-The `/supervise/propose` + `/supervise/poll` pair is the **agent** half of the
-supervise flow: the data plane (supervise / egress / git-gate) queues a proposal
-and polls for its response over RPC instead of opening `bot-bottle.db` directly.
-`poll` is idempotent — it never archives, so a dropped connection can't lose an
-operator decision (the row is reaped when the bottle is torn down / reconciled).
-Both attribute the caller by `(source_ip, identity_token)` exactly like
-`/resolve`, so a bottle can only ever queue or read its own proposals.
-
-`POST /bottles` / `DELETE` drive the full launch lifecycle: they mint (or
-tear down) the bottle in the registry AND broker the backend-native launch
-via the orchestrator. Register/deregister without a launch are internal to
-`OrchestratorCore`, not exposed here.
-
-Routing/handling is the pure function `dispatch()` so it is unit-testable
-without a socket; `Handler` / `OrchestratorServer` / `make_server` are a
-thin stdlib adapter around it. Listing redacts identity tokens — they are
-returned only once, to the caller that launches the bottle.
