# Nate — Orchestration Log

**Session:** Stability Bug Investigation Planning  
**Role:** Tester

## Work Performed

- Mapped existing timeout and session lifecycle test coverage across 6 test projects
- Analyzed current regression test boundaries for Power Query, Connection, and PivotTable workflows
- Proposed regression-test-first plan addressing serial workflow gaps
- Identified specific test cases covering post-timeout behavior and reopen/cleanup paths

## Findings

**Existing coverage:** 45+ tests exercise session management, COM cleanup, batch timeout behavior, and lifecycle transitions under controlled conditions. Tests confirm individual components work correctly in isolation.

**Workflow gaps:** 
- Serial Power Query create → refresh → modify → reopen sequence not tested as integrated workflow
- Post-timeout session state recovery not explicitly validated
- Workbook reopen after timeout/failure not covered by current test matrix

**Test priority:**
1. Serial Power Query sequence with same-session recovery (baseline)
2. Timeout behavior during active query operations
3. Cleanup and reopen paths after session failure

## Output

- Test mapping spreadsheet identifying coverage per feature and workflow type
- 3-phase regression test proposal with specific test case names
- Recommended test execution order (baseline → edge cases → recovery)

## Team Updates

- Confirmed explicit timeout requirements for all stability investigation test runs
- Flagged session/batch code paths for COM leak audit during regression test phase
