What the coverage probe is, the URL contract, branching (covered / partial heal / cold ingest / login prompt), Server Action → ingest route → polling, and pointers to pipeline and read-path docs.
How chart reads call the `get_fire_data` RPC, catalog caching, and TypeScript types.
Shipped surfaces under `app/(main)/` — navigation labels, read paths, and feature doc pointers.
`/atlas` chapter rail, URL filters, and read-only charts over materialised `fire_data` rows. Pair with read-path doc for RPC semantics.
Analyse route status — presentation-only page; correlation/cross-tab code removed. Future work reads get_fire_data.
Recharts vs ECharts, Progress, and totals helpers. Split from the former data_model inventory.
`/dashboard` is a drag-and-drop, snap-to-grid block canvas where users compose stat + chart blocks over the shared `FireDataQuery`. Layouts persist per user; blocks read from one snapshot (plus per-override re-reads).
