# Phase 6 Plan 1: Rename Cleanup Summary

**FanucProgramManager → NcProgramManager across 62 .cs files, 3 project/solution files, test folder rename, FANUCMachine.cs deleted.**

## Performance

| Metric | Value |
|--------|-------|
| Duration | ~5 min |
| Started | 2026-05-17 |
| Completed | 2026-05-17 |
| Tasks | 3 completed |
| Files modified | 62 .cs + 3 project files + 1 folder rename + 1 file deleted |

## Acceptance Criteria Results

| Criterion | Status | Notes |
|-----------|--------|-------|
| AC-1: Namespace renamed everywhere | Pass | grep returns zero results across all .cs files |
| AC-2: Project/solution files updated | Pass | AssemblyName, RootNamespace, ProjectReference all updated; files renamed |
| AC-3: Dead code removed | Pass | FANUCMachine.cs deleted; Compile entry removed from csproj |

## Accomplishments

- All namespaces, using directives, AssemblyTitle, AssemblyProduct, InternalsVisibleTo updated in one sed pass
- Project and test folder physically renamed to match new name
- Zero FanucProgramManager strings remain in .cs, .csproj, or .sln

## Files Created/Modified

| File | Change | Purpose |
|------|--------|---------|
| All 62 `.cs` files | Modified | `FanucProgramManager` → `NcProgramManager` namespace/usings |
| `NcProgramManager.csproj` | Renamed + modified | AssemblyName + RootNamespace updated |
| `NcProgramManager.sln` | Renamed + modified | Project references updated |
| `NcProgramManager.Tests/NcProgramManager.Tests.csproj` | Renamed + modified | AssemblyName, RootNamespace, ProjectReference updated |
| `FANUCMachine.cs` | Deleted | Dead code — zero references outside itself |

## Decisions Made

| Decision | Rationale | Impact |
|----------|-----------|--------|
| Keep `FanucMachine`, `FanucProgram`, `IFanucMachine` names | These are manufacturer-specific identifiers, not project names | Future phases reference these names unchanged |

## Deviations from Plan

None — plan executed exactly as written.

## Issues Encountered

None.

## Next Phase Readiness

**Ready:**
- All code under `NcProgramManager` namespace
- Project builds under new name (pending Windows build verification)
- Clean foundation for license system phases

**Concerns:**
- Build not verifiable on Linux (fwlib32 Windows-only DLL) — same as before

**Blockers:** None
