From 655f6ade833c9c8eb88806d2be94a6104a9043a9 Mon Sep 17 00:00:00 2001 From: InauguralPhysicist Date: Wed, 5 Aug 2026 06:45:47 -0500 Subject: [PATCH] chart: scalar per-point mapping (1.5x at 4k points) + vline/hline ctors; de-flake [62] capture (#828, #876) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #828. Closes #876. - lib/ui_w_viz.eigs: the series hot loop no longer calls _chart_map (a fresh 2-element list per plotted point per frame — ~37% of the frame at 4,000 points by ceiling probe, and an #827 pinning amplifier under armed history). The mapping is inlined scalar with hoisted view factors; every other _chart_map site is cold and keeps the readable form. Measured n=5 medians (4,000-pt points series, dummy driver): baseline 62.7 ms/frame, ceiling 39.6, shipped 42.6 — 87% of the probed ceiling, 1.47x. A [63] check pins the inline mapping to chart_to_pixel's exact floored pixels. - chart_vline(x, label, color) / chart_hline(y, label, color): the same markers without the dead coordinate chart_marker forces callers to invent (#828 part 2). Docs + [63] constructor checks. - tests/test_audio.eigs (#876): an opened capture device that delivers no samples in the bounded poll is an environment statement, not a runtime failure — the delivery-dependent checks now SKIP with the count held constant (the file's existing no-device convention). A delivering device still runs every check against the real driver. This was the unexplained 38-fail suite run: [62] lump-counts. Validated: full suite 3815/3815 against the gfx build; [62] 53/53 in all three modes (delivering device, silent device, dummy driver).
