Aleksei Sviridkin ae5b626c8f docs(gateway): describe the passthrough listeners and what they shed
The chart README gains the native-port field, the three limitations it
carries and where each comes from, the one that is a phase-1 narrowing
rather than a consequence of the Cilium pin, and the three ways forward
for anything that depended on a terminate listener the change takes
away. The withdrawal is stated as what it is, a change of serving path
rather than the removal of something idle, because on the pinned
version both filter chains carry the SNI today and nothing on the
objects says which one answers.

The layers section is brought back in step with the listeners: which
label each listener class selects on, that the attach set is the whole
inheriting tenant subtree rather than the tenant plus the admin list,
and the route conditions an operator reads, including the one that says
the sectionName itself names nothing.

The platform values comment on gateway.enabled said every exposed
service renders an HTTPRoute, which the chart value the withdrawal
reads contradicts. It now separates them: the services whose TLS the
Gateway terminates get an HTTPRoute, while api, vm-exportproxy and
cdi-uploadproxy get a TLSRoute pinned to their passthrough listener,
one each from the packages that own those services.

The overlap paragraph no longer describes an HTTPRoute wildcard as
keeping its terminate listener. Such a claim is refused under HTTP-01,
which issues no wildcard certificate, and the paragraph says so and
what the render used to do with it. The route-condition list gains
that shape and the port shapes an HTTPRoute now reaches, and the
per-app naming bullets carry the hash suffix the rendered names have.

Two sentences that were false against the code are corrected: a
TLSRoute on a wildcard entry itself leaves the names beneath it their
terminate listeners, and an unusable apex is refused by the containment
rule at admission before the controller's own check is reached. The
edge section says what happens to the entries the HTTP-01 pass wrote
once the mode moves.

The NoMatchingParent sentence now separates the two kinds: an
HTTPRoute pinned to an absent passthrough section is refused whatever
answers its hostname, while a TLSRoute is judged where a passthrough
listener answers it.

A sectionName outside the passthrough prefix is written Accepted like
any attached route rather than left without a verdict, and the text
says so; the port-80 listener's refusal joins the NotAllowedByListeners
shapes and the name-and-port disagreement the NoMatchingParent ones.

The attachedNamespaces comment described the list as reaching every
listener, which the native-port ones do not: they select on
kubernetes.io/metadata.name and name the publishing tenant alone, so a
namespace listed there cannot attach to a database port. It also
credited the wrong label with keeping the list honest; what a listed
entry gets is the namespace.cozystack.io/gateway label, and what keeps
a tenant from stamping it on itself is that no tenant role carries
patch on Namespace.

The class reference is brought along. Its certificate-mode table
promised one Certificate per published hostname under http01, which a
hostname served by a passthrough listener no longer earns, and its
edge table said every attached TLSRoute is refused, where only a route
declaring hostnames is and the rest have this controller's entry
removed instead.

The refusal-shape list is corrected against the code, without a count
of its own so the next correction does not have to move one. A route
the plain-HTTP listener turns away on its namespace
selector was listed under NoMatchingListenerHostname as well as under
NotAllowedByListeners; the controller reports the second. The port
shape standing beside it swept port 80 back in by naming every port
but 443, where a route selecting the plain-HTTP listener is answered
by the namespace shapes and never reaches the port refusal at all. And a
TLSRoute pinned to an absent section is said to carry
NoMatchingListenerHostname where no passthrough listener answers its
hostname, which holds only while no HTTPRoute claims that hostname:
with one there a terminate listener stands on the name, and the route
is judged like any other attached route.

The wildcard shape gains the same qualifier. A wildcard claim is
refused because no terminate listener can carry a certificate HTTP-01
will not issue, so the refusal reaches a route that wanted a terminate
listener and not one that asked for the plain-HTTP listener, which
carries no hostname and serves the claim there.

The Helm merge paragraph named the two-way path as what happens to a
custom resource Helm has no Go type for. That path is one of two in
createPatch, the version deciding which runs, and the version comes
from helm-controller rather than from this tree, so the claim was not
checkable where it was written. It now names both and says the outcome
it rests on holds either way.
