Esa Kataja 0f15ae0bfc Release 2026.08.02-1
SQLite replaces Postgres, and two fixes from using the thing.

- The database is a file under ./storage instead of a second container. Ten
  members never needed a database server, and the driver is pure Go, so the
  build stays CGO_ENABLED=0 and the dependency count is unchanged. One bind
  mount is now the whole backup: no pgdata, no healthcheck-gated depends_on,
  no startup retry loop. Timestamps are UTC text, idle_ttl is seconds, the
  divisive/unified boards carry their own stddev, and foreign keys are on by
  pragma. Tests get a database file each and run without any setup
- Invites are copied, not clicked. An invite is something to send, and the
  anchor opened the join form in the admin's own browser
- Feedback asks for more than faults: the footer reads "Ongelmia? Ideoita?
  Palautetta?" and the page behind it invites ideas rather than only bugs
- Kuuntele YouTubessa opens in a new tab, so a half-typed review survives it

Esa Kataja 400b5d3833 Release 2026.08.01-1
Lyrics, versioning, and the song page's fact line.

- Lyrics are suggested at submission and never imposed: the worker makes one
  LRCLIB lookup, and Hae sanoitukset re-queries with whatever title and artist
  are typed. Neither overwrites what the submitter wrote. They live on the
  submission, travel to the song at publish, and stay editable after the song
  locks — the lock freezes what a song claims to be, and nobody reviewed the
  lyrics
- The review strip reads and writes side by side: lyrics left, review right.
  Synced LRC highlights the playing line and seeks on click; plain text scrolls
  continuously with a nudge knob. Following can be turned off
- CalVer YYYY.MM.DD-N, injected from the git tag with -ldflags, shown in the
  footer, the startup log and /healthz
- The song page's metadata became four labelled cells instead of one flat run
  of five different kinds of fact

Fixes: publishing wiped lyrics the worker had just fetched (a request that
omitted a field cleared it), lyric auto-scroll landed in the wrong place, and
the fader shifted the deck sideways at score 100.

Esa Kataja 1b3bbbbd7b Release 2026.07.31-1
First release of the Go rewrite: invite-only membership, the submission
pipeline for uploads and YouTube, the queue and review loop with the reveal
rule, stats, profiles, avatars and palaute.

## Admin page
## Admin panel
An admin is **an ordinary member with `is_admin` set** — the same account, the same login, the same
session cookie. Admins submit and review like anyone else; the flag adds a Ylläpito link to the nav
and unlocks `/admin` on the normal listener. A signed-in member without the flag gets a 404 there.
The admin is **not a user account**. It exists only as `ADMIN_USER` / `ADMIN_PASSWORD`, authenticates
with HTTP Basic Auth, and is bound to loopback so it is not reachable from the internet. Reach it
through an SSH tunnel:
From `/admin`: mint invites, reset member passwords, ban members, delete songs, read issue reports.
```sh
ssh -L 8081:127.0.0.1:8081 you@server
# then open http://localhost:8081
```
An admin cannot ban themselves, since banning drops every session for the target and nothing would
be left to undo it.
From there: mint invites, reset member passwords, ban members, delete songs, read issue reports.
**Lost the admin password?** There is no recovery endpoint and no recovery key. Reset the hash
directly in the SQLite file, the same as for any locked-out member.
**Lost the admin password?** Edit `.env` and `docker compose restart app`. There is no recovery
endpoint and no recovery key — the credentials are the environment.

## Layout
`src/` is the whole program: one flat `package main`, with the assets it embeds beside it, because
`//go:embed` cannot reach outside its own directory. `templates/` and `static/` are those assets,
`migrations/` holds numbered `.sql` files applied in order at startup, and `testdata/` holds the
golden JSON files that guard the API contract, plus `ytdlp-noose.json`a real `yt-dlp -J` dump of
an ordinary upload, used to test metadata prefill against a video that has no `track`, `artist` or
`album` at all.
The root keeps what is not source: `docs/`, the container and compose files, the `Makefile`, and
`storage/` once the app has run.
| Command | Does |
|---|---|
| `make` | gofmt, `go vet`, `go test` — everything that must pass before a commit |
| `make run` | Build and start on `127.0.0.1:8080` with development defaults |
| `make fix` | Show `go fix` modernizer suggestions as a diff, without applying them |
| `make image IMAGE=…` | Build a release image tagged from `git describe`; refuses an untagged HEAD |
| `make db` / `make backup` | SQLite shell, and a WAL-safe snapshot, against the running container |
Go source is flat at the repository root, one package. Beyond that: `templates/` and `static/` are
embedded assets, `migrations/` holds numbered `.sql` files applied in order at startup, and
`testdata/` holds the golden JSON files that guard the API contract, plus `ytdlp-noose.json` — a real
`yt-dlp -J` dump of an ordinary upload, used to test metadata prefill against a video that has no
`track`, `artist` or `album` at all.

retention `DELETE`, a table and a filtered page — ~150 lines to avoid `docker compose logs`. If
in-app visibility is ever wanted, build an *audit* view of domain events instead; those are
queries over tables that already exist.
8. **The admin is a member with `is_admin` set.** ~~The admin is not a user.~~ *Reversed.* The
original call — env credentials, Basic Auth, its own loopback listener — bought network isolation
at the price of a second port to tunnel and proxy, and a second credential in the password
manager. Basic Auth also sat outside the `SameSite` protection the member cookie already had, and
left admin actions with no actor to log. One boolean column reuses the session, the login rate
limiter, the ban-drops-sessions path and CSRF protection that all existed anyway. The costs the
original entry named are real but small here: seeding is `seedAdmin` on an empty database, and
the only lockout rule is that an admin cannot ban themselves. Banning a *second* admin is allowed
— with one admin per installation there is no last-admin case to protect.
9. **No moderator tier.** A four-level role enum was considered and dropped: nothing in the admin
surface distinguishes a superadmin from an admin, and moderator is a second column on the day
somebody needs to resolve reports without also being able to reset passwords.
8. **The admin is not a user.** Env credentials, Basic Auth, its own loopback listener. This deletes
the `role` column, first-launch seeding, admin sessions, the "cannot ban the last admin" rules,
and every "exclude the admin" clause that would otherwise appear in user and stats queries.
9. **Same process, two listeners** — not a second binary. A management binary would need its own
deploy and would race the startup migrations. Two listeners give the network isolation, which was
the only real benefit.
10. **The admin recovery endpoint is dropped.** The old app had a key-gated credential reset with a
`qwerty123` default in `docker-compose.yml`. There is no route, no key and no default: an admin
who loses their password is reset from the database, the same as any locked-out member.
`qwerty123` default in `docker-compose.yml`. The password is an env var now, so recovery is
editing it and restarting. No route, no key, no default.
11. **Conversion runs in the background; nothing enters `songs` until it succeeds and the submitter
confirms.** Costs a `submissions` table, buys a `songs` table where every row is a real song and

tabulated in the [README](../README.md#configuration); this file is the procedures.
The whole deployment is **one container and one directory**. There is no database server, no
migration step to run by hand, and no build on the target machine.

## The server's compose file
The `docker-compose.yml` in the repository root **builds from source** — that is the development
one, and it is what you want on a machine that has the code checked out. A server has no source, so
it runs a published image instead. Keep this second file on the server; it is not in the repository
because it describes one particular deployment rather than the app.

- ./storage:/storage
ports:
- "8080:8080"

```
Two differences from the development file, and the reason for each:
| | Development | Server |
|---|---|---|
| Source of the binary | `build:` from the checkout | `image:` pulled from the registry |
| Version | `VERSION` build arg, `dev` by default | baked into the tagged image |
There is one port. `/admin` rides the member listener behind the same session cookie as everything
else, so there is nothing extra to publish, tunnel or firewall.
Alongside it, a `.env` — same variables as [.env.example](../.env.example), plus the image:
```sh
IMAGE=registry.example.com/owner/levyraati26-go:2026.08.02-1
ADMIN_EMAIL=# first start only
ADMIN_PASSWORD=# first start only
SECURE_COOKIES=true
PUBLIC_URL=https://levyraati.example.com
```
---
## What the server needs
- Docker with the Compose plugin, or Podman with `podman-compose`.
- Credentials for the registry holding the image (`docker login <registry>`), unless it is public.
- A reverse proxy terminating TLS in front of port 8080. Cookies are `Secure`, so the members' site
over plain HTTP will not keep anyone logged in.
- Outbound network access: yt-dlp reaches YouTube, and the lyrics lookup reaches LRCLIB. Neither is
fatal to lose — submissions fail with a visible message and lyrics stay empty.
Nothing else. No Go toolchain, no ffmpeg on the host — those live in the image.
---
## Building and publishing a release
Done from a checkout, not on the server. The version reaches the binary only through the build arg,
so it must match the tag or `/healthz` will lie about what is deployed:
```sh
git switch main && git merge dev
git tag 2026.08.02-1
podman build --build-arg VERSION=2026.08.02-1 \
-t registry.example.com/owner/levyraati26-go:2026.08.02-1 \
-t registry.example.com/owner/levyraati26-go:latest .
podman push registry.example.com/owner/levyraati26-go:2026.08.02-1
podman push registry.example.com/owner/levyraati26-go:latest
```
Check before pushing that the tag took: `podman run --rm -p 8099:8080 -e ADMIN_PASSWORD=x IMAGE`
then `curl localhost:8099/healthz` should answer `ok 2026.08.02-1`, not `ok dev`.
---
## First deployment
Two files go on the server — the compose file above and `.env`. **Not** a git clone; the source is
not needed to run this.
```sh
mkdir -p /srv/levyraati && cd /srv/levyraati
# put docker-compose.yml and .env here
chmod 600 .env # it holds the only admin credential there is
docker compose pull
docker compose up -d
docker compose logs -f app # watch the migrations apply
```
The first start creates `./storage` with `audio/`, `avatars/`, `tmp/` and `levyraati.db`, applies
every migration, and only then accepts connections. It creates **no users** — nobody can register
until you mint an invite.
Confirm it is alive, and that the version is the one you meant to deploy:
```sh
curl -s localhost:8080/healthz # -> ok 2026.08.02-1
```
### Reverse proxy
Proxy your public hostname to `127.0.0.1:8080`. Two things matter beyond the defaults:
- **Upload size.** Submissions are capped at 50 MB by the app; a proxy with a 1 MB default body
limit rejects them first, and the error is not the app's clear one. Raise it past 50 MB
(`client_max_body_size 64m` in nginx, `MaxRequestBodySize` in Caddy).
- **Response buffering off**, or at least generous timeouts, for `/audio/{id}` — it serves Range
requests so the player can seek.
### Admin access
Log in as your own account and open `/admin`. Nothing to tunnel, nothing extra to proxy: the page is
part of the site and is gated on the `is_admin` flag on your user row. A signed-in member without the
flag gets a 404 there, so the page does not advertise itself.
TLS at the proxy is what makes the invite *Kopioi* button work — the clipboard API needs a secure
context, and `https://` is one. Over plain HTTP on a real hostname the button will not fire.
From the page: mint invites, reset passwords, ban members, delete songs, read feedback.
**First start.** On an empty database the app creates one account from `ADMIN_EMAIL` /
`ADMIN_PASSWORD` and marks it admin. Once it exists those variables do nothing; drop them from
`.env` if you would rather not keep a password there.
**Lost the admin password?** There is no recovery endpoint and no recovery key. Set a new bcrypt
hash directly in the SQLite file — re-running the app with `ADMIN_PASSWORD` will not help, because
seeding only fires on an empty `users` table.
---
## Upgrading
```sh
cd /srv/levyraati
# back up first — see below; it takes a second and this is exactly when you want it
$EDITOR .env # point IMAGE at the new tag
docker compose pull
docker compose up -d
curl -s localhost:8080/healthz # confirm the new version is answering
```
Migrations run at startup, inside the new container, before it serves. There is no separate step.
**Expect a few seconds of downtime.** One container, one SQLite file, no rolling deploy — and a
restart deliberately fails every in-flight submission. Deploy when nobody is mid-review.
### Rolling back
Point `IMAGE` at the previous tag and `docker compose up -d`. **Only safe if the release you are
leaving added no migration** — migrations are forward-only and the old binary will not understand a
schema it has never seen. Check `migrations/` between the two tags first; if one landed, restore the
backup taken before the upgrade instead.
### What a restart does to work in progress
Conversions run as goroutines inside the process, so a restart kills them. This is handled, not
ignored: the startup sweep marks every submission still `queued`, `downloading` or `converting` as
`failed` with "interrupted by restart", so nothing is stuck saying "converting" forever. The
submitter sees the failure and can retry a URL submission or re-upload a file. Published songs and
reviews are untouched.
---
## Backups
`./storage` holds everything — audio, avatars, and `levyraati.db`.
**Do not just copy the database file while the app is running.** WAL mode means recent writes live
in `levyraati.db-wal`, and a bare copy can miss them or catch a torn state. Ask SQLite for a
consistent snapshot instead — it is safe against a live, writing database:
```sh
cd /srv/levyraati
docker compose exec app sqlite3 /storage/levyraati.db ".backup '/storage/tmp/backup.db'"
gzip -c storage/tmp/backup.db > /backups/levyraati-$(date +%F).db.gz
rm storage/tmp/backup.db
tar czf /backups/levyraati-audio-$(date +%F).tar.gz -C storage audio avatars
```
`storage/tmp/` is in-flight conversions and is safe to skip; it is cleared at startup anyway.
A daily cron of those four lines is a complete backup strategy for this app.
### Restoring
```sh
docker compose down
gunzip -c /backups/levyraati-2026-08-02.db.gz > storage/levyraati.db
rm -f storage/levyraati.db-wal storage/levyraati.db-shm # stale sidecars of the old file
tar xzf /backups/levyraati-audio-2026-08-02.tar.gz -C storage
docker compose up -d
```
Deleting the `-wal` and `-shm` files matters: left behind, they belong to the database you just
replaced, and SQLite will try to apply them to the restored one.
Audio and rows are backed up separately but must be restored together — a song row whose `.ogg` is
missing gives a broken player, and an orphan `.ogg` is invisible to everyone.
---
## Operations
### Logs
```sh
docker compose logs -f app
```
JSON to stdout, nothing else. Every line carries a `ctx` field (`startup`, `auth`, `songs`,
`submissions`, `invites`, `reports`) to filter on.
Two startup warnings are worth reading rather than skipping: `submissions interrupted by restart`
says the sweep cleaned up after a restart, and `failed submissions present` is often the first sign
that yt-dlp has gone stale.
### yt-dlp goes stale
yt-dlp rots against YouTube — routine maintenance, not an incident. It comes from Alpine's community
repository in the image, so **the fix is a rebuild**, which means publishing a new image rather than
anything on the server. Rebuild monthly. Failures show the yt-dlp error to the submitter, so members
usually notice before you read a log.
### Database shell
```sh
docker compose exec app sqlite3 /storage/levyraati.db
```
Writes here are unaudited and unvalidated — the schema holds the constraints, but the app's rules
(the review window, the reveal rule, the lock) are in Go. Prefer the admin panel.
### Disk
Audio is Opus at 96 kbps: roughly 23 MB per song, so a hundred songs is a few hundred megabytes.
`storage/tmp/` briefly holds a 50 MB upload plus its converted copy per in-flight submission,
bounded by the two conversion slots.
---
## Troubleshooting
| Symptom | Cause |
|---|---|
| Container exits immediately on a first start | `ADMIN_EMAIL` or `ADMIN_PASSWORD` unset on an empty database. The log says so; a site nobody can log into is worse than one that will not boot |
| `set IMAGE in .env` | Compose has no image to run; `IMAGE` is required and unset |
| `/healthz` says `ok dev` | The image was built without `--build-arg VERSION`, so what is deployed cannot be identified |
| Login never sticks | Plain HTTP with `SECURE_COOKIES=true`. Terminate TLS, or set it `false` for a local test |
| Uploads fail near 50 MB | The reverse proxy's body limit, not the app's |
| Invite links are relative | `PUBLIC_URL` unset |
| Everything 500s after a restore | `-wal`/`-shm` sidecars from the replaced database were left in place |
| Submissions all fail at download | yt-dlp is stale, or YouTube is refusing this server's IP; rebuild and publish the image first. `docker compose logs app \| grep '"stage":"download"'` shows yt-dlp's own stderr under `detail` |
| A submitter reports a *virhekoodi* | `docker compose logs app \| grep <code>` — one line, with the stage, the submission id, the URL and the tool's stderr |
| `/admin` returns 404 while logged in | That account has no `is_admin`. Set it in the database; nothing in the UI grants it |
| Setting `ADMIN_PASSWORD` again changes nothing | Seeding only fires on an empty `users` table. Reset the hash in the database instead |

A signed-in member who is not an admin gets **404, not 403**: the admin pages are none of their
business, and "forbidden" confirms there is something to be forbidden from. Everything else — the
session cookie, `SameSite` CSRF protection, the login rate limiter, ban-drops-sessions — is reused
rather than reimplemented, which is the whole point of the flag.
No bcrypt here: hashing protects *stored* passwords against a database leak, and this one lives in
the env file already. The constant-time compare is the part that
matters. **Fatal at startup if `ADMIN_PASSWORD` is unset** — an admin panel that silently opens is
worse than one that will not boot.
```go
// One listener. /admin is a route on the member mux, gated per-route.
log.Fatal(http.ListenAndServe(":8080", a.withMember(a.memberMux())))

// or the reverse proxy. A separate binary would need its own deploy and would race the
// startup migrations; it buys nothing else.

log.Fatal(http.ListenAndServe(":8080", memberMux))
```
**Bootstrap:** registration needs an invite and invites are minted from `/admin`, so an empty
database cannot grow a first user on its own. `seedAdmin` breaks the circle exactly once — on an
empty `users` table it creates account number one from `ADMIN_EMAIL` / `ADMIN_PASSWORD` and sets
`is_admin`. Against a populated database it does nothing, which is what makes it safe to leave in
the boot sequence. **Fatal at startup if those are unset on an empty database** — a site nobody can
log into is worse than one that will not boot.
**Bootstrap:** the admin logs in with the env credentials and mints the first invite. That is the
entire first-launch story. Losing the password is an edit to `.env` and a restart.
**Routes:** `GET /admin` dashboard, `POST /admin/invites`, `POST /admin/users/{id}/password`,
`POST /admin/users/{id}/ban`, `POST /admin/songs/{id}/delete`, `GET /admin/reports`,
`POST /admin/reports/{id}/resolve`. There is no `/admin/audio/{id}`: an admin is a member, so
`GET /audio/{id}` already works for them.
**Routes** (all on the loopback listener): `GET /admin` dashboard, `POST /admin/invites`,
`POST /admin/users/{id}/password`, `POST /admin/users/{id}/ban`, `POST /admin/songs/{id}/delete`,
`GET /admin/reports`, `POST /admin/reports/{id}/resolve`, and `GET /admin/audio/{id}` — moderating a
complaint means listening to the song, and a separate audio route avoids branching auth inside the
member handler.
**Ban** is a reversible toggle. It refuses login and deletes the member's sessions immediately.
Their songs and reviews stay, keep counting in the stats, and keep their name on them: a ban ends
participation, it does not rewrite history. An admin cannot ban *themselves* — the sessions would go
with it and nothing would be left to undo it.
