# Synthetic Plan-Run C — Minimal v1.7 Fixture

> **Plan quality: A** (95/100) — APPROVE
>
> Generated by trekplan v4.1.0 on 2026-05-10 — `plan_version: 1.7`
>
> Profile: `balanced`

## Context

Minimal synthetic fixture used by `tests/synthetic/plan-determinism.test.mjs`
forward-compat assertion: any v1.7 plan must validate cleanly under `--strict`
mode after the v4.1 schema additions (`profile_used`, `profile`, etc.).

## Implementation Plan

Each step targets one focused change. Three dummy steps satisfy the heading
+ manifest requirements without exercising real implementation.

### Step 1: Add config entry for verbose flag

- **Files:** `package.json`
- **Changes:** Add `verbose` boolean to config entry.
- **Reuses:** existing config-entry pattern.
- **Verify:** `grep -c "verbose" package.json` → expected: `1`
- **On failure:** revert
- **Checkpoint:** `git commit -m "feat(synth): add verbose config entry"`
- **Manifest:**
  ```yaml
  manifest:
    expected_paths:
      - package.json
    min_file_count: 1
    commit_message_pattern: "^feat\\(synth\\): add verbose"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
  ```

### Step 2: Define types for verbose mode

- **Files:** `types.ts`
- **Changes:** Export `VerboseMode` enum with `silent | normal | verbose`.
- **Reuses:** existing type-export pattern.
- **Verify:** `grep -c "VerboseMode" types.ts` → expected: `1`
- **On failure:** revert
- **Checkpoint:** `git commit -m "feat(synth): define VerboseMode enum"`
- **Manifest:**
  ```yaml
  manifest:
    expected_paths:
      - types.ts
    min_file_count: 1
    commit_message_pattern: "^feat\\(synth\\): define VerboseMode"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
  ```

### Step 3: Wire verbose flag into parseArgs

- **Files:** `cli.ts`
- **Changes:** Recognise `--verbose` flag in `parseArgs`, pass `VerboseMode` to logger.
- **Reuses:** parseArgs flag-recognition pattern.
- **Verify:** `grep -c "--verbose" cli.ts` → expected: `1`
- **On failure:** revert
- **Checkpoint:** `git commit -m "feat(synth): wire --verbose into parseArgs"`
- **Manifest:**
  ```yaml
  manifest:
    expected_paths:
      - cli.ts
    min_file_count: 1
    commit_message_pattern: "^feat\\(synth\\): wire --verbose"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
  ```

## Verification

- [ ] `node lib/validators/plan-validator.mjs --strict --json tests/synthetic/plan-run-C.md` → `valid: true`, no `PLAN_VERSION_MISMATCH` warning

## Estimated Scope

- **Files to modify:** 3
- **Files to create:** 0
- **Complexity:** low (synthetic fixture only)
