Random and Sequence are mutually exclusive + 293→// (ticking either one unticks the other; both share the same + 294→// delay and folder scope), Random now never loads the same preset + 295→// twice in a row, and Sequence holds its breath through silence + 296→// exactly like Random does. The Demo showcase now runs SEQUENCE — + 297→// the one play-through walks every Zai-Magic preset in order + 298→// (20 s each) rather than repeating random picks, and when the + 299→// demo stops, whichever mode it checked is unchecked again + 300→// 7.3 — demo-flow refinements: the Demo Track is a single pass — it plays + 301→// "Neural Mecha Pulse" once through and stops (a demo, not a radio + 302→// station). However it ends (natural finish, Stop, or switching to + 303→// another source) the showcase unwinds: the randomizer the Demo + 304→// flow force-checked is unchecked again, and the visitor lands + 305→// back on the "Select an audio source" overlay. Preset-change + 306→// popups are gone ("Preset loaded" / "Random preset" / "Default + 307→// preset running") — the footer's SCRIPT: label already echoes + 308→// every change, so the toasts were pure intrusion; only compile + 309→// errors still toast. Club-mode randomizer now respects silence: + 310→// when no music is playing it never re-shuffles the selected + 311→// preset, even with the checkbox on — it waits for the next track + 312→// 7.2.1 — Supernova (Zai-Magic) preset fix: the particle kill condition + 313→// (|px|+|py| > 2.4) was physically unreachable — drag caps a + 314→// particle's total travel at vel/1.6 ≈ 1.0, so nothing ever + 315→// crossed 1.4, nothing ever died, and since respawning requires a + 316→// dead particle, the per-beat "budget = n" detonation could never + 317→// fire after the initial one — the preset exploded once on load, + 318→// then faded to permanent black. Now every beat force-clears the + 319→// whole 620-particle field in [beat] (guaranteed full re-detonation + 320→// on the very same frame), fully-cooled particles die by fade so + 321→// long beat gaps leave a gentle ember drizzle instead of black, + 322→// and each blast re-randomizes its geometry (no two explosions + 323→// alike).

All behavior is stateless script math (deterministic rand-seeded parabolas), so it is fully deterministic and reproducible; the library re-seed delivers it to every visitor, and the old white-rain version is gone. + +--- +Task ID: 43 +Agent: main (Z.ai Code) +Task: v7.14.1 (user request, Brainstorm preset session 3): the user tested the Brainstorm color-shift + blow-out script on their VPS and reported the blow-out FADED -- they wanted the colors to keep moving outward at constant speed and be REPLACED by new color at the center, never fading. Engine request: support a no-fade mode and additional blend modes (subtract, multiply, additive, replace, etc.). + +DESIGN: +- The fade could not be tuned away: the persistence fade is a per-frame black fill (engine.ts loop), and persist was hard-capped at 0.98 (parser) / 0.985 (engine). A feedback blow-out therefore ALWAYS decayed. +- blend: replace = canvas 'source-over' with the CORE pass at FULL alpha (lines gain 1.0 instead of 0.9; dots alphaGain 1.0 instead of 0.85; solid fill alpha 1.0 instead of 0.65; halo pass 0.25): fresh strokes overwrite the pixels under them, so a figure redrawn over its own accumulating trails keeps its color instead of saturating to white. source-over can never exceed the source color, so nothing accumulates past what the script paints. +- blend: subtract = canvas 'difference' (|dst - src|): Canvas2D has no clamped true-subtract composite; difference is the classic approximation and shares the property the mode exists for -- it can never climb to white. +- blend: multiply / screen = the canvas composites of the same names; additive/alpha unchanged. +- persist widened 0..0.98 -> 0..1 (parser clamp + error string) and 0..0.985 -> 0..1 (engine clamp); at exactly 1 the fade fill is SKIPPED entirely -- a true zero-fade framebuffer. Old content then leaves the screen only through a bg* transform carrying it off-screen (or a replace repaint), which is exactly the user's model: "the blow-out itself is the cleanup". + +Work Log: +- types.ts: BlendMode union extended to 'additive' | 'alpha' | 'multiply' | 'screen' | 'subtract' | 'replace' with a doc comment. +- script.ts: BLENDS set + header doc + error message list all six; persist range 0..1 with the v7.14.1 comment. +- engine.ts: BLEND_COMPOSITE map (blend -> GlobalCompositeOperation) replaces the old additive ternary; persistence block clamps to 1 and skips the fill at persist === 1; per-mode replace gains in the lines/dots/solid passes; file-header comment updated. +- help-panel.tsx: persist var doc (0..1, 1 = never fades) + .ava format block (blend list, persist range). +- version.ts: APP_VERSION 7.14.1 + full history entry. release-notes.ts: 7.14.1 "New blend modes + zero-fade trails" (2 added items, first-person voice). +- No library changes (EMBEDDED_SEED_VERSION stays 7.14; all 106 presets keep additive/alpha and their persist values -- verified untouched). + +HEADLESS VALIDATION (/home/z/tmp-validate/blend/validate.mts, REAL parser/compiler, 33/33 PASS): +- Library regression: all 106 presets compile; zero presets re-interpret blend or shift persist past 0.98. +- All six blend values accepted (additive, alpha, multiply, screen, subtract, replace); 'lighten' and '' rejected; the invalid-blend error lists all six. +- persist parse/clamp: 1 -> 1, 1.5 -> 1, 100 -> 1, 0.985/0.98 unchanged, -0.5 -> 0; bad-persist error says 0..1. +- The v7.14.1 Brainstorm script end-to-end (240 frames x 584 points, engine env conventions): no runtime errors, all positions finite, all colors in range, bgzoom constant 1.035 every frame, bgrot magnitude constant 0.015, dir flips on 5/5 beats, hue advances 0.551 over 5 beats (~0.11 each). + +BROWSER E2E (agent-browser, ALL PASS): +- Fresh load: title "OVE -- Open Visualization Engine (v7.14.1)". +- ZERO-FADE PROOF: dots field that draws 90 frames then skips forever -- brightPct 87.6% at t=3s AND 87.6% at t=15s (13.5s after drawing stopped), maxLum 240.
