…bleDir volume
Python declarative substrate SandboxAgents now keep ADK session state in a sqlite DB inside the session
actor's durableDir volume. Go-runtime and BYO sandbox agents session state persistence is currently not implemented.
In addition, on config rollout old sessions remain on the existing actor instead of rolling over to a new actor based on the new golden snapshot.
Below are a list of the changes.
- One session ⇔ one actor: actor ids derive from the session alone and actors
resume under their birth template, so session state survives per-turn
suspend/resume and config rollouts; shape changes (image/command/env) apply
to new sessions only. The per-rollout orphan reaper is removed.
- Config reaches actors through a stable per-agent Secret plus Data-scope
suspends: a config rollout reuses the existing actor and picks up the new
config on its next cold-boot resume (~30s secret-cache bound).
- Session rows and tasks stay in postgres; the sandbox A2A transport now
creates the session row for headless (raw A2A) sessions, since the runtime
no longer does so as a side effect.
- New GET /api/sessions/{id}/events?source=sandbox reads events from the actor
(resume → fetch → suspend only if the read woke it, single-flighted), and
GET /api/sessions/{id} carries an events_source discriminator.
- Bump agent-substrate to v0.0.8; adapt to the ActorRef/atespace API, paginated
ListActors, and server-defaulted snapshot scopes.
