chore: agenternes arbejdstræer hører ikke i repoet

Et `git add -A` fangede .claude/worktrees/ som et indlejret repo. Det er en
agents arbejdskopi og skal ingen steder.

+# Mailboxes
+
+Star a mail and it becomes a task.
+
+This is the other direction from [mail to task](mail.md): instead of forwarding
+something, Verdande reads a mailbox you connect and makes a task out of anything
+you have flagged. Nothing else in the mailbox is touched, and nothing is ever
+sent.
+
+Each mailbox belongs to the person who connected it. Two people on one instance
+connect their own and see only their own — there is no shared inbox and no
+administrator who can read yours.
+
+## Gmail
+
+**Settings → Integrations → Gmail → Connect.**
+
+Gmail needs an OAuth client, which is the instance's registration with Google
+rather than anybody's account — see [Configuration](configuration.md#gmail).
+Once it is set up, each person connects their own mailbox through it.
+
+Choose what makes a task:
+
+| Trigger | What it reads |
+|---|---|
+| Starred | Anything you have starred |
+| Label | Anything carrying a label you name |
+
+!!! note "The app stays Internal if your client is Internal"
+    An OAuth client registered as *Internal* in a Google Workspace can only be
+    used by accounts in that workspace. A personal `@gmail.com` address will be
+    refused with `org_internal`, and that is the client working as configured.
+    Switching to *External* means refresh tokens that expire every seven days
+    until Google has verified the app — for one personal account, forwarding to
+    your [mail-to-task address](mail.md) is the shorter road.
+
+## iCloud, Fastmail and anything else over IMAP
+
+**Settings → Integrations → Mailboxes → Add a mailbox.**
+
+You need three things:
+
+| Field | Example |
+|---|---|
+| IMAP server | `imap.mail.me.com:993` |
+| Username | your address |
+| App password | not your ordinary password — see below |
+
+The connection is tested before it is saved. A mailbox that cannot be read is
+refused while you are still looking at the form, rather than accepted and then
+failing quietly every ten minutes.
+
+Flag a message — the flag, not unread — and it becomes a task on the next sweep.
+Unread is a state you are still using yourself, and a sync that consumed it would
+be taking something away.
+
+### App passwords
+
+Every host worth naming issues a separate password for applications, which you
+can withdraw on its own without changing the one you sign in with. Use that.
+
+- **iCloud** — [appleid.apple.com](https://appleid.apple.com) → Sign-In and
+  Security → App-Specific Passwords
+- **Fastmail** — Settings → Privacy & Security → Integrations → New app password
+
+The password is [encrypted at rest](configuration.md#secrets), and it is never
+returned by the API once saved.
+
+### Office 365 does not work here
+
+Microsoft has closed IMAP to passwords; it wants its own OAuth flow. There is no
+app password that will get you in, and a mailbox pointed at `outlook.office365.com`
+will be refused. Forward to your [mail-to-task address](mail.md) instead.
+
+## How often
+
+Every ten minutes, in the background. **Fetch now** does it immediately, which is
+for when you have just connected something and want to see it work.
+
+A run reads at most twenty-five messages, so a mailbox with years of flagged mail
+in it fills up over several sweeps rather than in one.
+
+## Disconnecting
+
+**Disconnect** on the mailbox. The tasks it made stay — they are your work now,
+not the mailbox's. Nothing is read after that, and the stored credential is
+deleted rather than merely disabled.

-Press ++q++ to jump to the quick-add box from anywhere, ++t++ for Today, ++u++ for
-Upcoming, ++cmd+k++ to search, and ++question++ for the full list.
+There is no shortcut to remember. Press a letter anywhere in the app and you are
+writing a task, with the letter you pressed already in the field. The thought does
+not have to survive a journey to find somewhere to put it.
+
+It only fires when nothing else has focus — a key pressed at a field, a button or
+a link belongs to that thing.
+
+Under the field is a line saying what the parser reads: `#` project, `/` section,
+`@` label, `p1` priority, and an example date. It appears while you are typing,
+which is the one moment a placeholder cannot help you.
+
+++cmd+k++ opens the palette — search, and navigation to anywhere in the app.

+!!! note "The single letters used to navigate"
+    ++t++ for Today and ++u++ for Upcoming are gone. One keyboard cannot both
+    spell *tal med Anders* and jump to Today on the same ++t++, and capturing is

+# Signing in
+
+Three ways in, and you can have all of them at once.
+
+## A password
+
+What the first account is created with. Nothing is emailed, nothing is registered
+anywhere: the first person to open a fresh instance creates the administrator
+account, and after that people arrive by invite link.
+
+## A code on top of it
+
+**Settings → Account → Two-factor.** An ordinary TOTP secret — any authenticator
+app reads the QR code. Once it is on, the password alone is not enough.
+
+Recovery codes are shown once, when you turn it on. They are the way back if the
+phone is gone, and they are not shown again.
+
+## A passkey
+
+**Settings → Account → Passkeys → Add a passkey.**
+
+A key on a device instead of a secret in your head. The private half never leaves
+the device — a phone's secure element, a laptop's keychain, a hardware key — and
+the signature is bound to the address it was made for, so a convincing copy of the
+sign-in page at a different address gets nothing.
+
+Give each one a name you will recognise later. *min bærbare* is what makes a list
+of keys reviewable, and a list nobody can read is a list nobody revokes from.
+
+Passkeys need the address in `VERDANDE_BASE_URL` to be a hostname. Browsers refuse
+to make one for a bare IP address, so an instance reached at `http://192.168.1.10:8080`
+will show the passkey section as unavailable rather than failing at the moment
+somebody tries.
+
+!!! note "One is enough, two is better"
+    Lose the only device holding your only passkey and you are back to the
+    password. Keep the password, or register a second key — a phone as well as a
+    laptop.

+-- rewrites the scope name on conflict — adding IMAP beside Gmail there would have
+-- deleted the Gmail connection without saying so. Migration 0011 warns about this
+-- in as many words, and the warning was nearly walked into a second time.
+--
+-- The shape is wrong for the thing anyway. A person has mailboxes, plural: a work
+-- Gmail and a private iCloud is the ordinary case, not the exotic one. A row each
+-- says that. It also answers the question that prompted this — every mailbox
+-- belongs to a user, so two people on the same instance connect their own and see
+-- only their own. The one piece that stays instance-wide is the Google OAuth
+-- client, which is a single registration everybody signs in through, and that is
+-- correct: it is the app, not the account.
+--
+-- `kind` rather than two tables. What differs is how the credential is obtained —
+-- OAuth for Gmail, a password for IMAP — and what differs is a nullable column,
+-- not a schema. What is the same is everything the sync loop touches: which
+-- mailbox, how far it has read, when it last ran.
+--

+"""Apple Noter → Markdown, med formateringen i behold.
+
+Den første udgave af det her brugte `textutil -convert txt`, som er hurtigt at
+skrive og smider alt væk: overskrifter, fed, monospace, lister. Ti prøvenoter
+viste hvad det koster — en note er ikke kun sine ord, den er også hvordan de er
+sat op, og et referat med overskrifter er ikke det samme referat som en klump.
+
+Apple Noter er HTML indeni, og HTML kan læses. Kortet er lille, fordi Noter selv
+bruger et lille sæt:
+
+    <h1> <h2> <h3>   overskrifter        →  # ## ###
+    <b> <i> <u>      fremhævning         →  ** * <u>
+    <tt>             monospace           →  ```-blok
+    <ul><li>         punktliste          →  -
+    <ol><li>         nummereret          →  1.
+    <div>            en linje            →  linjeskift
+    <br>             en tom linje        →  tom linje
+
+Kører på din egen maskine og sender ingenting nogen steder.
