Node.ip stores several comma-separated addresses once a user adds an
IPv6 (e.g. "fe80::1, 192.168.1.5"). All placement/inventory matching did
exact string equality on that field, so a device scanned as the plain
IPv4 looked absent from the canvas: canvas_count stayed 0, the "In N
canvas" badge and hide-on-canvas button vanished, and bulk-approve
re-placed a duplicate node.
Match per-address instead, and add MAC (a stable identifier immune to IP
edits) as a cumulative match key alongside ieee/ip:
- _canvas_correlation indexes ip per token + by_mac
- bulk_approve skip detection tokenizes ip + tracks mac
- find_duplicate_node narrows with Node.ip.contains then confirms per
token in Python (guards the 10.0.0.4 / 10.0.0.40 substring false match)
