Report examples
Read img2det results as evidence, not a one-word verdict.
These public-safe controlled cases now link to reproducible inputs, exact hashes, and actual report JSON under the benchmark-manifest-v1 evidence bundle. Human maintainer sign-off remains pending and is disclosed separately from the generated evidence.
Camera metadata baseline
Controlled condition: Camera original: Deterministic project-owned RGB fixture saved once as JPEG quality 92 with synthetic test-camera EXIF.
Evidence to inspect: Camera identity EXIF is present
Interpretation: The image has camera-like supporting evidence and no strong AI provenance marker was detected.
Limit: Controlled fixture result only; it does not measure real-world prevalence or detector accuracy.
Camera metadata removed
Controlled condition: Camera original: Decoded camera-01 pixels and saved as JPEG quality 92 without EXIF.
Evidence to inspect: Camera identity EXIF is absent
Interpretation: The image has camera-like supporting evidence and no strong AI provenance marker was detected.
Limit: Controlled fixture result only; it does not measure real-world prevalence or detector accuracy.
Camera image recompressed once
Controlled condition: Camera original: Decoded camera-01 and recompressed once as JPEG quality 72 while retaining its test EXIF.
Evidence to inspect: Retained EXIF and JPEG quantization are detected
Interpretation: The image has camera-like supporting evidence and no strong AI provenance marker was detected.
Limit: Controlled fixture result only; it does not measure real-world prevalence or detector accuracy.
Camera image converted to WebP
Controlled condition: Camera original: Decoded camera-01 and converted to WebP quality 82 while retaining its test EXIF.
Evidence to inspect: Retained EXIF is detected after WebP conversion
Interpretation: The image has camera-like supporting evidence and no strong AI provenance marker was detected.
Limit: Controlled fixture result only; it does not measure real-world prevalence or detector accuracy.
AI provenance-marker baseline
Controlled condition: AI original export: Project-owned PNG with explicit OpenAI, trainedAlgorithmicMedia, and c2pa marker-only text chunks.
Evidence to inspect: OpenAI and trainedAlgorithmicMedia markers are detected
Interpretation: OpenAI/C2PA-style markers were found, but the C2PA signature has not been verified in this runtime.
Limit: Controlled fixture result only; it does not measure real-world prevalence or detector accuracy.
AI marker with metadata retained
Controlled condition: AI original export: Project-owned PNG with an XMP-shaped text chunk retaining OpenAI, trainedAlgorithmicMedia, and c2pa strings.
Evidence to inspect: OpenAI, XMP, and trainedAlgorithmicMedia markers are detected
Interpretation: OpenAI/C2PA-style markers were found, but the C2PA signature has not been verified in this runtime.
Limit: Controlled fixture result only; it does not measure real-world prevalence or detector accuracy.

Run the file first, then compare the report wording with the closest example. If the evidence is marker-only, missing, or platform-stripped, ask for the original file before making stronger claims.
