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.

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.
