Scenario runs and benchmarks write a run directory under the configured output root.

​
Directory layout

The base layout for one run is: 
<output>/<run-id>/
├── env/
│   ├── device.json
│   └── runtime.json
├── screenshots/
├── sources/
├── summary.txt
├── summary.json
├── junit.xml
├── timeline.log
└── report.html

​
Report files

​
summary.txt

A compact text summary with:
  • run id
  • platform
  • device
  • run status
  • determinism signature
  • artifact count

​
summary.json

A canonical JSON serialization of the full run result. This is the most complete machine-readable report file.

​
junit.xml

A JUnit-style report built from step results. Important detail:
  • test cases correspond to scenario steps
  • failures in the JUnit output reflect step failures
  • assertion failures are not represented as separate JUnit test cases

​
timeline.log

A compact ordered list of step results. Each line contains:
  • sequence number
  • step id
  • command
  • status
  • duration in milliseconds

​
report.html

A minimal HTML summary page. Current contents are intentionally simple:
  • run id
  • final status
  • artifact count

​
Environment files

env/runtime.json contains:
  • seed
  • started timestamp
  • ended timestamp
env/device.json contains:
  • platform
  • device

​
Artifact materialization

Raw artifact paths from the run are copied into the report directory. Copy behavior:
  • screenshots are copied into screenshots/
  • non-PNG artifacts are copied into sources/
  • copied files are renamed with a zero-padded numeric prefix
Example: 
screenshots/001-app-opened.png
sources/002-counter-after-increment-ui.xml

​
Which operations create artifacts

OperationArtifact type
screenshotPNG image
sourceXML source dump
runFull report directory plus copied artifacts
benchmarkOne full report directory per iteration

​
Report helper behavior

visor also exposes a report helper that returns the expected report location format for a given output root. It does not parse or render existing reports. It only returns path guidance.
