Struct BlobTombstoneJson 

pub struct BlobTombstoneJson {
    pub stored: StoredBlobRef,
    pub deleted_at: String,
    pub author_pubkey: String,
    pub signature: String,
}

Serialized form of a blob_tombstones/{exact_object_hash}{suffix} object: the durable, signed record that a blob was deleted, plus when, so a GC pass can reclaim the blob once the convergence grace has passed.

author_pubkey/signature cover the BlobTombstoneFields canonical payload — including the exact stored reference (the slot the tombstone lives under and the provider object it authorizes deleting) and deleted_at (so the age can’t be forged to dodge or shorten the grace). The GC verifies this signature and authorizes the author against the membership chain before deleting anything.

store_id is part of the signed payload but not stored: the reader supplies its own store id to Self::verify, mirroring the snapshot meta/pointer. A member of two stores cannot take one store’s tombstone and replay it as the other’s — re-verifying under the second store’s id fails, because the signature was taken over the first’s.

author_pubkey is stored: a tombstone’s author varies device to device, so the verifier learns who signed it and then checks that author against the chain (the authorization step).

Fields

stored: StoredBlobRef

The exact stored blob authorized for deletion. Its logical key determines the tombstone slot; its object reference determines which provider object GC may delete once the grace has passed.

deleted_at: String

RFC 3339 wall-clock time the deletion was recorded. The grace is measured from here; it is signature-covered so the age can’t be forged.

author_pubkey: String

Hex-encoded Ed25519 public key of the device that wrote this tombstone.

signature: String

Hex-encoded detached signature over BlobTombstoneFields.
