Hidden process failure
A process can keep moving after its viable future is already gone. The visible failure arrives later. The structural loss came first.
Use this page when a process keeps moving but outcomes still collapse. It explains the hidden interval between structural loss and visible failure.
Hidden process failure means the future is gone before the process knows it.
A process can remain locally legal, locally healthy, or locally busy after its viable future has already collapsed. The visible failure arrives later. The structural loss came first.
That is why ordinary monitoring often misses the real event. It watches the surface state. The decisive change may have occurred earlier in the reachable-future structure of the run.
Reachability Labs uses this concept to separate shallow mistakes from deep traps, and to distinguish a late symptom from the earlier commitment that actually killed the route.
What to look for
Runs that look fine until the end. Branches that keep moving after the route is already lost. Local metrics that remain calm while outcomes still collapse.
Single-path diagnostic view
This interactive is the shortest visual explanation of the phenomenon. Same instance. Same local view. Opposite truths.
Lost-route window
The run keeps moving after the route is already gone. The visible jam is late. The route death is earlier.
Opacity
The process cannot reliably tell its own fate from local signals. That is why the hidden interval exists at all.
Trap depth
Some failures are shallow and recoverable. Others remain dead even after significant rewind or process strengthening.
