requires:
  - phase: 15-01
    provides: NLog wired into all classes; _log field + _log.Error in Program.cs
provides:
  - All operator output through NLog (_log.Info)
  - Console shows plain text identical to before (${message} layout)
  - All output timestamped in log file

tech-stack:
  added: []
  patterns: ["All Console.Write/WriteLine replaced with _log.Info; operator output fully NLog-routed"]

key-files:
  modified: [nlog.config, Program.cs]

key-decisions:
  - "Multi-line Console.WriteLine block split into 7 individual _log.Info calls — one per field"
  - "Console.ReadLine() in VediErrore preserved — debug pause, not output"
  - "console rule uses levels='Info' not minlevel — Warn/Error to file only"

# Phase 15 Plan 02: Console → NLog Summary

**All 97 Console.Write/WriteLine calls in Program.cs replaced with `_log.Info`; nlog.config console target reconfigured to plain `${message}` layout, Info-only.**

## Performance

| Metric | Value |
|--------|-------|
| Duration | ~30min |
| Tasks | 2 completed |
| Files modified | 2 |

## Acceptance Criteria Results

| Criterion | Status | Notes |
|-----------|--------|-------|
| AC-1: Console output unchanged for operator | Pass | layout=`${message}`; no level/logger prefix; text identical |
| AC-2: All operator output recorded in log file | Pass | file rule minlevel="Debug" unchanged; Info calls go to file |
| AC-3: Warn/Error stay out of operator console | Pass | console rule `levels="Info"` (not minlevel) — Warn/Error file only |

## Accomplishments

- Program.cs: zero Console.Write/Console.WriteLine calls remain
- nlog.config: console target layout=`${message}`, rule `levels="Info"` (exactly Info only)
- Full operator session now timestamped in `logs/nc_program_manager.log`

## Files Created/Modified

| File | Change | Purpose |
|------|--------|---------|
| `nlog.config` | Modified | Console target: layout `${message}`, rule `levels="Info"` |
| `Program.cs` | Modified | 97 Console.* calls → _log.Info; 103 _log.Info total; 3 _log.Error unchanged |

## Decisions Made

| Decision | Rationale | Impact |
|----------|-----------|--------|
| Multi-line Console.WriteLine → 7 _log.Info calls | One call per field is cleaner; log file shows each field on its own timestamped line | _log.Info count 103 vs plan-predicted 98 |
| Console.ReadLine() preserved | Debug pause, not output — out of scope per plan constraints | grep Console. = 1, not 0 |

## Deviations from Plan

### Summary

| Type | Count | Impact |
|------|-------|--------|
| Auto-fixed | 0 | — |
| Scope additions | 0 | — |
| Count discrepancy | 1 | Immaterial |

### Detail

**_log.Info count: 103 vs plan-predicted 98**
- Plan expected: 97 former WriteLine + 1 merged pair = 98
- Actual: multi-line `Console.WriteLine("manufacturer: " + ... "\n" + ...)` was 1 call but split to 7 `_log.Info` calls (one per field)
- Impact: none; all output correct; count difference is additive not subtractive

**grep -c "Console\." = 1, not 0**
- Plan verification regex `Console\.` matches Console.ReadLine() which must stay (debug pause)
- Zero `Console.Write` / `Console.WriteLine` remain — plan intent fully met
- Plan's verify command was slightly too broad

## Issues Encountered

None.

## Next Phase Readiness

**Ready:**
- Phase 15 logging complete — both plans done
- All operator output through NLog with timestamps
- Warn/Error isolated to log file; console clean

**Concerns:**
- None

**Blockers:**
- None — Phase 15 complete; v0.5 milestone complete
