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 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.
