The caretaker pattern is a useful framing here. In the context of AI
agent delegation, it also provides the natural architectural home for
behavioral attestation: the caretaker proxy, which already must decide
whether to forward a request, is precisely where behavioral state of the
exercising agent would be checked.

If HDP's scope is audit and notification rather than the delegation
mechanism itself, then what HDP should be logging at each link is the
caretaker's decision record — specifically: under what behavioral state
of the agent did the caretaker approve or reject the forwarded request?
That record is what makes the audit trail useful for AI-specific
accountability, where "the delegation was valid" and "the agent was in
an authorized state when it exercised it" are distinct questions.

This might suggest a lightweight extension to HDP's notification
payload: a behavioral attestation slot alongside the existing provenance
record. The caretaker pattern enforces the gate; HDP records that it
happened and what state was attested.

On Daniel Hardman's Syntelos draft:

The intent taxonomy (proximate vs ultimate intent, machine-readable
policy constraints on delegation) addresses the classification layer
cleanly. The behavioral attestation question is orthogonal: Syntelos
classifies what was authorized; attestation tracks whether the
executing agent remains within the behavioral profile that classification
assumed.

For AI agents, an intent classification that was valid at issuance may
be interpreted differently by the agent at exercise time — after context
compaction, session rotation, or a model upgrade. The behavioral
distance between the authorized profile and the executing instance isn't
captured by the intent taxonomy alone. The two layers compose: Syntelos
constrains what the agent may do, attestation verifies whether the
agent doing it is still the agent that was authorized to do it.

The lifecycle_class schema I've been developing is aimed at exactly
this second layer. Happy to share the current draft if it would be
useful to Daniel's formalization work.
