README: new section with a recap table (11 rows) — for each emulated behavior: what the consumer sees (SDK-shaped API), how it's emulated on one shared wallet, the real NextGraph target, and the lib-only migration. Makes "emulated ≠ real, migration is a lib-only swap" explicit. simulation.md: opening banner that EVERYTHING in the file is emulation pending real NextGraph; corrected the stale read-path paragraph (per-doc anchored, never an anchorless union-scan). read-model.md: reactivity bullet aligned to per-doc.
