Mirror each remote session's self.log into a bounded buffer, drained by the client via GET /api/session/{id}/logs and re-emitted locally. Server-account sessions get no relay. Also namespace service CLI options under service_params so a transport key (profile) no longer collides with a service's own option, on both the session and download-job paths.
Renames 314 defs and 41 module/class-level constants. Keeps 11 names underscored where the stripped form collides in scope, plus 5.5.0 shims for the three symbols external service repos call.
Derive both setup_routes and setup_swagger from one ROUTES table, and move the repeated trailing APIError->response block into an @api_handler decorator.
Covers RemoteClient/RemoteService, REST routes, handlers, SessionStore, InputBridge, DownloadQueueManager, errors, compression, and serve CLI. E2e tier opts in via --live and can auto-spawn its own serve.
