The manifest already uses serves for a provision's facts, so a module's
tools take their own key. Declaring them is itself new — until now a
module's tools existed only in a runtime environment variable.
Storage is not a property of a subject — a stream is a separate object that
covers one — so the question is always how many streams, not which topics
are durable.
Three facts decide it, two of them verified rather than assumed: NATS
refuses overlapping streams instead of merging them, so a shared stream
plus a per-module one is not available at all; a filter cannot express an
exception; and a stream per module turns one cross-module consumer into one
per module. So one stream, with per-subject caps for the fairness that
matters. Per-module age is genuinely unavailable, and a module that needs
it declares a seat.
2.3 was already true and is now proved — the seat refusal is generic, and
three tests pin what matters: a second bus is refused by name, a different
bus implementation is refused too (which is what makes the bus replaceable),
and the AMQP broker no longer contends so both run on one mesh.
2.1/2.2 turned out not to be a no-op. The host keeps a container only when
its spec matches exactly; genesis raises the upstream image and the module
declares the mesh-built one carrying the entrypoint, so assigning it
recreates the container. That is ADR 0067's pivot and it is safe only
because the bus carries nothing yet — which is why step 2 comes before
anything speaks NATS. After it, never again: the config is a directory
mount, so accounts change without touching the container's spec.
Design 29 said no module requires the bus. The catalogue disagrees: 49 of
72 modules take a broker credential and 23 do not, so an ambient connection
mints an account for a third of the catalogue that never speaks — and the
49 each hand-write the path it lands at, which is provisioning done badly
by hand.
The bootstrap argument that made it ambient was narrower than it looked.
"A provisioner needs an account before it can run" is true of a provisioner
process and says nothing about a provision the controller answers, and the
controller is not waiting on a bus account to compose one.
So: the mesh-broker seat delivers mesh-bus; a module requires it and gets an
address, a sealed credential and the trust to verify the server; a module
that requires nothing has no account at all. The requirement delivers the
connection, the declarations shape the authority, and declaring a subject
without requiring the bus is refused as incoherent.
mesh-bus and nats are deliberately two names: a module may run its own NATS
as a backing service exactly as one provides amqp, and a manifest saying
"nats" would otherwise mean either the mesh's nervous system or a private
queue.
The seat's Delivers was wrong twice today — amqp, then empty — and the
comment says so rather than reading as though it were always right.
0117 went a step further than it had grounds for. It was right that the bus
is the only bus, and wrong that the amqp interface must therefore retire —
because it conflated two reasons to want a broker. Using one to reach
another module is a second bus and stays refused. Needing an AMQP broker as
a backing service, the way something needs a database, is ordinary, and
forbidding it would make the mesh unable to run normal software while
calling that architecture.
So the broker becomes a plain provider module: no seat, not foundation,
never raised at genesis, no retirement condition. lavinmq now claims nothing
and provides amqp; nats claims mesh-broker and provides nothing.
The rule that survives is about direction, not software: inter-module
communication goes over the bus. A module may hold a broker for itself; it
may not use one as a channel to another module. That is a review judgement
where 0117 could have used a parser, which is the honest cost.
0106's progressive insight was itself wrong and is corrected by a second one
there — nothing moves off the old broker, so its "one purpose" sentence does
not become true, it is just not what that server is.
The insight check needed two fixes it found itself: a date may carry
trailing words, and a bold run with a link is discussing an insight rather
than marking one. All four bad shapes still fire.
1.1 to 1.4 built and tested. 1.5 turned out to need no controller change:
it already resolves the broker by seat and names no broker module in its
source, which is what ADR 0079 was for. The genesis module set naming is
scenario and installer config, carried with the bed.
Recorded what must NOT change yet: the amqps:// credential shape and the
5671 default are correct until the rollout, because steps 1-4 leave every
node on AMQP.
29 put a module's events and tools in one namespace, 25 kept mesh.events.*
and mesh.tools.*. One namespace is right — a module's authority over its own
name becomes a single pattern the server enforces — but it needs a kind
token, because a stream is a subject filter and mesh.mod.*.> would persist
every tool call in the mesh. Tools stay on core NATS for the reason 25
already gives.
So: mesh.mod.<module>.event.<name>, .tool.<name>, and seats the same shape.
Found composing the first real configuration. Scoping every inbox to its
owner is right and leaves a responder unable to reply, because the answer
goes to the caller's inbox. The fix is not a wider grant but the server's
own allow_responses: one reply to the subject of a message the user actually
received. Without it every tool call times out while the permission list
looks correct.
Versioning: additive is free; a breaking change is refused while callers are
bound, and the refusal names them, because the mesh already holds the uses
graph; a real break versions the subject, not the seat name, so the role
does not fork; binding is a recorded pin, not a drift to whatever is newest.
Semantic change stays open — no fingerprint sees it, and saying so beats
implying the check is complete.
Provisioning: a provisioner's create/remove/holds IS a serves protocol, so a
provision interface is a seat that also delivers a credential — which is why
design 26 already allowed that. The per-consumer resource is what stops the
two collapsing into one.
Secrets: sealed, so the bus is never trusted with plaintext — but sealed is
not enough, because a stream persists and a durable ciphertext is an archive
the day a key leaks. So a secret never enters a stream: core request/reply
only, and a declaration names a secret rather than carrying one, which is
0098's fetch-don't-store applied where carrying is worst. The vault's own
credential and the bus's own accounts are the two bootstrap exceptions,
resolved the way 0067 resolves the control plane.
Also rewrote the addresses paragraph, which was too compressed to follow:
on-bus addresses disappear because nothing stores them, off-bus ones are
untouched and still 0098's problem, and the bus's own address is the one
that cannot be a subject.
The architecture 0117 opened needs a module to offer a service as a role on
the bus — one holder, addressed by what it does. A closed table in the
controller cannot express that: a capability a module contributes would
require changing the mesh itself.
But 0110 closed the set for a good reason — nothing could say what seats a
mesh had, and the hand count came out at eleven of thirteen. That argues for
enumerable, not hardcoded, and 0110 weighed free-form against a fixed table
without considering a third option: closed at any moment and derived from
the catalogue. A derived list cannot drift, which is how the count broke.
So: the mesh's seats stay the mesh's, reserved by the mesh- prefix so the
prefix is the rule and there is no list to maintain; ten seats are renamed
to restore 0079's convention; everything 0110 decided about what a seat IS
survives untouched.
Design 29 carries the declaration model: three namespaces, subjects derived
from local names so a manifest survives the wire changing, queues never
declared, five relationships (the job and state shapes 0041 had no room
for), and the build-publish-deploy lifecycle with hard, soft and build-time
dependencies distinguished.
0041 gets a progressive insight: "no per-consumer setup, only a
subscription" was a fact about a topic exchange, and a JetStream durable
consumer is a real object someone creates.
WBS 1.3/1.4 were wrong and say so: streams come at registration and
consumers at assignment, so only the foundation set belongs at genesis.
Issue 115 is resolved and converted four modules away from named volumes;
the bus's own data is not the place to bring one back. Also: NATS carries
TLS on the client port rather than beside a plaintext one, so there is no
5671/5672 pair to mirror.
A module does declare requirements the provisioner fulfils — but the broker
it gets that way is a private vhost, the analog of a database, not the
mesh's bus. Two modules of the new mesh depend on it, so the compatibility
broker was never single-purpose and its retirement would have stranded them.
NATS is the heart: one bus, a module's messaging is subjects on it scoped by
what it declares, and no module is handed a server of its own. The seat
delivers nothing; the interface retires with the broker. Also closes the
EVENTS question — one stream, on the bootstrap argument, not preference.
Designs 25 and 28 go in-progress: step 1 is starting.
The insight check caught a false positive on its own first real use — its
bold-run pattern crossed newlines and joined an unrelated `**` to the
marker. Constrained to one line, still catching all four bad shapes.
Both repository checks fail on main. 0115 is cited by no design, and it is
marked accepted while resting on 0112, which is proposed.
Design 27 already states the rule the record decides — "a module is assigned
at most once to a node, and that pair is the assignment's identity" — so it
is the home, and now says so. And 0112, 0113, 0114 and design 27 are all
proposed: the batch is under review, so the record is too. Promoting 0112
instead would be marking a record accepted to satisfy a check, which
check_rests_on names as a failure this repository already made once.
PR #133 landed a different 0115 while this branch was open. The bus record
is now 0116, with every citation in designs 19, 25, 28 and the index
following it.
Note: cycle.py and records.py both fail on main as merged, on that record —
nothing cites it, and it rests on 0112, which is still proposed. Both
pre-date this branch and are left for their own change.
A record can assert a fact that goes stale while the decision it supports
stays right. Superseding for that buries a sound record under a second one
and makes every reader work out which is live. So a correction of fact is
now made in place, marked and dated, with the old wording quoted — bounded
by three conditions and checked by records.py, which fires on an unmarked,
undated or back-dated note. Judgements still supersede.
Applied to 0115: no conformance suite exists to recapture, and the full
genesis bed cannot run until the links exist. Designs 25 and 28 follow.
Counting the surface first changed the plan twice: the genesis bed cannot run
until the links exist, so it belongs to step 4, and there is no conformance
suite to recapture — step 3 builds one against the current bus before moving
it. Both corrections are recorded in the breakdown rather than edited into
ADR 0115. Also indexes design 25, which was never listed.
The NATS change was recorded as one undivided item, which hid three gaps:
a mesh already running had no adoption path, the protocol specification did
not know its transport was being replaced, and nothing was runnable until
everything was. Dividing it is what surfaced them.
Both halves are on their main branches, so the seats stop being an intention. Writes the as-is
document from the controller's code and the catalogue's manifests: the closed set of fourteen, the
three refusals a claim meets, the holder being an assignment and nothing else, and the one place a
seat changes resolution — which of several providers answers, never whether a requirement may go
unanswered.
Two things the as-is layer exists for are stated rather than smoothed over: a seat cannot answer
before it is held, which is the standing condition issue 121 records; and capacity is not
implemented at all, so the design's bench has no counterpart in the code.
The seats half of to-be 27's review is settled, so the two records it rests on are accepted and
the vocabulary catches up: the glossary's *seat* becomes a named role from a closed set, held by
an assignment and possibly delivering a provision, and 23 — Choosing a provider gains the seat
step in resolution, with ambiguity still refused rather than guessed. Both were held back when
0110 was proposed, because a document may not rest on a record that is not accepted.
26 — The seats moves to in-progress rather than designed: it names the files that implement it,
and naming a file claims implementation, which is only defensible once those files are on the
owning repositories' main branches. It becomes implemented when mesh-controller #63 and
mesh-catalog #69 land.
0112, 0113 and 0114 stay proposed; to-be 27 stays proposed with them.
The fact-check found mailu, whose user is its mailbox, so 0114 rotates
over two credentials rather than two logins, the adapter choosing what a
credential is. Also: minio keeps non-empty buckets; five backends take
their admin credential only at first init, so single-party rotation is
staged; postgres ownership moves to a non-login role; the harness keys by
consumer; rotation state lives with the vault. Consistency fixes across
0110-0113, 26 and 27; issue 103 resolved by mesh-host PR #22.
Graduates research 016. Retiring a login is separated from removing a
consumer, which closes a data-loss path in five providers; single-party
secrets rotate in place; the number of parties decides, not the provider.
Overlap as drafted in 0113 would have deleted consumer data: seven of
eight providers name the resource after the login and five drop it on
remove. Rotation is now undecided in 0113 and to-be 27, pending the
survey. Also: a requirement naming a seat resolves to its holder, a
person chooses among remaining candidates at assignment, the controller's
secrets are requirements of its definition, genesis seals to the
control-node key, and moving the vault or broker is break-glass.
Decided with the author. A credential is never changed in place: each consumer has two logins, both
derived by the mesh, and uses one at a time. An applier adds the new login beside the old through the
adapter's existing create, and confirms both work; only then are readers released to the new one and
restarted by derivation; only when every reader has confirmed is the old login retired through the
existing remove.
It closes the three cases review found in applier-first rotation: an offline reader keeps working on
the old login until it returns; a bus account's owner keeps its bus until it has moved; a provisioner
restarted mid-rotation is still delivered both values. Nobody is ever without a credential that works,
which replaces to-be 13's all-or-nothing rule with a stronger one.
No consumer module changes. The alternation is the provider loop's. A provider's adapter gains one duty,
giving both logins the same rights over the consumer's data — in postgres, membership of one role that
owns it. The mesh derives two logins per consumer, both within ADR 0049's limit, which 0113 now names
among what it amends. Every rule has a check: overlap, offline reader, bus account, restarted
provisioner, equal rights, login length, and confirmation only once the old login is gone.
Decided with the author:
- A seat is held by one assignment, not claimed by a definition. A definition says which seats a module
can hold; an assignment says which it does. The store module can run on every node and one assignment
holds mesh-store; moving a role changes an assignment, never a definition. The foundation's seats name
what the mesh itself uses and route no consumer — database and amqp consumers use co-location, the
holder included. This replaces the wrong rationale that the foundation's store is "provider to nobody",
which contradicted ADR 0078 and to-be 21. 0079's one-postgres rule becomes one mesh-store holder.
- A module is assigned at most once to a node. The instance identity in 0112 and 27 is withdrawn, and the
login-length problem with it.
Review fixes to 0113:
- The bottom of the stack: the vault is installed as soon as the shared runtime base exists, and genesis
generates everything needed until then — including the permanent controller's, the control-node
agent's, the builder's and the broker provisioner's bus accounts, and the controller's store login.
Genesis creates those accounts until the broker's provisioner runs and adopts them.
- Genesis's values are delivered recorded as the mesh's own, so 0092's never-replace rule for operator
values does not make them unrotatable.
- Backend-issued secrets (a forge's once-only API token) enter through the vault. Non-module parties
(the controller's logins, node agents' accounts) are answered the same way, the controller asking on
their behalf; an enrolment token reaches the controller only as what verifies it.
- A secret with no provisioner to apply it is marked not rotatable by the mesh and refused, instead of
a restart reported as done. Unused password generators in six provider clients are removed, and a
catalogue scan checks no module mints.
- Rotation's lock-out cases (offline reader, bus account owner, restarted provisioner) are recorded as
open, with overlap and re-confirm-with-safeguards as the two answers, to be chosen before acceptance.
0110, 0111 and 26 are marked proposed: they changed in meaning and are under review, and an accepted
record must not rest on proposed ones. To-be 23 and the glossary are restored to main; they change when
these records are accepted.
Two decisions taken with the author:
- Genesis delivers and the vault adopts. The vault cannot run first — it is built on the runtime base
the installation makes after the store, broker and controller, and it learns its work over the bus.
Genesis generates the foundation's first shared secrets, seals them to the operator key, and
delivers them to the vault through the path an operator's value takes; from then on the vault holds
and rotates them. This answers ADR 0085's own reason for rejecting vault-only minting, which 0113
now names instead of stepping around.
- Rotation re-confirms on every pass. An applier repeats its confirmation until acknowledged, so a lost
message costs one pass; an applier that stops after applying locks readers out until its supervised
restart, and that window is stated and shown, not claimed away.
Fixes:
- Scope: a shared secret is made by the vault; a private key (node sealing keys, the operator's key,
the certificate authority) is made where it is used. The inventory adds the makers the first version
missed: node and builder broker passwords, and enrolment tokens.
- Broker accounts are created by the broker's provisioner, not the controller, so the controller never
holds their plaintext; mesh-broker delivers amqp again — one broker per mesh — and only mesh-store
delivers nothing.
- secret is a reserved provision: only the mesh-vault holder may provide it, and no pin routes around it.
- A secret's contract says whether a recipient applies it or reads it at start; appliers are never
restarted for it, init-only secrets are applied, and confirmation is to-be 13's standard.
- Operator secrets are one rule everywhere: a secret requirement answered by the vault (0112 no longer
says otherwise). A data provider's adapter may return fields; the data-return check names a lab consumer.
- 'Holder' now means a seat's holder only; a secret has recipients.
A secret comes into being seven ways today: provider credentials, own secrets (54 modules), broker
accounts through a command that is easy to forget, a vault that only records what the controller
mints (6 modules), operator values, licences, and root secrets. The vault was built to end own secrets
and did not; the old path was never retired.
0113 is rewritten as a waterfall. The vault makes every secret and nothing else does. A provider that
needs a secret for a consumer requires it from the vault, declared once in its provision's contract
and expanded per consumer by resolution; the vault delivers it to both holders, each sealed to its own
node, so a provider's code is unchanged. Own secrets, broker passwords, operator values and licence
credentials take the same path. Genesis is not an exception: it raises the vault first and asks it,
so there is one way a secret is made from the first one on. The vault can sit at the bottom because it
requires nothing but a broker account.
One shared mint function in the SDK was considered and rejected: generation becomes uniform but custody
stays spread over every provider's machine, and each SDK language needs its own implementation.
Rotation is asked of the vault and is provider-first: the value goes to the holder that accepts it,
which confirms, before the holder that presents it gets it, so the lockout window shrinks to the
consumer's own restart, and an unconfirmed provider holds the rotation rather than half-doing it. The
host derives which processes to restart or recreate from the requirement a definition reads, so no
definition declares restart-on for a secret. A rotation shows unconfirmed until each consumer restarted
and passed its health check. Issue 103 becomes a prerequisite.
The file is renamed to match what it now decides. 0112 follows.
0113 — the plaintext claim was false under its own mechanism: handing a provider's answer to the
controller puts every secret on the broker and in the controller in the clear. The provider now seals
each secret field itself, to the consumer node's public key the mesh hands it, and the controller
carries sealed fields it cannot open. That is stricter than today, where the controller holds every
minted credential in the clear. Option 3 (plaintext to the controller) is recorded and rejected. The
foundation exception now covers root-secret rotation (0085) and forms like the broker admin's hash, so
no phase claims to remove the broker's bootstrap step. To-be 24 and 13 are named among what it amends.
27 — resolution is consistent with 0110: co-location and the only provider apply only where no seat
delivers the provision, so an unheld seat is refused even with one provider. The secret-field rule now
matches 0086 exactly (a declared env-file, never a container environment value). The seat placeholder
is the controller's, and the one module reading it moves to a host port. Contracts are held by the
controller and written down in phase 1, so they can be checked; every rule has a check. An operator's
secret is still the operator's, with the vault as custodian. Which seats a module holds is listed as
not settled.
0110 — the unheld-seat-with-one-provider case and the one-answer-for-everyone rule have checks; the
claim about moved manifests is corrected. 26 — the table governs and the code catches up, not the
reverse; scope and capacity agree with the glossary; moving a seat is described as it really is today.
0112 — aligned with 27, and lists 0049 and 26 among what it changes.
Issue 118 is renumbered 119: another branch took 118 first. 'Control-plane' is gone from 0110 and 0111.
The design pass. Everything a module needs is a requirement: a name, a contract, and one of four kinds
of provider — a module, the node's host, the mesh, the operator. Installing a module resolves every
requirement or refuses, naming everything missing at once. It retires six mechanisms that grew
separately: provisions through bindings, settings, assigned ports, machine facts, minted secrets and
literals in the definition.
ADR 0113, proposed: a provider makes what it provides, and the mesh carries it back sealed to the
consumer's node. It is the return path ADR 0048 left "to a separate decision", now needed three ways:
data provisions with nothing to answer with, contracts needing a value the controller cannot make, and
a vault that generates nothing. Who a consumer is stays the mesh's (ADR 0049). Genesis is the one
exception. On acceptance it supersedes 0048 and amends 0085.
ADR 0112 is revised from three sources to that single concept.
ADR 0110 is amended for two points raised in review. The vault gets the mesh-vault seat (issue 106).
A seat's holder outranks co-location for a provision it delivers. Writing that down exposed an
inconsistency: mesh-store delivering postgres-database would have sent every database consumer to the
control-node, against to-be 23's node-local stores. So a seat delivers a provision only where the mesh
has one answer for everyone — artifact store, npm registry, git, vault — and mesh-store and mesh-broker
deliver nothing. 23 and 26 follow.
'Control plane' becomes 'controller' in the records written today.
The enumeration behind the first set read manifests in two repositories and missed a claim made
in the control plane's own code: the private-network module it ships claims the-private-network at
node scope. A closed set without it would refuse the control plane's own module. Thirteen claims in
use, naming twelve seats.
Seats have been doing two jobs and neither is written down. The mechanism ADR 0009 introduced is
enforced — a second holder is refused — but any well-formed name becomes a seat by being claimed,
and nothing can say which seats a mesh has or who holds them: holdings are assembled while planning
and discarded. The enumeration done while preparing this missed the control plane's own manifest,
because core modules' manifests live in its repository rather than the catalogue.
0110 closes the set. Each seat has a name, a scope, what occupying it delivers, and the record that
made it one; a claim outside the set is refused. A seat is held by a module assignment, and what the
mesh knows about the holder is what it knows about that assignment — nothing is stored beside it. A
seat may deliver a provision, and then its holder answers for it among several providers: pin, then
the holder, then the only provider, then refused. That keeps 0009's "refused, never guessed": the
seat is the choice made once, mesh-wide, instead of a pin per consumer node. The first set is the
eleven seats already claimed plus 0109's npm-package-registry, so nothing in use is refused.
Two concepts — seats for exclusion, a new word for consumable singulars — was rejected: both mean
"this mesh's one X", and the overview a person wants is one list.
0111 gives the mesh a git seat and makes a build source one of two explicit forms: a repository on
the seat's holder, recorded by its path and cloned from wherever the holder runs at build time; or
an external URL, recorded and cloned exactly as given. Recognising self-hosted sources by matching
URLs against the forge's address was rejected — it fails in the one case it exists for, after the
forge moves. Credentials for private repositories are left undecided and said so.
Design: new to-be 26 (the seats); 23 gains the seat step in resolution; 18's source entry names
the two forms; the glossary's seat and provision entries say where they meet. 0109 is carried from
its own branch so every link here resolves.
Extends ADR 0075. Surfaced fixing builder's hand-faked package-registry
binding tonight: gitea's manifest declares the provision once with a single
npm-path, conflating what should be independently assignable per ecosystem
(npm/cargo/docker/...) the same way artifact-store and package-registry
were themselves split. Cited in 22-the-work-ahead.md's Phase 2, where the
target state this decision points at was already described a week ago.
Numbered 109, not 108: route-proxy's policy feature (mesh-controller PR
still-unwritten decision record — reserved but never committed. Renumbered
around it rather than colliding.
Issue 116 found the mesh's proxy applies nothing to a request — host lookup, forward. Against
what the replaced ingress actually relies on, four capabilities are missing: authentication
(three dependents, each gating an admin surface with no login of its own), refusal scoped to a
path (one, a live incident mitigation), path-scoped routing with priority, and redirect.
Policy goes on the route rather than beside it. A proxy-side settings layer keyed by route name
would keep the grant literally clean, but then "what protects this route" is answered from two
files nothing keeps in step — and a route's protection is part of what a route is.
The set is closed at those four, so a fifth is an amendment and each addition is earned by a
dependent that exists. An open middleware surface was rejected: it recreates what is being
replaced, and narrowing one later is far harder than widening a closed one.
Where policy needs a credential the declaration names a secret and never carries the value,
which keeps the existing secret machinery the only thing holding credentials. Inlining a hash
was rejected as the first credential in a declaration — a precedent easier to set than withdraw.
This re-keys the routing table by host and path with priority, which follows from the decision
rather than being a separate one: two of the four need one host routed more than one way. Equal
priorities must resolve identically every time or the proxy stops being reproducible.
The record says how it is checked, including the negative case that rots quietly — a
declaration carrying a credential value rather than a reference must be refused, so the
rejected option cannot return by accident.
08-connectivity §3 names the record and gains the subsection; issue 116 gains amended-design.
Fixes, each named where it was wrong:
- reload-on is a service field; a container only has restart-on, which
recreates. Cited precedent (registry-trust-reload) is a service resource,
not a container. Fix: nats-server's own SIGHUP reload, triggered by an
in-image entrypoint watching a directory-mounted config file (issue 103's
recreate-on-change applies to a directly-mounted file, not a directory's
contents) -- asks nothing new of the host.
- A JetStream-delivered message's Reply field is already claimed by the
consumer's own ack address, so a responder using it answers nobody. Fix:
every CONTROL message needing a reply carries its reply subject in its own
payload; the controller publishes there explicitly, never via Respond().
Enrolment is the case this design actually depends on, so it's fixed there
too, not just noted.
- The listed permissions never granted publish on a durable consumer's own
ack-reply subject -- a module could receive but never ack, so every
message redelivers forever. Fixed with a scoped grant per module's own
consumer.
- One account (a deliberate choice, kept) means inbox privacy is the
permission list or nothing. The design granted 'its reply inbox' without
scoping it, which read as any user reaching any inbox. Fixed: each user's
inbox prefix is derived from its own identity and its permissions name
only that prefix.
New open question from this revision, not closed: whether the in-image
watch-and-SIGHUP shape belongs in mesh-sdk if a second module ever needs it.
Checks pass (records.py, cycle.py, index.py).
Both from the review of the issue-104 fix: a hand-applied file on an enrolled node is
recorded as carried and would remove the foundation, and nothing on the wire orders one
declaration against another.
Two birth-address outages and a registry that would have been the third; a
container that keeps a stale environment after its file changes; a host command
that applied a converged declaration to an adopted node; the hub and the vault
without seats. And the decision the operator made under it all: the hub adopts
the predecessor's tunnel in place, key and peers and range and port.
