Kristian WindandClaude Opus 5 997dffe01c docs: skriv det, der blev bygget, og ret det, der ikke passer længere

To nye sider. Postkasser: at stjerne i Gmail eller flage i iCloud og Fastmail
bliver til opgaver, at hver postkasse hører til den, der forbandt den, at
app-kodeord er noget andet end ens rigtige, og at Office 365 ikke kan nås ad den
vej — sidstnævnte skrevet ned frem for at blive opdaget ved at prøve. Og at logge
ind: kodeord, totrinskode og passkeys, med hvorfor en passkey ikke kan laves på
en bar IP-adresse.

Konfigurationen manglede VERDANDE_SECRET_KEY, som er den, det koster mest ikke at
vide noget om: mister man nøglen, skal postkasserne forbindes forfra. Begrundelsen
står med — det er kopierne, ikke serveren, der er problemet, for de kan hentes
gennem fladen.

Og genvejsafsnittet i quick-add beskrev q, t og u, som ikke findes længere. En
dokumentation, der lover taster, der ikke gør noget, er værre end ingen: man
prøver, der sker intet, og så tror man appen er i stykker.

Bygget med --strict; alle krydshenvisninger rammer.

Configuration

Everything is an environment variable. There is no config file — a Rune has nowhere to put one that the operator would ever see.

Core

Variable	Default	What it does
`VERDANDE_BASE_URL`	`http://localhost:8080`	The public address. Invite links, password resets, calendar feeds and the mail-to-task address are all built from it.
`VERDANDE_ADDR`	`:8080`	Listen address.
`VERDANDE_DATA_DIR`	`/data`	Database, uploaded files and backups.
`VERDANDE_DEV`	`false`	Human-readable logs at debug level, and a relaxed origin check so a Vite dev server can connect. Never in production.

Sessions and links

Variable	Default	What it does
`VERDANDE_SESSION_TTL`	`720h`	How long a login lasts.
`VERDANDE_INVITE_TTL`	`168h`	How long an invite link stays valid.
`VERDANDE_RESET_TTL`	`1h`	How long a password-reset link stays valid.

Any Go duration: 720h, 30m, 45s.

Mail

Variable	Default	What it does
`VERDANDE_SMTP_HOST`	—	Blank disables outbound mail entirely.
`VERDANDE_SMTP_PORT`	`587`
`VERDANDE_SMTP_USER`	—
`VERDANDE_SMTP_PASS`	—
`VERDANDE_SMTP_FROM`	`verdande@localhost`	Sender address. Also decides the domain of the mail-to-task address.
`VERDANDE_SMTP_STARTTLS`	`true` unless port 465	Port 465 is TLS from the first byte; everything else negotiates.
`VERDANDE_SMTP_INSECURE`	`false`	Skip certificate verification. For a self-signed internal mail server, and nothing else.

!!! info "Running without a mail server" Perfectly supported. Invite links are shown in the app for you to send yourself, password resets are written to the log, and reminders arrive in the app and as Web Push rather than by email.

Gmail

Only needed if anyone will connect a mailbox. Register an OAuth client in Google Cloud (APIs & Services → Credentials → OAuth client ID → Web application) with the redirect URI https://your-address/oauth/gmail/callback, enable the Gmail API, and add the gmail.readonly scope.

Variable	What it does
`VERDANDE_GMAIL_CLIENT_ID`	The client id from Google Cloud.
`VERDANDE_GMAIL_CLIENT_SECRET`	The client secret.

One registration serves every user on the instance; each person authorises their own mailbox from Settings → Gmail. The redirect URI is derived from VERDANDE_BASE_URL, so it cannot drift out of step with what you registered.

Secrets

Variable	Default	What it does
`VERDANDE_SECRET_KEY`	—	Encrypts the mail tokens and mailbox passwords in the database. 32 bytes of base64.

Mail tokens and mailbox passwords are encrypted at rest, and the key does not live in the database. That is the whole point: backups can be downloaded through the interface, so a copy that ends up somewhere it should not would otherwise open your mail.

Leave the variable empty and verdande writes a key to secret.key in the data directory on first start, mode 0600. Backups are a VACUUM INTO of the database alone, so the key file is not in them.

Generate one yourself if you would rather keep it out of the volume entirely:

openssl rand -base64 32

!!! warning "Lose the key and the mailboxes must be reconnected" Nothing else is lost — tasks, projects, files and history are not encrypted — but a token that cannot be decrypted cannot be used, and there is no way back from a key that is gone. If you restore a database somewhere new, bring secret.key with it, or set VERDANDE_SECRET_KEY to the same value.

A database written before there was a key is read as it stands and encrypted the next time each value is written, so turning this on costs nobody a reconnection.

Update checks

Variable	Default	What it does
`VERDANDE_UPDATE_CHECK`	`false`	Ask GitHub whether a newer release exists.
`VERDANDE_PANEL_URL`	—	The Yggdrasil panel this instance runs under.
`VERDANDE_PANEL_TOKEN`	—	An API token from that panel, belonging to somebody with control of this server.
`VERDANDE_PANEL_SERVER_ID`	—	Which server to restart — the id in the panel's URL.

All three together let Settings → Notifications restart this instance, which is also how it picks up a new version: a container cannot replace its own image, so the panel recreates it and pulls :latest on the way. The request asks the panel for a scheduled restart rather than an immediate one — an immediate one is carried out while the request is still open, and stopping the container kills the very process waiting for the answer, so the panel never gets to the half that starts it again. Any one of the three alone does nothing, and the page names the ones that are missing.

The token is a panel credential with control over that server. Anybody who can read this environment can restart it — which is true of anybody with the host anyway — and it is never sent to a browser.

Off unless you turn it on. When on, verdande asks the public GitHub releases API at most every six hours and sends nothing about your instance — no identifier, no version, no count of anything. Only administrators are shown the result.

What is not configured here

AI providers are per-user, under settings in the app — see AI. One person's key is not the instance's key.

The VAPID keypair for Web Push is generated on first use and stored in the database. There is nothing to set.
