safety controls visible and instantly recoverable.","archetype_mapping":"A protected visual absence isolates the current incident and ends when the assignment is completed or the dispatcher restores

assignment time by at least 10% without increasing wrong-unit assignments or missed safety alerts.","diversity_rationale":"Tests reversible control omission in real-time digital work, unlike the

shelters.","affected_stakeholder":"Evacuees with mobility, sensory, or medical-access needs","workflow_boundary":"Shelter floor setup through peak occupancy and replenishment","failure_mode":"Ad hoc infill blocks evacuation, assistance, visibility, or supply movement routes.","unit_of_analysis":"Traversal or assisted-transfer attempt through a shelter zone","causal_lever":"Treat marked circulation and decompression volumes as program assets that cannot be occupied without a formal trigger.","archetype_mapping":"An architectural void, bounded by surrounding functions, preserves movement, orientation, and rest rather than serving as leftover floor area.","expected_value":"More reliable accessible movement and emergency egress under occupancy pressure.","falsifiable_claim":"Shelter layouts with protected voids reduce obstructed-route events by at least 25% at matched occupancy without materially reducing usable bed capacity.","diversity_rationale":"Moves the intervention into physical space and tests route obstruction per traversal rather than interface attention or message comprehension.","mechanism_slugs":["architectural_void","margin_and_gutter_system"],"search_questions":["What shelter-layout standards already protect circulation or decompression zones?","How often

briefing content receives equal weight.","unit_of_analysis":"Team briefing followed by its first operational period","causal_lever":"Present only time-critical actions and constraints in the primary briefing while preserving removed context in a labeled, accessible annex.","archetype_mapping":"Editorial cuts create attention space around immediate actions while recoverability protects load-bearing evidence and contingencies.","expected_value":"Higher action recall and shorter handoffs without loss of necessary context.","falsifiable_claim":"A cut-plus-annex briefing improves unaided recall of critical first-period actions by at least 15 percentage points without increasing context-retrieval failures.","diversity_rationale":"Tests recoverable information omission at a

local coverage, no permission, or a system failure.","affected_stakeholder":"Residents checking official information during an evolving hazard","workflow_boundary":"Opening an official warning interface before any alert is displayed","failure_mode":"The resident interprets technical or permission-related silence as evidence of safety and delays protective action.","unit_of_analysis":"Warning-channel check session","causal_lever":"Diagnose the cause of absence and display a minimal status, timestamp, coverage statement, and appropriate next action.","archetype_mapping":"Empty-state design frames absence explicitly while preserving the surrounding hazard and jurisdiction context.","expected_value":"More accurate interpretation of silence and better-calibrated protective behavior.","falsifiable_claim":"Cause-specific empty states reduce false-safe interpretations by at least 20% versus a generic no-alert screen without increasing unnecessary protective actions.","diversity_rationale":"Targets public inference from missing data at the session level, not responder performance, physical movement, document recall, or meeting

hazards, or workarounds.","unit_of_analysis":"Facilitated review prompt round","causal_lever":"Require a bounded silent reflection interval, followed by participant-first contributions and a clear facilitator reentry trigger.","archetype_mapping":"Facilitation silence makes the powerful actor's temporary absence productive while meaning checks prevent coercive or confused silence.","expected_value":"Broader evidence capture and less rank-concentrated participation in learning reviews.","falsifiable_claim":"Compared with ordinary facilitation, protected silence increases the share of distinct operational issues first raised by non-command participants by at least 20% without increasing reported psychological discomfort.","diversity_rationale":"Uses temporal
