# Design Archive

This directory contains historical `sw-block` design/planning documents that are still worth keeping as references, but are no longer the main entrypoints for current work.

Use `sw-block/design/` for active design and process documents.
Use `sw-block/.private/phase/` for current phase contracts, logs, and slice-level execution packages.

## Archived Here

- `v2-production-roadmap.md`
- `v2-engine-readiness-review.md`
- `v2-engine-slicing-plan.md`
- `v2-prototype-roadmap-and-gates.md`
- `phase-07-service-slice-plan.md`
- `phase-08-engine-skeleton-map.md`
- `v2-first-slice-session-ownership.md`
- `v2-first-slice-sender-ownership.md`
- `a5-a8-traceability.md`

## Why Archived

These documents are useful for:

1. historical decision context
2. earlier slice/phase rationale
3. traceability for passed reviews and planning gates

They are not the canonical source for the current phase roadmap.
