Reproducible Build Standard

Builds executed from the same source commit must produce bit-for-bit identical binary artifacts.

Reproducibility Invariants

• Pinned Environments: Compiler versions and container base images pinned by SHA256 digest.
• Normalized Timestamps: SOURCE_DATE_EPOCH used to ensure deterministic artifact timestamps.
• Strict Lockfiles: Lockfiles with cryptographic checksums enforced via --frozen-lockfile in CI.
