ADR 0145: a module checks what the mesh claims is reachable, and it checks itself 9de25994e9

The mesh asserts three things are callable and has never checked any of them. A
module on every machine serves an endpoint of its own and dials every other
machine's, from the position the callers are in — not the host and not the control
plane, both of which reach those addresses by paths no ordinary caller uses and
would have passed throughout the outage.

Its probe is its own endpoint, declared reachable over the private network, so it
is admitted by exactly the rule that governs every internally-exposed service. The
tempting target is a service every machine has, and those are the ones never closed
— ssh above all — which would have passed for all eleven hours.

Resolution and connection reported separately, because they have different owners.
One failure is not a fault, and the count travels with the result. It reports and
repairs nothing.

Built on a scheduled container, a rendered roster fact and a bundle: no new
vocabulary. Adopted on its own merits, which is what 0143 was not.
