-### Blockers & Issues
-⚠️ - **Process Issues**: None - agent coordination worked smoothly throughout
-⚠️ - [x] **Document risk assessment matrix** (Est: 25 min) - Create risk ratings for identified issues (Critical, High, Medium, Low)
-⚠️ ### Blockers & Issues
-
-### Immediate Next Steps
-➡️ - Notes: Show per-module coverage changes and remaining gaps

-## Session Resumption Instructions
-
-### 🚀 Quick Start Commands
+**Solution**:
 ```bash
-# Restore session environment
-git checkout feature/dependency-consolidation
-cd plans/tests-audit && ls -la
-git status
-pwd  # Verify working directory
-conda info --envs  # Check active environment
+pip uninstall -y solarwindpy
+pip install -e ".[dev,performance]"
+pytest tests/fitfunctions/test_phase4_performance.py -v
 ```
 
-### 🎯 Priority Actions for Next Session
-1. Review plan status: cat plans/tests-audit/0-Overview.md
-2. Resolve: - **Process Issues**: None - agent coordination worked smoothly throughout
-3. Resolve: - [x] **Document risk assessment matrix** (Est: 25 min) - Create risk ratings for identified issues (Critical, High, Medium, Low)
-4. Review uncommitted changes and decide on commit strategy
+## Bug Fix (COMMITTED e0ca3659)
+File: `solarwindpy/fitfunctions/trend_fits.py`
+- Line 221-223: Filter n_jobs/verbose/backend from kwargs
+- Line 241, 285: Use `**fit_kwargs` instead of `**kwargs`
+
+## Phase 6 Coverage Targets
+| Module | Current | Target | Priority |
+|--------|---------|--------|----------|
+| gaussians.py | 73% | 96% | CRITICAL |
+| exponentials.py | 82% | 96% | CRITICAL |
+| core.py | 90% | 95% | HIGH |
+| trend_fits.py | 80% | 91% | MEDIUM |
+| plots.py | 90% | 95% | MEDIUM |
+| moyal.py | 86% | 95% | LOW |
+
+## Parallel Agent Strategy
+After Stage 2, launch 6 TestEngineer agents in parallel:
+```python
+Task(TestEngineer, "gaussians tests", run_in_background=True)
+Task(TestEngineer, "exponentials tests", run_in_background=True)
+# ... (all 6 modules simultaneously)
+```
+Time: 4-5 hrs sequential → 1.5 hrs parallel
 
-### 🔄 Session Continuity Checklist
-- [ ] **Environment**: Verify correct conda environment and working directory
-- [ ] **Branch**: Confirm on correct git branch (feature/dependency-consolidation)
-- [ ] **Context**: Review critical context summary above
-- [ ] **Plan**: Check plan status in plans/tests-audit
-- [ ] **Changes**: Review uncommitted changes
+## Key Files
+- Plan: `/Users/balterma/.claude/plans/gentle-hugging-sundae.md`
+- Handoff: `plans/fitfunctions-audit/phase6-session-handoff.md`
 
-### 📊 Efficiency Metrics
-- **Context Reduction**: 20.0% (6,856 → 5,484 tokens)
-- **Estimated Session Extension**: 12 additional minutes of productive work
-- **Compaction Strategy**: light compression focused on prose optimization
+## Next Actions
+1. Fix environment (Stage 2)
+2. Verify tests pass
+3. Run coverage analysis (Stage 3)
+4. Launch parallel agents (Stage 4)
