Changelog and version index

Every assessment names the version it was performed under. A level means nothing without one, so every change to this rubric is dated, numbered and classified.

Clarifying changes cover wording, examples, added evidence guidance, and corrections that could not move any system's score. The test is strict: if an unchanged system could be scored differently before and after the change, it is not clarifying. Breaking changes cover anything that could move a score for an unchanged system — a changed level descriptor, a changed evidence requirement, a changed depth cap, a change to what a dimension covers, or a change to a threshold.

A score awarded under an earlier version stays awarded under that version. We do not restate historical scores against a new version. Where a breaking change would move a score, the entry says so, and the only way to hold a level under the new version is a new engagement.

• 2026-09-19 · v1.0 · initial publication

  First published version of the Ordoia Assurance Levels: eight dimensions in four pairs, four levels, the depth grid, and the reporting rules. No prior version exists, so no system's score can move. Permanent address ordoia.com/oal/v1.0.

One entry is not an empty changelog. It is dated, and it establishes the address at which this version will remain after it is superseded.

Version index

Superseded versions stay published at their own addresses indefinitely, so that a scorecard issued under an earlier version can still be read against the criteria it was awarded under.
