The 8 `examples/debugging/` scripts driven by the pexpect'd
`test_debugger.py` REPL-flows (#477 removal),
- blocking one-shots (`subactor_error`, `subactor_breakpoint`,
`shielded_pause`): straight `to_actor.run(fn, an=an)` — the
boxed error/`BdbQuit` raises in the root's task.
- `multi_subactors`: introduces the "collect all errors" pattern
— each one-shot catches + stashes its `RemoteActorError` (vs
raising) so no child's crash cancels its siblings before
they've had their own REPL sessions, then a
`BaseExceptionGroup` of the lot raises at the end; preserves
the legacy teardown-reap REPL flow exactly (28/28 debugger
suite unchanged).
- `multi_nested_subactors_error_up_through_nurseries` +
`root_cancelled_but_child_is_in_tty_lock`: recursive
`spawn_until` levels each block on their one-shot child; the
parallel spawner-trees run as bg task-nursery one-shots where
the first tree's error cancels the other.
- `multi_subactor_root_errors` +
`root_timeout_while_child_crashed`: `start_actor()` + bg
`Portal.run()` tasks so the root's own error/timeout races the
already-crashed children, same as before.
- `sync_bp`: TODO-comment x-ref update only.
`test_debugger.py`: the nested-nurseries test's final-output
patterns update to the new relay shape — the LAST-released leaf
REPL's error chain wins each level's relay-vs-cancel race and
relays as a `collapse_eg()`-annotated collapsed chain, while the
sibling tree is cancelled + absorbed. (The legacy teardown-reap
grouped BOTH the `name_error` and bp-quit chains — explaining
the previously-mysterious "extra" `src_uid`/`relay_uid` patterns
noted in the old TODO.)
Gate: `tests/devx/test_debugger.py` = 28 passed, 6 skipped —
identical to the pre-migration baseline.
