dsh-client-ui-green-meter

Browser surface for dsh-green-meter: the always-visible energy/carbon readout in the composer dock (beside the shipped stats line), the detail panel (per-turn chart, per-request list, totals, cache-savings callout), and the sidebar seat for the panel.

The live value arrives through useProjection('greenMeter') — the greenMeter session projection contributed by the host plugin — so this package owns no store, no refresh chain, and no event listener.

Placement

| panelPlacement | Detail panel location | Requirements | |---|---|---| | popover (default) | floating card above the readout | none — works on vanilla installs | | sidebar | inside the sidebar's blank space | apply patches/ui-sidebar-sidebar-energy.patch to a DeepSeek Harness checkout and rebuild dsh-client-ui-sidebar |

States

| Projection value | Rendered | |---|---| | undefined (host unit not composed) | nothing | | null (no billable steps yet) | the empty state (能耗 —) | | live totals | 能耗 <value> · 碳 <value> g CO2e, refreshed by session/projection pushes |

Model Experience

None — the widget only renders human-facing session energy/carbon figures from the greenMeter projection; it appends no surface events and adds no model-visible content.

KV Cache effect

Independent — reads only projection values, never the request surface.

Known Limitations and Deferred Work

• No per-turn breakdown in the widget — the detail panel shows the per-turn chart and per-request list; /green owns the detailed report.
• Estimate-only figures — the values are token-profile estimates from the host plugin (see its method boundaries).
