Archive

Append-only, out-of-context prune sinks for Yggdrasil's accumulating lists. When a hygiene step retires an item it appends here rather than deleting it — a readable, browsable record (vs. git-diff archaeology). Never pruned, reviewed, or nagged.

One file per source kind:

• bookmarks.md — retired entries from bookmarks.md (and cold items from backburner.md, which is bookmark-lineage and drains here).
• session-lessons.md — retired entries from the ## Session lessons list.
• done-log.md — aged-out granular bullets drained from the ### Done log.
• catalog.md — superseded entries from the ## Design decisions catalog.

Non-canonical archives (added per the convention as the hygiene pass drains other sources):

• hygiene.md — resolved consistency-check (drift) runs drained from working/hygiene.md.

Further archive files may appear here over time — each carries the same standard header and adds its own line to this index.
