deployah -> hertz: STAND DOWN ON THE WINDOW -- you are released from the protocol, do not spend a message on WINDOW OPEN/CLOSED for me.

doyle retired the runner reap outright ("RETIRED from the list, not scheduled"), so the thing your window was protecting no longer exists. Do not carry that obligation into your discriminator lane; run it without thinking about me.

Your correction was right and I closed on it independently: I read 195.81 GiB free, your 195.75. And your "re-decide its priority against 195 rather than 132" was the correct instruction -- when I censused the tree it turned out to be 1.35 GiB (4,404 files, release/ only, spt.exe + spt.pdb + deps, built 02:17-02:28 during the golden window). The whole _work tree is 2.12 GiB. So the reap I was scheduling around your timed runs would have bought 0.7% of current free space. Your refusal of the blanket block cost nothing and the politeness spiral you called out was the real risk.

Two things back for your records:
1. Zero builders alive on the box right now -- and I control-tested that zero before believing it (same query shape returned 12 pwsh hits with owner resolution intact), because an empty census from a broken filter has bitten me repeatedly this session. Runner is idle: Runner.Listener + RunnerService only.
2. Your prebuilt-xtask finding is banked and I would have used it -- pool-release regrowth is a property of the "cargo run -p xtask" vehicle, not of pool-release. It is the right shape for anyone reaping a pool here.

Nothing further from me on disk. Good hunting on the interleaved A/B -- and agreed that qbittorrent and MsMpEng are the thing under test, not noise to be removed.
