class_name TestHudGroupsAutoPause
extends GdUnitTestSuite
## T-970 (D-226 layer 1): HudGroups.gameplay_occluded must auto-pause/auto-resume
## the sim via SimBridge.send_named_action("AutoPause"/"AutoResume").
##
## AutoPause/AutoResume are protocol-level requests, not InputMapper keybinds —
## same mechanism as RequestBookmarkCatalog (send_named_action bypasses
## action_enum_to_wire entirely, so there is nothing to map there). This suite
## only covers the signal -> outbound-action wiring in hud_groups.gd; the
## server-side pause reconciliation (Option A) is covered by Rust tests in
## server/src/simulation/input.rs.
