Social media combines intense visibility with remarkably weak public memory. A text, image or video may reach thousands of people within hours and become difficult to recover several weeks later, displaced by subsequent content, inaccessible search, deleted accounts, broken links or changes to the interface through which it originally circulated. The platform retains extensive behavioural histories for advertising, recommendation and security, yet the user often receives only rudimentary tools for navigating the intellectual record of their own participation. Publication and preservation have therefore separated. People experience posting as the placement of material into public space, while technically they are submitting it to a ranked stream whose continuity depends upon corporate databases and variable rules of display. Work on web archives shows that digital culture is not preserved merely because it was once online; meaningful access requires collection, metadata, interfaces and sustained infrastructure. VectorAfterlife concerns the trajectory that remains after the original moment of attention: whether an object can still be found, attributed, cited, exported and understood outside the interface that first accelerated it. Social networks are highly effective for announcement, reaction and redistribution, but these functions should not be confused with archival custody. Significant materials require stable copies, intelligible file names, dates, descriptive metadata and locations that do not depend entirely upon the feed. A photograph without context may survive as an image while losing the project, place and authorship that made it meaningful; a thread may be quoted widely yet become unreadable after one linked account disappears; a video may retain millions of views while its original resolution, credits or accompanying text are lost. The appropriate response is not to abandon social media or insist that every casual exchange be preserved. It is to recognise different levels of consequence. Ephemeral conversation can remain ephemeral, while work expected to support future research, cultural memory or professional continuity should be deposited elsewhere and linked into the platform rather than existing only inside it. Redundancy becomes a form of care: a public page, a repository copy, a local archive and a simple index can together resist the failure of any single system. The paradox is that societies capable of recording almost every event may leave behind a fragmented historical surface governed by what platforms found profitable to retain. The social post should therefore be understood as a temporary aperture rather than the final home of cultural material. Its speed gives work a public moment; only deliberate archival architecture gives that moment an afterlife.
