-### AI verification checklist (required if AI was used)
-- [ ] I understand the code in this PR and can explain it
-- [ ] I verified all referenced APIs/types exist and are correct
-- [ ] I reviewed edge cases and failure paths (timeouts, retries, cancellation, exceptions)
-- [ ] I reviewed concurrency/async behavior (no deadlocks, no blocking waits, correct cancellation tokens)
-- [ ] I checked for unintended breaking changes or behavior changes

-> If this is docs-only or test-only, explain why manual validation is N/A.

-### Environment
-- OS:
-- .NET SDK/runtime version:
-- DurableTask component(s) affected (client/worker/backend/etc.):
-
-### Scenarios executed (check all that apply)
-- [ ] Orchestration start, completion, and replay behavior
-- [ ] Activity execution (including retries)
-- [ ] Failure handling (exceptions, poison messages, transient failures)
-- [ ] Cancellation and termination flows
-- [ ] Timers and long-running orchestration behavior
-- [ ] Concurrency / scale behavior (multiple instances, parallel activities)
-- [ ] Backward compatibility check (old history / upgraded worker) if applicable

-# Review checklist (author)
-
-- [ ] Code builds locally
-- [ ] No unnecessary refactors or unrelated formatting changes
-- [ ] Public API changes are justified and documented (XML docs / README / samples as appropriate)
-- [ ] Logging is useful and not noisy (no secrets, no PII)
-- [ ] Error handling follows existing DurableTask patterns
-- [ ] Performance impact considered (hot paths, allocations, I/O)
-- [ ] Security considerations reviewed (input validation, secrets, injection, SSRF, etc.)
+## Manual validation (only if runtime/behavior changed)
