Methodology v0.1

A preregistration scaffold for repeatable research observations and the calculation contract behind the browser-local Lab. The provider-collection protocol is not frozen and no provider collection has started. A dated synthetic example makes the current local calculation contract reproducible.

1. 01

   Observation unit

   One user-supplied public answer, its visible cited or linked sources, the public surface and configuration, locale, and timestamp.

   #
2. 02

   Sampling frame

   Question classes and a stable control set must be fixed before provider collection starts.

   #
3. 03

   Measures

   Visible source-domain recurrence, mean pairwise token Jaccard overlap, literal phrase coverage, and missingness—with explicit denominators and limitations.

   #
4. 04

   Comparability breaks

   Prompt, route, model, interface, policy, locale, or sampling changes must create a new series or a visible annotation.

   #
5. 05

   Redistribution

   Only material permitted by provider terms and applicable rights may be retained or published.

   #
6. 06

   Corrections

   Every correction records a version, affected records, reason, reviewer status, and effect on comparability.
