Review of the fix for hq issue 104 found three faults in it. A file applied
on an enrolled node — the mesh's own last declaration included — is applied
as the bundle is, so its resources are recorded as the machine's own and
what the mesh declared reads as undeclared: the plan removed the foundation.
`apply FILE` is for a machine the mesh has not spoken to, and is now refused
saying so whenever declared.json exists. The plan looked at what is held
before what the declaration says is taken, so the one cutover ADR 0100 says
must be previewed read as a hold; it now decides in holdOnAdopted's order,
models a step run inside a held container, and a test holds the plan's
sequence to the apply's outcomes. Genesis wrote the mode on every run, so a
re-run after `converge` left the state saying adopted while the kept,
signed declaration said converged, and the reconcile loop refused every five
minutes with no delivery coming to end it: genesis now writes the mode only
when none is recorded, and where the state and the verified kept declaration
disagree, the kept declaration wins and the repair is said.
Also: a file lock beside the state, taken by the link service, the host's
own commands and the installer alike, so a `reconcile` run by hand no
longer races the loop's save — chosen over refusing while a named service is
active, which would miss a `mesh-host run` started by hand; `--json
--dry-run` emits {plan} like an apply emits {plan, report}; the README's
duplicate flag line; and the bundle refusal is about the digest, not a claim
the carried bytes can never match what genesis applied.
An operator ran `mesh-host reconcile` on an adopted control-node with twelve
modules assigned. It applied the bundle the host carries — the genesis
declaration, foundation only, converged: recreated the store, failed on the
broker's held port, wrote the converged base filter and started its service,
and stopped at the first failing action. The filter closed the machine for
forty-five minutes. The host reported the node adopted in every report, the
declaration said converged, and nothing compared the two; nothing was printed
before acting (hq issue 104).
The host now records the node's mode — from every declaration the mesh sends,
and at genesis from what the operator said — and refuses, at the point of
application, a declaration that says the other mode, naming both and the act
that changes it. Only a declaration the link delivers, signed, changes the
mode: that is how `converge` and `adopt` arrive, so the flip still works and
nothing else can do it. Genesis marks the bundle consumed, with the digest of
what it applied, so `reconcile` holds a node the mesh has spoken to against
what the mesh last said and never the bundle, and refuses the carried bytes
when they are not what genesis applied. A file is refused when it is not what
the mesh last said: a declaration carries no sequence and no issued-at, so the
host cannot tell older from newer, and says so. Both commands print what they
would change — a hold, a removal, an action named as one — before touching
anything, and --dry-run is that list and nothing more.
Registering a module is an overwrite. Recording the forge's port ran `module add`
every time, so a genesis re-run pointed at an older catalogue would replace the
manifest of a forge that is built and assigned — with a push a few lines later.
Registering is only here so a settings row has a module row to hang on, and that
row is already there on a mesh that knows the forge. So: ask first, and skip.
Two comments narrowed to what is true. What follows the node's setting is what
the mesh derives from a module's ports — its container mapping, its filter rule,
its opening and what it serves. The forge's own address in its runtime's
environment (hq 088) and its route contribution's port do not, and are already
wrong for any port the mesh assigned. And a settings layer is the module's, not
one resource's: a second mergeable file on the builder would be given `serves`
too.

Every foundation port given at genesis became a per-node setting of the module
that binds it, except the package registry's: that one was fixed by rewriting
the builder's manifest when the installer registered it. Registering the builder
again from the catalogue undid it, and the forge's own module, when it took the
bootstrap forge over, came up on the catalogue's port — which on a machine where
a predecessor holds 3000 points the builder at the predecessor's forge.
So the rewrite is gone, and the port is recorded twice as a setting, both from
the one input:
- the forge's module is registered at genesis — not assigned, nothing of it runs
— so the controller has something to hold `{"ports": {"3000": <given>}}`
against. Assigning the forge later raises it on the port this machine was
given, and its container, its filter rule, its opening, what it serves and
what consumers are told all read it from there.
- the builder is given `{"serves": {"port": <given>}}`, which merges into the
binding it carries in place of one nothing can resolve yet.
A genesis on the catalogue's port records nothing and registers nothing, so it
does exactly what it did before.
