Enforce the boundary in code-comments and doctrine (adversarial-review cleanup): - App comments in the data plane no longer narrate the SDK's internals: "emulated curator"→"the inbox read", "fan-out"→"discovered", removed store-placement reasoning and "polyfill/shim/mono-store" wording (FestipodDataContext, registration, storeRegistry, ngSession, AccountContext, isolation, sharedWallet, AccessGateScreen). Executable logic unchanged. - Removed dangling references to the dissolved `nextgraph-platform` concept and `brief_2026-06-15_shared-wallet-shim` from app code. - knowledge_nextgraph-stack: dropped "mécanique d'émulation" from the boundary note. - Settled and deleted all concept _debt.md (confirmatory; target leaves clean). (Test-infra under workshop/ + generated features.ts still carry some simulation vocabulary — parked as a separate below-SDK decision.)
