# Task 1: AI Training Evaluation Persistence Report
|
|
|
|
## Delivered
|
|
|
|
- Added `docs/sql/2026-07-16-ai-training-evaluation.sql`.
|
|
- Creates `ai_training_evaluation` with a unique `(student_user_id, teaching_class_id, task_id)` key.
|
|
- Persists independent help and assessment statuses, task/answer snapshots, reports, raw model responses, model names, completion times, errors, and assessment score.
|
|
- Adds nullable `student_training_answer.ai_assessment_score`.
|
|
- Added `AiTrainingEvaluation`, `AiTrainingEvaluationMapper`, and its MyBatis XML mapping.
|
|
- `findByStudentClassAndTask` retrieves the sole evaluation record for a student, teaching class, and task.
|
|
- `insertIgnore` safely creates the record under concurrent requests.
|
|
- `claimHelp` and `claimAssessment` transition only `NOT_STARTED` or `FAILED` rows to `PROCESSING`.
|
|
- Completion and failure operations update only rows currently in `PROCESSING`.
|
|
- Added `aiAssessmentScore` to `StudentTrainingAnswer`, its XML result/column/dynamic insert/dynamic update mappings, and `updateAiAssessmentScore` for a targeted score write-back.
|
|
- Added the assessment score column to the fresh `student_training_answer` table DDL in `StudentTrainingAnswerServiceImpl`.
|
|
|
|
## Test-first evidence
|
|
|
|
1. Added `AiTrainingEvaluationServiceImplTest` before implementation.
|
|
2. Ran `mvn -Dtest=AiTrainingEvaluationServiceImplTest test` before production changes.
|
|
- Expected RED result: test compilation failed because `AiTrainingEvaluation` and `AiTrainingEvaluationMapper` did not exist.
|
|
3. Implemented the persistence files and re-ran the same targeted Maven test.
|
|
- GREEN result: 3 tests run; 0 failures; 0 errors; 0 skipped.
|
|
|
|
## Verification notes
|
|
|
|
- `git diff --check` completed without whitespace errors.
|
|
- Maven emitted existing project-model warnings about local Aspose `systemPath` dependencies and the relocated MySQL connector artifact. They do not originate from this task and did not prevent compilation or the targeted test from succeeding.
