Parametrize `test_loglevel_propagated_to_subactor`
across `'debug'`, `'cancel'`, `'critical'` levels
(was hardcoded to just `'critical'`) and move it
above the parent-main tests for logical grouping.

Drop hand-copied `_fixup_main_from_name()` and `_fixup_main_from_path()`
in favor of direct re-exports from `multiprocessing.spawn`. Simplify
`_mp_figure_out_main()` to call stdlib's `get_preparation_data()`
instead of reimplementing `__main__` module inspection inline.
Also,
- drop `ORIGINAL_DIR` global and `os`, `sys`, `platform`, `types`,
`runpy` imports.
- pop `authkey` from prep data (unserializable and unneeded by our spawn
path).
- update mod docstring to reflect delegation.

Replace the subproc-based test harness with inline
`tractor.open_nursery()` calls that directly check
`actor._parent_main_data` instead of comparing
`__main__.__name__` across a process boundary
(which is a no-op under pytest bc the parent
`__main__` is `pytest.__main__`).
Deats,
- delete `tests/spawn_test_support/` pkg (3 files)
- add `check_parent_main_inheritance()` helper fn
that asserts on `_parent_main_data` emptiness
- rewrite both `run_in_actor` and `start_actor`
parent-main tests as inline async fns
- drop `tmp_path` fixture and unused imports

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
`settings.local.json` and widen `py313` → `py*`
so non-3.13 setups aren't blocked.

The `functools` rewrite forwarded all `kwargs`
through `_main(**kwargs)` to `wrapped(**kwargs)`
unchanged — the Windows `start_method` default
could leak to test fns that don't declare it.
The pre-wrapt code guarded against this with
named wrapper params.
Extract runtime settings (`reg_addr`, `loglevel`,
`debug_mode`, `start_method`) as closure locals
in `wrapper`; `_main` uses them directly for
`open_root_actor()` while `kwargs` passes to
`wrapped()` unmodified.

Realized a bit late that (pretty sure) i already tried this using
`wrapt` idea and waay back and found the same "issue" XD
The `wrapt.decorator` transparently proxies `__code__` from the async
test fn, fooling `pytest`'s coroutine detection into skipping wrapped
tests as "unhandled coroutines". `functools.wraps` preserves the sig for
fixture injection via `__wrapped__` without leaking the async nature.
So i let `claude` rework the latest code to go back to using the old
stdlib wrapping again..
Deats,
- `functools.partial` replaces `wrapt.PartialCallableObjectProxy`.
- wrapper takes plain `**kwargs`; runtime settings extracted via
`kwargs.get()` in `_main()`.
- `iscoroutinefunction()` guard moved before wrapper definition.
- drop all `*args` passing (fixture kwargs only).

Deats,
- drop unused `import tractor` (F401)
- fix `_Cache.locks` annotation to `trio.StrictFIFOLock`
- fix typos: "mabye-value", "Acquir lock"
- add `resources.pop()` cleanup in the caller if
`service_tn.start()` fails — prevents a
permanent `_Cache.resources` leak on
`__aenter__` failure (note: Copilot's suggested
outer `try/finally` in `run_ctx` would
re-introduce the atomicity gap)
- add `user_registered` flag so `users -= 1` only
runs when the task actually incremented
- move lock pop into the `users <= 0` teardown
block so the last exiting user always cleans up,
regardless of who created the lock; drop
now-dead `lock_registered` var
Also,
- swap `fid` for `ctx_key` in debug log msgs

Reverts the `_Cache.run_ctx` change from 93aa39db which
moved `resources.pop(ctx_key)` to an outer `finally`
*after* the acm's `__aexit__()`. That introduced an
atomicity gap: `values` was already popped in the inner
finally but `resources` survived through the acm teardown
checkpoints. A re-entering task that creates a fresh lock
(the old one having been popped by the exiting caller)
could then acquire immediately and find stale `resources`
(for which now we raise a `RuntimeError('Caching resources ALREADY
exist?!')`).
Deats,
- the orig 93aa39db rationale was a preemptive guard
against acm `__aexit__()` code accessing `_Cache`
mid-teardown, but no `@acm` in `tractor` (or `piker`) ever
does that; the scenario never materialized.
- by popping both `values` AND `resources` atomically
(no checkpoint between them) in the inner finally,
the re-entry race window is closed: either the new
task sees both entries (cache hit) or neither
(clean cache miss).
- `test_moc_reentry_during_teardown` now passes
without `xfail`! (:party:)

Documents the diagnostic session tracing why
per-`ctx_key` locking alone doesn't close the

The per-`ctx_key` locking fix in f086222d intended to resolve the

pass. TLDR, it doesn't Bp
Also add `collapse_eg()` to the test's ctx-manager stack so that when
run with `pytest <...> --tpdb` we'll actually `pdb`-REPL the RTE when it
hits (previously an assert-error).

(Hopefully!) solving a long-run bug with the `brokerd.kraken` backend in
`piker`..
- Track `_Cache.users` per `ctx_key` via a `defaultdict[..., int]`
instead of a single global counter; fix premature teardown when
multiple ctx keys are active simultaneously.
- Key `_Cache.locks` on `ctx_key` (not bare `fid`) so different kwarg
sets for the same `acm_func` get independent `StrictFIFOLock`s.
- Add `_UnresolvedCtx` sentinel class to replace bare `None` check;
avoid false-positive teardown when a wrapped acm legitimately yields
`None`.
- Swap resource-exists `assert` for detailed `RuntimeError`.
Also,
- fix "whih" typo.

Reproduce the piker `open_cached_client('kraken')` scenario: identical
`ctx_key` callers share one cached resource, and a new task re-enters
during `__aexit__` — hitting `assert not resources.get()` bc `values`
was popped but `resources` wasn't yet.
Deats,
- `test_moc_reentry_during_teardown` uses an `in_aexit` event to
deterministically land in the teardown window.
- marked `xfail(raises=AssertionError)` against unpatched code (fix in
`9e49eddd` or wtv lands on the `maybe_open_ctx_locking` or thereafter
patch branch).

tracking correctly tears down resources independently - exercises the

`resource_id` for per-key testing in the above suite.

Namely with multiple pre-sleep `delay`-parametrizations before either,
- parent-scope cancel-calling (as originally) or,
- depending on the new `cancel_by_cs: bool` suite parameter, optionally
just immediately exiting from (the newly named)
`maybe_cancel_outer_cs()` a checkpoint.
In the latter case we ensure we **don't** inf sleep to avoid leaking
those tasks into the `Actor._service_tn` (though we should really have
a better soln for this)..
Deats,
- make `cs` args optional and adjust internal logic to match.
- add some notes around various edge cases and issues with using the
actor-service-tn as the scope by default.
- Use `Type[BaseException]` (not bare `BaseException`)
for all err-type references: `get_err_type()` return,
`._src_type`, `boxed_type` in `unpack_error()`.
- Add `|None` where types can be unresolvable
(`get_err_type()`, `.boxed_type` property).
- Add `._src_type_resolved` flag to prevent repeated
lookups and guard against `._ipc_msg is None`.
- Fix `recevier` and `exeptions` typos.

Drop the `xfail` test and instead add a new one that ensures the
`tractor._exceptions` fixes enable graceful relay of
remote-but-unregistered error types via the unboxing of just the
`rae.src_type_str/boxed_type_str` content. The test also ensures
a warning is included with remote error content indicating the user
should register their error type for effective cross-actor re-raising.
Deats,
- add `test_unregistered_err_still_relayed`: verify the
`RemoteActorError` IS raised with `.boxed_type`
as `None` but `.src_type_str`, `.boxed_type_str`,
and `.tb_str` all preserved from the IPC msg.
- drop `test_unregistered_boxed_type_resolution_xfail`

an effectively entirely repeated test just with an inverse assert
as it's last line..

Make `RemoteActorError` resilient to unresolved
custom error types so that errors from remote actors
always relay back to the caller - even when the user
hasn't called `reg_err_types()` to register the exc type.
Deats,
- `.src_type`: log warning + return `None` instead
of raising `TypeError` which was crashing the
entire `_deliver_msg()` -> `pformat()` chain
before the error could be relayed.
- `.boxed_type_str`: fallback to `_ipc_msg.boxed_type_str`
when the type obj can't be resolved so the type *name* is always
available.
- `unwrap_src_err()`: fallback to `RuntimeError` preserving
original type name + traceback.

`None` telling the user to call `reg_err_types()`.
