Caller-side shim in el_runtime.c maps EngramNode/Edge <-> StoreNode/Edge; engine keeps zero soul deps (libengram boundary, design §10). Flag off = today's JSON path byte-for-byte (proven: no neuron.egm created, graph identical). Flag on = engram_open (import snapshot.json once into neuron.egm, else WAL-replay) + resident load; node/edge create + forget dual-write via guarded hooks. Files renamed engram.store->neuron.egm, engram.wal->neuron.wal. Gate: M3 parity PASS (graph on==off byte-exact modulo ordering; snapshot round-trip; reboot-from-egm with snapshot.json deleted; activation set+sequence identical; ASan/UBSan clean). M1 33/33 + M2 36/36 green post-rename. Known gap (pre-flip): in-place hebb/WM/activation_count updates during activation are not yet persisted to the store (create/connect/forget are). Must close before live flip so learned edges survive restart.
