Several adversarial probes exceeded their time bounds in the merge41 run (Mail toast, PDF thumbnail, dedup/archive, Notes preview), and the user-purge upload p95 was 4.353 s against a 2 s target. Find out which are slow product paths and which are probe bounds; fix real slowness (perf VM measurements), fix probes otherwise. Dedup phase 'attention' matches DESIGN §5: update the probe, not the product.

Found by the merge round 41 adversarial run (branch job/merge41 adf8205c9; log artifacts/merge41-gates/adversarial-final.log in worktree /home/kayg/Developer/calternal-wt/merge41, report on #1573). Not a merge blocker under the CLAUDE.md rule. Owner of the fix: confirm whether it also happens on production c0f8da461, fix with a regression test in tests/adversarial.
