The polyfill had only fake-ng unit tests; real-broker behaviour (SPARQL graph
round-trip, doc_subscribe marshaling, inbox/index) was only ever exercised by
borrowing Festipod's harness. Add packages/client/e2e/ — a standalone Playwright
harness in the SDK's own domain: a minimal SDK page (configure() + the real
@ng-org/web ng, a window.__sdk bridge, zero Festipod domain) loaded in the broker
iframe on the real broker, authenticating with a DEDICATED wallet (name
ng-eventually-e2e, profile e2e/.playwright-profile-lib — gitignored, separate from
Festipod's). Runner: bun run e2e/run.ts (script test:e2e); not mixed into bun test.
Covers, against the real broker (23 checks, all green): docCreate; sparqlUpdate/
Query anchored default-graph round-trip; readUnion N-doc + per-doc tolerance + cap
gate; doc_subscribe initial+write+unsub and subscribeDocs per-doc isolation; inbox
post/read/watch + spoof guard; discovery submit/read/watchIndex + reserved-account
isolation; store-registry idempotency + bounded listMyEntityDocs + scope resolvers;
caps read-filter (in-memory, honestly scoped); IdentityStore.
Finding (reported, not a failure): on @ng-org/web 0.1.2-alpha.13 an anchored
INSERT DATA { GRAPH <plainNuri> {…} } DOES round-trip (no phantom graph) — several
lib comments assert the opposite; stale, to reconcile. Behaviour is unaffected (the
lib writes the always-safe no-GRAPH default-graph shape). bun test still 91 pass.

Generic polyfill layer that makes a single NextGraph broker behave like the
not-yet-shipped multi-user NextGraph (emulated capabilities + inbox). Zero app domain.
@ng-eventually/client exposes an SDK-identical surface (ng, useShape, inbox); the
polyfill bootstrap (configure + capability helpers) is isolated under /polyfill, so
the main entry stays a drop-in for @ng-org/web|orm. The real SDK is injected at
configure() (no hard import → build-alias safe + testable).
Scaffold: NextGraph wiring stubbed with TODO; capability helpers implemented and
unit-tested (4 tests, typecheck clean). The global-index curator is deferred — in
NextGraph apps/services are mono-user with no global data.
