Stanford Encyclopedia of Philosophy: every entry has permanent dated archived editions

Claim: The Stanford Encyclopedia of Philosophy maintains permanent dated "archived editions" of every entry so scholars can cite a specific snapshot in time.

Confidence: Verified (primary).

Why this matters as a model: Most CMS-backed marketing sites overwrite history on every edit. A KB-backed site can preserve dated versions — either via git history surfaced as URLs, via Docusaurus-style version snapshots, or via a dateModified + change log per entry. The Stanford pattern is the strongest example of citation-grade content discipline.

This KB's posture: the schema captures created_at, updated_at, and per-update history via trigger (audit table). Slug renames preserve old aliases. Soft-delete only. The infrastructure for SEP-style citation discipline is already in place; what's needed is the editorial habit.
