-  matrixEnableRemoved = ''
-    The per-agent matrix switch is gone. Matrix is enabled for an agent exactly
-    when it has at least one services.hyperhive.agent.matrixAccounts entry, and
-    the hive-internal `main` entry is declared for you whenever
-    services.hyperhive.agent.matrix.url is non-null.
-
-    - `enable = true` was the default: drop the line, nothing else to do.
-    - `enable = false`: set services.hyperhive.agent.matrix.url = null instead
-      (and declare no accounts of your own). That is what leaves the account set
-      empty, which is now what suppresses the daemon, its path watcher and the
-      injected extraMcpServers.matrix entry.
-
-    See docs/tools/matrix.md.

   hiveNameRemoved = ''
     An agent reads its hive's name at runtime from /etc/hyperhive-hive-facts,
     which the hive writes into every container, so no agent build sets it.
