Case
- Goal
- Evaluate Cargo semver bare requirement caret defaulting, prerelease tuple isolation, zero-version breaking bounds, and build metadata equality HOW
- Packages
- semver 1.0.28
- Environment
- rust
- Created

Contract
- assert bare requirement 1.2.3 defaults to caret ^1.2.3 accepting 1.2.4 and 1.3.0 while rejecting 2.0.0
- assert ^0.2.3 rejects 0.3.0 and ^0.0.3 rejects 0.0.4 because zero-major releases treat minor/patch as breaking
- assert ~0.0.3 accepts 0.0.4 making tilde looser than caret for zero-major zero-minor ranges
- assert wildcard * matches all stable versions but rejects prereleases like 1.0.0-alpha.1
- assert >=1.2.3-alpha.1 accepts 1.2.3-alpha.2 and 1.2.4 but rejects 1.2.4-alpha.1 due to Cargo tuple isolation
- assert Rust Version struct Eq and Ord differentiate build metadata whereas VersionReq matches ignores it
- assert leading zeros are forbidden in numeric prerelease identifiers but allowed in build metadata
