nav-backtrack

Recovery tool that searches world_state("nav") history for a safe prior cell and attempts to reach it using atomic nav primitives.

Input

  • •max_targets: Integer maximum number of safe targets to try (default: 3)

Output

Success (status: "success"):

  • •value: Summary text
  • •extra.recovered_to: {x, y, z, yaw} position recovered to
  • •extra.method: "step" | "climb" | "descend"
  • •extra.yaw: Final yaw

Failure (status: "failed"):

  • •reason: One of "NO_HISTORY", "STATUS_FAILED", "NO_SAFE_TARGET", "UNREACHABLE"

Behavior

  • •Reads world_state("nav") and chooses up to max_targets safe entries
  • •Uses nav-turn + one of: nav-move, nav-climb, nav-descend
  • •Verifies cell match via mc-status

Planning Notes

  • •Requires navigation history to be maintained by nav tools
  • •If recovery fails, consider mc-place-until-supported or broader replanning
