<p>We write in a world ablaze—ecological collapse, rising fascism, and genocide unfolding in real time. For the colonized, these are not new catastrophes but enduring conditions. Against this backdrop, we explore <i>postdigital feminist citizen science</i> as a set of subversive, generative practices that compost the ruins of empire into possibilities otherwise. Rooted in the postdigital’s refusal to separate the digital from the material, postdigital feminist scholarship interrogates how technologies, bodies, and epistemologies are entangled with systems of colonial, capitalist, patriarchal, and racial violence. Postdigital citizen science, too, is fraught—its promise of participation often undercut by exclusions encoded in the very notion of ‘citizenship’. Yet, within these contradictions lie insurgent spaces of refusal, creativity, and reimagining. We offer a loose manifesto, not as a prescriptive call, but as an invitation to cultivate postdigital feminist citizen sciences from the ground up—from disobedient data practices to feminist counterpublics and speculative pedagogies. This is an alienated science of ruination from below: emerging from breakdown, grown in the cracks, and committed to dismantling platform patriarchy, colonial capitalism, and white supremacy. Our manifesto may be provisional, but our commitment is clear: to imagine and enact worlds beyond the fire.</p>
