ChuckBuildsandClaude	105c6df019	Fix IndexError in find_blank_cut when the cut lands on the image edge ... A cut position after the last column is legitimate — _crop_to_budget asks for min(start + budget, img.width), which equals the width whenever the remaining strip is shorter than the budget. find_blank_cut clamped target to width but then walked leftwards starting at target itself, so ink[width] raised IndexError. Caught on hardware: it killed the ledmatrix-stocks fetch, and because _fetch_plugin_content catches broadly that surfaced as the plugin silently contributing nothing for the cycle. Only reachable on the second or later pass of the rotating window over a single oversized image, which is why the existing tests missed it — they all exercised the first pass, where start is 0 and start + budget is comfortably inside the image. Added TestRotationAcrossMultipleCycles, which walks the window round several times and asserts content is never lost, plus direct coverage of find_blank_cut at and beyond the image edge. Both bounds now stop at width - 1 so neither direction can index past the end.

ChuckBuildsandClaude	616d21c6d3	Vegas mode: render plugins narrower, space rows by measured separation ... Trimming reclaims blank margins but cannot compact a layout that genuinely spans the display — a five-column forecast, a progress bar drawn at 100% width, a stat block with the panel's whole width between its elements. Those need the plugin to make different layout decisions, which means telling it the screen is narrower while it renders. DisplayManager.render_size() presents a smaller logical canvas for the duration of a Vegas content fetch, reusing the same _LogicalMatrix indirection double-sided mode already relies on so plugins see a consistent size from every accessor. Plugins that size themselves from matrix.width need no changes at all; one that wants to be explicit can read the new BasePlugin.get_vegas_render_width(). Width is a percentage so a single setting travels across panel sizes: vegas_scroll.render_width_pct globally, or vegas_width_pct in an individual plugin's config. Measured on a 512x64 panel with real data: ledmatrix-weather 1536px -> 576px (forecast becomes narrow cards) youtube-stats 353px -> 199px (2% blank left, so genuinely compact) geochron 453px -> 153px (ink density rises to 100%) ledmatrix-flights 950px -> 740px The youtube-stats figure is the clearest evidence the layout itself changed rather than being cropped: at full width the content had to be trimmed from 512px to 353px, whereas at 40% it arrives with almost no blank to reclaim. Row spacing is now measured rather than added. A flat gap gets it wrong in both directions at once — content drawn flush to its own edges ends up nearly touching (reported for recent sports scores, which sat 8px apart), while content already carrying wide margins gets pushed even further out. separation_gap() measures the blank each pair already has and adds only the shortfall, up to min_content_separation (default 24). intra_plugin_gap stays as a floor applied regardless. Two tests shipped in the previous commit encoded the old flat-gap arithmetic and are updated to the measured semantics, including one renamed to reflect that zero intra_plugin_gap alone no longer butts rows together. Also fixes a real bug found while testing: the harness display manager had no render_size(), and because the adapter catches broadly that surfaced as "no content" rather than an error, silently dropping five plugins. Added the context to VisualTestDisplayManager for parity, and _render_at() now degrades to a no-op on any display manager lacking it, so a third-party or older harness loses the narrowing rather than the content.

ChuckBuildsandClaude	8d57a748a7	Vegas mode: reclaim dead space and pace the rotation ... On a wide panel Vegas mode spent much of its time showing black. At 50px/s on a 512px display, one display width of blank is 10.2 seconds, which makes several long-standing behaviours expensive: - ScrollHelper prepended a full display width of black as an "initial gap", charged once per cycle — 10.2s of black at the start of every rotation. - Plugins without get_vegas_content() are captured off a full-display canvas, so their blank margins entered the ticker too. Measured: of-the-day drew 35px of "No Data" on a 512px canvas (92% blank), youtube-stats 142px of content with 185px of black either side. Only the scroll_helper path had any trimming. - Cycle transitions deliberately pushed a blank frame and then recomposed synchronously: 84ms at best, 4.8s at worst, every millisecond of it black. - buffer_ahead doubled as the cycle size, so a 21-plugin install showed 3 plugins per cycle and took ~7 cycles to come around. - separator_width was applied between every image rather than at plugin boundaries, so a per-row ticker like the F1 scoreboard (116 images, which it renders 4px apart internally) got a 32px chasm between each row — and the width budget didn't count those gaps, so the plugin quietly occupied far more of the panel than intended. Changes: - src/vegas_mode/geometry.py: numpy column-ink primitives shared by the trimmer and the audit tool, so the number reported is the number acted on. A Python per-column loop over a 17,000px strip is far too slow for the render path. - PluginAdapter trims every content path, not just scroll_helper. Only outer edges are cropped: interior blank columns are the plugin's own layout (logo left, score right) and closing them would corrupt the design. A plugin on a non-black background is inherently unaffected. - ScrollHelper.create_scrolling_image takes an explicit lead_gap, still defaulting to display_width so the many standalone-ticker callers are unchanged. Vegas passes lead_in_width (default 0). - Cycle end holds the last rendered frame instead of blanking, turning the recompose into a brief freeze rather than the panel switching off. - plugins_per_cycle (default 6) is split from buffer_ahead, which goes back to being only a prefetch low-water mark. - max_plugin_width_ratio (default 3x display width) caps one plugin's share of a cycle. Overflow is deferred, not discarded: a rotation offset advances each fetch so later rows appear on subsequent cycles. Single oversized images are cropped at a blank column so the cut misses glyphs. - Composition groups images by plugin: rows are joined by intra_plugin_gap (default 8) and separator_width applies only between plugins. The width budget now counts those gaps. - Plugin data updates no longer run on the Vegas render path. All new settings are user-configurable in Display -> Vegas Scroll, including min/max cycle duration and dynamic duration, which previously existed in code but were reachable only by hand-editing config.json. Measured with scripts/dev/vegas_audit.py on a 512x64 panel: mean ink coverage 42.7% -> 69.4% fully blank 5.9% -> 0% reads as empty 13.6% -> 0% worst blank stretch 4.8s -> 0s full rotation 414s -> 123s plugins per cycle 3 -> 6 Note the metric choice: a "fully blank" scan (>=95% black viewport) reported only 0.4% and badly understated the problem, because two full-width segments with mid-canvas content never fully blank the viewport — they hold it at ~28%. window_coverage_stats grades every viewport position by how much ink it carries, which is what tracks perceived dead time. Known remaining: cycle transitions still freeze ~3.5s while the next cycle is fetched. Fixing that needs background prefetch, which is deferred because the fallback-capture path mutates the shared display_manager.image and racing it against the render loop risks torn frames.
