Q16_16 Unification Migration Plan
|
|
=================================
|
|
|
|
PROBLEM:
|
|
There are 6 different Q16_16 type definitions causing fragmentation:
|
|
1. Semantics.FixedPoint.Q16_16 (canonical - Int subtype) - Used by ~421 files
|
|
2. Semantics.PhysicsScalar.Q16_16 (UInt32) - Used by 27 files
|
|
3. Semantics.ElectromagneticSpectrum.Q16_16 (UInt32) - Used by 17 files
|
|
4. external/OTOM/FixedPoint.Q16_16 (struct UInt32) - Standalone
|
|
5. Semantics.RcloneIntegration.Q16_16 (struct Int) - 3 files
|
|
6. Semantics.MetaManifoldProver.Q16_16 (Int) - 0 files
|
|
|
|
APPROACH:
|
|
Phase 1: Create compatibility bridge (DONE - PhysicsScalarBridge.lean created)
|
|
Phase 2: Migrate PhysicsScalar consumers (27 files)
|
|
Phase 3: Migrate ElectromagneticSpectrum consumers (17 files)
|
|
Phase 4: Eliminate duplicate definitions
|
|
|
|
RISK:
|
|
Semantic incompatibility - PhysicsScalar uses unsigned arithmetic, FixedPoint uses signed.
|
|
The bridge conversion is lossy and behavior may differ.
|
|
|
|
TIMELINE:
|
|
Significant undertaking - each file 1-4 hours for careful proof verification. |
