build(deps): pin protobuf to 3.20.3 in fuzzer_runner for OSS-Fuzz compatibility#456
Conversation
…patibility Add uv constraint-dependencies to prevent protobuf from being updated beyond 3.20.3, which is required for compatibility with OSS-Fuzz infrastructure. This prevents dependabot from creating PRs like #453 that would break the fuzzer runner. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
constraint-dependenciesto pin protobuf at 3.20.3 in fuzzer_runnerContext
The fuzzer_runner depends on
clusterfuzzwhich transitively pulls inprotobuf. Dependabot was attempting to update protobuf in the lock file (see #453), but this would break compatibility with OSS-Fuzz which uses protobuf 3.20.3.The
constraint-dependenciesfeature in uv explicitly pins protobuf and documents why in the pyproject.toml.Test plan
