Runtime monitoring. Recovery under test.

Sentinel studies whether a geometric monitor around a frozen driving planner can improve outcomes. Inspect the system, recorded decisions, benchmark gains, transfer nulls and failed recovery experiments.

What the live surface shows

  • A geometric monitor around a frozen planner.

    Observe decoded outputs, detect geometric threats, latch and release the stop, inspect applied control, and compare paired outcomes.

    The implemented trigger uses decoded objects and plan geometry. Privileged diagnostics are separately scoped.
  • The gain and its costs belong together.

    NeuroNCAP score gain, frontal collision increases, safe-progress uncertainty, HUGSIM transfer nulls and unresolved placebo attribution.

    Every finding links to its retained result. Nulls and failures remain visible.
  • Inspect the collision witness and historical trace.

    Iter155 shows two recorded native boxes and background Gaussian centers; Iter42 exposes 17 logged monitor decisions.

    Neither the historical trace nor the background reconstruction establishes a prevented collision or useful recovery.
  • Information and recoverability, through Iter155.

    Follow the change in question, the execution work, the failed native maneuver and the proposed calibration before another search.

    The searchable experiment index retains corrected, withdrawn, null, inconclusive and failed results.
