📝 WalkthroughWalkthroughThe change propagates runtime ChangesProvider replay checkpoint lifecycle
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This change durably persists private replay checkpoints, but an HTTP-configured API destination could expose checkpoint data and run-scoped authorization credentials in transit. Merge readiness therefore requires HTTPS enforcement or explicit security-owner acceptance, and one test assertion concern remains open. Sequence Diagram(s)sequenceDiagram

Automated Code Review — Score: 81/100 (Good, minor suggestions)Solid, well-scoped change that threads a Strengths
Concerns
Suggested action before merge: add the resume-continuation test (concern #2) since it's the one explicitly promised by the PR description and currently unverified, and get a quick confirmation on the unhandled-rejection question (#1) from whoever owns the runtime package. Neither blocks merge on its own, but together they're the difference between "good" and "excellent" here. Note: PR is Generated by Claude Code |

Code Review ✅ Approved 2 resolved / 2 findingsPersists direct-stream replay checkpoints by carrying trusted runtime message identity through the control-plane stream, snapshotting the host emission gate before environment isolation, and forwarding server-resolved checkpoints into the direct runtime. Provider replay enqueue error handling and resume path behavior with disabled emission have been addressed. ✅ 2 resolved✅ Edge Case: Provider replay enqueue bypasses clientAttached error handling
✅ Quality: No test for resume path (emission disabled, checkpoint matches)

provider stream failures are processed independently of ToolCallEnd: do not wait
indefinitely for the replay flush before consuming the later runtime error, or
explicitly settle the provider replay relay when the stream fails. Ensure
failures before persistProviderReplayCheckpointAfterTurn can invoke
__vfProviderReplayCheckpointTurnFailed, and add a regression case covering
step-start, tool-input-* and error frames without a completion callback.
