Phase A du refactor des lectures. Surface la barrière de sync interne
(open-repo `getSyncState`) dans une API useQuery-shaped, en anticipation de la
mise à jour prévue de useShape par NextGraph — distingue nativement « sync en
cours » de « synchronisé mais vide ».
`watchShape<T>(shapeType, scope): { getSnapshot(): ShapeQuery<T>, subscribe(cb),
refetch() }` avec `ShapeQuery = { data, isPending, isSuccess, isError, error }`.
OBSERVABLE (pas de dépendance React — l'app câblera useSyncExternalStore en
phase B) ; getSnapshot rend une référence stable.
- Scope LOGIQUE (public/protected/private) résolu au wallet virtuel :
listMyEntityDocs(getCurrentUser, scope) + découverte foldée pour public.
- isPending tant que la barrière n'est pas atteinte / 1er readUnion non rendu ;
isSuccess après ; timed-out → isSuccess (best-effort, pas isError).
- Réactif SANS polling : subscribeDoc sur les docs + le doc d'index de scope
(+ index découverte) → re-read/re-résolution au push ; souscriptions idempotentes.
- Générique : aucune logique domaine Festipod dans le lib ; filtre par la shape
SHEX (rdf:type). Pas de double filtre cap.
gate : tsc 0 ; bun test 120 (+4 : pending→success, synced-vide, réactif, timed-out) ;
test:e2e 42 passed (+scénario broker réel : isPending au 1er snapshot → isSuccess
avec données, scope vide → isSuccess data:[]).

Preuve e2e (wallet frais, broker RÉEL rapide : 1er State 1-2 ms) : le private
store est synchronisé au login, la lecture du shim réussit à froid — le « fork sur
lag » que anti-fork compensait n'est PAS exhibé. Par le principe du polyfill
(compenser un gap RÉEL, jamais du poids mort), et par la règle no-polling :
- la version retry = polling (bannie) ;
- la version barrière `ensureRepoOpen(privateStore)` = CASSÉE (un store n'émet pas
de `State`, la barrière timeout systématiquement → CONTRAT 2 e2e échouait) ;
- le gap = non exhibé.
→ `ensureAccount` fait un `resolveAccount(id)` SIMPLE (une lecture, provision si 0).
`resolveAccountReliably`, `_forceOpenedSyncState` retirés ; `provisionRetry` gardé
optionnel @deprecated (ignoré) pour ne pas casser les 8 tests qui le passent.
`ensureRepoOpen`/`getSyncState` inchangés (chemin de lecture open-repo).
gate : tsc 0 ; bun test 116 ; test:e2e 39 passed, CONTRAT 2 VERT (« same account,
no second provisioning »). Le ~10s du re-resolve public est du scaling anchorless,
pas de la lenteur broker (broker mesuré à 1-2 ms).

Le polling est un anti-pattern NextGraph (par abonnement). La résolution de compte
retentait ×8 la lecture du shim tant qu'elle rendait 0 (lag de sync) — c'est du
polling. Remplacé par la BARRIÈRE d'abonnement, déjà le mécanisme de open-repo :
- `resolveAccountReliably` : `await ensureRepoOpen(did🆖${privateStoreId})`
(subscribe + attendre le 1er State — le shim vit dans le graphe du private store),
PUIS lecture UNIQUE. Après la barrière, 0 ligne = compte réellement inexistant →
provision 1×, lignes présentes = réutilisé (garantie NO-FORK préservée). Plus de
boucle de re-lecture.
- timed-out (barrière expirée) : throw explicite, NE provisionne PAS (un provision
sur sync incomplète re-forkerait). Le « trop long » est un signal, pas un feu vert.
- fake ng sans doc_subscribe : ensureRepoOpen no-op → lecture immédiate (unit intact).
- `_forceOpenedSyncState` : helper test-only (underscore, non ré-exporté).
anti-fork.test.ts réécrit (5 tests : no-fork, neuf→1 provision, idempotence, fake
no-op, timed-out→throw) ; plus aucun test de comptage de retry.
gate : tsc propre ; bun test 117. e2e À RE-VALIDER quand le broker répond (dégradé
ce jour : crash Chromium post-connexion) — la barrière ensureRepoOpen est déjà
validée e2e (CONTRAT 3 + reconnexion) en broker sain. provisionRetry devient un
champ mort de StoreRegistryDeps (nettoyage ultérieur).

Cause racine mesurée (broker réel, access-log) : à la première resolveAccount
d'une session, le record de compte tout juste persisté (ou d'une session
antérieure) peut lire 0 lignes à cause du LAG DE SYNC broker. ensureAccount
interprétait ce 0 comme « compte inexistant » et RE-PROVISIONNAIT un second jeu
de docs de scope (docPublic/docProtected forkés) → les lectures d'une session
tombaient sur un jeu, celles d'une autre (ou après drop de cache) sur l'autre
jeu vide → données « perdues » à la reconnexion.
Fix : `resolveAccountReliably` (store-registry.ts) — retry borné (ouverture du
repo d'ancre shim + backoff plafonné, défaut 8 tentatives / ≲8.5s) AVANT que
ensureAccount ne décide qu'un compte est neuf. Provisionne seulement si, après
le budget, la lecture rend toujours 0 (compte réellement neuf). Budget injecté
via StoreRegistryDeps.provisionRetry (polyfill.ts), ON en prod ; tests unitaires
à provisionRetry synchrone (attempts:1, fake sans lag). Idempotence de session
préservée par accountCache (hit court-circuite, déterministe).
Portée : corrige le déterminisme de provisioning. NE suffit PAS à réparer la
reconnexion (le read public à 0 same-session subsiste, cause distincte encore à
mesurer de façon déterministe — le lag broker rend les mesures non-reproductibles).
Complémentaire du commit open-repo précédent, pas redondant.
gate : tsc --noEmit propre ; bun test 91 pass ; auth @data (vide/distinctes) verts.

Défaut visé : sur une session verifier fraîche (reconnexion), la lecture ancrée
tape des repos pas encore ouverts dans self.repos → 0 ligne. Nouveau module
`open-repo.ts` : `ensureReposOpen`/`ensureRepoOpen` ouvrent/souscrivent un repo
via la primitive existante `subscribeDoc` (doc_subscribe) et attendent le push
d'état initial (borné, sans polling) AVANT la lecture ancrée. Câblé en amont de
`readUnion` (read-model) et `readScopeIndex` (store-registry). Idempotent par
session (Set des NURI ouverts + Map in-flight ; ré-ouverture si la session
injectée change). No-op si le `ng` injecté n'a pas doc_subscribe (fake unitaire).
État — NON MERGÉ, incomplet :
- AIDE le PROTECTED : la participation remonte au cold-start (mesuré app, timing
un peu bruité).
- N'ADRESSE PAS l'accueil PUBLIC : `readScopeIndex` de l'index public rend 0 même
côté écrivain même-session — le fix ouvre le repo mais l'index reste vide. Le
code d'index lib est prouvé scope-symétrique, donc la cause du public est
ailleurs (broker/store ou chemin app), À MESURER SOUS BROKER (actuellement
injoignable). Nécessité du fix elle-même non prouvée en e2e lib (broker down).
gate broker-indépendant : tsc --noEmit propre ; bun test 91 pass (worker).
Inclut le scaffolding e2e de repro reconnexion (broker/run/sdk-entry).

Observability probe for the shared-wallet isolation footgun: on one physical
wallet several virtual identities coexist, and a read must never surface a doc
scoped to another identity. When it does (B reading A's doc), the leak is
invisible in the data — it looks like a normal read. This makes it VISIBLE.
Every real read/write is logged, prefixed by the ACTIVE virtual identity
(getCurrentUser → the account the op is scoped under, NOT the constant shared
physical wallet id). Reads append the row count — a strong leak signal:
[urn:festipod:user:bob] READ did:ng:o:docA (readDoc) → 3 rows
Instrumented at the LOW common point in docs.ts: every read routes through
sparqlQuery, every write through sparqlUpdate, container creation through
docCreate. Callers pass a semantic label (readDoc|readUnion|listMyEntityDocs|
writeEntity|deposit|…) that is a lib-internal probe param, NOT forwarded to the
real `ng` (preserves docs.test.ts exact-forwarding assertions).
OFF by default → one boolean read on the hot path, zero output. On via
configure({ debugAccessLog: true }) or env NG_EVENTUALLY_ACCESS_LOG=1 (no code
change). Polyfill-era; removed at the real multi-store migration.
tsc --noEmit: 0 errors. bun test: 91 pass.

The lib e2e harness now characterizes all three SPARQL graph shapes against the real
broker (24/24): (a) no-GRAPH anchored write round-trips; (b) an explicit anchored
GRAPH <plainNuri> ALSO resolves to the same repo (no phantom graph) — the earlier
'targets a phantom graph, does NOT round-trip' claim is FALSE on @ng-org/web
0.1.2-alpha.13; (c) an anchorless GRAPH ?g scan spans every named graph (O(wallet)
union, 32 graphs) — TRUE, re-verified.
Reconcile the comments accordingly: inbox.ts / store-registry.ts drop the false
phantom-graph justification (no-GRAPH stays as the canonical, always-safe shape — a
simplicity choice, not a round-trip necessity; re-verify via e2e if the broker
version changes). read-model.md keeps the anchorless-O(wallet) rationale (the real
reason reads are per-doc anchored) and appends a note distinguishing the variable
GRAPH ?g SCAN from a constant GRAPH <D> WRITE. No new absolute introduced.

Align the polyfill's surface and docs with the verified NextGraph reality and
remove application-level concepts:
- Identity is an ID, not a username: AccountRecord.id, shim predicate shim:id,
normalizeId; accounts core becomes IdentityStore (set/clear/get) — the faux
login/logout framing is gone (identity is set at wallet-import time).
- Relationship/connection is an application concept, not a platform primitive
(NextGraph has no bilateral-connection primitive: grantee is unpersisted
scaffolding, cap-send is unimplemented). Remove connections.ts; caps exposes
only a directed grantRead(doc, granteeId) + a read-only protectedDocsOf(owner).
Delete the now-dead isolation.ts social-visibility axis.
- Inbox docs: NextGraph has no separate curator — the recipient's own verifier
unseals and applies each queued sealed message inline (process_inbox);
inbox_post_link is a proposed/future API. Stop attributing the emulated
curator to the platform.
- Read isolation reframed around the outcome: no cap -> empty union read;
targeted read of an unheld repo -> RepoNotFound; cap introspection
(canRead/governsRead) is emulation-only with no NextGraph API behind it.
- read-model.md corrected: the listing path is per-doc ANCHORED default-graph
queries, never the anchorless GRAPH ?g union (that is O(wallet)); the probe
section no longer claims the opposite.
- README recap table restructured (target | current NextGraph status | current
emulation); INDEX_ACCOUNT documented as reservedAccount("index") in the
sentinel namespace; de-domained generic-layer comments; softened tone.
Consumer application (Festipod) rewired separately to own the relationship
concept and feed the lib an id. Lib gates: bun test 83 pass / 0 fail, tsc clean.

Inbox deposits and the per-(account,scope) index append were written into an
explicit GRAPH <plainNuri> named graph, which the real broker stores separately
from the repo's default graph (repo_graph_name with overlay suffix) — so an
anchored default-graph read (read-model.readDoc) never saw them and deposits
did not round-trip. Drop the GRAPH wrapper: the anchor scopes the write to the
repo's default graph, matching the read. Mocks updated accordingly.

loadShim() read EVERY account record in the shim (SELECT over the whole anchor
graph). On a shim that accumulates accounts (the shared wallet grows), that is
O(accounts) and hangs the hot path (~90s at ensureAccount → loadShim). Same
principle as per-doc reads: never scan a shared structure.
Add resolveAccount(username): a BOUNDED SELECT anchored on the single subject
accountSubject(username) → O(1), independent of account count. Cache in a
per-account Map (cleared by resetRegistryCache). Hot paths now use it:
ensureAccount (existence check), indexInboxNuri/@index (discovery), resolveInbox
Anchor, resolveWriteGraph, createEntityDoc, listMyEntityDocs. loadShim kept only
for genuine all-accounts needs (allAccounts, the listEntityDocs fan-out fallback).
The 90s ensureAccount/loadShim hang is gone. 93 tests pass; tsc rc=0.

- read-model.ts `readUnion` now applies the emulated ReadCap gate (drops a
subject when its doc is governsRead && !canRead for the current identity), so
per-scope isolation holds by construction AND by filter.
- store-registry: `listMyEntityDocs(username, scope)` (current account only) vs
the all-accounts `listEntityDocs` fallback (documented as the enumeration to
avoid on the read path).
- docs: nextgraph-current-state / read-model — corrected to the SOURCE-VERIFIED
reality that the JS SDK exposes NO open/sync-by-cap primitive
(load_repo_from_read_cap is pub(crate)); in the mono-wallet all repos are
already local (same session), so the anchorless union spans them with no open
step. simulation.md: listEntityDocs+useShape({graphs}) is a fallback, not the
read path.

Real-broker validation of the per-document model surfaced round-trip breaks the
fake-ng unit tests missed:
- The inbox anchor was the shim graph itself, making loadShim ~60s; give the
inbox its own document so anchor resolution is fast and isolated.
- store-registry adjustments so per-entity documents created via the SDK are
indexed and readable back through the scope fan-out.
docs/simulation.md updated. 89 tests pass; tsc rc=0.

The special discovery-index account was keyed as "@index", which the consumer's
normalizeUsername collapses to "index" — colliding with a real user named
"index" (who could then hijack/tamper the global index document). Introduce a
reserved-account namespace (a sentinel key unreachable by any typed username) so
the index account can never collide with user input. Test proves a user named
"index"/"@index" resolves to a DIFFERENT document than the reserved index
account. 80 tests pass; tsc rc=0.

Expose a clean scope-based surface so consumers work by scope (public/protected/
private) and never see a physical store id — the library resolves placement and
performs the shared-wallet simulation internally. RegistrySession gains optional
protected/public store ids, supplied at the single injection point
(configureStoreRegistry). Zero domain knowledge. docs/simulation.md updated.

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.

Port the shared-wallet shim mechanics from the Festipod app into the
generic @ng-eventually/client library — zero app-specific knowledge, the
consumer injects the domain (entity->scope mapping, connections, storage).
New namespaces exposed from src/index.ts:
- docs docCreate/sparqlUpdate/sparqlQuery via the REAL injected `ng`
(getConfig().ng), never the public makeNg proxy — the JS-over-
iframe double proxy breaks doc_create postMessage marshaling
(DataCloneError). Validated hard constraint.
- storeRegistry generic (account,scope)->NURI resolver, createEntityDoc/
listEntityDocs + per-scope index, sharedWalletShim in the
private_store, cache. Consumer wiring injected via
configureStoreRegistry({ getSession, normalizeUser }).
- isolation pure applyIsolation (public=all / protected=owner+connections
/ private=owner); accessors + connection graph injected.
- accounts AccountStore (localStorage-backed faux login, storage injected)
+ normalizeUsername. React wrapper intentionally NOT ported.
polyfill.ts gains configureStoreRegistry/getStoreRegistryDeps + resetConfig.
36/36 bun test, tsc --noEmit rc=0.
