# Build Delta Evidence Kit 0.1.0

The package turns one successful Unity Player build into the minimum `bdg-summary-v0.1` evidence file used by the local Build Delta Guard comparator.

## Processing boundary

All processing occurs synchronously inside the Unity Editor after the build. The package writes one local UTF-8 JSON file and performs no network request.

## Evidence boundary

Unity version, build target, total output bytes, build duration, explicit contract labels, and registered package versions are included. Optional payload metrics and all project content are excluded. Because optional evidence is missing, the current comparator returns `REVIEW` even when the two core signals remain within budget.

## CI contract

Set the nine required `XESOFT_BDG_*` environment variables documented in the package README. Accepted and candidate jobs must use identical values for every contract label; only the revision label should differ.

## Output

Default directory: `Library/XeSoft/BuildDelta`

Optional override: `XESOFT_BDG_OUTPUT_DIR`

The exporter never reads or includes `BuildSummary.outputPath`.
