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 · 碳 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).
