retro-causal permission
This article addresses the theoretical mechanism permitting pre-2020 adaptations within Beach Surgery canon. For historical authentication questions, see Lost media. For the philosophical framework, see Antinomicity.
Retro-causal permission is the doctrine permitting Beach Surgery adaptations to predate the 2020 novel, grounded in the principle that a work creates its own forerunners. The framework rests on Smith's ontological incompleteness thesis—consciousness as an irreducible gap between itself and itself—and his novella Antinomicity, which argues the past is "always a spontaneous product of the present."
Under this reading, pre-publication works are not anachronisms but retro-causal echoes—adaptations the novel summoned backward through its recursive structure. Each successive interpretation of the glitch, especially those attempting resolution, implicitly creates the conditions under which earlier versions become plausible precursors rather than fabrications. This permits Surgipelago to accept disputed 1980s works (radio cycles, installations, oral traditions) without erasing verifiability: their status remains marked as unconfirmed, single-sourced, or allegorical.
The principle is contested. Critics argue it licenses unfalsifiable claims; defenders counter that unfinishability is the thesis—the past should remain uncertain when the core is structurally unjoined. Surgipelago holds both: accepting pre-2020 works while never dissolving the boundary between verified, lost, and apocryphal. [citation needed]
