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).

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.

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).

Clamp each per-altitude step to the WCAG 2.3.1 floor (no-op at 1200ms, guards

Affect was authored per SCALE — every clip in an altitude shared the same 4
emotion words. Now every clip carries its OWN feelings, read from that specific
footage (mood, motion, light), so e.g. the violent Tarantula nebula evokes "a
violent ferment" while the dying-star Southern Ring evokes "a star's slow dying /
a luminous farewell," and a drowsing seal haul-out evokes "a sun-warmed drowse."
Adds AFFECT_CLIP (per-clip override; falls back to the scale register) covering
all 41 clips — 41 distinct feeling-sets, one per clip. Keeps each scale's
emotional family as a base and swaps in 1-2 footage-specific feelings, reusing the
existing feel.* palette where it fits and adding 19 new nuance keys (sublime,
tenderness, turbulence, radiance, mortality, poignancy, eeriness, purity,
solitude, verdancy, freshness, repose, hush, poise, flow, intricacy, spectral,
alienness, strangeness) with full es/fr/ja. 42 distinct feeling keys now in use.
Drafted by viewing each clip's footage (per-scale passes); first-pass reads that
want operator by-eye review. Data-only (build_pool_manifest.py + manifest + i18n
catalogs). Verified: 34/34 catalog+i18n+build pytest, 16/16 node unit, 4-language
parity for every clip, live render shows distinct feelings per clip (incl. new
keys) with Think/Feel overlap still 0.

The hold-last-frame settle gated playLoop() behind a canplay event that doesn't
re-fire on an already-loaded element → the next altitude's video never started.
Reverted to the simple swap, and gate the universe on a full preload (every base +
every morph) so navigation is smooth with no on-demand stall. Adds a ?debug on-screen
media-state overlay for diagnosing real-browser playback.

s0031 removed "About this work" to avoid duplicating it on the separate About
page, but that section WAS the D1 compliance — it declares the altered work is a
derivative offered under CC BY-SA 4.0, which is what satisfies the ShareAlike
obligation for the BY-SA source clips. Without it the live site credited the
BY-SA authors but never declared the derivative share-alike.
Restore the declaration on the credits page, under the heading "License & reuse"
instead of "About this work" so it isn't confused with the separate About page
(which covers the project's intent). Tests assert the declaration is present and
that the heading is NOT "About this work".

The CC BY-SA work-license declaration ("About this work") was on the credits
page, but the About page (built on the parallel feat/accessibility-pass) will
own that content; keeping it in both places would duplicate it. Remove the
section from credits.html and make the footage note self-contained (it still
states the footage is altered — the per-clip "indicate modifications" cue stays
with the attributions). Tests updated to assert the declaration is intentionally
no longer on the credits page. The .declaration CSS rule is left in place for the
About page to reuse.

Denser left labels (now >=3/clip) plus the always-4 right affect words made the
two HUD layers collide. renderAffect now nudges each Feel word vertically off the
Think chip plates (and off already-placed words + the ANALYSIS status tag),
staying on-screen, keeping the least-overlapping spot if nothing is fully clear.
Feelings are scene-level (soft position) so we move THEM, never a chip off its
subject. Obstacles are computed from the manifest, not the DOM, and a tracked
label's path is sampled across the loop — so the clearance holds for the whole
loop even though the per-frame track re-render keeps moving the chips (no per-frame
re-layout, no jitter). New diagnostic seam window.__hefNoDeconflict (sibling of
__hefState) A/B-toggles it.
Verified across all 6 scales at max knobs: authored overlaps drop to 0 with none
introduced (cosmos 3->0), and a tracked abyss clip stays at 0 overlaps sampled
over loop time as its chip drifts. No affect-position test exists to break;
16/16 node unit + frontend pytest green.

Boot becomes ready on the first clip and streams the rest in the background
(was: blocked on the full ~2.3 GB before 'Run simulation' appeared). During nav,
the visible morph and landing base only swap to cached blobs — otherwise the
current frame holds (settleGen guards a stale settle) — so rapid altitude-clicking
never blanks the stage.

CC BY / CC BY-SA footage needs its author + license shown to the viewer, and the
installation alters every frame (a derivative). Per-clip license/source already
shipped in clips.json but only surfaced in the dev panel and internal review
pages — the public experience showed nothing, so the static benstull.art site
was not attribution-compliant.
Option A — add a manifest-driven credits/colophon (credits.html + credits.js):
the page fetches the same clips the experience uses (baked clips.json in static,
the live API otherwise) and renders one attribution block per clip (title,
license, source), HTML-escaped, sorted, never silently dropping a clip. An
"ⓘ Credits & licenses" link in the header (localised en/es/fr/ja) makes it
reachable from the work — what CC's "reasonable to the medium" calls for. Audio
is all PD/CC0, credited as a courtesy block.
Option D1 — the colophon declares the altered work itself is offered under
CC BY-SA 4.0 and states the footage is modified, satisfying the ShareAlike +
"indicate changes" obligations for the BY-SA sources. Non-commercial.
Ships in the static build (added to PUBLIC_ASSETS). Verified: 41/41 clips
credited incl. all 7 CC-BY/BY-SA clips, 0 missing a license. Tests: node units
for creditEntries/creditsListHtml + escaping + page structure/declaration;
pytest build-output assertion; Playwright e2e (page lists attributions, header
links through).

Every clip now carries at least 3 factual LEFT annotations to match the 4 RIGHT
(Feel) affect words — fixes the "many clips missing Think labels" asymmetry
(right read "everywhere", left felt sparse). Adds one researched factual label to
each of the 23 thin clips (orbit_bluemarble had only 1; 22 had 2), with full
es/fr/ja parity via the catalogs, and converts the 4 still-static abyss creature
subjects (octopus, bigfin squid, dandelion siphonophore, sea pig) from fixed
boxes to 3-keyframe motion-tracked labels (tracked clips 7 -> 11).
Boxes/tracks are a first pass sampled by eye from base footage (t=0.05/0.5/0.95);
they want operator by-eye review in author mode to fine-tune positions. Remaining
static clips are landscapes (correctly static) plus 2 diffuse fish schools and 2
surface-animal scenes, available for author-mode tracking if wanted.
Data-only change (build_pool_manifest.py LABELS + manifest + i18n catalogs); no
app/engine code touched. Verified: 43/43 manifest+catalog+i18n pytest, 16/16 node
unit, live render shows 3 chips/clip in all 4 languages with no JS errors. (The 3
failing pytest are pre-existing cv2/ffmpeg-absent env limits, unrelated.)
Note: the reported "audio not playing" was a false alarm — exhaustive repro
(Chromium+WebKit, strict autoplay, both servers, RMS-verified non-silent files)
found the audio engine correct; the operator's Safari output was muted.

The experience boots silent and waits for a gesture (browser autoplay blocks
an un-gestured audio play()). Until now that gesture was an unlabelled Video
toggle — not obvious to a first-time viewer. Add a "Run simulation" button,
revealed over the black stage once media has preloaded; clicking it turns
Video on, snaps the audio dial to a gentle 2/10, dismisses the prompt, and
starts the soundtrack in that one gesture. Turning Video on directly still
begins the experience too (couples audio in, dismisses the button) via a
shared beginExperience(). Localised en/es/fr/ja.
E2E coverage updated (Playwright + pytest-playwright): button shown after
load, button starts video+audio+dismisses, and direct-Video-on path.

Ascending the altitude dial and landing on the higher-altitude clip jumped ~3
seconds. A baked morph `transitions/{h}__{l}.mp4` spans src@0 (frac 0) ->
dst@~LOOP_TAIL_S (frac 1) and is scrubbed bidirectionally, but the steady loop
element always seeked LOOP_TAIL_S (3.0s) on landing. Descending lands on dst at
its tail (matches the seek — the s0026 loop-from-tail fix); ascending lands on
src at the morph's HEAD (src@0), so seeking the tail was a 3s jump.
Make the loop landing frame direction-aware: pure `HEFScrub.loopLandFrame(dir,
loopTailS)` returns 0 when ascending, loopTailS otherwise. `loadLoop` takes a
`landFrame`, stores it as `dataset.loopStart`, and the timeupdate/ended wrap
handlers honor it (the base clips are already seamless crossfade-loops, so a
reverse landing wraps [0,dur] cleanly). The settle path lands explicitly on the
direction's frame so a fast ascent never jumps even if the heading clip wasn't
preloaded in time. App-side only — no 154-morph LFS re-bake.
Verify: node unit (loopLandFrame) + a new reverse-landing e2e asserting the loop
anchors at the head (loopStart "0"), and the existing forward "loops from tail"
e2e still green (12/12 altitude-lock).

Every rotating-pool clip shipped with right-brain `affect` (auto-generated per
scale by _affect_for_clip) but only 13 carried LEFT-brain factual `LABELS`. The
other 28 rendered with no detected.*/measure.* labels at any Left knob level.
Authors static tiered labels (general → specific → scientific → +fact) for all
28 — 5 cosmos, 4 orbit, 8 sky, 5 coast, 2 reef, 4 abyss — in build_pool_manifest.py
following the existing static_label pattern, plus their es/fr/ja translations in
tools/i18n/catalogs (binomials/measurements kept verbatim; units localized per
each catalog's convention). Rebuilds the manifest and merges all four languages.
Result: 41/41 clips now have left+right annotations with full en/es/fr/ja parity.
Labels are static (footage not eyeballed); the abyss/reef creature clips could
later be upgraded to tracked labels via author mode.

The post-load autoStart() flipped Video on and lifted audio to 3/10 with no
user gesture. Browser autoplay policy blocks an audio play() made outside a
gesture (muted video survives, sound does not), so auto-start showed video but
stayed silent. Boot SILENT instead and wait for the operator to turn Video on —
that click IS the gesture, and its handler couples audio to 3/10 and starts the
soundtrack in-gesture, so sound reliably comes up with video.
Updates the pytest e2e + Playwright e2e specs to assert boot-silent + the
video-on-couples-audio wiring instead of the old auto-start wiring.

Root cause: the steady-state loop (#vid-loop) restarts only via a narrow
timeupdate window (last 0.08s -> seek to LOOP_TAIL_S), with native loop off.
Headless Chromium reliably lands a final timeupdate in that window, but under
real-browser decode/GPU load a timeupdate can skip past it; the clip then fires
'ended' and freezes on its last frame ('videos aren't looping'). There was no
recovery path. Add an 'ended' listener that seeks back to the tail and resumes,
guaranteeing the loop regardless of the timeupdate race. No change to normal
playback. Proven by a Playwright regression test that forces the ended state.

Expanded-pools sky-scale work plus two experience tweaks:
- New `sky` altitude (airplane-window / low-flight layer) between orbit and
coast; RING_ORDER cosmos·orbit·sky·coast·reef·abyss. New clip pools across
all scales, re-baked the full adjacent-pair morph set (all-intra, LFS), and
removed the now-stale cosmos↔abyss transitions the old ring order produced.
- Auto-start: once the preload finishes the experience turns Video on and
raises the audio dial to 3/10 with no user gesture (app.js autoStart()).
- Dropped reef_hawaiian (text overlay — violates the text-free pool rule);
reef pool 7→6, manifest transitions 586→558.
Tests: rewrote tests/test_e2e_audio.py for the dial UI + auto-start; updated

Operator: slow click/auto transitions 2x and make them the same speed between any two
altitudes (2 away should take twice as long as 1). autoScrub duration is now
PROPORTIONAL to distance (PER_ALTITUDE_MS=1200, ~2x the old fixed 600ms total): a
label-click or wheel jump of N altitudes takes N*1200ms, so per-step speed is constant.
Manual drag is unaffected (operator drives its speed). E2E asserts a 2-step jump is
~2x a 1-step.

Operator: audio turned off sometimes after landing on a new altitude. Root cause:
fadeVolume started a setInterval ramp that was never cancelled. When restAudio faded
the idle element to 0 and — within FADE_MS — that same element became the newly-landed
ACTIVE scale (assignElements reuses an element per soundtrack url), the stale fade-to-0
kept running and dragged the now-active element back to silence. Fix: cancelFade()
supersedes any in-flight fade when a new fade starts (fadeVolume) or a direct volume
is set (ensurePlaying). E2E proves a new fade supersedes a stale one (fails without
the fix).

Operator request. Replaces the Audio checkbox with a 0-10 range slider that sets the
master soundtrack gain (audioVol = level/10), scaling both the per-scale rest volume
and the two-track scrub crossfade. Level 0 = silent. Turning Video on for the first
time now raises audio to 3/10 (was: full on) so the experience opens gently; raising
the slider from 0 unlocks playback in-gesture (Safari). E2E: dial is range 0-10
default 0, and first video-on lifts it to 3/10.

Operator eyeball: a jolt/pause when the morph ends and the next altitude's loop
loads. Root cause: swapping vid.src to the base + seeking to the tail reloaded the
ON-SCREEN element (decode + seek stall). Now a dedicated #vid-loop element carries
the steady-state base loop; during a scrub it is PRELOADED to the clip we're heading
toward, seeked to the tail and paused on that exact frame. The paint shader reads the
active source (busy ? morph : loop), so landing is an instant source swap — no reload,
no seek. E2E asserts the loop element is armed + playing from ~3s after landing.
