…e stale A click whose handler opens alert/confirm/prompt froze jevAct: the press response, the probe read and settle all block on a dialog, so the act sat until the daemon's per-call timeout. jevAct now races the act against a per-tab dialog waiter fed by Page.javascriptDialogOpening; if the dialog wins, the press happened, so it returns ok and the next observe reports the dialog. Transport failures from actionablePoint are rethrown instead of being reported as a stale element. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…end no input
A dialog opened by the page before jev_act's first mutating command now
returns stale ("a dialog opened before the action") instead of ok, since
nothing happened. When a dialog wins the race after the press, the act is
marked abandoned so that, once the dialog is answered and the frozen
command resumes, it sends no selectAll, insertText or settle against
whatever is focused by then.

Part 2 of 3 for
reins do(stacked on #41; #43 builds on this).Why
Jev needs two things from the page, and both have to be fast:
What
jev_observe: a page snapshot ported from browser-use/jev-ultrafast (MIT). It returns:Nodes are cached page-side in a
Symbol.for("reins.jev")map. Password and hidden values are never included, and a browser test asserts it with a real value in a password field.jev_act: click, type, select, scroll or wait on a cached node. It reuses the existing actionability checks (actionPoint/actionablePointnow accept a node and a timeout;pressAtwas extracted fromcdpClick).Dialogs: tracked via
Page.javascriptDialogOpening/Closed.jev_actraces its work against a dialog opening, so a click that opensconfirm()returns right away instead of hanging.Tiers: both methods need tier
fullinMETHOD_TIERS.Testing
pointer.browser.test.ts, headless Chrome): a Jev fixture page covering the leak test (#pw holding "hunter2", hidden "secret"), a confirm-dialog click, and forwarding of CDP events.🤖 Generated with Claude Code
