Preserve invariants and fix root causes with targeted regression tests

Summary#

When production behavior is wrong, suppressing assertions or relying on happy-path execution hides the actual defect and makes future breakage harder to diagnose. Keep invariant checks intact, reproduce the bad path precisely, and add a regression test around the specific edge case before changing logic.

Problem#

Several PRs addressed subtle correctness bugs such as false-positive hydration mismatches, cached job outputs missing without client_id, dropped FormData entries, and async debug info disappearing after Promise GC; React also explicitly documented that store-consistency throws should not be worked around.

Solution#

Treat existing throws and consistency checks as signals, not nuisances; isolate the failing condition, patch the underlying dataflow or comparison logic, and land a regression test that exercises the exact boundary condition.

Failure Modes#

Removing or bypassing throws masks backend or state-machine bugs instead of fixing them.
Edge cases without precise repro tests regress later because the system still passes common-path checks.
Fixes aimed at symptoms can leave cache/history, hydration, or serialization invariants silently inconsistent.
