+## Usage
+
+### ParticipantHistory Module
+
+The `participanthistory` export provides the `ParticipantReports` component for displaying animal history data with search, filtering, and reporting capabilities.
+
 ```js
-import { TestComponent } from '@labkey/ehr';
+import { ParticipantReports } from '@labkey/ehr/participanthistory';
+
+export const AnimalHistoryPage = () => {
+    return (
+        <div>
+            <ParticipantReports />
+        </div>
+    );
+};
 ```
 
+**Features:**
+- Multi-mode filtering (ID Search, All Animals, Alive at Center, URL Params)
+- ID and alias resolution
+- Tabbed report interface with category grouping
+- URL-based state persistence for shareable links
+

+Github Issue/Epic: 
+
+## Modules/Distributions information
+
+Modules involved:  
+Base branch: develop  
+Feature branch(es): fb_ehr_an_hist_id_search
+
+# Feature Summary
+Implement a React Animal History using the React Participant View and a new Search by Id filter. Supports single and multi-animal selection and reports.
+
+## User Value Statement
+
+*Provide a simple statement that summarizes why a customer would need this feature. What will we tell a customer about this feature? What problem are we solving and how will we solve it?*
+
+Replacing and refining the existing ExtJS animal history with more modern React animal history to reduce technical debt and provide a better framework for future development. Combine and simplify single and multi animal Id search.
+
+## Success Metrics
+
+*Success metrics drive the understanding if something we have released has been successful or not. The success metric captures what we need to observe and monitor once the product has been released. For example, **reduce support queries on updated login page by 15%***
+
+Full feature replacement for single and multi animal search by Id. This is not yet at the MVP, so metrics for adoption or usage are not realistic at this point.
+
+## Background
+
+Migrating EHR to React has been prioritized as a long term effort starting in 2023\. There are a variety of reasons for migrating away from ExtJS, which has not been supported for a long time. React is the framework used within LabKey for modern UI design and is the most widely supported modern web framework.
+
+Animal History was chosen as the first UI to redesign due to its broad applicability across centers and across users within each center.
+
+Beyond migrating to a new framework, this will be an opportunity to rethink and improve the design of Animal History. User feedback will be key to determining the use cases that need to be supported and the ease of use supporting those use cases.

+## User Stories
+
+*How will a user incorporate this into their broader workflow? What types of users exist, and how does their usage differ? Include the **why**. Try using the format: As a \<user\> I want to … so that….*
+
+1. As a member of clinical, behavioral, research or colony management teams, I want to view animal history reports for a single animal.  
+2. As a member of clinical, behavioral, research or colony management teams, I want to view animal history reports for multiple animals. I may type in the Ids or copy and paste them in.  
+3. As a member of clinical, behavioral, research or colony management teams, I want to find animals by alias.  
+4. As a member of clinical, behavioral, research or colony management teams, I want to view all animal history reports with the filters above applied, including single and multiple animal variations of the reports.

+2. Risk: Incorrect data sent to reports  
+   1. Impact: High  
+   2. Likelihood: Medium  
+   3. Mitigation:   
+      1. Implemented as experimental feature to be able to view old and new animal history reports side-by-side.   
+      2. Manual testing with test data.  
+      3. Regression test coverage across all reports for each center.
+
+# Detailed Functional Design
+
+![][image1]
+
+The snapshot above is not a redline design but the features and layout represent what will be implemented in this story. The tabbed view of reports below the filters is already implemented for participant view, this new view will use the same component.
+
+1. Single animal search: This will use the same data entry as the multi-animal search. Copy/type in a single Id and click Search By Ids. The single Id will be added to the selected list as the only id.  
+2. Multi-animal search: Using the same text area as single animal search. Type or copy in multiple animal Ids. The animal Ids can have letters, numbers, special characters, and spaces in the names. Separators between animal Ids are newlines, tabs, commas and semicolons. Maximum of 100 animal IDs per search. If more than 100 IDs are entered, a validation error will be displayed and the search will not execute.  
+3. Resolve by Alias: Animals can have a number of aliases \- nicknames, tattoos, chip numbers, etc. The animal Id search will resolve the animals by these aliases and provide feedback in the Id Resolution section when an alias is used to find an animal Id. ID matching is case-insensitive, so searching for "id123", "ID123", or "Id123" will all match the same animal. The Id Resolution section will only appear when there are aliases or Ids not found in the search field. The Id Resolution section will have two sections, "Resolved" for the Ids found as they are entered or Ids found by alias lookup; and a "Not Found" section for Ids that don't resolve.   
+4. Filter Actions: The interface provides three action buttons: "Search By Ids", "All Animals", and "All Alive at Center".
+   1. Search By Ids: Triggers ID Search mode with the IDs entered in the textarea. The textarea is always visible for entering animal IDs.
+   2. All Animals: No filters applied. All current and historical animals will be included. Clears any previously entered IDs.
+   3. All Alive at Center: Applies the "Id/Demographics/calculated_status = 'Alive'" filter. Otherwise no filters applied. Clears any previously entered IDs.  
+5. All reports displayed in tabs: Single animal reports should already be tested in the previous story for Participant View. Many of these reports have a different view for multiple animals over a certain limit. These can go from a more detailed JS report for 1-5 animals to more of a grid view if more animals are selected in the filter. The multiple animal reports in particular will need to be tested and ensure all necessary data is being passed to the reports.  
+6. Metrics: Add metrics to determine which filters and which reports are being used.
+
+# Detailed Developer Design
+
+*What are the implementation details?*  
+*Think about the complexity of the code in the affected area(s) as this will impact tasks & their estimates.*
+
+## Overview
+
+This feature implements a React-based Animal History page with Search By Id functionality. The implementation extends the existing `ParticipantReports` component and `TabbedReportPanel` infrastructure to support single and multi-animal search with alias resolution.
+
+### Component Architecture
+
+```
+AnimalHistoryPage.tsx
+├── SearchByIdPanel (new component)
+│   ├── IdInputArea (always visible except URL Params mode)
+│   │   ├── Label: "Enter Animal IDs"
+│   │   └── Textarea (for single/multi ID entry)
+│   ├── Validation Error Display (conditional - shown when validation fails)
+│   ├── FilterToggleButtons (always visible except URL Params mode)
+│   │   ├── Search By Ids button (triggers ID Search, shows "Searching..." during resolution)
+│   │   ├── All Animals button (clears filters, shows all animals)
+│   │   └── All Alive at Center button (filters by Id/Demographics/calculated_status = 'Alive')
+│   ├── IdResolutionFeedback (always visible - shows feedback when aliases resolved or IDs not found)
+│   │   ├── ResolvedIdsList
+│   │   └── NotFoundIdsList
+│   └── URLParamsMode (conditional - only for shared/bookmarked links)
+│       ├── Read-only summary
+│       └── Modify Search button
+└── ParticipantReports.tsx (existing)
+    └── TabbedReportPanel.tsx (existing)
+        ├── Category tabs (primary navigation)
+        ├── Report tabs (secondary navigation)
+        └── Report renderers (JSReportWrapper, QueryReportWrapper, OtherReportWrapper)
+```
+
+### Styling Architecture
+
+All inline styles have been refactored to SCSS modules located in `labkey-ui-ehr/src/theme/`:
+
+**SCSS Files:**
+- `SearchByIdPanel.scss` - Styles for search panel, buttons, input fields, validation errors
+- `IdResolutionFeedback.scss` - Styles for ID resolution feedback component
+- `ParticipantReports.scss` - Styles for filter error messages
+- `TabbedReportPanel.scss` - Styles for report tabs, empty state placeholder
+- `OtherReportWrapper.scss` - Styles for other report wrapper component
+- `index.scss` - Main entry point that imports all component styles
+
+**Benefits:**
+- Centralized styling makes maintenance and theming easier
+- Improved performance by leveraging CSS classes instead of inline styles
+- Better code organization and separation of concerns
+- Easier to apply consistent styling across components
+- **Robust selectors:** All layout-dependent selectors (like `nth-child`) have been replaced with semantic class-based selectors for better maintainability and resilience to layout changes
+
+**CSS Classes:**
+Components now use semantic CSS classes that map to their functionality:
+- `.search-by-id-panel` - Main panel container
+- `.panel-container` - Input section wrapper
+- `.button-container` - Button group wrapper
+- `.search-button` - ID search button with `.active` and `.inactive` states
+- `.filter-button` - Filter buttons (All Animals, Alive at Center)
+  - `.all-animals` - Specific class for All Animals button
+  - `.alive-at-center` - Specific class for Alive at Center button
+- `.id-resolution-feedback` - Feedback component container
+- `.filter-not-supported-error` - Error message styling
+- `.empty-state-placeholder` - Empty state message
+
+**Selector Architecture:**
+All button styles use semantic class combinations instead of position-based selectors:
+- Search button: `.search-button.active` (blue), `.search-button.inactive` (gray)
+- All Animals button: `.filter-button.all-animals.active` (green), `.filter-button.all-animals.inactive` (gray)
+- Alive at Center button: `.filter-button.alive-at-center.active` (teal), `.filter-button.alive-at-center.inactive` (gray)
+
+This approach ensures styles remain stable even if button order changes in the DOM.
+
+### Component Modularity
+
+**ReportTab Component Extraction:**
+
+The `ReportTab` component has been extracted from `TabbedReportPanel.tsx` into its own file for better modularity and maintainability:
+
+**Location:** `labkey-ui-ehr/src/ParticipantHistory/TabbedReportPanel/ReportTab.tsx`
+
+**Benefits:**
+- Improved code organization with single-responsibility principle
+- Easier to test the ReportTab component in isolation
+- Better separation of concerns between tab management and report panel orchestration
+- Reduced file size and complexity of TabbedReportPanel.tsx
+- Dedicated test file for ReportTab-specific behavior
+
+**Exports:**
+- `ReportTab` component
+- `ReportConfig` interface
+- `FilterArray` interface
+- `QueryWebPartConfig` interface
+
+**Import Pattern:**
+All components that need these types now import directly from `ReportTab.tsx`:
+```typescript
+import { ReportConfig, QueryWebPartConfig } from './ReportTab';
+```
+
+This eliminates the need for re-exports and creates a clearer dependency structure where:
+- `ReportTab.tsx` is the single source of truth for shared types
+- `TabbedReportPanel.tsx` imports only what it needs from ReportTab
+- Report wrapper components (JSReportWrapper, QueryReportWrapper, OtherReportWrapper) import types from ReportTab
+- Test files import types directly from ReportTab
+
+**Test Coverage:**
+- `ReportTab.test.tsx` - 16 unit tests covering ExtJS integration, lifecycle, props, and filter logic
+- Test coverage: 100% statements, 97.14% branches, 100% functions
+
+### Type System
+
+**TypeScript Type Definitions:**
+
+The codebase uses strongly-typed interfaces for all configuration objects, improving type safety and developer experience:
+
+**ExtReportTab** - Extended ExtJS Container interface:
+```typescript
+export interface ExtReportTab {
+    // ExtJS Container base properties
+    isDestroyed?: boolean;
+    renderTo?: HTMLElement;
+
+    // ExtJS Container methods
+    add: (config: any) => void;
+    removeAll: () => void;
+    destroy: () => void;
+
+    // Custom properties added to tab
+    report: ReportConfig;
+    filters: any;
+
+    // Custom methods added to tab
+    getFilterArray: () => FilterArray;
+    getQWPConfig: () => QueryWebPartConfig;
+}
+```
+
+**JSReportPanel** - Panel object interface for JavaScript report functions:
+```typescript
+export interface JSReportPanel {
+    getFilterArray: () => FilterArray;
+    getQWPConfig: () => QueryWebPartConfig;
+    getTitleSuffix: () => string;
+    resolveSubjectsFromHousing: (
+        tab: ExtReportTab,
+        callback: (subjects: string[], tab: ExtReportTab) => void,
+        scope?: any
+    ) => void;
+}
+```
+
+This interface defines the contract for the panel object passed to legacy JavaScript report functions, providing access to:
+- Filter data via `getFilterArray()`
+- Query configuration via `getQWPConfig()`
+- Formatted subject titles via `getTitleSuffix()`
+- Housing location resolution via `resolveSubjectsFromHousing()`
+
+**Test Coverage for Report Wrappers:**
+
+All three report wrapper components now have comprehensive test suites:
+
+- `JSReportWrapper.test.tsx` - 17 unit tests covering function resolution, panel methods, error handling, and cleanup
+  - Coverage improved from 39.43% to 95.77% statements
+
+- `OtherReportWrapper.test.tsx` - 20 unit tests covering LABKEY.WebPart integration, filter handling, title suffix generation, and error scenarios
+  - Coverage: 100% statements, 89.47% branches, 100% functions
+  - Tests unique ID generation, containerPath, viewName, and filter parameter serialization
+
+- `QueryReportWrapper.test.tsx` - 18 unit tests covering ExtJS ldk-querycmp integration, query configuration, lifecycle management, and server context
+  - Coverage: 100% statements, 100% branches, 100% functions
+  - Tests component cleanup, error handling, and dependency tracking
+
+**FilterArray** - Standardized filter structure:
+```typescript
+export interface FilterArray {
+    nonRemovable: Filter.IFilter[];  // Filters from @labkey/api
+    removable: Filter.IFilter[];      // Filters from @labkey/api
+}
+```
+
+**QueryWebPartConfig** - Query WebPart configuration:
+```typescript
+export interface QueryWebPartConfig {
+    // Core properties
+    partName?: string;
+    schemaName?: string;
+    queryName?: string;
+    viewName?: string;
+    title?: string;
+
+    // Filter properties (from @labkey/api)
+    filters?: Filter.IFilter[];
+    removeableFilters?: Filter.IFilter[];
+
+    // Display options
+    showInsertNewButton?: boolean;
+    showDeleteButton?: boolean;
+    showDetailsColumn?: boolean;
+    showUpdateColumn?: boolean;
+    showRecordSelectors?: boolean;
+    allowChooseQuery?: boolean;
+    allowChooseView?: boolean;
+    allowHeaderLock?: boolean;
+
+    // Layout properties
+    frame?: string;
+    buttonBarPosition?: string;
+    linkTarget?: string;
+    renderTo?: string;
+
+    // Callbacks
+    success?: () => void;
+    failure?: (error: any) => void;
+
+    // Additional properties
+    tab?: any;  // ExtJS tab object
+    containerPath?: string;
+    timeout?: number;
+    suppressRenderErrors?: boolean;
+    partConfig?: any;
+    [key: string]: any;  // Allow additional report config properties
+}
+```
+
+**Benefits:**
+- Compile-time type checking prevents runtime errors
+- IntelliSense support in IDEs for better developer experience
+- Self-documenting code through explicit type definitions
+- Easier refactoring with TypeScript's type safety
+- Standardized interface shared across QueryReportWrapper, OtherReportWrapper, and TabbedReportPanel
+
+### React Component Display Names
+
+All exported React components now have explicit `displayName` properties for improved debugging and error stack traces:
+
+**Components with Display Names:**
+- `JSReportWrapper` - Wrapper for JavaScript-based report functions
+- `OtherReportWrapper` - Wrapper for LABKEY.WebPart report integration
+- `QueryReportWrapper` - Wrapper for ExtJS ldk-querycmp integration
+- `TabbedReportPanel` - Main tabbed panel component
+- `ParticipantReports` - Top-level participant reports container
+
+**Pattern Used:**
+```typescript
+const ComponentNameComponent: FC<Props> = ({ props }) => {
+    // Component logic
+};
+ComponentNameComponent.displayName = 'ComponentName';
+export const ComponentName = memo(ComponentNameComponent);
+```
+
+**Benefits:**
+- Better debugging experience in React DevTools
+- Clearer error messages with component names in stack traces
+- Improved component identification during development
+- Compliance with ESLint react/display-name rule
+
+### Optional Chaining Improvements
+
+Optional chaining (`?.`) has been implemented throughout the codebase to replace verbose null checks, making the code more concise and readable:
+
+**JSReportWrapper.tsx:**
+- `tab?.filters` - Safe access to tab filters (line 152)
+- `ns?.[handlerName]` - Safe property access on namespace object (line 46)
+
+**OtherReportWrapper.tsx:**
+- `tab?.filters` - Safe access to tab filters (line 32)
+- `subjects?.length` - Safe length check on subjects array (line 33)
+- `filters?.length` - Safe length check on filters array (line 47)
+
+**TabbedReportPanel.tsx:**
+- `categoryReports?.length` - Safe length check on category reports (line 146)
+- `activeCategoryReports?.length` - Safe length check in JSX rendering (line 179)
+
+**Benefits:**
+- More concise code compared to `variable && variable.property` patterns
+- Prevents runtime errors from accessing properties on null/undefined
+- Improved readability and maintainability
+- Modern TypeScript/JavaScript best practice
+
+## New Components
+
+### 1. SearchByIdPanel
+
+**Location:** `labkey-ui-ehr/src/ParticipantHistory/SearchByIdPanel/SearchByIdPanel.tsx`
+
+**Props Interface:**
+```typescript
+interface SearchByIdPanelProps {
+    onFilterChange: (filterType: 'idSearch' | 'all' | 'aliveAtCenter' | 'urlParams', subjects?: string[]) => void;
+    initialSubjects?: string[];
+    initialFilterType?: 'idSearch' | 'all' | 'aliveAtCenter' | 'urlParams';
+    activeReportSupportsNonIdFilters: boolean; // From ehr.reports.supportsNonIdFilters field
+}
+```
+
+**State:**
+- `inputValue: string` - Raw text from textarea
+- `filterType: 'idSearch' | 'all' | 'aliveAtCenter' | 'urlParams'` - Current filter selection
+- `isResolving: boolean` - Loading state during ID resolution
+- `resolutionResult: IdResolutionResult` - Results of alias resolution
+- `validationError: string | null` - Error message if validation fails (e.g., exceeds 100 ID limit)
+
+**Behavior:**
+- **ID Input Area (Always Visible):**
+  - Textarea is always visible, regardless of filter mode
+  - Accepts single or multiple animal IDs
+  - Parses input using separators: newlines (`\n`), tabs (`\t`), commas (`,`), semicolons (`;`)
+  - Handles IDs with letters, numbers, special characters, and spaces in names
+  - Validates that no more than 100 unique IDs are entered (after parsing and de-duplication)
+  - Displays validation error if limit exceeded; prevents calling `onFilterChange` until resolved
+  - Search By Ids button shows "Searching..." text while ID resolution is in progress
+  - Search By Ids button is disabled only during resolution (not for validation errors)
+
+- **Search By Ids Button (Triggers ID Search Mode):**
+  - When clicked, immediately sets `filterType` to 'idSearch' (making button blue and other buttons gray), then performs ID resolution
+  - This means the button turns blue and becomes the active mode even if validation errors occur
+  - Button text changes to "Searching..." during resolution
+  - Button is disabled only while resolving (not when validation errors exist)
+  - Button styling: Shows blue (#0066cc) when active (filterType === 'idSearch'), gray (#6c757d) when inactive, disabled gray (#ccc) when resolving
+  - If validation fails (e.g., no IDs or >100 IDs), the button stays enabled and blue, but ID resolution doesn't proceed
+  - Updates `IdResolutionFeedback` component with resolution results
+  - Calls `onFilterChange('idSearch', resolvedSubjects)` with resolved subjects after successful resolution
+
+- **All Animals Button:**
+  - When clicked, activates All Animals mode
+  - Clears any entered IDs in the textarea
+  - Clears any validation errors that were displayed
+  - Reports show all animals (no filters on IDs or status)
+  - Button styling: Shows green (#28a745) when active (filterType === 'all'), gray (#6c757d) when inactive
+  - Calls `onFilterChange('all', undefined)` immediately when button clicked
+
+- **All Alive at Center Button:**
+  - When clicked, activates Alive at Center mode
+  - Button disabled if `activeReportSupportsNonIdFilters === false`
+  - Clears any entered IDs in the textarea
+  - Clears any validation errors that were displayed
+  - Reports filter on `Id/Demographics/calculated_status = 'Alive'` (lookup to demographics table)
+  - Button styling: Shows cyan (#17a2b8) when active (filterType === 'aliveAtCenter'), gray (#6c757d) when inactive, disabled gray (#ccc) when report doesn't support non-ID filters
+  - Calls `onFilterChange('aliveAtCenter', undefined)` immediately when button clicked
+- **URL Params Mode (`filterType === 'urlParams'`):**
+  - Activated when URL contains `readOnly=true` parameter (for shared/bookmarked links)
+  - **Hides entire filter section** (textarea and all buttons)
+  - Shows read-only summary: "Viewing {count} animal(s): {subject1}, {subject2}, ..."
+  - Shows "Modify Search" button that switches to ID Search mode with current subjects pre-populated
+  - Reports filter by URL subjects without requiring ID resolution
+  - No ID limit applies (URL-provided subjects are assumed already validated/resolved)
+
+**IdResolutionFeedback:**
+- Always rendered (not conditionally based on filter mode)
+- Component controls its own visibility via `isVisible` prop
+- Shows feedback when aliases are resolved or IDs are not found
+- Remains visible even when switching between filter modes (since textarea is always visible)
+
+**Internal Structure:**
+- `SearchByIdPanel` internally manages `IdResolutionFeedback` component
+- Resolution results are managed as internal state, not passed to parent
+- Parent component (`ParticipantReports`) only receives final resolved subject IDs
+- Textarea and filter buttons are always visible except in URL Params mode
+- URL Params mode provides a read-only view for shared/bookmarked links
+
+### 2. IdResolutionFeedback
+
+**Location:** `labkey-ui-ehr/src/ParticipantHistory/SearchByIdPanel/IdResolutionFeedback.tsx`
+
+**Props Interface:**
+```typescript
+interface IdResolutionResult {
+    resolved: Array<{
+        inputId: string;
+        resolvedId: string;
+        resolvedBy: 'direct' | 'alias';
+        aliasType?: string; // e.g., 'tattoo', 'chip', 'nickname'
+    }>;
+    notFound: string[];
+}
+
+interface IdResolutionFeedbackProps {
+    resolutionResult: IdResolutionResult;
+    isVisible: boolean; // Only show when there are aliases or not-found IDs
+}
+```
+
+**Display Logic:**
+- Component only renders when `isVisible === true` (caller determines visibility using: `resolutionResult.resolved.some(r => r.resolvedBy === 'alias') || resolutionResult.notFound.length > 0`)
+- Returns `null` when `isVisible === false`
+- "Resolved" section (shown when `resolved.length > 0`):
+  - Direct matches displayed as: `ID123` (just the resolved ID)
+  - Alias matches displayed as: `TATTOO_001 → ID123 (tattoo)` (inputId → resolvedId (aliasType))
+  - Direct matches listed first, followed by alias matches
+  - Uses semantic `<ul>` and `<li>` markup for accessibility
+- "Not Found" section (shown when `notFound.length > 0`):
+  - Lists unresolved IDs that couldn't be found directly or via alias
+  - Uses semantic `<ul>` and `<li>` markup for accessibility
+- Uses proper heading hierarchy: `<h2>` for "ID Resolution", `<h3>` for section headings
+
+## Modified Components
+
+### 1. ParticipantReports.tsx
+
+**Changes Required:**
+- Add `SearchByIdPanel` above `TabbedReportPanel`
+- Manage `subjects` and `filterType` state locally instead of only from URL
+- Update URL hash when filter changes
+- Pass filter information to `TabbedReportPanel` via `filters` prop
+- Provide `activeReportSupportsNonIdFilters` to `SearchByIdPanel` from active report metadata
+- `SearchByIdPanel` internally manages ID resolution and displays `IdResolutionFeedback` (not managed by parent)
+
+**Updated Structure:**
+```typescript
+export const ParticipantReports: FC = memo(() => {
+    const urlFilters = useMemo(() => getFiltersFromUrl(), []);
+    const [subjects, setSubjects] = useState<string[]>(urlFilters.subjects || []);
+
+    // Determine initial filter type based on URL parameters
+    const initialFilterType = useMemo(() => {
+        if (urlFilters.readOnly && urlFilters.subjects?.length > 0) {
+            return 'urlParams'; // Read-only mode for shared links
+        }
+        return urlFilters.filterType || 'idSearch';
+    }, [urlFilters]);
+
+    const [filterType, setFilterType] = useState<'idSearch' | 'all' | 'aliveAtCenter' | 'urlParams'>(initialFilterType);
+    const [activeReport, setActiveReport] = useState(urlFilters.activeReport);
+    const [showReport, setShowReport] = useState<boolean>(urlFilters.showReport ?? false);
+
+    // Query active report metadata to get supportsNonIdFilters field
+    // Uses LABKEY.Query.selectRows to query ehr.reports table
+    // Filter by reportname field (activeReport contains the report name from TabbedReportPanel)
+    // Stores result in state (activeReportSupportsNonIdFilters)
+    // Defaults to true if query fails or no active report
+
+    // Override filter to 'all' when aliveAtCenter not supported
+    // Compute effectiveFilterType: if filterType is 'aliveAtCenter' and
+    // activeReportSupportsNonIdFilters is false, override to 'all'
+    // Display error message when override occurs
+    // Pass effectiveFilterType to TabbedReportPanel filters
+
+    const handleFilterChange = useCallback((
+        newFilterType: 'idSearch' | 'all' | 'aliveAtCenter' | 'urlParams',
+        newSubjects?: string[]
+    ) => {
+        setFilterType(newFilterType);
+        setSubjects(newSubjects || []);
+
+        // Determine if report should be shown
+        // Show report for 'all' and 'aliveAtCenter' modes always
+        // Show report for 'idSearch' and 'urlParams' only when subjects exist
+        const shouldShowReport =
+            newFilterType === 'all' ||
+            newFilterType === 'aliveAtCenter' ||
+            ((newFilterType === 'idSearch' || newFilterType === 'urlParams') &&
+                (newSubjects?.length ?? 0) > 0);
+        setShowReport(shouldShowReport);
+
+        // When switching from urlParams to idSearch (via "Modify Search"), remove readOnly parameter
+        const isLeavingReadOnly = filterType === 'urlParams' && newFilterType !== 'urlParams';
+        const readOnly = newFilterType === 'urlParams' && !isLeavingReadOnly;
+        updateUrlHash(newFilterType, newSubjects, readOnly, shouldShowReport);
+    }, [filterType]);
+
+    const handleTabChange = useCallback((reportId: string) => {
+        setActiveReport(reportId);
+        // Update URL hash with new activeReport
+        updateUrlHash(filterType, subjects, filterType === 'urlParams', showReport);
+    }, [filterType, subjects, showReport]);
+
+    const filters = useMemo(() => ({
+        filterType,
+        subjects: (filterType === 'idSearch' || filterType === 'urlParams') ? subjects : undefined,
+    }), [filterType, subjects]);
+
+    return (
+        <div>
+            <SearchByIdPanel
+                onFilterChange={handleFilterChange}
+                initialSubjects={subjects}
+                initialFilterType={filterType}
+                activeReportSupportsNonIdFilters={activeReportSupportsNonIdFilters}
+            />
+            <TabbedReportPanel
+                activeReport={activeReport}
+                filters={filters}
+                onTabChange={handleTabChange}
+                reportNamespace="EHR.reports"
+                reportsQuery="reports"
+                reportsSchema="ehr"
+                showReport={showReport}
+            />
+        </div>
+    );
+});
+```
+
+**Key Points:**
+- `ParticipantReports` no longer manages `resolutionResult` state
+- `IdResolutionFeedback` is rendered inside `SearchByIdPanel`, not here
+- Simplified state management - parent only tracks final resolved subjects, not resolution details
+- URL Params mode (`readOnly=true`) enables read-only view for shared/bookmarked links
+- "Modify Search" button in URL Params mode removes `readOnly` parameter and switches to ID Search mode
+- `showReport` state controls report visibility:
+  - Defaults to `false` on initial page load (shows placeholder message)
+  - Set to `true` for 'all' and 'aliveAtCenter' modes always
+  - Set to `true` for 'idSearch' and 'urlParams' modes only when subjects exist
+  - Synced to URL hash (showReport:1 when true, omitted when false)
+
+### 2. AnimalHistoryPage.tsx
+
+**Changes Required:**
+- Remove placeholder text "This is Animal History"
+- Component serves as entry point wrapping `ParticipantReports`
+
+## API Integration
+
+### Id Resolution Service
+
+**New File:** `labkey-ui-ehr/src/ParticipantHistory/services/idResolutionService.ts`
+
+```typescript
+interface ResolveIdsParams {
+    inputIds: string[];
+}
+
+export async function resolveAnimalIds(params: ResolveIdsParams): Promise<IdResolutionResult> {
+    // Step 1: Query study.demographics for direct ID matches
+    // Step 2: Query study.alias for alias matches on unresolved IDs
+    // Step 3: Return consolidated results
+}
+```
+
+**Database Queries:**
+
+The two-query approach correctly handles multiple aliases per animal ID by filtering to only aliases that match the user's input. The service uses pre-defined LabKey queries in `server/modules/ehrModules/ehr/resources/queries/study/` that provide case-insensitive matching via computed lowercase columns.
+
+1. **Direct ID Lookup:**
+
+Query: `study.directIdMatches`
+
+This query is defined in `directIdMatches.sql` and returns:
+```sql
+SELECT
+    Id as resolvedId,
+    Id as inputId,
+    'direct' as resolvedBy,
+    NULL as aliasType,
+    LOWER(Id) as lowerIdForMatching
+FROM study.demographics
+```
+
+Filter on `lowerIdForMatching` column using lowercase input IDs:
+```typescript
+Filter.create('lowerIdForMatching', lowercaseInputIds, Filter.Types.IN)
+```
+
+2. **Alias Lookup (for unresolved IDs only):**
+
+Query: `study.aliasIdMatches`
+
+This query is defined in `aliasIdMatches.sql` and returns:
+```sql
+SELECT
+    a.Id as resolvedId,
+    a.alias as inputId,
+    'alias' as resolvedBy,
+    a.aliasType,
+    LOWER(a.alias) as lowerAliasForMatching
+FROM study.alias a
+INNER JOIN study.demographics d ON a.Id = d.Id
+```
+
+Filter on `lowerAliasForMatching` column using lowercase unresolved input IDs:
+```typescript
+Filter.create('lowerAliasForMatching', lowercaseUnresolvedInputIds, Filter.Types.IN)
+```
+
+**Key Points:**
+- Uses pre-defined LabKey query definitions (`study.directIdMatches` and `study.aliasIdMatches`) rather than raw SQL
+- Case-insensitive matching via computed `lowerIdForMatching` and `lowerAliasForMatching` columns
+- Query 2 only runs with IDs not found in Query 1, avoiding unnecessary lookups
+- The filter on lowercase columns ensures we only return IDs/aliases that match the user's input (case-insensitive)
+- Each query returns the input-to-resolved-ID mapping needed for the IdResolutionFeedback display
+- The application layer de-duplicates resolved IDs when passing to reports (multiple inputs may resolve to the same animal ID)
+- Using pre-defined queries ensures consistency across the EHR module and simplifies maintenance
+
+## URL Hash Format
+
+The URL hash format follows the existing pattern in `ParticipantReports.tsx`:
+
+**Initial Page Load (no filters active):**
+```
+#filterType:idSearch
+```
+(No showReport parameter - reports hidden, placeholder message shown)
+
+**ID Search mode (with subjects):**
+```
+#subjects:{id1};{id2};{id3}&filterType:idSearch&activeReport:{reportId}&showReport:1
+```
+
+**Show All mode:**
+```
+#filterType:all&activeReport:{reportId}&showReport:1
+```
+
+**Alive at Center mode:**
+```
+#filterType:aliveAtCenter&activeReport:{reportId}&showReport:1
+```
+
+**URL Params mode (shared/bookmarked link - read-only):**
+```
+#subjects:{id1};{id2};{id3}&readOnly:true&activeReport:{reportId}&showReport:1
+```
+
+**Parameters:**
+- `subjects` - Semicolon-separated list of resolved animal IDs (present for `idSearch` and `urlParams` modes)
+- `filterType` - `idSearch`, `all`, or `aliveAtCenter` (not used for `urlParams` mode)
+- `readOnly` - `true` to enable URL Params mode (read-only view with no search UI)
+- `activeReport` - Currently selected report ID
+- `showReport` - Whether to show report content (1 = true). Omitted when reports should not be displayed (initial page load, ID Search with no subjects)
+
+**URL Params Mode Notes:**
+- When `readOnly=true` is present with subjects, automatically activates URL Params mode
+- Used for sharing specific animal results or bookmarking
+- Subjects are assumed to be already resolved/validated (no ID resolution performed)
+- "Modify Search" button removes `readOnly` parameter and switches to ID Search mode
+
+## Report Schema Changes
+
+### New Field in ehr.reports Table
+
+A new boolean field must be added to the `ehr.reports` table to indicate report support for non-ID filters:
+
+**Field:** `supportsNonIdFilters` (boolean, default: false)
+
+**Purpose:** Indicates whether a report can handle the "Alive, at Center" filter mode which filters by status without requiring specific subject IDs.
+
+**Usage:**
+- Reports with `supportsNonIdFilters = true` can filter by `Id/Demographics/calculated_status = 'Alive'` across all animals
+- Reports with `supportsNonIdFilters = false` will have only the "Alive, at Center" button disabled
+- All reports support "All Records" (no filters) and "ID Search" (specific IDs) modes regardless of this field
+- Most legacy single/multi-animal reports will default to `false` and require migration to support status filtering
+
+## Filter Integration with TabbedReportPanel
+
+The `TabbedReportPanel` needs updates to handle four filter modes:
+
+**Updated `ReportTab` component:**
+```typescript
+newTab.getFilterArray = () => {
+    const filterArray = { removable: [], nonRemovable: [] };
+    const subjectFieldName = report.subjectFieldName || 'Id';
+
+    // ID Search mode: Filter by specific subject IDs
+    if (filters && filters.filterType === 'idSearch' && filters.subjects && filters.subjects.length) {
+        const subjects = filters.subjects;
+        if (subjects.length === 1) {
+            filterArray.nonRemovable.push(Filter.create(subjectFieldName, subjects[0], Filter.Types.EQUAL));
+        } else {
+            filterArray.nonRemovable.push(
+                Filter.create(subjectFieldName, subjects.join(';'), Filter.Types.EQUALS_ONE_OF)
+            );
+        }
+    }
+
+    // URL Params mode: Filter by URL-provided subject IDs (same as ID Search)
+    if (filters && filters.filterType === 'urlParams' && filters.subjects && filters.subjects.length) {
+        const subjects = filters.subjects;
+        if (subjects.length === 1) {
+            filterArray.nonRemovable.push(Filter.create(subjectFieldName, subjects[0], Filter.Types.EQUAL));
+        } else {
+            filterArray.nonRemovable.push(
+                Filter.create(subjectFieldName, subjects.join(';'), Filter.Types.EQUALS_ONE_OF)
+            );
+        }
+    }
+
+    // Alive at Center mode: Filter by calculated_status
+    if (filters && filters.filterType === 'aliveAtCenter') {
+        filterArray.nonRemovable.push(
+            Filter.create('Id/Demographics/calculated_status', 'Alive', Filter.Types.EQUAL)
+        );
+    }
+
+    // Show All mode: No filters applied (filterType === 'all')
+
+    return filterArray;
+};
+```
+
+**Key Points:**
+- ID Search mode applies subject ID filters after user-initiated resolution
+- URL Params mode applies subject ID filters from URL without resolution
+- Alive at Center mode applies `Id/Demographics/calculated_status = 'Alive'` filter (lookup to demographics)
+- All Animals mode applies no filters (shows all animals)
+- The 100 ID limit only applies to ID Search mode
+- Non-ID filter modes (all, aliveAtCenter, urlParams) have no ID limits and don't go through ID resolution
+
+## Empty State Placeholder
+
+When `showReport` prop is false (initial page load, ID Search with no subjects), TabbedReportPanel displays a centered placeholder message instead of report content:
+
+```tsx
+<div style={{
+    display: 'flex',
+    justifyContent: 'center',
+    alignItems: 'center',
+    minHeight: '300px',
+    padding: '40px',
+    color: '#666',
+    fontSize: '16px',
+    fontWeight: '500',
+}}>
+    Select Filter to View Reports
+</div>
+```
+
+**When Placeholder is Shown:**
+- Initial page load (no URL hash or filterType:idSearch with no subjects)
+- ID Search mode active but no subjects entered
+- User cleared search without selecting another filter mode
+
+**When Reports are Shown:**
+- User clicks "Search By Ids" with valid subjects
+- User clicks "All Animals"
+- User clicks "All Alive at Center"
+- URL contains `showReport:1` parameter (bookmarked/shared links)
+
+## Edge Cases
+
+### ID Search Mode Only:
+
+1. **Empty Input:** Display validation message; do not call API; pass empty array to reports to show no records
+2. **Whitespace-only Input:** Treat as empty input after trimming; display validation message; pass empty array to reports to show no records
+3. **Duplicate IDs:** De-duplicate before resolution; show each unique ID once in results
+4. **Mixed Valid/Invalid IDs:** Resolve valid IDs; show invalid in "Not Found" section
+5. **All IDs Not Found:** Display "Not Found" section only; reports panel shows no data message
+6. **Alias Resolves to Same ID:** If multiple input values resolve to the same animal ID, show all in "Resolved" section but pass de-duplicated list to reports
+7. **Special Characters in IDs:** Support IDs with hyphens, underscores, and other special characters
+8. **Case Sensitivity:** ID matching is case-insensitive for both direct ID and alias lookups, implemented using LabKey SQL's `lower()` function
+9. **ID Limit Exceeded:** Hard limit of 100 unique IDs (after parsing and de-duplication). Display clear validation error: "Maximum of 100 animal IDs allowed. You entered {count} IDs." Button remains enabled but ID resolution will not proceed until input is reduced. Pass empty array to reports to show no records.
+
+### All Filter Modes:
+
+10. **Report Doesn't Support Non-ID Filters:** If `activeReportSupportsNonIdFilters === false`, disable only the "All Alive at Center" button. "ID Search" and "All Animals" modes remain available.
+11. **Switching Filter Modes:** When switching from ID Search to All Animals or All Alive at Center, clear the ID input textarea, resolution results, and any validation errors. The textarea remains visible across all modes (except URL Params).
+12. **Search By Ids with Validation Error:** When "Search By Ids" is clicked with a validation error (e.g., no IDs entered or >100 IDs), the button immediately sets the filter mode to ID Search (turns blue, grays out other buttons) but does not proceed with ID resolution. The validation error remains displayed until resolved. An empty array is passed to reports to show no records.
+13. **No Active Report Selected:** Default behavior - may need to handle gracefully or default to first available report.
+
+### URL Params Mode Only:
+
+14. **No Subjects in URL:** If `readOnly=true` but no subjects parameter, default to "All Animals" mode and ignore `readOnly`.
+15. **Invalid Subject IDs:** URL subjects are assumed valid; if reports show no data, display message indicating subjects may not exist or user lacks permissions.
+16. **Modify Search Button:** Clicking "Modify Search" switches to ID Search mode with subjects pre-populated in textarea, removes `readOnly` parameter from URL.
+17. **Direct URL Navigation:** When user shares URL with `readOnly=true`, recipient sees read-only view immediately on page load without search UI.
+18. **URL with Both filterType and readOnly:** If URL has `readOnly=true`, ignore `filterType` parameter and use URL Params mode.
+19. **Excessive Subject Count in URL:** No limit enforced on URL Params mode subjects (assumed to be curated/valid from previous search); browser URL length limits (~2,000 chars) are the only practical constraint.
+
+## Permissions
+
+- **Required Permission:** Folder Read Permission
+- **Dataset Permissions:** Read permission on `study.demographics` and `study.alias` datasets
+- Reports inherit existing dataset-level permissions through `TabbedReportPanel`
+
+## Metrics
+
+Add tracking for:
+1. **Filter Usage:**
+   - `animalHistory.filter.idSearch` - ID Search mode used (include count of IDs)
+   - `animalHistory.filter.idSearch.single` - Single ID search performed
+   - `animalHistory.filter.idSearch.multi` - Multi ID search performed (include count)
+   - `animalHistory.filter.all` - "Show All" filter selected
+   - `animalHistory.filter.aliveAtCenter` - "Alive, at Center" filter selected
+
+2. **Resolution Stats (ID Search mode only):**
+   - `animalHistory.search.aliasResolved` - Count of IDs resolved via alias
+   - `animalHistory.search.notFound` - Count of IDs not found
+
+3. **Report Usage:**
+   - Existing report tab tracking in `TabbedReportPanel` via `onTabChange`
+   - Track which reports are viewed with each filter mode

+   - Test `readOnly` parameter removed when switching from URL Params to ID Search mode
+   - Test navigation/bookmark scenarios for each mode
+
+### Manual Test Scenarios
+
+**Initial Page Load:**
+1. Navigate to Animal History page (no URL hash)
+   - Verify ID Search mode is active (button highlighted)
+   - Verify empty textarea is shown
+   - Verify placeholder message displayed: "Select Filter to View Reports"
+   - Verify no reports are rendered
+   - Verify all filter buttons are visible and enabled
+
+**ID Search Mode:**
+2. Single animal ID search (direct match)
+3. Single animal ID search (alias match)
+4. Multiple animal IDs (all direct matches)
+5. Multiple animal IDs (mixed direct and alias)
+6. Multiple animal IDs (some not found)
+7. Enter exactly 100 IDs (should succeed)
+8. Enter 101+ IDs (should show validation error and prevent search)
+9. Verify report data matches selected animals for ID Search
+
+#### Show All Mode
+
+10. Click "Show All" button and verify reports show all animals
+11. Verify ID Search section (textarea + Search By Ids button) is hidden
+12. Verify no ID limit applies in Show All mode
+13. Verify URL bookmarking works for Show All mode
+
+#### Alive, at Center Mode
+
+14. Click "Alive, at Center" on a report with `supportsNonIdFilters = true`
+15. Verify reports show only animals with `Id/Demographics/calculated_status = 'Alive'`
+16. Verify ID Search section (textarea + Search By Ids button) is hidden
+17. Verify "Alive, at Center" button is disabled on report with `supportsNonIdFilters = false`
+18. Switch to a different report and verify button state updates based on new report's `supportsNonIdFilters` value
+
+#### URL Params Mode (Read-Only)
+
+19. Navigate to URL with `readOnly=true` and subjects parameter
+20. Verify entire filter section is hidden (no filter buttons, no ID textarea)
+21. Verify read-only summary displays subject count and IDs
+22. Verify reports are filtered by URL subjects
+23. Click "Modify Search" button and verify:
+    - Switches to ID Search mode
+    - Subjects pre-populated in textarea
+    - `readOnly` removed from URL
+    - Filter section now visible with all buttons
+24. Test URL with `readOnly=true` but no subjects (should default to Show All)
+25. Test URL with both `filterType` and `readOnly=true` (should use URL Params mode)
+
+#### Filter Mode Switching
+
+26. Switch from ID Search to Show All (verify ID Search section hidden, input cleared)
+27. Switch from ID Search to Alive, at Center (verify ID Search section hidden, input cleared)
+28. Switch from Show All to ID Search (verify ID Search section visible, empty textarea)
+29. Switch from Alive, at Center to ID Search (verify ID Search section visible, empty textarea)
+
+## Configuration Considerations
+
+- **Center-specific Alias Types:** Different centers may have different alias categories. The alias resolution should query all alias types from `study.alias` without hardcoding specific types.
+- **Demographics Status Field:** The "Alive, at Center" filter relies on `Id/Demographics/calculated_status` field (lookup to demographics table). Verify this field exists and is populated correctly across all center implementations.
+
+## What Might Go Wrong
+
+1. **Performance with Large ID Lists:** Addressed with hard limit of 100 IDs maximum for ID Search mode. This prevents slow queries while supporting typical use cases.
+2. **Performance with "All Records" Mode:** No ID limit on All Records and Alive at Center modes could cause performance issues with very large datasets. Reports need to handle pagination or lazy loading.
+3. **Alias Table Not Populated:** Some centers may not use aliases extensively. Handle gracefully with direct matches only.
+4. **Inconsistent Demographics Data:** The `calculated_status` field may have different values across centers. Document expected values.
+5. **Report Schema Migration:** Adding `supportsNonIdFilters` field to `ehr.reports` requires database migration. Existing reports default to `false`, so "Alive, at Center" will be disabled until reports are updated.
+6. **ExtJS Report Compatibility:** Some JS reports may expect specific filter formats. Test all report types with new filter structure and all three filter modes.
+7. **URL Length Limits:** Mitigated by 100 ID limit for ID Search mode. Even with maximum-length IDs, 100 subjects should stay within browser URL limits (~2,000 characters). Monitor in testing if approaching limits with long ID names.
+8. **Report Tab Changes:** When user switches between report tabs, the `activeReportSupportsNonIdFilters` value changes, which could enable/disable the "Alive, at Center" button mid-session. Ensure UI clearly indicates why button state changed.

+
+# Testing
+
+## Manual Test Plan
+
+### Related Areas
+
+* **Animal History Reports** - All existing animal history reports must function with new filter modes
+* **URL Sharing/Bookmarking** - URLs with subjects and readOnly parameter must work across sessions and users
+* **Demographics and Alias Data** - ID resolution depends on study.demographics and study.alias tables
+* **Report Metadata** - ehr.reports.supportsNonIdFilters field affects "Alive, at Center" button state
+* **Permissions** - Report access controlled by folder and dataset permissions
+* **ExtJS Reports** - Legacy JavaScript reports must receive correct filter data
+* **React Reports** - QueryReportWrapper and JSReportWrapper must handle all filter modes
+* **TabbedReportPanel** - Existing report tab navigation and filter application

+
+### Error Cases
+
+#### ID Resolution Errors
+
+* All IDs invalid/not found - verify "Not Found" section only, reports show no data (empty array passed to filters)
+* Network error during resolution - verify error message displayed, user can retry, reports show no data (empty array passed to filters)
+* Timeout during long-running alias query (e.g., 100 IDs) - verify timeout error with retry option
+* Permission denied to demographics/alias tables - verify appropriate error message
+* Malformed IDs with special characters (e.g., "###", "***") - verify treated as literal ID string, appears in "Not Found" section
+* IDs with SQL injection patterns (e.g., "'; DROP TABLE--") - verify treated as literal string, no security issue
+
+#### Validation Errors
+
+* Empty ID input - verify validation message: "Please enter at least one animal ID"
+* Whitespace-only input - verify treated as empty, validation error shown
+* 101+ IDs entered - verify limit error and disabled button
+
+#### Report Loading Errors
+
+* Report query fails - verify error message in report panel, other tabs still accessible
+* No data for selected animals - verify "No data found" message
+* Report doesn't support filter mode - verify appropriate message or disabled state
+
+#### URL/Navigation Errors
+
+* URL with `readOnly=true` but no subjects - verify defaults to All Animals mode or shows error
+* Malformed URL hash - verify defaults to ID Search mode with no subjects
+* URL with conflicting parameters (e.g., `readOnly=true` AND `filterType=all`) - verify `readOnly` takes priority, switches to urlParams mode
+* URL hash exceeds browser limit (~2000 chars with many subjects) - verify graceful degradation or error
+* Browser back/forward with filter changes - verify state maintained correctly
+
+#### Permission Errors
+
+* User lacks folder read permission - verify redirect to permission denied page
+* User lacks dataset permissions - verify reports show "permission denied" for those datasets
+* Shared URL accessed by user without permissions - verify appropriate error message

+#### Test Data Setup
+
+**IMPORTANT:** Before running these tests, implement the stub methods below. Alternatively, mark tests requiring this data as `@Ignore` until data setup is complete.
+
+Add to `EHR_AppTest` setup methods:
+
+```java
+@Override
+protected void doCreateSteps()
+{

+
+#### Test Data Requirements
+
+- Minimum 5-10 test animal IDs (use existing `MORE_ANIMAL_IDS` array)
+- For 100 ID limit test: Either generate 100 test IDs programmatically or use realistic count (e.g., 20-50) and adjust test expectations
+- At least 3 animals with aliases (tattoos, chips) for alias resolution testing - configured by `setupAliasTestData()`
+- Mix of alive and dead animals for Alive at Center testing - ensured by `ensureStatusVariety()`
+  - Define test constant: `private static final String DEAD_ANIMAL_ID = "<specific_dead_animal_id>";`
+  - Use in test 9 to verify exclusion from Alive at Center results
+- At least two test reports: one supporting non-ID filters, one not supporting - configured by `configureTestReportMetadata()`
