Proposed resolution:

This wording is relative to N5014.

1. Modify [exec.inline.scheduler] as indicated:

   -3- Let `sndr` be an expression of type inline-sender, let `rcvr` be an expression such that receiver_of<decltype((rcvr)), CS> is `true` where `CS` is completion_signatures<set_value_t()>, then:

   • (3.1) — the expression `connect(sndr, rcvr)` has type inline-state<remove_cvref_t<decltype((rcvr))>> and is potentially-throwing if and only if `((void)sndr, auto(rcvr))` is potentially-throwing, and
   • (3.2) — the expression get_completion_scheduler<set_value_t>(get_env(sndr)) has type `inline_scheduler` and is potentially-throwing if and only if `get_env(sndr)` is potentially-throwing.

[exec.inline.scheduler] bullet (3.2) reads:

• (3.2) — the expression get_completion_scheduler<set_value_t>(get_env(sndr)) has type `inline_scheduler` and is potentially-throwing if and only if `get_env(sndr)` is potentially-throwing.

`get_env(sndr)` is never potentially-throwing because it mandates that `sndr.get_env()` cannot throw, see [exec.get.env].

also, get_completion_scheduler<set_*_t>(attrs) mandates that attrs.query(get_completion_scheduler<set_*_t>) cannot throw.
