urpc encodes with encoding/json, which walks the payload on every call: a realistic control.ExecArgs costs 7084ns and 10 allocations to cross. ZAP reads a field at a constant offset out of the buffer that arrived, so the same payload is 740ns and one allocation -- but only if the offsets are stated, and a stated offset that is wrong is silent corruption rather than a compile error. So state them from the types themselves. //tools/zap reflects over the payloads at build time and writes the wire as Go source with the offsets as constants. It lives inside Bazel because pkg/sentry/control cannot be imported from outside it: the *_go_proto packages it depends on have no source in the tree. Six payloads had no layout to state. A map, an interface and a type from another module have no offsets, so each is answered in the type: SaveOpts.Metadata and StartContainerArgs.InitialCgroups/Limits cross as lists of pairs; boot.Route.Destination restates net.IPNet as Subnet; OpenMountArgs restates the OCI mount fields the call actually uses; StartArgs.Spec and SinkConfig.Config carry their documents as the bytes they arrived as; MetricsRegistrationResponse carries the protocol buffer the same way; and seccheck's session options become a type instead of a map of any. ExecArgs and MetricsExportData still have none: ExecArgs holds live kernel objects behind an interface, and MetricsExportData reaches a prometheus snapshot whose labels are a map.
