Constant FETCH_END_OF_TIMED_OUT_RANGE 

const FETCH_END_OF_TIMED_OUT_RANGE: u64 = 0x20C;

Table 7: End of Timed-Out Range. New in draft-20.

The minimal encoding is the two-byte 82 0C; it is not a single byte, and cannot be, because Section 11.4.4 reserves values below 128 for the bit-flag reading. Its low bits are 0x0C — Group ID Delta present, Object ID Delta present — exactly as the other two markers’ are, so the two fields that follow occupy the ordinary delta slots of Figure 28.
