Five methods and six statutes, frozen. Wire format and canonical serialisation are stable; anything that changes them is a major version.
Versions
What changed, and when
TIP is versioned. A record states the version it was sealed under, and that version's rules do not move afterwards.
Changelog
The specification14 August 2026 · TIP/0.9
Epoch anchoring, second rail
Roots commit to a qualified timestamp; a second rail, a public chain, is specified beside it. Once both are live a record survives either failing. The register states which is.

CDRP reconstructs what the system would have concluded at a past moment from the evidence held then, not from what is known now.
9 May 2026 · TIP/0.7
Supersession without erasure
A superseded record stays readable and stays verifiable, linked to the record that replaced it. History became append-only here.
Build against a version that stops moving
A record states the version it was sealed under, and that version's rules do not change afterwards.
