Local -> server, then push-then-pull as the only ordering the UI can invoke.
LOCAL TOMBSTONES (schema v2). Found while writing push: delete_forever and
remove_label just DROPPED the row, leaving no record it existed. Offline that
means the delete can never be pushed — and the next pull faithfully
resurrects the note from the server. A deletion that undoes itself is about
the worst thing sync can do, so deletes now record into pending_deletes until
the server acknowledges them. merge_labels had the same hole.
merge_labels also moved memberships without marking the affected notes dirty.
A note's label set only reaches the server via the note itself, so a merge
looked done locally and never synced. Now marked before the delete cascades
the rows away.
Result handling, per status:
created/applied -> clear dirty, store the returned sync_revision
noop -> clear dirty, drop the tombstone (a row the server never
saw, created and deleted entirely offline)
kept -> clear dirty WITHOUT touching content. Re-pushing would
lose the same last-write-wins comparison forever; the
following pull adopts the server's version.
rejected -> stay dirty and surface the reason. A duplicate label name
is the realistic case and only a human can resolve it.
The subtle one is `kept` plus a skewed clock. Normally the server's kept
revision sits above our cursor, so the next pull fetches it anyway. If the
clock makes a genuinely later local edit look older, that revision can be
BELOW the cursor — the pull skips it and the stale local copy stays on screen
with nothing marking it wrong. So a kept result at or below the cursor
rewinds the cursor to re-fetch that note. Both directions tested.
label_ids carries MANUAL memberships only. Tag-sourced ones are re-derived
server-side from the body; sending them would convert them into manual
assignments that no longer disappear when the #tag is deleted from the text.
engine::run_cycle is push-then-pull, and a failed push ABORTS before the
pull — pulling anyway would overwrite the exact rows we just failed to save,
turning a recoverable network error into lost work. sync_pull is removed from
the command surface accordingly: offering a bare pull would hand the UI a way
to discard unsent edits. sync_now and sync_has_pending replace it.
Both loops have anti-spin guards: push stops when a batch clears nothing,
pull stops when the cursor doesn't advance.
15 push tests against an in-memory database.

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

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).
