50 - Certification-Grade Completion Protocol (Objective Mastery Standard)¶

This protocol defines the final standard for claiming mastery from this plan.

Completion requirements¶

You must pass all five: 1. Baseline doc chain completion (01 through 35). 2. Elite extension completion (36 through 45). 3. Universal learner layer completion (46 through 49). 4. Project evidence completion (level-0 through level-10 plus elite track). 5. Assessment completion (written, practical, oral defense).

Final evidence package¶

Portfolio links and summaries.
Capstone outputs and runbooks.
Test and quality gate records.
Architecture decision records.
Incident and remediation logs.

Detailed Scoring Rubrics by Level¶

## Summary
One paragraph: what this project does and why it exists.

## How to Run
Step-by-step instructions. Include dependencies.

## Design Decisions

- Passing: [N]
- Coverage: [X%] (if measured)

## Quality Checks
- [ ] ruff check passes
- [ ] black formatting applied

Capstone Submission Template¶

For level capstones and the elite track:

# [Capstone Title] — Level [X] Capstone

## Problem Statement
What real-world problem does this solve?

## Architecture
Describe the system design. Include a diagram if applicable.

### Components

## Operational Characteristics
- How does it handle failure?
- How would it scale to 10x load?
- What monitoring is in place?

## Test Strategy

- What is NOT tested and why

## Deployment
How to deploy this in a production-like environment.

## Retrospective
- What went well
- What was harder than expected
- What you would do differently

Peer Review Guidelines¶

Who Reviews¶

Levels 0–5: Self-review using the rubric above, or a study partner
Levels 6–8: Review by a peer who has completed the same level
Levels 9–10 and Elite: Review by a peer who has completed the curriculum, or a professional developer

Peer Review Process¶

Reviewer receives: the project repository (or fork link) and the submission template
Reviewer checks (30–60 minutes):
Clone the repo and run python -m pytest tests/
Run ruff check .
Read the code (focus on readability, not style preferences)
Read the submission template (are the design decisions genuine?)
Run the project and test 2–3 scenarios manually
Reviewer writes feedback using this template:

## Peer Review — [Project Name]

**Reviewer:** [Name/Handle]
**Date:** [Date]

### Rubric Scores
| Category | Score | Notes |
|----------|-------|-------|
| [Category] | [X/Y] | [Brief note] |

### Strengths
- [What the project does well]

### Areas for Improvement
- [Specific, actionable feedback]

### Questions for the Author
- [Things the reviewer wants the author to explain]

### Verdict
- [ ] Pass
- [ ] Pass with minor revisions (list them)
- [ ] Resubmit (explain what needs to change)

Review Ethics¶

Review the code, not the person
Be specific: "This function is 80 lines — consider splitting the validation into a helper" is better than "Code is too long"
Acknowledge what works before noting what does not
If you are unsure whether something is wrong, ask a question instead of making a statement

Defense / Presentation Format¶

When a Defense Is Required¶

Oral defense is required for: - Level 9–10 capstones - Elite track projects - Final certification claim

Defense is optional but recommended for: - Level 6–8 capstones - Expansion module completion

Defense Structure (30 Minutes)¶

Phase	Duration	Content
Presentation	10 min	Walk through the project: problem, design, implementation, results
Live demo	5 min	Show the project running. Demonstrate a normal flow and an error flow
Q&A	10 min	Examiner asks questions about design decisions, tradeoffs, alternatives
Code walkthrough	5 min	Examiner selects a section of code. Explain it line by line

Common Defense Questions¶

"Why did you choose this data structure / algorithm / pattern?"
"What happens if [input X] is provided?" (edge case probing)
"How would you scale this to handle 100x the current load?"
"What is the most fragile part of this system?"
"If you had two more weeks, what would you add or change?"
"Walk me through how you debugged [specific issue]."
"What does this test verify, and what does it NOT verify?"

Defense Scoring¶

Criterion	Weight	Excellent	Adequate	Insufficient
Clarity	25%	Explains concepts clearly without jargon	Understandable with some prompting	Cannot articulate design
Depth	25%	Understands internals, tradeoffs, alternatives	Surface-level understanding	Cannot go beyond "it works"
Honesty	25%	Acknowledges limitations and unknowns	Mostly honest, occasionally deflects	Claims perfection or avoids questions
Adaptability	25%	Thinks through new scenarios on the spot	Handles some curveballs	Cannot reason about changes

Pass threshold: "Adequate" or better in all four criteria.

Pass/fail rubric¶

Pass when all are true: 1. All required outputs are reproducible. 2. Quality gates pass without manual exception. 3. Tradeoff reasoning is clear and defensible. 4. Failure handling is tested and documented. 5. Remediation loops are closed with evidence.

Fail when any are true: 1. Hidden assumptions block reproducibility. 2. Test coverage is cosmetic. 3. Critical security or reliability controls are missing. 4. Oral defense cannot justify design decisions.
