The corpus is versioned on its own, apart from the API and the MCP server. v2026.12.0 is the first versioned release. The rule is one line: when a CAI or OPC decision lands, or a Law 25 checklist row changes, the corpus version changes with it.
- The scheme (vYYYY.MM.N)
- Year, two-digit month, and a release counter within the month. v2026.12.0, issued 2026-11-04, is the first versioned release; its version month and its issue month differ. From here on, the version month matches the issue month. Every change note below records its own issued date.
- Minor (v2026.13.0)
- New records, reclassifications, or new guidance attached to an existing row.
- Patch (v2026.12.1)
- Corrections, link fixes, and wording that leaves the legal substance untouched.
- The one-line rule
- A changed CAI/OPC decision or Law 25 checklist row bumps at least the minor segment. Nothing is edited silently; retired records stay in the corpus.
- Breaking renames
- Ship as a new major train (v2027.01.0), never as an in-place edit of an existing record.
