The CCF Customer Journey
From Pattern Guessing to Proof-Based Mastery
CCF turns isolated coding practice into a deliberate path: learn the structure, investigate the evidence, derive the Operation, and prove the Answer Space.
Problem Space → Reasoning Operation → Answer Space → Proof

| Journey Stage | Student Mindset | CCF Focus | Case Files / Lessons | Simulator Experience | Outcome |
|---|---|---|---|---|---|
| Beginner | “I don't know where to start.” | Problem Space, Answer Space, Operation, Frame, Scanner, Recorder, Invariant, Proof | Public previews #001 Target Element through #006 Minimum Window | Guided decisions | Identify a Problem Space, Answer Space, and basic Operation. |
| Investigator | “I can follow the method.” | Recorder state, graph identity, and dynamic programming | Starter Plan: published guided Case Files #007 House Robber through #014 Invert Binary Tree | Structured prompts | Complete the published Starter Plan path. |
| Operator | “I can apply the method.” | Published Data Structures & Algorithms library | New investigations are added when their complete learning experiences are released. | Repeated operations | Apply CCF across growing DSA families. |
| Strategist | “I can choose the operation.” | Blind Investigation Mode and transfer drills | Classify Problem Spaces by required Operation | Faded guidance | Select a lawful Operation without a pattern label. |
| Master | “I can transfer CCF beyond DSA.” | Pro Plan | SQL, Git, .NET, system design, AI prompts, automation | Real-system reasoning | Use CCF in engineering systems. |
