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:
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.

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.

Pages caches .js/.css by type (max-age=14400) and ignores _headers for them, so
returning visitors ran stale JS (no-video/no-audio until a private window). index.html
is no-cache and now references app.js?v=<hash> etc., so a normal reload always gets
fresh code; media on R2 stays immutable.

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".

Adds the Reduce-motion toggle markup + i18n label in the same Output
fieldset (wired in a later task). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.

The audio layer built the soundtrack url as a literal /media/audio/<f>, which 404s
on the static R2 build (audio err 4, silent). Route it through mediaBase() like the
video path: dev → /media/ (unchanged), static → https://static.benstull.art/. Verified
live: aud loads 200 from R2 and plays.

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.
