Beyond "Trial and Error": Applying a Modified Waterfall SDLC to the Inbox Inferno Challenge

Hi everyone

:waving_hand:

I’m publishing only the diagrams here for now (high-level architecture, workflow/process flowchart, sequence, data flow diagrams, ERD, ingestion pipeline, decision logic, infrastructure/deployment, container topology, and error-handling/resilience).

I will share Doc No. 3 later.

Comments, questions, or requests for extra detail are very welcome — thanks for reading and for the great feedback so far.

:placard: Note: These diagrams are preliminary and may not be 100% accurate yet. I may publish improved versions later, but they are still very helpful for understanding the system architecture and workflow.
