The workspace browser's two hover-raised popups both died on the way to
them. HoverCard closed on the first pointerleave and rendered its card
pointer-events:none, but the card sits 8px off the anchor, so every path
to it crossed ground belonging to neither. The row action menus put
closeOnPointerLeave's handler on the portaled list, so aiming back at the
... trigger that opened it, or overshooting a list edge, closed it with no
window to come back.
usePointerGrace owns one cancelable delayed close (200ms) shared by both
atoms: leaving arms it, returning cancels it. The hover card becomes
hit-testable so resting on it holds it open, and Menu moves pointer-leave
dismissal to the wrapper span, where React's enter/leave traversal makes
trigger and portaled list one region.
Both gestures are pinned in the real browser lane; each fails without the
corresponding fix.
The workspace header row is now wrapped by its HoverCard anchor span
(0b4a6196f), so the row's immediate parent no longer holds the session
subtree; the delete scenario anchors on the groupSection ancestor
instead. The flat-view and dwell failures were downstream of this one
(shared page state).
The master-side refresh batch recorded these goldens against master's
composer (customTrigger row, header pager); the merge keeps this
branch's redesigned composer (always-visible custom input, footer
pager) with copy on the standard locale seat, so the waiting aria and
the answered transcript re-record against the merged UI. The answered
golden also picks up the ask_user_question toolview row this branch
introduces.
The English-locale golden refreshed on master (8c753fd8f1) was recorded
against master's pre-miller dialog; this branch's own golden predated the
miller two-pane landing and was never enforced before the web browser
snapshot CI gate landed. Re-recorded against the merged tree: two-pane
landing plus the show-hidden footer toggle.
The seven behavior-pinning snapshots (workspace-flow, slash-flow,
todo-display, session-title, session-actions, terminal-card,
code-mode-fixture) asserted per-package behavior through the whole
built app: every assertion now lives in the owning package's suite at
equal strength (SlotTestRuntime benches assemble the same plugin apply
over the production slot machinery), while the assembled layer kept
re-failing on unrelated churn at 10s-timeout debugging cost.
What only this lane can prove is the artifact plane: lib/client.js
bundles loading through the ModuleLoader path, staged boot activation
across the inject layers, per-plugin CSS injection, and a journey
reaching chat content over the fixture transport. built-boot.snapshot.ts
pins exactly that, and nothing else — behavior assertions belong to the
package suites.
