Deats,
- use `proc.poll() is None` in `sig_prog()` to
distinguish "still running" from exit code 0;
drop stale `breakpoint()` from fallback kill
path (would hang CI).
- add missing `raise` on the `RuntimeError` in
`async_main()` when no tpt bind addrs given.
- clean up stale uid entries from the registrar
`_registry` when addr eviction empties the
addr list.
- update `discovery.__init__` docstring to match
the new eager `._multiaddr` import.
- fix `registar` -> `registrar` typo in teardown
report log msg.

New locality-aware addr preference for multihomed
actors: UDS > local TCP > remote TCP. Uses
`ipaddress` + `socket.getaddrinfo()` to detect
whether a `TCPAddress` is on the local host.
Deats,
- `_is_local_addr()` checks loopback or
same-host IPs via interface enumeration
- `prefer_addr()` classifies an addr list into
three tiers and picks the latest entry from
the highest-priority non-empty tier
- `query_actor()` and `wait_for_actor()` now
call `prefer_addr()` instead of grabbing
`addrs[-1]` or a single pre-selected addr
Also,
- `Registrar.find_actor()` returns full
`list[UnwrappedAddress]|None` so callers can
apply transport preference

Adjust all imports to match.

[claude-code-gh]: https://github.com/anthropics/claude-code
Replace `Registrar._registry: bidict[uid, addr]`
with `dict[uid, list[UnwrappedAddress]]` to
support actors binding on multiple transports
simultaneously (multi-homed).
Deats,
- `find_actor_addr()` returns first addr from
the uid's list
- `get_registry()` now returns per-uid addr
lists
- `find_actor_addrs()` uses `.extend()` to
collect all addrs for a given actor name
- `register_actor_addr()` appends to the uid's
list (dedup'd) and evicts stale entries where
a different uid claims the same addr
- `delete_actor_addr()` does a linear scan +
`.remove()` instead of `bidict.inverse.pop()`;
deletes the uid entry entirely when no addrs
remain

Re-export `parse_endpoints`, `parse_maddr`, and
`mk_maddr` in `discovery.__init__` so downstream
(piker) can import directly from the pkg ns.

[claude-code-gh]: https://github.com/anthropics/claude-code
Provide a service-table parsing API for downstream projects (like
`piker`) to declare per-actor transport bind addresses as a config map
of actor-name -> multiaddr strings (e.g. from a TOML `[network]`
section).
Deats,
- `EndpointsTable` type alias: input `dict[str, list[str|tuple]]`.
- `ParsedEndpoints` type alias: output `dict[str, list[Address]]`.
- `parse_endpoints()` iterates the table and delegates each entry to the
existing `tractor.discovery._discovery.wrap_address()` helper, which
handles maddr strings, raw `(host, port)` tuples, and pre-wrapped
`Address` objs.
- UDS maddrs use the multiaddr spec name `/unix/...` (not tractor's
internal `/uds/` proto_key)
Also add new tests,
- 7 new pure unit tests (no trio runtime): TCP-only, mixed tpts,
unwrapped tuples, mixed str+tuple, unsupported proto (`/udp/`),
empty table, empty actor list
- all 22 multiaddr tests pass rn.

Drop the `.lstrip('/')` on the unix protocol value
so the lib-prepended `/` restores the absolute-path
semantics that `mk_maddr()` strips when encoding.
Pass `Path` components (not `str`) to `UDSAddress`.
Also, update all UDS test params to use absolute
paths (`/tmp/tractor_test/...`, `/tmp/tractor_rt/...`)
matching real runtime sockpath behavior; tighten
`test_parse_maddr_uds` to assert exact `filedir`.

Strip leading `/` from `filepath` before building
the `/unix/{path}` multiaddr string; OW absolute
sockpaths like `/run/user/1000/tractor/foo.sock`
produce `/unix//run/..` which `py-multiaddr`
rejects as "empty protocol path".
Woops, missed this in the initial `mk_maddr()` impl
bc the unit tests only used relative `filedir` values
(which was even noted in a comment..). The bug only
surfaces when the `.maddr` property on `UDSTransport`
is hit during logging/repr with real runtime addrs.
Found-via: cross-suite `pytest tests/ipc/ tests/msg/`
where `tpt_proto='uds'` leaks into msg tests

Inverse of `mk_maddr()`: parse a multiaddr string like
`/ip4/127.0.0.1/tcp/1234` back into a tractor `Address`.
Deats,
- add `_maddr_to_tpt_proto` reverse mapping dict
- add `parse_maddr()` fn dispatching on protocol
combo: `[ip4|ip6, tcp]` -> `TCPAddress`,
`[unix]` -> `UDSAddress`
- strip leading `/` the multiaddr lib prepends to
unix protocol values for correct round-trip
- add `str` match case in `wrap_address()` for
`/`-prefixed multiaddr strings, broaden type hint
to `UnwrappedAddress|str`

Address Copilot review: the mapping table was
defined but never referenced. Now `mk_maddr()`
resolves `proto_key` -> maddr protocol name via
the table and rejects unknown keys upfront.
Also add missing `Path` import to the `multiaddr`
usage snippet.

Drop the NIH (notinventedhere) custom parser (`parse_maddr()`,
`iter_prot_layers()`, `prots`/`prot_params` tables) which was never
called anywhere in the codebase.
Replace with a thin `mk_maddr()` factory that wraps the upstream
`multiaddr.Multiaddr` type, dispatching on `Address.proto_key` to build
spec-compliant paths.
Deats,
- `'tcp'` addrs detect ipv4 vs ipv6 via stdlib
`ipaddress` (resolves existing TODO)
- `'uds'` addrs map to `/unix/{path}` per the
multiformats protocol registry (code 400)
- fix UDS `.maddr` to include full sockpath
(previously only used `filedir`, dropped filename)
- standardize protocol names: `ipv4`->`ip4`,
`uds`->`unix`
- `.maddr` properties now return `Multiaddr` objs
(`__str__()` gives the canonical path form so all
existing f-string/log consumers work unchanged)
- update `MsgTransport` protocol hint accordingly

Move the `Arbiter` class out of `runtime._runtime` into its
logical home at `discovery._registry` as `Registrar(Actor)`.
This completes the long-standing terminology migration from
"arbiter" to "registrar/registry" throughout the codebase.
Deats,
- add new `discovery/_registry.py` mod with `Registrar`
class + backward-compat `Arbiter = Registrar` alias.
- rename `Actor.is_arbiter` attr -> `.is_registrar`;
old attr now a `@property` with `DeprecationWarning`.
- `_root.py` imports `Registrar` directly for
root-actor instantiation.
- export `Registrar` + `Arbiter` from `tractor.__init__`.
- `_runtime.py` re-imports from `discovery._registry`
for backward compat.
Also,
- update all test files to use `.is_registrar`
(`test_local`, `test_rpc`, `test_spawning`,
`test_discovery`, `test_multi_program`).
- update "arbiter" -> "registrar" in comments/docstrings
across `_discovery.py`, `_server.py`, `_transport.py`,
`_testing/pytest.py`, and examples.
- drop resolved TODOs from `_runtime.py` and `_root.py`.

Restructure the flat `tractor/` top-level private mods
into (more nested) subpackages:
- `runtime/`: `_runtime`, `_portal`, `_rpc`, `_state`,
`_supervise`
- `spawn/`: `_spawn`, `_entry`, `_forkserver_override`,
`_mp_fixup_main`
- `discovery/`: `_addr`, `_discovery`, `_multiaddr`
Each subpkg `__init__.py` is kept lazy (no eager
imports) to avoid circular import issues.
Also,
- update all intra-pkg imports across ~35 mods to use
the new subpkg paths (e.g. `from .runtime._state`
instead of `from ._state`)
