A ```typst (or ```typ) block is compiled by the typst crate into SVG and
shown as an image where it stands, so math, tables and figures can be
written in typst beside the markdown around them. It shows its source while
it is set, and the error typst gives, with the block's line, when it cannot
be.
Each block is a document of its own: its source is the only file in its
world and the fonts are typst-assets', inside the binary, so nothing is read
from disk or fetched — packages and images are refused. The page fits what
is on it, is transparent, and carries the theme's text colour. Answers are
cached by source, two blocks are laid out at a time off the async threads,
and comemo's memo is evicted after each compile.
A share page asks POST /api/share/{token}/typst, which takes the reader's
cookie and typesets only a block the shared document holds.
typst brings a palette crate whose AsRef impls on arrays made four
`kek.as_ref().into()` in the vault ambiguous; they deref instead.
The file pane decided what to show by MIME type, and uploads keep a
type only when it cannot execute, so a .md, a .json or a .pem arrived
as application/octet-stream and got "no preview". It now goes by name
first (preview.ts), and a file with a name it does not know has its
first 8 KiB looked at: no NUL bytes and valid UTF-8 means text.
- text and code: the first 256 KiB with line numbers, as before
- markdown: rendered through the same sanitiser as documents, with a
source toggle
- CSV/TSV: a table of the first 500 rows, quotes respected
- PDF: the browser's own viewer in a frame. Only a PDF is served
without the sandbox CSP (Chrome's viewer will not start under it),
with frame-ancestors 'self' and X-Frame-Options SAMEORIGIN; the app
CSP allows same-origin frames.
- certificates, keys, keystores: POST /api/nodes/{id}/inspect reads
PEM (chains, keys, requests, public keys), DER and PKCS#12 on the
server, in pure Rust, including the RC2/3DES keystores that
openssl -legacy and older keychains write. It answers with subject,
issuer, validity, key, names, usage and fingerprints, and pairs each
private key with its certificate by public key. A password is asked
for only when needed, used for that one answer and never stored;
no key material is ever sent back. Sealed files are read through the
vault, and only while it is open.
The tests read throwaway fixtures under src/routes/testdata, made with
the openssl commands listed beside them; .gitignore lets their .pem
files past a global *.pem rule.
The stored session used to hold the mailbox password, which on a
single-password account is the login password. It now holds the per-key
passphrases derived from it at login, which unlock the keys but cannot
log in, change the password or turn 2FA off. Login also checks them
against the account's keys, so a wrong mailbox password fails there
rather than at the first backup.
A session stored by an older build is upgraded on the next start: its
key salts are already known, so the passphrases derive locally and the
file is rewritten without the password.
Argon2id turns the vault password into a key that seals a random master
key; only the sealed copy is kept. Each file gets its own key, sealed
under the master key in its header with its media id, and its bytes are
AES-256-GCM STREAM records, so a swapped, cut or altered file refuses
to open. Uploads with ?encrypt=true are sealed as they stream in.
:vault, :unlock, :lock, :passwd, :encrypt, :decrypt and :upload! drive
it. The vault locks after WORKSPACE_VAULT_IDLE_MIN idle minutes, on
logout and on restart; while locked, sealed files answer 423, share
links never serve them, and :export! refuses rather than leave them out.
Sealing an existing file rewrites it under a new id and retires the old
one: the mirror deletes the plaintext from Proton Drive outright,
trash included, whatever WORKSPACE_BACKUP_PRUNE says, and drops it from
the readable files/ view. The mirror now compares on-disk sizes, so
sealed files are not re-hashed every run.
Add an in-process SFTP server (russh) backed directly by the nodes
table, so a space can be edited from nvim or synced with sshfs without
a separate filesystem mirror. Access is authenticated by public key
against a new ssh_keys table, managed via :sshkey in the app; the
feature stays off until WORKSPACE_SFTP_BIND is set.
The diary grows into a workspace: a flat list of dated entries becomes a
tree of spaces, and the app is renamed to match what it now is.
Spaces and nodes
One recursive `nodes` table replaces `entries`: a space is a root node,
and folders and documents nest under it without limit. Entries keep
their ids through the migration, so share tokens, media links and the
drafts in localStorage all still resolve.
Folder import
A folder or a zip is uploaded as a document tree. Markdown becomes
documents titled from their first heading, everything else becomes
media, and relative links between the imported files are rewritten to
the paths they landed at, so a set of cross-linked notes stays
navigable after the upload.
Boards
A kanban board per space, with the space as the board: lists, cards,
due dates and an optional link to a document. `diary` has none.
Mail
SMTP notifications through an outbox. A mail is enqueued under a key
naming the occurrence it belongs to, so a restart cannot resend and a
relay that refuses is retried with a widening backoff. Four kinds: the
diary reminder, cards due and overdue, a weekly digest, and logins
from a browser that has not been seen before or a burst of failures.
All of it is dormant until WORKSPACE_SMTP_URL is set.
Rename
Everything user-visible says workspace; everything that already exists
outside this repo keeps its name, because renaming it would break a
running deployment for tidiness alone: the database file, the docker
volume, the session cookie, the Proton device, the keyring entry and
the localStorage keys. Configuration reads WORKSPACE_* first and falls
back to DIARY_*, so the deployed .env keeps working untouched.
The data directory is the whole diary, and until now keeping a copy of it
was someone's manual job. The server can now register itself in Proton
Drive as a device — its own sync root, next to the desktop clients — and
keep that folder equal to DIARY_DATA_DIR, encrypted client-side by the
same Rust SDK the Linux client uses.
One interactive `narl-diary proton-login`, then nothing prompts again.
The stored session carries the tokens, the mailbox password (the key
chain is rebuilt from it on every start) and the account key salts, which
have to be captured at login: `core/v4/keys/salts` needs the `locked`
scope, and only a password-login token has it. Refresh tokens are
single-use, so every rotation is written back before it can be needed.
It lives as a 0600 file next to the database, on the same volume as the
data it protects; `--features keyring` puts it in the OS keyring instead,
for hosts that have a Secret Service.
The mirror is one-way and change-driven: writes mark the diary dirty and
it is mirrored once the writing stops, with an interval as the backstop —
an hour of writing is one backup, not sixty. `diary.db` goes up as a
VACUUM INTO snapshot, so it is a real point in time rather than a file
copied out from under a writer, and as a new revision each time, so
Proton keeps the older ones. Uploads are immutable, so they are written
once and skipped by size afterwards. Deletions do not propagate unless
asked: a backup that forgets on command is one accident away from being
no backup at all.
Identification follows Proton's third-party rules — an honest
`external-drive-narl_diary@<version>-alpha`, the disclosure printed
before any credential is asked for, and remembered folder uids instead of
walking the tree every run.

There was no way to get everything out — only one entry at a time, by
hand. A diary you cannot leave is not a diary you can trust.
The archive is entries/ as one markdown file per entry named by its day,
media/ with every embedded file under its real name, and a README. Media
links are rewritten to relative paths, so the entries render in any
markdown reader with no help from this application. Names are restricted
to characters that need no escaping inside a markdown link.
It is built on the blocking pool into a temporary file and streamed, so a
diary with photographs in it never has to fit in memory.
Single-user diary served as one Rust binary with the Svelte frontend
embedded.
- axum 0.8 + SQLite (sqlx), migrations run at startup
- stateless HMAC session cookie; credentials from .env, compared in
constant time
- FTS5 full-text search, user input rewritten into quoted prefix terms
- media uploads linked to entries by scanning bodies for /api/media/<id>,
which scopes share-token media access and entry deletion
- unguessable share links (192-bit token) serving a public read-only page
- vim keybindings via CodeMirror plus a modal browse layer and : command
line; disabled on touch devices
