The scan_network_devices, verify_device_reachable, and rebind_device_to_scan templates used plain "..." strings for PROJECT_FILE_PATH. With a UNC path like \\files\... the rendered Python source had "\\files\..." which Python's source parser collapses to "\files\..." (one backslash). ensure_project_open then saw the mangled path as different from the (correctly-opened) primary, CLOSED the primary project, and failed to reopen the corrupted path. Other scripts use r"..." to bypass source-level escaping. Applying the same to the three new ones. Also bumps to 0.9.5.

# verify_device_reachable: pre-flight check before connect/download.
|
|
#
|
|
# Locates the configured target device, runs a live network scan on its
|
|
# gateway, and reports whether the cached device address appears in the
|
|
# scan results. If it doesn't, the binding is stale and a rebind is needed
|
|
# before any login()/download() attempt.
|
|
#
|
|
# Returns a JSON block with:
|
|
# reachable: bool
|
|
# cached_address: str (what the project thinks the device is at)
|
|
# matched: list (scan results whose address equals cached_address)
|
|
# candidates: list (scan results -- caller can pick one for rebind)
