 produced the defect: two places composing one name. The control plane now hands the suffix it
 composed the names with down to the facts, so an operator who chose another gets that one and
 nothing appended. What remains unproven by a bed is a mesh with a suffix other than the default.

+
+# 080 — A cache grant lets the consumer flush the server
+
+## Symptom
+
+The cache provider's provisioner creates each consumer an ACL user confined to keys under its own
+login and allowed every command. A key pattern confines only commands that name keys. `FLUSHALL`,
+`FLUSHDB`, `CONFIG`, `SHUTDOWN` and the rest of the dangerous category name none, so a consumer
+granted "its own keys" could wipe every other consumer's, or stop the server.
+
+Found by carrying the large mesh bed's retired tenancy assertions into the grant end-to-end bed:
+`FLUSHALL` as the consumer answered `OK`.
+
+## Why it matters beyond the instance
+
+A grant is the mesh's promise that a consumer gets what it asked for and nothing else. The
+promise was checked on the key pattern and never on the command set, and the one bed that had
+asked was retired before it was run against the catalogue's module.
+
+## What would close it
+
+The ACL user is allowed the ordinary command set minus the dangerous category, and the grant bed
+asserts a write outside the consumer's keys and a `FLUSHALL` are both refused.

+1. The provisioner's `ACL SETUSER` gave `~<login>:*` and `+@all`. Redis applies a key pattern to
+   commands that take keys; a command taking none is governed by the command categories alone,
+   and `@all` includes `@dangerous`.
+2. Fixed with `-@dangerous` after `+@all`. `KEYS` goes with the category; `SCAN` stays, and is
+   what a consumer scoped to a prefix should use.
+
+**Located in:** the redis module's client. Not a decision. Proven by the grant end-to-end bed.
