V.1 — cut the CDN tether. Vendored the exact pinned files the importmap used
(three.module.js r170 + OrbitControls + CSS2DRenderer, ~1.29 MB) under
vendor/three/, mirroring the package layout so the addons' bare `import from
'three'` resolves. Import graph verified shallow (addons import only 'three';
the bundle is self-contained). Both importmaps (index.html, verify.html) now
point at ./vendor/three/… — zero jsdelivr/CDN URLs remain. MIT LICENSE +
PROVENANCE.txt retained.
V.2 — open deep time. EPOCH toggle (1800–2050 / 3000 BC–3000 AD) next to
MEGA/TRUE; deep mode is a hash-carried page mode (&e=1) read before ephem/clock
init → ephem.setExtendedRange(true) + CONFIG.time swaps to the deep bounds.
Timeline end labels + scrub tooltip now read from CONFIG (were hardcoded
1800/2050). Toggle serializes current view and reloads with the flipped e token
(orbit paths + element resolution are baked per-session). Appended 1 decade/s
and 1 century/s rates. Hash e token added to applyHash/serializeHash.
V.3 — appended verify gates (PERIHELION-V): Jupiter @1000 BC (extended 2a+2b)
vs live Horizons barycenter tol 0.15 AU (Δ 0.0041); Mercury @2500 tol 0.02 AU
(Δ 3e-5); Table 2b M-correction proven live (zeroing it worsens Jupiter@1000BC
by 0.0214 AU). Core 13 gates untouched.

- pendingCam now restores heading+pitch (inverse of serializeHash spherical),
not just distance — pasted URLs reproduce the exact view (Stage 2 gate)
- bodyWorld.sun allocated once, not per frame (§11 zero-alloc tick rule)
- spacecraft/comet label DOM writes throttled ≤5 Hz (§11); geometry still per-frame

Stage 6. almanac.js: on-focus grimoire card — physical fact sheet, hand-written
prose (grimoire voice), MODELBEAST portrait, and LIVE computed facts free from the
ephemeris: distance from Sun & Earth, sunlight age, vis-viva orbital speed, day &
year length. Earth easter egg → GODSIGH world view (:8137). Real Solar System Scope
2k textures (CC BY, 6.1 MB) now paint every world + the Milky Way skybox; ephem
gains semiMajor() for vis-viva. Generated grimoire portraits (FLUX via MODELBEAST,
10 bodies, seed logged in art/PROMPTS.md) are the AESTHETIC layer only — real
worlds get real maps (truth boundary). README with layer table + quickstart +
verify; docs/hero.jpg. Also lands the Stage-3 planets label fix (obj.visible).
Gate: every clickable body has a card; quickstart works from a fresh clone.

Stage 5. asteroids.js: 1500-strong main-belt sample from SBDB (sb-class=MBA),
propagated by the shared Kepler core, one Points cloud refreshed ≤10 Hz, off by
default. comets.js: 1P/2P/67P/96P from SBDB (elliptical only) with full drawn
orbits, marker + anti-sunward tail scaled 1/r², on by default. neos.js: CAD ±30d
close-approach radar around Earth, colored by miss distance, clickable, lunar-
distance labels, off by default. All fail-soft. verify.html gate: belt view-radii
12.1–13.9 ∈ (Mars 10.7, Jupiter 17.4); Halley aphelion 35.3 AU > Neptune. Also
serialized verify's live Horizons checks (burst-throttle fix) → 13/13 green.

Stage 4. spacecraft.js: Voyager 1/2, New Horizons, JWST, Parker, Juno, Lucy,
Psyche. Fetches VECTORS (heliocentric ecliptic AU) over a multi-year span through
serve.py's cache, Catmull-Rom interpolated per frame; glowing diamond marker +
fading trail + label with live distance from Sun and one-way light-time from
Earth. Fail-soft per craft. Robustness: sequential fetch (Horizons throttles
bursts), serve.py skips caching non-$$SOE (error) responses, and span
auto-recovery clamps START/STOP to a craft's SPK coverage from Horizons' own
"prior to / after" hints (Psyche pre-launch, Juno past coverage) → 8/8 tracked.
Gate: Voyager 1 @2026-07-15 = (-32.07,-136.21,98.55) Δ0.002 AU; JWST Δ0.011 AU
from Earth. verify.html gates 10-11 green.

Stage 3. moons.js: 21 moons as lit spheres with local per-parent compression
(clear the exaggerated parent, ordering preserved), retrograde via negative
period. rings.js: Saturn textured annulus (true 74500–140220 km scaled with
parent) + Uranus thin schematic ring, tilted with axial tilt, DoubleSide. Moons
draw at the parent's exaggeration so Io/Jupiter ≈ 0.026 ratio holds. Label
visibility gated via CSS2DObject.visible (CSS2DRenderer clobbers div.style.display
every frame — fixed). Gate: Galilean laps 1.00:0.50:0.25 (1:2:4), Triton
retrograde (Δθ<0), moons ordered io<europa<ganymede<callisto.

Stage 0. Zero-dependency serve.py (static + allowlisted horizons/sbdb/cad proxy,
sha256 disk cache with past-span immutability). Three.js via pinned importmap,
logarithmic depth, procedural starfield sky (+ Milky Way panorama swap-in), Sun
with additive glow, OrbitControls, brass-and-void HUD, scrubbable time bar,
central bodyWorld position pass, focus/camera system, hash state. Boots clean,
no console errors.
