0071. The machine list shows the Ready condition, not Talos's stage

Status: Accepted · Date: 2026-10-26 · Design section: UI Decided: The machine list drops its "Stage" column. Machine.stage is only filled by the node view (GetNode), which dials the machine; the list reads CRs only. The approved list shows the TalosMachine Ready condition (status and reason) instead; the pending list shows no status column.

Context

The machine list's Stage column always showed "-". Root cause: machineToPB sets Stage: "" on purpose (ADR 0018 keeps Talos's own MachineStatus stage a GetNode concern), the controller records no stage in TalosMachine.status, and the list never calls GetNode. So the column could never have a value. A pending machine in maintenance mode has no credentials to dial, and a stage per row would mean one Talos call per row on every list load.

Decision

Keep Machine.stage in the proto for the node view, remove the always-empty column, and show what the controller does record: the Ready condition. The Talos stage belongs on the machine page's Talos details, where one node is dialled.

Consequences

• No new controller status field and no per-row Talos call on the list.
• A control plane that is approved but not Ready shows False / its reason (for example RebootRequired) in the list.
