Issue 110's cause was not the filter: the runtime had never been told,
and the resolver dropped a query arriving on a bridge. ADR 0148 step 3
landed once it did (109, 151 resolved). ADR 0151 composes a route's
internal name under the serving node and drops the suffixed alias
(139, 157 resolved). Design 08 amended; a fact in 0148 corrected.
Answers issue 151. Copying the roster into each container made the roster
part of each container's identity, so one name moving replaced every
container in the mesh — and it never stopped the staleness it was for,
since a copy taken at creation is stale the moment the roster moves (109,
135).
A container resolves through its machine's resolver instead, and nothing
is copied. Staleness stops being possible rather than detected, and a
name's blast radius becomes nothing.
Scoping each container to the names it binds was the close call and is
rejected: it contradicts anything-calls-anything, and leaves the roster
in the digest so the churn returns for a widely-bound name.
Gated on issue 110 — a container on the runtime's default network has no
DNS at all today. Removing the copy first reintroduces 109 and 135
silently on a live mesh. 151 stays open until the code lands; design 08's
file-not-resolver passage is narrowed to the machine's own roster.
Found reviewing the resolver's conversion. Nothing fails while the node is adopted; it
fails at the flip, and it is the same split that decided which container survived the
hub's address change.
