+# Elder Bed Context Optimization Design
+
+## Summary
+
+Add read-only cross-module context to the existing elder and bed workspaces. The implementation should not merge workflows; it only surfaces concise recent signals from persisted admissions, care tasks, health records, and emergency incidents.
+
+## Data Boundary
+
+Use existing persisted tables:
+
+- admissions / beds / rooms for current bed state.
+- care_tasks for recent and active care execution.
+- vital_records and health_anomaly_reviews for health context.
+- system_incidents for safety/emergency context.
+
+No schema change is required. `system_incidents` does not have elder/bed foreign keys yet, so emergency context is shown only when an incident's title, description, or source clearly mentions the elder name, bed code, or room label.
+
+## Permission Boundary
+
+Server pages decide which context to load:
+
+- `admission:read` / `facility:read`: bed/admission context.
+- `care:read`: recent care task context.
+- `health:read`: health anomalies and latest vitals.
+- `incident:read`: matching open/acknowledged emergency context.
+
+Users without a permission should not receive that context in props.
+
+## Server Helper
+
+Add `modules/operations/server/context.ts`:
+
+- `listElderBedContextData(input)`
+- input:
+  - `organizationId`
+  - `permissions`
+  - `elders`
+  - `beds`
+  - `admissions`
+- output:
+  - `elderContexts: Record<string, ElderOperationalContext>`
+  - `bedContexts: Record<string, BedOperationalContext>`
+
+The helper should batch queries and keep bounded result sizes.
+
+## UI Design
+
+### Elder list
+
+Add a compact "近期联动" column:
+
+- current bed/admission is already shown in the bed column.
+- show up to three concise lines:
+  - latest active/recent care task.
+  - latest health anomaly or vital summary.
+  - matching open/acknowledged emergency event.
+- If no permitted context exists, show `-`.
+
+### Bed workspace
+
+Add an occupant context column to the bed status table:
+
+- show current elder care level/status.
+- show active/recent care task for that occupant.
+- show matching emergency event for occupant or bed when present.
+- Keep actions in the existing workflows; context is read-only.
+
+## Compatibility
+
+- Existing elder CRUD remains unchanged.
+- Existing admission workflows remain unchanged.
+- Client refresh continues to update elder/bed/admission tables; cross-module snippets are refreshed on page reload.
