ConstraintThe product problem
An OAuth client utility that authenticates against the Guru API, refreshes expiring access tokens, and persists token state for service integrations. 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 input / action through domain & workflow logic, crosses external apis & platform services where required, and produces actionable result / automated outcome.
OutcomeThe operating result
API Call 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.
