> **Progressive insight — 2026-10-02.** The decision stands; these are the facts of its building.
Built across mesh-host 63 and 64 and mesh-controller 201, 202 and the pull request that followed
them. Rule 1: `take` previews every held thing's comparison and ends with a digest; `take --yes
<digest>` acts on exactly that preview, and a changed preview or an account older than the flip
allows is refused, as the flip's are. A published port's reach is said as the machine reported it,
behind the found firewall whose rules are not read. Rule 2: an older image, a differing file and a
minted, unaccepted secret for found data refuse, overridden by `--downgrade`, `--replace <path>` and
`--mint <name>`; the secrets a module holds on a machine are read with where each came from. Rule 3:
`secret accept --provider` reaches a required secret. Rule 4: the per-machine setting is `networks`,
a container id to the found networks it keeps; judged for an adopted machine only, joined by the host
after the container runs, part of the container's spec, named in the preview. Rule 5: the host's
facts, former targets and strays. Rule 6: one judgement, run where a setting is stored and where a
machine is composed; a module whose stored setting its definition can no longer compose is left out
of the declaration, the envelope says so, the host keeps that module's things, and `plan` and `push`
say it by name. A key that reaches nothing is refused where stored and said by `plan`, and never
costs a module. Rule 7: genesis raises the forge under the module's container name, with its image
digest and its data directory; the network is the one difference left, said by the take, because the
bootstrap forge reaches the store on the machine's loopback.
**Not yet proven live.** Every machine of this mesh is converged, so the table's last row — a take
on an adopted machine — waits for the next adoption. What is live is what the rows above it check.
Issues 086, 098, 099, 100 and 101 stay located until that row is read.

container's spec, refused when it cannot be joined. A declaration may name the modules the mesh left
out of it because a stored setting cannot compose with the module's definition: the host keeps what it
wrote and holds for a left-out module and says so, where absence used to read as removal. And genesis
raises the bootstrap forge under the forge module's container name, with the module's image digest and
its data directory, so the module holds it by the found rule; the network is the one difference a take

**A setting is judged where it is stored, and the take's words** — revision, 2026-10-02
([ADR 0163](../../02-DECISIONS/0163-taking-a-module-over-is-a-comparison.md), rules 1, 2, 4 and 6).
The preview ends with a digest of what it said; `take --yes <digest>` acts on that preview and nothing
else, and a preview that has changed since, or an account of the machine older than the flip allows, is
refused as the flip's is. A module the machine holds nothing for has nothing to compare, and `--yes`
suffices. The overrides are `--downgrade`, `--replace <path>` and `--mint <name>`; the per-machine
setting that keeps a found network is `networks`, a container id to the networks it keeps, accepted
for an adopted machine only. Storing a setting composes it against the module's current definition and
refuses, naming node, module, layer and key, what cannot compose or reaches nothing. A definition that
later moves under a stored setting costs that module its place in the machine's declaration, said by
name in `plan`, `push` and the declaration itself, and the machine is told everything else; a stray
setting no longer refuses the machine where it is read. *How it is checked:* controller tests over the
one judgement — refused where stored, a module left out where composed, the envelope naming it — and
over a take's digest, staleness and secrets.

mesh-host 64: genesis raises the forge under the module's container name (`gitea`), pinned to the
module's image digest, with the module's data directory mounted at `/data` — so the module finds it,
holds it, and a take compares equal images and the same data. A test holds the installer's constants
to the module's manifest where the catalogue is checked out beside it. The network is the difference
left: the bootstrap forge runs on the machine's network to reach the store on its loopback, the module
runs bridged and publishes its ports, and the take says so. Closing waits for group 9's genesis test —
a mesh raised, the module assigned, and the module found holding rather than raising a second forge.
