D113 — One client status snapshot across CLI and dashboard

Status: implemented (2026-07-28).

Decision. Client status is collected once into a versioned, renderer-independent snapshot. Table commands, JSON output and the Bubble Tea dashboard consume that snapshot. A failed endpoint request produces one classified server error and marks connected provider state unknown; JSON keeps the wrapped cause while human output gives the endpoint and an actionable next step. Command discovery is grouped and conservative, and the dashboard adapts its presentation and visible actions to terminal width and selection.

Rationale. Independent render paths had drifted into separate network calls and contradictory repeated errors. A small stable schema gives scripts a safe contract while keeping the terminal interface concise, and makes the dashboard an alternate view of the same facts rather than a second status implementation.
