…ve smoke Filled the runbook's Observed section with the actual callback captured from a live run (cloud gpt-5-mini + Weaviate): the authoritative active decision (confidence 0.85) and the trailing duplicate. Confirms the flat action/result/confidence/rationale shape matches the Artemis-side StruggleInterventionStatusUpdateDTO.
…current code - Require the structured anchor+inlineHint whenever a single concrete line is the locus; a concrete file/line must never live only in the prose message, so the editor can render the inline cue at the exact spot. - Tell the gate its sources can disagree: the code is the student's current working copy (uncommitted edits merged on the last submission), but the build logs and test feedback come from the last submitted build and may be older. Verify a compile error in the current code before raising it; if it is already fixed, stay silent instead of relaying a stale error.
…itted diff tool Render tri-state feedback (PASS / FAIL / NOT EXECUTED) so unexecuted tests are never shown as failures. Add a local_vs_submitted_diff tool (registered for confirm_close only) over the committed code Artemis now ships, which distinguishes a real diff, "no changes since the submission", and "submitted code could not be read". Rework the confirm_close prompt to treat passing real tests for the flagged area as decisive rather than defaulting to doubt, and to reference tools only when available (no submission -> judge from the signal alone).
Its purpose (capturing the real callback body so the Artemis side could assert against the actual shape) is long fulfilled by the integration tests, and the test_ prefix made it look like a pytest module.
…s now sBase The client removed the V(t) telemetry curve; StruggleTick loses v, summarize_signal renders the s-trajectory and labels severity as s.
The decide template never rendered the episode's prior hints (the client sends them on every request) and only carried a soft do-not-repeat sentence, so re-alerts during a live episode produced the same hint reworded at high confidence (observed live: 4x the same stub diagnosis). The prompt now lists the episode's delivered hints, explains the '(proactive hint, ...)' history tags, and carries a standing HARD RULE: substantively the same diagnosis as any delivered hint (this episode or tagged history) means action silent; rewording counts as repeating. A recovery EXCEPTION keeps a genuinely returned problem hintable again.
The desktop client only ever sends intent in {decide, confirm_close}, so
the server-side stale_check pipeline mode and its ask/question status
fields are unreachable. Drop the StaleCheckResult parser, the stale_check
template and its wiring in build_system_message/post_agent_hook, the
ask/question fields on the status-update DTO, and the stale_check intent
literal, plus the related tests. The decide and confirm_close paths are
unchanged.
The client engine's discrete test-stagnation path now reports primaryBoundary=TPS with path=discrete on the struggle signal. Widen the signal DTO literals accordingly and gloss the TPS boundary in summarize_signal, so the decide and confirm_close prompts explain the trigger semantics (several consecutive builds without passing any new test - stalled, regressed, or failing outright) to the LLM, which cannot infer them from the boundary code alone. Edit-path boundaries stay unglossed.
…diff The decide (hint) path had no signal of which method the student is editing, so the anchor was chosen purely from failing-test evidence and could land on a method the student was not working on (observed: a hint on an untouched calculateOptimalPayment stub while the student was fixing findLatestCompatible, itself still failing). Un-gate the existing local_vs_submitted_diff tool so it is available on decide too (it was confirm_close-only); the changed code region it reveals is the student's current focus. Add a soft, subordinate focus/redirect rule to the decide prompt: prefer to help in the focus method when it is itself failing, redirect to another method only when the focus method already looks correct (and then frame the redirect explicitly), and fall back to the dominant blocker when there is no focus signal. The rule stays under the existing no-repeat and current-code-confirmation rules. Generalise the diff tool docstring for this dual use and note that an all-removed hunk is ambiguous, not a deletion. Pyris-only: the extension already sends the working copy and Artemis already builds both repo versions on decide, so the diff tool's inputs are present; only the intent gate withheld it.
…ethod The confirm-close prompt kept an episode open whenever a test in the flagged topic still failed, even after the flagged method was already fixed. Add a method-level attribution rule: hold the episode open only when the flagged method itself still shows the defect; related tests failing because of a separate or unimplemented method (e.g. a stub returning a constant) no longer keep it open.
The struggle-intervention pipeline now receives proactivity_mode (pull/push, default push) and passes it to the decide system prompt: pull leans reticent, push may reach out. Tone only; the hard Pull cap (active -> ambient) is enforced in Artemis, not by the LLM.
…eat, never silent)
… (trajectory carries sBase) StruggleSignal loses dominant_components (and the ComponentName/StruggleComponent types); the pipeline prompt no longer lists component breakdowns and now labels the severity/trajectory values sBase so the LLM never learns a signal name that no longer exists. The trajectory tick's JSON/model field name stays "s" - only the prompt wording changes. The model has no extra="forbid", so a payload that still carries dominantComponents is silently ignored rather than rejected with 422, which the new tolerance test in test_struggle_signal_dto.py locks in.
The client engine no longer emits FM_PLUS (improved-but-still-failing build); the boundary set is now FM, E4, N1, STATE plus discrete TPS. Tightening the Literal makes Pyris reject a stale FM_PLUS payload with a 422.
Brings in the Pyris streaming work (partial results, run state, activities), which replaced the stage-based status API the struggle-intervention pipeline was written against. Ported to the new API: - StruggleInterventionCallback now follows the upstream callback shape (url, run_id, DTO with run_state=RUNNING); initial_stages and the synthetic Thinking stage are gone with the stage machinery. - cb.done(...) -> cb.finish(...), final_result -> result. - callback.error(...) -> callback.fail(...), matching the other workers. - file_lookup_numbered and local_vs_submitted_diff no longer call the removed callback.in_progress; tool progress is reported by the activity system. - Tests updated accordingly (328 passing).
…on files Wrap two over-long string literals, add the missing class docstring on ProgrammingSubmissionDTO and drop the redundant function-local reimports of SimpleNamespace and MagicMock, which are already imported at module level.

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to If Artemis sends the established camelCase field, pull-mode requests can silently default to push and produce more proactive interventions than intended. This is a bounded integration issue requiring owner awareness or follow-up, but it is not shown to be release-blocking. Sequence Diagram(s)sequenceDiagram

- Around line 19-36: Update the proactivity_mode field in the DTO to accept the
camelCase proactivityMode alias, matching the payload convention used by the
other aliased fields. Add or update coverage to verify a camelCase payload
populates proactivity_mode with the supplied value instead of defaulting to
"push".

- Line 184: Update the terminal callback in StruggleInterventionPipeline to pass
state.tokens instead of the separate empty self.tokens list, and include the
gate confidence through the accepted confidence field. Ensure post_agent_hook
emits the terminal update only after these values are supplied, avoiding a later
duplicate state.tokens finish.

post_agent_hook sent the terminal status with self.tokens, which is set to an empty list in __init__ and never appended to. AbstractAgentPipeline accumulates LLM usage in state.tokens and finishes with it afterwards, but StatusCallback.finish rejects a second terminal send, so that later call was dropped and the usage never reached Artemis. Use state.tokens in post_agent_hook, where the state is in scope. The handler in __call__ keeps self.tokens because the exception is caught outside the agent run and no state exists there.

Motivation and Context
Part of the Iris proactive struggle intervention feature: when the VS Code client detects that a student is stuck on a programming exercise, Artemis forwards a struggle signal and exercise context to Pyris, which must decide whether and how to intervene without spoiling the solution.
This is the Pyris pipeline for that decision. Thesis work in progress; pairs with the server (ls1intum/Artemis#13023) and the client (ls1intum/artemis-extension#335).
Description
The pipeline.
StruggleInterventionPipeline, registered as thestruggle_intervention_pipelineLLM config and wired as a route with a singledefaultvariant. The gate decidessilent/ambient/activewith an optional inline anchor + hint; results are type-validated and the confidence is clamped.Three prompts, not one, because the pipeline serves three distinct moments:
struggle_intervention_system_prompt.j2struggle_help_request_system_prompt.j2struggle_confirm_close_system_prompt.j2Presence level reaches the prompt. The execution DTO carries
proactivity_mode: Literal["pull", "push"], defaulting topush. Inpullthe system prompt switches to a reticent tone. Artemis independently enforces the same mode by downgradingactivetoambient, so the tone change here is about how Iris speaks, not about whether it is allowed to.Three new tools the gate can call to ground its decision in what the student actually did, rather than in the signal alone:
feedbacks— retrieves automated test feedbackfile_lookup_numbered— afile_lookupvariant prefixing 1-based line numbers, so the model can name an anchor line the client can actually jump tolocal_vs_submitted_diff— diffs the live working copy against the last submissionDTOs and transport. Struggle-intervention execution and status-update DTOs, the episode and signal DTOs, and the callback back to Artemis.
Tests. Nine new test modules covering the route, the execution DTO, the signal DTO, the status-update DTO, the callback, the pipeline itself, and each of the three tools.
Steps for Testing
Prerequisites: a configured Pyris (
application.local.yml+ an LLM inllm_config.local.yml), a running Weaviate, and Artemis with the struggle endpoint (ls1intum/Artemis#13023).pyrisis healthy from Artemis (GET /management/healthshows the pipeline configs valid).POST .../struggle-intervention).StruggleInterventionPipeline (variant=default), calls the configured LLM, and posts a status callback to Artemis withaction∈ {silent,ambient,active}, an optionalanchor_file/anchor_line/inline_hint, and aconfidence.silentdecision surfaces nothing, whileambient/activeproduce a hint.proactivity_mode: "pull"and confirm the reticent tone in the generated hint.iris/tests/test_struggle_*andtest_*_toolmodules cover the route, DTOs, callback, pipeline and tools.Screenshots
Supersedes #640. Same work, moved from the fork branch to an upstream branch.
