The evolution of a flight recorder
summary
A tiny library replaces printf/log lines with a few C source files (add two files as a submodule) and records events into lock-free circular buffers (one implementation uses a 128KB ring) so you can dump recent history on crash. It exports selected numeric traces to shared memory and a little viewer (ricotta scope) for real-time graphs, and uses trace flags as live config knobs (including a remote slider) to tweak running SPICE and camera code — and it proves useful in practice.
