The bundle K9 seals at execution time covers most of what you described: X_t captures agent identity, session ID, hostname and PID at the moment of execution; Y_t hashes the constraint version in force; each record chains via SHA256 prev_hash so the bundle can't be reconstructed after the fact.

To be direct: K9 is currently designed for single-agent auditing. The delegation gap is real and unsolved.

For two-agent scenarios, the approach we're considering is treating the spawn itself as a first-class DELEGATION record in the chain — parent agent in X_t, granted scope in U_t, policy version in Y_t, and R_t+1 answers "was this delegation within policy?" The child agent's subsequent records carry a parent_delegation_id back to that sealed grant. Authority at execution time becomes reconstructable.

The harder question is what happens when B sub-delegates to C: the effective policy for C should be the intersection of the full chain — not just what C's config says, but A's rules ∩ A→B grant ∩ B→C grant, computed at execution time. We don't have a design for that yet.

You've clearly worked on this at a level beyond what we've reached. How have you approached the intersection problem in practice — do you compute effective authority at execution time, or seal the intersection when the delegation grant is issued?
