Le nom @ng-eventually/sdk entrait en collision avec le SDK de NextGraph, dont ce paquet est justement un polyfill. Impossible d'écrire « le SDK » sans lever l'ambiguïté à chaque phrase — et le contrat publié, lu par une application, était le pire endroit pour laisser traîner ça. packages/sdk → packages/polyfill, @ng-eventually/sdk → @ng-eventually/polyfill, contract_sdk-surface → contract_polyfill-surface, e2e/sdk-entry.ts → e2e/polyfill-entry.ts, docs/sdk-reference.md → docs/polyfill-reference.md. Les occurrences de « SDK » qui désignent celui de NextGraph restent intactes, y compris les chemins dans nextgraph-rs (sdk/js/orm, sdk/js/web). Le tri s'est fait occurrence par occurrence, pas par substitution. Le contrat énonce désormais son identité en une phrase : « This package is a polyfill of NextGraph's SDK. »

# app-contract — the boundary between this library and the applications that use it
|
|
|
|
This library exists so an application can be **written today against the NextGraph that does not ship yet**, and keep its code when it does. Everything under this concept governs that boundary: what the package publishes, what a caller may rely on, what it must not, and what disappears at migration.
|
|
|
|
The distinguishing question, asked at every choice — published signature as much as internal mechanism: **does the target do this?** If it does it differently, we do it their way, whatever that costs. *Would a caller have to unlearn it?* comes second, and measures how bad a divergence is — never whether one is allowed. See `rule_no-divergence-from-nextgraph`.
|
|
|
|
This repo is the **provider** of `contract_polyfill-surface`; consuming applications live in other repos and pull it. The per-symbol ruling, with an epistemic label on every target-side claim, stays here in `docs/api-contract.md` — that is maintainer material, not the engagement.
|

|
## Read first
|
|
|
|
- `contract_polyfill-surface` — the engagement itself, written from the caller's point of view.
|
|
- `rule_no-divergence-from-nextgraph` — the test that decides what may be built at all.
|
|
- `knowledge_what-an-app-deletes-at-migration` — the two fates a published symbol can have.
