Sibling directories were seeded at byte-identical coordinates. Both gwells seeders now give each subtree an angular budget, so sibling overlap is impossible by construction.

·L-001: subdivideWedge() gives each subtree an arc weighted by leaf count — both seeders
·parallel-spines fanned in x/z, but Sigma renders (x,y) — fan moved to the spine's own plane
·L-002: coincident nodes get a deterministic FNV-1a separation angle, never Math.random()
·L-004: deleted siblingRepulsion/attractionStrength — tuned, resolved, and read by nothing
·L-005: fixed angleRad shadowing that stacked every file in a directory onto one ray
·Theme tokens for dropdowns/tile titles; fixture gate shows demo when no Tauri bridge
