Feagi-EVO Compatibility Fixes Needed

This document outlines the compilation errors in feagi-evolutionary that need to be fixed to work with the updated feagi-data-processing API.

Summary of Changes in feagi-data-processing​

  1. CorticalArea:

    • ❌ Removed AreaType enum → Use CorticalAreaType instead
    • ✅ Changed position: (i32, i32, i32) → position: GenomeCoordinate3D
    • ✅ Using HashMap<String, Value> for properties (flexible approach)

  2. BrainRegion:

    • ❌ Removed RegionType::Custom → Use RegionType::Undefined
    • ✅ Changed region_id: String → region_id: RegionID (UUID-based)
    • ✅ Changed cortical_areas: HashSet<String> → HashSet<CorticalID>
    • ✅ Properties now use struct instead of HashMap

Required Fixes in feagi-evolutionary​

File: src/genome/parser.rs​

Fix 1: Update Import​

Line 50:

// Before:
use feagi-data-structures::genomic::cortical_area::{CorticalAreaDimensions as Dimensions, CorticalArea, AreaType};

// After:
use feagi-data-structures::genomic::cortical_area::{CorticalAreaDimensions as Dimensions, CorticalArea};
// Remove AreaType - it no longer exists

Fix 2: Convert Position Tuple to GenomeCoordinate3D​

Line 334:

// Before:
position,

// After:
GenomeCoordinate3D::new(position.0, position.1, position.2),
// Or if position is (x, y, z):
position.into(), // If Into trait is implemented

Fix 3: Fix RegionType​

Line 451:

// Before:
let region_type = RegionType::Custom;

// After:
let region_type = RegionType::Undefined;

Fix 4: Convert String to RegionID​

Line 454:

// Before:
region_id.clone(),

// After:
RegionID::from_string(&region_id)?, // If parsing from string
// Or:
RegionID::from_string(region_id.as_str())?,

Fix 5: Use CorticalID instead of String​

Line 465:

// Before:
region.add_area(cortical_id.as_base_64());

// After:
region.add_area(cortical_id); // Use CorticalID directly

Fix 6: Use Property Setters for BrainRegion​

Line 478, 481, etc:

// Before:
region.properties.insert("description".to_string(), serde_json::json!(desc));
region.properties.insert("coordinate_2d".to_string(), serde_json::json!(coord_2d));

// After:
region.set_description(desc);
region.set_coordinate_2d(GenomeCoordinate2D::new(x, y));

File: src/templates.rs​

Fix 1: Update Import​

Line 18:

// Before:
use feagi-data-structures::genomic::cortical_area::{CorticalAreaDimensions, CorticalArea, AreaType};

// After:
use feagi-data-structures::genomic::cortical_area::{CorticalAreaDimensions, CorticalArea};

Fix 2: Convert Position Tuple​

Lines 72, 83:

// Before:
(0, 0, -10),

// After:
GenomeCoordinate3D::new(0, 0, -10),

Fix 3: Fix Properties Assignment​

Lines 71, 93:

// Before:
area.properties = props; // where props is HashMap<String, Value>

// After:
// Properties are already HashMap, so direct assignment should work
// But verify the structure matches

Quick Reference: New Types​

Imports Needed​

use feagi-data-structures::genomic::descriptors::{GenomeCoordinate2D, GenomeCoordinate3D};
use feagi-data-structures::genomic::brain_regions::{BrainRegion, RegionID, RegionType};
use feagi-data-structures::genomic::cortical_area::{CorticalArea, CorticalID, CorticalAreaType};

Type Conversions​

String → RegionID​

let region_id = RegionID::from_string("root")?;
// Or for UUID strings:
let region_id = RegionID::from_string(uuid_string)?;

(i32, i32, i32) → GenomeCoordinate3D​

let coord = GenomeCoordinate3D::new(x, y, z);
// Or:
let coord: GenomeCoordinate3D = (x, y, z).into(); // If trait implemented

String → CorticalID​

// For base64:
let cortical_id = CorticalID::try_from_base_64(base64_string)?;
// For bytes:
let cortical_id = CorticalID::try_from_bytes(&byte_array)?;

Notes​

  • CorticalArea properties remain HashMap<String, Value> for flexibility (see PROPERTIES_STRUCT_MIGRATION_PROPOSAL.md)
  • BrainRegion properties now use typed struct - must use setters
  • All coordinate positions must use typed coordinate structs
  • Region IDs are now UUIDs instead of strings
