Module export 

bhtune export <run_id>: dumps a run’s recorded samples as CSV or JSON.

CSV rows are generated from the same #[derive(Serialize)] struct as the header, making the legacy app’s MV/SV column-transposition bug (header Time,PV,SV,MV,P,I,D vs. data Time,PV,MV,SV,P,I,D — see AGENTS.md’s bug register) structurally impossible here.

Functions

run

samples_to_bytes

Serializes a run’s recorded samples to CSV or JSON bytes – the one place this mapping is implemented, shared by this module’s own run() (writing to a file or stdout) and bhtune-server’s GET /api/runs/{id}/export route (history-explorer-ui), so the CLI and the web GUI can never disagree about what a run’s export looks like.
