# 02 — Roadmap & Phases

Iterative build-out, value-first. Each phase is shippable on its own.

## Phase 1 — The Spine (connectivity)

**Focus:** datapath between Memos, n8n and SAIA.
**Milestone:** Nexa replies on Memos and answers simple questions.

- [ ] **1.1 Memos ↔ n8n bridge** — webhook ingress, content filter, comment-back.
- [ ] **1.2 SAIA integration** — call LiteLLM proxy from n8n; chat via Memos comments.
- [ ] **1.3 Git-sync** — periodic export of n8n workflows into this repo.

## Phase 2 — Senses (input channels)

**Focus:** e-mail filter and the Work-vs-Personal router.
**Milestone:** Nexa distinguishes work tasks from personal tasks without manual tags.

- [ ] **2.1 Email butler** — filter & summarize the ~20 daily personal mails.
- [ ] **2.2 RSS morning digest** — curated daily summary in Memos.
- [ ] **2.3 Bluesky antenna** — store liked posts as knowledge snippets.

## Phase 3 — Memory (Qdrant & RAG)

**Focus:** Qdrant + (optional) graph DB for retrieval-augmented answers.
**Milestone:** RAG works — Nexa answers from archived notes.

- [ ] **3.1 Embedding pipeline** — automatic vectorization of Memos & Obsidian.

- [ ] **3.3 S3 long-term archive** — Qdrant snapshots to the S3 server.
- [ ] **3.4 Graph layer (deferred decision — see [11-open-questions](./11-open-questions.md))** — Neo4j *or* Ontotext GraphDB for structural queries.

## Phase 4 — Motor (organization & action)

**Focus:** calendar integration and time-boxing.
**Milestone:** Nexa proactively proposes morning focus slots in the work calendar.

- [ ] **4.3 Karakeep curation** — automated review cycle for saved links.

## Phase 5 — Daily integration (polish)
