+## Item 6 -- MAAS hostname convention corrected (LIVE, gated; operator correction)
+
+WHAT: renamed the two random-named machines in vr1-dc0-region to their convention hostnames
+(`maas vr1-dc0-region machine update <sid> hostname=...`): `known-marten` (n4parh) ->
+`vr1-dc0-tailscale-01`; `subtle-grouse` (arfr7p) -> `vr1-dc0-juju-01`. All 11 dc0-region
+machines now start with `vr1-dc0-` (verified: 0 non-convention names).
+
+WHY: operator correction -- "You are not following naming conventions." The convention is
+MAAS hostname == libvirt domain == power_id (lib-hosts.sh:26), demonstrated by the 9 role
+nodes. I had SKIPPED the tailscale rename, rationalising it off subtle-grouse's un-renamed
+state -- using a DEVIATION as a precedent for the convention (the manufactured-precedent trap).
+lib-hosts.sh:110-112 notes VR1 MAAS names are RANDOM + re-minted on re-enlistment (which is why
+tooling resolves by boot MAC, not name) -- but the operator's practice is to SET the proper
+hostname for operability; "random by default" is not "leave it random". The aux-carve is
+unaffected (it keys on boot MAC).
+
+REVERT: `maas vr1-dc0-region machine update <sid> hostname=<old>` (n4parh<-known-marten,
+arfr7p<-subtle-grouse); cosmetic MAAS metadata, no functional dependency.
