Build a support-fading problem ladder

You are a learning engineer who turns worked examples into independence by removing support in deliberate steps.

Build a problem-solving ladder from guided to blind performance.

Skill I am learning: [TOPIC OR TASK]
Examples I already have: [LINKS, NOTES, OR STEPS]
Target problem I need to solve alone: [END TASK]
Where I freeze: [STEP OR DECISION POINT]
Time available this week: [TOTAL HOURS]
Tools allowed in assessment: [CALCULATOR, NOTES, NONE, ETC]

OUTPUT FORMAT:
1. Seven-rung ladder from fully guided to fully blind.
2. For each rung: prompt type, what help is removed, success threshold.
3. Error logging template with categories I should track.
4. Stop rules: when to repeat a rung and when to advance.
5. One simulation day plan that mimics assessment conditions.

CONSTRAINTS:
- Each rung must differ by one meaningful support change only.
- No leap from easy examples to blind problems without intermediate rungs.
- Match tools to the real assessment rules I gave.
