Reconsidered after actually feeling the friction: this data is JSON over MQTT (not binary protobuf), only continuum-proxy ever parses it (raw vendor wire format, never crosses into TS), so none of protobuf's actual value (cross-language codegen, binary wire efficiency) applied here. Every gotcha hit while building this (field_attribute's oneof/variant path collision, needing .bambulab-scoped type_attribute calls, explicit #[serde(default)] per not-always-present field) came from forcing prost-build's codegen model onto a plain-JSON, Rust-only use case. Verified the replacement is strictly simpler, not just smaller: a hand-written struct's Option<T> field needs zero extra attributes to handle a missing JSON key (prost's generated String needed an explicit field_attribute call per field), and #[serde(flatten)] on a hand-written field has no ambiguity at all (prost-build's oneof/variant path collision doesn't exist without prost-build's codegen in the picture). The replacement lives in continuum-proxy: src/printer/bambu_commands/. continuum.v1 is unaffected — that schema is genuinely cross-language and proto still earns its keep there.
