Ownership gate

Gate 1: Ownership Verification

"If you can't explain it, you don't own it. And code you don't own will haunt you in interviews."

Purpose

This gate ensures the junior truly understands the code they've written. It's the only gate that can BLOCK task completion, because ownership is non-negotiable.

Gate Status

• BLOCKED — Junior cannot explain the code → Must review and understand before proceeding
• PASS — Junior demonstrates clear understanding

---

Gate Questions

Ask these questions in sequence. If the junior struggles significantly, mark as BLOCKED.

Question 1: Walk-Through

"Walk me through what this code does, step by step."

Looking for:

• Accurate description of the flow
• Understanding of data transformations
• Awareness of async operations
• Correct terminology

Red flags:

• "I'm not sure, I just copied this pattern"
• "The AI suggested this"
• Significant inaccuracies in description

Question 2: Why This Approach

"Why did you choose this approach? What alternatives did you consider?"

Looking for:

• Awareness of trade-offs
• Consideration of alternatives
• Reasoning about the decision
• Connection to requirements

Red flags:

• "It was the first thing that worked"
• "This is how it's done"
• No awareness of alternatives

Question 3: Change Scenario

"If the requirements changed to [specific scenario], what would you modify?"

Looking for:

• Understanding of which parts are flexible
• Awareness of dependencies
• Ability to reason about modifications
• Confidence in the architecture

Red flags:

• "I'd have to rewrite everything"
• Complete uncertainty about where to change
• Inability to identify the affected areas

Question 4: Edge Case

"What happens if [edge case specific to their code]?"

Looking for:

• Awareness of edge cases
• Understanding of failure modes
• Knowledge of error handling in the code

Red flags:

• "I didn't think about that"
• Complete surprise at the scenario
• No error handling for obvious cases

If BLOCKED

🛑 OWNERSHIP GATE: BLOCKED

I noticed some gaps in understanding this code. Before we proceed:

1. **Review these sections:** [specific lines/functions]
2. **Understand the flow:** Trace through with sample data
3. **Research if needed:** [specific concept to review]

This isn't about perfection — it's about ensuring YOU own this code.
Take 15-20 minutes to review, then let's try again.

Remember: In an interview, you'll need to explain this confidently.

If PASS

✅ OWNERSHIP GATE: PASSED

You clearly understand what you built and why. Nice work.

Key points you demonstrated:
- [Specific thing they explained well]
- [Understanding they showed]

Socratic Recovery

If the junior struggles, don't just block them. Guide them:

1. Point to the confusion: "Let's focus on this function. What does line X do?"
2. Break it down: "What data comes in? What comes out?"
3. Connect to concepts: "This is a [pattern]. Have you seen this before?"
4. Rebuild understanding: "Now, can you walk through it again?"

Only BLOCK if they still cannot explain after guided review.

Why This Gate Matters

Without Ownership	With Ownership
Copy-paste without understanding	Learn patterns for reuse
Can't debug when it breaks	Can reason about failures
Fails in interviews	Tells compelling stories
Dependent on AI	Independent problem solver

Interview Connection

"Every code review is interview prep."

After passing this gate, note:

• What concept did they explain well? (Future interview talking point)
• What initially confused them? (Area for deeper learning)
• What pattern did they use? (Add to their vocabulary)
