SAVER_NAVIGATIONMODEL

SAVER_NAVIGATIONMODEL: recorded condition

SAVER_NAVIGATIONMODEL has value 0x0000F006 and identifies navigation-model state failure. For SAVER_NAVIGATIONMODEL, 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 for SAVER_NAVIGATIONMODEL

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.

  • For SAVER_NAVIGATIONMODEL, record the exact Windows build, process or package identity, module versions, capture timestamp, and component that requested the report.
  • For SAVER_NAVIGATIONMODEL, 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.
  • For SAVER_NAVIGATIONMODEL, 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 SAVER_NAVIGATIONMODEL

Do not merge this automatically with an input or rendering bucket: navigation state can fail while both remain functional. For SAVER_NAVIGATIONMODEL, 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 for SAVER_NAVIGATIONMODEL

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