The canon as anchor
Every distortion measure needs an anchor. That anchor is not metaphysical truth; it is the public reference the institution stands behind: name, role, limits, versions, exclusions, and source hierarchy.
Without a declared canon, every dispute about an output turns into a conflict of perceptions. With a canon, the question changes: what dimension did the output move away from, and how?
The kinds of gap that matter
Not every deviation is the same. Some add an unproven attribute. Others shift temporality, invert a negation, merge two roles, or expand scope without declared support.
Naming those forms of deviation helps move away from binary true/false thinking and toward governance: where did the output drift, and what follows from that drift?
- addition without evidence
- omission of an exception or condition
- inversion of a negation
- generalisation of a local or time-bound case
Why debating truth is a trap
In a multi-source environment, everyone can point to some plausible fragment. The truth debate becomes endless, especially when the ecosystem contains stale versions, third-party paraphrases, and status conflicts.
Distortion measurement does not settle every controversy, but it makes controversy governable: it localises the displacement and enables targeted correction.
What public trace is enough
An institution does not need to publish a formula. It can publish the dimensions it treats as critical: canonical status, temporality, priority sources, exclusions, and assertion levels.
That publication is what later makes it possible to talk about canon-to-output gaps without turning doctrine into detailed instrumentation.

- Drift index — The temporal complement: track variance instead of reading only a snapshot.
- Assertion levels — Distinguish fact, inference, hypothesis, and opinion in governed output.
