Drill: 8 states: one table component, all 8 states (loading skeleton, empty, error, partial, filtered-empty, sorted, selected, overflow). Each state must be correct.
Interpretation: Built as Fenris, a satellite ground-station contact schedule for a 12-sat smallsat constellation (station GC-3 Reykjavik) — an identical 8-column contract across all 8 state panels, with shape-divorced status vocabulary (filled dot / ring / pulsing dot / rotated square across only 2 hues) and dropout rows that preserve failure context (lost-time + % of pass completed). Light dev-tool operator aesthetic: Inter + JetBrains Mono, 13px body, hairline dividers, one indigo accent; mobile prunes columns via triple-hide and re-surfaces them as a mono subline under each satellite name.
Satellite passes assigned to station GC-3. Times UTC, derived from TLE epoch 2026-09-04 22:31.
First paint after station handover. Skeleton mirrors the live column contract — no layout shift when rows land.

Empty station · 0 of 22 passes assigned
GC-3 has no assigned contacts yetNot an error — the constellation is passing, but Fenris Ops hasn't assigned traffic to this station yet. The planner re-runs every 4 hours from the latest TLE set and prefers GC-3 for high-el S-band windows. | |||||||
Cause first, reassurance second, recovery third. The table stays honest — nothing is rendered from cache.
Partial data is data — the banner explains what's hidden, the rows prove what survived.
