The list of notes and the note being written are one screen now, two
panes: the notes on the left, the open one on the right, side by side
where there is room and one at a time on a phone, where the back button
returns to the list.
The search box moved into the top of that list, and its results *are*
the list — searching is a way of finding a note, not a separate place to
be, and a tab for it was a tab too many. Emptying the box brings the
whole list back. Opening a hit opens that day at the lesson that
matched, rather than at the top of a day with six of them.
A row has to say what the note holds, so the listing carries it: the
subjects a day covers, how many lessons, and the first line actually
written in it. One request for the whole list rather than one per note.
`plainText` is now one rule in one place for wherever a note is shown
rather than edited — the search snippet and the list row both went
through their own half-copy of it, and the row's copy rendered a table
as `| | |` and left `_Fazit_` wearing its markers. It strips one leading
marker, not each in turn, because `## 1. Deutsch` keeps its lesson
number and the list rule was eating it.
Driven in Firefox at both widths: the list, the search, opening a hit,
the jump to the lesson, and the phone's list-then-note. 390 unit tests,
116/117 smoke.

Two things found by using this on real notes.
**The paste.** Copying out of Apple Notes put most of the note on the
floor. WebKit wraps a copied selection in a single span carrying the
computed style of everything in it — `font-weight: 700` included — with
the real blocks nested inside. The serializer read that span as inline,
so every line collapsed into one paragraph and every word came out bold;
switching to the Markdown view then showed what little had survived,
which is what "most of the text was gone" was. And because the boldness
came from a foreign span's style rather than a tag, the bold button
could not remove it.
The rule now is that an element holding blocks is a block whatever its
tag, and that a container's style is not emphasis — only a span wrapping
a single run of text is. A paste this editor cannot read at all (some
engines withhold the clipboard from the event) is tidied afterwards
instead, but only if something actually arrived, so an empty paste still
costs nothing.
**The search.** A Suche tab over the user's own notes, reading the files
rather than the index: notes reach the index only on a full crawl, so a
lesson written this morning would not be findable this morning, which is
most of what anyone searches their own notes for. A result names the
lesson it matched in, not the day, for the same reason the index indexes
day notes per section. Tapping one opens that day in the editor.
Driven in Firefox against the real app with a proxied session: the
paste, six switches between the two views, bold and unbold on pasted
text, the search, and opening a result. 386 unit tests, 114/115 smoke.

`console.log` in JXA writes to standard error, not standard output, so
`> notes.ndjson` produced an empty file while every note scrolled past
on the terminal. Both streams now go through NSFileHandle, which is the
only way to be sure which one you are on; the comment says so, because
the next person will reach for console.log too.
`--folder` was a substring match applied after each note's body had
already been read. It now matches a whole path segment — `Schule` takes
Schule and everything under it and leaves Musikschule alone — and is
checked before the body, which is the one expensive property and is what
makes a large library take minutes.
The path is recorded relative to the folder asked for, because the
import reads its last segment as the subject: `Schule/Deutsch` has to
arrive as `Deutsch`, and a note loose in `Schule` has to arrive with no
subject at all rather than one called "Schule".
Not run: this needs a Mac with Notes, and there is none here. The JXA
stream behaviour is the documented one and the folder logic is plain
string work, but the script itself is still unexercised.
The editor was a textarea holding raw Markdown, which is the wrong thing
to hand someone taking notes during a lesson: nobody types `##` and `**`
while a teacher is talking. It now shows the note formatted and puts a
toolbar above it — headings, bold, lists, tick boxes, quotes, links,
tables — while the file on disk stays exactly what it was, because that
is what the indexer reads and what outlives this app.
`markdown.js` is the whole translation: `markdownToHtml` on the way in,
`markdownFromDom` on the way out. The property that matters is that the
round trip settles — one pass may tidy a note, a second must change
nothing — because these notes are the only record of what was said in
the room and there is nothing to restore a lossy save from. `editor.js`
checks exactly that before opening a note formatted, and a note it
cannot hold unchanged opens in the Markdown view and says so instead of
being quietly reduced.
No editor library: the content security policy allows no outside script
and the app has no bundler, so this is `contenteditable` and
`execCommand` with a tolerant serializer behind it — an element it does
not model keeps its words and loses its tag. Pasted HTML is converted to
Markdown before it reaches the document, which is the one place where
sanitising and formatting are the same operation.
Tested against `test/mini-dom.ts`, sixty lines of read-only DOM, rather
than a headless browser or a DOM dependency; the toolbar itself was
driven by hand in Firefox. WebKit has still never run it.
The Dockerfile creates /data/mirror and /data/state with the right owner,
and the comment above it says exactly why: Docker initialises a new named
volume from the image directory, so a mount point the image does not have
lands root-owned and the unprivileged user gets EACCES on every write.
/data/notes was added to docker-compose.yml without being added here, so
every save on a fresh deployment would have failed that way — verified
both directions before fixing it.
docs/DEPLOY-NOTES.md is the runbook for putting this on a server that is
already running: publish, decide where the notes live *before* anything
writes one, set WEB_PASSWORD, verify, migrate, index. Plus rollback,
which is uneventful — no migration, and the old image simply ignores the
new settings and leaves the notes volume alone.
PI.md's backup table needed the bigger change. Everything else this
server stores is a copy of something upstream and a crawl rebuilds it;
the notes are not, and nothing can. They are now the one entry in that
table marked irreplaceable, and the EACCES row says to fix the volume's
ownership rather than delete it.

The notes existed but there was nowhere to write them: a CLI command on a
laptop, a tool call through Claude, or a file in a Docker volume. None of
those is reachable from a phone in a lesson, which is where notes are
actually taken.
So: `/app`, served only when WEB_PASSWORD is set. A login, the day's
notes, and a settings page for the Schulcloud token — the one surface
here meant for a person rather than a program.
The shape follows how the notes are written: one note per school day,
one `##` heading per lesson, prose and lists and tables beneath. That
turns out to be the design decision that matters, twice over.
First, it is what lets WebUntis earn its keep. Opening a day with no
note fills in that day's lessons — numbered, with times, teacher and
room, cancellations dropped and substitutions marked. Retyping the
timetable is exactly the work the second upstream exists to avoid, and
"Stunden ergänzen" tops up a note started before the day ended without
touching what is already written.
Second, it changes how notes are indexed. A day note is indexed per
lesson, not whole: search answers "my own note, Deutsch, 18.09.2026"
rather than "my own note, Friday", and `list_notes subject=Deutsch`
finds a day whose frontmatter names no subject at all. Indexed whole,
every hit would read as a weekday and "what did we do in Deutsch" would
match notes whose other five lessons were something else. `lessonHeading`
and `subjectFromHeading` are a loop — the app writes the heading, the
indexer reads the subject back out — and a test holds them to it.
Notes taken in a lesson cannot be retaken, so the editor is built
around not losing them: autosave, every keystroke mirrored to local
storage, a save when the phone locks, and a fallback to the local copy
when the request never arrives. A save that would overwrite a version
the editor never saw is refused and the choice handed back — the notes
folder is synced and open in more than one place, and a phone must not
silently win over a laptop. `replaceNote` is separate from `writeNote`
for that reason: never-overwrite is right for `add_note` and exactly
wrong for an editor.
WEB_PASSWORD is the first credential here a human types, so it is the
first that can be guessed: scrypt at startup, never stored or compared
in the clear, per-address rate limiting — which is not decoration, since
the scrypt cost is itself a denial-of-service vector without it. The
session is a signed HttpOnly SameSite=Strict cookie whose key is derived
from the password, so changing it logs everyone out and there is no
second secret to keep. It opens /api, because a session is the user, and
never /mcp, because nothing in a browser speaks MCP.
Also here, because the app made them matter: frontmatter now reads the
indented `- item` list form editors write, so an Obsidian vault
round-trips its tags; and a four-digit folder is a filing scheme, not a
subject, so `2026/` does not file a school year under one.
357 tests; 106/107 smoke against the local instance, the one failure
being the H5P service that instance does not run.

Schulcloud says what was uploaded and WebUntis says what was scheduled.
Neither says what was *taught* — which point the teacher laboured, which
example landed, what "will definitely come up". That lives in two places
this server could not reach: the notes the user takes in the lesson, and
WebUntis' class register.
Notes are a directory of Markdown files (NOTES_DIR), not a table. They
have to be writable from a phone in a classroom, readable when Postgres
is down, and outlive this project, and files are the only shape that is
all three — so the files are the truth and the index is a view of them,
the same split as file_texts and the mirror. list_notes and get_note read
disk, so they answer before the first crawl; search, what_changed and all
three German prompts read them alongside the Schulcloud material.
add_note writes one, and is the only thing in this server that writes
anything. That is not a hole in the read-only invariant but a different
store: it is bounded to NOTES_DIR by the same safeComponent/resolveWithin
pair that stops a hostile Schulcloud filename escaping the mirror, so a
note titled ../../.ssh/authorized_keys becomes a filename. Schulcloud and
WebUntis stay GET-only and allowlisted respectively. NOTES_READONLY
refuses writes outright.
Appending targets the *lesson*, not the title: "halt das auch noch fest"
mid-lesson carries a new title, and deriving the path from it would start
a second note every time, which is the one thing append exists to prevent.
Notes.app has no export — its bodies are compressed protobuf and the
iCloud copy is encrypted — so scripting the app is not the clumsy route
to the notes but the only one. scripts/export-apple-notes.js reads them
through AppleScript into one JSON object per line, and `schulcloud note
import` converts the HTML to Markdown, takes the Notes folder as the
subject and the *creation* date as the lesson's date. Attachments cannot
come across; a note that was a photo of the board imports as a line
saying so, because importing it empty would hide the loss.
The class register needed one API property to become cheap:
getLessonTopic2017 answers per *series*, not per period, so a term is
reconstructed by asking about the latest period of each lesson series and
merging back by id — a few dozen calls for a school year rather than one
per lesson. untis_lesson_topics now takes a subject as well as a period
id, and UNTIS_HISTORY_DAYS of register goes into the index under a kind
of its own, so "what did we actually do before the test" is searchable.
Sharing the snapshot rather than duplicating it caught one thing on the
way: the search tool's live path had to learn notes too, or fresh=true
would have quietly disagreed with the index.
305 tests; 88/89 smoke against the local instance, the one failure being
the H5P service that instance does not run. The live smoke could not be
retaken: that session has lapsed and needs a fresh jwt cookie.
