# AudioPen → PKB setup

Voice-note capture pipeline. AudioPen records on phone, polishes on their cloud, POSTs
the polished prose to your own infra. This vault's `inbox/raw/` receives the drop;
`scripts/audiopen-ingest.sh` normalises frontmatter and moves it to `inbox/`;
`/triage-inbox` routes it into `daily/`, `notes/`, `projects/`, or `reading/`.

Two ingest paths are supported. Pick one. Either works with the same
`/triage-inbox` downstream.

---

## Path A — Webhook via Tailscale Funnel (recommended)

**Requires.** Tailscale installed on the desktop with Funnel enabled on your tailnet.
Tailscale Funnel provides an outbound-initiated HTTPS endpoint (`*.ts.net`) with no
router configuration and no exposed ports. Nothing sits behind Authentik; AudioPen
hits the Funnel URL directly.

### 1. Generate a shared secret

```sh
head -c 24 /dev/urandom | base64 | tr -d '/+=' > /tmp/secret
cat /tmp/secret
```

Store it privately; it becomes part of the webhook URL.

### 2. Install the receiver systemd unit

```sh
mkdir -p ~/.config/audiopen-webhook ~/.config/systemd/user
printf 'AUDIOPEN_WEBHOOK_SECRET=%s\n' "$(cat /tmp/secret)" > ~/.config/audiopen-webhook/env
chmod 600 ~/.config/audiopen-webhook/env

cp /var/mnt/data/projects/council/scripts/audiopen-webhook/audiopen-webhook.service.example \
   ~/.config/systemd/user/audiopen-webhook.service

systemctl --user daemon-reload
systemctl --user enable --now audiopen-webhook.service
systemctl --user status audiopen-webhook.service  # should show active (running)
```

Tail logs:

```sh
journalctl --user -u audiopen-webhook.service -f
```

### 3. Install the ingest path + service units

```sh
# audiopen-ingest.service — normalises raw drops
cat > ~/.config/systemd/user/audiopen-ingest.service <<'EOF'
[Unit]
Description=Normalise AudioPen drops into council/inbox/

[Service]
Type=oneshot
ExecStart=/var/mnt/data/projects/council/scripts/audiopen-ingest.sh
Environment=COUNCIL_REPO=/var/mnt/data/projects/council
EOF

# audiopen-ingest.path — fires the service whenever inbox/raw/ gains a file
cat > ~/.config/systemd/user/audiopen-ingest.path <<'EOF'
[Unit]
Description=Watch council/inbox/raw for new AudioPen drops

[Path]
PathChanged=/var/mnt/data/projects/council/inbox/raw
Unit=audiopen-ingest.service

[Install]
WantedBy=default.target
EOF

systemctl --user daemon-reload
systemctl --user enable --now audiopen-ingest.path
```

### 4. Expose the receiver via Tailscale Funnel

```sh
tailscale funnel --bg 8765
tailscale funnel status   # show the public URL
```

Your endpoint is now `https://<your-host>.<tailnet>.ts.net:443/`. AudioPen will
POST to `https://<your-host>.<tailnet>.ts.net/audiopen/<secret>`.

### 5. Configure AudioPen

In AudioPen (web or mobile app): settings → integrations → add a generic webhook.

- **URL:** `https://<your-host>.<tailnet>.ts.net/audiopen/<secret>`
- **Method:** POST
- **Content-Type:** application/json
- **Trigger:** after each recording is polished

AudioPen typically sends JSON with keys like `title`, `body`, `orig_transcript`.
The receiver accepts any of these; if AudioPen changes shape, check
`journalctl --user -u audiopen-webhook.service` for the logged payload and
update `scripts/audiopen-webhook/main.py::extract_content()` if needed.

### 6. Test end-to-end

```sh
SECRET=$(awk -F= '/AUDIOPEN_WEBHOOK_SECRET/ {print $2}' ~/.config/audiopen-webhook/env)
FUNNEL=$(tailscale funnel status | awk '/https:/ {print $1; exit}')

curl -X POST -H 'Content-Type: application/json' \
  -d '{"title":"Test","body":"Hello from curl. This is a test drop."}' \
  "${FUNNEL%/}/audiopen/${SECRET}"
# → ok

ls /var/mnt/data/projects/council/inbox/raw   # should contain the test file briefly
sleep 2
ls /var/mnt/data/projects/council/inbox       # should now contain the normalised file
```

Then record an actual voice note in AudioPen, wait for polishing, confirm the same
flow. Run `/triage-inbox` in Claude Code when you're ready to route the contents.

## Path B — Email → IMAP fetch (no-open-ports fallback)

Use this if you don't run Tailscale / Cloudflare Tunnel and don't want to stand one
up. Fully outbound: AudioPen emails each note; a cron on the desktop pulls via IMAP
and drops files in `inbox/raw/`.

### 1. Dedicated email address

Create or repurpose a mailbox for AudioPen's output. Options:

- Fastmail alias → Fastmail IMAP on desktop (works).
- Self-hosted mail server → pull via IMAP from localhost (works).
- Gmail "+audiopen" alias → fine but adds Google to the dependency chain.

### 2. IMAP fetch script (stub — you'll customise for your mail server)

```python
#!/usr/bin/env python3
"""Minimal IMAP fetcher: pulls unread messages from a mailbox, writes them as
bare markdown to inbox/raw/. Uses stdlib imaplib. Keep credentials in
~/.config/audiopen-mail/env or similar."""
import imaplib, email, os, re, pathlib, datetime

HOST   = os.environ["IMAP_HOST"]
USER   = os.environ["IMAP_USER"]
PASS   = os.environ["IMAP_PASS"]
MBOX   = os.environ.get("IMAP_MAILBOX", "INBOX")
INBOX  = pathlib.Path(os.environ.get("COUNCIL_INBOX_RAW",
                                     "/var/mnt/data/projects/council/inbox/raw"))
INBOX.mkdir(parents=True, exist_ok=True)

m = imaplib.IMAP4_SSL(HOST)
m.login(USER, PASS)
m.select(MBOX)
typ, data = m.search(None, 'UNSEEN')
for num in data[0].split():
    typ, msg_data = m.fetch(num, '(RFC822)')
    msg = email.message_from_bytes(msg_data[0][1])
    title = (msg.get("Subject") or "Untitled").strip()
    body = ""
    if msg.is_multipart():
        for p in msg.walk():
            if p.get_content_type() == "text/plain":
                body = p.get_payload(decode=True).decode('utf-8', errors='replace')
                break
    else:
        body = msg.get_payload(decode=True).decode('utf-8', errors='replace')
    slug = re.sub(r"[^a-z0-9]+", "-", title.lower()).strip("-")[:60] or "untitled"
    ts = datetime.datetime.now().strftime("%Y-%m-%d-%H%M")
    (INBOX / f"{ts}_{slug}.md").write_text(f"# {title}\n\n{body}\n")
    m.store(num, '+FLAGS', '\\Seen')
m.logout()
```

Save as `scripts/audiopen-imap-fetch.py`. Run it every N minutes via a systemd
user-timer or cron. The same `audiopen-ingest.path` unit (from Path A, step 3)
picks up the drops from there.

### 3. Configure AudioPen

Settings → integrations → email output → recipient = your dedicated address.
Each recording → one email. Done.

## Routine

Once everything is wired:

1. **Capture**: voice note → AudioPen → (webhook or email) → desktop.
2. **Ingest**: automatic — you don't run anything; systemd fires on file change.
3. **Route**: when you want, open a Claude Code session in the vault and run
   `/triage-inbox`. Koskela proposes destinations; you approve in batch.
4. **Weekly/monthly**: the promoted notes are already in their homes; `/reflect`,
   `/review-week`, and `/review-month` will see them naturally.

## Troubleshooting

| Symptom | Check |
|---|---|
| Files pile up in `inbox/raw/` but never normalise | `systemctl --user status audiopen-ingest.path audiopen-ingest.service` — path unit enabled? service errored? Run the script manually once: `bash scripts/audiopen-ingest.sh`. |
| Webhook POSTs 200 but no file lands | Check the systemd logs for the receiver: `journalctl --user -u audiopen-webhook.service -n 50`. The logged path should be writable and under `inbox/raw/`. |
| Webhook POSTs 404 | Secret mismatch between AudioPen URL and `~/.config/audiopen-webhook/env`. Regenerate and re-set both sides. |
| Funnel URL unreachable | `tailscale status`; `tailscale funnel status`. Re-run `tailscale funnel --bg 8765`. Confirm Funnel is enabled on your tailnet (admin → DNS → HTTPS Certificates; admin → Access controls → Funnel). |
| Normalised file missing frontmatter | Bug in the ingest wrapper; open the raw file, run the script with `bash -x scripts/audiopen-ingest.sh` to trace. |
