Constellations respond to crisis through four pathways: adaptation (metanarrative revision), merger (two constellations fuse with narrative residue), fragmentation (one splits into competing sub-constellations), and total narrative replacement. This extends institutional-punctuated-equilibrium (LEO-DIA-04) which describes the pattern but not the outcome typology. AI does not merely eliminate the pause between capability surges - it changes the communication substrate that constitutes constellations, potentially altering which crisis pathways are available.

Strongest rival: The four-pathway typology is too neat - real constellation crises produce messy combinations of adaptation, merger, fragmentation, and replacement simultaneously, and the typology obscures more than it reveals
