android: the device token is stored sealed under a Keystore key
Family idea #5105, practice 12, as the operator chose on 2026-10-08: the token
is encrypted, and Android backup stays on.

The core:
- Adds a TokenSeal trait in sync/state.rs, with set_sealed_link and
  open_token.
- A sealed token is stored as "sealed:<value>".
- A plain token, stored before this change or while sealing failed, is sealed
  in place on its next read.
- A sealed token that won't open is dropped, and the server address and cursor
  are kept, so the app reads as unlinked and asks to sign in again. That is
  what happens after Android restores the app onto another phone.
- The desktop passes no seal and keeps storing the token as before.

The FFI:
- Exports TokenSeal as a uniffi foreign trait (seal_token / open_token, null
  rather than an exception).
- Requires it in Inkwell's constructor, so there is no moment a token could be
  stored unsealed.
- Routes credentials(), unlink() and store_link() through it.

Kotlin:
- KeystoreTokenSeal is AES-GCM under an Android Keystore key, using the
  SealedBox framing from Minstrel's KeystoreSessionVault (Scribe snippet #5025),
  with no new dependency.
- SealedBoxTest checks the framing on the JVM.

allowBackup stays true, and the manifest says why. An unlinked phone's notes
exist only on the phone, and the backup is their one other copy. The backup
carries a token nothing can open.

Inkwell

Self-hosted personal thought-capture web app in the FabledSword family — a Google-Keep-style masonry post-it board for capturing disparate thoughts in under a second, designed to grow into a lightweight second brain (labels, search, [[wiki-links]], graph).

  • Stack: Quart (async Python) + Vue 3 + PostgreSQL, Docker, Fabled-Git CI.
  • Auth: native email + password (signed-cookie sessions). Multi-user with the family owner + direct-share + group-share ACL.
  • Web-first. An Android companion is a later, conditional milestone.

Layout

src/inkwell/         Quart app (app factory, auth, models, ACL, config, db)
alembic/             async migrations (schema built via `alembic upgrade head`)
tests/               DB-free unit tests (pytest)
frontend/            Vue 3 + Vite + TypeScript + Tailwind SPA
Dockerfile           2-stage build (Vue -> python:3.12-slim runtime)
docker-compose.yml   local app + Postgres stack

Development

Backend (needs a Postgres reachable at INKWELL_DATABASE_URL):

pip install -e ".[dev]"
alembic upgrade head
hypercorn 'inkwell.app:create_app()' --bind 0.0.0.0:5000

Frontend (proxies /api to :5000):

cd frontend
npm install
npm run dev        # http://localhost:5173

Or run it in Docker. Hot-reload dev stack (edit code, changes reload live) — Postgres + backend + Vite dev server, app at http://localhost:5173:

docker compose -f docker-compose.dev.yml up

Or the full production image (SPA baked in) at http://localhost:5000:

docker compose up --build

Deploy (self-host)

A complete two-container stack (app + Postgres) you can copy and run. Save it as docker-compose.yml, change the two CHANGE_ME passwords (they must match), then docker compose up -d:

services:
  db:
    image: postgres:16-alpine
    restart: unless-stopped
    environment:
      POSTGRES_USER: inkwell
      POSTGRES_PASSWORD: CHANGE_ME          # change this
      POSTGRES_DB: inkwell
    volumes:
      - inkwell-db:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U inkwell"]
      interval: 5s
      timeout: 5s
      retries: 10

  app:
    image: git.fabledsword.com/bvandeusen/inkwell:latest   # :dev for the current dev build
    restart: unless-stopped
    depends_on:
      db:
        condition: service_healthy
    environment:
      INKWELL_DATABASE_URL: postgresql+asyncpg://inkwell:CHANGE_ME@db:5432/inkwell
    volumes:
      - inkwell-data:/var/inkwell   # uploaded images; omit if you don't use attachments
    ports:
      - "5000:5000"

volumes:
  inkwell-db:
  inkwell-data:

Then open http://<host>:5000 and register — the first account becomes the admin.

  • Only INKWELL_DATABASE_URL is required. INKWELL_SECRET_KEY is optional; if unset, a signing key is generated and persisted in the database (sessions survive restarts).
  • Uploaded images live under the inkwell-data volume at /var/inkwell.
  • The app waits for the database and runs migrations (alembic upgrade head) automatically on start.
  • Image tags: :latest (stable, built from main) · :dev (latest dev build) · :<git-sha> on main only (immutable, the rollback unit). There are no version-shaped tags: nothing pins one, and the build reports its own version at /api/config and /health.
  • Putting it on the public internet: there are four things to do first — close registration, terminate TLS and forward X-Forwarded-Proto, stop publishing the app port, and back up the attachment volume as well as the database. See docs/public-hosting.md, which also lists what the app hardens on its own and what it deliberately doesn't.
  • Install as an app (PWA): Inkwell is installable ("Add to Home Screen" / the browser's install button) for an app-like window. Browsers only offer install over a secure context, so put the app behind a reverse proxy terminating HTTPS (or reach it via localhost) — plain http://<host>:5000 won't show the install prompt.

Milestones

  • M0 — Foundation & Identity ✅: Quart+Vue+Postgres skeleton, native auth, sharing-ACL spine, Fabled-Git CI.
  • M1 — Capture Core ✅: note model + masonry board (quick-add, colors, pin, edit-in-place, archive, trash+restore).
  • M1.5 — Roles & DB-backed Settings ✅: first user is admin, admin Settings UI, DATABASE_URL is the only required env.
  • M2 — Organize: labels/tags, search, checklists, attachments.
  • M3 — Second-brain seeds: [[wiki-links]], backlinks, graph view, reminders.
  • M4 — Launch hardening: responsive/PWA, settings UI, polish.

Work happens on dev; main is protected (PR-only).
