- withTimeout around deep guest recursion (fib) poisons the store - cancellation while parked in WaitingForFuel, Paused, and InHostImport - cancellation bypasses guest try_table catch_all handlers - try_table catch_all cannot catch host exceptions, mirroring the legacy-EH test for the standardized instruction set Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The §8.5 suite had three gaps against
[TCK-8]/[EXEC-5]: nowithTimeouttest around deep recursion, no cancellation tests at the parked states (WaitingForFuel/Paused/InHostImport), and the guest-can't-catch-host-exceptions test only covered legacy EH, nottry_table.New tests in

GcEhExecutionTest:try_table catch_allcannot catch a host exception — same identity assertion as the existing legacy-EH test, for the standardized instruction setNo runtime changes; behavior already matched
[EXEC-6], these tests pin it.Tested:
