The reader's subscribe allow-list spelled `$SWARM.term.*`,
`$SWARM.term.*.sub.*` and `$SWARM.agent-state.*` as literals, copies of
private prefixes in hive-agent and swarm-controller. A rename on either side
left the policy behind and the stream stopped with only a connection-level
server error.
swarm-queue-client now owns `term_subject`, `agent_state_subject` and their
`*_wildcard` forms, and `subagent_term::subject_wildcard`; hive-agent's
publishers, swarm-controller's relays and the policy all build from them.
Subjects are byte-identical.
The handlers read the agent's status only to learn whether it has ever reported; no hive is used to build the stream. The 404 and 500 messages and their OpenAPI descriptions now say that.
The terminal and turn-state relays now subscribe to `$SWARM.term.<agent>`
and `$SWARM.agent-state.<agent>`, the subjects a verified agent token is
granted, as well as the hive-scoped `<prefix>.<hive>.<agent>` an agent
still on its hive's shared credential publishes to. Both at once, so a
swarm-ui terminal keeps working whichever credential an agent connected
with and in whatever order hosts deploy.
mara's review point on #4351: an agent isn't pinned to a hive forever
(it can move), so a URL naming one would go stale the moment it did.
Resolve the hive at request time from the agent-status bucket instead
-- the same source AgentStatusRow.hive already comes from -- rather
than trusting a caller-supplied value. Route is now
GET /api/agents/{name}/term/stream; a never-reported agent now answers
404 (no hive on record) instead of silently guessing.
hive-agent already publishes classified TermMsg rows to the core NATS
subject $SWARM.term.{hive}.{agent} -- live only, no retention, by
design. This endpoint subscribes that subject per request and relays
each row over SSE, opaque to this daemon (no TermMsg dependency, same
pass-through shape crate::status already uses for hive snapshots).
No replay/history: the publish side never grew JetStream retention, and
this route's own job (a live tail) never needed it.
