Part 2: Services and Contracts

Add PostgreSQL, fast checks, and a precise agent-readable feature contract.

Three chapters · approximately 3–5 focused hours, plus downloads and cloud setup. Stop after each verification gate. Paid model calls are optional until Part 3; cloud capacity and KVM are needed for the full capstone.

Chapter	Deliverable
04 · Real Services, Repeatable Checks	Start PostgreSQL through devenv and test a transaction without leaving persistent test data.
05 · Fast Feedback and Automatic Shells	Use targeted tasks for fast feedback and configure direnv with an explicit trust boundary.
06 · Specs, Plans, and Agent Memory	Define a feature before prompting and create a reviewed, failing acceptance test before the agent changes the implementation.

The next part consumes the evidence from this one. Do not advance on an assumed pass.
