ChuckandClaude Opus 5.5 f79618d4f7 refactor(bench): grade render_bench with the shared frame-timing recorder
render_bench.py (from the parallel perf/render-bench work) had its own
grading module, frame_pacing, with its own definition of a missed frame
and its own refresh estimate. The soak already had both in frame_timing,
so the two could have drifted apart on what "late" means.

The bench now gives the display manager a fresh FrameTimingRecorder,
drains it synchronously at the start and end of the graded run, and prints
frame_soak's report with frame_soak's verdict. Its workload is unchanged:
the synthetic strip, --busy load, the shared speed resolver, the
per-frame scrolling announcement. frame_pacing, its tests and its
src.common exports are removed; measure_refresh_hz moves to frame_timing,
where scroll_speeds.py now finds it.

Two ideas from frame_pacing carry over. The bench seeds the recorder with
the idle refresh it measures, so a loop that free-runs (the 827fps bug
the first bench caught) shows as early frames and one stuck at half rate
as late frames, where an estimate taken from their own intervals finds
both self-consistent. And the soak, which has no idle measurement, now
calls a run NOT LOCKED when its refresh estimate beats the configured cap.
The report also gives the rate held while rendering.

Docs: the bench becomes "Without the service" under "Soaking a rig",
keeping its hdpi numbers and the idle-vs-rendering refresh finding.

LEDMatrix Documentation

This directory contains guides, references, and architectural notes for the LEDMatrix project. If you are setting up a Pi for the first time, start with the project root README — it covers hardware, OS imaging, and the one-shot installer. The pages here go deeper.

I'm a new user

  1. GETTING_STARTED.md — first-time setup walkthrough
  2. WEB_INTERFACE_GUIDE.md — using the web UI
  3. PLUGIN_STORE_GUIDE.md — installing and managing plugins
  4. WIFI_NETWORK_SETUP.md — WiFi and AP-mode setup
  5. TROUBLESHOOTING.md — common issues and fixes
  6. SSH_UNAVAILABLE_AFTER_INSTALL.md — recovering SSH after install
  7. CONFIG_DEBUGGING.md — diagnosing config problems
  8. LOW_MEMORY_BOARDS.md — Pi Zero 2 W / 3B+ / 1GB Pi 4 memory limits

I want to write a plugin

Start here:

  1. PLUGIN_DEVELOPMENT_GUIDE.md — end-to-end workflow
  2. PLUGIN_QUICK_REFERENCE.md — cheat sheet
  3. PLUGIN_API_REFERENCE.md — display, cache, and plugin-manager APIs
  4. PLUGIN_ERROR_HANDLING.md — error-handling patterns
  5. DEV_PREVIEW.md — preview plugins on your dev machine without a Pi

Contributing to the docs

  • Markdown only, professional tone, minimal emoji.
  • Prefer adding to an existing page over creating a new one. If you add a new page, link it from this index in the section it belongs to.
  • If a page becomes obsolete, delete it (it stays in the repository history) and fix the links to it; test/test_doc_links.py fails on broken relative links.
  • Keep examples runnable — paths, commands, and config keys here should match what's actually in the repo.
