Ubuntu removed the superseded 0.9.0-1ubuntu0.1 payload from its live
archive pool, so the shared Linux CI preparation step fails with HTTP
404 before tests start. Address Ubuntu's recorded Launchpad build so
future pool pruning does not invalidate the pinned download location.
Select upstream's 0.12.0 security release for CVE-2026-87766 instead of
Ubuntu's isolated 0.9.0 backport, whose regressions and support limits
are documented by upstream in Launchpad bug 2166359. Keep checksum
verification, direct extraction, and the existing namespace probe.
Verify build 33546835 against its published SHA256 and archive SHA512.
Its amd64 ELF requires at most GLIBC_2.38 and x86-64 baseline; its
packaging requires Linux 5.10. Ubuntu 24.04 provides glibc 2.39, Linux
6.8, and the required libcap2/libselinux1 versions. This changes only
the CI helper's pinned payload, not product sandbox configuration.
The slow-backend regressions start real NodeRuntime subprocesses, but
vi.waitFor silently imposed a one-second deadline on normal scheduling and
tool execution. Under concurrent Linux and Windows coverage this rejected
valid runs before the tested spill or dispatch stage was reached.
Resolve promises at the actual save-entry and dispatch-start observations,
and fail immediately if the run completes before those observations. Queue
all three requests up front in the bounded-backlog case so a missing third
start tests backpressure rather than child request timing. Cleanup releases
both queued and future spill gates and awaits execution completion.
Keep the existing outer test deadlines, product limits, result assertions,
and ordering checks. A temporary 1.2-second tool delay reproduces both old
failures and passes with these tests; temporarily removing the actual
backpressure wait still fails the third-dispatch assertion. No experiment
or product-code change is included.
Fixes#4585
The master merge invalidated docs/subsystems/slots.md's recorded pairing hashes; the minimal-preset UI golden still expected the breadcrumb as a disabled button, which darwin drag-band avoidance intentionally turned into plain text; and the app-region nudge effect's unattached-ref return had no darwin first-render test.
Master's sessionless-sidebar work renamed the conversation leading seat to
root-scoped conversation.header.leading instead of deleting it; the note now
states both seats' current roles rather than claiming outright removal.
The fixed fullscreen right panel sits over the frame's leading band and the
sidebar logo row's drag rects, so without a whole-box no-drag its
non-interactive content dragged the window; restore the subtraction (darwin).
The shell.leading note and AppFrame comment now state the real mount
condition (darwin && sidebarCollapsed) instead of the platform-agnostic
collapsedWidth === 0 claim, which Windows' caption collapse also satisfies.
Clear pointerFocus on pointerup/pointercancel so a press that never moves
focus cannot swallow the next keyboard focus; match prefixed/unprefixed
app-region with !important tolerance and prove the allowlist path rejects
an offender; scope the ui-layout shared-curve limitation to data-animating.
master's elevation contract (elevation-styles.client.spec.ts) rejects a
neutral border beside an lv/elevation shadow: the stroke belongs to the
shadow. The registry options keep their l3 hairline through
--dsw-elevation-stroke-color, as Menu does, with border: 0.
The cancelled-between-attempts case raced a zero-delay timer against the
file restore between two registries; under parallel load the restore won,
the second attempt started, and the once-only mock let it reach the real
pnpm. The stop now lands while the registries are read, before any run,
which is the same guard and cannot race.
