## Phase Details

### Phase 1: cnc-abstraction ✅

**Goal:** Fix namespace, add all Cnc/ files to csproj, complete ICncMachine + IFanucMachine with 3-file support
**Completed:** 2026-05-13

**Delivered:**
- Namespace `Fanuc_integration.Cnc.*` → `FanucProgramManager.Cnc.*` (29 files)
- `IFocasDialect` extended: `UploadStart`/`DownloadStart` accept `short fileType`
- `IFanucMachine` interface: extends `ICncMachine` with tool offset + work zero R/W
- `CncManufacturer` enum: Fanuc, Heidenhain, Siemens
- All 29 `Cnc/**/*.cs` files added to csproj

### Phase 2: heidenhain ✅

**Goal:** Implement ICncMachine for Heidenhain TNC via LSV2 protocol
**Completed:** 2026-05-13

**Delivered:**
- `HeidenhainConnectionConfig` — IP, port 19000, credentials, timeout
- `Lsv2Client` — TCP framing, CRC-16/CCITT, login (SELECT+LOG_IN), ReceiveFile/SendFile
- `HeidenhainMachine : ICncMachine` — RunGuardedAsync pattern, state machine

### Phase 3: siemens ✅

**Goal:** Implement ICncMachine for Siemens Sinumerik via FTP
**Completed:** 2026-05-13

**Delivered:**
- `SiemensConnectionConfig` — IP, port 21, creds, program dir `/_N_MPF_DIR/`
- `SiemensFtpClient` — FtpWebRequest wrapper, ASCII mode, passive
- `SiemensMachine : ICncMachine`

**Bonus (post-apply):**
- `MitsubishiConnectionConfig` / `MitsubishiFtpClient` / `MitsubishiMachine : ICncMachine`
- `CncManufacturer.Mitsubishi` added to enum + factory + CLI

### Phase 4: program-wiring ✅

**Goal:** Wire all manufacturers into Program.cs + InputArgs
**Completed:** 2026-05-13

**Delivered:**
- `CncMachineFactory` — creates right `ICncMachine` from `InputArgs`
- `InputArgs` — added `manufacturer`, `username`, `password` fields
- `Program.cs` — full rewrite using `ICncMachine` factory; Fanuc 3-file via `IFanucMachine` cast

### Phase 5: nc-validator ✅

**Goal:** Per-manufacturer NC program validator runs inside WriteProgramAsync before upload
**Completed:** 2026-05-13

**Delivered:**
- `ValidationSeverity` / `ValidationError` / `ValidationResult` model types
- `INcProgramValidator` + `NcProgramValidator` with universal + per-manufacturer rules
- Validator injected into all 4 machine classes
- `NcProgramValidatorTests` — 30+ NUnit tests

## Next Milestone

**v0.2 License System** (proposed)
Status: Not started

Planned scope:
- Hardware fingerprint (CPU ID + disk serial)
- Encrypted license file (AES, offline)
- License generator tool (internal)
- Replace hardcoded key/IV
