Many teachers never use topics or boards; their material sits in the
course's file area, and the tools answered "0 files" for courses holding
dozens of worksheets — 21 of 26 courses on the live account. Persönliche,
Kurs-, Team- and Geteilte Dateien live in the legacy file store, not in
files-storage, and its service is not in the public ingress. The only way in
is the legacy client: HTML listings, and GET /files/signedurl for a
pre-signed download.
core/legacy-files.ts turns that into one path tree — /my, /courses/<course>,
/teams/<team>, /shared — resolving names that contain "/", ids anywhere in a
path, and wrong or ambiguous names with a message saying what is there. A
listing that does not parse throws; it never reads as an empty folder.
Some of the legacy client's GET routes write (GET /files/share/ mints a
share token), so getFileManagerPage allows only the listing routes, by
pattern. Signed URLs are fetched with no credentials and must be https.
- MCP: fs_list, fs_tree, fs_find and fs_read; get_course lists course files.
- CLI: schulcloud fs ls, tree, find and get, recursive and resumable.
- API: /api/fs/list, tree, find and file.
- Index: the crawl walks the file manager (INDEX_FILE_MANAGER, on by
default), so search covers the text inside those files and sync mirrors
them under <course>/Kurs-Dateien.
The local instance gains a fixture for all four areas. It needed a loopback,
so signed URLs open from the host, and a pre-created bucket, since MinIO
does not implement PutBucketCors.

Every area — courses, rooms, boards, topics, tasks, files, quizzes, teams,
groups, submissions, grades — was checked for data the instance has and the
tools did not show.
Grades and feedback. A teacher's /homework page is a different page from a
student's: grade and comment live in the grading form, one block per
submission, so a teacher account reported every graded submission as having
neither. parseTeacherGrading reads the form, and list_submissions can now
include the written feedback and who handed the work in.
Names. /api/v1 is partly served: courses, users and classes survive in the
deployment's ingress table, and users/{id} is the only route from an id to a
name. Submitters, file creators and course teachers resolve through it, and
degrade to "not visible to this account" where a student may not read them.
Courses, rooms and classes. get_course adds the description, teachers,
member count and weekly timetable from /api/v1/courses. list_classes is new.
get_room reports what the account may do — allowedOperations is an object of
booleans, not the list it was typed as — and applicants and invitation links
where it may manage them.
Board and topic content. Link descriptions, image alt text, drawing and
video-conference titles, the ids behind external tools and H5P content (the
only thing resembling a quiz), and what a deleted element used to be. Topic
Etherpad pads are read like board pads, and htmlToText keeps table columns
apart and drops template indentation.
Files. A scan with no text layer falls back to the preview endpoint, whose
width and outputFormat are undocumented enums, so Claude gets a picture of
the page; list_files reports counts and sizes. Teams stay documented as
unreadable at any API version; their files come later.
What the crawl missed. Tasks attached to topics (18 of 60 on the live
account), each course's own file area, and — behind INDEX_PERSONAL_FILES —
personal files and submissions with their grade comments, so search and
what_changed cover grading. A submission hit points at get_task.
The local instance's preview profile gets an ImageMagick policy that allows
the coders its 7.1.2 build needs; the image's own denies them all.
110 tests.

The account this was built against is in no rooms, so the whole space was
invisible and easy to dismiss as an empty endpoint. It is not empty in
general — the user had rooms until a teacher removed access — and the
UI's naming actively hides the distinction: the sidebar's *Kurse* entry
links to `/rooms/courses-overview` and lists courses, while *Räume* links
to `/rooms` and lists rooms. A url containing `/rooms` identifies neither.
list_rooms and get_room cover the latter. A room holds boards and nothing
else, so get_room lists boards for get_board (which already reports "in
room" from the board context) plus who else is in it. Room boards report
`isVisible`, which the course-page projection does not, so a draft is
named as a draft instead of being offered and then answering 403.
Rooms also go through the crawl, or they would have become the next
blind spot: their boards are indexed, searchable by both the index and
the live-crawl path, diffed by what_changed, and mirrored by the CLI
under the room's name. The board traversal and the snapshot matcher are
now shared between courses and rooms rather than duplicated, which also
fixed the live-crawl path silently not searching pad contents.
The CLI needed no new command — it is file-centric and inherits rooms
through the manifest — but `--course` now accepts a room id, and says so.
`kind` gains 'room'; the column is plain TEXT, so no migration. 112 tests.
Smoke: 42/42 and 44/44 local, 41/41 and 43/43 live.

Testing against a local instance turned up four things the server was
getting wrong, all of them invisible against the live account because the
data that exposes them had never been produced there.
`GET /lessons/{id}/tasks` returns a bare array, not the `{data,total}`
envelope every sibling endpoint uses, so `.data` was undefined and a
topic's tasks silently vanished. Its items also carry no id at all —
`LessonLinkedTaskResponse` has no id property — which leaves a
topic-attached task unidentifiable: it is not a task element on the
course page, and once past due it is in neither task list. So its
submission, and its grade, could not be reached by any route. That is 18
of 60 tasks on the real account, now reachable: the ids come off the
legacy topic page, where each task is linked as `/homework/{id}`.
The types said `id: string` and `status: TaskStatus` on something that
has neither, which is what let this stay quiet; `LessonLinkedTask` and
`ResolvedTask` now say what is actually there.
Collaborative text editor elements come back with `content: {}`, and the
tool said their contents were unavailable. They are available: the
content-element endpoint returns the pad url *and* an Etherpad session
cookie, and the pad exports itself as text to whoever holds it. No API
key needed. Pads are now shown by get_board and indexed for search.
The store's file digest covered id and size on the grounds that file
records are immutable. `PATCH /file/rename/{id}` renames one in place,
so a rename was reported as nothing at all.
Finally, get_board reported an unpublished board as "no permission",
which sends the reader hunting for an access problem that is not there.
smoke gains checks for topic tasks and for pads, and no longer assumes a
populated index or a search term that happens to match. 39/39 live-only
and 41/41 index-backed, against both the live instance and a local one.

You were right that the output was wrong, though not quite for the
reason given: the schema has no textual grade. It is
grade: { type: Number, min: 0, max: 100 } with gradeComment: String, so
"OK" is the comment, not the grade.
What the model does allow is exactly your case — teachers grade with the
comment alone and leave grade unset. Rendering that as "graded (no
numeric grade recorded)" reads as missing or broken data when in fact
the written verdict is the whole grade. It now says "graded by feedback,
with no percentage given", and reserves the it-is-absent wording for
when there is genuinely neither a percentage nor a comment.
Also fixes a real misrepresentation next to it: grade is a percentage,
and both the detail and list views printed it bare, so an 85 could be
read as a mark out of 100, 15 or 6. Now rendered as 85%.
formatGradeState is pure and covered by seven cases, including 0% staying
distinct from "no grade" — the bug that an `if (grade)` test would have
introduced.
85 tests, 38/38 smoke.

You were right that this data never reaches the browser as an API call.
The legacy front end calls the Feathers API server-side for
submission.comment, submission.grade and submission.gradeComment and
renders them into GET /homework/{taskId}. That Feathers API is not
exposed publicly — /api/v1/* 404s — so the rendered page is the only way
to reach these fields from outside.
core/homework-page.ts parses it, hooked on the data-testid attributes
the project's own e2e tests use rather than incidental markup. The page
authenticates by jwt *cookie*; an Authorization header is ignored and
redirects to the identity provider. Every field is optional and parse
failures return undefined, so a markup change degrades to "not found"
and cannot break get_task. The wording distinguishes the two: absent
feedback is reported as not found, never as none given.
Measured on one course: 4 of 7 graded submissions carry feedback no API
call can return — "vollständig und nachvollziehbar", "Feedback siehe
Zettel", and so on.
This exposed a bug in a shared utility: htmlToText decoded only six
entities, so any named entity passed through raw. German content makes
that routine — "vollständig" would have reached the model verbatim
from boards and task descriptions too, not just here. It now decodes
named, decimal and hex references in one pass, so &auml; stays
literal instead of decoding twice, and leaves unknown names alone rather
than mangling them.
Also fixes a documented-recovery bug found while restoring the session:
`docker compose restart` does not re-read env_file, so it silently kept
serving the dead token. `up -d` is correct and the docs said the wrong
thing.
78 tests, 38/38 smoke; verified end to end through Claude Code.

Adds what the API actually permits, which is less than the request asked
for and worth being precise about.
GET /api/v3/submissions/status/task/{taskId} is the only submission
route — no list, no fetch-by-id — so a task id is the only way in. The
probe in the report missed it by trying /api/v3/submissions (404). Its
payload is {id, submitters, isSubmitted, isGraded, grade,
submittingCourseGroupName} and nothing more: no submitted text, no grade
comment, no graded-at. Those lived on /api/v1, which this instance does
not serve at all (404 across the board, confirmed — not the proxy). So
"what feedback did I get" is answerable only when the feedback is a file.
Submitted files are reachable, which covers the main workflow:
get_task now shows the submission id, graded state, grade, group, and
the handed-in files with ids ready for download_file. list_submissions
surveys tasks for "what have I handed in" and "what is still ungraded".
Both state the text/feedback gap rather than implying none was given.
Two things found while building it:
files-storage ignores the parentType path segment when listing —
.../gradings/{id} returns the same records, saying parentType
"submissions". Filtering on each record's own parentType, or a student's
own upload gets reported back as teacher feedback.
get_task could not find this task at all: the task lists only cover the
dashboard, and group-project tasks are absent from both, so it claimed
the id was wrong for a task the account can plainly see. It now falls
back to scanning course pages.
Also bounds live search by measured cost: resolving attachments needs a
request per board element, which is 2s for one course but 325s for all
of them — beyond any client timeout. An unscoped fresh search now reads
text only and says so.
38/38 smoke checks; verified end to end through Claude Code against a
real graded group submission.

GET /api/v3/cards?ids= accepts at most 20 ids. Above that the request
fails with 400 "each value in ids must be a mongodb id" — which blames
the ids when the real problem is how many there are. Express/NestJS
parse the query string with qs, whose default arrayLimit is 20; past it
the repeated params stop being an array and become an object keyed "0",
"1", …, and @IsMongoId({ each: true }) then rejects every value.
I had chunked at 40, having read the controller and its DTO and found no
documented ceiling. The limit is not there — it is in the query parser
underneath them, which I did not think to check. Verified live: 20 ids
return 200, 21 return 400 with identical ids.
The worse half of this was mine alone. The crawler caught assembleBoard
failures and dropped them, so every board over 20 cards vanished from
the index while the crawl reported "failures: none". Board errors now go
into Snapshot.failures and are surfaced by refresh_index.
Impact of both fixes on a full re-crawl: 205 files -> 255, and the
reported board (27 cards, 18 files) reads fully. The two failures that
remain are genuine 403s — boards this account cannot see — and are now
visible rather than silent.
Thanks to the bug report, which had the root cause exactly right.

The CLI talks only to the Pi's /api surface and holds no Schulcloud
credential — only the same bearer token the Claude connector uses. That
is not layering for its own sake: a Schulcloud session dies after two
hours idle and a CLI process lives for seconds, so a CLI with its own
token would be dead most times you reached for it. Routing through the
Pi means one session, one keepalive, one monthly cookie paste.
sync is a one-way mirror, which follows from the data rather than from
scope-cutting: file records are immutable upstream, so there is no
versioning, no conflict resolution and no merge. State is keyed by file
record id with the path as derived output, so an upstream rename moves
the local file instead of duplicating it — verified against the live
server. Verification is size-only because the download endpoint exposes
no ETag and Schulcloud publishes no hash; size still catches the failure
that happens, a truncated download. Downloads land on a .part neighbour
and are renamed, so an interrupted run leaves no half-file that a later
run mistakes for complete. Deletions are reported but not propagated —
a teacher removing a worksheet is no reason to destroy the student's
copy — with --prune to opt in.
what_changed now clamps to the oldest stored generation instead of
refusing, and says it did: "what's new this week" is a reasonable
question to ask a two-day-old index.
Two build bugs caught by the checks rather than by luck: the smoke
harness constructed the app without services, so the index-backed tools
were never exercised; and the Docker build could not see
scripts/copy-assets.mjs, so the image would have shipped without
migrations and silently degraded to live-only.
67 unit tests (9 needing Postgres), smoke green both ways — 34 checks
with an index, 32 without, because graceful degradation is a supported
mode and not a fallback nobody runs.

search now queries the Postgres index and states its freshness in every
result, with fresh=true bypassing it for a live crawl — the agent can
always get current data rather than being quietly misled by a stale
index. Adds refresh_index (per-course by default; a full crawl is ~270
requests), what_changed (generation diff — the API has no changed-since
filter of any kind), and index_status.
/api gives the CLI its backend behind the same bearer token as /mcp:
GET /manifest (cursor + per-file status), GET /files/:id (served from
the mirror with Range support, falling back to a live proxy for files
too large to mirror), GET /status, POST /refresh. Bytes go over plain
HTTP rather than MCP because base64 in JSON-RPC costs a third more and
buffers whole files. An unresolvable manifest cursor returns 409 rather
than silently meaning "everything is new", so a client cannot be tricked
into a full re-download.
Verified end to end against the live instance and a real Postgres:
crawl -> index -> German FTS -> manifest -> ranged download, with 401
on missing token, 400 on a malformed id, and 429 on a too-soon refresh.
Two findings worth recording. The build silently omitted the .sql
migrations from dist, which the store's graceful degradation turned into
"running without the index" rather than a crash — now copied by a build
step. And 3 of 4 sampled course PDFs have no embedded fonts at all: they
are scans, so extraction legitimately yields nothing. That is now
detected and reported as image-only with OCR named as the missing piece,
instead of an indistinguishable "0 characters". It revises the roadmap's
"OCR not needed" note, which held for reading images but not for
indexing them.
49 tests pass.

Moves the reusable half into src/core/ (client, types, board, extract,
text, keepalive) and the MCP half into src/mcp/. The layering was
already clean — nothing in core imported app code or read process.env —
so this is a move, not a redesign, and the smoke suite stayed the oracle
throughout.
The substantive part is core/crawl.ts. The course->board->card->element
->file traversal previously existed only inside tools/search.ts, and the
indexer, what's-new diff and file mirror all need it. It now returns a
typed Snapshot with breadcrumbs, sorted so two crawls of unchanged
content compare equal. Metadata only: downloading and extracting bytes
is an order of magnitude more expensive and only the indexer wants it.
core/match.ts holds the keyword matching, which makes it testable
without a network, and core/text.ts gains the fold/tokenize/snippet
helpers (accent folding is not optional for German).
search now finds strictly more than before — 5 hits vs 3 for
"Datenschutz" — because the snapshot surfaces file-name matches the old
streaming walk skipped. 34 unit tests and 30/30 smoke checks pass.
