feat(load): phase-1 preload gate + eligible-pick pool growth

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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+# Accessibility Pass + About Page Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make the simulator usable away from the attended kiosk — reduced-motion, seizure safety, keyboard/screen-reader access, AA contrast — and add an English-first `about.html`.
+
+**Architecture:** All client-side in `simulator/static/`. One new pure helper (`flash.js`, UMD + node tests). One new page (`about.html`) mirroring `credits.html`. Behavior changes live in `app.js`; chrome/contrast in `style.css` and `index.html`. The Python static build (`tools/build_static.py`) copies the new static files.
+
+**Tech Stack:** Vanilla JS (no framework, UMD modules like `i18n.js`/`credits.js`), CSS, Playwright e2e (`simulator/e2e/`), `node --test` for pure helpers, FastAPI dev server for e2e fixtures.
+
+## Global Constraints
+
+- No engine/Python behavior changes — only `tools/build_static.py`'s copy list is touched.
+- New JS modules follow the existing **UMD** pattern (browser global + `module.exports`), like `i18n.js` and `credits.js`.
+- About page is **English-first**; i18n keys may be EN-only and fall back via `pickUiString` (returns `v.en`).
+- Target **WCAG 2.1 AA** (4.5:1 text / 3:1 large) plus WCAG 2.3.1 (≤3 flashes/sec) and 2.3.3 (no autonomous animation under reduced-motion).
+- Persist user toggles in `localStorage`, mirroring `DEV_KEY = "hef.devMode"` (`app.js:918`).
+- Reduced-motion toggle key: `RM_KEY = "hef.reduceMotion"`. Warning-gate dismissal key: `WARN_KEY = "hef.motionWarnDismissed"`.
+- `<html lang>` switching already exists (`applyUiStrings`, `app.js:1325`) — do NOT re-implement.
+- E2E in this env: start uvicorn by hand with the venv `python` (only `python3` exists on PATH) and run Playwright with `reuseExistingServer`. `loop-recovery.spec.ts` is known-red on a clean baseline (boots without video).
+- Direction convention: descend = `+1` (cosmos→abyss), matching wheel-down (`app.js:703`).
+
+---
+
+### Task 1: Output-panel layout — language picker below Audio, globe inline-left
+
+**Files:**
+- Modify: `simulator/static/index.html:37-51` (Output fieldset)
+- Modify: `simulator/static/style.css` (add `.lang-pick` rule)
+- Test: `simulator/e2e/tests/a11y.spec.ts` (new)
+
+**Interfaces:**
+- Produces: the `#lang-select` element ends up after `#audio` in DOM order; `.lang-pick` is a flex row.
+
+- [ ] **Step 1: Write the failing e2e test**
+
+Create `simulator/e2e/tests/a11y.spec.ts`:
+
+```ts
+import { test, expect } from "@playwright/test";
+
+test("language picker sits below the Audio control", async ({ page }) => {
+  await page.goto("/");
+  const audio = page.locator("#audio");
+  const lang = page.locator("#lang-select");
+  await expect(audio).toBeVisible();
+  await expect(lang).toBeVisible();
+  const aBox = await audio.boundingBox();
+  const lBox = await lang.boundingBox();
+  expect(lBox!.y).toBeGreaterThan(aBox!.y); // lang is rendered lower than audio
+});
+
+test("globe icon is inline-left of the language select (same row)", async ({ page }) => {
+  await page.goto("/");
+  const pick = page.locator(".lang-pick");
+  const select = page.locator("#lang-select");
+  const pBox = await pick.boundingBox();
+  const sBox = await select.boundingBox();
+  // select starts to the right of the label's left edge, and shares its row (height ~ one line)
+  expect(sBox!.x).toBeGreaterThan(pBox!.x);
+  expect(pBox!.height).toBeLessThan(40);
+});
+```
+
+- [ ] **Step 2: Run it to verify the first test fails**
+
+Start the dev server (separate shell, from `simulator/`):
+`../.venv/bin/python -m uvicorn server.app:app --port 8000` (adjust to the project's venv/module path).
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "below the Audio"`
+Expected: FAIL (lang currently renders above audio).
+
+- [ ] **Step 3: Move the language picker in `index.html`**
+
+In the Output `<fieldset>`, delete the `<label class="lang-pick">…</label>` block from its current spot (above the Video toggle) and re-insert it as the LAST child of the fieldset, after the Audio `<label class="audio-level">`. Result order: legend → Video toggle → Audio level → language picker.
+
+- [ ] **Step 4: Add the `.lang-pick` flex rule in `style.css`**
+
+Add near the other panel rules:
+
+```css
+/* Globe + language select on one row (the select no longer goes full-width here). */
+.lang-pick { display: flex; align-items: center; gap: 0.4rem; margin: 0.4rem 0; }
+.lang-pick select { flex: 1; width: auto; }
+```
+
+- [ ] **Step 5: Run both layout tests to verify pass**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "language picker|globe"`
+Expected: PASS (2 tests).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add simulator/static/index.html simulator/static/style.css simulator/e2e/tests/a11y.spec.ts
+git commit -m "feat(a11y): move language picker below Audio, globe inline-left"
+```
+

+
+### Task 2: Low-vision contrast + global focus rings + visually-hidden utility
+
+**Files:**
+- Modify: `simulator/static/style.css` (color bumps, `:focus-visible`, `.visually-hidden`)
+
+**Interfaces:**
+- Produces: a `.visually-hidden` utility class used by Task 4 (gate) and Task 7 (aria-live).
+
+- [ ] **Step 1: Bump failing text colors to AA**
+
+In `style.css`, change these declarations (values chosen to clear 4.5:1 on the dark backgrounds; verify with a contrast check in Step 3):
+
+```css
+/* was #789 — too low on #111 */
+.hint { color: #9fb3c8; }
+/* dial labels/captions were #789ac0 / #4d6184 on #0d1320 */
+.dial-label { fill: #b8cfe6; }
+.dial-caption { fill: #8fa6c4; }
+```
+
+(Keep every other property on those selectors unchanged — edit only the color/fill.)
+
+- [ ] **Step 2: Add focus-visible + visually-hidden utilities**
+
+```css
+/* Visible keyboard focus for every interactive element (was only on .dev-switch). */
+:focus-visible { outline: 2px solid #9af; outline-offset: 2px; }
+#dial:focus-visible { outline-offset: 4px; }
+/* Screen-reader-only text (announcements, labels) — present in a11y tree, off-screen. */
+.visually-hidden {
+  position: absolute; width: 1px; height: 1px; margin: -1px; padding: 0;
+  overflow: hidden; clip: rect(0 0 0 0); white-space: nowrap; border: 0;
+}
+```
+
+- [ ] **Step 3: Verify contrast**
+
+Manually confirm with any WCAG contrast tool that `#9fb3c8` on `#111`, `#b8cfe6` on `#0d1320`, and `#8fa6c4` on `#0d1320` each meet ≥4.5:1 (≥3:1 acceptable for the dial caption if it reads as large). Adjust lighter if any fails.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add simulator/static/style.css
+git commit -m "feat(a11y): AA contrast bumps, global focus-visible, visually-hidden util"
+```

+
+### Task 3: `flash.js` — pure flash-clamp helper + node tests
+
+**Files:**
+- Create: `simulator/static/flash.js`
+- Test: `simulator/static/flash.test.js` (new, `node --test`)
+
+**Interfaces:**
+- Produces: `HEFFlash.minSafeDurationMs(count)` → minimum total ms for `count` luminance transitions to stay ≤3/sec; `HEFFlash.clampDurationMs(requestedMs, count)` → `max(requestedMs, minSafeDurationMs(count))`. Consumed by Task 8 (audit).
+
+- [ ] **Step 1: Write the failing test**
+
+Create `simulator/static/flash.test.js`:
+
+```js
+const test = require("node:test");
+const assert = require("node:assert");
+const F = require("./flash.js");
+
+test("minSafeDurationMs: N transitions need N/3 seconds", () => {
+  assert.strictEqual(F.minSafeDurationMs(3), 1000); // 3 flashes in >=1s
+  assert.strictEqual(F.minSafeDurationMs(6), 2000);
+  assert.strictEqual(F.minSafeDurationMs(0), 0);
+  assert.strictEqual(F.minSafeDurationMs(1), 1000 / 3);
+});
+
+test("clampDurationMs: stretches only when too fast", () => {
+  assert.strictEqual(F.clampDurationMs(2000, 3), 2000); // already safe
+  assert.strictEqual(F.clampDurationMs(200, 3), 1000);  // too fast → clamped up
+  assert.strictEqual(F.clampDurationMs(500, 1), 500);   // single transition, slow enough
+});
+```
+
+- [ ] **Step 2: Run it to verify it fails**
+
+Run: `cd simulator/static && node --test flash.test.js`
+Expected: FAIL ("Cannot find module './flash.js'").
+
+- [ ] **Step 3: Implement `flash.js`**
+
+```js
+// Pure photosensitivity helper. WCAG 2.3.1: no more than 3 general flashes
+// (luminance transitions) per second. Given a transition COUNT, returns the
+// minimum total duration that keeps the rate at or below 3/sec, and a clamp
+// that only ever slows a transition down. UMD: browser `HEFFlash` + require().
+(function (root, factory) {
+  const api = factory();
+  if (typeof module !== "undefined" && module.exports) module.exports = api;
+  else root.HEFFlash = api;
+})(typeof self !== "undefined" ? self : this, function () {
+  "use strict";
+  const MAX_PER_SEC = 3;
+  function minSafeDurationMs(count) {
+    const n = Math.max(0, Number(count) || 0);
+    return (n / MAX_PER_SEC) * 1000;
+  }
+  function clampDurationMs(requestedMs, count) {
+    return Math.max(Number(requestedMs) || 0, minSafeDurationMs(count));
+  }
+  return { MAX_PER_SEC, minSafeDurationMs, clampDurationMs };
+});
+```
+
+- [ ] **Step 4: Run tests to verify pass**
+
+Run: `cd simulator/static && node --test flash.test.js`
+Expected: PASS (2 tests).
+
+- [ ] **Step 5: Commit**
+
+```bash

+
+### Task 4: Photosensitivity warning gate
+
+**Files:**
+- Modify: `simulator/static/index.html` (gate markup inside `.screen`)
+- Modify: `simulator/static/style.css` (gate styles)
+- Modify: `simulator/static/app.js` (gate logic around `run-sim` reveal, `app.js:1297`)
+- Modify: `simulator/static/i18n.js` (gate strings)
+- Test: `simulator/e2e/tests/a11y.spec.ts`
+
+**Interfaces:**
+- Consumes: nothing.
+- Produces: `WARN_KEY` localStorage flag; `maybeShowMotionWarning()` called before `run-sim` is revealed.
+
+- [ ] **Step 1: Write the failing e2e test**
+
+Append to `a11y.spec.ts`:
+
+```ts
+test("motion warning gate shows once, then is remembered", async ({ page }) => {
+  await page.goto("/");
+  const gate = page.locator("#motion-warning");
+  await expect(gate).toBeVisible();
+  await page.locator("#motion-warning-continue").click();
+  await expect(gate).toBeHidden();
+  // Reload: dismissal persisted, gate stays hidden, run-sim is the entry point.
+  await page.reload();
+  await expect(page.locator("#motion-warning")).toBeHidden();
+  await expect(page.locator("#run-sim")).toBeVisible();
+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "motion warning"`
+Expected: FAIL (no `#motion-warning`).
+
+- [ ] **Step 3: Add gate markup in `index.html`**
+
+Inside `<div class="screen">`, after the `#run-sim` button:
+
+```html
+<div id="motion-warning" class="motion-warning hidden" role="dialog" aria-modal="true" aria-labelledby="mw-title">
+  <div class="mw-card">
+    <h2 id="mw-title" data-i18n="warn.title">Heads up — motion &amp; flashing</h2>
+    <p data-i18n="warn.body">This experience contains continuous motion, flashing, and shifting imagery. If you are sensitive to motion or flashing light, turn on “Reduce motion” in the panel before you begin.</p>
+    <button type="button" id="motion-warning-continue" class="run-sim" data-i18n="warn.continue">Continue</button>
+  </div>
+</div>
+```
+
+- [ ] **Step 4: Add gate styles in `style.css`**
+
+```css
+.motion-warning { position: absolute; inset: 0; z-index: 70; display: flex;
+  align-items: center; justify-content: center; padding: 1rem;
+  background: rgba(2, 4, 10, 0.92); }
+.motion-warning.hidden { display: none; }
+.mw-card { max-width: 30rem; text-align: center; color: #dfeaff; }
+.mw-card h2 { font-size: 1.1rem; margin: 0 0 0.6rem; }
+.mw-card p { font-size: 0.95rem; line-height: 1.5; margin: 0 0 1.2rem; color: #b9c8e0; }
+.mw-card .run-sim { position: static; transform: none; }
+.mw-card .run-sim:hover { transform: scale(1.04); }
+```
+
+- [ ] **Step 5: Add i18n strings in `i18n.js`**
+
+Add to `UI_STRINGS` (EN required; other langs may be added later, fallback is EN):
+
+```js
+"warn.title":    { en: "Heads up — motion & flashing" },
+"warn.body":     { en: "This experience contains continuous motion, flashing, and shifting imagery. If you are sensitive to motion or flashing light, turn on “Reduce motion” in the panel before you begin." },
+"warn.continue": { en: "Continue" },
+```
+
+- [ ] **Step 6: Wire gate logic in `app.js`**
+
+Add near `DEV_KEY` (`app.js:918`):
+
+```js
+const WARN_KEY = "hef.motionWarnDismissed";
+function motionWarnDismissed() {
+  try { return localStorage.getItem(WARN_KEY) === "1"; } catch (_) { return false; }
+}
+function maybeShowMotionWarning() {
+  const gate = $("motion-warning");
+  if (!gate) return;
+  if (motionWarnDismissed()) { gate.classList.add("hidden"); return; }
+  gate.classList.remove("hidden");
+  $("motion-warning-continue").addEventListener("click", () => {
+    try { localStorage.setItem(WARN_KEY, "1"); } catch (_) {}
+    gate.classList.add("hidden");
+    $("motion-warning-continue").focus({ preventScroll: true });
+    $("run-sim").focus({ preventScroll: true });
+  }, { once: true });
+}
+```
+
+In `main()`, immediately after `$("run-sim").classList.remove("hidden");` (`app.js:1297`), add:
+
+```js
+  maybeShowMotionWarning();    // photosensitivity notice on first visit (over the stage)
+```
+
+- [ ] **Step 7: Run the gate test to verify pass**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "motion warning"`
+Expected: PASS. (If `localStorage` carries across tests, the test clears it via `page.goto` fresh context — Playwright uses a fresh context per test by default.)
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add simulator/static/index.html simulator/static/style.css simulator/static/app.js simulator/static/i18n.js simulator/e2e/tests/a11y.spec.ts

+
+### Task 5: Reduced-motion freeze-to-stills + toggle
+
+**Files:**
+- Modify: `simulator/static/index.html` (toggle in Output fieldset)
+- Modify: `simulator/static/i18n.js` (toggle label)
+- Modify: `simulator/static/app.js` (`reduceMotion` state, freeze logic, `autoScrub` instant path)
+- Test: `simulator/e2e/tests/a11y.spec.ts`
+
+**Interfaces:**
+- Consumes: nothing.
+- Produces: `reduceMotion` boolean; `isReduced()` accessor used by `autoScrub` (Task 5) and dial keyboard (Task 6); `applyReduceMotion()` pauses/resumes playback.
+
+- [ ] **Step 1: Write the failing e2e test**
+
+Append to `a11y.spec.ts`:
+
+```ts
+test("reduce-motion toggle pauses video playback", async ({ page }) => {
+  await page.goto("/");
+  // Dismiss the gate and start the experience so video is playing.
+  await page.locator("#motion-warning-continue").click().catch(() => {});
+  await page.locator("#run-sim").click();
+  await page.waitForTimeout(400);
+  await expect.poll(() => page.locator("#vid-loop").evaluate((v: HTMLVideoElement) => v.paused)).toBe(false);
+  await page.locator("#reduce-motion").check();
+  await expect.poll(() => page.locator("#vid-loop").evaluate((v: HTMLVideoElement) => v.paused)).toBe(true);
+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "reduce-motion toggle"`
+Expected: FAIL (no `#reduce-motion`).
+
+- [ ] **Step 3: Add the toggle markup in `index.html`**
+
+In the Output fieldset, after the Audio level label (and before the language picker added in Task 1), add a switch mirroring the existing `.dev-switch`:
+
+```html
+<label class="dev-switch" for="reduce-motion">
+  <input type="checkbox" id="reduce-motion" />
+  <span class="dev-switch-track"><span class="dev-switch-thumb"></span></span>
+  <span class="dev-switch-label" data-i18n="rm.label">Reduce motion</span>
+</label>
+```
+
+- [ ] **Step 4: Add the i18n label in `i18n.js`**
+
+```js
+"rm.label": { en: "Reduce motion", es: "Reducir movimiento", fr: "Réduire les animations", ja: "動きを減らす" },
+```
+
+- [ ] **Step 5: Add `reduceMotion` state + freeze logic in `app.js`**
+
+Near `DEV_KEY`/`WARN_KEY`:
+
+```js
+const RM_KEY = "hef.reduceMotion";
+let reduceMotion = false;
+function isReduced() { return reduceMotion; }
+function initReduceMotion() {
+  const box = $("reduce-motion");
+  let stored = null;
+  try { stored = localStorage.getItem(RM_KEY); } catch (_) {}
+  // Default to the OS setting when the user hasn't chosen yet.
+  const prefers = window.matchMedia && window.matchMedia("(prefers-reduced-motion: reduce)").matches;
+  reduceMotion = stored === null ? !!prefers : stored === "1";
+  if (box) {
+    box.checked = reduceMotion;
+    box.addEventListener("change", () => {
+      reduceMotion = box.checked;
+      try { localStorage.setItem(RM_KEY, reduceMotion ? "1" : "0"); } catch (_) {}
+      applyReduceMotion();
+    });
+  }
+  applyReduceMotion();
+}
+function applyReduceMotion() {
+  if (reduceMotion) {
+    if (autoRaf) { cancelAnimationFrame(autoRaf); autoRaf = 0; }
+    vid.pause();
+    loopVid.pause();
+  } else if (videoEverOn && $("visual").checked) {
+    playLoop();
+  }
+}
+```
+
+- [ ] **Step 6: Make `autoScrub` instant under reduced motion**
+
+At the top of `autoScrub` (`app.js:678`), after the `if (!ring …) return;` guard, add:
+
+```js
+  if (isReduced()) {            // no autonomous tween — jump straight to the target
+    if (autoRaf) { cancelAnimationFrame(autoRaf); autoRaf = 0; }
+    setPos(targetPos);
+    return;
+  }
+```
+
+- [ ] **Step 7: Keep playback paused when reduced-motion is on after landing**
+
+In `beginExperience()` (`app.js:1250`) and wherever `playLoop()` is called on a settle, guard the play with `if (!isReduced()) playLoop();` — specifically wrap the settle-time `playLoop()` at `app.js:850` and the `beginExperience` start so turning the experience on while reduced does not animate. (Inspect each `playLoop()` call site; guard the autonomous ones, leave the explicit toggle-off resume in `applyReduceMotion`.)
+
+- [ ] **Step 8: Call `initReduceMotion()` in `main()`**
+
+After `initLanguage();` (`app.js:1266`) add:
+
+```js
+  initReduceMotion();          // reduced-motion state + toggle (default from OS pref)
+```
+
+- [ ] **Step 9: Run the reduced-motion test to verify pass**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "reduce-motion toggle"`
+Expected: PASS.
+
+- [ ] **Step 10: Commit**
+
+```bash
+git add simulator/static/index.html simulator/static/i18n.js simulator/static/app.js simulator/e2e/tests/a11y.spec.ts

+### Task 6: Keyboard + ARIA for the Altitude dial
+
+**Files:**
+- Modify: `simulator/static/index.html:56` (dial svg attrs)
+- Modify: `simulator/static/app.js` (keydown handler, aria-value sync, label buttons)
+- Test: `simulator/e2e/tests/a11y.spec.ts`
+
+**Interfaces:**
+- Consumes: `autoScrub`, `jumpToScale`, `ring`, `ringIndex`, `dialStep` (all in `app.js`).
+- Produces: `setDialAria()` updates `aria-valuenow/valuetext`; called wherever the needle settles.
+
+- [ ] **Step 1: Write the failing e2e test**
+
+Append to `a11y.spec.ts`:
+
+```ts
+test("altitude dial is keyboard-operable", async ({ page }) => {
+  await page.goto("/");
+  await page.locator("#motion-warning-continue").click().catch(() => {});
+  const dial = page.locator("#dial");
+  await expect(dial).toHaveAttribute("role", "slider");
+  await dial.focus();
+  const before = await page.locator("#scale-name").textContent();
+  await dial.press("ArrowDown");          // descend one altitude
+  await expect.poll(async () => page.locator("#scale-name").textContent()).not.toBe(before);
+  await dial.press("Home");               // jump to cosmos (top)
+  await expect(page.locator("#scale-name")).toHaveText(/cosmos|宇宙/i);
+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "keyboard-operable"`
+Expected: FAIL (dial has no `role`/key handling).
+
+- [ ] **Step 3: Add ARIA attrs to the dial in `index.html`**
+
+Change line 56 to:
+
+```html
+<svg id="dial" viewBox="0 0 100 100" role="slider" tabindex="0"
+     aria-label="Altitude — turn to change scale"
+     aria-valuemin="0" aria-valuenow="0" aria-valuetext="cosmos"></svg>
+```
+
+- [ ] **Step 4: Add `setDialAria()` and call it on settle**
+
+In `app.js`, add:
+
+```js
+// Reflect the committed altitude into the dial's slider semantics for AT.
+function setDialAria() {
+  if (!dial || !ring) return;
+  dial.setAttribute("aria-valuemax", String(ring.scales.length - 1));
+  dial.setAttribute("aria-valuenow", String(ringIndex));
+  const s = ring.scales[ringIndex];
+  if (s) dial.setAttribute("aria-valuetext", HEFi18n.pickUiString("scale." + s.id, activeLang));
+}
+```
+
+Call `setDialAria()` at the settle point in `setPos` where `setNeedle(ringIndex * dialStep())` runs on frac 0 (`app.js:852`), and once in `buildDial()` after the dial is drawn.
+
+- [ ] **Step 5: Add the keydown handler**
+
+```js
+function onDialKey(e) {
+  if (!ring || ring.scales.length < 2) return;
+  let handled = true;
+  switch (e.key) {
+    case "ArrowDown": case "ArrowRight": autoScrub(Math.round(pos) + 1); break;
+    case "ArrowUp":   case "ArrowLeft":  autoScrub(Math.round(pos) - 1); break;
+    case "Home": jumpToScale(0); break;
+    case "End":  jumpToScale(ring.scales.length - 1); break;
+    default: handled = false;
+  }
+  if (handled) e.preventDefault();
+}
+```
+
+Wire it in `main()` next to the other dial listeners (`app.js:1289`):
+
+```js
+  dial.addEventListener("keydown", onDialKey);
+```
+
+- [ ] **Step 6: Make the dial labels keyboard-activatable**
+
+In `buildDial()` (where each `.dial-label` is created, ~`app.js:749`), add to the label's attributes: `role: "button"`, `tabindex: "0"`, and an `aria-label` of the scale name. Then in `main()` add a delegated keydown on the dial that activates a focused label:
+
+```js
+  dial.addEventListener("keydown", (e) => {
+    const t = e.target;
+    if (t && t.classList && t.classList.contains("dial-label") && (e.key === "Enter" || e.key === " ")) {
+      e.preventDefault();
+      jumpToScale(+t.getAttribute("data-index"));
+    }
+  });
+```
+
+- [ ] **Step 7: Run the keyboard test to verify pass**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "keyboard-operable"`
+Expected: PASS.

+### Task 7: Screen-reader narration (aria-live) + hide decorative SVG
+
+**Files:**
+- Modify: `simulator/static/index.html` (aria-live region; `aria-hidden` on decorative layers)
+- Modify: `simulator/static/app.js` (announce on settle, throttled)
+- Test: `simulator/e2e/tests/a11y.spec.ts`
+
+**Interfaces:**
+- Consumes: `activeClipId`, the clip's resolved strings, `ring`, `ringIndex`.
+- Produces: `announce(text)`; `decorative SVGs are aria-hidden`.
+
+- [ ] **Step 1: Write the failing e2e test**
+
+Append to `a11y.spec.ts`:
+
+```ts
+test("an aria-live region narrates the current scale", async ({ page }) => {
+  await page.goto("/");
+  await page.locator("#motion-warning-continue").click().catch(() => {});
+  const live = page.locator("#sr-status");
+  await expect(live).toHaveAttribute("aria-live", "polite");
+  await page.locator("#dial").focus();
+  await page.locator("#dial").press("Home");
+  await expect.poll(async () => (await live.textContent())?.toLowerCase()).toContain("cosmos");
+});
+
+test("decorative overlay SVGs are hidden from AT", async ({ page }) => {
+  await page.goto("/");
+  await expect(page.locator("#overlay")).toHaveAttribute("aria-hidden", "true");
+  await expect(page.locator("#affect")).toHaveAttribute("aria-hidden", "true");
+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "aria-live|decorative"`
+Expected: FAIL.
+
+- [ ] **Step 3: Add the live region + aria-hidden in `index.html`**
+
+Add `aria-hidden="true"` to `#overlay`, `#affect`, `#tint`, `#paint`. Add inside `.panel` (top, after the opening tag) a live region:
+
+```html
+<div id="sr-status" class="visually-hidden" role="status" aria-live="polite"></div>
+```
+
+- [ ] **Step 4: Add `announce()` + call on settle in `app.js`**
+
+```js
+let lastAnnounced = "";
+function announce(text) {
+  const el = $("sr-status");
+  if (!el || !text || text === lastAnnounced) return;
+  lastAnnounced = text;
+  el.textContent = text;
+}
+// Build the spoken summary: scale + top factual (left) label for the active clip.
+function announceState() {
+  if (!ring) return;
+  const s = ring.scales[ringIndex];
+  const scaleName = s ? HEFi18n.pickUiString("scale." + s.id, activeLang) : "";
+  const clip = activeClip && activeClip();   // use existing accessor for the locked clip
+  let label = "";
+  if (clip) {
+    const strings = HEFi18n.resolveStrings(clip.strings, activeLang);
+    label = firstFactualLabel(strings) || "";
+  }
+  announce(label ? `${scaleName}. ${label}` : scaleName);
+}
+```
+
+If no `activeClip()` accessor exists, read the locked clip via the existing `activeClipId` lookup used in `renderScaleReadout` (mirror that code). `firstFactualLabel` returns the first non-empty left/`LABELS`-style string from `strings`; if the shape makes this awkward, announce just `scaleName` (degrade gracefully — the scale name is the load-bearing part).
+
+Call `announceState()` at the same settle point as `setDialAria()` (frac 0 in `setPos`) and at the end of `setLanguage()` so a language switch re-announces.
+
+- [ ] **Step 5: Run the narration tests to verify pass**
+
+Run: `cd simulator/e2e && npx playwright test a11y.spec.ts -g "aria-live|decorative"`
+Expected: PASS.

+### Task 8: Apply the flash audit to real transitions
+
+**Files:**
+- Modify: `simulator/static/app.js` and/or `simulator/static/style.css` (clamp the audited transitions)
+- Modify: `simulator/static/index.html` (load `flash.js` before `app.js`)
+
+**Interfaces:**
+- Consumes: `HEFFlash.clampDurationMs` (Task 3).
+
+- [ ] **Step 1: Load `flash.js` in `index.html`**
+
+Add before `app.js` (after `i18n.js`, `index.html:117`):
+
+```html
+  <script src="flash.js"></script>
+```
+
+- [ ] **Step 2: Audit + enumerate the rapid-luminance transitions**
+
+Inspect the three sources and record findings as a comment in `app.js` above the change:
+1. Fast-spin blended dial pass — `autoScrub` total `ms = perAltMs * |dist|`; the per-altitude floor is 1200ms (well under 3/sec for one step), so a multi-step spin is already ≥3 transitions over ≥N×1.2s = safe. Confirm and note.
+2. `#black` cover fade — `style.css` `transition: opacity 200ms`; a single fade is one transition, not a repeated flash — safe.
+3. Audio-coupled crossfade — visual? If it drives an opacity swap, check its duration.
+
+For any source that CAN repeat faster than 3/sec (e.g. a rapid wheel/keyboard repeat firing `autoScrub` back-to-back), clamp using `HEFFlash`:
+
+```js
+  // Guard against a fast key/wheel repeat producing >3 luminance swings/sec.
+  const safeMs = HEFFlash.clampDurationMs(PER_ALTITUDE_MS, 1);
+```
+
+If the audit finds NO breach (the likely outcome given the 1200ms floor), record that conclusion in the comment and make no timing change beyond loading `flash.js` for the helper's availability — do not invent a clamp that isn't needed (YAGNI). The deliverable of this task is the documented audit + `flash.js` wired in.
+
+- [ ] **Step 3: Run existing e2e to confirm no regression**
+
+Run: `cd simulator/e2e && npx playwright test altitude-lock.spec.ts`
+Expected: PASS (12 tests, per project memory).

+      <p>The <em>Human Experience Filter</em> is built to be accessible to — and
+      representative of — the full range of human experience. That is why it works
+      with a keyboard, with a screen reader, with reduced motion, and away from any

+      <h2>Places technology let us see</h2>
+      <p>The scales you move through — the deep sea, the coast, the sky, the orbit

+      ever witness. We can share them only because our tools evolved to reach them:
+      from <strong>underwater exploration</strong>, to <strong>drones and aerial
+      imaging</strong>, to <strong>space exploration</strong>. Each scale is a place

+    </section>
+
+    <section>
+      <h2>Built with LLMs</h2>
+      <p>This piece was itself built using large language models — an extension of

+      software, the words, and much of the craft were shaped in collaboration with
+      a machine.</p>

+
+    <section>
+      <h2>Honest about its limits</h2>
+      <p>This implementation is imperfect. It is also more than I could have made
+      alone: better with these tools assisting than by my hand as a single human.
+      That tension is part of the point — technology does not replace the person
+      behind the work; it extends their reach, flaws and all.</p>

+## Self-Review
+
+**Spec coverage:** A1 reduced-motion → Task 5; A2 gate → Task 4, audit → Tasks 3+8; B keyboard/focus → Tasks 2+6; C contrast → Task 2; D SR narration → Task 7; E about.html → Task 9; F layout → Task 1. `<html lang>` correctly omitted (already done). All covered.
+
+**Placeholder scan:** Code shown for every code step. Task 7's `firstFactualLabel`/`activeClip` note explicitly degrades to scale-name-only if the clip-strings shape is awkward — that is a defined fallback, not a placeholder. Task 8 explicitly allows a "no breach found → document and stop" outcome (YAGNI), which is a real deliverable.
+
+**Type consistency:** `isReduced()`, `autoRaf`, `setPos`, `autoScrub`, `jumpToScale`, `setDialAria`, `announce`, `HEFFlash.clampDurationMs`, `WARN_KEY`/`RM_KEY` used consistently across tasks. `reduce-motion` element id matches between HTML (Task 5 Step 3) and JS (Task 5 Step 5) and test.

+# Accessibility pass + About page — Solution Design
+
+**Date:** 2026-06-30
+**Branch:** `feat/accessibility-pass` (off `design/cloudflare-static-publish`)
+**Status:** Draft — pending operator review
+
+## Problem
+
+The simulator was built for an attended **kiosk**: a known display, a person
+nearby, no assistive technology in the loop. The Cloudflare static publish
+(`design/cloudflare-static-publish`) puts the same experience on a public URL
+(`benstull.art`) where none of those assumptions hold. That raises two bars at
+once:
+
+- **Legal/usability** — a public site is expected to meet WCAG 2.1 AA; today the
+  primary navigation control (the Altitude dial) is pointer-only, several text
+  colors fail contrast, and there is no screen-reader path into a piece whose
+  *meaning* is already textual.
+- **Physical safety** — the piece is continuous motion (video morphs, auto-scrub,
+  crossfades, a "trippy at max" WebGL shader, black-cover fades) with no
+  `prefers-reduced-motion` support and no photosensitivity safeguard. Unattended,
+  that is a vestibular and seizure risk.
+
+This work makes the *experience* (not just the chrome) usable away from the
+kiosk, and adds an **About** page explaining what the piece is for.
+
+## Goals
+
+1. Honor reduced-motion and add seizure safety (the public-web-specific layer).
+2. Make every control keyboard- and screen-reader-operable.
+3. Fix low-vision contrast.
+4. Add `about.html` — the project's intent and provenance.
+5. A small Output-panel layout fix (language picker placement).
+
+**Non-goals:** no engine/Python changes; no new languages (about page is
+English-first, i18n-keyed for later); no RTL; no redesign of the visual art.
+The `<html lang>` switch is **already implemented** (`applyUiStrings`,
+`app.js:1325`) and is out of scope.
+
+## Target
+
+WCAG 2.1 **AA** as the baseline, plus a motion/seizure layer (WCAG 2.3.1 flash
+threshold + 2.3.3 animation-from-interactions) on top, since those are the risks
+that genuinely change when the piece leaves the kiosk.
+
+## Design
+
+All changes are client-side, in `simulator/static/`. Seven units.
+
+### A1. Reduced-motion: freeze-to-stills
+
+A single `reduceMotion` state, default-on when
+`window.matchMedia('(prefers-reduced-motion: reduce)').matches`, plus a visible
+toggle in the Output fieldset (so a visitor whose OS setting disagrees can
+override either way). Persisted in `localStorage` (mirrors the existing `devMode`
+pattern, `app.js:934`).
+
+When `reduceMotion` is **on**:
+
+- **Video holds a frame.** Pause `#vid` / `#vid-loop` (do not call `playLoop()` /
+  the `.play()` paths at `app.js:260,288`). The Kuwahara paint loop keeps running
+  but composites a *static* frame, so knob changes (mood grade, dream, labels)
+  still re-render — the image responds, it just doesn't animate on its own.
+- **Transitions are instant, not animated.** `autoScrub()` (`app.js:678`) jumps
+  `pos` straight to the target (one assignment + a single settle render) instead
+  of driving the rAF tween. Dial drag still scrubs live under the finger (that is
+  a direct-manipulation gesture, not autonomous motion — allowed under 2.3.3),
+  but on release it settles without a spin.
+- **Auto-scrub speed coupling is disabled** (the constant per-altitude auto-spin).
+
+The toggle flips state live (no reload): turning it off resumes `playLoop()`;
+turning it on pauses and holds.
+
+### A2. Photosensitivity: warning gate + flash audit
+
+- **Warning gate.** A one-time interstitial over the stage, shown with the
+  existing `#run-sim` flow before the experience begins: a short "contains motion
+  and flashing effects" notice with a **Continue** action. Dismissal is
+  remembered in `localStorage` so it shows once per visitor, not every load. It
+  reuses the run-sim z-layer (above the black cover) and does not block the rest
+  of the page (controls remain reachable).
+- **Flash audit.** Review the three motion sources that can produce rapid
+  luminance swings — the fast-spin blended dial pass, the `#black` cover fades
+  (`app.js`/`style.css`), and audio-coupled crossfades — and clamp any that can
+  exceed **3 transitions/second** (WCAG 2.3.1). The clamp math (min transition
+  duration given a luminance delta) is a **pure function** in a small module so it
+  is unit-testable; the audit findings and any clamps are recorded in the
+  implementation plan.
+
+### B. Keyboard + focus
+
+- **Dial as a real slider.** The `#dial` SVG gets `role="slider"`, `tabindex="0"`,
+  and live `aria-valuemin` / `aria-valuemax` / `aria-valuenow` / `aria-valuetext`
+  (the human scale name, e.g. "reef"). A `keydown` handler maps:
+  - `ArrowDown` / `ArrowRight` → descend one altitude (`+1`, matching wheel-down).
+  - `ArrowUp` / `ArrowLeft` → ascend one altitude (`-1`).
+  - `Home` → cosmos (index 0); `End` → the deepest scale.
+  - Each step calls the existing `autoScrub` / `jumpToScale` path (so reduced-motion
+    instant-jump is inherited for free).
+- **Dial labels become buttons.** The tap-to-jump `.dial-label` nodes get
+  `role="button"` + `tabindex="0"` + Enter/Space activation, reusing `jumpToScale`.
+- **Visible focus everywhere.** A global `:focus-visible` outline rule (today only
+  `.dev-switch` has one).
+
+### C. Low-vision contrast
+
+Bump the failing dark-on-dark text to meet AA (4.5:1 for body, 3:1 for large):
+the panel `.hint` (`#789`), `.dial-caption` (`#4d6184`), `.dial-label` (`#789ac0`),
+and any others a contrast check flags on the `#111` / `#0d1320` backgrounds.
+Verify the 280px panel reflows and text scales to 200% without clipping.
+
+### D. Screen-reader basics
+
+- Ensure every control has an accessible name (sliders via their `<label>`; the
+  dial via `aria-valuetext`; the new toggle labeled).
+- **Narrate the alteration.** A visually-hidden `aria-live="polite"` region
+  announces the current scale and the active clip's top factual (left-brain)
+  label as the altitude/knobs change — turning the visual alteration into words.
+  Updates are throttled/debounced so a drag doesn't flood the queue.
+- The decorative HUD/affect SVG layers get `aria-hidden="true"`.
+
+### E. about.html
+
+A standalone page mirroring `credits.html` exactly (same `credits-page` /
+`credits-wrap` styles, a `← Back to the experience` link, `config.js` loaded).
+English prose, structured so it can be i18n-keyed later. Linked from the header
+beside the existing Credits link (`index.html:18`). Narrative beats:
+
+- **For everyone.** The piece aims to be accessible to, and representative of,
+  the full range of human experience — which is *why* this accessibility work
+  exists.
+- **Vantage points technology gave us.** The scales — deep-sea, coast, sky,
+  drone/aerial, orbit, cosmos — are places no unaided human could witness. We can
+  share them only because technology evolved to reach them: **underwater
+  exploration → drones → space exploration.**
+- **Built with LLMs.** The work itself was built using large language models — an
+  extension of that same arc of tools extending human reach.
+- **Honest about its limits.** This implementation is **imperfect** — but it is
+  more than the author could make alone; better *with* LLMs assisting than by a
+  single human hand. The imperfection is part of the point: tools extend us, they
+  don't replace the human behind them.
+
+### F. Layout fix (Output fieldset)
+
+Move the language picker **below** the Audio control (currently it sits above
+Video/Audio). Put the globe `🌐` inline to the **left** of the `<select>` via a
+flex row — today `.lang-pick` has no CSS, so the full-width `select` rule
+(`style.css` `select { width: 100% }`) pushes the globe onto its own line above.
+Add a `.lang-pick { display:flex; align-items:center; gap }` rule and let the
+select flex to fill the rest.
+
+## Components / files
+
+| File | Change |
+| --- | --- |
+| `index.html` | Reduced-motion toggle; warning-gate markup; aria-live region; dial a11y attrs; move lang picker below Audio; about-page header link |
+| `style.css` | `.lang-pick` flex; contrast bumps; `:focus-visible`; visually-hidden util; warning-gate styles |
+| `app.js` | `reduceMotion` state + freeze logic; dial keyboard handler + aria-value sync; label buttons; aria-live narration; gate dismissal |
+| `flash.js` *(new, pure)* | Flash-clamp helper (min duration given luminance delta), UMD like `i18n.js`/`credits.js` |
+| `i18n.js` | New UI keys for the toggle, warning gate, about link (EN populated; other langs may fall back) |
+| `about.html` *(new)* | The page above |
+| `tools/build_static.py` | Ensure `about.html` + `flash.js` are copied into `dist/` (verify the static build includes new static files) |
+
+## Testing
+
+- **Node unit tests** for the pure flash-clamp helper (`flash.js`) — boundary
+  cases around the 3/sec threshold.
+- **Playwright e2e** (extends the existing suite): reduced-motion toggle pauses
+  video and makes a dial step instant; dial is keyboard-focusable and
+  Arrow/Home/End change the scale; the warning gate appears and dismisses once;
+  `about.html` loads and its back-link returns to `index.html`; the language
+  picker renders below Audio with the globe inline.
+- **Manual/automated contrast check** on the bumped colors.
+- Existing suites stay green: the current Playwright specs, node `--test`, and
+  `pytest`.

+```
+Add left and right brain annotations (including localization) for any that are missing.
+```
+
+## Plan
+
+> Anchor: operator direct instruction (standalone leaf content-fill task, §4.3 R2b).
+
+**Goal:** Author the missing **left-brain** factual `LABELS` (tiered general→scientific→+fact
+labels) for the rotating-pool clips that lack them, plus their **es/fr/ja** translations,
+then rebuild + merge the manifest. Right-brain `affect` is auto-generated per scale for
+every clip via `_affect_for_clip` — nothing missing there.
+
+## Pre-state
+
+- `main` at `5beee55` locally but **diverged from `origin/main`**: 11 merged-but-unpushed
+  commits (the entire i18n localization feature + a video-loop safety-net fix) stranded
+  locally; `origin/main` still at `eff43bd` (PR #29). Plus 3 files with an uncommitted
+  "boots-silent / no auto-start" change. Two stale `--INPROGRESS` placeholders (0015, 0017).
+- Annotation reality (from a read-only survey of `build_pool_manifest.py` + catalogs):
+  right-brain `affect` present on all 41 clips (auto-per-scale); left-brain `LABELS`
+  present on only 13 of 41. 28 pool clips had `"annotations": []`.
+
+## Arc
+
+1. **Scoped the task** — explored the annotation/i18n system; established that the gap was
+   left-brain only (right-brain is auto-generated), 28 clips, + their es/fr/ja strings.
+2. **Claimed session 0027** (peek showed the two stale placeholders; noted + proceeded).
+3. **Surfaced the unclean baseline**; operator chose *"Push stranded, also commit dirty."*
+   - Stashed the 3 dirty files, merged `origin/main`'s claim commit, **pushed the 11
+     stranded commits** (`020219f`).
+   - Committed the boots-silent change on `fix/boot-silent-no-autostart`, verified
+     (299 pytest pass), **merged + pushed** (`7bd6c9a`).
+4. **Annotation work** on `feat/left-brain-annotations`:
+   - Added 28 `LABELS` entries (static tiered labels) to `build_pool_manifest.py`
+     (Round-5 block); rebuilt manifest → all 41 clips annotated; extracted en catalog.
+   - Dispatched **3 parallel translator subagents** (es/fr/ja) for the 67 new keys,
+     matching existing catalog voice; fixed 2 ja `measure.*` values to the `約`/localized
+     convention; merged fragments into catalogs; merged all 3 langs into the manifest.
+   - Verified: 41 clips × en/es/fr/ja full key + tier-length parity; 299 pytest pass
+     (3 pre-existing `cv2` env failures only); 37 i18n/manifest tests green; spot-checked
+     translations. **Merged + pushed** (`934f60c`), deleted both branches.
+
+## Cut state
+
+- `main` == `origin/main` @ `934f60c`, clean tree, branches removed.
+- 41/41 clips carry left+right annotations with full en/es/fr/ja parity.
+- §9: local tests green. No PPE/E2E machinery exists for this app yet (pipeline is policy,
+  not automated — §10.6); prod promotion stays operator-gated. Visual review deferred to
+  operator (no Chrome on box).
+
+## Operator plate
+
+- **Review by eye** the 28 newly-labelled clips across all 4 languages in the running sim.
+- The labels are **static**; the abyss/reef *creature* clips would benefit from a later
+  **tracked-label** upgrade via author mode (couldn't auto-file as a tracker issue — the
+  capture token returned 401 in this env; full context is in the session-0027 memory note).
+- A few species IDs were inferred from clip META, not the frame (`reef_redsea`→anthias,
+  `reef_flowergarden`→jack/scad+sergeant-major) — worth confirming at review.
+- Two stale `--INPROGRESS` sessions (0015, 0017) remain unfinalized — likely the crashed
+  sessions that stranded the 11 commits; left untouched for the operator.
+
+## Next-session prompt
+
+```
+/goal Review the new left-brain annotations (all 28 newly-labelled pool clips, across en/es/fr/ja) by eye in the running simulator; correct any species/box that reads wrong, and decide whether the abyss/reef creature clips should get tracked labels via author mode.
+```
+
+## Deferred decisions
+
+- **Static labels, not tracked.** Authored all 28 clips' left-brain labels as fixed-box
+  `static_label`s rather than motion-tracked labels. Alternative: tracked labels (as the
+  reef/abyss showcase clips use) so the box follows drifting creatures. Chose static because
+  the footage wasn't eyeballed — fabricating track coordinates would claim precision I don't
+  have. The abyss/reef creature clips are the ones that would most benefit from a later
+  tracked-label upgrade via author mode.
+- **Some species IDs inferred from clip metadata, not the footage.** `reef_redsea`→anthias,
+  `reef_flowergarden`→jack/scad + sergeant-major — read from the clip META title/source.
+  High-confidence from provenance, but worth an eyeball check.
+- **`O-type` kept verbatim in es/fr/ja** (per the translation brief) rather than the more
+  natural `tipo O` / `type O`. Minor; flagged by the es translator.

+
+## Launch prompt
+
+`/goal next` — operator then directed: "There's a concurrent session — do this one out
+of a worktree in a different dir." Session 0028 runs isolated in worktree
+`worktree-session-0028` while a concurrent session owns the simulator startup ("Run
+simulation" button: `index.html`/`style.css`/`i18n.js`).
+
+## Plan
+
+> Anchor: leaf bug — D3 reverse-landing frame jump (no tracker issue; the s0027 capture
+> token returned 401. Residual flagged in the altitude-morph-and-scrub memory note +
+> scrub-driven-transitions design.)
+
+**Goal:** kill the ~3-second frame jump when ASCENDING the altitude dial and landing on
+the higher-altitude clip.
+
+**Root cause (verified by reading the bake + player):** each baked morph
+`transitions/{h}__{l}.mp4` spans `src(h)@0s` (frac 0) → `dst(l)@~LOOP_TAIL_S` (frac 1),
+and the scrub uses this single forward file in BOTH directions. The steady loop element
+always seeks to `LOOP_TAIL_S` (3.0s) on landing. So:
+- DESCEND (dir>0) lands on `dst` at frac 1 → morph ends `dst@3` ≈ loop@3 → seamless ✓
+  (the s0026 "loop-from-tail" fix).
+- ASCEND (dir<0) lands on `src` at frac 0 → morph shows `src@0`, but loop seeks `src@3`
+  → ~3s jump ✗ (D3).
+
+**Fix (app-side, no media re-bake — beats re-baking 154 LFS morphs):** make the loop
+landing frame DIRECTION-AWARE. On a reverse landing seek the loop to 0 (= the morph's
+frac-0 frame) and wrap `[0,dur]` (the base is already a seamless crossfade-loop); forward
+keeps `[LOOP_TAIL_S,dur]`. Pure decision extracted to `scrub.js loopLandFrame(dir,
+loopTailS)` + node tests; wired through `loadLoop`/settle/wrap handlers in `app.js`.
+
+**Tasks:**
+1. TDD `HEFScrub.loopLandFrame(dir, loopTailS)` in `scrub.js` (+ `scrub.test.js`).
+2. Wire `app.js`: `loadLoop(clip, landFrame)`, directional settle seek, `dataset.loopStart`
+   in the `timeupdate`/`ended` wrap handlers.
+3. Add a reverse-landing e2e (mirror of the existing forward "loops from tail" test).
+4. Verify: node unit tests + pytest + e2e (best-effort) all green.
+5. Branch → PR → merge (yolo). PPE/E2E machinery not built for this app (§10.6) — local
+   green is the bar; prod promotion stays operator-gated.
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Appended as the session runs; surfaced at
+finalize. Empty if none._
+
+- **Fix shape: app-side direction-aware loop landing, NOT a 154-morph re-bake.** The
+  s0026 memory note guessed the D3 fix would be "per-clip loop files." Reading the bake +
+  player showed the root cause is simpler: the morph's frac-0 frame is `src@0` but the
+  loop always seeked the tail (`LOOP_TAIL_S`). Fixed entirely in `app.js`/`scrub.js` by
+  landing the loop on the morph's actual frac-0 frame (0) when ascending. This avoids
+  re-baking 154 LFS morphs (no media churn, a tiny reviewable diff, the base clips are
+  already seamless crossfade-loops so `[0,dur]` wraps cleanly). Alternative considered:
+  re-bake morphs to start at `src@LOOP_TAIL_S` — heavier, no benefit.
+- **Pre-existing e2e failure left as-is:** `loop-recovery.spec.ts` fails in this
+  environment on the CLEAN baseline too (verified by stashing my changes). It boots
+  without enabling video, so the loop's `loopTail` is never armed and the `ended` guard
+  returns early. Not introduced here; my change preserves that guard exactly. Worth a
+  separate look (the test likely needs to `enableVideo` first), but out of scope for D3.
+- **Could not verify by eye.** The fix is logic- and test-verified (node + the new
+  reverse-landing e2e asserting the loop anchors at the head, not the tail); the actual
+  visual seamlessness of an ascending landing still wants an operator eyeball in the
+  running sim.
+
+## Session arc
+
+1. Claimed session **0028** (race-free, via git). Two stale `--INPROGRESS` placeholders
+   (0015, 0017) noted as orphaned, left untouched.
+2. Baseline survey surfaced uncommitted `run-sim` button edits + main behind by 2
+   (session commits). Operator confirmed a **concurrent session** owns that startup work
+   and directed isolation → created worktree `worktree-session-0028` off `origin/main`,
+   leaving the concurrent session's edits in the canonical clone untouched.
+3. Orientation: in-repo `docs/ROADMAP.md` is stale (formal frontier = deferred hardware);
+   live frontier is in memory. Stored `/goal next` (0027's by-eye annotation review) is
+   operator-eyes work I can't complete; the run-sim button is the concurrent session's.
+   Asked the operator to pick 0028's disjoint item → **D3 reverse-landing fix**.
+4. Read the bake (`build_pool_manifest.transition_cmd`) + player (`app.js` loop/morph) to
+   pin the root cause (morph spans `src@0`→`dst@tail`; loop always seeks the tail).
+5. TDD: `HEFScrub.loopLandFrame` (red → green), then wired `app.js`
+   (`loadLoop(clip,landFrame)`, `dataset.loopStart`, directional settle, wrap handlers).
+6. Added a reverse-landing e2e. Verified: node 16/16, **altitude-lock e2e 12/12** (forward
+   no-regression + new reverse test), pytest 299 pass. Confirmed `loop-recovery.spec.ts`
+   fails on the clean baseline too (pre-existing, not mine) by stashing.
+7. Committed → PR #30 → merged to `main` (`582183d`) → deleted branch. Updated memory.
+
+## Cut state
+
+- **On `main` (`582183d`):** D3 fix — `simulator/static/scrub.js` (+`loopLandFrame`),
+  `simulator/static/app.js` (direction-aware loop landing), `simulator/unit/scrub.test.js`,
+  `simulator/e2e/tests/altitude-lock.spec.ts` (reverse-landing test).
+- **Tests:** node 16/16; altitude-lock e2e 12/12; pytest 299 pass / 3 pre-existing
+  env-only failures (real-ffprobe/ffmpeg + ML detect; untouched — no Python changed) / 4
+  skipped. `loop-recovery.spec.ts` is a pre-existing baseline failure in this env.
+- **§9 / deploy:** this whole project is **exempt** from flotilla/PPE/§9 (memory:
+  project-exempt-from-wiggleverse-deploy; public target is static Cloudflare). Local-green
+  is the bar — met. No PPE stage to run.
+- **No plan artifact archived:** fused leaf fix, plan inline in this transcript; app has
+  **no content repo** (`CONTENT_REMOTE` empty) — nothing to archive.
+
+## Operator plate
+
+- **Review by eye** an ASCENDING altitude landing in the running sim — confirm the
+  ~3s reverse-landing jump is gone (logic/test-verified only; no Chrome on box here).
+- Still standing from s0027: by-eye review of the 28 left-brain annotations (4 langs);
+  decide on tracked labels for abyss/reef creature clips.

+## Launch prompt
+
+"We need to make sure credits for Creative Commons licensed videos are compliant.
+What are some options?" → after presenting options the operator chose **Option A**
+(manifest-driven static credits/colophon page surfaced to the public) + **Option D1**
+(declare the altered footage CC BY-SA 4.0). Non-commercial.
+
+## Pre-state
+
+- Branch `design/cloudflare-static-publish` (static-publish work, pushed). Working
+  tree had uncommitted, unrelated in-flight work: a "Run simulation" start button
+  (6 files) **plus** an `r2-cors.json` reformat (surfaced via stash, 7 total).
+- Per-clip `license`/`source` already in `clips.json` (baked from `/api/clips`) but
+  only shown in the dev panel + internal review pages — public experience showed none.
+- A concurrent session was live in worktree `fix+audio-and-tracking-labels` (off main);
+  the operator was also committing directly to `design/cloudflare-static-publish`.
+
+## Arc
+
+1. **Audited** the license surface: `tools/licensing.py`, `pipeline/provenance.py`,
+   manifest, frontend. Found credits exist in data + review tooling but not the public
+   experience → that's the gap. Presented options A–D; operator chose A + D1.
+2. **Claimed session 0029** (planning-and-executing, yolo). Two stale `--INPROGRESS`
+   placeholders (0015, 0017) noted as long-dead, left alone.
+3. **Operator-requested pre-work:** the uncommitted in-flight work. Stashed it,
+   created an isolated worktree (`.claude/worktrees/session-0029` off the branch HEAD,
+   since the static work lives there not on main), applied the stash.
+   - Discovered the branch had advanced under me to `8cc472c` (operator's direct
+     commit). It **intentionally** keeps `r2-cors.json` in S3-array form alongside a
+     new `r2-cors.wrangler.json` (runbook documents both) → **dropped** my conflicting
+     `r2-cors.json` reformat commit; kept + rebased only the Run-simulation button.
+   - Committed the button (`3a45e33`), ff-merged + pushed.
+4. **Built Option A + D1** (TDD): node test for the pure credits logic first (red) →
+   `credits.js` (UMD: `creditEntries`/`creditsListHtml`, escaped, sorted) → `credits.html`
+   colophon (D1 CC BY-SA declaration + "altered" note; JS-filled video attributions;
+   PD/CC0 audio courtesy block; back link) → header "ⓘ Credits" link (`credits.link`
+   i18n en/es/fr/ja) → `style.css` → `PUBLIC_ASSETS` in `build_static.py` + its test →
+   Playwright e2e (`tests/test_e2e_credits.py`).
+5. **Verified:** node 28/28, pytest 315 passed / 2 skipped. Real build render: 41/41
+   clips credited, all 7 CC-BY/BY-SA clips show required attribution, 0 missing.
+   Committed (`1c7f2b7`), ff-merged + pushed, removed the worktree, deleted the branch.
+
+## End state
+
+- `design/cloudflare-static-publish` @ `1c7f2b7`, clean, pushed (origin in sync).
+- Public site now attribution-compliant: credits reachable from the work; altered-work
+  license declared. §9 is **exempt** for this project (static Cloudflare target), so
+  merged+pushed to the design branch is the completion state — no PPE/prod.
+
+## Deferred decisions
+
+- **Dropped my `r2-cors.json` reformat** rather than merging it — concluded from the
+  operator's `8cc472c` + runbook that the S3-array form is intentional. (Alternative:
+  keep both forms / ask. Chose to honor the documented two-file split.)
+- **Audio credits as a static courtesy block** in `credits.html` rather than plumbing
+  `audio_license` through the manifest/API. Rationale: audio is all PD/CC0 (no legal
+  attribution duty) and not machine-readable; data-plumbing was out of scope. (Alternative:
+  add audio license fields — deferred, low value for non-commercial PD/CC0.)

+
+## Plan
+
+1. Map the splash/loading flow and the Video/Audio toggle wiring (Explore agent
+   + direct reads of `simulator/static/{index.html,app.js,style.css,i18n.js}`).
+2. Add a `#run-sim` button inside the stage `.screen`, hidden until media
+   preloads, styled to sit above the black cover (`z-index: 60`).
+3. Add a `beginExperience()` helper: Video on + audio snapped to a
+   `START_AUDIO_LEVEL = "2"` + button dismissed + soundtrack played in-gesture
+   (Safari unlock). Wire it to both the button click and the first direct
+   Video-on (`!videoEverOn`).
+4. Reveal the button after `hideLoading()`; change the old 3/10 coupling → 2/10.
+5. Localize `run.button` in en/es/fr/ja (4-lang parity invariant).
+6. Update E2E coverage (pytest-playwright + Playwright TS) from the old
+   "couples to 3" assertions to 2; add button-shown / button-starts /
+   direct-video-on tests.
+7. Run the full suite + confirm a pre-existing failure is not mine.
+
+## Pre-session state
+
+- Branch `main` clean at `934f60c` (left-brain annotations merged). Simulator
+  boots SILENT (video off, audio 0) and waited for the operator to flip the
+  unlabelled **Video** toggle as the start gesture — not obvious to a first-time
+  viewer. First-Video-on coupled audio to **3/10**.
+- No session-init gate was run at the top of this session — it was treated as a
+  small, fully-specified frontend change (see Deferred decisions).
+
+## Turn-by-turn arc
+
+1. **Explore + direct reads.** Dispatched an `Explore` subagent to map the
+   splash + AV-toggle code; in parallel read `index.html`, `app.js`
+   (`main()`/`hideLoading()`/`beginExperience` region, the audio dial, the
+   `videoEverOn` coupling), `style.css` (`#loading`, `.black z-index:50`,
+   `.hidden`), and `i18n.js` (UI_STRINGS shape, 4 languages). Confirmed the
+   stage `.screen` is `position: relative` and the black cover is `z-index: 50`,
+   so a start button needs `z-index > 50` inside the screen and the side panel
+   (Video toggle) stays reachable.
+2. **Implement.** Added `#run-sim` to the stage; `.run-sim` CSS (centered pill,
+   `z-index: 60`); `run.button` i18n string (en/es/fr/ja); `beginExperience()`
+   unifying both entry paths; revealed the button after `hideLoading()`;
+   simplified the Video-toggle handler to call `beginExperience()` on first
+   on; changed coupling 3 → 2.
+3. **Update tests.** Replaced the old `test_video_on_couples_audio_to_three…`
+   (pytest) and the "couples audio to 3/10" Playwright TS test with 2/10
+   variants; added button-shown-after-load, button-starts-video+audio, and
+   direct-Video-on-dismisses-button cases on both harnesses.
+4. **Verify.** `303 passed, 2 skipped` (non-E2E pytest); `8 passed`
+   pytest-playwright (incl. 3 new); `12 passed` Playwright `altitude-lock.spec`
+   (incl. updated + new). Node unit tests (i18n / index-i18n / scrub) green; the
+   i18n completeness invariant confirms `run.button` has all 4 langs.
+5. **Isolate a failure.** `loop-recovery.spec.ts` failed; stashed only the
+   source files and re-ran on a clean baseline — it **fails identically without
+   my changes**, so it's pre-existing, not introduced here. (During that stash
+   round-trip a `test-results/.last-run.json` artifact briefly blocked
+   `git stash pop`; recovered by `git checkout`-ing the artifact and popping —
+   no source lost.)
+6. **Handed the working tree back uncommitted** for an operator by-eye review
+   (the project's usual cadence — no Chrome on the box). Offered to branch + PR.

+## What lands on the operator's plate
+
+- **By-eye / by-ear review** of the Run-simulation button in a real browser —
+  especially the **in-gesture audio unlock on real Safari/iOS** (headless tests
+  relax autoplay, so it's wired-but-unconfirmed on a real device).
+- The button work lives on `design/cloudflare-static-publish` alongside the
+  CC-credits + Cloudflare-publish work; it merges to `main` / ships when that
+  branch does (session 0029's frontier), not separately.
+- Note the concurrency: this session authored the change; session 0029 committed
+  it. Two transcripts (0029, 0030) touch the same single commit `3a45e33` —
+  expected, not a duplicate of the commit.
+
+## Prompt the operator can paste into the next session
+
+```
+/goal operator eyeball review of the static build (incl. the new Run-simulation button) + execute the real Cloudflare deploy to benstull.art/human-experience-simulator, per the cloudflare-static-publish design on branch design/cloudflare-static-publish
+```
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls; surfaced at finalize._
+
+1. **No session-init gate at the top.** Treated the task as a small,
+   fully-specified frontend tweak and implemented directly without claiming a
+   transcript first. Consequence: the work landed on a shared checkout and was
+   committed by a concurrent session (0029) rather than carrying its own
+   end-to-end branch→PR. Alternative: claim a session + isolated worktree up
+   front. Flagged because shared-checkout work is what the worktree rule guards
+   against.
+2. **`beginExperience()` snaps audio to 2 unconditionally** on first Video-on,
+   overriding a viewer who pre-set a higher level before pressing start /
+   flipping Video. Matched the operator's explicit "snap to audio level 2"
+   wording; alternative was to only raise from 0 (the prior 3/10 behavior). Easy
+   to soften to "only if currently 0" if undesired.
+3. **Real-device audio autoplay unverified.** Headless Chromium ran with
+   `--autoplay-policy=no-user-gesture-required`, masking real Safari/iOS
+   behavior; the in-gesture unlock is wired but needs a by-ear check.

+
+## Launch prompt
+
+Follow-up to session 0029's credits work. Operator's first ask was to rename the
+credits URL → "about" (one page holding both about + credits) and add an
+Accessibility table. Mid-clarification the operator redirected: **keep About and
+Credits separate** (the About page is owned by a parallel session) and simply
+**"Remove the 'About this work' from the credits page. I'll merge that into the
+About page on the other session."**
+
+## What I found before acting
+
+- The Cloudflare site is now **LIVE** (`benstull.art/human-experience-simulator`);
+  the branch had advanced several commits since s0029 (live deploy, progressive
+  boot, an audio mediaBase fix), and moved again mid-session (`a68d0bc`→`d10ffca`).
+- A **live concurrent session** owns `feat/accessibility-pass` with an
+  approved-pending design spec (`docs/superpowers/specs/2026-06-30-accessibility-and-about-page-design.md`):
+  a full WCAG 2.1 AA pass + a **separate `about.html`**. I surfaced the overlap with
+  the operator's original (one-page) ask; the operator resolved it by keeping the
+  pages separate and narrowing my task to the section removal.
+
+## Arc
+
+1. Surveyed git + the concurrent worktrees; read the a11y design spec.
+2. Started to raise a coordination question; operator interrupted with the narrow
+   instruction (remove "About this work" from credits; they move it to About).
+3. Claimed **session 0031**, isolated worktree off the live branch tip (`d10ffca`)
+   — only `credits.html` + its tests touched, so no overlap with the a11y session's
+   files (`index.html`/`style.css`/`app.js`/`about.html`).
+4. Removed the `<section class="declaration">` "About this work" block from
+   `credits.html`; rewrote the footage note to be self-contained ("All footage is
+   altered in real time in the experience" — keeps the per-clip modification cue,
+   drops the dangling "as described above").
+5. Updated tests to the new intent: `credits.test.js` and `tests/test_e2e_credits.py`
+   now assert the page notes footage is altered but the **CC BY-SA 4.0 declaration is
+   NOT** on credits (it moved to About).
+6. Left the `.declaration` CSS rule in `style.css` (the About page reuses these styles).
+7. Verified: node 28/28, pytest 315 passed / 2 skipped. Committed `8277417`,
+   ff-merged + pushed, removed the worktree, deleted the branch.
+
+## End state
+
+- `design/cloudflare-static-publish` @ `8277417`, clean, pushed.
+- Credits page = per-clip attributions + "footage altered" note + audio courtesy
+  block. The CC BY-SA work-license declaration (D1) is **no longer on credits** —
+  it now belongs on the About page (operator + `feat/accessibility-pass` own it).
+- Site is live; this change reaches `benstull.art` only after a **redeploy**.
+
+## Deferred decisions
+
+- **Kept a brief "footage is altered" note on the credits page** rather than
+  stripping all alteration mention. Rationale: CC BY/BY-SA attribution wants the
+  modification indicated alongside the credit; the full license declaration is what
+  moved to About. (Alternative: remove every alteration mention from credits —
+  judged worse for the per-clip attribution's "indicate changes" cue.)
+- **Left `.declaration` CSS in `style.css`** though now unused on credits — the
+  About page (other session) will reuse it; removing it would break that page.
+
+## Compliance note
+
+D1 (the altered-work CC BY-SA declaration) now depends on the About page actually
+carrying it. **Confirm it landed on about.html before considering D1 done** — it is
+currently in neither place on the live site until the About page ships + a redeploy.

+
+## Launch prompt
+
+After confirming that the "About this work" section removed in s0031 *was* the D1
+compliance (the CC BY-SA share-alike declaration, not the per-clip attribution),
+the operator: "Ok let's add that content back but can we name the section something
+other than 'About This Work' so it isn't confused with the about page?"
+
+## Arc
+
+1. Confirmed for the operator that "About this work" carried D1 specifically — the
+   ShareAlike license declaration for the BY-SA source clips — while the per-clip
+   attribution (the original goal) was untouched and stayed on credits.
+2. Claimed **session 0032**, isolated worktree off the branch tip (`8277417`).
+3. Re-added the CC BY-SA 4.0 declaration to `credits.html` under the heading
+   **"License & reuse"** (deliberately not "About this work" — that name is reserved
+   for the separate About page from `feat/accessibility-pass`). Restored the footage
+   note's "altered as described above" now that the section is back above it. Reused
+   the `.declaration` CSS left in place by s0031.
+4. Reverted the s0031 test changes: `credits.test.js` + `tests/test_e2e_credits.py`
+   now assert the declaration IS present, plus pin the rename (heading ≠ "About this
+   work", contains "License & reuse").
+5. Verified: node 28/28, pytest 315 passed / 2 skipped (e2e confirms "CC BY-SA 4.0"
+   visible in-browser again). Committed `ee7c65a`, ff-merged + pushed, removed the
+   worktree, deleted the branch.
+
+## End state
+
+- `design/cloudflare-static-publish` @ `ee7c65a`, clean, pushed.
+- Credits page now carries BOTH halves of CC compliance: per-clip CC-BY/BY-SA
+  attribution **and** the CC BY-SA 4.0 derivative declaration (under "License &
+  reuse"). The s0031 gap (live site missing the share-alike declaration) is closed.
+- Site is live; reaches `benstull.art` only after a **redeploy**.
+
+## Deferred decisions
+
+- **Section heading "License & reuse"** chosen (operator delegated the name). It pairs
+  with the "Credits & licenses" page title and is unambiguous vs. the About page.
+  (Alternatives weighed: "This work's license", "License & alteration".)

+> Status: **FINALIZED**
+
+## Launch prompt
+
+Operator asked "Have you merged to main?" → no (all work was on
+`design/cloudflare-static-publish`) → operator: "Yes" (merge it to main).
+
+## Arc
+
+1. Confirmed none of the credits work (nor the 17-commit static-publish line) was on
+   `main`; surfaced the considerations (live branch, in-flight a11y session, brings all
+   commits). Operator approved the merge.
+2. Claimed **session 0033**. Surveyed divergence: `main` and the branch had diverged —
+   `main` carried real app work from the parallel labels/affect session (per-clip
+   right-brain feelings `bf1013b`, i18n re-extract `2d54023`, affect/label fix
+   `041fcde`), not just transcript publishes.
+3. Found only **two** overlapping files (`app.js`, `altitude-lock.spec.ts`).
+   **Test-merged in a throwaway worktree** off `origin/main`: clean auto-merge, no
+   conflicts. Ran the FULL suite on the merged tree — **node 29, pytest 315/2-skip,
+   green** — before trusting the textual merge.
+4. Performed the real `--no-ff` merge on `main` in a worktree (keeping the canonical
+   checkout on the live deploy branch), pushed `main` (`75961ea`→`87d605d`).
+5. Verified credits commits + `credits.html` are on `origin/main`, branch now 0 ahead.
+   Removed the worktree; canonical checkout clean on `design/cloudflare-static-publish`.
+
+## End state
+
+- `origin/main` @ `87d605d` — now carries the entire Cloudflare static-publish line,
+  including the CC-BY/BY-SA credits page + "License & reuse" CC BY-SA declaration.
+- `design/cloudflare-static-publish` is fully integrated (0 commits ahead of main).
+- The live site still serves the pre-merge build; **a redeploy** ships the merged main.
+
+## Deferred decisions
+
+- **Merged via local `--no-ff` + push rather than a Gitea PR.** `gh` isn't wired (Gitea
+  host) and the operator approved directly in autonomous mode; the work was developed on
+  a branch and the merge produces the same merge-commit a PR would. (Alternative: open a
+  Gitea-API PR for a review record — skipped for speed; can add retroactively if wanted.)
+- **Did not merge `main` back into `design/cloudflare-static-publish`.** The branch is 0
+  ahead now; future static work can re-branch from main. Left as-is.
+
+## Next /goal
+
+```

+      <h2>For everyone</h2>
+      <p>The <em>Human Experience Filter</em> is built to be accessible to — and
+      representative of — the full range of human experience. That is why it works
+      with a keyboard, with a screen reader, with reduced motion, and away from any
+      single screen or kiosk: an experience about being human should be open to as
+      many humans as possible.</p>
+    </section>
+
+    <section>
+      <h2>Places technology let us see</h2>
+      <p>The scales you move through — the deep sea, the coast, the sky, the orbit
+      of the Earth, the wider cosmos — are vantage points no unaided human could
+      ever witness. We can share them only because our tools evolved to reach them:
+      from <strong>underwater exploration</strong>, to <strong>drones and aerial
+      imaging</strong>, to <strong>space exploration</strong>. Each scale is a place
+      a machine went first, so that a person could feel what it is like to be there.</p>
+    </section>
+
+    <section>
+      <h2>Built with LLMs</h2>
+      <p>This piece was itself built using large language models — an extension of
+      that same long arc of tools that widen what a single human can reach. The

BenStullsBets	1a6ffc74a1	feat(load): phase-1 preload gate + eligible-pick pool growth 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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-30 09:55:46 -07:00

BenStullsBets	87d605db39	Merge design/cloudflare-static-publish into main: Cloudflare static publish + CC credits 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-30 09:42:44 -07:00

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.

BenStullsBets	bf1013be74	feat(content): per-clip right-brain feelings drawn from each clip's footage 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.

BenStullsBets	041fcdeb7d	fix(sim): keep Feel (affect) words from overlapping Think (label) chips 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-30 09:06:36 -07:00

BenStullsBets	8cfceffb76	feat(content): enrich left (Think) labels to >=3/clip + motion-track abyss creatures 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.

benstull	582183db2f	Merge pull request 'fix(sim): kill the reverse-landing frame jump (D3)' (#30 ) from fix/d3-reverse-landing-jump into main	2026-06-30 14:17:56 +00:00
BenStullsBets	c13ce36787	fix(sim): kill the reverse-landing frame jump (D3) 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).
