Resolve #474 with a new `tests/trionics/test_taskc.py` (9 tests) covering the `trio.Nursery.start()` wrapper landed in PR #464, incl. the `modden.runtime.progman.open_wks()` use case dug out as a minimal repro. Deats, - the lossy `RuntimeError('child exited without calling task_status.started()')` only fires when the child absorbs its ambient cancel pre-`.started()` (graceful-teardown pattern); a well-behaved child surfaces `Cancelled` direct from `.start()` on `trio` 0.29 - verified empirically 1st. - `test_sibling_err_not_masked_by_startup_rte`: the `modden` case; ONLY the root-cause sibling `ValueError` escapes the nursery with the wrapper vs. bare-`.start()`'s lossy riding-along startup-RTE noise. - `test_pure_oob_cancel_not_morphed_to_rte`: plain ancestor `cs.cancel()` exits clean vs. bare's eg-wrapped RTE. - `test_genuine_startup_rte_still_raised`: sans cancellation the protocol-bug RTE re-raises same as bare. - `test_childs_own_rte_never_demoted_to_cancel`: exact-msg + `isinstance`-guard regression cover; a child's own `RuntimeError('never got started!')`/`RuntimeError(1234)` never demotes to a `Cancelled`. - `test_started_value_and_args_passthru`: positional args, `name=` and `.started()`-value forwarding. Also, - `use_start_or_cancel=False` params pin upstream `trio`'s current lossy behaviour as wart-documentation: a break on a `trio` upgrade likely means new upstream porcelain and the wrapper deserves a re-audit. - verified 0 flakes over 50 hammer runs + 2 impl mutations each caught by exactly the targeted tests.
