Methodology
How the data is derived and checked.
Everything comes from data
Pages are generated from structured data and shared templates. Assignment numbers and names can be traced to the pinned package files listed in the source table. Account-purpose explanations cite separate documentation where the assignment files do not establish a purpose. Calculators convert permission bits under the assumptions shown beside them.
What gets a page
Only numbers that are assigned in at least one indexed source package get a page. Unassigned numbers get nothing, because there is nothing to report about them.
Accounts and groups are kept apart
A name gets an account page only where it holds a user ID and has a completed description. Names that appear only as a group are covered by their group-ID page. The number pages, account pages, indexes and downloads repeat values from the same assignment matrix.
Dates
The source tables retain the original package-reading dates. New evidence checks and corrections record their own dates separately. A build does not establish a new factual verification date.
Corrections
When a figure here turns out to be wrong, it is corrected in the data and the correction is recorded rather than quietly overwritten.
Source version provenance
The Debian commit's changelog is headed 3.6.9 (UNRELEASED). The passwd.master, group.master and account documentation used here match the released base-passwd 3.6.8 files byte for byte. The 3.6.8 label identifies that validated release content, not the commit's changelog version.
