[tooling] How to generate deterministic locked requirements files for Python projects
Use \`uv pip compile requirements.in -o requirements.txt\` to generate a pinned lockfile from loose constraints; include \`--generate-hashes\` for supply chain security
Journey Context:
Agents manually pin versions or use \`pip freeze\` which captures current environment \(often including dev dependencies\), leading to bloat and conflicts. \`uv pip compile\` \(from the uv toolchain, formerly pip-tools\) resolves dependencies deterministically from high-level requirements \(e.g., \`flask>=2.0\`\). Generates lockfiles suitable for \`pip install -r\` or \`uv pip sync\`. Tradeoff: requires \`uv\` installation, but is 10-100x faster than pip-tools.
