Task 7. advance() threads the current clip as from_clip_id, plays the
server-resolved chained morphs (each already lands on its destination clip),
then locks activeClipId until the next altitude change — no fade-to-black
secondary swap, no re-roll while parked. Builds a (from->to) morph lookup
from the ring; preloads only the morphs reachable from the locked clip,
refreshed per landing (154 morphs is too many to preload up front). Drops
reverseFile + fadeThroughBlack.

Tasks 3-6. Transition is now a directed clip-pair morph; ScaleRing.morph_for
looks up (from,to)->file. advance_ring returns structural steps (no file);
resolve_move picks each crossed altitude's clip THEN its morph, chained, and
reports the locked target. Fast spin keeps the whole chain (blended) instead
of collapsing. /api/ring/advance takes from_clip_id, draws picks, returns the
resolved chain. Dropped ring_move_to_dict + _rev_file.

Tasks 1-2 of the altitude clip-pair morph plan. Manifest emits a morph
entry for every video pair in adjacent altitudes, both directions
(<src>__<dst>.mp4 zoom-in + .rev zoom-out); generate_media() bakes them
all via the existing xfade=zoomin recipe keyed by clip member.

Choose the destination clip before transitioning, play the matching
member->member morph (154 clips, all adjacent video pairs, both
directions), chain through each crossed altitude, and lock the clip
until the altitude is changed (no secondary swap, no re-roll).

The 'no sound' debugging is resolved (stale-server resilience). Move the audio
status readout + native test player into the Dev Mode panel — kept for future
'can't hear' debugging, out of the installation UI. 7 E2E pass.

The operator's video wouldn't turn on: their stale uvicorn (old Python) requires a
7-way 'content' and 422s the {visual,audio} payload, and returns {content:{video}}
not {render:{video:{shown}}}. So the alteration POST failed and video never updated
(audio works because it's client-driven). Fix: controls() also sends a back-compat
'content' field (current server ignores it; old one ignores visual/audio), and
update() reads video-shown from either response shape. Verified end-to-end against a
simulated fully-stale server: video shows + audio plays, zero errors.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Root cause of 'no sound', found via the live readout: the operator's /api/ring
returned the ring WITHOUT the per-scale audio field (a server process predating the
audio code) → soundtrackUrl() was null → the element never got a src (readyState 0,
no error). The native test player proved the file itself plays. Fix: client falls
back to a scale-id→soundtrack map (mirrors build_pool_manifest.SCALE_AUDIO) so audio
works without a server restart. Verified: stale-ring sim now plays; audio-first-then-
video leaves both on. +2 E2E regression tests (7 total). Chromium + WebKit clean.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The operator's 'PAUSED readyState 0' (no error) means soundtrackUrl() returned null
— the running app's /api/ring has no audio for the scale, the signature of a STALE
uvicorn server (Python predates the audio code; static reload doesn't restart it).
Status now shows url=<…|NONE>, ring=server|SYNTH, scale id so it's unambiguous.
Fresh server verified: ▶ playing rs=4.

Three blind fixes failed because headless browsers relax autoplay (can't reproduce)
and play() errors were swallowed. Instrument instead:
- #audio-status: live readout (playing/paused/blocked/media-error) under the toggle
- surface the play() rejection reason + element error (was .catch(()=>{}))
- 'Audio check' fieldset with a native <audio controls> on the soundtrack file, to
test the file directly with zero app code in the path
Diagnostic only — no behavior change. 37 tests pass.

Removes the tap-to-start wall (Loading Universe splash instead), fixes audio still
silent on real Safari (single <audio> played synchronously in the toggle gesture),
both toggles default off, first Video-on couples Audio. Verified Chromium + WebKit.
290 tests + 5 Playwright E2E pass.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Operator follow-ups:
- Remove the tap-to-start wall; show a 'Loading Universe…' splash until all media
preloaded (main() awaits preloadAllMedia + a progress bar), then reveal the app.
- Both Video + Audio toggles default OFF (black + silent at start).
- FIX audio still silent on real Safari: the A/B-crossfade-after-gesture didn't
unlock on Safari (priming srcless elements doesn't unlock them). Use ONE <audio>
element played SYNCHRONOUSLY inside the toggle's click — the reliable Safari
unlock; later altitude swaps reuse the unlocked element.
- First time Video turns on, also turn Audio on (one flip = full experience), set+
played in the same gesture; Audio-on-first stays audio-only.
- Soundtrack follows Altitude via the single element (brief fade swap).
- Verified in headless Chromium AND WebKit: coupling works, soundtrack plays,
video-off blanks, zero JS errors. 290 tests + 5 Playwright E2E pass.

Operator-driven revision of the audio feature: Dev-Mode-style Video/Audio toggles,
white-noise deferred (Audio = off/soundtrack), and fixes for two real-browser bugs
(video-off not blanking GPU-composited layers; no soundtrack on Safari/iOS).
Verified in headless Chromium + WebKit. 288 tests + 3 Playwright E2E pass.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Operator-driven live-UI revision:
- Video + Audio are now Dev-Mode-style on/off toggles (Audio on = soundtrack);
white-noise deferred (removed from the live control; pure machinery kept).
- FIX video-off not blanking: the <video>/<canvas> are GPU-composited and could
paint above the auto-z #black on a real GPU — give #black z-index + its own
layer AND hide the video layers (opacity 0) on video-off.
- FIX no soundtrack on Safari/iOS: Safari unlocks <audio> only when play() runs
INSIDE the user gesture; the start gesture now primes both A/B elements
synchronously, so the async crossfades are allowed to play.
- Toggles wired on 'change' (matches the Dev Mode switch).
- player/audio.py AUDIO_SOURCES -> {off, soundtrack}; tests + E2E updated.
- Verified in headless Chromium AND WebKit: audio plays, video-off blanks both
layers, zero JS errors. 288 tests + 3 Playwright E2E pass.

E2E asserts in a real headless Chromium: white_noise loads the noise asset,
soundtrack loads the current scale's asset, and Visual=off fades video while
audio keeps playing. Driving it out surfaced + fixed three client issues:
- fadeVolume uses setInterval (rAF stalls when the tab is backgrounded)
- start gesture drops srcless priming (a click grants Chrome autoplay
document-wide; priming empty <audio> only hung the handler / polluted state)
- applyAudio doesn't await play() (awaiting a srcless/buffering play can hang)

Session 0020. Anchored on the audio-video-separated-controls Solution Design.
Scope: build into the current single-page simulator (simulator-first directive);
reframe the unbuilt control-surface spec on paper. 10 tasks, all testing tiers.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Sound for the experience, plus the design to control it.
Soundtrack layer (ambience), all license-clean (PD/CC0), recorded in
docs/audio-candidate-pool.md (media gitignored; re-sourceable):
- cosmos: Pillars of Creation sonification (NASA, PD)
- orbit: station room-tone hum (CC0)
- coast: sea waves + terns (CC0)
- reef: 6-layer NOAA soundscape + CC0 submerged bed (PD + CC0)
- abyss: blue-whale moan (NOAA, PD)
Solution Design (proposed): split the bundled Content selector into two
orthogonal dials, Visual (on/off) x Audio (off/soundtrack/white-noise),
unlocking white-noise+video. Soundtrack follows the single Altitude dial;
white noise is altitude-independent. Reframes the networked-control-surface
spec SS3/SS5 (still proposed/unbuilt -> clean pre-impl edit). Music layer deferred.
Dev panel: links to the clip + audio review galleries; sticky stage/panel layout.
gitignore: audio media, review_audio.html, .DS_Store.

v1 hardware step: split the simulator into a laptop RENDERER and a separate
touch CONTROLLER over wifi/LAN. Server-authoritative SessionState + SSE push;
one /api/control contract any "control source" speaks (iPad web twin now,
Arduino later). Live knobs (Left/Right/Mood) vs transitional controls
(Altitude, Content) with per-knob transition state + renderer settled-ack.
Reframes ROADMAP sub-project 4 and absorbs sub-project 3's serial-input slice.

`make sim-local` called bare `python`, which isn't on this box's PATH (only
python3 / .venv/bin/python exist) — so it failed instantly and "couldn't connect"
to the server. Resolve PYTHON to the venv interpreter, falling back to
python3 then python.

Operator wanted more Cosmic Cliffs footage and a different-color rendering.
Keeps the NIRCam flythrough as the cosmos primary and adds ESA/Webb weic2205c
("Pan of the Carina Nebula, combined NIRCam + MIRI") as a new cosmos pool
member — the same Carina towers in the muted gray/teal/gold MIRI mid-infrared
palette, distinct from the iconic orange/blue flythrough.
- POOLS["cosmos"] grows 4 -> 5 (cosmos, cosmos_miri, galaxies, hudf, xdf);
primary unchanged.
- META + LABELS authored (nebula/star/distance, salience-gated); affect inherits
the cosmos scale vocabulary.
- manifest.json regenerated (19 -> 20 clips).
- Source: 4K master, text-free/human-free, trim 4-26s (clears the fade-from-
black), 1 s crossfade-loop (~21 s) -> 1080p base + 4K master (gitignored).
- docs/content-candidate-pool.md updated (cosmos pool of 5 + sourcing note).
271 passed, 2 skipped.

The affect channel previously gated on BOTH knobs (strength = min(left, right)),
so the analytical Left brain co-controlled the emotion words. Per operator
direction, emotions are now driven by the Right (dreamlike) knob ALONE — Left no
longer gates them. This sharpens the split: Left = measurement (detections +
measurements), Right = the dream AND the feeling it evokes.
- player/alteration.py: `_affect_strength(right) = right` (was min(left,right));
`_affect_intensity` keyed off Right. AffectOverlay + is_identity docs updated
(is_identity still holds: right>0 ⇒ dream.strength>0).
- simulator/static/app.js: renderAffect comments (gating is Right via `strength`);
the client logic already keyed min_level/tier off the passed strength + right.
- Affect design spec: revision note + every min(left,right) → right.
- Tests rewritten: affect is Right-driven (full Right + Left 0 surfaces affect;
Right 0 + Left 4 surfaces none).
271 passed, 2 skipped. Live API verified: left=0/right=4 → strength 4; left=4/
right=0 → strength 0.

Two fixes to the simulator's media handling, both surfaced by the cosmos clip swap.
1. Permanent cache-bust via content hash. New `GET /api/media-versions` returns a
short sha1 token per served file (clip bases + ring transitions + reverses),
cached by (mtime, size) so a re-bake is picked up without a restart. The client
fetches it at boot and appends `?v=<hash>` to every /media URL, so a clip
re-baked under the same path (e.g. a re-sourced cosmos base) gets a fresh URL
the browser can't serve stale — fixing the recurring stale-clip problem at the
root (supersedes the `cache: "reload"` belt-and-suspenders, which stays).
2. Fade the pool-landing swap. The baked ring transition zooms into the scale
PRIMARY, but the rotating pool picks a random member on landing — so a
non-primary pick hard-cut from the primary to the chosen clip (e.g. coast
birdrock -> surfgrass, the artifact the operator saw). On landing, when the pick
differs from the primary, mask the swap behind a short fade through the existing
#black overlay (CSS opacity transition); same-clip landings still do a plain
(re)load. General across all pooled scales.
271 passed, 2 skipped (+2: media-version content-hash + absent-file omission).
app.js syntax-checked; endpoint verified live (29 files; token matches a manual
sha1 of the bytes).

The preload fetched each clip with the default HTTP cache, so a clip re-baked
under the same path (e.g. the cosmos base re-sourced to the Webb Cosmic Cliffs
flythrough) kept showing stale footage after a reload — worst case forever, when
a pre-`no-cache` build had pinned it `immutable, max-age=1y` (a plain reload never
revalidates an immutable entry). Fetch the preload with `cache: "reload"`, which
bypasses the HTTP cache, pulls fresh bytes, and updates the cache entry; the
in-memory blob cache still gives instant in-session altitude swaps. One fetch per
(re)load, so no steady-state cost.
269 passed, 2 skipped. app.js syntax-checked.

Operator found the Orion SVS 30957 flythrough merely good and asked for a more
dramatic nebula. Replaces the cosmos-scale primary with STScI's "Exploring the
Cosmic Cliffs in 3D" (Carina Nebula, Webb NIRCam — NASA SVS 31348), sourced from
its 4K master (Clifs-3d-STScI.mp4, 3840x2160) via the content pipeline:
trim 10-34s (clears the title card ~8s and end-credit card ~102s) + crossfade-loop
-> 4K master + supersampled 1080p base (5.5 Mbps, crisper than the old 2.9 Mbps
1080p-native Orion encode).
- build_pool_manifest META: cosmos -> SVS 31348 Cosmic Cliffs, new CCBY_WEBB
credit (NASA, ESA, CSA, STScI). Labels retuned for the Carina framing
(emission nebula / protostar; redshift -> distance ~7,500 ly).
- Regenerated manifest.json (also corrects stale JPL-Orion provenance left when
129bb23 updated META but not the manifest) + all ring-edge transitions from the
new base (cosmos-orbit / abyss-cosmos now zoom from the Cosmic Cliffs).
- docs/content-candidate-pool.md: record the swap + history.
269 passed, 2 skipped. New base verified text-free + full-frame by-eye across the
loop; final look to be confirmed by the operator (no Chrome on the box).
