a commander's bound is a rule, not a list

the allow list shipped an hour ago was a snapshot. plugin permissions
register at mount, so a plugin installed after a commander was created was
missing from its list and failed as a bare 403 with nothing saying why —
and every future thing a commander is meant to do is exactly that shape:
notify a device, send mail, spawn a sub-agent, hand a transcription to an
idle one, reach a plugin that does not exist yet.

so a credential now narrows two ways, and both only subtract:

  permissions   an ALLOW list. exact, a snapshot. right for a credential
                with one job.
  excludedKinds kinds it may never reach, resolved against the LIVE
                registry on every request. right for a credential whose
                job is open-ended.

a commander gets the second: every kind except admin. bounded away from
installing plugins, managing users and roles and changing server settings,
forever — and open to everything the platform learns to do, with nothing
to re-issue. still intersected with the account, so for a member it
narrows itself against their role.

verified against the running server with a commander-shaped key: tasks,
notify, file-browser and the transcribe PLUGIN all reach their routes;
/api/users, /api/plugins and /api/roles are 403. the plugin case is the
one an allow list could not have passed — it was mounted long after any
key was minted.

the commander's CLAUDE.md says what it cannot do in the rule's own terms,
and that a 403 is an answer rather than a problem to route around.
