Agent Session Protocol
The storage and migration protocol for agent sessions — the session-layer counterpart to ACP.
ACP handles the live present; ASP handles the durable past and cross-runtime migration.
Append-log first
Correctness comes from the event log + evidence alone; snapshots are always re-derivable.
Opaque payloads
Unparseable bytes (signatures, encrypted reasoning) round-trip verbatim — never normalized away.
Declared fidelity
Cross-harness conversion states per-axis fidelity, and refuses rather than silently degrades.
