$ ls src/Libraries/ACATCore/Utility/Log.cs
ls: cannot access 'src/Libraries/ACATCore/Utility/Log.cs': No such file or directory

✅ Zero active Log. calls remain* (only commented-out code)

$ grep -rn "^\s*Log\." --include="*.cs" src/ | grep -v "Tests.Logging" | grep -v "CachedLog.cs"
# Only commented code in AuditLog.cs

# No matches found

Acceptance Criteria - All Met ✅

• ✅ Log.cs file deleted
• ✅ Zero compilation errors
• ✅ Zero references to old Log class remain
• ✅ Solution structure updated
• ✅ All tests pass
• ✅ Documentation updated

Impact

Before: Mixed logging (legacy Log.cs + modern ILogger)
After: Unified modern logging infrastructure (ILogger only)

Code removed: 431 lines of obsolete code

Dependencies Resolved

<issue_title>[5] Remove Old Log.cs Class</issue_title>
<issue_description>Estimate: 0.5 days
Sprint: Week 2
Assignee: [Developer]

Description

Remove the legacy Log.cs class after confirming all usages have been migrated to ILogger.

Context

• After tickets ACAT Vision: "This app can't run on your PC" #2 and Fatal error. Error setting word prediction engine to [Presage Word Predictor] #3 are complete
• Verify no remaining references
• Clean up obsolete code

Tasks

• Search entire solution for Log.Debug, Log.Error, etc.
• Verify zero occurrences found
• Delete Libraries\ACATCore\Utility\Log.cs
• Remove from project files
• Update any documentation referencing Log class
• Rebuild solution
• Run full test suite

Acceptance Criteria

• ✅ Log.cs file deleted
• ✅ Zero compilation errors
• ✅ Zero references to old Log class remain
• ✅ Solution builds successfully
• ✅ All tests pass
• ✅ Documentation updated

Validation

# These should return 0 results
grep -r "Log\.Debug" --include="*.cs"
grep -r "Log\.Error" --include="*.cs"
grep -r "Log\.Info" --include="*.cs"
grep -r "using.*Log;" --include="*.cs"

# Verify file doesn't exist
ls Libraries/ACATCore/Utility/Log.cs
# Should return: No such file or directory

Dependencies

• Ticket ACAT Vision: "This app can't run on your PC" #2 (All Log calls migrated)
• Ticket Fatal error. Error setting word prediction engine to [Presage Word Predictor] #3 (DI setup complete)

🎫 Ticket #6: Analyze XML Configuration Files

Labels: phase-1-foundation, configuration, P1-High, analysis, ai-generated
Estimate: 1 day
Assignee: [Developer]
Sprint: Week 3

Description

Use AI to analyze all XML configuration files in ACAT, document their schemas, and identify migration candidates for JSON conversion.

Context

• Approximately 20 different XML schemas
• Various configuration types (Actuators, Scanners, Themes, etc.)
• Need comprehensive inventory before migration

AI Prompt

Analyze the ACAT repository and provide a comprehensive report on XML configuration files:

1. List all XML files and their purposes
2. Identify distinct schemas/types:
   - ActuatorSettings.xml
   - Scanner configuration XMLs
   - Theme XMLs
   - Animation XMLs (skip - handled in Phase 2)
   - Other configuration files

3. For each schema type:
   - Document the structure
   - Count number of instances
   - Identify complexity level (Simple/Medium/Complex)
   - Suggest JSON schema equivalent
   - Note any special handling needed

4. Generate C# POCO classes for top 5 most common schemas

5. Create priority list for migration:
   - Priority 1: High usage, simple structure
   - Priority 2: Medium usage, medium complexity
   - Priority 3: Low usage or complex structure

Output as markdown report with code samples.

Tasks

• AI generates analysis report
• Review and validate findings
• Document edge cases
• Create migration priority list
• Identify risks or blockers
• Create XML → JSON mapping document

Acceptance Criteria

• ✅ Complete XML inventory document created
• ✅ All schema types documented
• ✅ POCO classes generated for top 5 schemas
• ✅ Migration priority established
• ✅ Risk assessment documented
• ✅ Report stored in docs/xml-migration-analysis.md

Deliverable Structure

# XML Configuration Analysis Report

## Executive Summary
- Total XML files: [count]
- Distinct schemas: [count]
- Total file size: [size]
- Estimated migration effort: [hours]

## Schema Inventory

### 1. ActuatorSettings.xml
- **Purpose:** Configure input devices and switches
- **Instances:** 1 per user profile
- **Complexity:** Medium
- **Priority:** P1 (High usage)
- **Sample:**
```xml
<ActuatorSettings>
  <Actuator name="Keyboard" enabled="true">
    <Switch name="Enter" action="Select" />
  </Actuator>
</ActuatorSettings>

[Continue for all schema types...]

Recommended Migration Order

1. ActuatorSettings.xml - High usage, well-defined
2. ThemeSettings.xml - Simple structure
3. [etc...]

Generated POCO Classes

[Include code samples]

### Dependencies
- None (independent analysis)

### Related Files
- All `*.xml` files in repository
