Design Evolution — Canonical Archive Index
Design Evolution is historical provenance.
It records what was believed, tested, rejected, learned, and changed over time.
It is NOT the source of current product truth.
For current product state use:
Historical material should be loaded only when a specific historical question requires it. This index enables progressive, on-demand loading of individual chapters.
Chapter Index

Structure Notes
- This index is the canonical routing entry point for Design Evolution provenance material.
- Physical archive files remain at
docs/archive/experiments/vol-1-chapters/. Their locations are verified and stable. - A later task may decide whether physical relocation is worthwhile. That decision is separate from this indexing step.
Historical Integrity
All chapter files are exact historical records. They were not rewritten, modernised, or reconciled during extraction or migration.
