v1.4.0

v1.4.0 - 2026-05-26

Metrics dashboard

• Gmail-style row checkboxes with select-all (indeterminate state)
• YAML import / export for metric definitions
• Bulk delete with confirmation
• Inline row editing (display_name, kind, dataset, description)
• Excel-style multi-select column filter headers (matching Checks page)
• Removed verdict dot badges from table rows

Checks page

• Edit button replaced with pencil icon for visual consistency

Remove calculated-metric authoring (breaking)

The expression-builder path (SQL expression authoring, evaluate endpoints, MetricRun
table) has been removed. dqt is a data questioning tool that binds to existing warehouse
columns -- it does not compute metric values.

• Removed dqt.subscriptions module entirely (was an in-memory stub, no real delivery)
• Removed expr_type, expr_sql, numerator_sql, denominator_sql, filter_sql,
  time_column fields from MetricDefinition
• Removed /metrics/evaluate-expression and /metrics/{fqn}/evaluate API endpoints
• Dropped metric_runs table (migration runs DROP TABLE IF EXISTS metric_runs)
• Removed ExpressionBuilder frontend component

Other

• Fixed null crash in tasks page when API is unreachable during static prerender
• Added /api/v1/trigger/history endpoint
• README rewritten to ~130 lines with links to detailed docs
