Two consequences of the one predicate, on review. The filter's "from the mesh" set is that same
set now, so a rule admits exactly the machines the mesh names. And a machine whose assigned set
fails to resolve is no longer on the network in the mesh's eyes: its name leaves every other
machine's hosts file and every resolver's zones on the next push, and the mesh's report of that
machine's failure is what says why — the stated preference for a name that fails at once over a
connection that hangs, at the cost of one machine's failure being visible mesh-wide.

*On review.* `INFO` is in the dangerous category and several client libraries ask it at connect;
it reads nothing a consumer keeps, so it is allowed back. Whether the catalogue's two cache
consumers need anything else the category removes is unverified — and moot until they present the
login they were granted ([issue 081](../081-a-cache-consumer-does-not-use-the-login-it-was-granted/00-report.md)).

# 081 — A cache consumer does not use the login it was granted
## Symptom
Two catalogue modules require the cache and are given a login and a password under a keyspace of
their own ([issue 080](../080-a-cache-grant-lets-the-consumer-flush-the-server/00-report.md)),
and neither tells its software the login: each hands it the host, the port and the password only,
so the software authenticates as the server's default user and writes wherever it likes — or is
refused, if the default user is closed. The grant is honoured by the provider and ignored by the
consumer.
Found on review of issue 080, by reading the two manifests. Not run: no bed installs either
module against the catalogue's cache and reads what it wrote.
## Why it matters beyond the instance
A grant is two ends agreeing. The provider's end is checked by the grant bed; the consumer's end,
that the software actually presents what it was given, is checked by nothing but the module
working — and a module that works as the default user works.
## What would close it
Each module passes the login it was bound (`${bound:redis-cache:as}`) to its software's username
setting, and a bed installs one of them against the catalogue's cache and reads back that its keys
sit under its login.
