Content candidate pool — operator-selected, vetted (2026-06-24)

The 5 scales each get a rotating pool of clips. When the viewer lands on a scale by zooming the ring in/out, the player randomly picks one clip from that scale's pool. (This supersedes the one-clip-per-scale model — see docs/superpowers/specs/2026-06-24-content-pipeline-design.md.)

Every clip below was operator-selected from the candidate gallery, is strict public-domain or CC‑BY‑class with attribution, and was vetted word‑free / human‑free (windows trimmed past title cards, captions, telemetry burn‑in, divers, construction, logos). All processed via tools/pipeline/run.py process_clip (trim → crossfade‑loop → 1080p proxy). Media is gitignored; this file is the re‑sourceable record. Sim ids are the simulator/sample_media/<id>/ dirs.

License rule confirmed by operator: CC0 / CC‑BY / CC‑BY‑SA are acceptable with a credit line (our overlays + dream are derivatives, which these allow); CC‑BY‑ND is NOT usable (no derivatives); CC‑BY‑NC only if the installation stays non‑commercial.

🌌 cosmos (pool of 4)

cosmos	Orion Nebula flythrough	NASA/JPL‑Caltech — https://images.nasa.gov/details/JPL-20221122-SOLSYSf-0001-Orion%20Dust%20and%20Death	~30–54	PD (17 U.S.C. §105)

⚠️ DISCREPANCY to fix next session. Operator selected cosmos #1, #3 (Orion), #4, #5. During processing, #6 Galaxy Traverse was run by mistake instead of #3 Orion. The Orion clip (#3) is text‑free and already lives at simulator/sample_media/cosmos/base.mp4 (the prior real base), so the pool above is correct. cosmos_traverse is an UNSELECTED extra on disk — drop it (or confirm with operator). The current ring scale id is cosmos; when the pool is wired, cosmos becomes one pool member.

🛰️ orbit (pool of 3)

id	clip	source	window (s)	license
orbit_planetearth	ISS — View of Planet Earth	NASA SVS — https://svs.gsfc.nasa.gov/vis/a030000/a030700/a030771/ISS_View_of_Planet_Earth_2160p.mp4	10–34	PD
orbit_crewobs	ISS — Crew Earth Observations	NASA SVS — https://svs.gsfc.nasa.gov/vis/a030000/a030700/a030771/ISS_Crew_Earth_Observations_2160p.mp4	9–33	PD
orbit_bluemarble	NPP "Blue Marble" rotating globe (CG)	NASA SVS — https://svs.gsfc.nasa.gov/vis/a000000/a004500/a004550/BlueMarble_starfield_4k_2160p30_v2.mp4	10–34	PD

Operator also selected aurora→Perth (#4) and west‑coast lights (#5); both rejected as UNUSABLE — #4 has a date/time burned into every frame, #5 has the ISS module + solar panel in frame throughout. No clean window exists in either.

🏖️ coast (pool of 4) — NEW scale, replaces the granite/waterfall forest

id	clip	source	window (s)	license
coast_birdrock	Bird rock + ocean (aerial)	NPS Channel Islands — https://www.nps.gov/nps-audiovideo/audiovideo/663a2f13-6183-4b3e-a4a9-6698a84619d01080p.mp4	3–27	PD
coast_surfgrass	Surfgrass / coralline tidepool	NPS Cabrillo — https://www.nps.gov/nps-audiovideo/audiovideo/de7d1cf2-e422-45b5-aa66-4c69e29a4d811080p.mp4	2–26	PD
coast_elkbeach	Elk resting in coastal grass/fog	NPS Redwood — https://www.nps.gov/nps-audiovideo/legacy/redw/4634070E-F68D-4F74-E43174448168AC8A/redw-elkbeach_1280x720.mp4	20–38	PD (720p source)
coast_drakesbeach	Elephant seals on dark sand	NPS Point Reyes — https://www.nps.gov/nps-audiovideo/audiovideo/1cfd8165-1061-4d75-af53-b46c2e3ed2701080p.mp4	20–35	PD

Operator also selected the Lifeboat Station "elephant seal timelapse" (more‑options #3) — FAILED: the NPS page's video resolved to the wrong footage (an aerial of the bay with road/parking/boats, no seals). An alternate source UUID (50a7a20a-9e52-4643-b186-c61ce1cef0f7) appeared in the page HTML and could be retried next session if the seal timelapse is still wanted.

Scale rename: the live ring scale is still forest (Yosemite). Next session renames it coast and points it at this pool. The old real Yosemite base (simulator/sample_media/forest/) becomes unused.

🐠 reef (pool of 5)

All NOAA Fisheries b‑roll (PD, credit "NOAA Fisheries"); Brightcove download endpoint https://download.gallery.brightcove.com/api/gallery/account/659677166001/site/site-600408/video/<VIDEO_ID>/download.

🦑 abyss (pool of 3)

All NOAA Ocean Exploration (PD, 17 U.S.C. §105). These have creatures drifting into and out of frame — the prime material for time‑windowed tracked labels.

id	clip	source	window (s)	creatures
abyss_wow	"World of Water"	https://oceanexplorer.noaa.gov/wp-content/uploads/2018/05/wow-1280x720-1.mp4	10–34	jelly + ctenophore + siphonophore enter/exit
abyss_midwaterexp	"Midwater Exploration"	https://oceanexplorer.noaa.gov/wp-content/uploads/2019/09/midwater-exploration-1920x1080-1.mp4	16–40	white medusa + red worm enter/exit
abyss_hiding	"Hiding in the Dark"	https://oceanexplorer.noaa.gov/wp-content/uploads/2018/05/dark-1280x720-1.mp4	20–44	crimson jelly + ctenophore enter/exit

Operator also selected Crossota (#4) and comb jelly (#5); both rejected — Crossota has only ~17s clean (too short for a 24s window), comb jelly has a species caption covering the whole clip.

On disk but NOT in any pool (clean up next session)

• cosmos_traverse — unselected (the #6/#3 mix‑up above).
• orbit_westcoast — rejected (ISS hardware in frame); leftover output dir.
• forest — the old Yosemite base, superseded by the coast pool.
• reef — the original placeholder/early reef base, superseded by the reef_* pool.
• The review.html gallery + all cosmos/orbit/coast/reef/abyss candidate dirs are local‑only (gitignored).
