Worker cards showed a hand-maintained workerLabel that went stale on every topology switch. The snapshot now carries workerDerivedLabel, a display-only mirror of the head's live served model: only when role is worker, workerHeadId resolves to another spark, and the head probe entry is available with a non-empty modelId. Unavailable entries are skipped so a dead/protected head never yields a stale model. A non-empty manual workerLabel still takes display priority; nothing writes back to config. Adds 8 regression tests (override priority, head-offline, standalone, self/unresolvable head, stale-entry skip).

Verified locally against current main: clean diff, 180/180 tests pass including 8 new fail-closed worker-label tests, TypeScript check passes, production build passes. Reviewed resolver wiring and UI precedence; manual labels remain authoritative and stale/unavailable head models are excluded.
