Wed Riley's Transition-speed presets, install.sh, Preferences and bench sweep into the macOS 27 engine instead of keeping two engines. Ramps now build on the same event creators as instant (strafe_create_ramp_event, both profiles) and run through the observe-and-confirm pipeline, so speed and profile compose. The fire-and-forget ramp poster and waitForPendingSwitch have no callers left and are gone; the CLI waits on the real completion instead. Also in this merge: single-transient-read tolerance in the poll loop, a one-second overlay grace that never disables interception over Mission Control's close animation, and a strafe mc-probe diagnostic (AX notifications plus Dock layer census) after overlay detection proved silent on 27.
Mashing swipes through Mission Control's close animation could pause trackpad interception after a single failed request: the failure breaker fired on the first unexpectedChange, and overlay detection is silent on some systems so no grace applied. Now a changing anomaly polls on until the deadline, only a stable wrong destination fails fast, and pausing takes three delivery failures in a row (any success resets). A failure within a second of an overlay is still neither counted nor reported.
mc-probe showed Dock's AX overlay notifications never arrive on 27, while Mission Control presents exactly one Dock window at layer 20 (closed desktop shows none). The snapshot heuristic required a layer-18 window, so it never fired and synthetic switches went into Mission Control. A lone layer-20 Dock window is now an overlay signal, and the engine consults the snapshot at request admission in addition to the AX flag. Interceptor behavior is unchanged: Began already passed through on the snapshot.

Thank you Oz! I saw this after making an update for mac 27 earlier. Is there anything particular here that you feel is worth still pulling in compared to the latest update? |

Adopt the reviewed Mission Control detection check from PR #2, with a macOS 27 availability guard, regression tests, contributor acknowledgment, and the scoped contribution-security review. Preserve the individual commits so Ozair retains authorship of the adapted fix.

Hey Riley! Been using Strafe since you open sourced it :)
macOS 27 completely broke it (synthetic swipes get swallowed, nothing moves), so I dug in and got it working again on 27.0 arm64. Hotkeys, swipes, both edges, Mission Control passthrough all verified live.
What's in here:
STRAFE_EVENT_PROFILEto forcelegacy/macos27. Pre-27 defaults are untouched.strafe mc-probediagnoses this live).Two apologies: I know you love the line count, so I'm sorry about all the tests. Totally fine if you want them trimmed or dropped. And I couldn't check anything pre-27 here, so a 26 sanity look would be great.
bench/still drives the synchronous poster.Happy to split this up or rework anything. Thanks for strafe!
