Prompt

Same session-initiating brokerd-split instruction (see 20260610T170859Z_75cefe10_prompt_io.md). Proximate driver: the approved plan’s per-stage test gates could not run AT ALL — the branch base was broken vs. tractor git main (AttributeError: 'tuple' object has no attribute 'unwrap' at pikerd boot, stale arbiter_sockaddr/.type/.size API refs). The agent fixed forward autonomously to (re)establish the gate baseline, continuing the repair_tests branch lineage (verified already merged in ancestry via git cherry during a user-requested branch-overlap survey).

Response summary

Port the service layer + test suites to current tractor APIs: addr-type normalization in open_pikerd(), query_actor()/wait_for_actor() kwarg renames, modern self-cancel absorption semantics in the cancel-method test harness, exc/position attr renames, a paper-EMS startup-budget bump and a syntax fix in .deribit.api.

Files changed

• piker/service/_actor_runtime.py — wrap_address() normalize before .unwrap() in open_pikerd()
• piker/service/_registry.py — check_for_service() -> query_actor(regaddr=) + 2-tuple yield + open_registry(addrs=)
• piker/brokers/deribit/api.py — missing comma in tractor.trionics import tuple
• tests/test_services.py — registry_addr= kwarg, raddr unwraps, cancel-semantics harness rewrite, fail_after 9 -> 19s
• tests/test_ems.py — .boxed_type, pp.cumsize
