",
+      "file": "src/xceadmin/src/xcecommon/wire.py",
+      "root_cause": "Not yet root-caused. The correct length header (4) but zeroed payload bytes on a real TLS stream (not a test-harness artifact -- TCP/TLS doesn't spontaneously inject zero bytes) points at send_frame() itself writing/allocating a zeroed buffer for the payload portion of the frame instead of copying in the actual argument bytes -- candidates: an off-by-one or wrong-source-buffer bug in how the header and payload are concatenated/written (e.g. writing len(payload) zero bytes from an uninitialized bytearray instead of the payload argument, or a struct.pack/memoryview slicing bug that addresses the wrong buffer). Needs a direct read of send_frame()'s implementation to confirm.",
