"""Consolidated registration inputs (PRD 0070, docker slice).

Bridges the existing per-bottle `prepare` output to the consolidated
registry: turns a prepared bottle's egress plan into the backend-neutral
inputs `Orchestrator.launch_bottle` takes — the egress **policy** blob and
launch **metadata**.

The policy blob is the exact routes YAML the per-bottle egress sidecar used
to read from a file; in the consolidated model the multi-tenant gateway's
`PolicyResolver` fetches it from the registry per request (keyed by source
IP) instead. Same render, so consolidated and single-tenant egress apply
byte-identical policy — a bottle's allow-list doesn't change when it moves
onto the shared gateway.

Host-side glue (imports `bot_bottle.egress`), used by the launch path — not
by the lean orchestrator control-plane process itself.
