Versioned JSON envelope types shared between the public fallow CLI and the closed-source fallow-cov production-coverage sidecar.
Fallow Runtime, the paid runtime intelligence layer for fallow, is a two-binary architecture. The open-source fallow CLI handles static analysis and IO. A separate closed-source sidecar (fallow-cov) does V8-to-Istanbul normalization, three-state tracking, and combined scoring. Both sides marshal data through JSON on stdin/stdout. This crate is the single source of truth for that envelope so the two repositories cannot drift.
The protocol_version field is a full semver string. Consumers MUST reject mismatched majors and SHOULD forward-accept unknown fields and unknown enum variants (mapped to Unknown sentinel values).
