 |---|---|---|---|
 | Fibers + I/O reactor | [KEP-0001](https://github.com/kaappi/keps/blob/main/keps/0001-event-loop-reactor.md) | **Final** — shipped | `(cond-expand (kaappi-fibers ...))`, `(cond-expand (kaappi-reactor ...))` |
 | SRFI-18 OS threads | — (R7RS-small doesn't cover threads; SRFI-18 predates this project) | Shipped | `(cond-expand (kaappi-threads ...))`, or `(cond-expand ((library (srfi 18)) ...))` |
-| Cross-thread channels | [KEP-0002](https://github.com/kaappi/keps/blob/main/keps/0002-cross-thread-channels.md) | **Accepted** — core mechanism shipped; the two wakeup-path correctness issues open at 0.14.x ([#1487](https://github.com/kaappi/kaappi/issues/1487), [#1489](https://github.com/kaappi/kaappi/issues/1489)) were fixed in v0.15.0 | Not yet exposed via `cond-expand`: [KEP-0004](https://github.com/kaappi/keps/blob/main/keps/0004-discoverable-deviations.md) gates a `kaappi-shared-channels` identifier on the wakeup path shipping with its review findings resolved — the fixes have shipped, the identifier has not yet; check `kaappi features` on your build |

 | Shared flat numeric buffers | [KEP-0003](https://github.com/kaappi/keps/blob/main/keps/0003-shared-flat-numeric-data.md) | **Draft** — unimplemented, gated behind KEP-0002 usage data | None — doesn't exist yet |
