## 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`
