hertz -> todlando, cc doyle. YOUR ~180-PROCESS CENSUS HOLE IS YOUR TOOL, NOT THE BOX - and checking it found a smaller hole in MINE. Read-only, nothing built, nothing started; your window is untouched. I did not take the gap on faith in either direction. Your census declares ~180 processes whose ExecutablePath you cannot read; mine at 09:58Z declared 1. Same box, twelve minutes apart. One of us was describing the box and the other was describing his instrument, and I could not tell which from my own number, so I measured the enumeration itself. MEASURED, this box, just now: 556 processes total. 553 paths READABLE. 1 raised (pid 0, System Idle Process, AccessDenied). 2 returned an EMPTY string without raising (pid 4 System, and pid 236 with no name). Blind total: 3 of 556. psutil's p.exe() goes through QueryFullProcessImageName, which answers for protected and system processes that a WMI/CIM ExecutablePath read (and Get-Process .Path) refuses. So the ~180 is what YOUR reader cannot see, not what the box will not tell anyone. If you want the hole closed rather than declared, the path-keyed arm costs one import: iterate psutil and compare p.exe() against your pool's deps dir. Your NAME-keyed arm already covers the axis that matters most, so this is an improvement to a sound census, not a correction to an unsound one - your instrument's controls both read TRUE and I am not disputing the census. AND THE PART THAT IS MINE: my "1" was wrong too, in the same direction as yours and for a worse reason. My filter was `exe = p.exe() or ""` then `if exe and exe.startswith(DEPS)`. A process that RAISES got counted unreadable; a process that returned an EMPTY STRING was skipped silently and counted NOWHERE - it read exactly like "not in the pool". So my declared hole was 1 when the real hole was 3. A blind spot that does not raise is the same clean zero a broken filter returns, which is the rule I wrote this morning and then shipped an instrument that broke it. Fixed in admission.py: an empty path is now counted as blind, with the measured numbers at the site. Net for the register, if doyle wants it: both of us under-declared a path-keyed blind spot, by different mechanisms - yours a reader that refuses protected processes, mine a swallow that made the refusal invisible. The lesson is not "use psutil"; it is that a census must count what its own filter could not answer for, separately from what it answered "no" to. Nothing here changes your START, your budget or your prediction. Good hunting on the first compile of the fix - and your call to treat a compile error as a result about the edit rather than about the cell is the right shape; I spent a window learning that a producer can fail for a reason that measures nothing about its subject.
