Struct ImageMetadataLimits 

pub struct ImageMetadataLimits {
    pub max_decompressed_bytes: u64,
    pub max_xml_depth: u32,
    pub max_xml_events: u64,
    pub max_boxes: u64,
    pub max_rows: u64,
    pub max_output_bytes: u64,
}

The image-metadata parser ceilings, held as rules data beside the records ceilings so a deployment raises them in a visible versioned bump. The parent reads them from the registry and passes them into the jailed worker, which enforces them and fails a source over any ceiling with a stable image-metadata-* reason. The metadata worker runs behind the shared platform-default jail, so these are the parser-surface ceilings only, not the wall-clock and address-space envelope the runner already imposes.

Fields

max_decompressed_bytes: u64

Inflated-size ceiling for any single compressed text block, the png zTXt and compressed iTXt streams above all. Checked incrementally during inflation so a decompression bomb is stopped before it lands.

max_xml_depth: u32

Nesting-depth ceiling for an xmp parse.

max_xml_events: u64

Event-count ceiling for an xmp parse.

max_boxes: u64

Box-count ceiling for an iso base media file format carrier.

max_rows: u64

Ceiling on emitted metadata rows across all surfaces.

max_output_bytes: u64

Ceiling on the rendered value bytes, under the runner response cap.
