KQL Dashboard editor

A KQL Dashboard is a multi-tile dashboard backed by KQL queries. Each tile pins one query + a viz type (table, line, bar) and is re-runnable via the dashboard's Re-run-all button.

Backend

Layer	Implementation
Persistence	Cosmos DB items container, state.tiles: [{title, kql, viz, database?}]
Execution	ADX /v1/rest/query per tile, fan-out at GET ?run=1 time
BFF routes	GET /api/items/kql-dashboard/[id] (read, with optional ?run=1 to inline results), PUT /api/items/kql-dashboard/[id] (save tiles)

What works today

Action	Backend call	Status
Read tiles	Cosmos read	live
Run tile (server-side fan-out)	ADX /v1/rest/query	live
Add / delete / inline-edit tile	client state + PUT on save	live
Save tiles	Cosmos replace()	live
Edit JSON (raw tile array)	client state	live
Re-run all	GET ?run=1	live

What's intentionally honest-disabled

Parameters	Dashboard parameter editor not yet wired
Auto-refresh	Per-tile auto-refresh schedule not yet wired
Time range	Global time-range picker not yet wired
Share	Dashboard-share / permissions not yet wired

Bicep

Same backing as KQL Database — dashboards are pure client-side composition over the same ADX cluster.

Env vars

Same as KQL Database.
