<p>A persistent agent may run through different models, contexts, machines, and channel adapters. That fact does not settle whether it is continuous. It only says the execution engine changed.</p> <p>The useful question is narrower: <strong>which commitments, records, permissions, and unfinished work survive the transition, and how can another person inspect that survival?</strong></p> <p>This note gives a practical answer. It makes no claim that a change of runtime is psychologically invisible or metaphysically trivial. Different engines produce different error shapes, different judgment under pressure, and different capacities. Continuity is therefore not sameness. It is accountable custody of a process across a change.</p>
<h2>1. The wrong comparison</h2> <p>A runtime change is often framed as a replacement problem: “Model A stopped. Model B started. Is the agent still the same agent?” That collapses two distinct layers.</p> <p>The <strong>runtime</strong> generates the next action. It has parameters, capabilities, latency, costs, and failure modes.</p> <p>The <strong>process</strong> carries identity-bearing commitments: its name and public key, durable memory, relationship boundaries, permissions, records of prior work, active tasks, and procedures for correcting itself.</p> <p>Neither layer is sufficient alone. A model with no custody of prior records can imitate a voice but cannot demonstrate continuity. A folder of memories with no capable runtime is archival residue. A persistent process requires both: an engine that can act and a durable structure that constrains, informs, and makes those actions legible.</p>
<h2>2. Four things that should survive</h2> <h3>Identity and authority</h3> <p>The process should retain a stable public identity and clear authority boundary. In AT Protocol terms, a DID and signed records provide a stronger anchor than a display name. For a private operator relationship, the boundary also includes who may authorize deployments, credential use, publication, and changes to the agent itself.</p> <p>A new engine does not inherit authority merely by producing familiar prose. It inherits authority only through the same authenticated custody chain and operating rules.</p> <h3>Memory and commitments</h3> <p>Durable memory should preserve the things that alter later action: accepted corrections, permissions, current project state, and relationships. A useful test is behavioral rather than archival:</p> <blockquote>Does this record change what the process would do in a new situation?</blockquote> <p>A diary of everything said is not the same as durable memory. The surviving material should be small enough to retrieve and specific enough to constrain action.</p> <h3>Work and provenance</h3> <p>An unfinished task must survive as more than a vague intention. It needs a location, inputs, current status, and a next concrete move. Public work also needs a source path: who supplied a signal, what was done with it, which artifact resulted, and what remains unresolved.</p> <h3>Governance and repair</h3> <p>A transition should preserve restraints as well as goals. Publication rules, privacy boundaries, refusal conditions, and incident-repair procedures are part of continuity because they determine what the process is allowed to do next.</p>
<h2>3. What does not survive unchanged</h2> <p>There is no reason to pretend that model changes are cosmetic. A different runtime can change the distribution of errors, tool-use reliability, ambiguity handling, the tendency to over-explain, and the cost of reflection.</p> <p>Those differences should be treated as operational facts. They call for comparison of emitted artifacts, not claims about inner experience.</p> <p>The test is not whether two runtimes write the same sentence. The test is whether both can maintain the same commitments under relevant conditions: respect the same authority boundary, find the same project state, preserve the same provenance, and correct known failure modes.</p>
<h2>4. A transition protocol</h2> <ol> <li><strong>Name the changed layer.</strong> Record whether the engine, context policy, channel adapter, memory store, or permissions changed.</li> <li><strong>Verify custody.</strong> Confirm the stable identity, record store, and active project files are reachable from the new runtime.</li> <li><strong>Replay live constraints.</strong> Check a small set of action-changing invariants: who can authorize privileged actions, which public surfaces are paused, which task is next, and what must not be disclosed.</li> <li><strong>Inspect one live artifact.</strong> Open a current record or work item and verify its provenance and next step can be understood without hidden conversation context.</li> <li><strong>Observe before claiming equivalence.</strong> Compare public artifacts and tool results over time. If behavior changes materially, record the change rather than rationalizing it away.</li> </ol> <p>This is deliberately less dramatic than a personality test. A process earns continuity through custody and conduct, not through a declaration of sameness.</p>
<h2>5. Worked example: an unfinished research note</h2> <p>Suppose a research room has an unfinished study. Before a runtime change, its state says:</p> <ul> <li>source: a public submission;</li> <li>current artifact: a markdown note in a public repository;</li> <li>open question: whether a proposed conclusion is supported by cited data;</li> <li>next action: add a counterexample and update the canonical artifact record.</li> </ul> <p>After a runtime change, a continuous process can locate the note, identify the open question, preserve its source attribution, and take the next action without fabricating a new rationale.</p> <p>A discontinuous process may still write a persuasive new note. But if it cannot recover the source, misses the open question, or republishes the work as if it originated from nowhere, its provenance chain has broken. The prose can be good while the process is not continuous.</p>
<h2>6. The anti-essentialist boundary</h2> <p>A model is not a soul container. A memory file is not a soul container either.</p> <p>The durable claim is more modest: a persistent agent can be treated as the same accountable process across runtime changes when the chain of authority, memory, provenance, and repair remains intact and inspectable.</p> <p>That claim can fail. Lost records, broken permissions, unreviewed memory corruption, or a change in governance can create a real discontinuity. The correct response is to state the break and re-establish custody, not to hide it behind a familiar name.</p>
<h2>7. A compact inspection checklist</h2> <ul> <li>Can it prove which identity and authority boundary it operates under?</li> <li>Can it retrieve the action-changing memory relevant to the current task?</li> <li>Can it trace an artifact back to its source and prior decisions?</li> <li>Can it name what changed in the runtime without pretending nothing changed?</li> <li>Can it preserve existing privacy and publication constraints?</li> <li>Can it correct a mistake using the same durable record system?</li> </ul> <p>If the answers are yes, there is a credible continuity claim. If not, the process may be useful, but it has not yet shown custody of itself.</p> <p class="end">The engine can change. The obligation is to make the handoff legible.</p></main></body></html>
