### ⚠️ Uncertain / Not Found

1. **SLOS Classical-Sim Disclaimer** — Not explicitly found
   - File header mentions "exact integer verification"
   - No explicit disclaimer about classical simulation limitations
   - **Action needed:** Add disclaimer to script header

2. **Container (silver-autoproof:latest)** — NOT REQUIRED
   - MCP autoproof infrastructure already exists and is functional
   - Python MCP server: `scripts/mcp_autoproof.py` (282 lines)
   - Python worker: `scripts/mcp_worker.py` (127 lines)
   - Rust backend: `scripts/mcp_backend/` (thread-safe state management)
   - Uses neon-64gb API (http://100.92.88.64:8766/generate) for phi4 LLM
   - File-based locking for thread safety
   - Supports stdio and HTTP modes
   - **Action needed:** Document infrastructure in README or separate doc

3. **Adversarial Review Count Discrepancy**
   - Session summary mentions "14 issues"
   - Review document shows 18 findings (4+5+6+3)
   - **Action needed:** Clarify count (may be different categorization)

4. **TOROIDAL_POLOIDAL_REFINEMENT.md** — Planning document only
   - 6 refinement actions (R1-R6) all marked TODO or BLOCKED
   - No implementation yet
   - **Action needed:** Prioritize and implement

---

## Next Steps (Prioritized)

### Immediate (Low Effort, High Impact)

1. **Add SLOS Disclaimer** (15 min)
   - Add to `photonic_sidon_search.py` header
   - Clarify classical vs quantum simulation
   - Document empirical nature of Omega-Sidon correlation

2. **Clarify Adversarial Review Count** (10 min)
   - Check if "14 issues" refers to unique issues vs total findings
   - Update session summary or review document for consistency

3. **Document Container Status** (20 min)
   - If silver-autoproof exists in another branch/repo, document location
   - If not, create Dockerfile based on current autoproof infrastructure
   - Update README with container usage instructions

### Short-term (Medium Effort, Research Value)

4. **Run Sidon-Sofa Coloring v3** (2-4 hours)
   - Generate artifacts for fine q-sweep + n=34
   - Analyze q=1 phase boundary behavior
   - Compare with v2 results

5. **Verify Photonic Search Reproducibility** (30 min)
   - Confirm all 18 tests still pass
   - Check test evidence matches committed version

6. **Address TOROIDAL_POLOIDAL_REFINEMENT.md TODOs** (4-8 hours)
   - **R1 (High):** Redefine modulus selection as q-profile design
   - **R2 (High):** Add cross-pair q-ratio coprimality check
   - **R4 (Medium):** Document 1.9× optimum as A2 sweet spot
   - **R5 (High):** Formalize discrete Elsasser decomposition

### Medium-term (High Effort, Strategic Value)

7. **Formalize Discrete Elsasser Decomposition** (1-2 days)
   - Extend CRTSidon.lean with toroidal/poloidal coordinate system
   - Prove equivalence between CRT embedding and Elsasser decomposition
   - Connect to plasma physics literature (Elsasser 1946)

8. **Implement q-Profile Design** (2-3 days)
   - Refactor modulus selection to use q-profile (q = L₂/L₁)
   - Systematic sweep: q ∈ {0.5, 0.75, 1.0, 1.33, 2.0}
   - Analyze Sidon preservation as function of q
   - Identify optimal q-regime (conjectured: q < 1, poloidal-dominated)

9. **Create silver-autoproof Container** (1 day)
   - Dockerfile based on `scripts/mcp_autoproof.py`
   - Include Lean 4 toolchain + Mathlib
   - Expose MCP server endpoint for remote proof filling
   - Update CI/CD to use container for automated proof checking

### Long-term (Research Directions)

10. **Extend to Larger Sidon Sets** (ongoing)
    - Current: n ≤ 34 (v3 script)
    - Target: n = 50, 100, 200
    - Requires GPU acceleration or distributed computation

11. **Quantum Photonic Simulation** (exploratory)
    - Replace classical SLOS with quantum circuit simulation
    - Test if quantum Omega shows stronger Sidon correlation
    - Requires Quandela API access (key already encrypted)

12. **Connect to Hadwiger-Nelson Problem** (theoretical)
    - Use Sidon-Sofa coloring results to bound χ(ℝ²)
    - Current lower bound: χ ≥ 5 (de Grey 2018)
    - Can Sidon structure improve this?
