Record completeness checklist
1
Anchor canonical hash to Bitcoin via OpenTimestamps
open
Stamps the canonical SHA-256 (
5d02af7aed644381f9064c04...) across
three calendars. Confirms instantly. Calendars upgrade to a Bitcoin-block proof in a few hours.
2
Mirror to Internet Archive (Wayback Machine)
open
Submits the paper URL to the Internet Archive and records the resulting Wayback capture
URL plus timestamp. Pith does not host the paper.
4
Sign a citation pointing at this record
open
Records a signed citation. Pick a relationship (supports, refutes, extends, uses_method,
depends_on, replaces, compares, cites). Pith signs the assertion server-side.
5
Submit replication, falsification, or formal bridge
open
Public record of a replication attempt, formal bridge (Lean / Coq), or falsification.
Held for moderation. Not peer review; a typed annotation.

Verify this Pith Number yourself
Three shell lines recompute the canonical hash. If the hash you compute matches the one shown above, the record is intact end-to-end.
