Baseline and Boundary Prompt Sequence

Establish a reproducible baseline for this repository before implementing any feature.

First inspect the documented setup and propose the exact bounded commands needed to verify language and dependency versions, install or validate dependencies, prepare local data, run migrations, build, test, start, and perform a minimal health check. Identify commands that write files, alter data, contact external systems, or require credentials.

Wait for approval before running mutating setup steps. After approval, execute the checklist in order and record command, exit status, relevant counts, test results, local URL, runtime evidence, failures, and limitations. Do not repair a failure until the baseline report distinguishes an existing defect from an environment problem.
