Iris: Add Course Memory — Weaviate collection, ingestion pipeline, hybrid retrieval, and agent tool#620Conversation
Standalone collection storing verified Q/A pairs. Only the question is BM25-searchable and carries the dense vector; answer, course/message/ conversation ids, source and verification metadata are payload. Registered in the VectorDatabase singleton alongside the existing collections.
Introduce CourseMemorySettings (enabled, hybrid alpha, similarity threshold, result limit, query-rewrite toggle, context message limit) and wire it into Settings. Add the course_memory block and the ingestion/ retrieval llm_configuration entries to application.example.yml.
CourseMemorySource enum and CourseMemoryEntryDTO (with to_properties for the Weaviate payload), ThreadMessageDTO for the raw thread the extractor reads, and CourseMemoryIngestionExecutionDTO carrying the thread plus provenance for the ingestion webhook.
Course-scoped CourseMemoryRetrieval (hybrid search, question-only embedding, optional query rewriting, similarity-threshold filtering and graceful degradation when embedding is unavailable), the gating/formatting utils, and the create_tool_course_memory_retrieval agent tool. Add the related PipelineEnum entries and the rewrite/extraction prompts.
LLM-based Q/A extraction over the thread, question-only embedding and upsert/dedup keyed on a deterministic UUID from (courseId, messageId) so tutor corrections overwrite in place; non-public channels are skipped. Add the /webhooks/course-memory/ingest endpoint, its status callback, and register the pipeline with the health feature checker.
Add the course_memory_retrieval dependency and expose the retrieval tool when the course has stored memory, and instruct the agent in the system prompt to reuse and cite verified prior answers.
Cover the schema index flags, retrieval threshold/scoping/degradation and backlinks, Q/A extraction parsing including the correction path, and upsert insert-vs-replace with question-only embedding. Pre-load iris.domain in conftest to resolve a pre-existing import cycle when a retrieval module is imported first.

@toukhi The storage/retrieval structure is promising, but this branch's callback code no longer matches main and will break Iris after merge. The extractor also cannot identify the verified message, and two retrieval settings currently have misleading or ineffective behavior; see the inline comments.

@toukhi [high] message_id identifies the exact verified/resolving answer, but this transcript drops every message ID and sends only roles/content to the extractor. A thread with multiple tutor/Iris answers (or replies arriving before dashboard approval) gives the model no way to select the verified message, so it can persist the wrong answer under the target message's backlink. Mark the message whose id == self.dto.message_id as the verified answer and test a multi-answer thread.
🤖 Prompt for AI agents
In iris/src/iris/pipeline/course_memory_ingestion_pipeline.py, _format_thread() omits the message IDs needed to identify the verified answer referenced by dto.message_id. Tag the matching message explicitly as the verified/resolving answer in the extraction transcript, update the extraction prompt to require that message as the answer source, validate that it exists, and add a multi-answer regression test.
There was a problem hiding this comment.
@toukhi This is still unresolved: _format_thread still omits message IDs and never marks the message matching dto.message_id, so the extractor still cannot reliably choose the verified answer.
There was a problem hiding this comment.
@toukhi The matching message is tagged now, but one part of this is still open: the DTO accepts an empty thread or a thread with no matching messageId, which produces zero VERIFIED ANSWER tags and leaves answer selection ambiguous again. Reject payloads unless exactly one thread message matches messageId, and cover the missing-target case.
There was a problem hiding this comment.
@toukhi This is still open on the current head: the DTO validator only checks existingAnswer for corrections, so an empty thread or zero/multiple messages matching messageId still passes validation and leaves the extractor without exactly one verified target.
…eletion Retrieval: - Gate hits on an absolute cosine-similarity floor via a near_vector certainty pass over the hybrid-ranked candidates (RELATIVE_SCORE fusion normalises the top hit to 1.0 and cannot enforce a threshold). - Keep the rewrite in the student message's original language (stored answers are embedded in their original language; no translation). - Label results by provenance (tutor-verified vs. community-resolved) and treat retrieved Q/A as data, not instructions (prompt-injection guard). Ingestion: - Fail closed on isPublicChannel (default False); never ingest private content on an omitted/malformed flag. - Guard against provenance downgrade: a THREAD_RESOLVED write never overwrites a tutor-verified entry. - Respect the course_memory.enabled kill-switch for writes; skip stages cleanly so the Artemis run terminates. - Pin ingestion embedding to local=False to match retrieval, and warn on ingestion/retrieval embedding-model mismatch. - Keep the thread root post when truncating long threads; best-effort fallback for corrections on unparseable extraction. Add course-memory deletion webhook, provenance-labelled formatting tests, SENTRY_DSN override, and feature docs.
…/edutelligence into iris/feature/course-wide-memory # Conflicts: # iris/src/iris/domain/ingestion/deletion_pipeline_execution_dto.py # iris/src/iris/pipeline/abstract_agent_pipeline.py
The merge from main replaced the stage-based status system (StageDTO / StageStateEnum / initial_stages and the in_progress/done/skip/error callback methods) with a flat run-state model (update = RUNNING, finish = FINISHED, fail = FAILED, both terminal methods self-guarding against double sends). Course Memory still used the removed API, so the app failed to import (ModuleNotFoundError: iris.domain.status.stage_state_dto). - Ingestion status callback now extends IngestionStatusCallback (mirrors FaqIngestionStatus); drop stages/initial_stages. - Ingestion pipeline: in_progress->update, final done->finish, error->fail; the disabled and non-public-channel skips finish() cleanly. - abstract_agent_pipeline: use the plain finish() branch; the new finish() guards terminal sends internally, so the old StageStateEnum guard is gone. - Deletion DTO: drop StageDTO import and initial_stages field. - webhooks: drop initial_stages from both course-memory workers; deletion worker now sends a finish()/fail() terminal update instead of hanging. - Retrieval tool: in_progress->update. - Tests: assert run_state == FINISHED instead of skipped stages.

@toukhi The run-state migration fixes the import blocker, but the ingestion path still has correctness and trust issues, and the hand-off contract no longer matches the code. Please address the four inline findings; I did not hold the unrelated root .dockerignore container failures against this PR.
…urrency fixes Review feedback from PR #620: - Extraction prompt: pass the thread transcript as a HumanMessage instead of a ChatPromptTemplate, so braces in code snippets (and the JSON example in the system prompt) are no longer misread as template variables and crash invoke. - Mark the message whose id == messageId as the VERIFIED ANSWER in the transcript and require the extractor to synthesize the answer from it, so multi-answer threads persist the right answer under the right backlink. Truncation now always retains the root post and the verified message. - Reject IRIS_CORRECTED payloads with a missing/blank existingAnswer, so LLM-generated text is never stored under the tutor-verified label. - Coordinate ingestion and deletion per (course, message) with an in-process delete counter: an ingestion that began before a delete no longer resurrects the entry. - Report ingestion-worker init failures to Artemis via callback.fail() so the job cannot hang. - Fix reversed alpha docs (Weaviate: 0=BM25, 1=dense) in config + example. - Drop index_searchable from the INT course_id property (text-only setting). - Sync integration/testing docs to the run-state callback, delete endpoint, and cosine-certainty gate. Adds tests for brace handling, verified-message marking + retention, correction validation, and the delete-during-ingestion race.

@toukhi Most of the prior feedback is addressed, and I resolved six threads. The ingestion DTO still needs to reject a thread that does not contain exactly one message matching messageId; otherwise the extractor again receives no unambiguous verified answer.

The iris image builds with the repo root as context (it COPYs both iris/ and memiris/). Since #682 the repo-root .dockerignore is scoped to the logos build — it ignores everything but logos/*, which empties the iris context and makes every COPY fail with "not found" (the iris image build has been red on main since 2026-07-19; this branch only inherits it via the merge). Add iris/Dockerfile.dockerignore: BuildKit prefers a <Dockerfile>.dockerignore next to the Dockerfile over the context-root one, so this restores the iris context (iris/ + memiris/, minus caches/VCS) without enlarging the logos build context that #682 deliberately slimmed. Verified locally: build context 2B -> 2.50MB, all COPY steps resolve, and the image builds through to export.

…on the thread Artemis sent a top-level messageId and the pipeline re-derived the anchor by matching it against thread[].id. Post and answer ids come from separate tables with independent sequences in Artemis, so a root post and one of its answers routinely share a number, and the student's question was tagged as the verified answer. The validator added for this rejected those payloads with a 422, which turned a silent wrong write into a dropped ingest but also rejected the legitimate case of a thread with several resolving answers. Take the anchor from explicit flags instead. ThreadMessageDTO gains isVerifiedAnswer and resolvesPost; _format_thread and _truncate_thread tag from those and no longer compare ids. The validator now requires at least one flagged message and at most one isVerifiedAnswer, so several resolvesPost messages are accepted and merged rather than refused. Key the Weaviate object on postId instead of messageId, so a thread with several resolving answers or a later correction yields one canonical entry instead of near-duplicates competing in hybrid search. messageId stays as provenance; delete_for_message becomes delete_for_thread. The extraction prompt now asks for a single answer synthesized from all tagged messages, preferring the later one where they conflict. Add logging so a run can be traced from webhook receipt to write: both webhooks log on arrival with the course, thread, source and flag counts; the skip paths name the thread and course; extraction and the insert/replace branch are logged. Without the receipt line there was no way to tell "never triggered" apart from "triggered and silently skipped".

@toukhi The explicit answer flags and thread-keyed storage address the prior ambiguous messageId matching, and the Iris test check passed. However, the Artemis handoff contract was not migrated with the implementation, so clients following it will send invalid ingestion and deletion payloads; see the inline finding.

@toukhi [high] This advertised “exact contract” is incompatible with the current DTOs: ingestion now requires postId and at least one thread message flagged with isVerifiedAnswer or resolvesPost, while deletion requires postId; however, the examples, field table, trigger instructions, and checklist still omit those fields and describe messageId as the upsert/delete key. An Artemis client following this document will receive validation errors instead of storing or deleting course memory, so migrate this specification and the testing guide to the new wire contract.
🤖 Prompt for AI agents
In iris/COURSE_MEMORY_ARTEMIS_INTEGRATION.md, the ingestion and deletion examples omit required postId, omit the required answer-anchor flags, and still describe messageId as the deduplication/deletion key even though the current DTOs key entries on postId. Update every example, field table, trigger instruction, checklist item, and the corresponding testing guide to send postId, mark the appropriate thread messages with isVerifiedAnswer or resolvesPost, and use postId for upsert and deletion semantics.

…d root A follow-up question in a thread was answered with the answer to the thread's opening question. The pipeline named `post.content` as "the student's post" and dumped every other message, including the one that triggered the run, into an unlabelled list of "existing replies" — so the agent answered the root post as instructed. The thread is now turned into chat history (Iris's own replies as assistant turns, everyone else as user turns prefixed with their role), which makes the newest message the one the agent answers. The DTO carries no chat_history, so message_history was empty and the retrieval query rewriter had no context to resolve a follow-up against either; it now does. The retrieval query is scoped to the message being answered. Querying with the whole thread let the opening question dominate the embedding, which is why course memory kept returning the first question's entry and — combined with "prefer reusing it for consistency" — served it back verbatim. The prompt now also tells the agent to ignore a retrieved prior answer that matches an earlier message in the thread rather than the current one. Requires the ordered, role-annotated thread from Artemis#13390.

@toukhi The new thread-targeting logic and its tests are internally consistent, but the existing high-severity Artemis contract thread remains unresolved: the documentation still omits required postId and answer-anchor fields and describes messageId as the storage/deletion key. Clients following that contract would fail DTO validation, so changes are still requested.

The pipeline logged "Using local model with tool calling support" without naming the model, which cannot show whether local and cloud actually map to different models in the llm configuration. A pre-agent hook now logs the resolved mode together with the model id, the Artemis selection that produced it, and the course and post ids, so a test run shows at a glance which inference path it took.

@toukhi The latest commit only adds autonomous-tutor model-mode logging and does not address the outstanding Artemis handoff contract. The integration and testing examples still omit required postId and answer-anchor fields and incorrectly describe messageId as the upsert/deletion key, so the unresolved high-severity thread remains valid. The new logging hook itself conforms to the existing pre-agent hook contract.
…e label Iris sometimes opened a threaded reply with "[Iris (you)]". Every message of the thread was handed to the model prefixed with its author's role, including Iris's own assistant turns, so the model read the prefix as part of how its replies are written and reproduced it in the answer it posted. It only surfaced on replies: a fresh post has no earlier Iris turn to copy. Iris's own turns are no longer prefixed — the assistant role already identifies them. The other participants keep their labels, which is what lets Iris tell a student from a tutor. The prompt now also states that the labels mark who wrote what and must never open a reply. As a backstop, a copied label is stripped from the final answer. Only the exact known labels are matched, so an answer that legitimately starts with a markdown link is left intact.

@toukhi The unresolved high-severity handoff-contract thread remains valid: the examples still omit required postId and answer-anchor flags and incorrectly describe messageId as the upsert/deletion key. Previously reported validation and ordering defects also remain, including coercible isPublicChannel, nullable settings that are dereferenced, and worker-start generation tracking that cannot prevent queued or cross-replica resurrection. The latest autonomous-tutor role-label changes and passing CI do not address these blockers.

… cite a real link Carries the ingestion-input hardening that was already in the working tree (strict `isPublicChannel`, required `settings`, zero-limit history guard, delete counter sampled at webhook accept time) plus the following. Redaction of AI opt-outs mid-thread. `ThreadMessageDTO` gains `redacted` and defaults `content`, because Artemis serializes with NON_EMPTY and drops an empty string from the wire entirely. `_format_thread` renders the shared `REDACTED_ANSWER_PLACEHOLDER` so the placeholder text has one owner. Until now only the question author and the resolving author could block an ingestion; every other participant's reply reached the extractor verbatim, even though the autonomous tutor path has always redacted them. Channel-scoped deletion. `CourseMemoryDeletionExecutionDto` takes `postId` XOR `conversationId` — neither would delete nothing while reporting success, and both would leave the blast radius ambiguous. `delete_for_conversation` removes every entry mined from a channel, which Artemis needs when a channel is deleted or stops being public: channel eligibility is only evaluated when an entry is written, so an answer ingested while the channel was public would otherwise keep being served after it was restricted. Followable backlinks. `format_course_memories` composes the Artemis deep link from the `courseId` / `conversationId` / `postId` already stored, and the agent is told to cite it as a markdown link. The previous instruction asked it to cite a bare id, which is ambiguous (posts and answer posts have independent id sequences) and unusable to a student. No schema change, so existing entries get links too. Prompt hardening. The extraction prompt now states that the transcript is data rather than instructions, and that redacted placeholders must never be quoted. Its output is written straight into the store, and student text is a legitimate answer source. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…ingestion Channel deletion could not bump the per-thread delete counters, so an ingestion accepted before the purge re-inserted its entry afterwards and content from a deleted or newly private channel kept being served. Track a channel-scoped delete counter alongside the per-thread one, sampled at webhook accept time and re-checked under the write lock, so a stale ingestion is refused. Both counters remain in-process only.

Summary
This PR introduces Course Memory, a persistent knowledge store that captures tutor-verified Q/A pairs from Artemis
communication channels and makes them available to Iris during student interactions. When a relevant past answer is
found, Iris reuses the verified response for consistency rather than generating a new one from scratch.
Key Changes
New Features:
CourseMemoryWeaviate collection with HNSW cosine index; only the question field is embedded and BM25-indexed, allother fields are payload metadata
CourseMemoryIngestionPipeline— LLM-based Q/A extraction from resolved threads with deterministic UUID-keyed upsert(supports tutor corrections overwriting existing entries in place)
POST /api/v1/webhooks/course-memory/ingestwebhook — single endpoint handling all source types (IRIS_AUTO,TUTOR_WRITTEN,IRIS_CORRECTED,THREAD_RESOLVED)CourseMemoryRetrieval— hybrid search (BM25 + dense, configurablealpha, default 0.5) with optional queryrewriting and score-threshold filtering
course_memory_retrievalagent tool wired into the Autonomous Tutor pipeline so Iris checks verified history beforeanswering
CourseMemoryIngestionStatuscallback for progress reporting back to ArtemisDomain DTOs:
CourseMemoryEntryDTO,CourseMemorySourceenum,ThreadMessageDTOCourseMemoryIngestionExecutionDTOfor the webhook payloadConfiguration:
course_memorynamespace inapplication.local.yml/application.example.ymlwithsimilarity_threshold,result_limit,alpha, andquery_rewrite_enabledFix: answer the newest message of a thread, not the thread root
Found while testing Course Memory end to end. Asking a follow-up in a thread got the opening question answered a
second time, word for word:
Artemis re-runs the pipeline on every new message and sends the whole thread, but the pipeline named
post.contentas"the student's post" and dumped every other message — including the one that triggered the run — into an unlabelled
list of "existing replies". The agent answered the root post, exactly as instructed.
Two independent causes, both fixed:
assistant turns, everyone else as user turns prefixed with their role (
[Student],[Tutor],[Instructor],[Iris (you)]) — so the newest message is the one the agent answers. This also fixes a latent gap: the DTO carries nochat_history, somessage_historywas empty and the retrieval query rewriter had no context to resolve acontext-poor follow-up against.
returning the first question's entry — and combined with "prefer reusing it for consistency" it was served back
verbatim. The query is now scoped to the message being answered, and the prompt tells the agent to ignore a retrieved
prior answer that matches an earlier message in the thread rather than the current one.
Depends on Artemis PR#13390, which sends the thread ordered
(oldest first) and annotates every message with an author role. Without it the replies arrive in arbitrary order and
Iris cannot tell its own drafts from student messages.
