Bug: à la reconnexion, resolveAccount lisait le shim depuis le store-root (did🆖${privateStoreId}), NON abonnable → pas de barrière first-State → un "0 rows" à froid est ambigu → le retry (resolveAccountReliably/provisionRetry) échoue → nouveau compte provisionné → FORK → données du compte invisibles. Cause NextGraph (vérifiée nextgraph-rs): "trouvable-sans-lookup" (store-root) et "abonnable" (did:ng:o:<RepoID aléatoire>) sont DISJOINTS — pas de doc à la fois devinable et attendable → une résolution shim purement barrière est impossible. Fix (indirection pointeur → doc-shim abonnable): - Les AccountRecord migrent dans un doc-shim doc_create'd (did:ng:o:..., a une barrière). - Un pointeur écrit-une-fois dans le store-root (<shim:root> <shim:shimDoc> <docShim>) le nomme. resolveShimDoc lit le pointeur → ensureRepoOpen(docShim) [barrière] → lecture de compte AUTORITATIVE (cold 0 = absent pour de vrai). Retry de compte SUPPRIMÉ. - Micro-garde résiduel (pointerGuard, ex-provisionRetry) sur le SEUL triple pointeur écrit-une-fois; ne peut jamais forker un compte; fork de pointeur réconcilié au doc-shim canonique (lexicographiquement-min), sans perte. - Migration: migrateLegacyRecords copie (pas déplace) les comptes de l'ancien store-root vers le doc-shim avant toute conclusion "absent"; idempotent; wallet neuf → no-op. Tests: unit 128/128, e2e réel 42/42 (CONTRACT 2 = non-fork du compte à la reconnexion), red-before/green-after prouvé.

@ng-eventually/client
Two entry points — the data-plane is SDK-identical, the polyfill bootstrap is separate:
| Import | Surface |
|---|---|
@ng-eventually/client |
The same signature as the SDK — ng, useShape, inbox (+ types). A drop-in for @ng-org/web / @ng-org/orm; as NextGraph matures it resolves to the real SDK (build alias removed) with no code change. |
@ng-eventually/client/polyfill |
The only non-SDK surface — configure, setCurrentUser, and capability helpers (getCaps, grantRead, canRead/canWrite). It falls away as NextGraph matures. |
// bootstrap (the only non-SDK call) — inject the real SDK
import { configure } from "@ng-eventually/client/polyfill";
configure({ ng: realNg, useShape: realUseShape, sharedWallet, currentUser });
// from here on, a pure SDK surface:
import { ng, useShape, inbox } from "@ng-eventually/client";
await ng.doc_create(/* … */);
const set = useShape(MyShape, scope); // filtered to what the identity may read
await inbox.post(targetInbox, ref); // deposit (anticipated SDK API)
Principle — the polyfill compensates, it never extends
The polyfill's ONLY reason to exist is to bridge a NextGraph implementation gap or a bug. Every non-SDK surface must map to a capability NextGraph will provide natively, and must fall away at that point. The polyfill MUST NOT add functionality of its own — no bespoke features, no observability/tooling, no convenience API that isn't strictly "NextGraph will do this natively later." The test for any proposed addition: does it compensate a real, exhibited NextGraph gap or bug? If not, it does not belong here — build it in the consumer application, not in the polyfill. Corollary: a compensation whose gap is not actually exhibited on the target broker is dead weight, not defensive code — it should be removed, not kept "just in case."
What the polyfill adds on top of the real SDK (each emulated for now, native as NextGraph matures):
- Shared-wallet identity (one wallet for everyone; the current identity id is relayed to the SDK).
- Capability enforcement — a read filter + write guard over emulated grants attached to documents; the app declares a document's read policy and issues directed read grants.
- Anticipated methods (inbox
post, capability ops) with their future-SDK shapes, emulated for now.
Generic: no application domain. The consumer application injects its shapes and performs the acts of granting access. The relationship concept ("who is connected to whom") is the consumer application's own — the client exposes only directed per-document read grants.
