Across the package: - claude_bottle/platform/ -> claude_bottle/backend/ - platform/docker/platform.py -> backend/docker/backend.py - class BottlePlatform -> BottleBackend - class DockerBottlePlatform -> DockerBottleBackend - get_bottle_platform() -> get_bottle_backend() - env var CLAUDE_BOTTLE_PLATFORM -> CLAUDE_BOTTLE_BACKEND - dict _PLATFORMS -> _BACKENDS "Backend" is shorter and more established as the term for a pluggable strategy-pattern implementation. "Platform" was vague (could mean OS, hardware, cloud) and mildly redundant — Docker is itself a platform. The previous PRD section claiming "the Backend protocol was rejected" referred to a low-level run/exec/cp/network_connect protocol; the name was never the reason. The PRD is updated to describe that rejected design by shape rather than by name. The bottle/agent concepts and the manifest schema are unchanged.
