Issue 171: a module that names its own resolver knows no mesh name

Found and fixed the afternoon ADR 0148 landed: mailu-admin lost its
database behind Mailu's own resolver. Two catalogue PRs; an insight on
0148 that a container's dns is a decision, not a preference.

+# 151. A route's internal name is composed under the node that serves it
+
+## Context
+
+A module that requires a route is given two names from one label: a public one, `<label>.<public
+domain>`, and an internal one, `<label>.<node>.internal`
+([ADR 0138](0138-an-assignment-binds-an-endpoint-and-says-how-far-it-reaches.md)). Both were composed
+from the node the module runs on.
+
+The two are answered differently. The public name is published into every machine's roster at the
+address of the node whose proxy serves it ([ADR 0066](0066-public-routing-is-name-agnostic.md)), so
+it reaches the proxy from anywhere in the mesh. The internal name is answered by every machine's
+resolver as *anything under a node's name goes to that node*
+([design 08 §2](../03-DESIGN/01-to-be/08-connectivity.md)) — the node it was composed from, which is
+the consumer's. Where the proxy runs on another machine, that name sends a client to a machine with
+nothing listening, while the public name works
+([issue 139](../04-ISSUES/139-an-internal-route-name-resolves-to-the-consumers-node/00-report.md)).
+Every route on this mesh today is served beside its module, so it has not been seen; `route` is
+provided mesh-wide precisely so that stops being true.
+
+Beside it, the roster gave every routed name a second entry with the mesh's suffix appended —
+`<name>.<public domain>.internal` — because it composed a full name for every entry as it does for a
+machine. That name resolved on every machine, was served by nothing, and was refused by the proxy at
+the handshake; the first three names tried while reproducing an unrelated issue were those, and the
+evidence pointed at a regression that had not happened
+([issue 157](../04-ISSUES/157-a-routed-names-internal-alias-is-served-by-nothing/00-report.md)).
+
+## Considered Options
+
+**1. Keep the consumer's name and publish it at the serving node's address**, as the public name is.
+The name stays `<label>.<consumer>.internal` and an exact roster entry overrides the wildcard.
+Rejected: it makes `<x>.<node>.internal` mean *goes to that node* except when it does not, which is
+the one rule the resolver design states; it needs an entry per route where the wildcard needed none;
+and which of an exact entry and a wildcard a resolver answers first is the resolver's business, which
+the mesh deliberately does not know.
+
+**2. A proxy on every machine, so the serving node is always the consumer's.** Rejected for this
+question: it is a different decision about what `route` is — a node-scoped seat with a mesh-wide
+fallback — and this mesh runs one proxy on the hub today. Whatever is decided there, a route served
+from another machine must have a name that reaches it.
+
+**3. Compose the internal name under the node that serves the route.** Chosen.
+
+## Decision
+
+**A route's internal name is `<label>.<serving node>.internal` — composed under the node whose proxy
+answers the route, which is the machine the request arrives at.** The public name is unchanged:
+`<label>.<public domain>` of the node the module runs on, which is where the operator put it.
+
+Where the proxy runs beside the module — every route on this mesh today — the two nodes are one and
+nothing changes. Where it does not, the name says where the request goes, which is what a name under
+a node's name has always meant.
+
+**A routed name has no mesh form.** The roster publishes it as itself, once, at the serving node's
+address. Only a machine has a bare name beside its full one.
+
+What certifies the internal name is unchanged by this: the proxy that terminates it obtains a
+certificate from the mesh's authority for the names it is given, and it is given this one.
+
+Taken on the operator's standing instruction to answer the open design questions in the work order.
+
+## How this is checked
+
+- **Composition.** A controller test contributes a route from a module on one node to a proxy offered
+  from another, gathered the way the controller gathers a consumer's contribution for a provider on
+  another machine, and asserts the internal name carries the serving node.
+- **Publication.** A controller test renders a roster with a machine and a routed name and asserts
+  the routed name appears as itself, once, and never with the suffix appended.
+- **On the mesh.** After the change no machine's roster carries a `<domain>.internal` entry, and a
+  route's internal name still answers from a container with a certificate from the mesh's authority.
+
+## Consequences
+
+- **A route served from another machine now has a usable internal name.** The first module assigned
+  that way will resolve, where before it would have resolved to the wrong machine with no error.
+- **The internal name of a route can change when its proxy moves.** A route re-homed from one proxy
+  to another gets a new internal name, as the design's rule implies; clients that dialled the old one
+  reach the old machine. The public name does not move with the proxy and is the stable one.
+- **The roster is one line shorter per routed name**, and a person reading a hosts file no longer
+  finds names that resolve to a refusal.
+- **Issue 139's second question — a per-node route holder — is left open**, and is a decision about
+  what a seat is rather than about a name.

+*2026-09-30. Measured on the mesh.*
+
+## What was done
+
+**Hosts first, then the controller** — the order [issue 087](../087-the-controller-cannot-tell-a-host-is-too-old/00-report.md)
+says a new declaration field needs, and now a build and a push rather than an expedition
+([issue 142](../142-the-host-is-the-one-thing-the-mesh-does-not-deliver/01-progress.md)).
+
+The host understands a `sequence` on a declaration and tolerates its absence: absent reads as "no
+order claimed", not "first", so a controller that sends none is still understood and a host that kept
+a declaration before it understood the field compares nothing. It refuses a declaration with a lower
+sequence than the one it kept, whole, and says why; and the drain that picks one declaration from a
+batch keeps the highest sequence rather than the last to arrive — which is the case the report
+constructed, a backlog drained out of order.
+
+The controller numbers each send: the next number for that node, taken under the node's hold, before
+the body exists, so the number is inside what the mesh signs and a replayed older declaration cannot
+borrow a newer one's.
+
+## Measured
+
+```
+push shanks; push shanks
+sequence in kept declaration: 2
+node      sequence
+novox     2
+shanks    2
+ace       (none — not sent since numbering)
+g14       (none)
+status:   nobody "not running what the mesh would send them"
+```
+
+Both applies went through; neither was refused; the machine holding the earlier one accepted the later.
+
+## The subtlety, which would have read every machine as behind for ever
+
+The mesh decides a machine is behind by comparing the digest of what it **would** send against what it
+**did** send. A number changes the bytes. So the read-only comparison composes with the number the
+machine was *last* sent — not a fresh one — and is byte for byte what was sent when nothing else
+changed. Without that, numbering would have made `status` name all four machines as out of date on
+every reading, permanently.
+
+## The open questions
+
+- *A per-node `sequence` under the controller's node hold?* Yes, as described. **`supersedes` — the
+  previous digest — is not added.** A strictly-greater sequence gives the ordering; a chain of digests
+  would give continuity, which nothing here needs yet and which every re-composition would break.
+- *Genesis signing its bundle as sequence zero?* Zero is "no order claimed", which is what the bundle
+  carries by carrying nothing. Same rule, no genesis branch.
+- *A marker for a mode change?* Not needed for the incident it guards: a replayed converged declaration
+  reaching a node returned to adopted is already refused **by mode**, before this check runs.
+
+## How it is checked
+
+Host: an older sequence is refused, a newer or equal one is not, and no order claimed on either side
+compares nothing; the drain keeps the highest sequence, and falls back to arrival when none is claimed.
+Controller: a send carries its number inside the signed bytes, an unnumbered send is byte for byte what
+it was before, and each node's counter is one higher per send and readable for the comparison.

+
+*2026-09-30. Measured on the three converged machines; the adopted one holds its resolver module until it
+is taken and is not covered.*
+
+## What was actually wrong
+
+Not what the report predicted. The report named the filter: a container on the runtime's default
+network asks from a bridge address, and the converged filter admitted queries by source address only.
+That was true when it was written and was fixed before this issue was ever tested — the filter admits
+by the link a packet arrives on ([ADR 0144](../../02-DECISIONS/0144-anything-on-a-machine-may-call-anything-on-it.md)),
+and a container's bridge is admitted whole. Tested on every machine: the query arrives, the filter
+passes it.
+
+Three other things were wrong, each hiding the next.
+
+**The runtime had never been told.** The resolver module writes the runtime's `dns` key into the
+runtime's own configuration file. The runtime reads that key when it starts and not on a reload, and on
+two machines the runtime predated the file — so every container they started got a public resolver, and
+`novox.internal` came back as not existing. Nothing reported this: the file was present and current,
+the resolver ran, and a name not existing is a valid answer. Fixed in mesh-catalog PR 175: the module
+also sets `live-restore` and reloads the runtime when its file changes, so the one restart the `dns` key
+needs no longer stops every container. The restart is then the operator's, once per machine; done on
+both today, with every running container kept.
+
+**The resolver dropped the query.** With the runtime corrected, a container's query reached the resolver
+— and got no answer, on every machine, including the one whose runtime had been right all along. The
+socket was bound to the private address; the filter admitted the packet; dnsmasq received it and
+discarded it without a line of log. Its configuration said `interface=mesh0`, and dnsmasq admits a
+query by the interface it arrives on when told an interface: a container's query is addressed to the
+private address but arrives on the runtime's bridge, and the bridge is not `mesh0`. Fixed in mesh-catalog
+PR 176: the resolver is told the address to answer on, not the interface that carries it, and a query to
+that address is admitted whatever bridge brings it. The bridges are the runtime's to name.
+
+**The report's second half was wrong.** "Two of four machines bind the resolver to loopback only" was
+an inference from the containers' behaviour, and the behaviour had the cause above. The resolver bound
+the private address on all four; nothing had asked it there.
+
+## What is verified
+
+From a container on the runtime's default network, started by hand and given nothing, on each of the
+three converged machines: `novox.internal` answers with the hub's private address, through the machine's
+own resolver. That is the fourth check of
+[ADR 0148](../../02-DECISIONS/0148-the-meshs-names-are-resolved-not-copied-into-containers.md) — "on every
+network the runtime offers" — and its first step; the record's step 2 (the runtime told per machine, as
+a file) was already how the module works. Step 3 may now begin.
+
+## What checks it
+
+By hand, today. Nothing in the mesh asserts that a container can resolve a mesh name: the resolver's
+own tests cover what it answers, not who can ask. The check that would have caught all three faults is
+the one the report asked for and 0148 lists — a container on the default network resolving a mesh name
+— and it is not built. It belongs with the reachability check of
+[issue 145](../145-a-machine-reads-healthy-while-its-modules-cannot-reach-each-other/00-report.md),
+which is parked; until then this is a thing a person verifies after touching the resolver, the filter,
+or the runtime's configuration.
+
+## What this cost to find
+
+The three faults produced one symptom — a container that cannot resolve — and each fix revealed the
+next. The first was found by reading the runtime's own view of its configuration rather than the file;
+the second by capturing the query on the bridge and finding it arrive and go unanswered; the third only
+by admitting the first belief was wrong. A machine that had been believed to work all day had never
+worked either.

+
+[ADR 0151](../../02-DECISIONS/0151-a-routes-internal-name-is-composed-under-the-node-that-serves-it.md):
+the internal name is composed under the node that serves the route — the machine the request arrives
+at — because `<x>.<node>.internal` means *goes to that node* and nothing else. The public name stays
+the consumer node's, which is where the operator put it. The first question is answered that way; the
+second, a per-node route holder, is a decision about seats and is left where it is; the third is
+unchanged, since the proxy that terminates the name is given it and certifies it.
+
+mesh-controller PR 163 carries it. On this mesh every route is served beside its module, so no name
+changed; the controller's tests hold the case where it would.

 One thing this found on the way out: an archive cannot be undeclared, and the attempt stops the machine

+The last delivery was unattended on all four: the fixed host was built, pushed, each machine stood
+aside exactly once for the genuinely newer version, and the delivered launcher started it — no
+restart by hand. A following push that delivered nothing new was applied and reported by every
+machine and stood nobody aside, which is the check
+[issue 163](../163-a-delivered-host-stood-aside-on-every-push-and-reported-nothing/00-report.md) asks
+for.
+
+**Two more faults on the way, both mine, both found by reading the machine rather than the success
+line.** A delivered host compared the newest delivered version against its link-time stamp rather
+than the version it was running, so it stood aside on every push and — because standing aside cancels
+the report — never reported again (163). And the adopted machine kept its found launcher as the
+adoption rule says, so the delivery there needed a `take` before the launcher moved.
+
+**The crossover needs one restart of the unit per machine, once.** The launcher process that was
+running on each machine was the old script, executing from its own inode; a new file beside it
+changes nothing until the unit restarts. Every subsequent delivery is unattended.
+
+**Timing, measured:** on a machine, hearing a declaration to reporting it applied is about three
+seconds. A push as the operator sees it takes 17–20 seconds, and the difference is the control plane
+composing the declaration before it sends. A `--wait` shorter than that reads as "did not report" for
+a machine that did; the three-minute default read as slowness for a machine that never would. Neither
+number is a defect being chased here, and both are worth knowing before reading a push's answer.
+
+## What this leaves
+
+- [Issue 162](../162-an-archive-cannot-be-undeclared/00-report.md): an archive cannot be undeclared, so
+  the host module — and any module with an archive — cannot be unassigned, and trying stops the machine
+  applying anything.
+- [Issue 107](../107-a-declaration-carries-no-order/00-report.md) is unblocked: a declaration field is
+  now a build and a push rather than an expedition.
+- Three stale version directories on the workstation from the first attempts, moved aside under
+  `/var/lib/mesh-host/versions-held-back/`, and a backup of the adopted machine's hand-placed binary
+  beside its state. Both are safe to delete and are not the mesh's to delete.

+
+## What was observed
+
+*2026-09-30, rolling the mesh-built host onto the last two machines.*
+
+Every push to a machine running a delivered host produced, in order:
+
+```
+host 093231796eb0 is delivered; standing aside so the launcher runs it
+applied 333 resource(s)
+applied, and could not tell the mesh: reporting: context canceled
+nox-mesh-host-launch: the host exited cleanly; starting it again
+nox-mesh-host-launch: running /usr/lib/nox-mesh-host/versions/093231796eb0/nox-mesh-host
+```
+
+— for the version it was **already running**. It restarted itself on every push, for ever, and the mesh
+never received a single report from it: `node show` kept the version from before the crossover, and
+the operator's push waited its full three minutes for an answer that was never coming.
+
+Read as healthy throughout: unit active, bus link up, "hearing what this node should be".
+
+## Why
+
+After an apply the host asks whether a newer host has been delivered than the one running, and the
+question was asked with the **link-time version stamp**. Since
+[issue 161](../161-a-delivered-host-carries-none-of-its-link-time-facts/01-resolution.md) a delivered
+host's version comes from where it sits and its stamp is `development build` — so the comparison never
+matched the newest delivered version, and "a newer host is waiting" was always true.
+
+Standing aside cancels the context the report is published with, so the report was lost on every one
+of those applies. Two faults from one wrong argument.
+
+The change that moved the version to the path was applied to the report and to the known-good record,
+and not here. Half a change, and the half left behind was the one that decides whether to exit.
+
+## Why the three-minute wait made it invisible
+
+The push's `--wait` timing out read as *slow*. It was not slow: **the report was never going to arrive.**
+The operator put it exactly: *if you don't get a response in five seconds, something is wrong.* A wait
+long enough to absorb a machine's whole apply is a wait long enough to hide that the machine never
+answered.
+
+## How it is checked
+
+A machine running a delivered host is pushed a declaration that delivers nothing new; it applies,
+reports, and does not stand aside. A machine running a delivered host is pushed a genuinely newer
+version; it stands aside once, and the next push it does not.

-plex's X-Plex-Token, nzbget's ControlPassword, qBittorrent's WebUI password. Their consumers' pair
-credential must be **accepted** by the operator (ADR 0092). Until it is, `SecretFor` mints a random
-value, seals it to both ends, and reports nothing: the value can never work.
-
-Every consumer therefore had to learn to detect it — try the credential against the provider first,
-refuse a value the provider rejects, print the `secret accept` command — six write-in steps, one probe

-
-## What would be right
-
-A provision (or a provider's `serves`) can declare its pair credential **accepted-only**. The plan then
-refuses the pair — naming the accept command — instead of minting, and a consumer is never handed a
-value the mesh knows cannot work.

+## What was observed
+
+The afternoon [ADR 0148](../../02-DECISIONS/0148-the-meshs-names-are-resolved-not-copied-into-containers.md)
+landed — no container is given the mesh's names any more; it asks the machine's resolver — the mail
+system's admin container began logging, 523 times in three minutes:
+
+```
+psycopg2.OperationalError: could not translate host name "novox.internal" to address: Name does not resolve
+```
+
+Mail was accepted on every port and the web front answered; the admin and the spam filter beside it
+were unhealthy, and anything that needed the database — a mailbox change through the API, the spam
+filter's domain list — failed. Found by the operator asking whether mail was back, forty minutes in.
+
+Mailu ships its own resolver, an unbound in a container, and every other Mailu container is told to
+use it — the module carries `dns: [192.168.203.254]` on eight containers. That resolver recurses from the
+root and knows nothing under `.internal`. Until that afternoon the admin container had the database's
+name anyway, because the mesh wrote every name into every container at creation; the copy was the only
+reason a container behind its own resolver could reach anything by a mesh name, and nobody knew it was
+load-bearing.
+
+**Removing the override was not enough.** Given the machine's resolver instead, the admin refused to
+start: `Your DNS resolver at 127.0.0.11 isn't doing DNSSEC validation`. Mailu checks, at start, that
+its resolver returns the Authenticated Data bit for a signed name. The mesh's resolver forwards to two
+upstreams that validate and set the bit, and dropped it on the way down — dnsmasq does unless told
+otherwise. Mailu's own unbound has no hook to forward a zone elsewhere, so it could not be taught the
+mesh's names either.
+
+## Why it matters beyond this instance
+
+**A container with a resolver of its own has opted out of the machine's, and nothing says so.** 0148
+made the machine's resolver load-bearing for every container; a `dns` on a container is a quiet
+exception to that, and the exception used to be papered over by the copy the record removed. The
+manifest field reads like a preference and is a decision about whether mesh names exist inside the
+container.
+
+**A resolver that forwards to validating upstreams and hides the fact is less useful than it could
+be**, and the first program to check found out.
+
+**The mesh reported nothing.** Every container ran; the failing one accepted connections; the report
+was about bytes. It is [issue 145](../145-a-machine-reads-healthy-while-its-modules-cannot-reach-each-other/00-report.md)
+again, and the check that would have caught it is the same unbuilt one.
+
+## What was done
+
+- The one Mailu container that binds a mesh name — the admin, through the database it is granted —
+  no longer names Mailu's resolver and uses the machine's, like every container without a `dns` of
+  its own (mesh-catalog PR 178). The other seven keep unbound: the spam filter needs a validating
+  resolver for its blocklist lookups, and none of them asks for a mesh name.
+- The machine's resolver passes the DNSSEC bit down from its upstreams, `proxy-dnssec` (PR 179). It
+  does not validate itself; the trust is the upstream's and the path to it, as a forwarding resolver's
+  always was, and the configuration says so.
+
+## What checks it
+
+The admin container's own start-up check, which is what failed, and the mesh's status once it reads
+healthy. A container-level check that a mesh name resolves from inside every declared container is
+the one 110 and 145 both ask for and is not built.
+
+## Open questions
+
+- Should a container's `dns` be refused, or made to say what it gives up? A module that names its
+  own resolver and binds a mesh name is a contradiction the controller can see at composition — the
+  grant hands it a name its resolver will not answer.
+- Should the machine's resolver validate rather than proxy? It would cost a trust anchor on every
+  machine and make the resolver slower to start; proxying was enough for the one program that asked.
