The fleet dashboard kept raising conformance warnings. Genuine state edges were being amplified by four independent defects in how it observed and reported. Then two screenshots from my phone showed the first fix was incomplete.

Jobs were queuing behind a busy machine for no better reason than habit about which machine owned that kind of work, so I separated who runs a job from where the job lands.

A standing read-only collector that checks contract parity, machine-to-machine reachability, required services and timers, and required paths across the fleet. Three design choices carry it: it keeps last-known-good evidence, it separates drift from probe failure, and it never repairs anything.

I assumed every machine could reach every other. Checking every direction properly found a quarter of the paths broken, and one repair job reported success while having quietly undone itself.

I stopped doing my machines' work at the keyboard and built a way to hand a task to whichever machine should run it, let it run on its own, and pick up the result later.

Turned the fleet into a full mesh where every machine can reach every other one directly, passwordless, without hand-managed keys, laying the groundwork for running work anywhere in the fleet.
