Designed (brainstorm → spec), built TDD-first, shipped to +`main`, then **revised the scale after operator eyeball**: the initial −2×…2× +range with a manual reverse loop jittered in a real browser (base loop clips +aren't all-intra), so it was narrowed to **0×–4× forward** and the reverse +machinery removed. + +### Arc + +1. **Brainstorm** (no tracked init this session — claimed s0038 at finalize). + Surfaced the real tradeoff: "Reduce motion" is the a11y safety control + (`isReduced()`), doing three things beyond freezing the loop (OS-pref default, + instant transitions, photosensitivity floor). Two operator decisions via + AskUserQuestion: **keep a11y but move it** (derive from OS + `prefers-reduced-motion`, no visible toggle) and **implement a true manual + reverse loop** for the negative range. +2. **Spec** written + committed to + `docs/superpowers/specs/2026-06-30-playback-speed-slider-design.md`. +3. **Build (round 1, −2…2 + reverse), TDD:** worked in worktree + `feat/playback-speed-slider` (off `origin/main`). Pure node-tested + `HEFScrub.reverseStep` helper (RED→GREEN); slider + datalist in `index.html`; + `applyPlaySpeed` + rAF reverse loop in `app.js`; `isReduced()` re-derived from + OS pref; retired `hef.reduceMotion`; i18n `speed.label` + reworded `warn.body`. + Verified 14/14 node unit, 13/13 a11y e2e (Task 5 rewritten), static-build e2e + 2/2 (built the dist bundle to confirm). Merged to `main` (`df8b245`) — + concurrent session pushed mid-merge, so rebased onto the new tip and pushed. +4. **Operator eyeball:** reverse was jittery; operator chose **0×–4×** as the + scale. +5. **Build (round 2, 0×–4× forward):** worktree `feat/speed-forward-0-4x`. + Removed the reverse rAF loop + `reverseStep` helper + its 4 unit tests; + slider `min=0 max=4`; datalist ticks at 0.5; spec annotated with a revision + note. Verified 10/10 node unit, 12/12 a11y e2e (against the actually-served + worktree code). Merged to `main` (`e064a2e`, clean FF) and pushed. +6. Served the merged code locally at `http://localhost:8099/` for re-view both + rounds. + +### Pipeline (§9) + +This app is **exempt** from flotilla/PPE/§9 prod gate — public target is static +Cloudflare (Pages + R2). Change is merged to `main`; **operator redeploy** of the +static build is the remaining ship step. E2E browser tests (Playwright) were run +locally and are green. No plan artifact archived: design lived in the spec +(already in this repo's `specs/`, merged); app has no `content` repo. + +### Next session + +Operator by-eye review of the 0×–4× speed feel on the live sim, then redeploy to +Cloudflare to publish it. + +## Launch prompt + +> Let's add a "Playback Speed" slider that goes from -2x (which would play +> backwards) to 2x, with increments of 0.25. This only applies to the altitude +> videos, not the morph videos. This can replace the "Reduce motion" toggle + +_(Mid-session the operator refined: continuous drag rather than 0.25 detents; +then, after eyeballing reverse jitter, narrowed the scale to 0×–4× forward.)_ + +## Plan + +> Anchor: leaf `feature`/`task` (UI control on an existing surface). Design → +> spec → TDD build → ship branch → PR/merge → operator redeploy. + +Continuous Playback Speed slider driving ONLY the resting altitude loop video +(`#vid-loop`); morph/transition video (`#vid`) is scrub-driven and untouched. +Reduced-motion accessibility preserved but derived silently from OS +`prefers-reduced-motion` (slider disabled when active). Shipped −2…2 with a +manual reverse loop first (pure node-tested `reverseStep`); after operator +eyeball found reverse jittery (base clips not all-intra), narrowed to 0×–4× +forward and removed the reverse machinery. Verification: node unit + Playwright +a11y e2e + static-build e2e, all green per round. Project exempt from §9/PPE +(static Cloudflare). + +## Deferred decisions + +- **Direct FF-merge to `main` (no PR).** Operator explicitly said "Merge to + main," so both rounds landed via fast-forward (round 1 rebased over a + concurrent push) rather than opening a Gitea PR. Alternative: branch → PR → + merge (§5.4 norm). Operator-directed, so low risk. +- **Readout shows the exact continuous value, ticks carry the round numbers.** + The slider value is shown as e.g. `1.37×`; the "nice" increments (0.5 marks) + live as `` ticks rather than snapping the value. My call within the + approved design; operator approved the spec. +- **Datalist tick spacing 0.5 over 0–4** (vs 0.25 over −2…2 in round 1). Cosmetic + choice to avoid clutter on the wider forward range. My call. +- **Reverse fully removed, not kept as a smaller range.** Operator said "just go + 0x - 4x as the scale," so the `reverseStep` helper + tests were deleted rather + than parked. If reverse is wanted later, re-encode base loop clips all-intra + first (noted in memory + spec revision). diff --git a/sessions/0038/SESSION-0038.0-TRANSCRIPT-2026-06-30T12-25--INPROGRESS.md b/sessions/0038/SESSION-0038.0-TRANSCRIPT-2026-06-30T12-25--INPROGRESS.md deleted file mode 100644 index 48ccc8a..0000000 --- a/sessions/0038/SESSION-0038.0-TRANSCRIPT-2026-06-30T12-25--INPROGRESS.md +++ /dev/null @@ -1,23 +0,0 @@ -# Session 0038.0 — Transcript - -> App: human-experience-filter-art -> Start: 2026-06-30T12-25 (PST) -> Type: planning-and-executing -> Posture: yolo -> Claude-Session: 52b811fa-0926-4619-ae31-3c71d489c686 -> Checkout: /Users/benstull/git/benstull.org/benstull/human-experience-filter-art -> Status: **PLACEHOLDER — claimed at session start; finalized at session end.** -> -> This file reserves session ID 0038 for human-experience-filter-art.
