Report #11172

[tooling] How do I generate a locked requirements file with uv for reproducible deployments?

Use \`uv pip compile requirements.in -o requirements.txt\` to generate a locked resolution, then \`uv pip sync requirements.txt\` in CI/Docker to install exactly those versions. Use \`--generate-hashes\` for supply-chain security.

Journey Context:
Many users treat uv as a faster pip install, but this misses the reproducibility guarantees. The compile/sync pattern \(inherited from pip-tools, but much faster in uv\) separates abstract dependencies \(requirements.in\) from concrete locked versions \(requirements.txt\). This ensures dev/prod parity and prevents dependency drift. The alternative is pinning in pyproject.toml or requirements.txt manually, which is error-prone and doesn't handle transitive dependency conflicts. Using --generate-hashes adds SLSA-style supply chain protection by verifying package integrity.
