Polyfill capabilities landed for Festipod's T02 features (all generic,
zero-domain — the consumer injects the domain).
- inbox: implement the previously-stubbed namespace. post(target,{from?,
payload,ts?}) deposits {from,payload,ts} as RDF via docs.sparqlUpdate (the
real injected ng, never makeNg); read/materialize + watch emulate the curator
in-lib (deposits read via docs.sparqlQuery). `from` optional = anonymity.
- write-guard: caps.hasWritePolicy() + ng-proxy.sparql_update rejects when the
target doc is under a write policy and the current user lacks its write cap;
passthrough otherwise (no regression). Read-cap registry unchanged.
- sparql.ts (new): escapeLiteral / escapeIri / assertNuri, exported from index.
store-registry now escapes every literal and validates/encodes every IRI-
position value — closes a SPARQL-injection hole where an untrusted username
could inject triples into the shim (the account→doc-NURI trust root).
Tests: inbox, sparql (incl. injection), ng-proxy write-guard, isolation-active.
68 tests pass; tsc --noEmit rc=0.

ng-eventually
A generic polyfill layer over the NextGraph JS SDK.
NextGraph's JS SDK does not yet expose cross-wallet reads, capabilities, inboxes
or group stores. ng-eventually lets an app behave as if those existed today, by
emulating them on top of a single shared wallet / broker. It is generic:
it contains no application domain — the consumer injects its shapes and the
acts of granting access.
The name: eventually NextGraph will ship these features; until then this layer fills the gap (and nods at eventual consistency / events).
Packages
| Package | Role | At migration |
|---|---|---|
@ng-eventually/client |
SDK-identical wrapper the app imports instead of @ng-org/web / @ng-org/orm. Adds the polyfills the broker/verifier will do natively (shared-wallet login, capability enforcement, anticipated cap/inbox methods). |
Disappears: the app points back at the real SDK (build alias removed). |
A global-index curator package is deferred. NextGraph is mono-user with no global data (apps/services see only what the user shares; there is no multi-user backend). A global index would come from a singleton app (a global document administered by the developer) — not implemented and uncertain, and simpler paths may exist. So no second package for now; it will be (re)introduced once the global-index mechanism is decided. The curator must never be bundled in the client → it will be a separate package when it lands.
Design principle
The application code is written as if the target NextGraph existed. All compensation lives here, beside the app. Migration = remove this layer; the app code (SDK-shaped) is unchanged.
- SDK-identical surface: the client wraps the real
ng(a Proxy that forwards everything and overrides only what must be emulated) anduseShape. The real SDK is injected viaconfigure()(no hard import → build-alias safe + testable). - Authorization = emulated capabilities: documents carry grants; the client enforces them generically (read filter + write guard). The app attaches grants via cap operations — same as it will in the target. No policy is injected.
- Inbox: the client
inbox.post()deposits; materialization (the curator) is deferred with the global-index mechanism — see the note above. - Tests of the polyfill (against a real broker) live in this repo, so the consuming app can test its features against a mocked, clean API.
Status
Scaffold. Mechanisms are stubbed with TODO(broker) / TODO(polyfill) where
real NextGraph wiring is required.
