Content plan

Learners can split a core that's outgrown one head, or one context window.

Outcome

Learners can split a core that’s outgrown one head, or one context window.

Planned coverage

  • What a module is.
  • Modular monolith vs microservice, with the modular monolith as the default.
  • Integration through events and APIs.
  • Sync vs async integration.
  • Contract testing.

Agent payoff

A module is an agent-task-sized unit with its own context window. Integration contracts let parallel agents work without colliding.

Seeds

  • Module = task unit.
  • Integration contract = parallelization rule.
