The skeleton, and the lane that builds it. Gradle invokes cargo-ndk to
cross-compile thoughtsync-ffi for four ABIs, generates the Kotlin bindings from
the resulting .so, and packages both.
BUILT ON MINSTREL'S TOOLCHAIN, not a fresh guess. Gradle 9.1.0 / AGP 9.0.1 /
Kotlin 2.3.21 on JDK 25 is the combination already proven in this family on
ci-android, including the JDK 22+ native-access opt-in the launcher JVM needs
and the artifact-upload action pinned by SHA (issues 2255 / 2270). It also
independently confirms the JDK 25 call made on ci-rust-android in step 3.
Gradle wiring worth noting:
* ExecOperations, not project.exec — the latter was REMOVED in Gradle 9, and
touching `project` at execution time is also what breaks the configuration
cache this build enables.
* The cargo task's inputs are the Rust SOURCES, not the workspace directory.
Declaring the directory would make Gradle hash target/, which is gigabytes.
* Bindings are generated with `--library` against the built .so, so they can
never describe a different version of the Rust than the one being packaged.
* cargo runs --locked, so an Android build cannot silently re-resolve the
lockfile the desktop lanes are gated on.
JNA is a real dependency, with the @aar classifier. The plain jar builds fine
and fails at runtime with UnsatisfiedLinkError, which is the worst way to learn
it. R8 keep rules for JNA and the bindings are in for the same reason — that
failure would otherwise appear only in a minified release.
The UI is a working board, not a debug screen: capture field, note list, empty
state, error banner, and an honest failure screen for a store that won't open.
Rules 23/24 — a surface ships at quality from the first commit. Capture uses the
IME action key because the north star is a thought captured in under a second,
and leaves the title empty so the core derives it from the first body line.
Every core call runs on Dispatchers.IO: they are blocking FFI into synchronous
SQLite, and running them on the main thread is exactly the jank going native was
meant to avoid.
The launcher icon reuses frontend/public/icon-maskable-512.png as an adaptive
foreground on the brand #F5C518 — the same asset and colour the web app already
ships, so the three surfaces wear one face.
No signing config. A release keystore that has passed through an agent session
or shell history is compromised by construction (task 2136); it has to be
generated by the operator and reach CI only as a secret. CI builds debug.
CI can only prove this BUILDS — a Linux runner cannot execute an APK, so feel
and on-device correctness remain an operator pass on an emulator.
Scribe #2739.

ThoughtSync
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/thoughtsync/ 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 THOUGHTSYNC_DATABASE_URL):
pip install -e ".[dev]"
alembic upgrade head
hypercorn 'thoughtsync.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: thoughtsync
POSTGRES_PASSWORD: CHANGE_ME # change this
POSTGRES_DB: thoughtsync
volumes:
- thoughtsync-db:/var/lib/postgresql/data
healthcheck:
test: ["CMD-SHELL", "pg_isready -U thoughtsync"]
interval: 5s
timeout: 5s
retries: 10
app:

restart: unless-stopped

Then open http://<host>:5000 and register — the first account becomes the admin.
- Only
THOUGHTSYNC_DATABASE_URLis required.THOUGHTSYNC_SECRET_KEYis optional; if unset, a signing key is generated and persisted in the database (sessions survive restarts). - Uploaded images live under the
thoughtsync-datavolume at/var/thoughtsync. - The app waits for the database and runs migrations (
alembic upgrade head) automatically on start. - Image tags:
:latest(stable, built frommain) ·:dev(latestdevbuild) ·:<git-sha>(immutable, for pinning / rollback). - Install as an app (PWA): ThoughtSync 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) — plainhttp://<host>:5000won'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_URLis 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).
