Sends approved drafts back + out via SMTP. It *can* talk for its own configuration (the bind-on-invite + question, account setup) like any bot; the invariant is not silence, it is + **credential isolation**: it is the only component that touches the mail + server. Day to day the family interacts with the archivist, not it. +- **archivist** (no mail creds, bot-runner): sees the posted message, + classifies, folds it into its thread file, files to the vault, emits + `dev.famstack.event`. Identical to what it already does for a pasted URL or + note. Email adds no new pipeline; it adds one recognized message shape. + +The Matrix room is the handoff, the durable source of record, and the +family-visible surface at once. This **drops the shared-Maildir volume** the +earlier draft used: no shared filesystem, no IMAP-reading code in the +archivist, and the email arrives as a first-class room message instead of a +silent file plus a separate notification. `stack mail …` wraps `docker exec` +into the gateway for send and status. + +### Email thread maps to a Matrix thread + +postmoogle (the reference bridge) folds an email thread onto a native Matrix +thread and exposes three switches worth mirroring: `threadify` (the message +body lives in the thread, not the room timeline), `nothreads` (off switch), +and `stripify` (drop quotes + signatures, their reply-parser). We do the same: + +- One **root message per conversation** sits in the room timeline (subject + + sender + briefing). The room stays one line per thread, not N. +- Each later message is a **threaded reply** (`m.thread`, keyed by + `thread_root`). The thread holds the conversation; the timeline stays calm. + Flood solved, the way the reference implementation solved it. +- The archivist reads the `m.thread` relation to know which vault thread file + the message folds into, reusing the fold already shipped. + +### Every ingested message is twofold + +A message the archivist ingests carries two faces on one event: the rendered +view the family reads, and the raw original the machine re-derives from. The +gateway is the first producer of this shape; every ingest source should adopt +it. + + m.room.message { + msgtype: "m.text", + body: "", + "dev.famstack.source": { + source: "email", // email | note | url | scan | ... + raw_content: "", + // source-specific descriptors: + from: "office@springfield-school.example", + message_id: "", + thread_root: "", + captured_at: "2026-06-21" + } + } + +- `body` is the nice view: always present, always derived from the original. +- `raw_content` is the **reproducibility anchor**. Re-folding and reprocessing + read it, never re-fetch IMAP (ADR-010). Naming the field closes the + reproducibility gap from the threading section: today `reprocess` re-feeds + the model its own prior summary, which is lossy; with `raw_content` it + re-reads the real source. +- the source block lets each inbound type add its own descriptors (email: + from / message_id / thread_root; a future scanner: device / page count) + with no schema change. + +Classification still produces the existing `dev.famstack.event` filing +envelope (`{source, type, summary, data}`). `dev.famstack.source` is the raw +input that envelope is derived from, not a replacement for it. + +### Plumbing lives in the bot framework (MicroBot) + +None of the above is email-specific code. Posting a twofold message, +threading it under an `m.thread` root, stamping `dev.famstack.source` with +`raw_content` + per-source fields, and recognizing such a message on the way +in are all **framework concerns**, not bot concerns. They belong in `MicroBot` +(`stacklets/core/bot-runner/microbot.py`), whose `_send(metadata=…)` already +carries custom keys onto the visible message. The mail bot and the archivist +are both `MicroBot` subclasses; the gateway calls a framework helper to *post* +a source event, the archivist a framework hook to *consume* one. A future +ingest source (a scanner, a webhook) subclasses the same framework and gets +the twofold shape for free.

So the mail bot posts each attachment into the room as a normal +Matrix media event (`m.file` / `m.image`) in the **same thread** as the text. +"The whole message" is then the text event plus its sibling media events, +co-located under one `m.thread`. + +The win: attachments ride a path the archivist **already has**. `_on_file` +(`archivist.py`) routes `m.file` / `m.image` uploads through the +DocumentPipeline and `capture_binary` today, so an emailed PDF (a school form, +an invoice) lands in Paperless exactly as a dragged-in file would, and an image +lands in the vault. No new attachment code. The email thread file and the +resulting document correlate by living in the same Matrix thread. + +One real concern to settle when we build this, not now: **not every attachment +is signal.** Sender-signature logos, inline tracking pixels, and tiny images +would flood Paperless and the room with junk. The bot needs an attachment +filter (skip below a size threshold / inline-disposition images), and an +on/off toggle, the way postmoogle exposes one. Body text is unaffected; this +is purely about which binaries get pasted. + +## Routing email into Matrix rooms + +Family email should *appear in Matrix* — in the room the family chose for it — +not just file silently into the vault. famstack already has the exact +mechanism: topic rooms bind a room to intent via a **`dev.famstack.capture`** +room-state event carrying a `kind`, and the bot welcomes itself + bootstraps on +join (`topic_rooms.make_room_state`, `archivist._send_room_welcome_if_needed`). +The state schema already anticipates kinds beyond `topic` (the documents-room +binding, "future" kinds). Email is one more kind on the same rails. + +**The binding is room state, set by the bot — not static `stack.toml`.** This +matches the topic-rooms pattern and the self-explaining-UX rule (bots configure +on invite, not via a config file the family never sees).

If unbound, it asks the one question it needs: *which account and folder + route here?* (e.g. `family@… / INBOX`, or `family@… / Schule`). Answered by + a short reply or a `bind ` command. +4. The bot writes the room-state binding. From then on, mail in that + (account, folder) posts to that room. + +One account's folders can fan out to different rooms (INBOX → `#Post`, a +"Schule" label → `#Schule`); the binding is per-room, so it composes. + +### How a message reaches the room + +The **gateway** fetches IMAP, resolves the `(account, folder)` to a bound room +via the `dev.famstack.capture` binding, and posts the message there: a rendered +`body` plus the `dev.famstack.source` block (`raw_content`, `from`, +`message_id`, `thread_root`), threaded under the conversation's root. That post +*is* the source of record. The **archivist** then does what it does for any +room message: classify, fold into the vault thread file, and emit +`dev.famstack.event` back onto the timeline. The gateway routes (it knows the +binding and holds the creds); the archivist files (it holds no creds). Because +the room is bound, a reply in it ("draft an answer", "remind me Friday") is +scoped to that mailbox, reusing the topic-rooms reply-chain pattern. + +## Vault layout, threading, and processing + +### Paths and bucket + +`/emails/YYYY/MM/-.md` — the capture shape (`/s/…`, +kind `email`), already produced by `capture_email`. The **bucket comes from the +room binding, not hardcoded**: a shared family mailbox files to `family/emails/…` +(institutional, like documents); a person's account files to `/emails/…` +(personal, like their captures). Default = the bucket that owns the account. + +**Merge by date, do not subfolder per inbox.** Account + folder live in +frontmatter (and the room binding), not as a path level — consistent with the +rest of the vault, where identity is frontmatter + date path and the channel is +never a directory. Two inboxes to the same bucket merge on disk but stay distinct +rooms + distinct frontmatter; dedup by Message-ID keeps it safe. + +### Threading: one file per thread, folded (per ADR-010) + +An email thread *is* a reply chain, and [adr-010](../adr/adr-010-event-pipeline.md) +already says a filing's source is the whole thread and the vault entry is the +*fold* of it.

(Shipped.) +- **Each new message appends a dated section** — `publish_email_message` reads + the thread file, appends `## YYYY-MM-DD · sender` with the message's own + briefing (summary, facts, action items) and the verbatim body, and writes it + back. Persons and tags **union** into the thread's frontmatter so indexing + spans the whole conversation. (Shipped.) +- **Idempotent by construction** — each section carries an HTML-comment + `` marker; folding a message whose marker is already + present is a no-op. The file itself records which messages it contains, so a + re-run never double-files even before the fetcher's seen-set persists. The + vault is the source of truth (ADR-010), not a side cache. (Shipped.) +- **Reproducible**: re-fetch every message in the thread by Message-ID, re-fold. +- **Append vs. correct** — both are "reply chains" but mean different things: a + real inbound email *appends* (routes through `publish_email_message`, carrying + per-message `email_meta`); a Matrix reply from a family member *corrects* the + filing (a rewrite via `reprocess`). The presence of `email_meta` is what + distinguishes them, so a human correction is never folded as a new email. + +Staged status: thread-keying, per-message append, frontmatter union, and the +idempotency marker are **shipped**. Still to iterate: a *thread-level* rolled-up +summary (today each message keeps its own briefing), folding action items into a +single thread checklist, and wiring email `reprocess` to re-fold the whole +thread. + +### Summary gate for short mail + +Email runs the same classifier as everything else (title, summary, facts, +action_items, tags). But a two-line mail does not need an LLM summary — it would +be longer than the mail and waste a model call. So: + +- **Always keep the email body** (unlike a bookmark; the body *is* the content). +- **Gate the summary on length** — below ~a few hundred chars, skip the + `> [!summary]` briefing; the body stands alone. +- **Still extract action_items + tags when short** — cheap and the highest-value + bit ("send the form back Friday" is short but actionable).

A `mail` container owns the network-facing + himalaya (creds, scoped egress); the classify/file/route logic reuses the + docs pipeline via a mail bot in bot-runner (shared Maildir handoff).

Natural, but it couples Phase A's bot to Phase C's + drafting — keep read-only in Phase A, revisit once drafting exists. +7. **Binding UX.** Free-text question-and-answer on invite, a `bind + ` command, or a room-name convention like topic rooms' `Thema:` + prefix (e.g. `Post:`)?
