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. Docs: nextgraph-current-state (antagonisme + indirection),
simulation, migration-guide.

Dernière couche du bug de reconnexion : au cold-start, `watchShape` public +
protected + l'effet owned-events appellent `ensureAccount(A)` quasi-simultanément
AVANT la sync du shim → chacun lit 0 → chacun provisionne un nouveau jeu de docs
(fork par-appelant) → la résolution déterministe canonique fait alors diverger
lecteur et écrivain sur le docProtected → `readScopeIndex` vide.
Fix : `ensureInFlight` (map de promesses) dé-duplique les provisions concurrentes
en UNE seule ; `discovery.readIndex` ouvre son repo au cold-start (`ensureRepoOpen`).
Avec la résolution canonique déjà committée, écrivain et lecteur convergent.
Mesuré (levier isSuccess) : la participation protected converge `isSuccess=true,
data=1` sur la page fraîche (plus « vide à 30s »).
gate : tsc 0 ; bun test 123 ; test:e2e 42/42.

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.

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.

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.

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.
