ADR-0004: Boot Defaults to Desktop

Status: accepted

Context

The control-plane specification asks whether the system should replay the last desired mode after reboot or normalize to a safe default. Replaying compute after reboot could surprise the operator and re-enter a throughput posture without current evidence.

Decision

In v1, boot normalizes to desktop.

Do not replay the last desired mode across reboot.

Consequences

• First boot behavior is predictable and operator-friendly.
• /run/mode-controller can remain ephemeral for live state.
• Persistent desired replay can be revisited after transition behavior and audit history are proven.
