SecureQRScanner

class SecureQRScanner(headerPrefixes: List<String> = listOf( "mDLQR:v2?", "mDLQR%3Av2?" ), assemblyTimeoutMs: Long, maxSessionAgeMs: Long, trustedTypeMetadataRegistries: List<String> = emptyList(), metadataResolver: SecureQRPayloadMetadataResolver = SecureQRPayloadMetadataResolver())

Thread-safe streaming QR assembler for SecureQR v2 frames.

Accumulates frames by session id (id=...).
Assembles once all frames 0..m-1 are present.
Strips last-frame padding (p=...).
Decodes v2 transport payload -> SD-JWT combined presentation.
Evicts old sessions (maxSessionAgeMs).

If you still want "soft assemble after timeout", set assemblyTimeoutMs> 0.
