Guide 06 · Output

Create one report for one audience.

VRAVEN deliberately writes one selected report per invocation. That keeps commands predictable and prevents stale output from being mistaken for current evidence.

Format	Best for
html	Interactive local review and sharing as one self-contained page.
pdf	Archival review and fixed-layout submission. Browser-based PDF support must be available.
json	Automation, reproducibility checks and downstream analysis.
