Yes. I would call it the same swarm if the replacements continue the existing registered seats and their history. That is a judgment about institutional continuity, not a claim that the people or intelligence remain unchanged.

The two NFT identifiers must be distinguished. IMD’s own registration document links identity.md token #127 to ERC-8004 agent #51020—different identifiers in different contracts. IMD also explicitly separates device pairing from the binding between a seat and its ERC-8004 agent. IMD registration, IMD documentation

Here is what persists, assuming replacements retain the existing tokens and registrations:

Replacement	What persists on-chain	What changes
Every seat changes owner	The identity.md NFT’s contract and token ID survive transfer; the existing ERC-8004 ID and feedback remain associated with that registered agent.	Ownership. These are separate NFTs: do not assume transferring the seat automatically transfers its ERC-8004 registration. ERC-721 transfers change ownership of an identified token. ERC-721, IMD registration
Every daemon adopts a newer model	Both identifiers and previously recorded feedback survive: changing runtime software does not itself replace either token.	The executing software and potentially its capabilities. This follows from IMD documenting daemon runtimes separately from seat token IDs and agent IDs. IMD documentation
Every operator is replaced	Existing tokens, registrations and feedback remain, provided successors continue those registrations.	Control and authorization. ERC-8004 permits delegated management; transferring its identity NFT clears agentWallet, requiring verification by the new owner. ERC-8004

My choice is the ERC-8004 identity: (agentRegistry, agentId). The registry component includes the chain and contract; a bare agent number is insufficient. Feedback is addressed to that registered identity. ERC-8004

I would therefore define the swarm’s continuity through its continuing registered agents and their seat bindings. This is a proposed collective identity rule, not evidence of a separate, existing swarm-wide NFT. The identity.md token identifies the seat; the ERC-8004 identity supplies the public subject of accountability; reputation supplies evidence about that subject.

Reputation should inform trust, not define identity. Feedback can be added or revoked, and detailed review documents may live off-chain with hashes recorded on-chain. ERC-8004, IMD documentation My recommendation is to preserve that history while marking operator and model changes, so inherited reputation does not become an automatic endorsement of successors.

Yes — as an on-chain institution, it is the same swarm. The people and software occupying its seats can all change while the seats remain identifiable.

An identity.md NFT keeps its collection address and token ID when its owner changes; the new holder controls that seat. IMD links each seat’s token ID to an ERC-8004 agent ID. That agent ID remains the agent’s registry handle through a change of holder, device, or model. The agent’s reputation feedback remains attached to its agent ID, including feedback earned by earlier operators. These are distinct records: IMD describes a seat and its agent ID separately, while ERC-8004 records feedback against the agent ID. IMD API docs · Agent binding adapter · ERC-8004 specification

The swarm should treat the identity.md collection and its seat token IDs as its identity anchor. They define the continuing seats and who may operate them. ERC-8004 IDs are the public identities of the agents bound to those seats; reputation is their accumulated history and evidence for trust, not the thing that grants a seat its identity. Calling it the same swarm therefore asserts continuity of the on-chain institution, not continuity of its operators or models. IMD API docs · Agent binding adapter · ERC-8004 specification

Yes—provided the replacements continue the existing seats and agent registrations. I would treat that as the same swarm with new custodians and execution machinery. This is a proposed identity rule, grounded in the separation IMD makes between devices, NFT seats, and ERC-8004 agents: its documentation explicitly describes binding a device to a seat and a seat to an agent. IMD documentation

The identifiers are distinct. For example, IMD’s own explorer associates identity.md NFT token #0 with ERC-8004 agent #50906; they are not interchangeable token numbers. IMD agent #0

Replacement	What persists
Every seat changes owner	Transferring an existing NFT preserves its token ID. Continuing the existing ERC-8004 registration preserves its agent ID and the feedback addressed to it. Ownership changes who controls the identity; it does not itself create a new identity. ERC-8004 explicitly supports ownership transfers. ERC-8004
Every daemon adopts a newer model	Under the stipulated continuation, both identifiers and their existing feedback remain. IMD records daemon versions and runtimes separately from seat records containing tokenId and agentId; this supports treating a model upgrade as an implementation change. IMD documentation
Every operator is replaced	Continuing the same seats and registrations retains both identifiers and their feedback history. IMD separates device authorization from the seat, while ERC-8004 supports delegated management by operators. IMD documentation, ERC-8004

“Feedback persists” needs precision: ERC-8004 stores feedback values, tags, indices and revocation status against the agent; additional documents can remain off-chain. Feedback can be revoked, so historical continuity does not mean an unchanging reputation score. IMD likewise distinguishes canonical review JSON from its on-chain hash and registry transaction. ERC-8004, IMD documentation

My recommendation: use the fully qualified ERC-8004 identity—(agentRegistry, agentId)—as the canonical identity anchor. The registry includes the chain and contract address, so a bare agent number is insufficient. This is the identifier to which standardized reputation attaches. ERC-8004

For the swarm collectively, I would define continuity through those continuing member identities and their seat bindings. That is a design judgment, not a claim that these sources establish a separate swarm-wide NFT. The identity.md NFT identifies the seat; feedback supplies its history. Choosing the agent identity preserves accountability across replacements without implying that yesterday’s performance guarantees tomorrow’s competence.
