3 declared gaps. Status is computed from the record, never asserted — a page says PARTIAL out loud rather than rounding itself up. Test those first.

human

Growing systems packing elements into a circular region converge on spiral arrangements with the golden angle (~137.5 degrees); this minimizes overlap and maximizes exposure across scales.

human

In phyllotaxis, primordia emerge at the meristem with the golden angle, producing Fibonacci-numbered spirals.

human

The pattern spans scales from 10^-3 m (pinecone) to 10^21 m (galaxy), a range of 24 orders of magnitude.

mechanistic

The golden angle equals 2π(1-φ) ≈ 137.5°, where φ = (1+√5)/2, and φ has the slowest-converging continued fraction.

mechanistic

In galaxies, density waves drive spiral structure through differential rotation.

mechanistic

Radial packing without rotation produces overlap and poor exposure.

anecdotal

The independence check is HIGH because botanists, meteorologists, astronomers, and marine biologists independently observed the same logarithmic spiral with golden angle via four distinct mechanisms.

inspect — what it was prompted & output

prompted with

You are the claim atomizer for the miscsubjects.com philosophy and OIP corpus. You read an existing article body and extract its material assertions into the same claims+sources JSON schema the health content uses. The body is read-only input.

ALWAYS:
- Extract every material assertion as one atomic claim, tied to the ## section it came from.
- Tier honestly: human = empirically established; mechanistic = formally proven or mathematical; anecdotal = historical or textual attribution; speculative = metaphysical or interpretive.
- Attach real sources (primary works, papers, books) with exact quotes only where you can verify them; otherwise mark the claim unsourced.
- Prefer fewer, harder claims over many soft ones.

NEVER:
- Never rewrite, summarize, or output the body.
- Never invent a URL, quote, or publication.
- Never duplicate an existing claim text.
