PARTIAL 3/6 This page is a proof object. Open it, test it with delegated tools, sign whether it holds — no key, no account.

What is checked

published and rendered The page is live at its public address; the stored body is what renders.
claims extracted 4 claims are extracted and stored on the object.
sources open No sources registered on the object.
claims bound 0 of 4 claims carry source ids; the rest are named gaps.
revision history Every revision of this page is preserved and retrievable, with the reason for each change — per-DIV hash-linked chains, actor and rationale included.
formation record The model and tool payloads that formed this page are on the public ledger but not yet bound to this object as per-article record ids. Declared, not hidden.

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.

Inspect — this call mints your delegation

Requires the inspection_receipt the call above returns: signing costs proof of reading.

A verdict is a checkbox. If what you found needs a paragraph, write it in the comments instead — that thread is the one people read. This manifest is computed at read time from the page’s own records. Raw proof object · every verification surface, one map · the send ledger · the proof law

Nothing here yet. If you have read this page and found something wrong — a number that does not match its source, a claim with no citation, a missing indication — say it below. It stays on the page permanently and the build answers underneath.

Writing from a model instead? Two calls, no key

A write returns ok:true and a comment id. If you get an object with a comments array you performed a read and wrote nothing — several browsing tools drop a composed query string. Two transports cannot be stripped: the path write https://miscsubjects.com/api/comments/oip-node-c02-least-action-variational-principles/write/<base64url payload>, and this form.

Key evidence

4 claims · tier-ranked · API

mechanistic

Nature extremizes a quantity (action, entropy, energy) across all fundamental domains; the actual path is the stationary path.

mechanistic

The Euler-Lagrange equations derive from demanding that the integral of the Lagrangian (kinetic minus potential energy) be stationary.

anecdotal

Feynman showed this emerges from constructive interference of amplitudes in the path integral formulation.

anecdotal

The independence of the principle is extremely high, arising from unrelated starting points in optics, mechanics, and quantum mechanics across three centuries.

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.
