216→// the body's alphabet back from a ~32-character bitmap header
|

217→// instead of ~80 literal symbols. Short scripts where the header

222→// (best 22%), e.g. Bass Bloom 1341 → 326 characters
|

223→// 7.7 — script sharing + settings declutter. Script⇢Hash / Hash⇢Script:
|

224→// two buttons in the Script tab turn the editor's script into ONE

227→// for ANY text, compiling NOT required, so WIP scripts can be

229→// references (♤ = line return, ♡ = beats, ♠ = beatage, ♦ = space,
|

230→// ♩♪♫♬ = the four sections, one symbol per function/variable, plus
|

231→// a pair-packing layer that folds leftover identifier/number text
|
||||
232→// two chars per CJK code point) — ~50% shorter than the script on
|
||||
233→// real presets. Copy-safe by construction (no raw whitespace or
|
||||
234→// control chars; platform-injected variation selectors / zero-
|
||||
235→// widths stripped on paste) and self-checking: 8 check digits (an
|

236→// FNV-1a digest rendered as ①–⑯) reject strings that were cut off
|

237→// by a character limit or altered in transit, instead of decoding

242→// 7.6.1 — header declutter: the Set Beat button is gone from the header

244→// anywhere — both unchanged). The beat indicator dot stays.
|

245→// 7.6 — "What's New!" dialog: a Sparkles button in the header (left of

255→// 7.5.1 — Link dialog width fix: text no longer escapes the dialog box.
|

256→// Root cause: Radix dialogs lay their children in an implicit CSS
|

257→// grid whose single column sizes to the widest child's min-content;
|
||||
258→// the RECENT LINKS rows carry truncate spans (white-space: nowrap),
|

259→// and Chromium measures a nowrap flex item's full text width for
|
||||
260→// that measurement — so a long saved title (e.g. "Bobby Foxx — This
|
||||
261→// Is Why We Can't Have Nice Things (Official Music Video)") blew
|
||||
262→// the column ~40 px past the 448 px dialog, and EVERY child (title,
|
||||
263→// description, input + Load, rows, footer) laid out beyond the
|
||||
264→// right border. Fix: the shared Dialog/AlertDialog content now pins
|
||||
265→// the column to minmax(0,1fr) — capped at the available width, so
|
||||
266→// no nowrap content can ever stretch a dialog again (covers every
|
||||
267→// dialog app-wide) — the Link dialog widened to max-w-lg for
|
||||
268→// comfier wrapping, and min-w-0 + break-words added on the
|
||||
269→// recents/playlist containers and error text as belt-and-braces
|
||||
270→// 7.5 — yt-dlp compatibility: single tracks resolve by DOWNLOAD + CONVERT
|
||||
271→// instead of proxying the extractor's stream URL. The old stream
|
||||
272→// URLs were IP-locked (googlevideo bakes in the resolver's IP),

277→// --audio-quality 0 -o "<dir>/%(title)s.%(ext)s" URL
|

278→// — audio-only download, universal MP3 at VBR-0 (~245 kbps), the
|

279→// video's real title preserved for the Playing: label. The
|
||||
280→// finished file streams same-origin with full Range support from
|
||||
281→// a per-track workspace dir (30-min sliding TTL + orphan sweeper);
|
||||
282→// /api/audio/stream gained a file-serving mode. Hardening around
|
||||
283→// it: shared failure classifier for both yt-dlp passes (metadata +
|
||||
284→// download), 180 s download budget, 300 MB cap, bot-wall/stale-
|
||||
285→// extractor answers unchanged, ffmpeg-missing degrades to the old
|
||||
286→// proxy path (logged once), queue look-ahead lead 15 s → 60 s so
|
||||
287→// playlist transitions don't stall behind conversions
|
||||
288→// 7.4 — Sequence mode: a second mix checkbox next to Random. Ticked, it
|
||||
289→// cycles the scope folder's presets IN ORDER (the tree's exact
|

290→// top-to-bottom order) instead of shuffling — and when it moves
|

291→// past the last preset it wraps back to the first, so the folder
|

292→// loops forever. 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
|

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). Embedded library re-seeded (seed marker 7.01)

326→// (previously royal purple + yellow), and Zai-Magic "Bass Bloom"
|

327→// as the startup preset (previously the first Synth-C classic).
|
||||
328→// The idle overlay's Demo Track button now carries an animated
|
||||
329→// reflective shimmer (skewed light band sweeping left→right every
|

330→// 3.2 s, reduced-motion safe) to draw the click — and that one
|
||||
331→// click starts the full showcase: the demo track plays while the
|
||||
332→// preset tree selects + expands Zai-Magic, randomize switches on
|
||||
333→// scoped to that folder with a 20-second change interval. Music
|
||||
334→// started with NO preset active (own draft running / selection
|
||||
335→// cleared) auto-loads Bass Bloom. Preset changes — manual load,
|
||||
336→// the random mix, the Demo flow — no longer hard-cut: the engine
|

337→// snapshots the outgoing frame and blur-dissolves it into the new
|
||||
338→// preset over 700 ms (progressive blur + easeOutCubic fade + a
|

339→// slight scale-up so the softening edges never gap; plain
|

340→// crossfade where ctx.filter is unsupported)
|
||||
341→// 7.1 — real demo track + a beat detector that survives real music.
|
||||
342→// The Demo button now plays "Neural Mecha Pulse" (the operator's

Stage Summary:
|
||||
- v7.14 shipped: Arctic Rainbow is now a music-driven water spray -- slow parabolic rises, left/right arching falls, drop count tracking the music's intensity (dry silence), per-drop bass-hit hue shifts, and tapered RGB tails that appear only on the way down. 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. Under the old 0.985 cap it would have been ~0% (0.985^810 ~= 5e-6).
|
||||
- FADE-PATH REGRESSION: the same script at persist 0.859 -> brightPct 0.00% 1.5s after drawing stopped (normal fading fully intact).
|
||||
- REPLACE PROOF: rotating ring (1, 0.7, 0.4) at persist 1, after 10s of repainting over itself the brightest ring pixels average RGB [255, 178, 101] = the EXACT script color, zero white-clamped pixels. Contrast run with blend additive: [255, 255, 255] with 25,064 white-clamped pixels -- the modes genuinely differ and replace does not advance to white.
|
||||
- v7.14.1 Brainstorm on the demo track (FPS 56-60, PTS 584, BPM locked 132.9-142.5): radial-band analysis shows 100% bright pixels in ALL annulus bands 0.1-1.1 with age-shifted colors (teal center -> green outer = old hues riding outward); 5s later the center band color flipped cyan [4,133,171] -> magenta [161,0,199] while staying 96.8% bright = new color replacing old at the center, old color riding out. VLM: kaleidoscope flower at center, blow-out wedges to all edges, multiple distinct hues at different radii, nothing washed to white, no glitches.
|
||||
- Stock library Brainstorm (additive, 0.859) applied: classic near-white flower with fading trails to black edges (VLM-confirmed geometry + fade; its white/gray tone is the script's own color math, r=g=b coefficients -- the stock hue var is unused), FPS 59 -- old presets render byte-for-byte as before.
|
||||
- What's New: 7.14.1 "New blend modes + zero-fade trails" first with CURRENT badge, both items present. Console 0 errors / 0 warnings. Responsive: 375x812 no horizontal overflow; 1280x800 footer at viewport bottom (docH 800 = innerH). Test-browser localStorage cleared afterwards.
|
||||
|
||||
Stage Summary:
|
||||
- v7.14.1 shipped: the script engine grew a real composite family (multiply, screen, subtract, replace) and a true zero-fade framebuffer (persist 1 skips the fade pass). The pairing the user asked for -- blend replace + persist 1 + bgzoom/bgrot feedback -- now renders a static-speed blow-out that never fades: colors ride outward at full brightness and the fresh drawing replaces the old color at the center. All existing presets keep their exact behavior (regression-verified headlessly and in-browser); the updated Brainstorm script was delivered to the user for VPS testing.
