Inventory [SUPPLIED SOURCE MATERIAL] for a teaching resource. Identify the original creator and source link when supplied, the materials actually accessible, and what you inspected. Separate caption, slides, transcript, video, and official documentation.
Extract the outcome, inputs, visible actions, decisions, prompts, intermediate results, and stated limits. Preserve exact original prompts and quotes. Do not invent a transcript, screenshot, timestamp, setting, or skipped step.
Return a source map with evidence locations and gaps. Classify proposed clarifications as RECOMMENDED ADDITIONS and missing factual details as UNRESOLVED. Recommend whether the material supports a full tutorial, a limited explanation, or inspiration only. Explain why.
