gc-ratchet: re-pin baseline on the dedicated bench host (ratchets #7443's retention win) - #7446
Merged
Conversation
…tention win Captured on the new pinned quiet host (Mac mini M1, 8 GB, Spotlight disabled, cpu_active 4-7% at capture) at main 5e236e6. Locks 12_large_live_set's heap_used at 59.9 MB — under the previous 105.6 MB pin, a regression back to unreclaimable scattered-survivor retention would have PASSED the increase-direction band. Counter families are unchanged from the previous pin (0% spread across 7 repeats); memory and wall medians re-baseline on the dedicated host, whose observed wall spread (~1-2%) is far inside the pinned_host bands.

One-file baseline update, measured on the new dedicated pinned quiet host (
