Change intelligence

What changed on the map

The worker writes map facts into cache: a one-time baseline of each researched layer, then add/remove rows when membership moves. Each fact has a permanent URL. Not a ranking and not a trade signal.

Status right now

Cache read: ok.
Membership moves in this window: 0. Zero means no add/remove yet — not a refresh failure.
Researched-layer baselines in this window: 16.

Focus layer: Compute. Rotates across layers with complete sources — not by price.

Membership moves

No ticker add/remove rows in this window yet. Researched-layer baselines below are the first seed; membership moves appear when a later refresh changes a layer.

Researched layers (baseline)

Snapshot of companies on each researched layer when the change log was first seeded. These are real cache facts with permanent URLs — not an empty page.
