Abstract C++20 provides symmetric transfer ([P0913R1](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0913r1.html)[1]) - a mechanism where `await_suspend` returns a `coroutine_handle<>` and the compiler resumes the designated coroutine as a tail call. Coroutine chains execute in constant stack space. `std::execution`

Abstract `std::execution::task` ([P3552R3](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2025/p3552r3.html)[1]) had open issues identified by national ballot comments, LWG issues, and published papers. Croydon resolved several. This paper classifies each issue by whether it can be resolved after C++26 ships or whether shipping forecloses the fix, and notes which classified issues were addressed at Cr

Abstract The Environment parameter in `std::execution::task` makes cross-library coroutine interoperability structurally impossible without knowing every query by name.

Abstract The sender composition algebra does not apply to compound I/O results without losing data, and the construction that preserves all data produces code identical to the coroutine version.

Abstract Both coroutines and senders destroy compound data at an abstraction floor - the difference is that the sender floor sits below the composition algebra, and the coroutine floor is opt-in.

Abstract A single class template bridges sender-based code into coroutine-native I/O with inline operation state, correct stop propagation, and automatic dispatch-back.

Abstract Coroutine-native awaitables can be wrapped as senders, but compound I/O results must be reduced to an error code before crossing the bridge.

Abstract Of the four deficiencies that [P1525R0](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1525r0.pdf)[1] identified in `execute(F&&)`, three do not arise under the original framing of the callable as a continuation, and the fourth addresses a different question.

Abstract The committee set aside the Networking TS in 2021. The process had no mechanism to verify that the analysis examined every applicable framing, and no mechanism to revisit the outcome against evidence.
