moved this from Done
to In Progress
in Communication Webclient
Add the DTOs, job type, connector method and status-callback endpoint for the new Course Memory ingestion webhook (POST /api/v1/webhooks/course-memory/ingest), mirroring the existing FAQ ingestion plumbing.
Add CourseMemoryIngestionService (public-channel guard, thread building with author roles, settings) behind a CourseMemoryIngestionApi facade, and hook the two event-driven triggers into AnswerMessageService: tutor verification (IRIS_AUTO/IRIS_CORRECTED) and thread resolution (THREAD_RESOLVED).
Add CourseMemoryIngestionIntegrationTest covering the source mapping, thread building, and public-channel/de-dup guards via the mocked Pyris webhook, plus the matching IrisRequestMockProvider helper. Bump the iris DTO-naming threshold for the new PyrisCourseMemorySource enum.
The tutor verification dashboard was re-implemented and merged as #13213, so this branch is now based on develop instead of the stale #12561 branch. Bring the Course Memory ingestion code in line with the APIs develop has since moved to: - Status updates use the run-state API (PyrisRunState / PyrisStatusErrorDTO) instead of the removed PyrisStageDTO, and the execution DTO drops initialStages, which Pyris no longer accepts. - PyrisPipelineExecutionSettingsDTO gained a supportLevel parameter; ingestion passes MODERATE like the other webhooks. - Tutor roles are resolved via AuthorizationCheckService instead of the removed User.groups collection and UserRepository.findUsersWithGroupsByIdIn.

WalkthroughCourse Memory now ingests eligible verified or resolved Iris threads and removes entries for deleted or restricted channels. Pyris jobs and callbacks report operation status. Course conversations display localized websocket alerts. ChangesCourse Memory integration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR adds Course Memory ingestion and retraction, but the current implementation can delete a valid memory when a newer answer is not dashboard-verified, preserve stale text after verified-answer edits, and retain entries when Iris-disabled channels are removed. These concrete data-correctness and cleanup risks should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

269-277: 🚀 Performance & Scalability | 🔵 Trivial | 🏗️ Heavy liftConsider dispatching the webhook off the request thread.
ingestperforms a job registration and a synchronous HTTP POST to Pyris inside the communication request (for exampleAnswerMessageService.verifyAnswerMessage). If Pyris is slow, the tutor's verify or resolve request blocks for the duration of the REST timeout. The lecture and FAQ ingestion paths run their webhooks from asynchronous services. Running this dispatch with@Asyncwould keep the communication response time independent of Pyris latency.🤖 Prompt for AI Agents

resolveTutorRolescallsauthCheckService.isAtLeastTeachingAssistantInCourseonce for each distinct non-bot author.

The TTL selection now tests three concrete job classes. Each new ingestion job type requires an edit here, and a missed edit silently applies the short TTL. A shared marker interface, for example
IngestionJob, would make the condition a singleinstanceof IngestionJobtest.As per coding guidelines "Use Java 25 features such as records, sealed classes, and pattern matching where appropriate."

- Around line 339-349: Move the Course Memory update triggered by
deleteAnswerMessageById into a separate transaction context after the deletion
commits, ensuring fetchThread reloads a detached, current parent Post without
the deleted AnswerPost attached. Preserve the existing contributedToCourseMemory
guard and error logging while updating the courseMemoryIngestionApi invocation.

- Around line 8-13: Update the Javadoc for the TUTOR_WRITTEN enum constant in
PyrisCourseMemorySource to label it as Trigger B, matching the dispatch behavior
in CourseMemoryIngestionService.handleResolutionChange; leave the other trigger
descriptions unchanged.
In
`@src/main/java/de/tum/cit/aet/artemis/iris/service/pyris/PyrisConnectorService.java`:
- Around line 419-430: Update executeCourseMemoryIngestionWebhook and

src/main/java/de/tum/cit/aet/artemis/iris/service/pyris/PyrisConnectorService.java
at lines 419-430 and 439-450 to return a success flag, returning failure when
dispatch catches RestClientException or IllegalArgumentException; merge the
duplicate HttpStatusCodeException and RestClientException handling into one
catch. Update the CourseMemoryIngestionService caller to push FAILED when either
webhook reports unsuccessful dispatch.
In
`@src/test/java/de/tum/cit/aet/artemis/core/connector/IrisRequestMockProvider.java`:
- Around line 191-201: Update the endpoint paths used by
mockCourseMemoryIngestionWebhookRunResponse and
mockCourseMemoryDeletionWebhookRunResponse to include the /api/v1/webhooks
prefix, matching PyrisConnectorService while preserving their existing DTO and
response handling.

Spring Data JPA repository query methods default transactional @transactional on interface method annotations Spring AOP
💡 Result:
In Spring Data JPA, repository methods follow specific transactional behaviors depending on whether they are standard CRUD methods or custom query methods [1][2]. Default Transactional Behavior By default, Spring Data JPA repositories are transactional, governed by the SimpleJpaRepository implementation class [1][3]. - CRUD Methods: Standard methods inherited from CrudRepository (e.g., save, delete, findAll) are annotated with @Transactional [1][3]. Read operations default to @Transactional(readOnly = true), while write/modifying operations use a plain @Transactional [1][4]. - Custom Query Methods: Declared query methods (e.g., repository interface methods using @Query or derived query methods like findByLastname) do not inherit transaction configuration by default [1][2]. They are not transactional unless explicitly configured [1]. Configuring Transactions If you require your custom query methods to participate in a transaction, you must explicitly annotate them or the repository interface [1][4]. - Repository Level: Annotating the entire repository interface with @Transactional(readOnly = true) ensures all methods, including custom query methods, are executed within a read-only transaction by default [1][5]. - Method Level: You can override this behavior or provide specific configuration for individual methods. For example, adding @Modifying and @Transactional to a delete query method ensures it executes with readOnly = false [1][4]. Technical Implementation Spring AOP manages this behavior through proxying [6][7]. The @Transactional annotation serves as metadata that the Spring infrastructure uses to wrap the repository bean in a transactional proxy [6][7]. If you wish to disable this default transactional behavior across all repositories, you can set the enableDefaultTransactions property to false in the @EnableJpaRepositories configuration [8][9]. Note on Performance The readOnly = true flag provides performance optimizations, such as instructing Hibernate to skip dirty checking, which can significantly improve performance for large object trees [4]. However, it does not strictly prevent write operations, as the effectiveness of this hint depends on the underlying database and JPA provider [4][10].

Hibernate query update entity collection associations already in persistence context remove collection behavior
💡 Result:
In Hibernate, when you remove an element from a collection that is part of a persistence context, the behavior depends on the collection mapping and whether the association is bidirectional or unidirectional [1][2]. Hibernate tracks changes to these collections by wrapping them in a PersistentCollection [3]. During the flush process, Hibernate synchronizes the in-memory state of these collections with the database [4]. For many-to-many or one-to-many associations, removing an item from the collection typically results in Hibernate executing a DELETE statement for the association row in the link table (for many-to-many) or updating the foreign key column to null (for one-to-many), depending on the specific mapping configuration [5][6][7]. If you remove all elements from a collection, Hibernate may clear the entire association by deleting all corresponding rows in the database [1][8]. Key considerations for managing this behavior include: 1. Bidirectional Associations: It is mandatory to synchronize both sides of a bidirectional relationship [9]. If you only remove an entity from the collection on the parent side, the database state may not update correctly if the inverse side (the child) still holds a reference to the parent [9]. Always provide helper methods (e.g., add/remove) on your entities to ensure both sides of the association are kept in sync [9]. 2. Performance: Modifying a collection—especially lists or bags—can sometimes be inefficient if Hibernate determines it must "recreate" the collection state by deleting and re-inserting elements, rather than issuing specific delete or update statements [1][8]. Using an @OrderColumn can help improve performance for list-based collections by allowing Hibernate to perform more targeted updates instead of full collection recreation [1][8]. 3. Entity State Transitions: If the collection association includes cascade settings (like CascadeType.REMOVE or CascadeType.ALL), removing an entity from the collection may also trigger the deletion of the child entity itself from the database, rather than just severing the association [1][2]. To ensure consistent behavior, you should always maintain the integrity of the object graph within your Java code, as Hibernate relies on the in-memory state of these collections at flush time to generate the appropriate SQL [4][9].

site:vladmihalcea.com Hibernate first level cache entity query modified associations after flush
💡 Result:
In Hibernate, the first-level cache (the Persistence Context) acts as a transactional write-behind buffer that stores managed entities [1][2]. When you modify an entity—including its associations—within the Persistence Context, those changes are held in memory and are not immediately synchronized with the database [1][3]. When a flush operation occurs, Hibernate performs "dirty checking" to synchronize the in-memory state of managed entities with the underlying database [2]. During this process, Hibernate compares the current state of the managed entities in the first-level cache against the "loaded state" (a snapshot taken when the entity was originally fetched) [1]. If discrepancies are detected, Hibernate enqueues the necessary SQL statements (INSERT, UPDATE, DELETE) to align the database with the current state of the Persistence Context [4][3]. Regarding modified associations specifically: 1. Consistency and Synchronization: Hibernate does not automatically manage the synchronization of both sides of a bidirectional association [5][6]. It is the developer's responsibility to ensure that both sides of an association are updated in memory before the flush occurs [5]. Failure to manually synchronize both ends of a bidirectional relationship can lead to inconsistent state in the Persistence Context, which may result in data integrity issues or incorrect SQL being generated during the flush [5]. 2. Flush Behavior: The flush operation ensures that all pending state transitions—including association changes—are reflected in the database [3]. Because Hibernate uses a write-behind strategy, the actual SQL execution is deferred and optimized [2][3]. It is important to note that the flush order is specific (e.g., entity inserts generally precede collection updates or removals) [4]. 3. Data Visibility: Flushed changes are visible only within the current database transaction [3]. They remain pending in the database until the transaction is committed [3]. To ensure reliable behavior, always use helper methods to synchronize both sides of a bidirectional association immediately after modifying them in your application code [5][6]. Do not rely on Hibernate to reconcile asymmetric bidirectional associations during the flush process [5].

Use a separate transaction context for the re-fetch.
deleteAnswerMessageById performs the deletion and then calls courseMemoryIngestionApi.ifPresent(...) from the same persistence context. The pass-through AnswerMessageService.findById() and findByIdWithPessimisticWriteLock() paths both load the parent Post, so the parent can remain in this transaction with the deleted AnswerPost still attached. fetchThread() then selects it, causing CourseMemoryIngestionService to re-ingest or re-anchor on a deleted answer. Run the Course Memory update in a separate transactional boundary or load the thread as a detached state without caching the parent from this request.

@toukhi The implementation forwards opted-out participants' sibling replies to Pyris, unlike the existing redaction path. It also leaves Course Memory stale after ordinary answer edits and certain mixed student/tutor resolution transitions, while synchronous webhook failures can strand runs after a misleading TRIGGERED status. These current-head high and medium issues require changes.

@toukhi [high] buildThread includes every visible sibling answer and later serializes its content without checking that answer author's NO_AI choice. A tutor resolver or verified Iris reply can therefore forward and persist another participant's opted-out reply in Pyris; PyrisPostDTO explicitly redacts this same case.

@toukhi [medium] The fallback considers student-authored resolving answers, but the caller later returns without ingesting or deleting when that student answer is selected. For example, after a tutor answer was ingested, a newer student answer can remain resolving when the tutor answer is unmarked or deleted; this selects the student answer and leaves the obsolete tutor entry stored even though no memory-worthy answer remains.

@toukhi [medium] Every synchronous dispatch failure is swallowed. The caller has already created a three-hour job and emitted TRIGGERED; because Pyris never received the request, no callback can emit FAILED, so the user sees a start notification followed by silence and the job merely expires.

Do not skip cleanup when Iris is disabled.
If a course disables Iris before a channel is restricted or deleted, this return prevents the deletion webhook. The stored entries remain in Pyris and can become visible again if Iris is re-enabled. Run deletion cleanup regardless of the current course setting.

…tion Ingest student-authored answers. Trigger B skipped any thread whose resolving answer was written by a student, which excluded most resolved threads in a course. The trust tier now follows the endorsement rather than the authorship: a tutor marking any answer as resolving yields TUTOR_WRITTEN, anyone else yields THREAD_RESOLVED, which Pyris already labels as not tutor-verified when it serves the entry. Reach automatically published Iris answers. An answer posted on a high confidence score is stored verified but never passes through the dashboard, so Trigger A never fired for it, and Trigger B skipped every bot-authored answer — such an answer could not enter memory by any path. The two are told apart by verifiedBy, queried as a projection rather than read off the lazily loaded association so the hot thread-loading query keeps its current joins. The anchor fallback stays restricted to dashboard-verified answers: it exists to stop a deletion, not to start an ingestion. Redact participants who opted out of AI. Only the question author and the resolving author were checked; every other participant's reply was forwarded verbatim and fed to the extraction model, unlike the autonomous tutor path, which has always redacted them. Their slot is kept so the thread reads in order, with the flags cleared so a placeholder can never be merged into the stored answer. Resolve the model environment across the thread. Ingestion sent a hardcoded CLOUD_AI, so a thread whose participants asked for on-premise inference still had its transcript extracted by the cloud model. It now takes the most restrictive choice of everyone whose content is forwarded, matching what the autonomous tutor run does. Kept local rather than shared with that service so this branch stays independent of it; fold the two together once both are on develop. Keep entries in step with their source. Editing a resolving answer, or the question of a resolved thread, now re-ingests — previously the entry kept serving the wording that had just been corrected. Deleting a channel or making it private retracts everything mined from it, because eligibility is only evaluated when an entry is written. Also: send the real isPublicChannel instead of a literal true, which made the Pyris fail-closed check a no-op, and pin the pipeline variant to "default" — the course variant was sent, so a course set to "advanced" had every ingestion rejected with a 400 the connector swallows. Thread author roles now resolve in one query instead of one per author.
Addresses review feedback on the Course Memory ingestion PR. A thread whose surviving anchor is a dashboard-verified Iris answer was skipped outright, on the grounds that Trigger A owns those answers. But entries are keyed on the thread root, so the entry may hold what a different answer wrote: a resolving staff answer that has since been un-marked or deleted left its text in place, and an edit to the verified Iris answer itself never reached the entry at all. The skip is now a re-dispatch under Trigger A's provenance, passing the corrected content verbatim as existingAnswer and carrying the answer's own verifier rather than whoever triggered the pass. The verifier login is queried instead of navigated, since verifiedBy is lazy and not part of the eager thread fetch. Both Course Memory webhook methods return whether Pyris accepted the request. TRIGGERED is pushed before the POST and no status callback follows a request that never arrived, so the caller now closes the run out with FAILED instead of leaving the client showing it as in progress. The HttpStatusCodeException catch blocks are dropped: the type is a subclass of RestClientException and both bodies were identical. Toggling channel privacy retracted entries whenever isPublic went false, but eligibility is isPublic OR isCourseWide, so a course-wide channel that the whole course can still read lost valid memory. Retraction now requires both flags to be down. The two negative ingestion tests asserted nothing and relied on the mock server rejecting a stray request, which the callers swallow and log — both now capture the webhook and assert it stayed null.

Filter the verifier check before selecting the newest answer.
filter runs after max, so only the newest bot-authored verified answer is tested for a human verifier. If that newest answer was auto-published (no verifiedBy), the Optional becomes empty even when an older dashboard-verified Iris answer still exists. handleResolutionChange then deletes the thread entry that the older verified answer legitimately owns.
Move the verifier check into the stream filter so the newest dashboard-verified answer is selected.

Requires the matching Pyris changes on
iris/feature/course-wide-memory(ls1intum/edutelligence). Artemis now sendspostIdand per-messageisVerifiedAnswer/resolvesPostflags, which an older Pyris rejects with422. Deploy Pyris first. TheCourseMemoryWeaviate collection also needs to be dropped once so it is recreated with the newpost_idproperty and the thread-based object ids.Motivation and Context
Implements the Artemis side of the Course Memory feature: verified answers from course communication threads are stored in Pyris so recurring questions get a consistent, tutor-backed reply instead of a fresh generation each time.
Pyris owns the pipeline, the Weaviate collection and the retrieval tool. Artemis decides which threads may become memory, which message in a thread is the verified answer, and when an entry must be removed again.
Description
Ingestion plumbing
Mirrors the existing FAQ-ingestion structure:
iris/service/pyris/dto/coursememorywebhook/matching the Pyris wire contract (flat payload, stringified ids,source,isPublicChannel,existingAnswer).CourseMemoryIngestionWebhookJob,PyrisConnectorService.executeCourseMemoryIngestionWebhook→POST /api/v1/webhooks/course-memory/ingest, and a Bearer-validated status endpointwebhooks/ingestion/course-memory/runs/{runId}/status.CourseMemoryIngestionServicebehind aCourseMemoryIngestionApifacade, so the communication module stays decoupled and the whole feature is a no-op when Iris is disabled.The verified answer is stated, not inferred
Pyris used to be told the anchor via a top-level
messageIdand re-derived it by matching againstthread[].id.Postingis a@MappedSuperclass, sopostandanswer_postare separate tables, each with its ownIDENTITYsequence — a root post and one of its answers routinely share a number. When they did, the student's question was tagged as the verified answer and its text was stored as if a tutor had written it.Thread messages now carry the anchor explicitly:
isVerifiedAnswer— the answer whose event triggered this run, at most one.resolvesPost— the durable resolution flags, zero or more, sincePost.resolvedisanyMatch(AnswerPost::doesResolvePost).Ids are namespace-qualified (
post-7/answer-7) so the two namespaces can never collide again, and nothing keys off them.One entry per thread, not per answer
Entries are keyed on the thread root (
postId) instead of the answer message. Previously each resolving answer produced its own near-duplicate entry, and because the extraction prompt forbids using the other resolving answers as an answer source, each one captured only a fragment. A thread with several resolving answers now yields a single canonical Q/A pair merged from all of them; a later correction overwrites in place.conversationIdis kept but corrected: it holds the channel id, not the thread id, and was previously documented and rendered to the agent as the thread.Retraction
Pyris already exposed
POST /api/v1/webhooks/course-memory/delete; Artemis never called it, so un-resolving left Iris serving an answer nobody stood behind. The entry is now removed when the last resolving answer is un-marked, when that answer is deleted, or when the thread itself is deleted.Provenance
sourceIRIS_AUTOIRIS_CORRECTEDTUTOR_WRITTENTHREAD_RESOLVEDTUTOR_WRITTENrequires both the author and the marker to be at least tutor, becausemayMarkAnswerMessageAsResolvingElseThrowlets the root post author — usually a student — mark any answer resolving. Author role alone would let a student promote staff text into the tutor-verified tier.What must never be ingested
NO_AI. The stored question is derived from the thread root, so the opt-out has to block the whole entry rather than redact one message. The same check covers the answer's author. Deletion is deliberately not blocked, so an entry written before someone opted out stays removable.User-visible status
Ingestion is conditional, so a toast fired client-side on the HTTP response would announce an ingestion in every skipped case. Artemis instead pushes
TRIGGEREDover the websocket at the moment it dispatches a webhook, andCOMPLETED/FAILEDwhen Pyris' status callback reports a terminal run state (RUNNINGupdates raise nothing — Pyris emits several per run).CourseConversationsComponentmaps the six operation/stage pairs ontoAlertService. Strings are translated to English and German.Logging
The dispatch and every skip reason now log at
INFOwith the thread and course, so "never triggered" can be told apart from "triggered and silently skipped" — the Pyris side logs the mirror image on webhook receipt.Steps for Testing
