+
+Steps 4 and 6 could not be checked through chat, because no utterance reaches
+Praxis (**475**). «что требует внимания» routes to `intent=query` and is answered
+by the search leg, identically whether `ecosystem-praxis-1` is up or stopped. The
+degraded string never appears because its branch is never entered. Step 5 is
+blocked the same way: `перезапусти muzick indexer` clarifies on

+
+**250** passes steps 1, 2, 3, 9 and 10 on the deploy. The capability announces
+itself. `/models` names the model llama-server reports, not the config filename.
+Asking her to switch models does nothing. Removing `swap_models` renders `swap
+not configured`. Step 4's refusal half passes at HTTP 403, and the 403 comes from
+mavend rather than mavweb. WebAuthn is unconfigured, so the web gate fails open
+and the wire gate fails closed. Steps 5 to 8 need a passkey assertion nothing on
+this box can produce. They pass in test: 13 swap cases and 7 page cases covering
+drain, mid-swap refusal, rollback, failed rollback and the not-owned refusal.
+
+**249** passes steps 1 and 2. Step 3 stops it. `mavupdate` health-checks over
+`/run/maven/mavend.sock`, which is `srw------- 1 10001 999` inside a docker
+volume. The host owner cannot traverse `/var/lib/docker/volumes` and cannot
+connect to a socket owned by an in-container uid. `mavupdate` assumes a
+host-installed daemon and the deploy is containers. Do not sudo around this.
