Identity and snapshot

Target key: sha256:f7262b40f63183564dd0781d12d446697deaec2dca1ff08b4f757a0b55567557

Snapshot generated: 4 Nov 2026, 00:59 UTC

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
