ConstraintThe product problem
A Node.js utility centered on YouTube download and media-stream handling. The engineering challenge is to turn that scope into a legible system with explicit inputs, dependable workflow boundaries, and an outcome that can be inspected and maintained.
SystemThe architecture decision
The reviewed implementation routes media url / processing options through media acquisition & transformation, crosses media & transcription services where required, and produces media asset / transcript.
OutcomeThe operating result
New YTDL Core is included as documented engineering work. Its source structure, technology stack, and functional flow are presented here even though no verified public deployment is currently available.
