# Design Evolution Archive — Tranche 1

This directory contains exact historical extracts from
`docs/design-evolution-log.md`.

The original monolithic log remains intact and authoritative while the archive refactor is in progress.

These files are historical provenance, not current product truth.

For current product state use:
- docs/current-handoff.md
- docs/current-project-state.md

## Refactor status

Only tranche 1 has been extracted.

Do not remove these ranges from `docs/design-evolution-log.md` yet.

Do not update repository-wide references to point here yet.

Further Design Evolution material must be extracted in separate bounded tranches and verified before the original monolith is replaced by a compatibility/index document.
