Silent revision is the quiet failure of digital publishing. A deterministic pipeline gives every dispute a floor: the same bytes, the same hash, on every machine, forever.
Every published text now travels through a dozen hands and programs before a reader sees it. Somewhere on that path a sentence changes, and nobody can say when. When a dispute arrives, the only evidence is a screenshot and a memory.
LPS-1 answers this with a procedure, not a promise. The work is canonicalised so that line endings, invisible marks and file order cannot change its fingerprint. Every file is hashed with SHA-256. The hashes are organised into Merkle trees by content type, and the four roots are combined into one edition root. That root is written to a public chain with a block timestamp and cross-stamped to Bitcoin through OpenTimestamps.
The word that matters is deterministic. Two honest people on two different computers must get the same root from the same files, or the whole idea collapses into argument. The reference implementation ships the normalisation rules and the tests that prove them, and this site reads the anchored roots straight from the chain so you can compare.
What it does not do is just as important. It does not decide who owns a work; it proves who anchored it first and that it has not changed since. It does not keep a file available; it makes any copy checkable. It does not stop copying; it makes plagiarism provable.
