Extract the header fix into a standalone patch and colocate the
Electron, Deno, and Signal overrides in patches/abseil. Preserve the
x86-64-v3 restriction and document the accepted upstream fix while
waiting for bundled dependency updates.
Import the Abseil overrides through the patches overlay and register
the torchcodec override. Leave PostgreSQL output checks in
x86-64-v3-workarounds.nix.
Keep STFT tests enabled with precision-appropriate tolerances for
x86-64-v3 builds. Add the override under overlays/patches/scipy and
remove the commented-out test exclusions.
Wait for the UDP socket to bind before starting the client, detect
server exit, and clean up on skip. Preserve both handshake checks.
Add regression checks and document the rationale for upstream submission.
Validated on x86-64-v3: 796 passes, 131 existing skips, zero failures.
All seven focused checks and the delayed-start reproduction passed.
