Exercises: WIP Enable Variants Generation with AI - #13533
Conversation
develop currently fails to compile: spring-ai dropped spring-ai-starter-model-azure-openai upstream, so AzureOpenAiChatOptions no longer resolves in ContentExtractionService. Switch to OpenAiChatOptions, mirroring CompetencyOrchestrationService.buildChatOptions, to unblock builds on this branch. This is a stopgap — revert once develop has its own fix.
Competencies are tracked per exercise, not per variant group, so drop the group-level competency UI and data this branch had accumulated: the group edit modal's competency checkboxes/weights, the CourseExerciseGroup.competencyLinks field and its mock data, and the instructor competency-management/course-competency-list mocking. Keep the per-exercise mock contributions shown below the problem statement. Also revert unrelated groupId/groupTitle additions to the shared Atlas competency-contribution component and DTOs back to develop's version, and merge the group edit modal's Name and Max points fields onto one row now that the Competencies column next to Dates is gone.
Pin the quiz export dialog footer to the bottom (scrollable question list above it) instead of letting the Back/Export buttons float over the list, and remove the gap below the footer. Fix the manage-exercises Create cards, which did nothing on click: split the route segment so Angular no longer URL-encodes the slash, and make the bare *-exercises redirects pathMatch: full so /new and /import subpaths reach their real routes.

Fix NaN exerciseId requests by preventing navigation when clicking group sidebar cards (which have no numeric exercise ID). Show the group due date as subtitle on sidebar cards. Reword the group detail info banner to drop the em dash and add a max-points explanation. Wire up breadcrumbs for group detail pages via EntityTitleService so the group title appears instead of the raw "group" path segment. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Cancel in the group edit modal no longer creates a group. Group creation is now deferred to the save handler via a pendingNewGroup signal instead of being triggered immediately on the create button click. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
… live Move the quiz status and mode badges from the title column to the categories column in the experimental manage-exercises table, and remove a deleted exercise from the view without a page refresh. The delete confirmation dialog now shows the course title and test/real course type. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…ling Cap the actions column at the widest button set it needs (60rem) instead of letting it absorb all leftover width as whitespace; the leftover now flows to the title column. Keep wide tables scrolling inside their own card (min-width:0 on the PrimeNG panel grid item) rather than scrolling the whole page on small screens. Convert SCSS comments to block syntax to satisfy no-invalid-double-slash-comments. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…overflow clipping Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add a delete action for exercise variant groups (instructor-only, member exercises are ungrouped rather than deleted) backed by a members-free repository lookup so the ON DELETE SET NULL FK can ungroup cleanly. Move all variant-group translations into a dedicated exerciseVariantGroup.json namespace and wire the footer edit/delete buttons to those keys. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Reuse develop's QuizExerciseLifecycleButtonsComponent (rendered hidden) as the logic engine, while presenting the quiz lifecycle actions as compact buttons consistent with the rest of the experimental action row. Quiz buttons always stay visible and never collapse into the ellipsis; only the main actions overflow. Batched quizzes get a single Batches popover listing each batch's id, password and status (Running/Done) plus Start and Add Batch. Load the data the /with-exercises endpoint omits: propagate course-level access rights to the exercises, compute the client-side quiz status, and fetch quiz batches from the dedicated findForCourse endpoint so they survive a refresh. Merged quizzes get fresh object references so the rows react immediately. Track table rows by id so updating an exercise no longer tears down an open popover. Use faBoxesStacked for batches to avoid clashing with the groups icon. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

The action column collapses buttons into an ellipsis based on widths measured in the DOM. Previously every row kept a hidden measure bar and re-read every button's offsetWidth on each resize tick. Measure each button once for the whole table via a shared cache keyed by the button's visual signature (icon|label|style); the measure DOM is now gated behind needsMeasure() and rendered only while a row introduces an unmeasured button. On resize, only the available width is updated (read live from clientWidth), and change detection is flushed synchronously in the observer callback so the collapse is painted on the same frame.

Reject inconsistent date orderings on exercise variant groups both client- and server-side (ExerciseVariantGroup.validateDates(), disabled Save in the group edit modal), and only let a brand-new empty group adopt a joining exercise's dates for fields it doesn't define yet. Also expose exampleSolutionPublicationDate and the programming-only buildAndTestStudentSubmissionsAfterDueDate throughout the group DTOs, service, and edit modal, which were previously uneditable.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Rework the experimental exercise-row action bar so buttons collapse into the ellipsis menu dynamically without rebuilding the DOM. All main buttons render once in a single stable list; overflowing ones only get a `d-none` class toggled and are mirrored into the menu, so resizing never recreates button elements. Per-button widths are measured once (keyed by translated label) and the available width is the column width minus the always-visible quiz buttons; the fit reserves an exact ellipsis width plus a safety margin so a button is never shown partially clipped. Restore i18n: button labels use translation keys via the artemisTranslate pipe instead of hardcoded strings, and re-measure on language change (German labels are wider). Adds artemisApp.quizExercise.batches and .endQuiz keys. Make the actions column responsive: width:100% + max-width so it grows with available space up to a full button set instead of a fixed width. Remove the now-unused shared width-cache service. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Open the group-edit dialog imperatively through PrimeNG's DialogService from both the exercise edit view (locked timeline date pickers) and the management "edit group" action, sharing one reusable ExerciseGroupEditModalComponent. This replaces the declarative <p-dialog>, whose overlay mis-layered on the first open from inside the large exercise-update form. Fix the first-open render: the variant group's dates are typed dayjs but arrive as ISO strings (the nested reference is not date-deserialized), so the timeline's date.toDate() threw and aborted the dialog render. Coerce to dayjs on the way into the modal. Restore the dialog title styling (.p-dialog-title) on custom header templates, and skip the persist call when the group is saved unchanged.

@DominikRemo Changes requested: the current head can alter quiz grading metadata, silently violate NEW_GROUP placement, leave rejected jobs stale, and regress shared date-picker layout. The captured client-test and Codacy failures are directly attributable to changed lines; the generic server-test/server-style evidence and unpinned E2E report are not attributable, while a non-required E2E job remains in progress. The other unresolved review threads are also still supported by the current source.

@DominikRemo [high] This host-level style binding directly triggers the captured client-test failure (uses semantic dialog sizes instead of host styling). Replace it with the dialog's semantic size="large" input so the integration contract passes.

In src/main/webapp/app/course/manage/exercises/create-variant-modal/exercise-variant-ai-modal-wizard.component.html, the host style binding violates the semantic dialog-size contract and fails the client test. Replace it with size="large".

@DominikRemo [medium] The model-controlled JSON is checked for question type and validity, but its points and scoringType are accepted unchanged. A valid response can therefore change grading and QuizExerciseService.save recalculates the quiz maximum from those altered points, despite both the prompt and plan declaring these fields invariant. Copy both grading fields from existing onto updated before saving and cover this with a regression test.

In src/main/java/de/tum/cit/aet/artemis/hyperion/service/variants/QuizVariantTools.java, replacement JSON can change question points and scoring type while still passing validation. Restore both fields from the existing question before persisting and add a test that attempts to alter them.

@DominikRemo [medium] The bounded executor rejects the 41st queued/running job with TaskRejectedException, and that exception occurs at this proxy call before runJobAsync executes. Because the job was already stored, the request returns 500 while an ANALYZING record remains until stale reconciliation runs ten minutes later. Catch submission rejection here, transition the new job immediately to a failure state, and return an explicit 503 response.

In src/main/java/de/tum/cit/aet/artemis/hyperion/web/HyperionExerciseVariantResource.java, executor rejection occurs after the job is persisted and leaves it nonterminal. Catch TaskRejectedException, fail the stored job immediately, and return HTTP 503.

@DominikRemo [medium] NEW_GROUP is accepted even when the source is already grouped or is a non-individual quiz. The finalizer then creates the new group, silently skips the source, adds only the variant, and reports COMPLETED, contradicting the UI's “with original” contract; this is also reachable when source state changes during generation. Reject ineligible requests here and recheck eligibility before creating the group so a concurrent change becomes a finalization warning instead of a false success.
🤖 Prompt for AI agents
In src/main/java/de/tum/cit/aet/artemis/hyperion/web/HyperionExerciseVariantResource.java, NEW_GROUP accepts sources that cannot join the promised group and later completes with only the variant. Validate source eligibility here and make finalization fail before group creation if eligibility changed.

@DominikRemo [medium] This edit removes the :host { flex: 1 1 auto; min-width: 0; } rule even though the replacement comment still describes that behavior. Date pickers used as flex children, such as the build-queue date filters, consequently stop growing to the available row width and can force sibling content out of alignment. Restore the host flex sizing rule.

In src/main/webapp/app/shared-ui/date-time-picker/date-time-picker.component.scss, the host flex sizing was removed and shared date pickers no longer fill flex layouts. Restore :host { flex: 1 1 auto; min-width: 0; }.

@DominikRemo [high] Codacy's other action-required annotation is on this newly emitted, unbounded array schema.

The develop merges resolved a number of files in favour of this branch's older copies, re-introducing comment churn and undoing fixes that had landed on develop separately. Restore those files to develop's version: - the date-time-picker SCSS, whose branch copy dropped .icon-full-size, .visible-date-warning, .date-time-picker-warning-border and the inputgroup radius fix while the template still uses all four - the group-edit modal's headerStringKey() computed and its unit test, [showButtons] on the max-points input, and the tum-ui-message bindings - the group-detail :focus-within rule and the mobile-overflow grid fix - import order and doc comments across the exercise management, quiz and programming components - Exercise.validateBaseDates' JavaDoc and @nullable placement, and the problem-statement endpoint's user lookup Also restore the titleLowercase name in the Playwright helpers, keeping only its body fix: the rename left CourseTabs.spec.ts importing a symbol that no longer existed. Finally drop code nothing references: ExerciseVariantJobService's recordProgress, VariantJob's setStepOutputs, the .result-success wizard styles, and the tum-ui table directive stylesheet (a directive cannot carry styleUrls, so it was never loaded).

Adding findUnresolvedTaskTestReferences rewrote this class wholesale and dropped verifyTaskReplacementInProblemStatementTest and verifyRegexCharacterEscapeForTaskReplacementTest, which were the only coverage of replaceTestNamesWithIds, including its escaping of names like Outerclass$Innerclass#method. Add both back next to the new tests. They build a real ProgrammingExercise rather than reusing the shared fixture, which is a Mockito mock and would swallow the setProblemStatement call the assertions read back. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Regenerating the spec for the three new variant endpoints also rewrote the tutorialgroup paths, because the checked-in spec is stale relative to the server's dual request mappings. That churn is unrelated to this feature and made up most of the file's diff. Keep only the variant paths and their schemas. The generated Angular client is unaffected: none of the tutorialgroup drift had reached it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Extracting the collapsible action row into a shared ExerciseActionBarComponent is already under review in its own pull request, which touches the same files. Drop it here so this branch carries only what variant generation needs. exercise-actions and exam-exercise-row-buttons go back to their develop implementations. The course row gains a create-variant-ai entry in the action list it already builds, and the exam row gains a button in its markup, both opening the wizard. The exam row binds the course id and exam flag explicitly because its exercises carry neither a course nor an exercise group. Also drop the Tailwind @source entries for the removed component and for the directories that no longer use utility classes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Provisioning read the variant's test cases off the exercise the import service returns. That exercise comes back detached from findForCreationById, whose graph no longer covers testCases since the query optimizations landed on develop, so touching the lazy collection threw and every programming generation failed in PROVISIONING with a LazyInitializationException. Read the test cases from the repository instead, as this class already does elsewhere. The generation integration tests failed for a related reason: course roles moved to an explicit join table, so a course now has to enrol its users instead of matching them by group name. Every request was answered with 403. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

@DominikRemo The current head still contains the blocking defects documented in the unresolved threads: quiz grading metadata remains model-controlled, executor rejection leaves a stored job behind, and NEW_GROUP can complete without grouping the source. The dialog also retains its host style and click-only selection cards, while Codacy’s action-required annotation still points to the changed format parameter. The red server-style evidence is not specific enough to attribute separately, and the E2E report is unpinned to this head.
…e-send poll fails DO NOT MERGE THIS COMMIT. Diagnostics only, to be dropped once the cause is known. The poll can only report "count was 0", which does not distinguish the four things that produce it: no re-send issued at all, one issued but still answered 503 because the route outage had not been lifted, one rejected by the server, or one that succeeded and was dropped by the reloadCommitted gate. Records every request and response on the endpoint, requests included so "never sent" is distinguishable from "sent, never answered", and prints them when the poll fails. The assertion and its failure are unchanged; the original error is rethrown. The test currently fails on nearly every run (also on #13533, #13532, #13526 and #13517), so one CI run should identify the cause.
Conflicts resolved: - exercise-actions / exam-exercise-row-buttons (.ts + .html): develop (#13496) extracted the collapsing action row into the shared ExerciseActionBarComponent. Took that refactor and re-expressed the "Create Variant with AI" action as a data-driven ActionItem (kind: 'button', id: 'create-variant-ai') so it collapses into the overflow menu like every other action. The wizard element stays outside the bar so it never becomes one of its items. - openapi.yaml: both sides added endpoints at the same position; kept both the variant-jobs endpoints and develop's assessment-criteria generation endpoint. Semantic conflict (no markers, would have failed the build): - ExerciseVariantJobService was Hazelcast-based, which develop's new DistributedDataProviderArchitectureTest (#13352) forbids in production code. Migrated it onto DistributedDataProvider, mirroring HyperionCodeGenerationJobService: IMap -> DistributedMap and the map-level MapConfig TTL -> getExpiringMap(name, Duration). The per-key lock/unlock that the heartbeat/cancel lost-update fix depends on carries over unchanged. - The two variant job tests followed. The concurrency regression test now drives LocalDataProviderService instead of an embedded Hazelcast member: LocalMap backs lock() with a real per-key ReentrantLock, and the race is between two threads in one JVM, so it reproduces without paying for a cluster member.

Included review availability: Your plan provides up to 4 included reviews per hour; 3 remain after this review.
The variant-generation code violated seven ArchUnit rules, failing the Server Code Style job. All violations are mechanical; no behaviour changes. - Annotate VariantJobStartDTO and VariantJobDetailDTO.StepOutputDTO with @JsonInclude(NON_EMPTY), as every DTO in the module must be. - Replace jakarta.annotation.Nullable with org.jspecify.annotations.Nullable in seven places. These were the last jakarta uses in src/main/java. - Mark HyperionVariantAsyncConfiguration @lazy like every other Spring component. - Rename the five @service classes so their names end in Service: ExerciseVariantGenerationPipeline, ProgrammingVariantAdapters, QuizVariantAdapters, VariantAgentLoopRunner and VariantTypeRegistry. Their test classes and the javadoc naming them follow. - Declare the test repositories rather than the production ones in ExerciseVariantGenerationIntegrationTest, VariantBuildVerificationServiceJointWaitTest and ProgrammingExerciseTaskServiceTest. Raise the module's dtoNameEndingThreshold from 6 to 9: the branch adds VariantGenerationEventDTO.Type, VariantPlacementDTO.PlacementType and VariantNarrativeStyle, all of the same two kinds the threshold already documents.

Five defects found in review, none of which any gate caught. Quiz grading was model-controlled. replaceQuestion restored only the id and the statistic from the source question, so a replacement that also rewrote points or scoringType deserialized cleanly, passed isValid(), and reached QuizExerciseService.save, which recomputes the quiz maximum from the altered points. Both fields are now restored from the source question. A provisioned variant could be orphaned. run() caught only JobCancelled and PhaseFailed, but the jobService bookkeeping calls around the phases are not wrapped by runPhase, so a job-store failure escaped to the task service. That handler deletes nothing, yet fail() cleared variantExerciseId unconditionally — erasing the only pointer to an exercise that still existed, along with its repositories and build plans. The pipeline now has a terminal catch that runs the usual cleanup, and the safety net uses a fail variant that keeps the id. Executor rejection returned 500 and left a phantom job. The variant pool is bounded, so submission can be refused after the job record is already stored. Rejection is now caught, the stored job is failed immediately, and the request answers 503 instead of leaving an ANALYZING entry in the tray until staleness reconciliation runs. NEW_GROUP could report a false success. Finalization already re-checked whether the source may join the group, but only logged a warning and carried on, so a job whose source was silently skipped still completed. Placement now returns warnings, which the pipeline folds into the job and which downgrade the outcome to DRAFT_WITH_WARNINGS. The task-marker separator cleanup rewrote whole problem statements. Dropping an unresolvable testid left a dangling comma, and the tidy-up ran over the entire statement, so a code sample containing "foo(a, )" or "[1,,3]" was silently corrupted. The cleanup is now scoped to the task markers, and a statement from which nothing was dropped is returned untouched. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The cancellation test selected its job with "the first non-terminal job of this user". Other tests in the class start jobs for the same login that never reach a terminal phase, TEST_PREFIX is a constant, the job map is shared and never cleared, and JUnit does not guarantee method order — so the test could cancel a leftover job and then wait 60 s for a cancellation that never came. It now selects by its own job id, waiting for that id because the pipeline runs asynchronously. waitUntilRemoteHasCommit had no callers. Reviewers flagged that it cannot signal a timeout and swallows every Git error silently; since nothing calls it, remove it rather than fix it. That also leaves GitService injected but unused, so drop it from the constructor. mock_llm's log_message shadowed the `format` builtin, which Codacy reports as action-required. BaseHTTPRequestHandler passes the argument positionally, so the parameter can simply be renamed and the suppression removed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The four adaptation cards in step 1 were divs with a click handler and no tabindex, role or key handling. They are the only way to choose what the variant changes, so a keyboard user could not select anything and the step's Next button stayed disabled — the wizard was unusable without a mouse. Make them real toggle buttons carrying aria-pressed. A button may only contain phrasing content, so the heading, hint and icon wrapper become spans with their own BEM classes, and the SCSS undoes the UA button styling the card design does not want. Keyboard focus now also draws a visible ring. Convert the three href-less disclosure anchors (phase step output, draft warnings, result summary) to buttons with aria-expanded for the same reason. The tray entry keeps role="button" — it hosts the cancel button, so it cannot become a real button — and gains the Space handler that contract requires, suppressing the default so the key does not scroll the page behind the popover.

A failed websocket publish could destroy a finished variant. Every terminal transition writes the new phase first and publishes afterwards, so when the publish threw, the exception escaped complete() into the pipeline's terminal catch — which deleted the generated exercise and overwrote COMPLETED with FAILED. That catch was introduced in the previous commit; before it existed, the task service's already-terminal check kept the job intact. Fix both ends: publish now swallows and logs a delivery failure, because notifying the client is best effort and must never propagate into state-changing code, and the terminal catch keeps the variant when the job has already reached a terminal phase. Cover both with a test class that stubs the websocket service to throw. Give the wizard's free-form controls accessible names. The domain input, the custom-instructions textarea and the six new-group settings had a styled <p> or <div> beside them instead of a label, so a screen reader announced no name. Each control now has an id and a matching <label for>; the label rules get display:block since labels are inline. The two radio-group headings stay as they are — a <label for> cannot address a group, and each radio already carries its own label. Name the AI variant action. The tooltip key read "Variante erstellen" / "Create Variant", so neither locale mentioned AI; both now say so. The button is icon-only and a tooltip is not an accessible name, so it also gets an aria-label from the same key. Abort the E2E runner when the mock LLM never becomes ready, instead of warning and then pointing Spring AI at a dead port. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Summary
Instructors can now let AI create a variant of an existing exercise. You pick what should change (difficulty, application domain, narrative style, or your own instructions), say where the variant should go, and Hyperion generates a real, build verified Artemis exercise in the background. Generation runs as a phased pipeline that plans the change, provisions a copy, applies the change through tools, and verifies the result against objective gates: solution build green, template build red, task to test links intact, quiz validity, semantic consistency. It repairs what it can within a bounded attempt and token budget. Programming exercises and quizzes without drag and drop questions are supported, both in courses and in exams.

Motivation and Context
Artemis already supports exercise variant groups, so an instructor can hold several equivalent versions of an exercise and hand a different one to each student. Writing those versions is the expensive part. A second version of a programming exercise means re-theming the problem statement, template, solution and tests consistently, keeping the task to test links intact, and checking that the solution still builds green while the template still fails. That is hours of work per variant, which is why variant groups tend to stay single member in practice.
This PR generates them instead. Hyperion already owns Artemis' LLM backed exercise creation, so the generator lives there and reuses its prompt templates, context renderers, chat client and token accounting. The output is not a draft for someone to fix up. It is a provisioned Artemis exercise that had to pass the same checks a careful instructor would run before publishing.
Description
The pipeline.
ExerciseVariantGenerationPipelineruns one job through an explicit phase machine: analyze the source, plan the change with one structured LLM call, provision a real copy of the exercise, then loop transform, verify and repair until the gates are green or the budget (5 attempts, 500k tokens) runs out, and finally place the variant. Nothing in the pipeline is type specific.VariantTypeRegistryresolves an exercise type to five capability adapters, so supporting a new type means adding one bean.A job ends as completed, cancelled, failed, or draft with warnings. Failures and cancellations delete the half provisioned exercise through the regular
ExerciseDeletionService, so repositories and build plans are cleaned up properly. Once finalizing starts, the variant is never thrown away again: even a placement failure only downgrades it to a flagged draft. For both failures and flagged drafts, one extra LLM call turns the recorded step outputs into a short note on what happened and how to continue, so instructors do not have to read raw build logs.Verification. The gates run in order of cost: solution build (compiles, all tests pass), template build (runs tests, scores 0 %), task to test references (every test named in a task marker resolves to an active test case), quiz validity and file references, an LLM self critique soft gate for quizzes, and a semantic consistency check between problem statement and artifacts. Findings go back into the next repair round verbatim. If the same finding survives a repair, a signature comparison over the last rounds detects the stuck loop and escalates the prompt. Template and solution builds are submitted together and awaited jointly, so a verify round costs one build wait instead of two.
Agent tools. The programming agent gets batched, repository aware tools: read, search, edit, write and delete across template, solution and tests in a single call, plus test case listing, problem statement replacement and a unified diff against the source exercise. Quizzes get the equivalent for questions. Batching is the point, because it turns dozens of sequential round trips into a handful.
Jobs.
ExerciseVariantJobServicekeeps jobs in a Hazelcast map with a 24 hour TTL and is the only writer of job state as well as the only publisher of the per job WebSocket topic, so what the client sees cannot drift from the stored record. Several variants of the same exercise can generate at once, which is deliberate, so there is no dedup. Jobs run on their own bounded executor instead of the sharedtaskExecutor, whose two core threads would otherwise let two variant jobs starve every other async task in Artemis. If a worker node disappears, its job is reconciled to a stale failure on read rather than spinning until the TTL expires.REST. Four endpoints under
api/hyperion/, all behindHyperionEnabled: start a job (@EnforceAtLeastEditorInExercise), list your jobs, fetch one job's detail, and cancel a job (@EnforceAtLeastEditor, additionally scoped to the initiating user, so foreign, unknown and expired job ids are all 404 and cannot be probed). The exercise type is read server side. The client's visibility rule is mirrored at the REST boundary rather than trusted.openapi.yamland the generated TypeScript client are regenerated.Client. The wizard walks through select, configure, placement, live timeline and result. Exam exercises skip placement because a variant always joins the source's exercise group. The result step distinguishes success, flagged draft and failure, each with its own guidance, the step log behind a toggle, token usage and an AI content disclaimer. Closing the wizard with "Run in Background" hands the job to a navbar tray that shows progress, needs attention state and cooperative cancel, and stays hidden for anyone below editor. Live updates come from per job WebSocket topics into a signal based job list, with REST as the authority on reconnect. New UI is TUM UI and Tailwind with semantic tokens only, checked in both themes.
Changes to existing code. The collapsible action row from the exercise management table became a shared
ExerciseActionBarComponent, now also used by the exam exercise group rows, so both render and collapse identically and only differ in theActionItem[]they build. Quiz list endpoints report a newhasDragAndDropQuestionsflag via one id query instead of loading every question graph, and that flag is what hides the AI action for unsupported quizzes.ProgrammingExerciseTaskServicegainedfindUnresolvedTaskTestReferences, which only matches active test cases. Matching inactive rows used to let a variant with renamed tests pass verification while every task was silently unlinked. Programming exercise updates now pin a group member's timeline back to its owning group before validating. The rest are small follow ups on course scores, sidebar, date time picker and table styling.Testing infrastructure.
