The extraction phase is complete.

Tranches 1 through 8 now preserve the substantive historical contents of
`docs/design-evolution-log.md` as exact chapter extracts.

The original monolithic log remains intact and authoritative until a separate
compatibility/routing task replaces it with an index or pointer and updates repository references.

## Refactor status

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

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

The original monolith remains authoritative pending migration.
