# Feature Specification: Copy Link Feature

**Feature Branch**: `006-copy-link-feature`  
**Created**: 2025-10-13  
**Status**: Draft  
**Input**: User description: "Copy Link feature. On the response and result pages display a "Copy Link" button. It must pe placed next to the session Topic and be of the secondary color. On click copy the address of the current session to the buffer. Icon: link. Animation: 'link' icon changes to green 'check' icon through dissolve and in 3 seconds changes back."

## User Scenarios & Testing *(mandatory)*

### User Story 1 - Share Session Link from Response Page (Priority: P1)

As a user on the session response page, I want to easily copy the current session's link so I can share it with others.

**Why this priority**: This is a core sharing functionality, enabling collaboration and distribution of session results, which is fundamental to the application's purpose.

**Independent Test**: Can be fully tested by navigating to a session response page, clicking the "Copy Link" button, and verifying the URL is copied to the clipboard and the animation plays correctly.

**Acceptance Scenarios**:

1.  **Given** the user is on a session's response page, **When** the page loads, **Then** a "Copy Link" button with a 'link' icon is displayed next to the session topic, styled with the secondary color.
2.  **Given** the "Copy Link" button is displayed, **When** the user clicks the button, **Then** the current session's URL is copied to the clipboard, the 'link' icon smoothly transitions to a green 'check' icon, and after 3 seconds, the 'check' icon smoothly transitions back to the 'link' icon.

### User Story 2 - Share Session Link from Result Page (Priority: P1)

As a user on the session result page, I want to easily copy the current session's link so I can share it with others.

**Why this priority**: Similar to the response page, enabling sharing from the final result page is crucial for disseminating the outcome of a session.

**Independent Test**: Can be fully tested by navigating to a session result page, clicking the "Copy Link" button, and verifying the URL is copied to the clipboard and the animation plays correctly.

**Acceptance Scenarios**:

1.  **Given** the user is on a session's result page, **When** the page loads, **Then** a "Copy Link" button with a 'link' icon is displayed next to the session topic, styled with the secondary color.
2.  **Given** the "Copy Link" button is displayed, **When** the user clicks the button, **Then** the current session's URL is copied to the clipboard, the 'link' icon smoothly transitions to a green 'check' icon, and after 3 seconds, the 'check' icon smoothly transitions back to the 'link' icon.

### Edge Cases

- What happens if the browser does not support the Clipboard API? The system should gracefully degrade, potentially by displaying a message like "Copy failed, please copy manually" or providing a text field with the URL for manual copying.
- How does the system handle cases where the session topic is not displayed or is empty? The "Copy Link" button should still appear in a consistent, logical location (e.g., near where the topic would normally be, or at a fixed position relative to the page header).

## Requirements *(mandatory)*

### Functional Requirements

- **FR-001**: The system MUST display a "Copy Link" button on the session response and result pages.
- **FR-002**: The "Copy Link" button MUST be positioned next to the session topic on both pages.
- **FR-003**: The "Copy Link" button MUST be styled with the application's secondary color.
- **FR-004**: The "Copy Link" button MUST initially display a 'link' icon.
- **FR-005**: Upon clicking the "Copy Link" button, the system MUST copy the current session's URL to the user's clipboard.
- **FR-006**: Upon successful copying, the 'link' icon MUST animate to a green 'check' icon using a dissolve effect.
- **FR-007**: After 3 seconds, the green 'check' icon MUST animate back to the 'link' icon using a dissolve effect.

### Key Entities *(include if feature involves data)*

- **Session**: Represents an active user session, identified by a unique URL. The URL is the primary data associated with the copy link feature.

## Success Criteria *(mandatory)*

### Measurable Outcomes



- **SC-001**: Users can successfully copy a session link to their clipboard from the response and result pages with a single click, 100% of the time in supported browsers.

- **SC-002**: The "Copy Link" button's visual feedback (icon change and animation) clearly indicates a successful copy operation, with the icon transition completing within 0.5 seconds and reverting within 3.5 seconds of the click.

- **SC-003**: The "Copy Link" button is consistently displayed and styled on all relevant session pages, appearing within 1 second of page load.

- **SC-004**: User feedback indicates that the copy link functionality is intuitive and easy to use, with a satisfaction rating of 4 out of 5 or higher in user surveys.



## Dependencies and Assumptions



- **Dependency**: The feature relies on the browser's native Clipboard API for copying the URL to the clipboard. If the API is not supported, a graceful degradation mechanism will be implemented as described in the Edge Cases.

- **Assumption**: A "session topic" element will be present on both the response and result pages, allowing the "Copy Link" button to be positioned adjacent to it. If not, a consistent fallback placement will be used.
