Replace the fixed 5-min rotation with end-driven shuffle: each track plays through,
and a short crossfade a few seconds before it ends rolls a random OTHER track
(pickNextIndex, no immediate repeat) — so Music is always playing while selected.
An 'ended' handler is the safety net (short track / missed timeupdate) and a
watchdog resumes an unexpectedly-paused active track. Crossfade injectable via
window.__hefMusicXfadeMs. music-playlist.spec.ts reworked to the end-driven model.

The Music-option tracks are referenced by app.js (MUSIC_PLAYLIST), not the
manifest/ring, so build_static skipped them — Music would 404 on the static

The opening screen only had Volume + Video speed — no way to pick the sound mode
before launching. Add a welcome Audio dropdown (None/Soundtrack/Music) mirroring
the panel; applyWelcomeToPanel carries the choice into the session on launch, None
greys the welcome Volume, and ?audio= presets it on the welcome screen too. +4 e2e
(welcome-audio.spec.ts).

Replace the single ethereal loop with the operator's chosen set — Music for
Manatees, Dewdrop Fantasy, Eastminster, Overheat, Concentration (Kevin MacLeod,
CC BY 4.0, drumless). The Music source now plays one track and every 5 min
crossfades to a random OTHER track (pure HEFScrub.pickNextIndex, never an
immediate repeat), altitude-independent, reusing the two audio elements; both
primed in-gesture for Safari. Intervals injectable via window.__hefMusicRotateMs
/ __hefMusicXfadeMs.
Media loudness-normalized + transcoded under the 25MB LFS limit (build_audio_media
MUSIC), committed via LFS; ethereal loop retired. CC-BY attribution added to
credits.html. Docs updated (music-candidate-pool = final set; audio-candidate-pool
ethereal section superseded).
+2 node unit (pickNextIndex), +2 e2e (music-playlist), audio-source spec updated.
40 unit + 49 e2e green; live probe confirms playback + rotation.

?audio=none|soundtrack|music (and ?vol=0..10) presets the Audio source/volume on
load, so a link opens straight into a chosen sound mode — e.g. share …/?audio=music
with someone who'd prefer music, …/?audio=soundtrack for the ambience. Invalid
values ignored (default Soundtrack stands). +5 e2e (url-params.spec.ts).

Operator kept Dream Culture + Silver Blue Light, rejected the rest (boring or
too much snare). Round-4 = 12 Kevin MacLeod CC-BY tracks, drumless confirmed
from his pieces.json instrument metadata, ranked by chord movement (best:
Impact Lento, Dreams Become Real, Aretes, When The Wind Blows, Reawakening,
Almost New). Lo-fi dropped. review_music.html rebuilt as the drumless cut.

Operator dropped binaural. New direction: mellow, soothing synth with real chord
movement. docs/music-candidate-pool.md = 12 ranked + spares, all CC0 (HoliznaCC0
lo-fi) or CC BY (Kevin MacLeod calming synth), verified live. Local review gallery
simulator/static/review_music.html (gitignored). Binaural doc parked with a pointer.

11 more candidates for the 'not boring' end: MANTICE Sacred Drone series
(bassimat, CC0 — evolving composed ambient, binaural-capable via the generator
but not certified per render), HoliznaCC0 long-form ambient music (FMA, CC0, no
binaural), and shagrugge (ccMixter, CC BY, binaural-filtered vocals). Notes the
CC BY-SA 'Hang Binaural' opt-in (best musical+confirmed-binaural fit, outside the
CC0/CC-BY rule) and the NC drops. review_binaural.html now groups all 22 into
Musical / True-binaural / Ambient sections with honest binaural-status badges.

After the dial sits idle for 60s the altitude drifts one step deeper (descend;
wraps past the deepest back to the top), like a slow kiosk tour. Any manual
interaction (drag/wheel/arrow-key/knob) restarts the idle countdown; a mid-morph
or mid-drag beat is skipped and retried. A default-on 'Auto-advance' toggle in
the Altitude panel disables it. Interval is injectable for tests via
window.__hefAutoAdvanceMs. i18n for 4 langs. +3 e2e (auto-advance.spec.ts).

Widen the panel (280->300px), keep control labels on one line (white-space:

The mood grade was dropped while a morph played (busy): the WebGL canvas set
filter 'none' and the fallback set #vid's filter 'none' on morph load, so the
transition showed ungraded and the grade snapped back only on landing. Now the
grade rides through the morph on both paths (the painterly DREAM stays off mid-
morph, as before, to keep it crisp). +1 e2e (mood-grade.spec.ts).

The Music-option asset produced by build_audio_media.py: deadrobotmusic
'Ambient F Sharp Minor Ethereal Choir Pad' (CC0), sourced from the freesound
hq preview and looped/loudness-normalized to ethereal.loop.mp3 (3:34). Both
the raw source and the served loop are committed via git-LFS, matching the
per-scale soundtracks; served at /media/audio/music/ethereal.loop.mp3.

Split the single 0–10 'Audio' slider into two controls:
- Audio — a dropdown selecting the source: None / Soundtrack / Music
- Volume — the renamed 0–10 slider (master gain for the active source)
Music is one ethereal, relaxing ambient loop played the same at every
altitude (no per-altitude crossfade), per the innerflo.me brief. Sourced
CC0: deadrobotmusic 'Ambient F Sharp Minor Ethereal Choir Pad' (freesound
#808032); added to build_audio_media.py, the candidate-pool doc, and the
public credits colophon. Media stays gitignored; run build_audio_media.py.
Routing lives in a pure, node-tested HEFScrub.audioPlan(source, level, frac);
app.js's restAudio/blendAudio consult it. None greys out Volume. The welcome
screen's mirror level slider is relabeled Volume too. i18n for all 4 langs.
Spec: docs/superpowers/specs/2026-07-01-audio-music-option-design.md
Tests: +5 node unit (audioPlan), +4 e2e (audio-source.spec.ts); 32 related

Add an explicit /human-experience-simulator/ → /human-machine-strata/ 301 (the
subpath splat doesn't match the trailing-slash root).

Build default app-path → /human-machine-strata; deploy.sh APP_PATH default too.
_write_redirects now emits a permanent redirect /human-experience-simulator/* →
/human-machine-strata/:splat so old links still land. Media (R2 bucket) + Pages
project names are unchanged (not in the benstull.art URL). Updated the build
test (asserts the legacy redirect) + static-build e2e path + README paths.

Page <title>, on-page <h1> (app.title — kept as the proper title, same across

membrane the work is about.

On mobile the panel wraps below the (sticky) stage; putting the Altitude knob
first means it sits right under the video instead of behind Output + knobs.

Cloudflare Pages let the /seg/* no-cache rule win over the per-HTML no-store, so
the index was still served no-cache. no-store the whole app path instead — the
shell is tiny and media is on R2 (separate, immutable). Guarantees a fresh index.

With reduce motion on, selecting a new altitude jumps (autoScrub's reduced
branch → setPos) and skips the segment that would re-roll the destination clip,
so activeClipId stayed on the previous altitude's clip and the video didn't
change. Self-heal at the landing point: if the landed altitude's pool doesn't
contain activeClipId, pickPoolClip a fresh one. TDD: new altitude-lock e2e.

Per operator: Think/Feel/Mood group sits above the Altitude knob; remove the
'Turn the knob…' altitude hint (and its dead i18n key); 'Experience knobs (0–4)'
→ 'Experience knobs' (all 4 langs).

no-cache (revalidate) wasn't enough — Safari served a stale cached index from
disk/bfcache, which loaded old versioned JS and broke the page (black, silent).
HTML entry points now no-store (always fresh index → always fresh hashed assets).

Same root cause that retired reverse playback: the resting loop clips aren't
all-intra, so playbackRate >2x makes Safari stutter on inter-frame seeks. Narrow
both sliders (welcome + panel) + the tick datalist to 0–2x; default still 1x.

Per operator: Speed only controls the resting loop, so reduce-motion is still
needed to turn off the morph/transition videos. Re-add a visible 'Reduce motion'
toggle on BOTH the welcome screen and the panel (mirrored, default from OS
prefers-reduced-motion, remembers the choice). When ON, altitude changes are
instant cuts instead of an animated morph tween (autoScrub's reduced branch);
the resting loop is unaffected — it follows the Speed slider (0x freezes it).
Decouples the loop from reduce-motion (was: main froze both videos + disabled
the slider under OS-reduced). playLoop()/landing/applyPlaySpeed no longer check
isReduced(); isReduced() now only gates the morph tween. Welcome controls are
now Language / Speed / Audio / Reduce motion. i18n: restore rm.label (4 langs),
reword warn.body to point at the on-screen control.
Tests: a11y Task 5 reworked (speed independent of reduce-motion; new instant-cut
behavior test); welcome defaults assert reduce-motion off. node 35, e2e 32,
static 2, pytest 301 (3 pre-existing ffmpeg/cv2 env fails).

Real-browser eyeball: below-0x reverse jittered because the base loop
clips aren't all-intra (the flagged risk). Narrow the slider to 0x–4x
forward (still continuous, step=any); 0x still freezes; OS reduced-motion
behavior unchanged. Removes the manual rAF reverse loop and the
HEFScrub.reverseStep helper + its unit tests.
Tests: node unit 10/10; a11y e2e 12/12 (Task 5 now 3 slider tests).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Continuous -2x..2x slider drives ONLY the resting altitude loop video
(#vid-loop); the morph/transition video is scrub-driven and untouched.
Forward = native playbackRate; ~0x = freeze; below 0x = a manual rAF
reverse loop (native negative playbackRate is unreliable). Reverse math
is the pure, node-tested HEFScrub.reverseStep helper.
Reduced-motion accessibility is preserved but now derives live from the
OS prefers-reduced-motion setting (no visible toggle): when active the
loop stays frozen and the slider is disabled. Retires hef.reduceMotion.
i18n: speed.label (en/es/fr/ja); warn.body reworded to point at the OS
setting.
Tests: +4 node unit cases for reverseStep (14/14 green); a11y e2e Task 5
rewritten for the slider (13/13 green); static-build e2e green.

Per docs/superpowers/specs/2026-06-30-welcome-screen-design.md. Fold the bare
#loading splash, the #motion-warning modal, and the #run-sim button into one
#welcome overlay — the universal entry gate:
- State A (.welcoming): heads-up notice + four output controls (Video ON,
Reduce motion OFF, Audio 2, Language) + 'Launch Simulator' button, with the
'Loading Universe' progress pinned at the bottom (media preloads behind it).
- State B (.loading): pressing Launch while still loading hides the messaging +
button, keeps the controls, and centers the loader; entry happens automatically
once phase-1 finishes. Launch when already loaded enters directly.
- The right .panel is hidden until entry (body:has(#welcome)); welcome control
values carry into the panel inputs on entry. Language + Reduce motion drive the
shared state live (both selects/checkboxes mirror); Video + Audio apply on entry.
- Launch is the single audio-unlock gesture (beginExperience runs in-gesture even
when entry is deferred). Retire WARN_KEY (welcome shows every load); entry uses
the chosen Audio level rather than forcing 2.
- i18n: new welcome.launch key + es/fr/ja for the heads-up (warn.title/body),
reworded to point at the on-screen Reduce-motion control; drop dead run.button.
Tests: new welcome.spec.ts (defaults, live language re-render, State B
deferred-entry, straight-in when loaded, control carry-over, panel hidden);
update altitude-lock/a11y/i18n/loop-recovery/static-build e2e + the Python
audio/credits e2e to the welcome flow; add a window.__hefReady diagnostic seam.

A drag is a way of grabbing the altitude dial, not a free-standing encoder
detent. Until now onDialUp held the live blend wherever the knob stopped (the
"no auto-complete" model), so a grab-and-release could leave the experience
parked mid-morph between two altitudes.
Now a real turn (moved >= 6) auto-scrubs the short way to Math.round(pos) and
settles there (frac 0 locks) — a grab-and-release always lands on a discrete
altitude, exactly like a tap or label click. The tap path (moved < 6 ->
jumpToScale) is unchanged, and reduced motion is handled by autoScrub (jump to
target, no tween).
Adds an altitude-lock e2e asserting a partial drag settles on an integer
altitude after release. Full altitude-lock (14) + a11y + i18n suites green.

Unify #loading / #motion-warning / #run-sim into one #welcome overlay:

entry gesture. Forward note: extra welcome copy lands later.
