LaserData SDK over Apache Iggy: typed streaming, operational and lakehouse query, materialization destinations, key-value state, copy-on-write forks, and an optional agent runtime with the Agent Data Exchange Protocol (AGDX).
// The provenance header dictionary lives in laser-wire (it is on-the-wire
// contract, shared with every port). Re-exported here so the historical
// `provenance::keys::*` paths keep resolving.
