ready() asked a gone instance for its snapshots before judge could say 'no longer
standing'; a stale warm.json from any earlier scenario made every warm run fail in
milliseconds. The question is now asked only of an instance that still exists.

The lab raised a `registry` VM, pushed ~73 images into it from the workstation, and
rewrote every manifest reference — third-party ones included — to point at it. No
production mesh has such a thing. So every bed proved that a machine could fetch an
image from a registry that exists nowhere else, and the bootstrap problems that only
appear when a machine has to fetch for itself went unfound.
What replaces it is the two things that are true in the world:
**Public images come from the public internet.** mesh-lab already created a NAT'd
uplink for exactly this and attached it to any machine declaring `egress`; no scenario
ever declared it. They do now, and third-party references are left exactly as the
catalogue writes them.
**The mesh's own images have no registry and never will.** mesh-control, mesh-builder,
mesh-route-proxy and the per-module runtimes are built from source and exist in no
registry. A machine gets them the way an operator's machine does — they are built here
and loaded onto it — and is then named by the digest of its own image configuration,
which mesh-host now accepts as "an image this machine already holds".
`images:` therefore means only *ours*, and a third-party entry is refused rather than
quietly loaded: otherwise the fiction returns one convenient line at a time. It is
per-machine as well, because "everything, everywhere" was never a description of
anything real — handing whole-mesh-full's union to its two 30GiB workstations would
fill the disk with runtimes nothing on them will start.
**The uplink and the declared gateway would have fought, silently.** A gateway container
and the transit router reach the scenario and nothing else; a default route through
either is a black hole for anything outside, and it beats the uplink's DHCP route on
metric. So a machine with egress states the scenario's ranges explicitly — through the
same gateway or transit it would have defaulted to, so the overlay-across-NAT path is
unchanged — and leaves the default to the uplink. A range with no path inside the
scenario becomes `unreachable` rather than falling through: 192.168.1.0/24 is an
ordinary private range in fact, and letting it escape would put scenario traffic on
whatever network the workstation is sitting on. `scenarioRoutesFor` is pure and tested,
because a decision only a full raise could check is one nobody checks.
The registry-reachability check the raise gained earlier is kept, pointed at the real
thing: every machine with egress must resolve a name and reach the internet before the
raise says it finished. Same failure it was written for — a raise that returns, an apply
that dies on its first pull, an instance left a bare shell — now guarding the path that
actually carries.
The base image's trust of the documentation ranges as plain-HTTP registries STAYS. It
was never only for the lab's registry: the mesh has one of its own, the `registry`
module, serving artifacts to the whole mesh over plain HTTP from whatever node runs it.

**The adoption.** Software nobody here wrote, taking its credentials the
way such software does — from its environment — and needing two
containers that reach each other by name. The first module that could
not have been declared this morning: it needs the network shape and it
needs a sealed value to reach a container's environment.
Its password is accepted rather than generated, which is the whole shape
of an adoption: a service that already exists keeps the credential it
already has. Asserted properly — a wrong password is refused by the same
database, so the passing case means something.
**The warm scenario.** A mesh kept between runs and returned to, which
turned twelve minutes of bootstrap into thirty seconds of restore. Off
unless asked for: a run that is meant to mean something raises from
nothing.
Its guard fired for real during this work, unprompted — a mesh-host
commit landed and it refused the stale base, naming both commits, rather
than passing tests against yesterday's binary. That is 04-ISSUES/005's
rule one level down.
Three things the guard learned the hard way and now handles: a snapshot
captures disk and not memory, so the host is restarted after a restore
and asserted to have come back; the stocked image digests are worked out
while raising and a restored instance never raises, so they are kept;
and comparing only the repositories this run can see clears the ones it
cannot, so both directions are compared.
The one real bug behind five failed attempts was in mesh-host and it
reported itself precisely: a network shape the language had and no host
implemented. Everything else was scaffolding of mine.
