RFC: thin Async Core ABI for PHP (zend_async_API) — mechanism-only coroutine API with a policy-free core
- scheduler_rfc.md — PHP RFC: Async Scheduler Hook API. The activation contract: how a scheduler registers and drives coroutines (policy vs. mechanism).
- SCHEDULER.md — the exact engine invocation points, for scheduler implementers.
- reactor.md — Reactor C Interface (discussion draft). A hypothetical
callback-first
io_*reactor API — poll, streaming IO, timers, filesystem, cross-thread triggers and DNS — and how it feeds the scheduler. Includes an io_uring sketch and a hazards analysis. Not an RFC.
