SAVER_NAVIGATIONMODEL: recorded condition

SAVER_NAVIGATIONMODEL has value 0x0000F006 and identifies navigation-model state failure. The SAVER family is used as a diagnostic classification; public parameter semantics are not available for this value, so the producer, dump type, and accompanying event payload define how it must be read.

Evidence that matters

Preserve current view, navigation and back stacks, activation arguments, transition token, shell state, and UI-thread activity. Reconstruct the attempted transition and identify the first view, model object, or activation callback that stopped advancing.

  • record the exact Windows build, process or package identity, module versions, capture timestamp, and component that requested the report.
  • determine whether the artifact is a live kernel dump, application dump, WER report, test-harness result, or a true system bug check before choosing debugger commands.
  • follow the stack and provider-specific fields back to the operation that stopped progressing; the symbolic bucket is a routing clue rather than a root-cause verdict.

What distinguishes the result

Do not merge this automatically with an input or rendering bucket: navigation state can fail while both remain functional. Compare neighboring SAVER values only after the evidence above identifies the same producer and lifecycle stage; similar-looking names can describe different capture triggers.

Recovery after evidence collection

Preserve the original dump and logs before restarting the affected process or machine. A restart may restore service, but durable recovery requires correcting the component, dependency, resource limit, firmware, or application state demonstrated by the captured evidence.
