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.
