The family historian

# Part 13 — The Family Historian

The **Family Historian** at **`/historian/[projectId]`** is a conversational surface where you can ask about the life captured in the project and get bilingual, historically aware responses.

## 13.1 What the historian can do

Five surfaces are accessible from the historian sub‑nav:

| URL | Surface |
|---|---|
| `/historian/[projectId]` | Overview |
| `/historian/[projectId]/chat` | **💬 Chat** — ask any question |
| `/historian/[projectId]/expansion` | **🔍 Life insight** / **🧵 Cross‑project synthesis** |
| `/historian/[projectId]/memory` | **🌿 Memory expansion** |
| `/historian/[projectId]/chapter` | **📖 Chapter expansion** |

## 13.2 The chat surface

The chat has:

- An **EN / FR toggle** in the top‑right
- A **message board** showing your questions and the historian's replies as bubbles
- A **composer** at the bottom (Cmd/Ctrl+Enter sends)

When you ask a question, the historian responds with a **simulated streaming** reply (the bubble fills in word by word). Each reply may include **reference chips** — small badges showing which materials it drew from (memories, chapters, timeline, media, capsules).

The thread is **stored independently for EN and FR**. Toggling the language switches threads.

## 13.3 Expansions

The four expansion kinds (memory / chapter / insight / synthesis) work like the Memorial AI:

1. Click **✦ Generate**
2. Fill in the form (person name, relationship, family name, optional locations / relationships / milestones / qualities / memories / notes — and a memory or chapter ID for those kinds)
3. The platform produces a bilingual draft
4. Edit in the **EN / FR tabbed editor** below
5. Save to the vault, attach to a chapter, attach to the timeline, attach to a capsule, mark published — same buttons as the Memorial AI editor

## 13.4 Revision workflow

Every editor has a **✦ Request revision** button. Instructions go in a text box; a checkbox lets you **Regenerate from scratch** instead of revising. Revisions are saved in a per‑output history.

## 13.5 Activity log

A **Historian activity** log at the bottom of every page tracks chat questions, generated expansions, edits, saves, attachments, and publishes — each tagged with language. You can clear it anytime.
