The data layer is now reached through one pulled, version-pinned engagement
(`.project/concepts/data-layer/contract_polyfill-surface.md`, @1ecf511e9d).
That copy is the only reference: the provider's sources are never opened, and
what the contract does not answer is a gap raised with it, never worked around
here.
Surface
- `@ng-eventually/sdk` -> `@ng-eventually/polyfill`, one entry point.
- `configure` loses `getSession`, `normalizeId`, `currentUser`; the session
belongs to the package and its own `init` captures it.
- Placement is named by scope alone -- a session is one user, so the app no
longer passes an identity it had no way to obtain. This removes a constant
that made every user collide on one owner's document.
- `init(...)` then `await ensureIdentity()`, in that order, as one sequence:
React runs child effects first, so the two calls sat in the wrong order and
the contract now makes that throw.
- `sessionId` relayed as `string | number`, `materialize` -> `read`.
A rejection means "unknown", never "absent"
Four places treated a caught error as an empty result. The worst wrote a
duplicate participation: an unknown count read as zero defeated the idempotence
guard of `joinEvent`. Also fixed: a per-document count, a silently dropped
notification shown optimistically anyway, and a failed listing that left the
owned-event set empty and disabled the materializer for the whole session.
Shared identity is not a Festipod notion
A browser context is one user. The per-scenario identity plant is deleted at
its source and its five sites; what stays is the deployment's wallet file,
which the contract requires an application to serve.
Documentation
The doctrine no longer describes how the data layer works underneath: five
leaves whose subject was internals are gone, a dozen more are re-founded on the
contract's own words, and two frozen arbitrations about a deleted screen were
removed rather than left to mislead a future session.
Test harness
It can sign in at last: cucumber runs under node, which does not load `.env`,
so the harness never received the wallet material and every scenario silently
fell back to an empty local mode. A failed sign-in is now loud on both sides.
The suite also releases what it opens and exits on its own -- runs were still
resident hours after reporting, holding a browser and two servers.
Known red: `@data` cannot be measured. The served wallet accumulates and
nothing resets it; moving the browser profile aside does not, since the data
lives in the wallet file, not the profile.
RECADRAGE — la doctrine était trop étroite. rule_app-uses-sdk-surface-only
disait « le polyfill existe pour le WALLET VIRTUEL » : juste sur le fond, mais à
la lettre l'émulation des caps qu'on vient de livrer n'entrait pas dans son
mandat. Nouvelle formulation, portée aussi dans AGENTS.md :
@ng-eventually/client est un POLYFILL, et ce mot dit toute sa mission :
compenser l'écart entre le SDK tel qu'il devrait être et ce que NextGraph
fournit aujourd'hui. Le wallet virtuel en est la plus grosse pièce, pas la
totalité.
Avec la conséquence opérationnelle : quand quelque chose ne marche pas, la
question n'est jamais « comment contourner dans l'app » mais « qu'est-ce que le
polyfill doit compenser ». Un contournement côté app est une violation même
quand il fonctionne — il grave un état temporaire de NextGraph dans du code qui
doit lui survivre. Et l'ignorance de l'état d'implémentation est durcie :
ENTIÈREMENT, pas « sauf quand ça mord ».
NOUVEAU — data-layer/knowledge_sdk-surface : le contrat SDK cible, écrit dans CE
repo pour qu'un agent n'ait jamais à ouvrir le repo du polyfill. Couvre lectures
réactives, écritures, placement par scope, inbox, discovery, capabilities
(capFor/shareCap/publishRepoLink, livrées avec P1a), identité, sûreté SPARQL —
et les surfaces exportées mais interdites à l'app.
DOCTRINE PÉRIMÉE corrigée, après vérification dans le code :
- rule_document-per-entity décrivait la lecture via readEntities/readUnion/
registerDoc/bumpRead : ZÉRO site d'appel, readEntities.ts supprimé. Réécrite
sur watchShape/useShapeQuery. Le fond (un document par entité) est intact.
- brief_2026-07-06 §P3 réaffirmait une phrase que son propre encadré déclare
fausse : rétractée explicitement.
- knowledge_data-modes citait useShapeWithDefaults(), qui n'existe nulle part.
- ConnectScreen : les fiches avaient raison mais étaient vagues — l'écran existe,
est routé et monté, et est bien absent du registre. Précisé.
FIX CODE — build:orm était CASSÉ : il pointait ./src/shapes/, qui n'existe pas
(les shapes vivent sous src/shared/shapes/), et sortait en erreur. Donc la
commande que la doctrine prescrit après tout changement de .shex ne marchait
pas. Corrigé et vérifié : exit 0. La fiche avait raison, c'est le code qui était
faux — le point 4 approuvé, simplement situé dans l'autre fichier.
Régénération NON embarquée : lancer build:orm reformate les bindings et retire
l'annotation `: Schema`. C'est une montée de version d'outil, pas une correction
de contenu — elle mérite son propre changement validé, pas un passage clandestin.
Noté dans la fiche.

Enforce the project boundary: Festipod is written as if NextGraph were a mature,
finished SDK; @ng-eventually/client IS that SDK. NO current-NextGraph-state,
simulation, polyfill, shim, mono-store, store-id or broker-internal knowledge
remains in this repo — it now lives in the @ng-eventually/client repo.
- Dissolved the `nextgraph-platform` concept entirely (12 leaves — all
current-state/simulation, now in the lib's docs/). Rescued the genuine domain
parts into functional-domain/knowledge_data-scopes-and-discovery.md (which
entity → which scope; product-level discovery/notification intent), framed as
SDK usage with no mechanism.
- data-layer re-anchored to "how Festipod persists via the SDK": stripped
mono-store/private_store_id/RepoNotFound/DataCloneError/FESTIPOD_MULTISTORE.
Deleted the current-SDK compensation leaves (private-store-scope, multistore,
the 2026-03-17 ADRs, conditional-ng-init). Kept/reworded the domain + app
leaves; caveat_participation-deletion reduced to the domain contract.
- app-security reworded (isolation delegated to the SDK; app trusts it).
- AGENTS.md: dropped the nextgraph-platform row, reworded data-layer/
functional-domain/app-security, added the "Frontière SDK NextGraph" note.
- Fixed dangling [[links]]; concept lint clean (43 leaves).

Capture the multi-user design exploration as project knowledge + briefs:
- knowledge: NextGraph store types/permissions (+ inbox at protocol, SDK
exposure, local repo path); integration model (iframe, where the verifier
runs, generic JS plumbing, ngd stateful, build-time broker target)
- briefs: multi-store refactor; authorization matrix + query inventory +
derived store partitions; temporary fork to expose the inbox (3 layers:
SDK fork, Coolify self-hosting, Festipod integration; libs via build:ng)
- fix stale @ng-org versions (alpha.11 -> alpha.13) and a broken
decision-record link in data-layer.md

- Port modern clean theme (DM Sans, orange accent, app-* CSS classes)
and screen redesigns from festipod-mockups; replace sketchy Ubuntu
theme. New shared components: BottomNav, EventCover, EventMeetingPoints,
Toast, AvatarStack, Tag, RelevanceIcon.
- Restructure from prototyping shell to real mobile web app:
path-based routing (History API), Gallery/DemoMode/PhoneFrame removed,
Storybook setup for screen/component browsing.
- ConnectScreen ported from mockup (QR-based user connection); routed
at /profile/connect, wired from FriendsListScreen.
- Dev-only auto-seed of NG wallet when empty
(gated on NODE_ENV !== 'production'); bootstrapWallet already
self-checks for non-empty ngSet so safe even in race conditions.
- Render-based @ui test infrastructure: happy-dom + LocalDataProvider +
RouterProvider via src/shared/test-harness/renderHelper.tsx, exposed
on the world as renderedDoc. world.hasText/hasField/hasElement prefer
the rendered DOM and fall back to source for backward compatibility.
- Migrate 25 brittle @ui assertions from regex-on-source to DOM
queries; delete implementation-detail tests (showDuplicateWarning,
importableEvents, importedFrom — anti-patterns per the new contract).
Update feature files where the UI changed: "Mes amis" → "Mon réseau",
"Mes événements à venir" → "À venir" on home, Thématique removed
from create-event wizard, etc.
- Path-based @e2e steps (pushState + popstate dispatch) replacing the
legacy "#/demo/…" hash routing tied to the deleted Gallery.
- Add .project/knowledge/test-layer-contracts.md defining the role of
each test layer (@ui = display with seed data + DOM, @data = mutations
through NG broker, @e2e = critical user journeys) with anti-patterns
and migration consequences.
Test status: 75 passed / 71 skipped (explicit "non implémenté")
/ 2 failed (pre-existing @wip on ngSet.delete() NG ORM limitation).

- Add auth e2e feature scenarios and step definitions
- Update docs: bdd-testing, data-layer-testing, data-layer, AGENTS.md
- Add decision record for conditional NG init approach
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Rename steps/frontend/ to steps/ui/ across all modules and shared
- Add data-layer test harness (mock + real broker modes) with Playwright
- Add inscription data-layer steps (@data scenarios)

Participation), session management, and FestipodDataContext with dual-mode
operation (connected via NextGraph or local seed data)

steps in event/steps/, user steps in user/steps/, shared generic steps remain
in shared/steps/
- Set up multi-layer BDD structure (frontend/backend/e2e steps per module)
- Add project documentation (AGENTS.md, .project/knowledge/)
