Multi-agent adversarial review (verified findings) — the top finding (dead orbit
drag) fable had already fixed in 3e36a0c; these are the rest, composing on top of
fable's 228caf2/3e36a0c:
- scale.js viewFromEcl: allocation-free + alias-safe (read x/y/z into locals before
writing out) — it ran per body per frame and allocated an object each call (§11).
- planets.js + comets.js: refill orbit paths on any P change, not just
isTransitioning() — the MEGA↔TRUE tween's FINAL frame (P settled, tween nulled)
was skipped, leaving body/orbit desync (§12).
- almanac.js: a moon's heliocentric position adds its true orbital offset, so the
Moon's "From Earth" is its real ~384,400 km / 1.3 s light, not 0.
- asteroids.js: guard refresh() against null geometry when toggled on before the
SBDB load completes (was a TypeError).
- serve.py: CAD close-approach responses are never cached immutable — the database
keeps growing for past dates as new NEOs are discovered (only Horizons ephemeris
is truly immutable).
Re-verified: 13/13 gates green; orbit zoom dollies 82→73 finite; Moon From Earth
0.003 AU; layer toggles throw nothing; no console errors.

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 1. ephem.js: JPL SSD approximate elements (Table 1 + 2a/2b plumbing),
Newton Kepler solver, reusable eclFromElements core (planets + small bodies),
orbitPath sampler. planets.js: 8 planets + Pluto as textured exaggerated spheres
on MEGA-compressed orbits with labels, rebuild-on-drift. verify.html: 9 gates all
green IN BROWSER incl. live Horizons via proxy — Mars @2026-07-15 Δ3.3e-4 AU,
Jupiter Δ2.9e-3, Earth Δ3.9e-5; Mars @J2000 vs live Δ4.8e-5; Jupiter @1900 Δ2.0e-3.
