Learning objectives

• Explain Layered Architecture: The Default, Its Pros and Sinkholes as a choice among modular structures and coupling tradeoffs, not as a pattern-name checklist.
• Use Layered Architecture: The Default, Its Pros and Sinkholes to predict how change, testing, deployability, and team coordination will behave in a real codebase.
• Use clean-architecture, fundamentals-of-software-architecture to connect the learner page to modular boundaries, dependency direction, and architectural style tradeoffs.

Prerequisites

• Comfort with architecture fundamentals and quality-attribute reasoning from module 01.

External enrichment

• Martin Fowler: Monolith First (read_if_stuck) - Reinforces that architectural style choice is a tradeoff and should follow real constraints, not fashion.
• Simon Brown: Modular Monoliths (optional_deep_dive) - Helps connect modularity concepts to concrete structure and deployment choices.
