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.

[claude-code-gh]: https://github.com/anthropics/claude-code
The prior approach eagerly reused `_parent_chan` when
parent IS the registrar, but that channel may still
carry ctx/stream teardown protocol traffic —
concurrent `unregister_actor` RPC causes protocol
conflicts. Now try a fresh `get_registry()` conn
first; only fall back to the parent channel on
`OSError` (listener already closed/unlinked).
Deats,
- fresh `get_registry()` is the primary path for
all addrs regardless of `parent_is_reg`
- `OSError` handler checks `parent_is_reg` +
`rent_chan.connected()` before fallback
- fallback catches `OSError` and
`trio.ClosedResourceError` separately
- drop unused `reg_addr: Address` annotation

A backlog of 1 caused `ECONNREFUSED` when multiple

`get_random()` can produce the same UDS filename for a given
pid+actor-state, so the "disjoint addrs" premise doesn't always hold.
Gate the `len(bound) >= 2` assertion on whether the registry and bind
addrs actually differ via `expect_disjoint`.
Also,
- drop unused `partial` import
(this commit msg was generated in some part by [`claude-code`][claude-code-gh])
[claude-code-gh]: https://github.com/anthropics/claude-code
When the parent actor IS the registrar, reuse the existing parent
channel for `unregister_actor` RPC instead of opening a new connection
via `get_registry()`. This avoids failures when the registrar's listener
socket is already closed during teardown (e.g. UDS transport unlinks the
socket file rapidly).
Deats,
- detect `parent_is_reg` by comparing `_parent_chan.raddr` against
`reg_addrs` and if matched, create a `Portal(rent_chan)` directly
instead of `async with get_registry()`.
- rename `failed` -> `failed_unreg` for clarity.

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

[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

[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.

Add 9 test variants (6 fns) covering all three
`tpt_bind_addrs` code paths in `open_root_actor()`:
- registrar w/ explicit bind (eq, subset, disjoint)
- non-registrar w/ explicit bind (same/diff
bindspace) using `daemon` fixture
- non-registrar default random bind (baseline)
- maddr string input parsing
- registrar merge produces union
- `open_nursery()` forwards `tpt_bind_addrs`
Fix type-mixing bug at `_root.py:446` where the
registrar merge path did `set(Address + tuple)`,
preventing dedup and causing double-bind `OSError`.
Wrap `uw_reg_addrs` before the set union so both
sides are `Address` objs.
Also,
- add prompt-io output log for this session
- stage original prompt input for tracking

[claude-code-gh]: https://github.com/anthropics/claude-code
Allow callers to explicitly declare transport
bind addrs instead of always auto-generating
random ones from ponged registrar addresses.
Deats,
- new `tpt_bind_addrs` kwarg wraps each input
addr via `wrap_address()` at init time.
- non-registrar path only auto-generates random
bind addrs when `tpt_bind_addrs` is empty.
- registrar path merges user-provided bind addrs
with `uw_reg_addrs` via `set()` union.
- drop the deprecated `arbiter_addr` param and
its `DeprecationWarning` shim entirely.
Also,
- expand `registry_addrs` type annotation to
`Address|UnwrappedAddress`.
- replace bare `assert accept_addrs` in
`async_main()` with a descriptive
`RuntimeError` msg.

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.

- add `parse_maddr()` fn dispatching on protocol

`[unix]` -> `UDSAddress`
- strip leading `/` the multiaddr lib prepends to

multiaddr parser rejects double-slash from abs paths
- `test_mk_maddr_unsupported_proto_key`: `ValueError`

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)

Move the subprocess probe into dedicated spawn test support files so the inheritance tests cover the real __main__ replay path without monkeypatching or inline script strings.
Clean up mutable defaults, give parent-main bootstrap data a named type, and add direct start_actor coverage so the opt-out change is clearer to review.
Use `inherit_parent_main` across the actor APIs and helper to better describe the behavior, and restore the reviewer note at child bootstrap where the inherited `__main__` data is copied from `SpawnSpec`.
Keep actor-owned parent-main capture and let `_mp_figure_out_main()` decide whether to return `__main__` bootstrap data, avoiding the extra SpawnSpec plumbing while preserving the per-actor flag.
Keep trio child bootstrap data in the spawn handshake instead of stashing it on Actor state so the replay opt-out stays explicit and avoids stale-looking runtime fields.
Let actor callers skip replaying the parent __main__ during child startup so downstream integrations can avoid inheriting incompatible bootstrap state without changing the default spawn behavior.
Expand `run-tests` skill `allowed-tools` to cover
the documented pre-flight workflow: `git rev-parse`
for worktree detection, `python --version`, and
`UV_PROJECT_ENVIRONMENT=py* uv sync` for venv
setup. Also dedup `gh api`/`gh pr` entries in
