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
e2e green, 38 node unit green.

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
all 4 languages), the About + Credits headings/prose, and the author dev tool.
"Strata" = the layered cosmos→abyss descent; the slash = the human↔machine
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).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.

These were accidentally committed (tracked on main); they are regenerated on

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.

Continuous -2x..2x speed control for the resting altitude loop video

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:
heads-up notice + four output controls (Video on, Reduce motion off,
Audio 2, English) + Loading Universe progress. Two states (welcome →
centered loading); right panel hidden until entry; Continue is the single
entry gesture. Forward note: extra welcome copy lands later.

The PreToolUse guard blocked ALL edits while in the main checkout — including files
outside the repo (auto-memory, /tmp, scratchpad). Now it only denies edits to files
under the main checkout's working tree; external files are allowed.

Multiple sessions sharing this one checkout clobbered each other (branch switches,
edits landing on the wrong branch). Enforce per-session isolation:
- worktree.bgIsolation=worktree + baseRef=fresh (native bg-session isolation)
- PreToolUse(Edit|Write|NotebookEdit) hook DENIES edits while in the main checkout
- SessionStart hook directs each session to EnterWorktree (fresh worktree, off main)
.claude/hooks/worktree-guard.sh detects main-vs-worktree via git-dir != git-common-dir.

Gate the universe on one clip per altitude + connecting morphs (~126 MB, ~10-20s),
then grow the pool in the background. The random pick (pickPoolClip/pickRandomMember)
is restricted to fully-loaded clips — base + connecting morphs both ways cached
(HEFPreload.eligibleDestinations) — so a transition never stalls on un-downloaded
media and new clips become reachable only once fully loaded. Pure planner in
preload.js (+ node tests).

Integrates the fully-static Cloudflare publish line (live at
benstull.art/human-experience-simulator) into main: the static build (Pages + R2,
manifest-only media tree, baked API JSON), the "Run simulation" start button, the
public CC-BY/BY-SA credits page with the "License & reuse" CC BY-SA 4.0 derivative
declaration (Option A + D1), the repeatable Cloudflare deploy script, and assorted
load/audio fixes (progressive boot, scaleAudioUrl via mediaBase).
Clean auto-merge with main's per-clip affect/feelings + i18n work — only app.js and
altitude-lock.spec.ts overlapped, both auto-resolved. Verified green on the merged
tree: node 29, pytest 315 passed / 2 skipped.

Clamp each per-altitude step to the WCAG 2.3.1 floor (no-op at 1200ms, guards
a future lowering). Audit: #black fade + audio crossfade can't exceed 3/sec, no
clamp needed. boot() now seeds the gate-dismissed flag (returning visitor) so
the run-sim test isn't blocked by the new interstitial.
