Sigelith public proof log

A complete snapshot of the append-only proof-of-existence log of sigelith.org (formerly BeatTime proof; the same log is also served at beattime.live) up to the end of 2026-Q3: every signed checkpoint of the global Merkle tree with its OpenTimestamps proof, and every log entry of every closed week. Each version contains all earlier files, so the latest one is enough for a full audit. The log records SHA-256 fingerprints of files presented to Sigelith, never the files. A checkpoint proves that a fingerprint was presented no later than the recorded time and that the record has not changed since; it does not prove authorship or the truth of any content. Formats and verification: github.com/DeiFlagellum/sigelith-log and sigelith.org/spec/#log. The same checkpoints are published weekly as immutable GitHub releases and anchored in Bitcoin through OpenTimestamps.
