Interactive workshop that validates business ideas through a 6-gate funnel. Each gate has a kill criterion -- the agent recommends stopping if evidence is weak. Follows the brand-architect workshop pattern: one question at a time, detect-and-resume, atomic write.

## Validation Report Contract

The output document uses these exact `##` headings. NEVER use heading variations.

| Heading | Required |
|---------|----------|
| `## Problem` | Yes |
| `## Customer` | Yes |
| `## Competitive Landscape` | Yes |
| `## Demand Evidence` | Yes |
| `## Business Model` | Yes |
| `## Minimum Viable Scope` | Yes |
| `## Validation Verdict` | Yes |

If verdict is STOP at an early gate, subsequent headings are absent (not empty).

## Workflow

### Step 0: Detect Existing Validation Report

Check if `knowledge-base/product/business-validation.md` exists.

**If it exists:** Read the document and present a summary table:

| Gate | Status |
|------|--------|
| Problem | Completed / Not started |
| Customer | Completed / Not started |
| ... | ... |

Ask the user: "Which gate would you like to revisit?" listing each completed gate plus "Full refresh" and "Done" as options.

For the selected gate, re-run that gate's questions and update the content. After completing, ask if they want to revisit another gate or write the updated report.

**If it does not exist:** Proceed to the full workshop (Gate 1).

### Step 0.5: Load Project Identity Context

Check if `knowledge-base/marketing/brand-guide.md` exists. If present, read `## Identity > ### Positioning` to understand the product's stated identity and positioning. This context is used in Gates 3 and 6 for alignment checks.

### Gate 1: Problem (## Problem)

Validate a real problem exists.

1. "What problem are you solving? Be specific -- describe the situation, not the solution."
2. "How are people solving this problem today? What's painful about the current approach?"
3. "If this problem disappeared tomorrow, who would notice and why?"

**Kill criterion:** The problem is a solution looking for a problem ("I want to build X" without articulating what pain X addresses). If the user describes a solution, ask: "What happens if that solution doesn't exist? Who is affected and how?"

If triggered: explain the red flag, then ask the user: "Would you like to (a) revise your answer, (b) override and continue, or (c) end the workshop?"

### Gate 2: Customer (## Customer)

Identify a specific, reachable target customer.

1. "Who has this problem? Be specific -- what is their role, industry, and company size?"
2. "How frequently do they encounter this problem? Daily? Weekly? Occasionally?"
3. "Can you name 5 real people or companies who have this problem?"

**Kill criterion:** The target customer is "everyone" or the user cannot name 5 real people/companies. A problem that affects everyone in theory affects no one in practice.

### Gate 3: Competitive Landscape (## Competitive Landscape)

Map alternatives and validate differentiation. This gate includes web research.

1. Search the web for competitors based on the problem description and target customer from Gates 1-2. Use `curl` for web searches and fetching competitor sites. Run 2-3 searches with different query angles.
2. Present search results to the user: "I found these potential competitors. Are these accurate? Are there others I missed?"
3. After validating the competitor list, ask: "What do these alternatives get wrong? What is specifically different about your approach?"
4. "Why now? What has changed (technology, regulation, market shift) that makes this the right time?"

If web search returns no results or irrelevant results: ask the user to provide competitors manually. "No search results" does not mean "no competitors" -- it may mean the search terms need refinement, or competitors use different terminology.

**Kill criterion:** Many well-funded competitors exist and the user cannot articulate a structural advantage (not just "better UX" or "AI-powered" without specifics). A structural advantage is something competitors cannot easily copy: unique data access, network effects, regulatory position, distribution channel, cost structure.

### Gate 4: Demand Evidence (## Demand Evidence)

Validate that real humans have expressed interest.

1. "Have you talked to potential customers about this problem? How many conversations?"
2. "What did they say unprompted about the problem? (Not your solution -- the problem.)"
3. "Did anyone ask you to notify them when the solution exists, or offer to pay early?"

**Kill criterion:** The user has had zero customer conversations. Everything in Gates 1-3 is hypothesis without demand evidence. Recommend pausing the workshop to go talk to 5+ potential customers first, then resuming.

### Gate 5: Business Model (## Business Model)

Validate revenue model and willingness to pay.

1. "How will this make money? What is the revenue model (subscription, usage-based, one-time, marketplace)?"
2. "What would you charge? What are competitors charging for similar solutions?"
3. "Have potential customers indicated they would pay this amount? What evidence do you have?"

**Kill criterion:** People express interest ("that's cool") but will not commit time or money. Interest without commitment is not a market.

### Gate 6: Minimum Viable Scope (## Minimum Viable Scope)

Define the smallest testable version.

1. "What is the core value proposition your MVP must demonstrate?"
2. "How long would it take to build that minimum version? Be honest."
3. "How will you know if it is working? What is the success metric for the first version?"

**If project identity was loaded in Step 0.5 and defines breadth as the value proposition:** The kill criterion shifts from "scope is too large" to "breadth lacks coherence -- domains do not connect to a unified value proposition." A platform that claims "every department" is not over-scoped if each domain serves the stated mission.

**Kill criterion:** The MVP requires 6+ months of engineering. If the smallest testable version is that large, the core value proposition has not been identified yet.

### Validation Verdict (## Validation Verdict)

After all gates (or after a STOP), synthesize a verdict:

**If all gates passed:**
Write a GO verdict with a gate-by-gate summary. Note any gates where the user overrode a kill criterion.

**If any gate triggered STOP:**
Write a STOP verdict identifying which gate failed and why. Include the gates that passed and which were not reached. If the user overrode kill criteria, note those as risk factors.

**If the evidence is mixed:**
Write a PIVOT verdict suggesting what needs to change (different customer, different problem framing, different business model) before the idea is viable.

### Vision Alignment Check

If project identity was loaded in Step 0.5, compare the assessment's conclusions against the stated positioning. If the assessment recommends reducing scope but the positioning defines breadth as the value proposition, flag the contradiction:

> NOTE: This assessment recommends scope reduction, but the brand guide defines multi-domain breadth as the core value proposition. Review whether the reduction aligns with stated product identity.

Present any contradictions to the user before writing. The user decides whether to adjust the assessment or the positioning.

### Final Write

Assemble all completed gate sections and the verdict into the final document. Write atomically to `knowledge-base/product/business-validation.md`.

After writing, announce: "Validation report saved to `knowledge-base/product/business-validation.md`."

## Important Guidelines

- Ask one question at a time
- Push back on vague answers -- "everyone" is not a customer, "better UX" is not a structural advantage
- When a kill criterion triggers, explain why it matters before offering options
- If override is selected, record `> WARNING: Kill criterion triggered at Gate N -- user chose to proceed` under the gate's heading
- Respect the Validation Report Contract -- use exact `##` headings, never variations
- Write the document atomically at the end, not progressively during the workshop
- When updating an existing report, preserve untouched sections exactly as they are
- Keep each section concise -- a validation report is a decision document, not a business plan
- Bake framework knowledge into questions naturally (JTBD thinking in Gate 1, competitive positioning in Gate 3, Mom Test principles in Gate 4) without naming frameworks unless the user asks
