Breaking: Series::gather emits x relative to x0() and takes a GatherMode; consumers reconstruct absolute x in f64 before mapping (series.hpp documents the contract). Bugs, each pinned by a fail-before regression test: - render: f32 staging quantised epoch-time x into 128 px columns; every data-space draw now stages to_space(x) - to_space(origin) with the origin folded into the offset uniform in f64 (epoch/zero-origin twins rasterise identically) - ticks: major test was ULP-fragile and blanked epoch axes; majors are an integer-index test and are never truncated by the minor cap - gather: LOD envelope emitted buckets straddling [begin,end); ceil/floor bucket edges + raw lead/trail spans - live follow: log x axes held a linear span and zoomed every frame; span and offset now live in axis space (plot + both figure link-group paths) - input: a zero-notch wheel disarmed auto_scale on every axis; dy==0 pans x, factor == 1 / inf refused in wheel and drag zoom - render: the single text flush painted legend names over the crosshair readout panel; two batches, under flushed before the panel - data: NaN dropped from min/max unless it seeded the fold; non-finite samples are now excluded from every aggregate and from cached bounds Robustness: viewport normalisation (no clamp UB), non-finite range refusal, pyramid level cap at 57 (no shift/div UB through public gather), rounded ring capacity documented + pre-sized, GL blend func and UNPACK_ALIGNMENT save/restore, Renderer::release_gl() teardown, u64 buffer epochs, annotation captions clamped, button-aware GLFW row capture, cached figure row rects (no per-event layout), ruler-pair measurement refused, span-nonfinite guards in axis_ends. Features: XY series (sorted x, binary-search neighbours/snap, LOD over sample index); StreamSeries::freeze(); ArraySeries::push(); per-trace dash and markers (scatter at width 0) with auto or literal stride; GatherMode Envelope/Nearest/Mean via bucket_sum/sumsq; Style::line_aa_px; per-glyph text colour (readout values in trace colour); wheel-dx x pan; arrow-key pan; Escape cancels a drag and restores captured ranges; modifier-masked box zoom (Shift both, Ctrl x, Alt y); double-click reset via PointerEvent::time_s; ImGui key repeat unified; pinch gestures on Qt and GTK; pixelDelta wheel path and DevicePixelRatioChange handling; GNUInstallDirs, SOVERSION, SameMinorVersion, generated plot/version.hpp, relocatable plot.pc, licence install, FILES_MATCHING, GitHub Actions CI (debug/coverage/asan). Suite 283 -> 350 cases, 0 failed; coverage 93.9% (3730/3971) over 24 files, floor 80/90 held; ASAN preset suite green; all four demos run headless (the GTK scripted-resize check needs a window manager and fails identically on the parent commit); readme_main.cpp committed and compiles with the README command; pkg-config and find_package consumption verified from a relocated install prefix.
