Summary

• Label usage without a workspace link as Unassigned usage and explain organization-level activity and permanently deleted workspaces in a hover/click disclosure. Align its values with the workspace rows.
• Refresh usage charts with flat, softer colors, quieter gridlines, and readable axis intervals while preserving source color identities.
• Add a daily credit heatmap below the chart for organization and workspace views. Load its 365-day history separately, with timezone-aware dates, exact values, and keyboard navigation.

Type of Change

• Enhancement and bug fix

Testing

• Root lint, type-check, check:audits, check:test-types, block-registry audit, and full test suite.
• Focused billing/calendar tests and the EMCN test suite, including aggregation before rounding, paid sub-credit days, DST, leap years, midnight boundaries, and chart scales.
• Browser verification of the actual chart components with fixture data: dark/light themes, 320px and 390px layouts, legend isolation, keyboard navigation, click disclosures, sub-credit heatmap cells, and the latency-axis zero baseline. The updated Insights guide compiles as MDX.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

• In bar-chart.tsx, latency charts show — instead of 0 at the baseline. Preserve a literal 0 for the zero tick.

<file name="packages/emcn/src/components/charts/bar-chart.tsx">

<violation number="1" location="packages/emcn/src/components/charts/bar-chart.tsx:130">
P2: The zero tick is passed through `formatBarValue` for `unit='latency'`, but `formatChartLatency(0)` returns `—`; latency bar charts therefore label the baseline as missing instead of `0`. Preserve a literal `0` for that tick.</violation>
