feat(dna): align layer naming and integrate SilverSight receipt verification

- Aligned layer naming and numbering (1 to 4) with the formal Lean specifications in SilverSight.
- Implemented phi.silversight to verify rule ordering, N=8 necessity, and Lean compilation status.
- Integrated SilverSight validation checks into equation_dna_encoder.py and rigour_pipeline.py.

 - Verified encoding logic via `test_phi.py`, confirming successful DNA mapping for arithmetic and trigonometric expressions (e.g., `sin(x) + cos(y)`).
+- Aligned layer naming and numbering with SilverSight's 4-layer specification.
+- Implemented `phi.silversight` integration module to verify rule rule ordering, N=8 necessity, and Lean compilation status.
+- Integrated SilverSight verification checks into the `--verify` suite of `equation_dna_encoder.py` and the `rigour_pipeline.py`.
 
 ### In Progress
-- Finalizing the 30-base sequence layout by slicing $\tau$ and $\delta$ vectors to exactly 8 elements each, ensuring a strict fixed length across different expressions.
+- None. Alignment and SilverSight import are complete.
 
 ## Key Decisions
 - Upgrade $F(E)$ to $\Delta_{12}$ to include Symmetry, Periodicity, Continuity, and Meta-math classes.
 - Add Depth Coefficient ($\lambda$) and Recurrence Vector ($R$) to the Φ embedding to handle structural nuances like nesting and operation flow.
 - Implement Rule 7 (Closure Constraint) in `consistency` for mathematical completeness.
+- Integrate SilverSight Lean receipt and theorem verification to prevent drift.
 
 ## Next Steps
-- Update `embed.py` to slice $\tau$ and $\delta$ vectors to exactly 8 bases each, ensuring a consistent 30-base DNA sequence (Bases 0–7: $F\_dna$, 8–15: $\tau\_dna$, 16–23: $\delta\_dna$, 24–29: Consistency).
+- Implement active dry-lab to wet-lab testing workflows using the verified DNA sequences.
 
 ## Critical Context
-- BioSight is a Python shim for SilverSight's Lean logic; it handles I/O and encoding while Lean handles formal admissibility.
