🔴 Lockfile ignored and unknown flag fails the build
The Docker build runs uv pip install --locked --no-cache ., but uv pip install never reads uv.lock, so dependencies are re-resolved from pyproject.toml and reproducibility is not gained. --locked is also not a valid uv pip install option, so uv rejects it and the build fails.
Prompt for agents
The Dockerfile line `RUN pip install --no-cache-dir uv && uv pip install --locked --no-cache .` does not achieve the intended reproducible build. Two problems: (1) `uv pip install` (uv's pip-compatible interface) does not consume the project lockfile uv.lock at all — uv.lock is only used by uv's project commands such as `uv sync`, `uv run`, and `uv export`. So installing `.` re-resolves dependencies from pyproject.toml and the lockfile has no effect. (2) `--locked` is not a recognized option of `uv pip install` (it is a project-command flag), which will cause uv to error out and fail the Docker build. To actually install the pinned dependency tree from uv.lock, consider exporting the lock to a requirements file and installing that, e.g. `uv export --locked --no-dev --format requirements-txt -o requirements.txt` then `uv pip install --system -r requirements.txt`, followed by installing the local package without dependencies (`uv pip install --system --no-deps .`); or restructure to use `uv sync --locked` with the project environment. Verify the exact uv subcommands/flags against the uv version being installed.

This PR addresses the supply-chain pinning recommendation from issue #28 by adding a uv.lock file for the dma-api service and updating the Dockerfile to use it for reproducible builds.
Changes
Why
The issue #28 mentioned: "an optional lockfile (
uv lockexport) for the Docker build would make self-hosted builds reproducible."Without a lockfile, resolves dependencies at build time, which can pull different versions of transitive dependencies across builds. The uv.lock file ensures every build gets exactly the same dependency tree.
Verification
The Docker build should now produce identical images for the same source commit, regardless of when/where it's built.
Closes #28 (supply-chain pinning part).
