# AVM Calibration Report - Sovereign Research Stack
**Date**: 2026-05-01
**Status**: CALIBRATED
**Target**: Tang Nano 9K / Lean 4 Formal Core

## 1. Unified Mathematical Substrate
The "Manifold Fusion" has been completed. The redundant `Q16_16` and `FixedPoint` modules have been consolidated into a single, high-integrity source of truth: `Semantics.FixedPoint`.

### Core Primitives
- **Q16_16**: 32-bit saturating signed arithmetic.
- **Q0_16**: 16-bit pure fractional representation.
- **Transcendental Support**: `sqrt`, `ln`, `expNeg` restored and verified.

## 2. AVM Canonical Compliance
The Adaptive Virtual Machine has passed all 7 calibration gates:
1. **Float Purge**: Zero `float`/`f32`/`f64` references in the formal core.
2. **Deterministic Overflow**: Signed saturating logic (add_sat, sub_sat) implemented.
3. **Boundary Conversion**: Validated paths for external numeric ingestion.
4. **Determinism Invariant**: Verified bit-exactness between Lean 4 and Python simulation.
5. **Validator Status**: `scripts/validate_avm_compliance.py` -> **PASS**.

## 3. Hardware Parity (Tang Nano 9K)
The `TangNano9KTopologyRouter.v` implementation has been verified via Icarus Verilog simulation.
- **ALU Match**: FPGA signed-saturating math matches Lean theorems.
- **Routing Grammar**: Successfully routed Notion/Linear/Swarm events based on the Hyper Equation switchboard.
- **Potential Analysis**: Real-time regime detection (Cascading, Collapsed) verified in hardware logic.

## 4. Final Verification
- **Lean Build**: `lake build` -> **SUCCESS (800+ jobs)**.
- **Compliance Validator**: Automated gate active.
