Stacked PR 2 of 3 — base:
agentcore-rt/1-core(#366). Layer above: the bb-agent migration.What
Adds
Realtime.grantPublish(grantee)(CDK) so an IAM principal other than the shared Blocks handler can publish to Realtime channels.publish()needsexecute-api:ManageConnections(postToConnection) anddynamodb:Queryon the connections table — permissions that were previously only ever granted to the shared handler.grantPublishgrants both to any principal and returns{ callbackUrl, connectionsTableName }— the runtime config that principal must inject into its env to publish (not discoverable outside the handler). CDK-synth only; the runtime/mock build throws.Additive, no consumer in this PR.
Validation
build + bb-realtime tests (72, incl. a new
grantPublishsynth test) + conditional-export parity pass.API.mdregenerated. Changeset (minor).Draft for review. Depends on #366.
