1-Click SeedVR 2.5 — Release Notes (v1.9.63b)

Everything new since v1.9.62b.

v1.9.63b — 7B download crash root-caused & fixed, never-die errors, split-line anywhere, model deletion

PySide6 marshals Signal(int) arguments to a 32-bit C++ integer.
The 7B model sizes (4.8–16.5 GB in bytes) exceed the 32-bit limit, so
every progress update raised OverflowError → "Unhandled Exception"
dialog → freeze → app closed. This is why small models (≤2 GB) downloaded
fine while every 7B download died.
The progress signal now transmits megabytes (comfortably inside the
32-bit range). Verified live against HuggingFace: partial download of
the exact failing model (7B Q4) runs clean with zero exceptions, and
cancel/resume still work. All 10 catalog links re-verified (200 OK,
sizes match).

The error dialog is now non-modal: an unhandled exception no longer
enters a nested event loop (that re-entrancy froze and killed the app
right after showing the dialog). The application keeps running so the
user can read the report and press Send Logs.
Only one error dialog at a time — cascading exceptions during a
crash no longer spawn a dialog storm.
Hard C++ crashes (access violations) are captured by faulthandler
and appended to error.log (no separate crash.log; Send Logs ships
them automatically).

LMB press anywhere on the image grabs the split line — no precise
aiming, the line jumps to the cursor and follows the drag at any zoom
level. Video play/pause stays on the control button and the Space key.
RMB pans while zoomed; double-click still recenters.

Downloaded models can be checked and deleted (with the model's
stale .download partial cleaned up too). A confirmation dialog
lists the names and sizes and shows the disk space to be freed before
anything is removed; the DiT list refreshes afterwards.

Disk-space pre-check: if the selection needs more space than the
drive has free, downloading refuses to start with a clear
"Needed X GB / Free Y GB" message.
Model-manager signal handlers are guarded against the dialog being
closed mid-download (late signals can no longer crash anything), and
the window was narrowed.

Live network tests: 7B Q4 partial download + cancel + Range-resume.
Real Qt mouse events: split-line grab-anywhere at 3× zoom.
Crash simulation: two consecutive slot exceptions → one dialog, app
alive, both tracebacks in error.log.
Delete flows: confirm/decline/partial-cleanup/empty-selection.
