P144 removes the second repair word from execute-stage prefetch fills. The first adjacent repair word remains, and the per-class classifier from P143 stays active.
The shell workload passes and reaches P144-FILE-OK.
This cut background repair fills by 10,014,827 versus P143 and recovered 563,987 shell-window cycles. It still trails P142 by 266,142 cycles, so the class-wide throttle is too blunt.
The next step should make execute-prefetch second-word repair conditional instead of globally off.
