The workspace files constraint keys worker bundles on the ./worker export
(lib/worker.cjs, the workflow-workerthread shape); the descriptive source
entry stays win32-dialog-worker.ts and tsdown renames the bundle.
On a fast host the 1ms close budget can exhaust and reject between waitFor
ticks; a rejection with no listener yet counted as an unhandled error in the
Linux run.
The modern IFileOpenDialog becomes the primary win32 tier: a koffi-driven
COM conversation on a worker_threads worker (the modal Show never blocks
the host event loop), per-monitor-v2 DPI via SetThreadDpiAwarenessContext,
and abort service by re-posting WM_CLOSE to the dialog thread's windows,
with terminate+unref as the last resort (Node cannot interrupt a thread
blocked in native code, and such a worker must never hold the process open).
The PowerShell chain stays as the fallback tier with its trigger widened
from ENOENT to any pwsh failure, closing the review-flagged PowerShell 6
regression (no WinForms: exit 1, not ENOENT, so 5.1 never ran).
Layering keeps per-file coverage honest on every host: pure sequencing and
the driver test against fakes anywhere; the bindings run against a mocked
koffi COM world (the session-persistence-jsonl technique); POSIX hosts
drive the real spawn plumbing to its koffi-load rejection; win32 hosts run
a real open-and-abort-close smoke. The smoke joins processBoundTests: a
worker blocked in a native modal wedges the threads pool's teardown, while
a fork contains it. The worker bundles as its own CJS tsdown entry
(workflow-workerthread's pattern; no TLA), and the host module is imported
statically so the node-half bundle stays chunk-free.
Built-plane and real-COM behavior verified on native Windows: standalone
probes for the source worker, the built CJS worker, and the driver's abort
path all open and close the real dialog.
Agent Notes: new implemented/feature/2026-08-02-win32-in-process-folder-dialog
(bilingual) owns the decision; the DPI note is re-scoped to the fallback tier
it now describes and its AutoUpgradeEnabled attribution corrected (.NET Core
3.0 rewrote FolderBrowserDialog; the opt-out arrived in .NET 6).
.NET 10's modern FolderBrowserDialog renders Description as a bottom
strip above the folder input, and the 5.1 classic dialog as an unthemed
white box; the property is dropped entirely and a regression assertion
pins its absence.
README pairs document the pwsh-preferred adapter and the PowerShell 7
requirement for the modern dialog; the 2026-07-27 picker note's Windows
adapter fact is updated in place, and a new bug-fix note records the
defect, the fallback decision, and the DPI awareness rationale.
The win32 branch now spawns pwsh.exe (PowerShell 7) first and falls back
to powershell.exe (Windows PowerShell 5.1) only when pwsh is missing
(ENOENT), mirroring the Zenity-KDialog fallback. PowerShell 7 renders the
modern IFileDialog folder picker; the 5.1 fallback keeps the legacy tree
functional. Both runtimes execute the identical script, which opts the
process into system DPI awareness (SetProcessDPIAware) before any window
exists, fixing the blurry bitmap-stretched dialog on scaled displays.
#1381 landed the bar's horizontal position; this branch decides when it is
drawn. The e2e keeps both scenarios and the golden carries both palettes'
pointer-state readings alongside the new edge-offset lines.
Review findings from the first round:
- ui-settings renders its full-viewport panel as a fixed-position DESCENDANT
of the sidebar column, so `pointerleave` never fires when the pointer moves
onto it and the bars stayed drawn after it closed. Leaving is now decided
against the column's box from a document-level pointermove that exists only
while the bars are drawn; the element's own leave stays for the pointer that
leaves the window.
- The rebind gate judges the rule rather than each declaration, so a pair that
mixes `transparent` with an l2 hover no longer passes, and the elevation
half compares whole values instead of token shape.
- Hiding no longer exempts a sheet from the elevated-surface rebind check.
- The e2e polls the reveal before reading a colour for the golden, and pins
that a pointerless scroll draws no thumb.
The session list overflows after a handful of sessions, and its scrollbar
was drawn permanently in a column that is at rest most of the time.
SidebarRoot now tracks the pointer over the whole column and rebinds
ui-theme's scrollbar indirection pair to `transparent` while it is
outside, keeping the thumb for 2s after the pointer leaves so it does not
blink out on the way past. Rebinding colour leaves the list's
`scrollbar-gutter: stable` reservation in force, so revealing the bar
moves no row.
ui-theme's gate now states the widened contract: a rebind targets an -l2
token pair or `transparent`, and nothing else.
