spec:AST-094 FR20: a watcher registers only passive listeners, but the host gave every tracked finger's target a cancelable touchend. The host now counts, per target, the fingers a participant could claim (a recognizer that claims touches, or a press consumer): touchend is cancelable only while that count is above zero and passive otherwise, swapped like touchmove. The new test (a watcher's touch gets passive touchmove, touchend and touchcancel; a tap's touchend stays cancelable) fails on the previous head.
…ond route around ./internal/* Lab's per-module tsconfig paths (core's motion, gestures and touchPresentation) and the Sandbox/docsite resolver that served them opened a route around architecture:react-component-runtime INV13's ./internal/* subpath exports. Nothing in Lab imports those paths here; they're dropped, and the import guard now fails on any Lab import core doesn't export and on any Lab tsconfig alias for core.

… detaches The deferred unmount demotes the detached node, and demote asks for a fresh will-change read; the detached node now gets none, so no timer outlives the element (architecture:react-component-runtime INV5). Co-authored-by: Christopher Chedeau <vjeux@users.noreply.github.com>

…ine opacity The case that detaches a node mid-dip and attaches it again checked, 25 ms in, that the dip had written its low opacity inline. With the presented start, a curve's inline value is the one on screen as it starts and its end is written when it retires, so 25 ms into the fade out the node holds the fade's starting opacity while the model is already partway down. That case now checks what this guarantees: the call owns the opacity inline and the dip is under way; its assertions after the second attach are unchanged. A dip that starts from a dimmed opacity still leaves that low value on the node while the move waits to land, so a new case detaches such a node mid-dip and attaches it again: the move has landed and the node is visible. It fails (0.3 instead of 1) when the pending unmount does not land the waiting move on the node just detached, so that landing stays covered.
…style holds Whatever the inline style holds while the curve runs (the end, or, once the start-value write of meta#8340 is in, the start), iOS WebKit's rect and hit tests stay where the animation started: the note now says only what holds either way.
…t stream Ports cixzhang's meta#8072 action-group press (d2c3c78) onto this pull request's shared input stream, with no change to what it does. Its per-press listeners were registered straight on the document and the window with capture constants this layer no longer has, so the merged host failed to compile, and its window click listener would have doubled the input stream's click subscriber (two onClick calls per click once the host installs, and a listener its guard never removed). The press now subscribes its pointer's moves and lift and the window's own blur through subscribeInput for as long as it is held. It subscribes to click only while the host is not installed, drops that subscription after the lift's task, and an installing host takes it over, so a click is heard once. Her two host tests read the press's listeners on the window, where the stream registers them; a new case counts onClick per click before and after the host installs mid-press, and fails against each of three mutants (no takeover, no drop, no subscription).
…uard At this layer the host has no click listener of its own: the click guard (utils/clickGuard.ts) hears every click through one listener per window. cixzhang's meta#8072 action-group press, ported onto the input stream below, still disarmed the host's swallower and subscribed the host's onClick, so the merged host failed to compile. The press now disarms the click guard when it begins and subscribes no click: what it does is unchanged. The click-count case becomes: a group press adds no click listener of its own, before or after the host installs mid-press. GestureHost.test.ts resets the click guard after each case, so a guard one case armed no longer keeps its pointerdown subscription into the next (it hid the coarse host's pointerdown listener from a later case).
… that finger until it lifts (spec:AST-094 FR14) A recognition that claimed its touches and was then cancelled gave them back to the browser unless another recognition owned them, so a finger resting there could pinch-zoom the page. A gesture that cancels itself on a finger's move, a long press dragged past its tolerance after it began, gave back a finger that was dragging: the host stopped cancelling its moves and the page scrolled the rest of the drag, a hand change FR14 forbids and UIKit never makes (its scroll view never takes a touch another recognizer had). A cancel during a finger's move now keeps that finger claimed until it lifts; a resting finger is given back as before, and a waiting recognition that fails still gives its claim back. The new arena case fails on the previous code: the dragging finger reads unclaimed right after the cancel.
… scroller under it is at the edge spec:AST-094 FR19 and DEC-18 (proposed in meta#8628): a scrollEdge pan may cancel its touch's moves from the first one, only while every scroller under the finger sits at its edge and the finger moves away from it, and only the moves the browser would rubber-band; it still begins at FR17's 10 px. The first case reads the first 2 px move cancelled at the edge and fails on this head; the others keep what must not change: room to scroll leaves every move to the browser, a first move toward the content too, a pan without scrollEdge cancels nothing before it begins, and a touch the browser took for a scroll stays the browser's when the list reaches its edge.
… cancelled at the edge spec:AST-094 FR19 and DEC-18 (proposed in meta#8628). The sheet's scroll-edge pan at the top of its content: every touchmove the page sees is cancelled, the first one included. WebKit sends that first move at 2 px, before the sheet's 10 px begin, and it reaches the page uncancelled on this head; Chromium sends none inside its own 15 px slop, so there it proves only that nothing scrolls.
…e away from an edge spec:AST-094 FR19 and DEC-18 (proposed in meta#8628). GestureRecognizer gains keepsTouch(touchId), false by default and reached by the host through recognizerInternals: whether it holds that finger before it begins. A scrollEdge pan does while it is possible, the touch is a finger the browser has not taken, its travel so far goes the pan's own way, and no scroller under the finger can scroll for it (the probe its begin already reads), so only moves the browser would rubber-band are held, never a real scroll. The host's blocking touchmove check cancels a move a participant holds, as it does a claimed one; the arena already holds that move when the check runs, since the host feeds it from its window-capture subscriber first. The pan still begins at 10 px; a mouse or a pen is never held. The README says so.
…straight, (7, 7) and (8, 8), and the screen-edge band The FR18–FR22 verification row's real-touch states, in the gesture browser spec on a bare page: - a finger moved 9 px straight or (7, 7) over a scroll view keeps its tap and scrolls nothing; one moved 10 px or (8, 8) is a tap or a scroll, never both; a tap never cancels a touchmove; - a screen-edge pan on a strip as wide as its band, landing 40 px from the edge, has not claimed at 14 px of travel and claims at 15; - a touch landing 41 px from the edge never begins the edge pan, and the horizontal scroll it starts is not blocked. The bare fixture exposes the tap and screen-edge pan recognizers.
…edge-zone strip decides at UIKit's 15 px The host's arena environment had no viewSize, so under the real host a screen-edge pan never saw its edge zone while a touch was down and decided at 10 px, while its attach-time touch-action (read through the default environment) had already claimed the axis (spec:AST-094 FR18).

…fter layout rounding Lane 0's real-host browser spec found a strip authored at the 40.2 px edge region lays out at 40.203 px (layout snaps to 1/64 px), so the strict comparison read it as off the zone and the pan decided at 10 px instead of UIKit's 15 (spec:AST-094 FR18). The zone takes half a pixel of tolerance: the rounded strip is the zone, a view a pixel wider still is not. Failing-first test at 40.203 px: it claims pan-x and decides at 15.

…er and for the two stops the input stream fixes - A still finger with sub-pixel jitter over a scroll view keeps its tap and scrolls nothing (spec:AST-094 FR18–FR22). - A tap is still recognized under an app's window-capture stopPropagation, and under a document-capture stopImmediatePropagation registered before core's: the recognizers hear touches on the window's capture phase. Chromium and WebKit pass.
…s once Where nothing that claims is attached, the host's touchend listener is passive and cannot cancel the engine's own click after a retargeted tap clicks what is drawn. The shared click guard swallows that late click whatever is attached; this case pins it, as asked on meta#8293.
meta#8360 now carries the review fixes of the foundation it holds. The two conflicts are this pull request's own files: - GestureHost.ts: meta#8360 counts the attachments that ask for an action group; here the fine-pointer group listener and the per-event recognizer set are gone (every pointer is served, FR43), so the merge keeps the count and drops those two. - GestureHost.test.ts: both sides added the same assertion to the second-finger case; the merge keeps this side's comment. meta#8360's action-group lifetime case counts a group's own pointerdown under a fine pointer, which this pull request replaces with one passive pointerdown on any element that uses a gesture (its own idle-listener case), so the merge leaves it out.
… attached, in this host's terms meta#8360's action-group lifetime case pins that an element stays a group while any attachment asks and stops with the last. Here every element that uses a gesture is served as a group under a fine pointer, so the same invariant reads as the element's one passive pointerdown: with two gestures attached, detaching either keeps it, and detaching the last removes it. It passes on this head.

Approval waits on an engineering owner's decision about one spec sentence, and the branch still needs splitting from the stack it depends on. This head adds to spec:AST-094 FR41 that “a mouse or pen drag that a recognizer claims suppresses text selection for that drag only”, which main does not state and which FR41's unchanged verification row still fails; an engineering owner approves it, with that row amended, by commenting /approve-spec c793f217e0f7eaf457fdd6d6108df8aa38ae4949 on this pull request, or rejects it, and the author may record that decision as an engineering owner. Separately, the branch merges all of #8665 (about 28,000 changed lines) beside the five-file modifier-key change, so please land #8665 first and update this branch from main, which also takes the FR41 sentence out of this diff; the modifier-key change itself reads cleanly.

This sentence is a new requirement for a mouse and a pen, and it waits on an engineering owner's decision. It follows FR41's own “otherwise keeps its released behavior (spec:AST-017 FR59; DEC-9)”, and FR41's verification row further down still fails “a change to native selection elsewhere or to mouse, keyboard, or assistive-technology selection”, so if it is approved, that row needs amending in the same change; spec:AST-017 FR59 also asks for fine-pointer evidence before and after.
…esture host's subscriptions The gesture host subscribes no click: the one cancelling click subscriber is the click guard's, added at a window's first arm and kept. The release note, the stream's header and the gestures README listed click with the host's touchend and contextmenu; they now name the guard's own.
… lift and the browser's menu, keeps a kept press's finger, and goes when the page hides From the review of this pull request, three cases fail on its head: - an armed press installed the page listeners without the claiming ones, so a claimed finger's touchend stayed passive and the browser's menu opened during a claimed long press (spec:AST-094 FR21); - a kept press got its blocking touchmove during an armed press, but its moves were cancelled only where the primary pointer is coarse, so a held stepper on a touchscreen laptop lost its finger (FR11, DEC-21); - a page hidden mid-press cancelled the press but kept the page's listeners until the next lift anywhere (FR24).
…lift and the browser's menu, keeps a kept press's finger, and goes when the page hides - A finger's or a pen's armed press now brings the claiming listeners (the cancelable touchend and the contextmenu canceller) with the page listeners, as wherever the host installs, so a claimed lift clicks nothing and a claimed hold opens no browser menu (spec:AST-094 FR21). A mouse's press needs neither and adds neither. - A kept press keeps its finger under any pointer: its target blocks and its moves are cancelled once its press is delivered, not only where the primary pointer is coarse (FR11, DEC-21). - A page hidden mid-press releases the armed press as a blur does, so the page's listeners go with the cancelled press (FR24).
…'s selection An action group's press is a long press with no minimum duration, so it claims at the press's pointerdown, before any movement. The drag selection hold then cleared the page's selection, so a plain click on a group's button left its Copy or Cut with nothing to act on. The case fails on this head: the selection is gone after the pointerdown.
…age's selection The drag selection hold cleared the page's selection when any mouse or pen contact was claimed, but an action group's press claims at its pointerdown, before it has moved or selected anything, so a plain click on a group's button left its Copy or Cut with nothing to act on. A claim before any movement now keeps the page's selection: the hold still refuses a new one, and puts the page's back over a selection that appears while it runs. A claim after movement clears what its drag selected, as before (spec:AST-094 FR41). The case before the new one now waits for its hold to end a task after the lift, so no hold outlives that test.
…t every pointer does - GestureHost's header, the gestures README and coarsePointer.ts no longer describe the coarse-only host: a finger or a pen takes the touch-down lock under any primary pointer, a kept press's finger is kept during a fine pointer's press too, and recognizers attach for every pointer while the page listeners last a press (spec:AST-094 FR19, FR24, FR41, FR43). - The fine-pointer selection case asserted the replaced rule and passed only because it read iOS WebKit's inline lock without iOS WebKit: it now asserts the lock a fine pointer's finger and pen take, and that a mouse takes none. - FR41's sentence and its verification row say that a press claimed at its own pointerdown, before it moves, keeps the page's selection, while a drag that moved before its claim loses what it selected.
…ion, in the present tense The sentence said a drag that moved before its claim loses the selection it started, but the hold clears the page's selection then, whatever made it; and an unclaimed mouse drag kept "today's" behavior, a phrase that ages. It now says a claim after movement clears the page's selection, a press claimed at its own pointerdown keeps it, and an unclaimed mouse drag keeps its released behavior.
meta#8665's review fixes: an armed press under a fine pointer brings the claiming listeners, keeps a kept press's finger and goes when the page hides; a press claimed at its own pointerdown keeps the page's selection; FR41 says what a claimed drag does with the selection; meta#8360's input-stream notes. The merge is clean.

Approval waits on an engineering owner's decision about new drag-selection sentences in spec:AST-094 FR41, and the branch still needs splitting from the stack it depends on. This head adds to FR41 that a mouse or pen drag a recognizer claims takes no new text selection, clearing the page's selection once the drag has moved and keeping it when the press is claimed at its own pointerdown, which main does not state; an engineering owner approves it, with the amended verification row, by commenting /approve-spec 5760fdfb865d74afa00eb6a71b6918ddccd8e7fd on this pull request, or rejects it, and the author may record that decision as an engineering owner.

These three sentences are new direction for a mouse and a pen, and they wait on an engineering owner's decision: FR41 on main keeps a mouse's released behavior (spec:AST-017 FR59; DEC-9), and FR59 also asks the pull request to name its reason and show fine-pointer evidence before and after. The amended verification row now matches them; the keep-at-pointerdown case has only a jsdom test so far (packages/core/src/gestures/__tests__/GestureHost.test.ts:4066).

Depends on #8665. Review only this pull request's change: vjeux/astryx@c6c02fc...5760fdf
Why
In a group of links, a Ctrl-, Cmd- or Shift-click on a member should open that link in a new tab or window, as it does everywhere else in the browser. The gesture system could not tell such a click apart: a gesture touch carried no modifier keys, so a group that tracks a held pointer across its members (#8657) would take the click as its own.
What led to it
The review of #8657, ButtonGroup's press tracking across its buttons, found the gap. The group's half, declining such a click, follows in #8657 on top of this one.
Options and tradeoffs
Why this choice
The four keys are all a recognizer needs, read once from the pointer or touch event that began the contact; an input that leaves them out reads as none held. UIKit has no counterpart because a phone has no modifier keys, but on the web a mouse and a keyboard do.
How to check it
shouldReceiveTouchlogs the touch, then Cmd-click (Ctrl on Windows and Linux) the element. Expected: the logged touch hasmetaKey: true(orctrlKey: true) and the other keys false.Evidence
