+- Repositioned Deja Vu as a protocol-first memory system for AI agents.
+- Rewrote the root README around rules, workflow, and Markdown memory as the primary adoption path.
+- Added the core protocol references:
+  - `docs/protocol.md`
+  - `docs/workflow.md`
+  - `docs/storage-markdown.md`
+- Added copyable project rules and memory templates under `docs/templates/`.
+- Added `examples/protocol-project/` as a repo-first example that works without npm or the optional engine.
+- Moved the semantic TypeScript engine into an explicitly optional documentation path under `docs/engine/`.
+- Rewrote handshake, bootstrap, release, and AI-readable docs to match the new protocol-first framing.
+- Updated package metadata to describe the npm package as an optional semantic recall layer.
+- Fixed `npm run test:src` for the current Node.js v24 environment by switching to a compatible `ts-node` registration path.
