From 4586e7d3f5be0658824dd85f0f2e941ce5840ae1 Mon Sep 17 00:00:00 2001 From: nerdCopter <56646290+nerdCopter@users.noreply.github.com> Date: Wed, 10 Jun 2026 09:48:06 -0500 Subject: [PATCH 01/14] feat: always-on markdown statistical report per processed file Automatically writes _report.md alongside PNGs on every run. No flag required. Includes firmware/config metadata, per-axis signal statistics (mean/std/min/max/rms for gyro, setpoint, P/I/D/F), and linked (not inline) references to all generated PNG files.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add three new report sections from console output that were missing: 1. Filter Configuration: per-axis LPF1/LPF2/IMUF table + dynamic notch and RPM filter lines. Parses AllFilterConfigs, DynamicNotchConfig, RpmFilterConfig from header metadata via filter_response. Works for BF (unified), EmuFlight (per-axis), HELIOSPRING (IMUF PTn), and EmuFlight pseudo-Kalman. 2. D-term N/A disambiguation: DTermAxisDelay struct replaces Vec>, carrying na_reason alongside the result. Possible reasons: "D gain disabled", "Low signal correlation", "Insufficient samples", "No D-term data". Report now shows e.g. "N/A (Low signal correlation)" instead of bare "N/A". 3. Step response warnings: warnings: Vec on StepAxisReport captures severe overshoot and unreasonable P:D ratio alerts that previously only appeared on console. Rendered as bold "⚠ Warning:" lines after recommendations.

Error propagation: replaced log-and-continue match on generate_markdown_report with ? operator so a write failure propagates out of process_file(). 3. Empty axis_delays in plot_setpoint_vs_gyro.rs: changed Vec::new() fallback to vec![None; AXIS_NAMES.len()] to satisfy the per-axis indexing contract expected by downstream consumers. 4.
