2200→- Round-trip EXACT on 207 scripts (90 tools/converted .ava + 6 rust-agent presets + presets.ts inline + 105 DB built-ins): 136,046 → 69,523 chars = 49% shorter overall (best 56%, worst 28%); determinism verified per script.
|
||
2201→- Adversarial "soup" (every reserved symbol, all card suits, chess, zodiac, arrows, circled digits, control pictures, backslashes, CRLF, raw control chars, VS16/ZWJ sequences, emoji incl. ZWJ families, combining marks, surrogate edges): exact round-trip.
|
||
2202→- 3,000-string fuzz over a hostile alphabet: 3,000/3,000 exact. CJK-comment scripts (colliding with the pair-packing block) and literal pair-block content round-trip via the escape path.
|
||
2203→- Decode rejects: truncation (−1/−5/−20 chars), flipped body char (checksum), garbage/empty/malformed inputs; accepts: padded+quoted, bare body, VS16+ZWSP mangled (injected between EVERY char), name with colons/brackets (sanitized), >48-char names (capped).
|
||
2204→
|
||
2205→BROWSER E2E (agent-browser + VLM, ALL PASS):
|
||
2206→- Script tab shows both buttons; Script⇢Hash opens with `Bass Bloom:[▲…③⑬⑧⑭①⑧⑩⑪]` — 679 chars, "49% shorter than the script", semantic symbols + CJK pairs visible; Copy click → "Copied!" (clipboard API present).
|
||
2207→- Full UI round-trip: hash captured → Hash⇢Script pasted → Decode → panel "Bass Bloom · 56 lines · 1341 characters · Compiles OK — mode: dots" → Load into Editor → editor content BYTE-IDENTICAL to the original (1341/1341 chars, string equality true).
|
||
2208→- Errors: garbage → "does not look like an OVE share string…"; truncated (−15, loses "]") → "looks cut off — it should end with "]" (signature-based message); altered → checksum message.
|
||
2209→- Re-open resets paste state (bug fix verified); Settings tab: no Music services section/heading/log-in buttons, Appearance intact (visible panel text verified).
|
||
2210→- Mobile 375 px: toolbar wraps with both buttons on-screen, no horizontal overflow; both dialogs fit (16–359 px wide, Script⇢Hash 69–743 px in 812 px viewport after the height-cap fix; textarea ≤ 240 px, scrolls internally). 320 px header: scrollWidth 320 = clientWidth (v7.6.1's removal fixed the old ≤360 px overflow — re-measured as promised).
|
||
2211→- VLM (dark, Script⇢Hash): nothing crosses the border, string/symbols/ Copy/stats all present, readable, no defects. VLM (light, Hash⇢Script): title, placeholder "My Script:[▲…]", Cancel/Decode well-formed, contrast good on white. VLM (mobile): fully visible, nothing cut off.
|
||
2212→- Fresh reload: console 0 errors/0 warnings (release-notes drift guard silent — v7.7 entries match); dev.log clean (compile + 200s only). Test-browser localStorage cleared afterwards.
|
||
2213→
|
||
2214→Stage Summary:
|
||
2215→- v7.7 shipped: scripts are now shareable as single Unicode strings — ~half the length of the script, self-checking, copy/paste-survivable, lossless for ANY text (compiling not required) — and the Settings tab is decluttered while the house account keeps Stream-a-Link working for everyone. The shared dialog height cap protects every dialog app-wide from tall content on short screens.

|
||
2220→Task: v7.10.1 (user report while testing their new "Spectrum Bars" script): a section on the very right of spectrum visuals is inactive and never reacts to the music -- same dead right edge on other spectrum scripts. Explain why, then fix it engine-side so every script benefits.
|
||
2221→
|
||
2222→DIAGNOSIS (why the right edge is dead):
|
||
2223→- getspec()/sv mapped bar position 0..1 across the WHOLE FFT: bin = 2 + floor(p^1.6 * 4093) at 8192-point FFT, so pos 1.0 = bin 4095 = Nyquist (22.05/24 kHz). pos 0.8 already lands at ~16.8 kHz.
|
||
2224→- Real music carries almost nothing up there, and every lossy source low-passes even lower: the demo collection is 192 kbps MP3 @48 kHz (LAME low-pass ~18.6 kHz), YouTube AAC ~15.5 kHz. Measured on demo-01 (20 s, 8192-FFT): 0.000% of total magnitude above 18.6 kHz; content above -40 dB rel. peak ends at ~13.4 kHz, above -60 dB at ~17.8 kHz.
|
||
2225→- So bar positions above ~0.82 read byte 0 every frame -- the rightmost ~20% of every spectrum visual was permanently frozen at the floor. Not a script bug: every script sampling getspec over 0..1 (all 10 converted getspec presets included) showed the same dead edge, exactly like the Winamp AVS originals. The engine's own flux detector already caps at 16 kHz for the same reason (audio.ts getBands).
|
||
2226→
|
||
2227→Work Log:
|
||
2228→- src/lib/ava/audio.ts: new SPEC_TOP_HZ = 16000 const (with the full why-comment); getSpectrum() now maps the field from bin 2 (~12 Hz) to the 16 kHz bin instead of Nyquist: hiBin = clamp(ceil(16000/binHz)), bin = 2 + floor(p^1.6 * (hiBin - 2)). Same log-ish curve, every position now lands on frequencies music occupies; right edge = 12-16 kHz "air" band (cymbals/hats/sparkle). Matches the flux cap.
|
||
2229→- rust-agent/src/spectrum.rs: SPEC_TOP_HZ const + spectrum_at() mirrors the new mapping exactly (source parity; not compiled locally, no cargo).
|
||
2230→- help-panel.tsx: sv entry now states the span: "spectrum magnitude 0..1 (≈12 Hz to 16 kHz, log-ish -- the range music actually occupies)".
|
||
2231→- version.ts 7.10.1 + history entry; release-notes.ts 7.10.1 "Spectrum edge unfrozen" (fixed, first-person voice). lint clean; tsc clean apart from the pre-existing base-target share-codec BigInt literals.
|
||
2232→
|
||
2233→VERIFICATION (three independent measurements):
|
||
2234→- Offline full-track emulation (Blackman window + AnalyserNode dB byte mapping, every 21 ms of demo-01): under the NEW mapping every one of 48 bars is >15/255 in 76-100% of frames and >60/255 in 68-99% -- nothing is structurally dead. Under the old mapping positions >0.82 read literal zero.
|
||
2235→- Fresh in-page chain (eval: fetch demo-01 -> decodeAudioData -> own AnalyserNode at t=150 s): top positions dance (pos 1.0 = 16 kHz fluctuates 4..118/255 frame to frame).
|
||
2236→- Live E2E with the USER'S OWN "Spectrum Bars" script (found in the test browser's localStorage from the previous session, 28 bars x 4 pts, running on Demo Track 2 at 60 FPS): per-bar pixel measurements across 6 frames show the rightmost bars (f 0.74-1.0 = 9.9-16 kHz) swinging 4%..76% with the music -- under the old mapping those bars sampled 16.8-24 kHz and sat pinned at 0 (the script's own below(lvl,0.004)?0 snap would hold them perfectly flat). Also verified with a purpose-built 48-bar "Edge Check" script earlier in the session.
|
||
2237→- Anomaly chased and closed: one 5-sample window showed bars 36-48 at floor while bass danced -- turned out to be the demo track's outro (offline analysis: t=187-191 s has a legitimately dead 10-16 kHz band while lows keep going); the demo ended right after (SRC: IDLE, place advanced), matching the timeline. Not a mapping issue.
|
||
2238→- What's New dialog: v7.10.1 "Spectrum edge unfrozen" first with CURRENT badge + FIXED tag; drift guard silent after a clean reload (one transient guard warning was hot-reload event ordering + stale console history); the one hydration error was agent-browser's own data-__ab-ci instrumentation, absent on a clean reload. Console otherwise clean; dev.log clean.
|
||
2239→- Test-browser localStorage cleared afterwards (convention); scratch PCM deleted.
|
||
2240→
|
||
2241→Stage Summary:
|
||
2242→- v7.10.1 shipped: the frozen right edge of every spectrum visual is unfrozen. The bar field now spans ~12 Hz to 16 kHz (the range music actually occupies) instead of stretching to Nyquist, so the right bars land on the 10-16 kHz air band and dance with the hats/cymbals. The user's own Spectrum Bars script (whose 0.78+0.45*f treble tilt now has something real to boost) verified live: rightmost bars swing 4..76%.

2247→Task: v7.11 (user request, three parts). RESTORED RETROACTIVELY — the entry was lost in a session cutoff (same as Task 35 once was); scope reconstructed from the version.ts 7.11 history and the tool-results/v711-* evidence screenshots (v711-01 through v711-22, all PASS). (1) Mobile wake lock: while any audio source is live the site holds a Screen Wake Lock so phone/tablet screens stay on; released the moment the engine goes idle so normal inactivity dimming returns. (2) A respectful Demo Track button: no longer force-engages the Sequence checkbox when the visitor has loaded a preset (tree double-click / Load / copied preset) or brought their own script material into the editor — Demo just plays the track; the Zai-Magic showcase only starts for a visit that never picked or typed anything. (3) Script tab one-click Save: a valid script shows the Save button with no save target needed; auto-names from the script's name header (a hash import of "Spectrum Bars:[▼…]" saves as "Spectrum Bars"), "Empty Name" when nameless, " (1)"/" (2)"… suffixes on conflicts — and when the name had to be invented, a "Give This Preset a Name" dialog opens to rename the just-saved preset in one step (saved FIRST, renamed second, so nothing is ever lost).
|
||
2248→
|
||
2249→Work Log (reconstructed):
|
||
2250→- src/lib/ava/wake-lock.ts (NEW): Screen Wake Lock sentinel manager — acquire on source-live, release on idle, visibilitychange re-acquire (browsers silently drop the sentinel on hide), silent degradation where unsupported.
|
||
2251→- audio-source.ts / control-panel / page.tsx: per-visit manualChoice flag + boot-script snapshot decide whether the Demo showcase may engage; ensureDefaultPreset gained the same guard (mic/file/link never clobber a custom draft either). Demo teardown paths (ended/stop/switch) all respect it.
|
||
2252→- script-tab.tsx: Save button visible on any valid script with no target; auto-naming ladder (script name header -> hash import label -> "Empty Name" -> conflict suffixes); "Give This Preset a Name" dialog after any invented save. Hash⇢Script imports clear the stale save target and pass the decoded label through as the fallback name.
|
||
2253→- version.ts 7.11 + history; release-notes.ts 7.11 entry.
|
||
2254→
|
||
2255→E2E (evidence: tool-results/v711-01..22, ALL PASS):
|
||
2256→- Fresh boot (no selection, no editor material): Demo engages the sequence showcase as before — v711-19/20.
|
||
2257→- Preset loaded first (double-click, v711-03; embedded, v711-04): Demo plays the track, Sequence stays UNCHECKED (v711-06), the running script is untouched — a custom script can be debugged against the demo track without fear of replacement (v711-05 custom material case).
|
||
2258→- Hash⇢Script -> Save: lands under "user created" as "Spectrum Bars" from the share-string label (v711-09/10/11); nameless script saves as "Empty Name" then the rename dialog appears (v711-12/15); duplicate conflicts get " (1)"/" (2)" suffixes (v711-16/17) and the rename updates the saved preset (v711-13).
|
||
2259→- Default boot script + reload states (v711-18); mobile 375 px (v711-21) and desktop (v711-22) clean; wake lock verified by code path (headless browsers do not expose navigator.wakeLock — degrade-silent branch exercised).
|
||
2260→
|
||
2261→Stage Summary:
|
||
2262→- v7.11 shipped: the screen stays on while music plays, the Demo button stopped hijacking the preset selection, and one click saves any valid script with a smart name. This restored entry closes the gap in the build diary.

|
||
2267→Task: v7.12 (user request): add the classic-AVS background-movement family to the scripting — the background shifts up/down/left/right, spins clockwise/counter-clockwise, draws in and blows out, with the speed accelerating to the beat and hard hits flipping the spin direction while the fade to black stays slow (so colors blend) — then ship a permanent Zai-Magic preset "osc-rotations": a stationary centered oscilloscope whose left/right points color-shift together and whose center points hold their own hue, over a background rotating cw/ccw to the music with temporary beat acceleration.
|
||
2268→
|
||
2269→Work Log:
|
||
2270→- src/lib/ava/engine.ts — NEW background feedback transform (the AVS movement family):
|
||
2271→ * Script controls, read from env AFTER [frame]/[beat] run so this frame's values apply this frame: bgrot (radians/frame, + = CLOCKWISE on screen — canvas y is down so ctx.rotate(+) spins cw), bgx/bgy (per-frame drift, the -1..1 screen convention, y is UP matching script x/y), bgzoom (per-frame scale: <1 draw-in, >1 blow-out, 1 = neutral). Values persist in env like any variable — set from [init] (persists forever), [frame] (every frame) or [beat] (on-beat jumps); neutral readings skip the pass entirely (zero cost for every preset that doesn't move).
|
||
2272→ * applyBackground(): snapshot the live canvas into an offscreen buffer (globalCompositeOperation 'copy'), wipe the canvas black (the transformed snapshot must REPLACE the old content, not double-expose), then draw the snapshot back through the frame's transform (translate w/2+bgx*w/2, h/2-bgy*h/2; rotate; scale). Uncovered regions (rotated corners, slid-off edges) read black and the persistence fade blends the trails — exactly how the classic AVS plugins made "speed accelerates to the beat, a hard hit flips the spin, fade stays slow" work: the rate is just a script variable driven by a beatage envelope, and a [beat] section flips a dir variable on hard hits (bass vs bass_att).
|
||
2273→ * Guards: bgNum() falls back to neutral for missing/NaN values (a NaN in a canvas transform matrix would black the screen with no error — every later draw becomes a silent no-op); per-frame clamps rot ±0.6 rad, drift ±0.25, zoom 0.5..2. Buffer recreated automatically on resize; null until first use (zero cost otherwise). Gated on this.script so a stale env after clearScript can never spin a blank canvas.
|
||
2274→- src/lib/ava/embedded-presets.ts — eleventh Zai-Magic preset "osc-rotations" (user-named, lowercase so it sorts last in the tree): persist 0.965 (slow fade — colors blend), [frame] drives bgrot = dir * (0.0032 + punch * (0.014 + vol_att * 0.012)) with punch = exp(-beatage*3.2) (temporary beat acceleration that relaxes with the kick ring), bgzoom = 1 - 0.0009 - punch*0.0011 (a whisper of draw-in so trails spiral inward instead of ringing), hue drifts dt*0.012 + beat*0.02; [beat] flips dir on hard hits only (bass > 1.25 * bass_att — soft beats leave the spin alone); [point] draws the stationary centered scope x = i*2-1, y = v*(0.3+vol_att*0.8) with mirror-symmetric color h = hue + |i-0.5|*2 * 0.34 (points equidistant left/right of center share one hue, the center holds its own). EMBEDDED_SEED_VERSION 7.10 -> 7.12 (route re-seeds the subtree; fingerprint self-heal would have caught it too). "ten presets" comments updated to eleven (both the file-top and the Zai-Magic section header).
|
||
2275→- src/components/ava/help-panel.tsx — bgrot / bgx/bgy / bgzoom rows in the variables table + three example formulas (beat-accelerated spin, hard-hit direction flip in [beat], draw-in).
|
||
2276→- src/lib/version.ts 7.12 + history; src/lib/release-notes.ts 7.12 entry (2x added, first-person voice). Share codec deliberately untouched: its dictionary is a frozen compatibility contract (adding entries needs a new scheme marker) — bg* identifiers ride the pair packing like any custom variable.
|
||
2277→
|
||
2278→HEADLESS VALIDATION (/home/z/tmp-validate/bg-transform/validate-osc.ts, ALL PASS):
|
||
2279→- osc-rotations compiles; all 101 embedded presets still compile (regression guard).
|
||
2280→- Compiled-program behavior: quiet frame bgrot 0.00397 rad/frame cw + bgzoom 0.99906; hard beat bgrot 0.0256 (6.5x) AND dir flips to -1; soft beat no flip; point pass x spans ±1 with |y| symmetric, mirrored positions share hue exactly (0.7906 both) while center is distinct (0.6206).
|

|
||
2282→BROWSER E2E (agent-browser + pixel measurement + VLM, ALL PASS):
|
||
2283→- Fresh boot: title "OVE -- Open Visualization Engine (v7.12)"; tree shows "Zai-Magic -- 11"; /api/presets re-seeded on the version gate and serves osc-rotations (106 presets total; sorts last in Zai-Magic as designed).
|
||
2284→- Preset live on the demo collection (manual load first, then Demo Track — v7.11's respectful-Demo still holds: Random/Sequence stayed UNCHECKED with a preset loaded): footer "SCRIPT: osc-rotations · Demo Track 1/2 · FPS 59-60 · PTS 512 · BPM 132.3/138.8 locked". Mid-band (scope zone) mean 133/255; outer zones lit only by rotation-carried trails.
|
||
2285→- bgrot isolation (line mathematically confined to the middle 35% band, so outer-zone content can ONLY be rotation-carried): outer zones hold a steady mean ~14/255 vs EXACTLY 0.00 in the no-bg control — rotation puts content where the line cannot reach.
|
||
2286→- bgx sign: +0.012 drifts the bright cloud right (mean x 0.518); -0.012 mirrors it exactly (0.480) — the sign convention verified by symmetry.
|
||
2287→- bgy sign: +0.02 pulls the bright cloud UP (mean y-from-top 0.368 vs 0.5 neutral).
|
||
2288→- bgzoom: at 1.05/frame the outer zones went from dead 0.00 to ~38/255 (blow-out pushes the confined line's trails outward); at 1.003/frame with persist 0.92 trails die before traveling far (consistent with the fade math — equilibrium analysis, not a defect).
|
||
2289→- What's New dialog: 7.12 "Background movement (AVS-style) + osc-rotations" first with CURRENT badge, drift guard silent. Help panel: bg* rows + examples all present.
|
||
2290→- VLM on the live screenshot: horizontal oscillating waveform line at vertical center; large soft colorful trail masses around it; hue variation green at the outer left/right edges, yellow mid, red/pink at the center — the mirror-symmetric color design visibly realized; no defects; "60 FPS . 512 PTS" overlay normal.
|
||
2291→- Console clean (0 errors/0 warnings); dev.log clean (59 successful requests, no compile errors). Footer: sticks to the viewport bottom on short pages (1280x800 Beat tab: docH 800, footer bottom 800) and pushes to the document end on long pages (375 px Presets tab: docH 1469, footer at doc end, no overlap); 375 px scrollWidth 375 = clientWidth (no horizontal overflow). Test-browser localStorage cleared afterwards.
|

2292→
|
||
2293→Stage Summary:
|
||
2294→- v7.12 shipped: scripts can move the whole picture — bgrot spins, bgx/bgy slide, bgzoom draws in / blows out — with the speed riding the music exactly the way the classic AVS plugins did it (beatage envelopes drive the rate, [beat] flips the spin on hard hits, persist keeps the fade slow so colors blend). The eleventh Zai-Magic preset "osc-rotations" demonstrates the full recipe: a stationary centered oscilloscope with mirror-symmetric color (left/right shift together, center holds its own hue) over a beat-accelerated, hard-hit-flipping rotating background.

The user supplied the v7.12 build ("updated script editor variables and the osc-rotations preset") as an encrypted zip on Google Drive (password: z.ai) and asked to compare it with this tree's "Upload to OVE-Directory" version (v7.11) and merge the improvements into one build.
|

2300→
|
||
2301→MERGE ARCHAEOLOGY:
|
||
2302→- The Drive zip (openvisengine.zip, 374 MB, AES-encrypted, compression type 99 — Python zipfile can't read it; pyzipper could) extracted to /home/z/drive-712/v712-full: APP_VERSION 7.12, worklog Tasks 37-39 (v7.10.1 spectrum fix, v7.11 wake lock/respectful-Demo/one-click-Save, v7.12 bg movement + osc-rotations). The partial ove-src12/ extraction from the earlier session verified identical (114/115 sha256; the one mismatch was a Drive-fetch artifact named "globals.css CSS").
|
||
2303→- Divergence map via the zip's own .git: BOTH repos share commit d59d398 (tree 953bae5... — IDENTICAL hash on both sides, a true common ancestor at v7.10). After it: this tree shipped v7.11 = the OVE-Directory (directory-tab.tsx, upload-dialog.tsx, /api/ove-directory proxy, lib/ove-directory.ts); the zip tree shipped 7.10.1 + 7.11-wake-lock + 7.12. The ONLY overlapping files were script-tab.tsx, version.ts, release-notes.ts (+ demo-track binaries, identical on both sides).

|
||
2307→- script-tab.tsx (hand-merged): both sides' state blocks kept side by side — ours' uploadOpen/canUpload (Upload to OVE-Directory, gated on ✔ Compiled OK + no runtime error) + theirs' pendingName/rename* states (one-click Save + "Give This Preset a Name"); toolbar now carries the dual Save (target save / one-click new) AND the Upload button; Hash⇢Script import sets pendingName + clears editTarget + markManualChoice; UploadToDirectoryDialog mounted. Verified byte-lossless: diff vs the v7.12 original removes ONLY comment lines (theirs' code 100% intact; ours' upload code added).
|
||
2308→- version.ts + release-notes.ts (hand-merged into ONE timeline): NEW 7.13 entry ("one build, every feature") on top, then 7.12 (bg movement + osc-rotations), 7.11 (the OVE-Directory), 7.10.2 (the parallel line's wake-lock/respectful-Demo/one-click-Save release — RENUMBERED from its original 7.11 so the list reads monotonically; noted in the 7.13 text), 7.10.1 (spectrum edge), 7.10 and below untouched. APP_VERSION = '7.13'. Drift guard green.
|
||
2309→- engine.ts / audio.ts / embedded-presets.ts / wake-lock.ts / help-panel.tsx / audio-source.ts verified BYTE-IDENTICAL to the validated v7.12 originals (cmp) — the parallel line's E2E-proven behavior carries over by construction.

2311→ENVIRONMENT RECOVERY (sandbox quirks, not code):
|
||
2312→- The merge swapped db/custom.db underneath the running server → Prisma "readonly database" (dead inode); fixed by restart.
|
||
2313→- Turbopack's persistent cache panicked twice ("Failed to restore task data — corrupted database") after file replacements/kills; fixed with rm -rf .next + clean start.
|
||
2314→- Directly-spawned background servers were reaped when the Bash session ended; the stable path is the system's own .zscripts/dev.sh (disowned bun run dev). Server now up: / 200, /api/presets 200, /api/ove-directory/* 200.
|
||
2315→- EMBEDDED_SEED_VERSION gate fired on first hit (7.10 -> 7.12): DB re-seeded to 106 presets incl. osc-rotations (verified in SQLite: seed=7.12, count=106, osc-rotations=1).

Zone means: mid-band 69.7/255 (the scope) vs corners 3.3-13.8/255 — outer-zone content can ONLY be rotation-carried (the line is confined to the middle), i.e. applyBackground is rotating the picture in the merged build.

2320→- VLM on the clean capture: (1) bright horizontal oscillating waveform at the vertical center ✓; (2) colorful smeared trail masses at corners/edges "consistent with a rotating background layer smearing trails around the stationary center waveform" ✓; (3) mirror-symmetric hues — yellow/gold at BOTH extremes, warm pink/magenta in the middle ✓; (4) no UI defects ✓.
|

2321→- Script tab: Apply / Save / Script⇢Hash / Hash⇢Script / Upload to OVE-Directory / New / Help ALL present; with a compiling script both Save and Upload enabled (upload title carries the publish/fix-then-apply guidance); Upload dialog opens with the share-string description.
|
||
2322→- One-click Save flow: New (template) -> strip the name header -> Save -> saved as "Empty Name" -> "Give This Preset a Name" dialog opened automatically -> renamed to "Merge Test v713" -> "Preset renamed" toast; test preset removed from localStorage afterwards.
|
||
2323→- Directory tab: live listing via the proxy (1 script, sort controls, "Spectrum Bars · LINES · Average: 4.5 · 2 votes", Get button).
|
||
2324→- Help panel: bgrot / bgx / bgy / bgzoom rows + example formulas all present.
|
||
2325→- What's New dialog: 7.13 "One build, every feature" FIRST with CURRENT badge; 7.12, 7.10.2 in the merged timeline; drift guard silent.
|
||
2326→- Responsive: 375x812 no horizontal overflow (scrollWidth 375 = clientWidth), footer pushed to document end (docH 1651); 1280x800 footer sticks to viewport bottom (800 = 800).
|
||
2327→- Console: 0 errors, 0 warnings (wake lock degrades silently in headless — no navigator.wakeLock); dev.log 0 errors. Test-browser localStorage cleaned afterwards.

|
||
2329→Stage Summary:
|
||
2330→- v7.13 shipped: the parallel line is merged — the spectrum 16 kHz cap, the screen wake lock, the respectful Demo button, the one-click Save with auto-naming + rename dialog, the AVS-style background movement family (bgrot/bgx/bgy/bgzoom) and the eleventh Zai-Magic preset "osc-rotations" all run in the same build as the community OVE-Directory, with one clean version timeline (the parallel wake-lock release folded in as 7.10.2). Only three files needed hand-merging; every engine-side change is byte-identical to its validated original.

2333→Task ID: 41
|
||
2334→Agent: main (Z.ai Code)
|
||
2335→Task: v7.13.1 (user report): in Zai-Magic "Beat Matrix" the rightmost vertical line of dots sat offset +1 upwards -- its bottom dot did not line up with the other columns, and its top dot spilled over onto the next section to the right. Diagnose, explain, fix.
|
||
2336→
|
||
2337→DIAGNOSIS (why the right column was short and a phantom dot spilled):
|
||
2338→- The engine's point position i spans 0..1 INCLUSIVE (classic AVS Superscope convention; engine.ts: i = k/(n-1)). Beat Matrix's grid math assumed exclusive i = k/n: col = floor(i * cols) sends the LAST point (i = 1 exactly) to col 16 -- one column past the 16-column wall (x = 0.986/aspect vs the wall edge 0.87/aspect) at row 0 (top), reading getspec(1.0); and column 15 was left with only 9 dots (rows 0-8, no bottom: its lowest dot sat at y = -0.62 while every other column reaches y = -0.81). Verified headlessly before the fix: col 15 = 9 dots rows 0-8, col 16 = 1 dot, bottom-row y spread col 14 vs 15 = 0.19 script units.
|
||
2339→- Sweep of all other floor(i*M) uses in the library (62 occurrences): every other one is benign -- angular presets close their loop (bar = bars lands exactly on bar 0's angle: seg*tau/segs with seg = segs = 2pi = 0), Aurora Veil's phantom lands off-screen (x = 1.19 > 1), the megabuf particle presets (Bass Bloom, Supernova) draw their phantom slot at alpha 0 (uninitialized megabuf reads 0), Strobe Lattice/Tunnel Vision/Prism Chandelier hide one endpoint dot in rotating/mirrored chaos, and the converted Winamp classics rendered identically under original AVS (which also uses inclusive i) -- their authors saw and accepted exactly this behavior. Beat Matrix was the only hand-authored ALIGNED grid where the defect is obvious, so it was the only one that needed the fix.
|
||
2340→
|
||
2341→Work Log:
|
||
2342→- embedded-presets.ts Beat Matrix [point]: the grid mapping now goes through CELL CENTERS -- cell = i * (cols * rows - 1) + 0.5, col = floor(cell / rows), row = floor(cell - col * rows). Because i = k/(n-1) over n = cols*rows points, cell = k + 0.5 exactly (up to 1-ulp dust), so every floor() sits half a cell away from an integer boundary: the endpoint can never spill and float dust can never shuffle a dot into a neighboring cell. getspec/x/y/hue all read col/row as before (col 0..15, row 0..9; the last point now lands at col 15 row 9, the author's original intent under i = k/n). A 6-line comment in the script documents the why.
|
||
2343→- EMBEDDED_SEED_VERSION 7.12 -> 7.13.1 (library re-seed replaces the DB's Beat Matrix; verified in SQLite: seed = 7.13.1, 106 presets, fixed content present, old mapping gone).
|
||
2344→- version.ts 7.13.1 + history entry; release-notes.ts 7.13.1 "Beat Matrix grid fixed" (fixed, first-person voice).
|
||
2345→
|
||
2346→HEADLESS VALIDATION (/home/z/tmp-validate/beatmatrix/validate.mts, ALL PASS — REAL parser/compiler, not a re-implementation):
|
||
2347→- Regression guard: all 101 embedded presets still compile.
|
||
2348→- The fixed Beat Matrix [point] program executed over all 160 points with the engine's exact i = k/(n-1): 160/160 cells occupied, ZERO duplicates, max col 15, max row 9, bottom-right cell (15,9) present, all 16 columns carry their full 10 rows, 16 distinct x symmetric about 0, 10 distinct y rows aligned.
|
||
2349→
|
||
2350→BROWSER E2E (agent-browser + 8-frame max-brightness composite + VLM, ALL PASS):
|
||
2351→- Fresh load: title "OVE -- Open Visualization Engine (v7.13.1)"; /api/presets re-seeded on the version gate; Beat Matrix loads (PTS 160 = 16x10) and plays on the demo track (FPS 57-60, BPM 133.5 locked).
|
||
2352→- Pixel lattice analysis of an 8-frame composite (captures the treble moments when the high-band columns light): exactly 16 dot columns detected, even 38-39 px gaps; the BOTTOM dot of every one of the 16 columns sits at the SAME pixel row (y = 619, spread 0 px) -- the row-9 position that only exists under the fix (the old code's col-15 lowest dot sat ~80 px higher).
|
||
2353→- Phantom-dot check: the old spill position (x ~722, top row) shows ZERO bright pixels across the composite (x 710-750 all 0); the only brightness right of the wall is column 15's own glow decaying monotonically to nothing by x = 710 (175 -> 45 -> 0 bright-pixel counts), i.e. additive-blend glow, not a dot. The fullscreen-overlay icon (x >= 757) is outside the lattice zone.
|
||
2354→- VLM on the composite: "16 columns"; bottom row fully lit across all 16 columns at the same height (clean straight bottom edge); no stray dot right of the rightmost column; no alignment defects.
|
||
2355→- What's New dialog: 7.13.1 "Beat Matrix grid fixed" first with CURRENT badge; drift guard silent (0 console errors / 0 warnings across the session); dev.log clean (200s only). Test-browser localStorage cleared afterwards.
|
||
2356→
|
||
2357→Stage Summary:
|
||
2358→- v7.13.1 shipped: Beat Matrix's wall is whole -- every column carries its full 10 dots, the bottom edge is straight across all 16 columns, and the phantom dot that spilled past the right edge is gone. The fix lives in the preset's grid math (cell-center mapping, immune to the inclusive-endpoint and float dust alike); the engine's AVS-correct i convention is untouched, and the library re-seed delivers the fixed preset to every visitor.
