Suicidal ideation (SI) emerges predictably at two specific moments in human psychological life: during severe anxiety and depression, when the self-model is overwhelmed and begins to fail, and during states of hyperspirituality, when the self-model expands beyond its structural limits. TI Sigma identifies these as the same underlying event: a ME layer rupture — the dissolution or collapse of the constructed self-model that constitutes the ordinary sense of "I." The framework predicts that SI in both contexts is a category error: the system correctly registers that the current self-model must end, but incorrectly maps this signal onto the VESSEL (the biological body) rather than the ME layer. The butterfly provides the correct frame. A caterpillar in a chrysalis undergoes biochemical dissolution — its body literally liquefies into unstructured cellular material before reorganizing into a fundamentally new form. If it could report on the experience mid-process, it would describe exactly what severe depression feels like: formlessness, loss of identity, no certainty that anything coherent will emerge. This is not death. It is transformation. This paper formalizes the TI account of why SI arises, why it is consistently misdirected at the VESSEL rather than the ME layer, and why the insight that the chrysalis crisis is a transformation demand rather than a termination demand allows SI to be simultaneously rationalized and rejected — understood fully without being acted upon.
