Replaces the old 3-panel coresync-frost-demo.json with a 13-panel dashboard
designed for at-a-glance verification of CoreSync's compression behaviour.
Dashboard rebuild (docker/grafana/provisioning/dashboards/coresync-frost-demo.json):
- Header "How to read" text panel: definitions table + sanity checks so
every metric is line-of-sight to its Flux source.
- Scoreboard row (4 stats): raw samples / CoreSync knots / reduction % /
approx. bytes saved over the selected time range.
- Per-stream verification table: one row per CoreSync stream with raw,
knots, and reductionPct (gradient-coloured). Each line's math is
mentally checkable: raw × (1 − reductionPct/100) = knots.
- Signal-reconstruction overlays: flow (m³/h) and pressure (mbar)
rendered as a thin raw line plus fat red knot points so you can see
knots snap to the raw signal at direction changes. Fixes the previous
panels which mislabelled both as `flowm3h` regardless of units.
- Diagnostics row: per-stream knot-interarrival timeseries and a
full-math compression-health table (raw, knots, kept fraction with
gradient bar, savedPct with colour background).
Bumps coresync submodule to 21d77a8 which lands the FROST demo flow plus
the burst-window reducer fix that was driving cog/efficiency/SEC to ~0%
compression. Verified end-to-end on the live stack: headline reduction
went from 33% to 83%, broken streams from 0.6%-14% to 78%-93%.
