Module dashboard 

Building a DashboardModel from a live embedded session: the executed plan as a DAG with placement tags, per-operator counters aggregated from the session’s TelemetryHub, and per-column profiles of the registered tables. This is what oxide tui --query … renders; without a query the CLI falls back to the synthetic demo fixture.

Functions

plan_summary

The physical plan as the dashboard’s DAG rows (pre-order, with depths).

profile_table

Profiles every column of table: min, max, null count, and P25/P50/P99 (numeric columns only) — one aggregation query per table.

query_dashboard

Runs sql on session to completion and returns the dashboard model for it: the executed plan with placement tags, the aggregated telemetry the run produced, and column profiles for tables.
