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.
Three issues named the branch that fixed them, and a branch is deleted
when it merges — so every `fixed-by:` was a pointer that resolved to
nothing by the time anyone followed it. They name commits and pull
requests now, and playbook 03 says to.
Two records were missing the thing a reader arrives for. 146 did not say
that one of its fixes crash-looped the control plane on a running mesh,
which is the whole reason the delivery subject carries the stream and the
raise path was the only one exercised. 151 did not say that 152 removed
the false reasons its roster moved, or that it stays open for the real
ones.
ADR 0080 enumerates what cycle.py enforces and named four things; it
enforces five. A progressive insight names the fifth — the decision
stands, the list had gone stale. The checks README and playbook 03 gained
the same rule, and 155 points at all three.
ace numbered its two records 147 and 148, which this repository already
uses; they become 150 and 151, as 127 became 149.
The new record is why the control node could not stop applying: the
roster alternates between two values because routeNamesInTheMesh
swallows a per-node plan failure, and the roster is part of every
container's identity. The loop closes through the control plane's own
store, which each pass replaces.
