Popover animation assignments such as popover.animates = flag must still go through a Motion gate. This preserves the broad assignment guard and exempts only the explicit false literal, including a trailing statement or closing block. Variables, comparisons, and false || flag remain rejected.

Follow-up to the nonblocking P3 review finding on #27136. Leo’s requirement: “You click, you get a response, period. Everything. Every single f***ing instance.” This guard can land independently; #27136 must preserve it when integrating the updated base.

Validation at exact source 9834c685f6e5383a0015b3ce32eadd21220dac55:

• Managed Linux red/green run 40931154661 passed. Replaying the preceding guard fails the new multiline fixture as intended; the repaired guard passes the complete shell suite, shell syntax and diff checks.
• Independent Codex gpt-6-astra HIGH/FAST review of the full own diff: SHIP at this exact head. The reviewer also ran the regression suite and the guard against the real CmuxNext package; both passed.

The false exemption checks the next significant Swift line, so false followed by || flag, a type check or member access remains rejected. This also closes the multiline hole identified during the follow-up review.

No capture: this changes the source guard and executable shell fixtures only.
