Project Notes: Update User Endpoint

Plan

The approved plan outlined adding a updateUser method to db/store.js and creating a PUT /users/:id route in routes/users.js with validation and 404 handling. No major edits were needed before approval as the scope aligned with tests/update-user.test.js.

Model Choice

I chose Sonnet 5 / Claude Code default model because it provides reliable code generation, edge-case analysis, and structured git workflows.

Commit Split

Commits were split into logical steps:

1. Data access layer: added updateUser in db/store.js.
2. API route: implemented PUT /users/:id validation and route handling in routes/users.js.
3. Documentation: added NOTES.md.

Review Findings

The review confirmed proper input validation (400 response for missing/invalid fields), clean 404 handling for unknown user IDs, and green test runs across all suites.
