NOTE: diff-ref mode entry (code committed in the same
commit as this log); backfilled from the live dev
session transcript per the `/prompt-io` skill rules.

> `git log -1 -p --follow -- piker/service/_actor_runtime.py`

Generated: normalize each registry addr via
`tractor.discovery._addr.wrap_address()` before
`.unwrap()`-ing for the `accept_addrs` bind check —
entries may be raw `tuple`s when passed in from (test)
client code. Import-path precedent taken from
`piker/cli/__init__.py:336`.

> `git log -1 -p --follow -- piker/service/_registry.py`

Generated: `check_for_service()` ported to
`tractor.query_actor(name, regaddr=...)` (kwarg was
`arbiter_sockaddr=`), unpacking the new
`(sockaddr, portal)` yield, and passing the
now-required `open_registry(addrs=Registry.addrs)`.

Key diagnostic reasoning (verbatim from session):

- the "DID NOT RAISE ContextCancelled" failure: in this
  test the client actor IS pikerd (in-proc), and
  current `tractor` main absorbs a `ContextCancelled`
  whose canceller is your own actor — self-requested
  cancels now exit cleanly instead of raising; the
  'sigint' variant propagates a bare collapsed
  `KeyboardInterrupt` rather than a
  `BaseExceptionGroup`.
- the hard-coded `trio.fail_after(9)` startup budget is
  marginal — full stack boot (pikerd -> emsd ->
  brokerd.kraken -> paperboi + live kraken symbology
  fetch) occasionally exceeds 9s -> bumped to 19s.
- `RemoteActorError.type` -> `.boxed_type`;
  `Position.size` -> `.cumsize` (the paper engine
  populates `BrokerdPosition.size` from `pp.cumsize`).
- overlap survey (user-requested): all of the
  `repair_tests` branch commits are already in this
  stack's ancestry; this commit finishes that branch's
  port mission (its f4c4f1e2 fixed `conftest.py`'s
  `arbiter_sockaddr` usage; this fixes the remaining
  `test_services.py` + `check_for_service()` sites).
