docs: dire partout que la lecture par lot n'existe plus

Browse Source 
Le contrat publie et l'api-contract etaient traites avec le retrait lui-meme ;
restaient les documents qui decrivaient readUnion comme la primitive de
lecture du paquet, ou qui nommaient le module disparu.

Ce que les lecteurs apprennent maintenant : lire un document, c'est
docs.sparqlQuery ancre dessus, et lire plusieurs documents, c'est cet appel
une fois par document -- avec la decision sur une lecture qui echoue ecrite
au point d'appel. Deux consequences sont dites plutot que decouvertes : une
lecture refusee leve au lieu de rendre une liste vide, et les sujets sous le
prefixe reserve urn:ng-eventually: reviennent dans le resultat, a l'appelant
de les ignorer -- sans aucun gain de droits, les deux registres qu'un
document ordinaire porte etant l'adresse de sa boite et, pour un document
public, la cle que son magasin sert deja a qui la demande.

Les briefs dates ne sont pas touches : ils decrivent un etat de juillet, et
le reecrire falsifierait ce qui avait ete decide alors.

# Internal contract — what `@ng-eventually/polyfill` keeps off its surface, and what NextGraph does or would do about each subject
> **Updated 2026-08-03, after the source layout was reorganised by migration fate** (`docs/source-layout-by-fate.md`). Paths, and three names, changed under this document: `readModel` became the directly-exported `readUnion`; `accounts` / `AccountRecord` / `AccountStorage` became `virtualUsers` / `VirtualUserRecord` / `VirtualUserStorage` (module `shared-wallet/virtual-users.ts`); `store-registry-api.ts` became `surface/placement.ts`. Two modules were created and are covered here: `emulated-verifier/branch-registers.ts` (the four durable registers, split out of the shim) and `shared-wallet/bootstrap.ts` (the injection store, split out of the `/polyfill` entry). The subject-by-subject rulings below are unaffected — what moved is where the code lives, not what it promises.
> **Updated 2026-08-03, after the source layout was reorganised by migration fate** (`docs/source-layout-by-fate.md`). Paths, and three names, changed under this document: `readModel` became the directly-exported `readUnion` (itself removed in `1.0.0-dev.8`); `accounts` / `AccountRecord` / `AccountStorage` became `virtualUsers` / `VirtualUserRecord` / `VirtualUserStorage` (module `shared-wallet/virtual-users.ts`); `store-registry-api.ts` became `surface/placement.ts`. Two modules were created and are covered here: `emulated-verifier/branch-registers.ts` (the four durable registers, split out of the shim) and `shared-wallet/bootstrap.ts` (the injection store, split out of the `/polyfill` entry). The subject-by-subject rulings below are unaffected — what moved is where the code lives, not what it promises.
**Scope.** The complement of [`docs/api-contract.md`](./api-contract.md): every module export under `packages/polyfill/src/` that is NOT reachable from the published entry point (`package.json` maps exactly `.` → `src/index.ts`). A consumer never reads this document; a maintainer does. The internal code is held to the same standard as the surface — as close as possible to what NextGraph does or plans — so every subject below carries the same target-side analysis. Written 2026-08-04, verified against the `nextgraph-rs` clone (HEAD `213338f6`) and the installed `@ng-org/web@0.1.2-alpha.13` declarations (`node_modules/.bun/@ng-org+web@0.1.2-alpha.13/node_modules/@ng-org/web/dist/index.d.ts`, hereafter `index.d.ts`).
**How the boundary was computed — mechanically, from the `export` statements.** `index.ts` re-exports wholesale (`export *` / `export * as ns`) from `types.ts`, `inbox.ts`, `docs.ts`, `surface/read-model.ts`, and by name everything `surface/use-shape.ts`, `surface/watch-shape.ts`, `lifecycle.ts`, `sparql.ts` export, and `subscribeDoc`/`subscribeDocs`/`docChangeType` (+ types) from `subscribe.ts`; its `storeRegistry` namespace is the **`surface/placement.ts` slice only** (`createEntityDoc`, `listMyEntityDocs`, `resolveScopeGraph`, `resolveWriteGraph`, `openDocumentInbox`). `model/nuri.ts` is now internal in full — the guards `isNuri`/`hasReadCap` stopped being published when the entries became permissive-in (`NuriLike` validated at the door). *(The second entry, `polyfill.ts`, was merged into `index.ts` on 2026-08-07, and the polyfill-era block was then cut to ONE published call, `configure`. `configureStoreRegistry`, `setCurrentUser` and `connectedUser` became internal the same day — folded, replaced by the gate, and awaited inside it respectively; the machinery accessors and test resets are internal too. All four are inventoried below.)* Everything else that carries `export` in a `src/` module is internal and inventoried here. Eight modules are internal in their entirety: `shared-wallet/access-log.ts`, `emulated-verifier/machinery.ts`, `surface/ng-proxy.ts`, `emulated-verifier/open-repo.ts`, `shared-wallet/outbox-log.ts`, `shared-wallet/physical.ts`, `emulated-verifier/reach.ts`, `emulated-verifier/read-filter.ts`. Four are internal in part: `nuri.ts`, `emulated-verifier/connect.ts`, `subscribe.ts`, `shared-wallet/account-registry.ts`.

All four are inventoried below.)* Everything else that carries `export` in a `src/` module is internal and inventoried here. Nine modules are internal in their entirety: `shared-wallet/access-log.ts`, `emulated-verifier/machinery.ts`, `surface/ng-proxy.ts`, `emulated-verifier/open-repo.ts`, `shared-wallet/outbox-log.ts`, `shared-wallet/physical.ts`, `emulated-verifier/reach.ts`, `emulated-verifier/read-filter.ts`, and — since `1.0.0-dev.8`, when `readUnion` and `UnionSubject` left the entry — `surface/read-document.ts` (the former `surface/read-model.ts`). Four are internal in part: `nuri.ts`, `emulated-verifier/connect.ts`, `subscribe.ts`, `shared-wallet/account-registry.ts`.
**Labels** are those of `docs/api-contract.md`: **PASSTHROUGH (level 3/2, VERIFIED)**, **LEVEL-1 SHAPE (model VERIFIED, JS surface ASSUMED)**, **ASSUMPTION**, **NO COUNTERPART**. Level numbers per `README.md` § *The three references*: 3 = JS ORM, 2 = wasm binding (`@ng-org/web`), 1 = Rust engine. One label recurs here that the surface contract rarely needs: **NO COUNTERPART, shared-wallet machinery** — the code below the emulation's floor, which the target has no image of because the target has no shared wallet. Per the design principle, an absent implementation is never treated as evidence about the future.

- The opening mechanism is **level 2, VERIFIED as a composition**: `doc_subscribe` exists (`sdk/js/lib-wasm/src/lib.rs:1908`), and the push variants `TabInfo`/`State`/`Patch` are the engine's `AppResponseV0` (`engine/net/src/app_protocol.rs:1354-1358`). The ORDER (TabInfo first, then the initial State) and "first State = presence guaranteed, absence definitive" are **empirical, pinned by the in-repo e2e CONTRACT-3 probe — an ASSUMPTION about ordering as far as upstream is concerned**: no upstream statement fixes the push order, so a future reordering upstream would silently break the barrier. Bound: the e2e probe fails loudly if the order changes.
- "Hold a live subscription to keep the repo open" — **ASSUMPTION** (nothing upstream documents subscription lifetime as what retains a repo in `self.repos`); observed to work, bounded by the same probe.
- **Defect — the header's mechanism claim is contradicted at the source (see Findings F2).** `open-repo.ts:10-12` says an anchored `sparql_query` on a repo absent from `self.repos` "silently returns 0 rows (never a `RepoNotFound`)". Verified upstream: absence from `self.repos` yields `Err(NgError::RepoNotFound)` (`request_processor.rs:264,269`), the ReadQuery arm converts it into `AppResponse::error` (`:1293-1296`), and the web binding REJECTS the JS promise with it (`sdk/js/lib-wasm/src/lib.rs:606`). The observed 0-rows-no-error behaviour has two candidate explanations that the source does support: a persistent verifier reloads every known repo into `self.repos` at `Verifier::load` (`engine/verifier/src/verifier.rs:535-560`) so the repo is present-but-unsynced (a genuine 0-row read), and/or the lib's own per-doc tolerance (`readUserStore`, `surface/read-model.ts` per-doc catch) converts a rejection into an empty result. The healed symptom is real and the fix correct; the stated mechanism is not established, and a maintainer reasoning from it would mispredict behaviour whenever the verifier is not persistent.

- `SyncState` and `getSyncState` are lib-invented vocabulary — **NO COUNTERPART** (upstream has no consumer-facing "sync state of a repo" API at any level; `OrmSubscription.readyPromise`, `sdk/js/orm/src/connector/GraphOrmSubscription.ts:260`, is the closest level-3 signal, per-subscription not per-repo).
- At migration the whole module becomes "open the store by cap at bootstrap" (native) and is removed with the shim.
