Refine coding standards and testing guidelines. Updated coderule.mdc to emphasize readability, meaningful comments, and scope discipline. Adjusted testing.mdc to set a 75% coverage threshold for business logic and clarified test data requirements. Enhanced tracker.mdc with a mechanism for handling Jira connection issues and added completeness audit steps in research skills.

 **Common mistake**: User asks about "university classroom issues" but sources include policies targeting "K-12 students" — mismatched target populations will invalidate the entire research.
 
+#### Decomposition Completeness Audit (MANDATORY)
+
+After generating sub-questions, verify the decomposition covers all major dimensions of the problem — not just the ones that came to mind first.
+
+1. **Domain discovery search**: Search the web for "key factors when [problem domain]" / "what to consider when [problem domain]" (e.g., "key factors GPS-denied navigation", "what to consider when choosing an edge deployment strategy"). Extract dimensions that practitioners and domain experts consider important but are absent from the current sub-questions.
+2. **Run completeness probes**: Walk through each probe in `references/comparison-frameworks.md` → "Decomposition Completeness Probes" against the current sub-question list. For each probe, note whether it is covered, not applicable (state why), or missing.
+3. **Fill gaps**: Add sub-questions (with search query variants) for any uncovered area. Do this before proceeding to Step 2.
+
+Record the audit result in `00_question_decomposition.md` as a "Completeness Audit" section.

 **Save action**:
 1. Read all files from INPUT_DIR to ground the research in the project context
 2. Create working directory `RESEARCH_DIR/`
