Go, Postgres, `html/template`, HTMX + Alpine. Audio is converted with ffmpeg and downloaded with
yt-dlp. One binary, one origin — there is no separate frontend to deploy.
Go dependencies: `modernc.org/sqlite` and `golang.org/x/crypto`. The SQLite driver is pure Go, so the
build stays `CGO_ENABLED=0`. No Node, no npm, no bundler.
Go dependencies: `pgx/v5` and `golang.org/x/crypto`. No Node, no npm, no bundler.
## Running it
```sh
cp .env.example .env # then edit — set ADMIN_EMAIL and ADMIN_PASSWORD before the first start
cp .env.example .env # then edit — ADMIN_PASSWORD has no default and the app won't start without it
docker compose up -d

Migrations apply themselves at startup, before the server accepts connections. On an empty database
the first launch creates one account from `ADMIN_EMAIL` / `ADMIN_PASSWORD` and marks it admin; log
in as that account and mint invites for everyone else. The two variables are read only while the
`users` table is empty, so once that account exists they do nothing and can leave the environment.

### Configuration
| Variable | Default | Notes |
|---|---|---|
| `DB_PATH` | `$STORAGE_DIR/levyraati.db` | The SQLite file. Created on first start |
| `ADMIN_EMAIL` | — | Login address of the first account. Required on an empty database, ignored afterwards |
| `ADMIN_PASSWORD` | — | Password for that account. Required on an empty database, ignored afterwards |
| `ADMIN_NAME` | `Ylläpito` | Display name for that account |
| `ADDR` | `:8080` | The only listener |
| `POSTGRES_PASSWORD` | — | **Required by Compose.** Used to build `DATABASE_URL` for the app |
| `DATABASE_URL` | — | `postgres://user:pass@postgres:5432/levyraati` |
| `ADMIN_USER` | `admin` | Admin panel username |
| `ADMIN_PASSWORD` | — | **Required.** No default; the app refuses to start without it |
| `ADDR` | `:8080` | Member-facing listener |
| `ADMIN_ADDR` | `127.0.0.1:8081` | Admin listener. Keep it on loopback. Under Compose it binds `:8081` inside the container and is published only to the host's loopback |
| `STORAGE_DIR` | `./storage` | Audio, avatars, in-flight conversions |
| `SECURE_COOKIES` | `true` | Set `false` for local development over plain HTTP |
| `PUBLIC_URL` | — | Public address of the site, e.g. `https://levyraati.example.com`. Used to build invite links on the admin page; unset gives relative links |
| `PUBLIC_URL` | — | Public address of the member site, e.g. `https://levyraati.example.com`. Used to build invite links in the admin panel; unset gives relative links |
### Local development
```sh
export ADMIN_EMAIL=[email protected] ADMIN_PASSWORD=dev SECURE_COOKIES=false
go run ./src

```
The package lives in `src/`, together with the `templates/`, `static/` and `migrations/` it embeds —
`//go:embed` cannot reach outside its own directory, so the assets live beside the code that reads
them. `storage/` stays at the root, since it is runtime data rather than source.
Requires Go 1.24+, plus `ffmpeg`, `ffprobe`, and `yt-dlp` on `PATH`.
Requires Go 1.27+, plus `ffmpeg`, `ffprobe`, and `yt-dlp` on `PATH`. There is nothing to start first:
the database is a file under `./storage`, created on the first run.
Tests get a fresh database file in a temp directory each, so they need no setup and touch nothing.
`make` is everything that has to pass before a commit — formatting, `go vet`, and the tests:
Tests that need a database are skipped unless `TEST_DATABASE_URL` points at a throwaway one — the
migration test drops and recreates the `public` schema, so never point it at anything you care about.
```sh
make # gofmt -l, go vet, go test
make test # just the tests
go test ./...
```
Templates, stylesheet, and migrations are embedded with `embed.FS`, so a rebuild is needed to see
template changes. `make run` is the loop.
template changes. `go build && ./levyraati` is the loop.
## 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.

### Backups
`./storage` holds everything: audio files, avatars, and `levyraati.db`. It is a bind mount, so a copy
of that one directory is the whole backup. `storage/tmp/` is in-flight conversions and is safe to
skip; it's cleared on startup anyway.
Two paths hold everything:
Copying the file while the app is running is not a backup — WAL means the latest writes live in a
sidecar file. Ask SQLite for a consistent snapshot instead:
- `./pgdata` — the database. Postgres 18 stores it under a version subdirectory (`18/docker`), so
the mount is `/var/lib/postgresql`, not `/var/lib/postgresql/data`
- `./storage` — audio files and avatars
Both are bind mounts. `storage/tmp/` is in-flight conversions and is safe to skip; it's cleared on
startup anyway.
```sh
docker compose exec app sqlite3 /storage/levyraati.db ".backup '/storage/tmp/backup.db'"
gzip -c storage/tmp/backup.db > backup-$(date +%F).db.gz && rm storage/tmp/backup.db
docker compose exec postgres pg_dump -U levyraati levyraati | gzip > backup-$(date +%F).sql.gz
```
### Database shell
```sh
docker compose exec app sqlite3 /storage/levyraati.db
docker compose exec postgres psql -U levyraati levyraati
```
## 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.

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.

confirms.** Costs a `submissions` table, buys a `songs` table where every row is a real song and
no query filters on readiness.

starting at 1, for the second attempt at a release. The string lives in a git tag and reaches
the binary through `-ldflags`, so no file in the repo has to be bumped and a local build
honestly reports `dev`. It surfaces in the footer, the startup log and `/healthz`.
45. **Lyrics are suggested at submission, and stay editable forever.** Four decisions in one, taken
2026-07-31 while scoping the feature in [later.md](./later.md):
- **Suggested, never imposed.** The worker attempts one LRCLIB lookup after conversion, and the
waiting page carries a *Hae sanoitukset* button that re-queries with whatever title and artist
are currently typed. The button exists because our metadata comes from ID3 tags and YouTube
uploaders, so the automatic attempt misses exactly the songs with messy names — and would look
broken rather than absent. Neither path overwrites text the submitter has typed.
- **Lyrics live on the submission, not just the song**, and are copied across at publish, because
they are part of preparing a song rather than something bolted on afterwards.
- **No migration 002.** Nothing has launched, so the column goes into `001_init.sql` and the
database is recreated. The schema has no legacy to respect until there is data worth keeping.
- **The lock does not cover lyrics.** It exists so the thing people reviewed stops changing under
them, and nobody reviewed the lyrics — the rule is now *the lock freezes what the song claims
to be; lyrics are an attachment to it.* This also allows pasting lyrics for an old song, which
is when the feature is worth most.
The coverage assumption that shaped the earlier sketch was wrong and is corrected in `later.md`:
LRCLIB has synced lyrics for a good share of Finnish rock, not almost none.
46. **SQLite instead of Postgres — this reverses entries 1 and 3** (2026-08-02). Ten members and a
handful of songs a week never needed a database server, and the server was the last thing making
this a two-container deployment. `modernc.org/sqlite` is pure Go, so `CGO_ENABLED=0` survives and
the dependency count does not change: `pgx` out, `sqlite` in. What it buys: one container, one
bind mount that is the entire backup, no `pgdata`, no healthcheck-gated `depends_on`, no startup
retry loop, and tests that run anywhere instead of skipping without `TEST_DATABASE_URL`.
The port was smaller than expected, because the driver matches `$1`-style placeholders against
argument ordinals exactly as pgx does — so no query needed rewriting for parameters. What did
change:
- **`timestamptz` → `timestamp` holding UTC `YYYY-MM-DD HH:MM:SS`.** The declared type is what
makes the driver return `time.Time`; the fixed-width UTC string is what makes `order by
created_at` and `expires_at > datetime('now')` mean what they say. `_time_format=datetime` and
`_timezone=UTC` on the DSN make Go write exactly the shape `datetime('now')` produces, so the
two sources of a timestamp are comparable.
- **`interval` has no equivalent.** `sessions.idle_ttl` is seconds as an integer, and the review
edit window travels as a SQLite date modifier string (`-1800 seconds`).
- **No `stddev_pop`.** The divisive and unified boards use the population formula written out,
guarded with `max(0.0, …)` because floating-point cancellation returns a tiny negative when
every score is identical, and `sqrt` of that is null.
- **`foreign_keys` is off by default in SQLite**, so every `on delete cascade` in the schema is
decoration without the pragma. It is set on the DSN alongside WAL, `busy_timeout` and
`_txlock=immediate`.
Taken while there was still no data: the tables were recreated rather than converted, same as
entry 45. What would reverse this: enough concurrent writers that one writer is a real limit, or
wanting the database on a different box from the audio files.

# Deployment
How Levyraati gets onto a server and how it is changed once it is there. Configuration variables are
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.
```yaml
services:
app:
# Registry included. Pin a release tag, never :latest — a restart must not quietly change the
# running version. Kept in .env so this file carries no host of yours.
image: ${IMAGE:?set IMAGE in .env}
environment:
# Only read while the users table is empty: they create the first account and are ignored
# from then on. Safe to remove once that account exists.
ADMIN_EMAIL: ${ADMIN_EMAIL:-}
ADMIN_PASSWORD: ${ADMIN_PASSWORD:-}
ADMIN_NAME: ${ADMIN_NAME:-Ylläpito}
ADDR: ":8080"
SECURE_COOKIES: ${SECURE_COOKIES:-true}
PUBLIC_URL: ${PUBLIC_URL:-}
# The SQLite file sits in here beside the audio, so this one mount is the whole backup.
volumes:
- ./storage:/storage
ports:
- "8080:8080"
restart: unless-stopped
```
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 2–3 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; rebuild and publish the image |
| `/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 |

## Lyrics with scaled autoscroll

Fetch lyrics and scroll them in time with the audio.
**Coverage, measured 2026-07-31** rather than assumed. An earlier version of this page guessed
LRCLIB would miss nearly all Finnish music. It does not:
| Search | Results | With `syncedLyrics` |
|---|---|---|
| Nightwish | 20 | 20 |
| Eppu Normaali | 20 | 13 |
| CMX | 15 | 12 |
| Popeda | 20 | 8 |
**LRCLIB** (`lrclib.net`) needs no API key. `/api/get` matches on artist, track and duration within
±2 s and returns `syncedLyrics` — real LRC with `[mm:ss.xx]` per line — alongside `plainLyrics`;
`/api/search?q=` is the looser fallback. Go's side is `net/http` and `encoding/json`, so the
dependency budget survives, and it is treated exactly like ffmpeg and yt-dlp: a timeout, allowed to
fail, never blocking anything.
**Where it happens: at submission, as a suggestion.**
- The worker attempts one automatic lookup after conversion, using whatever metadata exists.
- The waiting page has a **Hae sanoitukset** button that re-queries with whatever is currently typed
in the title and artist fields. That is the answer for messy tags — `Sentenced Noose` from a
YouTube upload will not match until the submitter fixes it, and the automatic attempt would
otherwise just look broken.
- Neither ever overwrites text the submitter has typed. They can accept the suggestion, edit it, or
leave the field empty.
**Storage:** one nullable `lyrics text` column on both `submissions` and `songs`, copied across at
publish. LRC or plain is told apart by whether the first line starts with `[`, so no second column
and no flag. **Nothing has launched, so this goes into `001_init.sql` rather than a migration 002.**
**Lyrics stay editable after the song locks** — the lock exists so the thing people reviewed stops
changing, and nobody reviewed the lyrics. It also means someone can paste them for an old song a
year later, which is when this feature is most useful.
**Playback:**
- **Synced hit** → highlight the current line properly, driven by the transport's `timeupdate`.
- **Plain hit or manual paste** → distribute lines evenly across `duration_seconds` and scroll the
block *continuously without highlighting a line*. Highlighting makes every second of drift read as
a bug, and drift is guaranteed — intros and outros alone break a uniform mapping.
- **LRCLIB** (`lrclib.net`) is a community database with no API key, and its responses include
`syncedLyrics` — real LRC with `[mm:ss.xx]` per-line timestamps — alongside `plainLyrics`. Query by
track, artist and duration, all of which are already on the song row. So a decent share of songs
need no faked timing at all.
- **Synced hit** → highlight the current line properly. **Plain hit or manual paste** → distribute
lines evenly across `duration_seconds` and scroll the block *continuously without highlighting a
line*. Highlighting makes every second of drift read as a bug, and drift is guaranteed — intros and
outros alone break a uniform mapping.
- The Web Animations API does the whole thing including seeking: build the scroll animation with
`duration_seconds`, `pause()` it, and bind `play`/`pause`/`seeked` on the audio element. No timers,
no drift accumulation.
- **Leave a nudge knob** — a ±10 s offset slider, remembered per song in `localStorage`. Uniform
distribution models a song no real song obeys, and one drag while listening beats any heuristic.
**Still open:** where the panel lives on the song page. That page's job is now *listen and write*,
and a scrolling lyrics panel competes with the review textarea for both space and attention — a
collapsed panel under the player is the starting guess, not a decision.
Copyright posture is the same as the YouTube note: private app, ten people, written down
deliberately.
- Storage: one nullable `lyrics text` column. LRC or plain — tell them apart by whether the first
line starts with `[`, so no second column and no flag. Fetched best-effort in the publish worker.
- **Add a paste box to the submitter's edit form.** The genre list contains *Finnish*,
*Experimental* and *Just Plain Weird*; LRCLIB will miss nearly all of it, and for those songs the
textarea is the entire feature.
- Copyright posture is the same as the YouTube note: private app, ten people, written down

## 6. Admin
**An admin is a member with `is_admin` set.** One boolean column on `users`, no role enum. They
submit and review like anyone else and appear in every list and leaderboard, so no query has to
exclude them. The admin UI is Finnish, like everything else.
**The admin is not a user.** They never submit, never review, and never see the member-facing site.
No `role` column, no admin row, no admin session, no admin login page, no first-launch seeding — and
no query anywhere has to exclude the admin from a list, a leaderboard, or an aggregate. The admin UI
is Finnish, like everything else.
```go
// ponytail: one flag, no roles. A moderator tier is a second column on the day someone needs to
// resolve reports without also being able to reset passwords.
func (a *app) requireAdmin(next http.HandlerFunc) http.HandlerFunc {
return func(w http.ResponseWriter, r *http.Request) {
m := memberFrom(r.Context())
if m == nil {
http.Redirect(w, r, "/login", http.StatusSeeOther)
// ponytail: Basic Auth, no admin session, no admin row. Ceiling: one admin, no logout
// (close the browser). Add a cookie session if a second admin ever needs one.
func requireAdmin(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
u, p, ok := r.BasicAuth()
if !ok || subtle.ConstantTimeCompare([]byte(u), []byte(adminUser)) != 1 ||

}
```
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 next to the Postgres password 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())))
// ponytail: two listeners, one process. Admin is loopback-only — reach it over an SSH tunnel
// or the reverse proxy. A separate binary would need its own deploy and would race the
// startup migrations; it buys nothing else.
go func() { log.Fatal(http.ListenAndServe("127.0.0.1:8081", requireAdmin(adminMux))) }()
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.

`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

with it and nothing would be left to undo it.
