v0.7.0-RC2

Release 0.7.0-RC2

Adds optional injection points so the A2A runtime can survive web-tier
restarts (Modal scale-to-zero, container eviction) without losing
in-flight tasks:

• A2AEventStore — durable per-(taskId, tenant) event journal. Wired into
  A2AServerApp.Settings; events are appended off the live publish path
  via a per-task delivery chain so SSE subscribers never wait on the
  store.
• A2AReplayProvider — pull-style stream source for tasks/resubscribe
  after the in-memory event bus is gone. Takes precedence over
  A2AEventStore when both are configured.

Hardening on top of the injection points:

• tasks/resubscribe for terminal tasks without a replay source returns
  a TaskSnapshot + EOF (wire-legal); for non-terminal tasks it now
  fails with unsupportedOperation pointing the caller at tasks/get,
  instead of returning a Working snapshot indistinguishable from a
  completed-but-replay-lost run.
• cancelTask events land in the durable store (cancellation no longer
  bypassed ResultManager).
• eventStoreAppendTimeout (2 s) and eventStoreLoadTimeout (5 s) are
  Config fields; misbehaving stores can't crash the persistence chain.

v0.7.0-RC1

Release 0.7.0-RC1

• Native A2A v1 protocol implementation
• Explicit A2A 0.3 compatibility via SDK-backed V03 APIs

v0.6.2

Release v0.6.2

v0.6.1

Release 0.6.1

SDK bumps:

• @anthropic-ai/claude-agent-sdk ^0.2.90 → ^0.2.116
• @openai/codex-sdk ^0.118.0 → ^0.122.0

New facade surfaces:

• SystemEvent.MemoryRecall + MemoryRecallMode / MemoryScope / RecalledMemory (SDK 0.2.105)
• SdkStatus.Requesting (SDK 0.2.108)
• QueryStream.streamUserMessage(shouldQuery = ...) (SDK 0.2.110)
• AgentOptions.title + withTitle(...) (SDK 0.2.113)
• AgentMessage.MirrorError for sessionStore mirror-error events (SDK 0.2.113)
• McpServerConfig.{HTTP,SSE}.tools + McpServerToolPolicy + McpToolPolicy (SDK 0.2.111)
• Model.Opus4_7 (new Model.opus alias) + Effort.XHigh (SDK 0.2.111)

Breaking semantic (documented in docs/COMPATIBILITY.md):

• options.env and CodexClientOptions.env now REPLACE process.env (SDK 0.2.113+)

Deferred to follow-up PRs:

• sessionStore subsystem (SessionStore / InMemorySessionStore / importSessionToStore / deleteSession)
• OpenTelemetry trace context propagation
• startup() + WarmQuery
