# Step 1b: Resume Workflow

## STEP GOAL

Resume an interrupted workflow by loading the existing output document, displaying progress, and routing to the next incomplete step.

## MANDATORY EXECUTION RULES

- 📖 Read the entire step file before acting
- ✅ Speak in `{communication_language}`

---

## EXECUTION PROTOCOLS:

- 🎯 Follow the MANDATORY SEQUENCE exactly
- 📖 Load the next step only when instructed

## CONTEXT BOUNDARIES:

- Available context: Output document with progress frontmatter
- Focus: Load progress and route to next step
- Limits: Do not re-execute completed steps
- Dependencies: Output document must exist from a previous run

## MANDATORY SEQUENCE

**CRITICAL:** Follow this sequence exactly.

### 1. Load Output Document

Read `{outputFile}` and parse YAML frontmatter for:

- `stepsCompleted` — array of completed step names
- `lastStep` — last completed step name
- `lastSaved` — timestamp of last save

**If `{outputFile}` does not exist**, display:

"⚠️ **No previous progress found.** There is no output document to resume from. Please use **[C] Create** to start a fresh workflow run."

**THEN:** Halt. Do not proceed.

---

### 2. Display Progress Dashboard

Display progress with ✅/⬜ indicators:

1. ✅/⬜ Preflight & Context (step-01-preflight-and-context)
2. ✅/⬜ Generation Mode (step-02-generation-mode)
3. ✅/⬜ Test Strategy (step-03-test-strategy)
4. ✅/⬜ Generate Tests + Aggregate (step-04c-aggregate)
5. ✅/⬜ Validate & Complete (step-05-validate-and-complete)

---

### 3. Route to Next Step

Based on `lastStep`, load the next incomplete step:

- `'step-01-preflight-and-context'` → load `./step-02-generation-mode.md`
- `'step-02-generation-mode'` → load `./step-03-test-strategy.md`
- `'step-03-test-strategy'` → load `./step-04-generate-tests.md`
- `'step-04c-aggregate'` → load `./step-05-validate-and-complete.md`
- `'step-05-validate-and-complete'` → **Workflow already complete.** Display: "✅ **All steps completed.** Use **[V] Validate** to review outputs or **[E] Edit** to make revisions." Then halt.

**If `lastStep` does not match any value above**, display: "⚠️ **Unknown progress state** (`lastStep`: {lastStep}). Please use **[C] Create** to start fresh." Then halt.

**Otherwise**, load the identified step file, read completely, and execute.

The existing content in `{outputFile}` provides context from previously completed steps.

## 🚨 SYSTEM SUCCESS/FAILURE METRICS

### ✅ SUCCESS:

- Output document loaded and parsed correctly
- Progress dashboard displayed accurately
- Routed to correct next step

### ❌ SYSTEM FAILURE:

- Not loading output document
- Incorrect progress display
- Routing to wrong step

**Master Rule:** Resume MUST route to the exact next incomplete step. Never re-execute completed steps.
