The three surfaces did not agree on what renaming a tag onto a name another
one already holds should do, and none of the three answers was good.
I described this wrongly first time and the correction matters. The local
store does NOT silently create a duplicate: `idx_labels_name` is unique on
`lower(name)`, so the bare UPDATE in `rename_label` failed, and the user got
a raw SQLite "UNIQUE constraint failed" as their error message. The server
meanwhile answered 409 "a tag with that name already exists" — and only on
an EXACT match, because its constraint is on the raw name while every
client's index is on `lower(name)`.
That last part is the sharper bug. The server would happily hold "Groceries"
beside "groceries"; no synced client can store both. Creating that pair on
the web armed a pull that fails later, on a phone, in a path with no UI.
Operator's call: a rename onto an existing name means merge — typing an
existing tag's name onto this one says they are the same thing.
* `store::rename_label` and the server's PATCH now implement one rule.
THE OLDER ROW SURVIVES and takes the new spelling. Age rather than "the
one that already held the name", so that renaming A→B and B→A land on
the same survivor; otherwise the outcome depends on which way round
someone typed it, and two devices tidying the same pair disagree about
which id still exists. Ties go to the incumbent, so it stays
deterministic.
* The core reuses `merge_labels` rather than reimplementing the move. That
is the only place that knows to mark every affected NOTE dirty before
the delete cascades the membership rows away, which is what makes a
merge reach the server at all.
* The server's rename and its `/merge` route now share one `_merge_into`
helper, for the same reason.
* Both server lookups became case-INSENSITIVE, matching every client. The
create path is included: it was the one actually minting the unstorable
pair, so fixing only the rename would have left the door open.
* The web asks before merging, naming both note counts. A merge cannot be
undone by repeating it and is now reachable by a typo in a text field —
the same reasoning as the delete confirmation in #2116. The confirmation
lives in the shared store, so the desktop gets it too; the FFI does not
ask, because that belongs to the surface with a person in front of it.
* The web store detects the merge from the LIST, not the response: the
survivor may be the row we asked to rename, so an unchanged id proves
nothing.
Tests: three integration tests over a real database (both rename directions
land on the older row; a case-varied create returns the existing tag) and
two through the Android FFI, which is the binding the phone will use.
Also fixes a straggler from 8c7553d — the delete confirmation still said
"the label".

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

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>onmainonly (immutable, the rollback unit). There are no version-shaped tags: nothing pins one, and the build reports its own version at/api/configand/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): 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).
