r507a op-failure latch is time-based: a full opdef window before it stops holding (r507 matmul lost a pin-late 1 MB UVA copy and verified FAIL)
r506w's attempt-count latch tripped after 8 fast passes (~100 ms) while
the legitimate pin-late retry needs 0.5-2 s (r507 witness: memcopy
dst=0x71365ee02200 src=0x71365e500000 bytes=1048576 rc=-2 skipped; matmul
completed with STATUS FAIL instead of hang). The first failure of a VA now
arms a full 10000 ms window during which the op holds its entry exactly as
before; only after a full bound with no success does the op stop forcing
the hold. A success clears the record (fresh window on a later failure).
