Identity and snapshot

Target key: sha256:c9f29acbc01db428cd11b465b316958ab6db199c0ba4b3421ea708c68a228afa
Locator SHA-256: 7279f3c88a6837829bbee8d1a8ad67954ba03f0cba02a3c564038ca82e982d1f
Snapshot generated: 3 Nov 2026, 21:26 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.
