Backend (school-service):
- calendar_events.go — Create/List/Delete on cal_school_event with
UUID[] handling for affected_class_ids. Default lead-days [7,1]
if caller omits the array.
- calendar_rollover.go — single-transaction promotion: graduating
classes (grade >= 13) get deleted first so the +1 update doesn't
bump them to invalid grade 14. defaultSchoolYearDates() picks the
next Aug-Jul pair when the caller doesn't specify.
- Handlers + routes: GET/POST /calendar/events,
DELETE /calendar/events/:id, POST /calendar/school-year-rollover.
Frontend (studio-v2):
- EventModal: form with Title / Typ / Datum/Zeit / unterrichtsfrei /
Beschreibung / Sichtbarkeit + Notification-Checkboxen. Per-Type
Farb-Mapping in types.ts.
- DayDetail: Modal das beim Klick auf einen Kalender-Tag aufgeht und
Feiertage + Schulferien + Schul-Events fuer diesen Tag listet,
inkl. Loeschen-Button pro Event.
- RolloverWizard: zwei-Schritt-Dialog mit Datums-Auswahl + Tipp-
Bestaetigung ("SCHULJAHR WECHSELN") gegen versehentliche Auslo-
sung, danach Ergebnis-Card mit promoted/graduated-Counts.
- MonthView gewinnt onDayClick + onAddEvent + onRollover Props,
rendert farb-codierte Punkte fuer School-Events am Tagesrand.
- Page laed Events parallel mit Holidays und reicht alle Handler
nach unten.
Tests:
- Go: 3 neue Tests fuer defaultSchoolYearDates + parseClassIDs.
Validator-Test fuer CreateSchoolEventRequest existiert bereits.
80 Subtests gesamt, alle gruen.
- Playwright: mockCalendarApi gewinnt Routes fuer events GET/POST/
DELETE und school-year-rollover. 6 neue Tests (EventModal open,
submit, DayDetail open, Rollover-Trigger, Confirm-Schutz,
Ergebnis-Anzeige).

Backend (school-service):
- cal_public_event (region, event_type, name_de, name_en, start/end,
UNIQUE(region, event_type, name_de, start_date)) — global snapshot.
- cal_school_config (user_id PRIMARY KEY, bundesland, school year dates).
- cal_school_event — Schul-eigene Termine; CRUD folgt in 9b.
- GET /calendar/holidays?region=&from=&to= — Range-Query against
cal_public_event, ordered by start_date.
- GET / PUT /calendar/config — upsert Bundesland per User.
- SeedFromSnapshot reads internal/seed/calendar_holidays.json on every
boot; idempotent via the unique constraint. Async goroutine so the
HTTP server starts immediately even if the seed file is large.
Data source:
- scripts/calendar-snapshot.sh ruft openholidaysapi.org fuer alle 16
Bundeslaender x 3 Schuljahre und schreibt
school-service/internal/seed/calendar_holidays.json (854 Events,
Stand Schuljahre 2026-2028).
- Dockerfile kopiert das seed/-Verzeichnis ins Image, damit die
Container-Datenbank beim ersten Start gefuellt wird.
Frontend (studio-v2):
- /schulkalender Page mit Gradient + Blobs wie /stundenplan und
/korrektur — gleicher Visual-Style.
- BundeslandWizard: zeigt alle 16 Laender als Dropdown, speichert
bei Klick die Config und switcht zur Monatsansicht.
- MonthView: 6-Wochen-Grid Mo-So, Feiertage rose-toned, Schulferien
amber-toned, heutiges Datum mit Indigo-Ring. Prev/Next/Heute
Navigation.
- lib/schulkalender/api.ts re-uses the stundenplan JWT helper so
auth-mode wechselt nicht.
- Sidebar bekommt einen Schulkalender-Eintrag (Icon mit Datum-Dots,
Pfad /schulkalender) in allen 26 Sprachen.
Tests:
- Go: 3 neue Validator-Tests (Bundesland len=5, EventType oneof,
Pflichtfelder). 77 Tests gesamt, alle gruen.
- Playwright: e2e/schulkalender.spec.ts mit Wizard, Save-Flow,
MonthView-Render, Heute-Button, Sidebar-Link. Hermetisch via
mockCalendarApi.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Auth (Test-Mode):
- middleware.AuthMiddleware now takes a devMode flag. In dev,
requests without Authorization fall back to a deterministic dev
UUID (00000000-...-001) and role=teacher. ENVIRONMENT=production
re-enables the strict 401 path.
- main.go wires devMode = cfg.Environment != "production".
- page.tsx replaces the red 'Anmeldung noch nicht integriert' banner
with a softer Testumgebung notice; the manual-token form moves
behind a nested details block.
Export endpoints (school-service):
- LoadExportLessons joins tt_lesson with tt_period for wall-clock
times; one query feeds both CSV and ICS.
- WriteCSV streams 10 columns including pinned flag.
- WriteICS emits one VEVENT per lesson anchored to a Monday — caller
overridable via ?start=YYYY-MM-DD. RFC 5545 escapes for ',', ';',
'\n' in icsEscape().
- NextMonday helper for the default anchor.
- GET /timetable/solutions/:id/export.{csv,ics} handlers attach
Content-Disposition: attachment so browsers download instead of
rendering.
Frontend:
- lib/stundenplan/api.ts downloadSolutionExport() fetches as blob,
triggers a synthetic <a download> click, and forwards the JWT when
present.
- PlanView gains CSV / ICS / Drucken buttons next to the perspective
selector. The toolbar carries class 'no-print' so window.print()
yields only the grid.
- globals.css @media print rule hides chrome, forces white
background, gives the table proper borders for A4.
Docs:
- docs-src/services/stundenplan/{index,architecture,constraints,
solver-tuning,export}.md with nav entry in mkdocs.yml under
Services → Stundenplaner.
- sbom/stundenplan/README.md lists manually-verified key dependencies
and the policy reference. scripts/stundenplan-sbom.sh generates
full machine-readable inventories via go-licenses + pip-licenses
+ license-checker when those tools are available.
Tests:
- internal/services/timetable_exports_test.go: 4 unit tests covering
CSV column layout + quoting, ICS structure + DTSTART formatting,
icsEscape special chars, NextMonday weekday math.
- studio-v2/e2e/stundenplan-export.spec.ts split out of the main spec
file (LOC budget) — 3 tests for button render, CSV download,
ICS download.
- mockSchoolApi extended with export.csv + export.ics routes.

Backend (school-service):
- tt_solution gains parent_solution_id (self-FK, ON DELETE SET NULL)
and seconds_limit columns via ALTER TABLE IF NOT EXISTS.
- CreateTimetableSolutionRequest accepts optional parent_solution_id
and seconds_limit (5-600s) with binding validation.
- CreateSolution checks parent ownership before INSERT so users can't
fork another tenant's plan.
- New PUT /timetable/lessons/:id/pin endpoint; ownership enforced via
the lesson's solution.created_by_user_id JOIN.
Solver:
- Lesson.pinned now carries @PlanningPin so Timefold leaves locked
cells untouched during the search.
- build_problem() takes optional parent_solution_id; if set, copies
pinned (class_id, subject_id, day, period, room) tuples onto fresh
Lesson objects via greedy first-fit matching. Surplus pinned rows
from curriculum changes are silently dropped.
- _build_factory(seconds) replaces the module-level factory so each
job honours its tt_solution.seconds_limit override.
- persist_solution writes lesson.pinned back so subsequent re-solves
inherit it.
Frontend (studio-v2):
- SolutionList grows three knobs in the create-form: Basieren auf
(parent dropdown, only completed solutions, disabled when none),
Sekunden-Limit (5-600), and the existing Name.
- PlanView cells get a pin/unpin button with optimistic update and
rollback on error. Pinned cells gain an amber ring.
- types.ts + api.ts mirror the new fields; lessonsApi.pin(id, bool).
- HelpPanel: collapsible 6-step Bedienungsanleitung explaining the
setup-to-plan workflow. Anchored at the top of /stundenplan above
the dev token banner.
- page.tsx switches to the same gradient + animated-blob background
used on /korrektur so /stundenplan stops looking like a slate-900
test page.
- JWT dev banner gets a step-by-step explanation of how to grab the
token from DevTools and a non-blocking success indicator (no more
alert()).
Tests:
- school-service: 6 new validator cases for parent_solution_id +
seconds_limit boundaries. 73 subtests total, all green.
- studio-v2: mockSchoolApi adds PUT /lessons/:id/pin route. 5 new
Playwright tests across two suites (parent-selector visibility +
options, seconds-limit input, pin button render, pin-icon flip).
Existing tests adjusted to the new help panel + JWT banner wording.

Frontend additions in studio-v2:
- types.ts adds TimetableSolution, TimetableLesson, SolutionStatus,
CreateTimetableSolution mirroring the Go models.
- lib/stundenplan/api.ts adds solutionsApi with list/get/create/remove/
lessons. Solve trigger is POST /timetable/solutions — school-service
forwards to the solver-service over the Docker network.
- _components/plan/SolutionList: table of past solves with status
badges, hard/soft score, Anzeigen + Loeschen buttons, and a
'Neuen Plan generieren' trigger. Auto-polls every 4 s while any
solution is pending/running, clears the interval otherwise.
- _components/plan/PlanView: Mo–Fr × period weekly grid. Three
perspectives (Klasse / Lehrer / Raum) toggleable via test-id'd
buttons; selector below lists every unique resource with at least
one lesson. Cells colour-coded by tt_subject.color.
- _components/plan/PlanHub orchestrates list + view; default tab in
page.tsx switches from 'klassen' to 'plan'.
Tests:
- mockSchoolApi helper extracted to e2e/_helpers.ts so the spec file
stays under 500 LOC. Helper now also mocks /solutions GET/POST/DELETE
and /solutions/:id/lessons; solutions kept in a closure so POST
appears in the next GET.
- 8 new tests across two suites: SolutionList empty state, list
render, completed-vs-failed Anzeigen visibility, solve trigger;
PlanView placeholder when no selection, grid render, perspective
switching.
- Existing Klassen CRUD tests now click the Klassen tab first
(Plan is the new default landing tab).

Timefold's penalize() emits one score axis per constraint, so the
'penalize as hard OR soft based on is_hard' pattern needs two
constraints. Each rule type now has _hard (filters is_hard=True,
penalises HardSoftScore.ONE_HARD) and _soft (filters is_hard=False,
penalises ONE_SOFT × max(weight, 1)).

Timefold's SolverConfig expects a typed config object, not a dict —

The Python distribution is published on PyPI as 'timefold' — only the
Java module is called 'timefold-solver'. With the correct package the
ARM64 wheel resolves cleanly, so revert the linux/amd64 workaround.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
timefold-solver only publishes x86_64 wheels — pip resolves to no
candidate on linux/arm64. Switch the compose entry to linux/amd64
so the image builds via QEMU/Rosetta on the Mac Mini. The cloud
target for this service is x86_64 anyway.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
ARM64 has no eclipse-temurin:17-jdk-alpine manifest. Switch to the
Debian-based python:3.11-slim and install OpenJDK via apt so the
image builds on both Mac Mini (ARM) and x86_64 hosts.

school-service additions:
- tt_solution + tt_lesson migration. tt_lesson carries three UNIQUEs
(solution+class, solution+teacher, solution+room per slot) so the
DB itself rejects any double-booking the solver might emit by
mistake.
- Solution CRUD + GET solutions/:id/lessons endpoint with joined
class/subject/teacher/room names for display.
- POST /timetable/solutions creates the row then fires off the
solver-service via HTTP (5s timeout, mark failed if unreachable).
- SOLVER_SERVICE_URL config wired through main.go/handlers.
New service timetable-solver-service:
- Python 3.11 + FastAPI + Timefold Solver 1.21 (Apache-2.0). Dockerfile
bundles OpenJDK 17 since Timefold for Python is a JPype bridge.
- app/domain.py — Timefold @planning_entity Lesson with timeslot+room
as PlanningVariables; @planning_solution Timetable holds problem
facts (rooms/teachers/etc.) AND rule-fact collections.
- app/rules.py — frozen dataclasses mirroring 6 of the 15 tt_
constraint_* tables initially.
- app/constraints.py — ConstraintProvider with 3 universal hard
constraints (no double-booking) + 5 DB-driven constraints
(teacher_unavailable_day/window, teacher_excluded_room,
room_unavailable, room_requires_type) + 1 quality soft constraint
(subject_preferred_period). Remaining 9 constraint types ready to
plug in via the same join pattern.
- app/repository.py — async loaders for stammdaten + rules; builds
one Lesson per (curriculum row × weekly_hours), skipping rows
without a tt_assignment teacher.
- app/runner.py — runs solver in ThreadPoolExecutor so the FastAPI
event loop stays responsive. Updates tt_solution status
pending→running→completed|infeasible|failed.
- app/main.py — POST /api/v1/solve (202 Accepted, background task),
GET /api/v1/jobs/{id}, /health. School-service polls tt_solution
directly instead of GET /jobs for the typical case.
- docker-compose.yml adds the service on port 8095, depending on
core-health-check.
Tests:
- school-service: validator test for CreateTimetableSolutionRequest
(allows empty name).
- solver-service: tests/test_domain.py + tests/test_rules.py cover
construction + hashability of the planning facts. Full solve flow
deferred to Phase 8 integration with seed data.

The German „X" markers in the description prop combined a curly „
(U+201E) with a straight " (U+0022). The straight quote prematurely
terminated the JavaScript string inside the JSX expression. Removing
both markers around the example text keeps the description readable
and unambiguously valid JSX.
Test selector for the UnavailableWindow description updated to match
the new wording.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
German curly quotes („…") combined with a closing straight " inside
JSX attribute values were terminating the attribute prematurely, e.g.
`description="Beispiel: „X" (jugendgerecht)."` lost everything after
the inner straight quote. Switch all such descriptions to the JSX
expression form `description={"…"}` so the inner quotes are part of
a JavaScript string literal and parsed correctly.

Backend was already complete in Phase 2; this finishes the UI.
- regeln/_shell.tsx introduces useConstraintCrud (handles list/create/
delete state + reload), ConstraintShell (header, prereq banner,
form toggle, error display, empty/loading/table render), and
useShellStyles for the recurring theme tokens. Each editor now
only carries its schema-specific bits.
- Existing 4 editors (TeacherUnavailableDay/Window, SubjectMax
Consecutive/PreferredPeriod) refactored onto the shell — every
Playwright selector preserved.
- 11 new editors covering the remaining constraint tables:
TeacherMaxHours{Day,Week}, TeacherExcluded{Subject,Room},
Subject{MinDayGap,ContiguousWhenRepeated,DoubleLesson},
Class{MaxHoursDay,NoGaps},
Room{RequiresType,Unavailable}.
- RegelnHub now references all 15 editors directly — no more 'soon'
placeholders. The two duplicate 'Max. Stunden / Tag' entries
(teacher + class) are intentional and disambiguated by group.
Tests:
- e2e/stundenplan.spec.ts: mock routes added for all 11 new constraint
endpoints. RegelnHub suite gains a single test that switches
through 13 uniquely-labelled editors, plus a dedicated test for
the two duplicate 'Max. Stunden / Tag' labels.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Frontend additions in studio-v2:
- PeriodsManager renders the weekly grid as a Mo–So table with one
row per period_index. New entries auto-increment period_index so
the user can hit Anlegen repeatedly for a full day's slots.
- CurriculumManager joins classes + subjects; new entries refuse to
open when either prerequisite list is empty (banner instead).
- AssignmentsManager joins teacher × class × subject with the same
prerequisite-banner pattern.
- regeln/RegelnHub: vertical sidebar grouping all 15 constraint
types by parent entity (Lehrer/Fach/Klasse/Raum). Implemented
editors are clickable, the other 11 are visibly disabled with
a 'soon' tag.
- Three new editors:
TeacherUnavailableWindowEditor (time-window pattern),
SubjectMaxConsecutiveEditor (number-input pattern),
SubjectPreferredPeriodEditor (number range pattern).
- page.tsx wires every tab to its manager; the not-implemented
placeholder is gone (no more empty tabs).
Test coverage:
- e2e/stundenplan.spec.ts rewritten: 23 tests across 7 suites,
covering all 8 tabs, the new managers' prerequisite banners,
sub-tab switching in the RegelnHub, and the disabled state of
not-yet-implemented constraint rules. Each test mocks the
backend via page.route() so the suite stays hermetic.

- 'Lehrer' label collided with a Sidebar entry; scope to <main nav>.
- 'Schmidt, Anna' lived in a closed <option>; assert on count via
select.locator() instead of toBeVisible().
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Frontend additions in studio-v2:
- LehrerManager / FaecherManager / RaeumeManager — same CRUD pattern as
Klassen, with entity-specific form fields and table columns.
- regeln/TeacherUnavailableDayEditor — first constraint editor, joins
against teachersApi to render a readable name in the dropdown and
list. Falls back to a guidance banner when no teachers exist yet.
- page.tsx wires up the new tabs; data-testid attributes added across
managers so the Playwright suite can target them deterministically.
Tests:
- school-service: timetable_constraints_more_test.go fills the
remaining 9 constraint DTOs (TeacherMaxHoursDay/Week,
TeacherExcludedSubject/Room, SubjectMinDayGap,
SubjectContiguousWhenRepeated, SubjectDoubleLesson, ClassNoGaps,
RoomRequiresType). 66 subtests total, all green.
- studio-v2: e2e/stundenplan.spec.ts covers the page shell, tab
navigation, Klassen CRUD with mocked backend, constraint editor's
empty-teacher fallback, sidebar entry. All school-service calls
intercepted via page.route() so the suite is hermetic.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Phase 3 — initial UI for the timetable scheduler:
- app/stundenplan/page.tsx with tab navigation (Klassen / Lehrer /
Faecher / Raeume / Zeitraster / Stundentafel / Lehrauftraege /
Regeln) and a dev-mode JWT entry to authenticate against
school-service until full auth is wired up.
- app/stundenplan/_components/KlassenManager.tsx as the working
prototype for one entity (list / create / delete). Pattern can be
copied for the other 6 stammdaten + 15 constraint editors.
- lib/stundenplan/api.ts exposing typed clients for all 22 endpoints
(7 stammdaten + 15 constraint tables). Constraints use a factory
to keep the file tight.
- app/api/school/[...path]/route.ts proxies the browser through
Next.js to school-service so HTTPS studio-v2 can reach the plain
HTTP backend.
- Sidebar.tsx gains a Stundenplan entry with 26-language labels.
- docker-compose.yml exposes SCHOOL_SERVICE_URL to studio-v2 and
declares the school-service dependency.

When searching for DE/FR/ES/etc. words, the Kaikki entries have empty

- Tab labels (Muttersprache/Schulsprache) now translate with selected language
e.g. Turkish: "Ana dilim" / "Okul dili"
- Info box below tabs explains each setting in the user's native language
e.g. "Evde konustunuz dil. Tum menuler bu dilde gorunecektir."
- Wider dropdown (w-72) to fit translated text
- All 26 European languages covered

- LanguageContext: new schoolLanguage + setSchoolLanguage
- LanguageDropdown: two tabs (Muttersprache / Schulsprache) with flag selection
- UnitBuilder: defaults target language to schoolLanguage
- Stored in bp_school_language localStorage (default: de)
- Shows school flag badge next to main language when different

- Merge two separate language systems (bp_language + bp_native_language) into one
- NativeLanguageContext now reads from LanguageContext (same localStorage key)
- Extend i18n.ts to 26 languages with flags (UI falls back to EN/DE)
- Replace LanguageSwitcher with LanguageDropdown (flags) in learn + parent layouts
- Migration: old bp_native_language value auto-migrates to bp_language
- Onboarding page writes to bp_language (unified key)

- New UnitBuilder component with language pair selector (DE⇄EN, ES, FR, etc.)
- Manual word entry form with auto-suggest from Kaikki dictionary (6M words)
- "No results" prompt to add multi-word terms (e.g. "schottisches Hochland")
- New backend endpoint GET /vocabulary/lookup-translation (any→any via EN hub)
- Updated POST /vocabulary/units: accepts custom_words + source_lang/target_lang
- Split unit endpoints into vocabulary/unit_api.py (500 LOC budget)

When user selects DE and types "Auge", the topic "Eye/Auge" is found

31 curated topics with 683 words (Fruit, Animals, Body, Eye, Sports,
School, Family, Weather, etc.). When user types a word that belongs
to a topic, the topic appears as a suggestion with "Alle laden" button.
Clicking "Alle laden" fetches all words from that topic via Kaikki
and displays them for easy selection into a learning unit.
New endpoint: GET /api/vocabulary/topics?q=banana
