The plan says what an apply would change from the declaration and the
record, before the machine is touched. The apply now recreates a container
when the content of a file it reads at creation changed, and the plan said
"check" for every recorded container — true, but a preview that hides the
one step somebody asked about.
So a recorded container whose record of what it read differs from what this
apply will hand it — a plain file declared here, by its declared content;
otherwise what this host last wrote at that path — is planned as an update
naming the file, the same comparison applyContainer makes. What the record
cannot settle stays a check: a file neither declared nor recorded is read
from the machine by the apply, not by the plan; and a container with no
record of what it read was labelled before the host kept that record and is
accepted as it is.
novox/hq 04-ISSUES/103, 104
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.
