Repository Possession Prompt Sequence

Explain exactly how a new authorized engineer would prepare and start this repository locally without changing it.

Identify required language and tool versions, dependency manifests and lockfiles, environment variables by name but never secret value, databases, migrations, seed data, build steps, startup commands, ports, health checks, and shutdown procedure. Cite the files supporting each instruction.

Flag undocumented assumptions, platform-specific paths, globally installed tools, missing lockfiles, and steps that could contact production or incur cost. Do not install dependencies or start services yet. End with a proposed bounded startup checklist.
