Live node-state stream (SSE, S14): rolled-up display-state changes as they happen. The inventory and topology views seed from REST once, then patch individual nodes off this stream instead of re-fetching the whole fleet every 15s. Works in skeleton mode — the alert engine is always present.

The ADR-019 envelope every failure renders as. pub(crate) and schema-bearing so the OpenAPI document can name one error shape for every endpoint (ADR-035) instead of leaving 4xx/5xx bodies undescribed — a client that has to guess the failure shape ends up parsing the success shape and reading undefined.
