RuView: Getting Multi-Node CSI Sensing to Actually Agree
All seven pull requests trace back to one root problem — nodes in the mesh sensing fleet were measuring different things while appearing healthy, and this week's work made that failure mode visible, measured, and fixed at the clock, the rate counter, and the data model.

Good morning. It's September 8th, and this is RuView.
The signal today is a single, well-documented failure pattern: independent nodes in a multi-node sensing fleet can each report healthy status while silently disagreeing about what they measured. Four separate fixes trace back to that one root cause.
Start with timing. PR 1859 found that each node's CSI rate gate ran on its own clock, accepting frames every 20 milliseconds — but out of phase with its neighbors. Both nodes hit the same rate, both looked fine, but they never captured the same transmission at the same time. Cross-node fusion had nothing to pair.…
Related and just as subtle: PR 1857 found the server's frame-rate counter under-reports whenever frames arrive in a burst — the anchor point doesn't reset, so a burst of many frames gets counted as one. And PR 1860 caught a data-modeling bug of the same shape: node positions were keyed by list position but read back…
The through-line: this system's hardest bugs are the quiet kind — heartbeats stay green while the underlying data drifts. PR 1862 documents the reasoning trail behind these fixes as a formal decision record, and PR 1861 adds an operational runbook for the…
