Three threads from the recent UX iteration:
1. Reminder list / detail no longer shows raw "Cron: 32 11 * * *"
----------------------------------------------------------------
`describeRecurrence` for a kind=cron spec used to emit
"Cron: <expr>" verbatim, which is unreadable on the list row's
recurrence line.
New pure helper `describeCronRule(rule)` parses the cron shapes
the recurrence picker produces and renders them as natural
sentences:
"0 9 * * *" → "Every day at 09:00"
"0 9 * * 1-5" → "Every week on Mon, Tue, Wed, Thu, Fri at 09:00"
"0 9 * * 1,3,5" → "Every week on Mon, Wed, Fri at 09:00"
"0 9 1,15 * *" → "Every month on days 1, 15 at 09:00"
"0 9 13 5 *" → "Every year in May on day 13 at 09:00"
"30 17 1,15 1,4,7,10 *" → "Every year in Jan, Apr, Jul, Oct on days 1, 15 at 17:30"
Multi-line rules ("0 9 * * 1\n0 17 * * 5") join the per-line
descriptions with " · " for compactness in the list density.
Long DOM lists (>6 days) collapse with a "+N more" tail to keep
the line short; same convention the picker's per-row preview uses.
Unrecognised shapes (e.g. "*/5 * * * *") fall back to the raw
expression — better than swallowing entirely.
2. HEIC/AVIF magic-byte sniffing at upload
----------------------------------------------------------------
The mime-only check we shipped earlier missed iOS Safari's
habit of uploading HEIC photos with Content-Type: image/jpeg.
The file then made it to the bot, where Sharp's HEIF decoder
plugin is missing, the thumbnail extraction failed, and the
message went out without a working preview — read by the user
as "image still not send".
New helper `sniffUnsupportedImage(bytes)` reads bytes 4..11 of
the upload and looks for the ISOBMFF "ftyp" marker followed by
one of the brands Sharp can't decode (HEIF: heic / heix / hevc
/ heim / heis / mif1 / msf1; AVIF: avif / avis). Brand match is
case-insensitive. Plain JPEG / PNG / unrelated ftyp brands like
mp4 are not flagged.
`uploadMediaAction` now runs the sniff against the buffered
bytes before persisting, returning the same "Images are not
supported, please re-upload images" error as the mime path.
3. Sidebar brand link → dashboard tests
----------------------------------------------------------------
Asserts the desktop <aside> contains an <a href="/" aria-label=
"Go to dashboard"> at the top, scoped via a new extractSidebar
helper so it can't accidentally match the mobile-header brand
link (which uses aria-label="Go home"). A second test confirms
the two aria-labels stay distinct.
22 web test files / 232 passing (was 212):
- +12 cron-description cases in lib/recurrence.test.ts
- +6 magic-byte sniff cases in lib/whatsapp-media.test.ts
- +2 sidebar-brand-link cases in app-shell.test.tsx

cm WhatsApp Reminder Bot
Self-hosted WhatsApp reminder bot. Pairs multiple WhatsApp accounts via Telegram-delivered QR codes and sends scheduled reminders to groups.
Status
Plan 1 complete. Foundation, DB schema, and Telegram-driven WhatsApp pairing are working end-to-end. Reminder scheduling, the web dashboard, and production deploy are upcoming plans (docs/superpowers/plans/).
What's working today:
- Single-operator Telegram bot with a whitelist + audit log of every command.
- BotFather-style menu navigation:
/menuopens a single message that edits in place as you navigate. - Pair a new WhatsApp account with
/menu→ 📡 Pair New → reply with a label. QR is delivered to Telegram and refreshed in place as it expires. - Browse paired accounts with 📒 Accounts. Tap an account → see groups, send a test text message, or unpair.
- Group sync runs at pairing and on every Baileys
groups.upsert/groups.updateevent, plus a manual 🔄 Refresh button. Removed groups are pruned automatically. - Auto-reconnect on transient drops; restart-survival via Baileys
useMultiFileAuthState(no QR rescan needed across container restarts as long as WhatsApp hasn't logged the device out).
Host requirements
Only Docker. No host Node, pnpm, or any other language toolchain — everything runs in containers via the long-lived tools service.
Architecture in one paragraph
Two app containers and one external dependency. bot (Node.js) holds the live Baileys WhatsApp sessions, the grammy Telegram bot, and (in plan 2) a pg-boss scheduler. web (Next.js, plan 3) is stateless UI + API. tools is a long-running Node 22 + pnpm sidecar used for installs/tests/typechecks/migrations so the host doesn't need a Node toolchain. Postgres lives external at 192.168.0.210 in a wabot database. All cross-service communication goes through Postgres (LISTEN/NOTIFY for events, table writes for state).
Full design spec: docs/superpowers/specs/2026-05-03-whatsapp-bot-design.md
Quick start (dev)
Prerequisites: Docker, the wabot database + waBot role on 192.168.0.210 (with a pg_hba.conf line permitting 192.168.0.0/24), and a Telegram bot token from @BotFather.
# 1. Configure env
cp envs/.env.example .env.development
# edit .env.development: real DATABASE_URL, TELEGRAM_BOT_TOKEN, your TG user ID
scripts/gen_auth_secret.sh --write
# 2. Bring up the tools container, install deps
NO_SUDO=1 scripts/dev.sh up
NO_SUDO=1 scripts/dev.sh pnpm install
# 3. Apply migrations and seed your operator row
NO_SUDO=1 scripts/db.sh migrate
NO_SUDO=1 scripts/db.sh seed
# 4. Watch the bot service
NO_SUDO=1 scripts/dev.sh logs bot
In Telegram, message your dev bot /menu, tap 📡 Pair New, reply with a label, scan the QR.
NO_SUDO=1 is the right setting if your user is in the docker group (the default for this repo). Drop it if you need sudo docker.

Scripts
All pnpm/tsx/drizzle-kit invocations run inside the tools container, so no host Node is needed.
