createEnvelope
fun createEnvelope(eventId: String, sessionId: String, sessionStartEpochMillis: Long, seq: Long?, globalSeq: Long?, sdk: String, eventTimestamp: String, schemaVersion: String? = null): Envelope
Builds an Envelope with caller-chosen field values, bypassing the stamper.
Exists only so autograph-test can offer testEnvelope(...) across the module boundary that internal does not cross. Use that instead: this signature carries no stability guarantee and gains a parameter whenever Envelope gains a property.
