README: new section with a recap table (11 rows) — for each emulated behavior:
what the consumer sees (SDK-shaped API), how it's emulated on one shared wallet,
the real NextGraph target, and the lib-only migration. Makes "emulated ≠ real,
migration is a lib-only swap" explicit.
simulation.md: opening banner that EVERYTHING in the file is emulation pending
real NextGraph; corrected the stale read-path paragraph (per-doc anchored, never
an anchorless union-scan). read-model.md: reactivity bullet aligned to per-doc.

Add a diagram + prose to simulation.md: a virtual wallet = one shim account keyed
by a virtual-wallet id; it has the 3 native stores (public/protected/private) but
EMULATED — each "store" is an index document (AccountRecord.docPublic/Protected/
Private) listing that scope's per-entity doc NURIs. Everything physical lives in
the ONE shared wallet's private store; the 3-store structure is the per-account
logical layer. At migration the index docs become real native stores.

The anchorless union query (`GRAPH ?g`) scanned EVERY named graph in the local
store (the whole shared physical wallet) → O(wallet size), slow/timeouts on a
bloated wallet. Rewrite `readUnion` to run ONE ANCHORED `sparql_query` per by-need
doc (in parallel, per-doc tolerant): an anchored query is restricted to that
repo's graph, so it is O(1) per doc, INDEPENDENT of physical-wallet size. Keep the
ReadCap defense-in-depth gate.
docs/simulation.md: new "Physical wallet vs virtual wallet" section — the physical
shared wallet is a substrate that accumulates and must NEVER be enumerated/scanned;
each user's VIRTUAL wallet (the account's scope index in the shim) is the bounded
thing you enumerate ("list my documents"), then read those docs per-doc anchored.
read-model.md / nextgraph-current-state.md updated to the per-doc anchored rule.

- 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.

Proven against the real broker (probe): opening docs then a single anchorless
`sparql_query` with a `GRAPH ?g { ... }` body reads the LOCAL UNION of all synced
named graphs — the fast, hang-free replacement for the reactive-ORM per-document
fan-out (which aborted on any unsynced/fresh repo → 75s never-fires). New
`read-model.ts` (readUnion) exposes this; there is no reactive union query, so
listing is one-shot and consumers re-query on change. docs/read-model.md refined
with the probe finding (an explicit `GRAPH ?g` body iterates all named graphs
regardless of the anchor; the anchor only bounds the default graph). 93 tests
pass; tsc rc=0.

Source-verified against nextgraph-rs:
- nextgraph-current-state.md: NextGraph keeps ONE local oxigraph store per
session; each synced repo is a named graph. sparql_query with NO anchor
(UserSite/None) queries the UNION of all synced graphs (set_default_graph_as
_union); with an anchor it is restricted to one repo. Union is read-only
(updates need a doc anchor). No reactive SPARQL (one-shot). Root cause of the
ORM fan-out hang: orm_start_graph opens every graph in scope; a fresh/unsynced
per-entity doc → RepoNotFound aborts the subscription → the 75s never-fires.
- read-model.md (new): the read model — events via the global index (the one
enumeration hack); everything else by following a shared graph, opened/synced,
then listed via a single anchorless union sparql_query (never the ORM per-doc
fan-out); reactivity via re-query on a doc_subscribe/ORM change signal. Plus
the minimal broker probe to confirm the union behavior.

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 ReadCap filter now enforces on per-entity documents (consumers create one doc
per entity, so each has a declared policy — private→owner, protected→owner+
connections, public→all). Isolation is genuinely active, not dormant.
- connections.ts (new): a BILATERAL connection registry — a link grants protected
read only when BOTH sides have asserted it (each assertion bound to its author).
A unilateral/self-declared connection grants nothing (closes the confused-deputy
hole). declareConnections is authenticated to the current identity.
- inbox.post: `from` is bound to the current identity — a spoofed `from` throws.
- discovery.submitToIndex: PUBLIC-ONLY — a governed non-public doc is refused
(no protected/private leak into the world-readable index).
- docs/simulation.md: documents this as application-level emulated isolation on a
shared wallet (not crypto); at NextGraph maturity → real caps, consumer unchanged.
89 tests pass (+10 covering: active protected isolation via bilateral connect,
unilateral grants nothing, from-spoof rejected, non-public submit refused). 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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add a generic discovery-index surface: submitToIndex(ref) deposits a reference
into the index document's inbox; readIndex() returns the materialized entries. A
reserved special account (@index) owns the index document; deposits flow through
the emulated inbox and are materialized by the emulated curator (the dedup/
moderation point). This replaces cross-account fan-out as the discovery path and
is more faithful to the target (a single owned index fed via its inbox). Generic
(the consumer supplies the reference to index). 79 tests pass; tsc rc=0.

Isolation was dormant (no current identity ever set). Now: setCurrentUser
records who is reading; declareConnections(neighborsOf) grants each protected
document's read cap to owner + connections. Reads discriminate through the
ReadCap filter: private→owner, protected→owner+connections, public→all. Generic
(the consumer injects identity + connections). Write-guard coverage limits
documented honestly in docs/simulation.md (real write paths bypass the JS proxy;
full enforcement awaits native caps). isolation-active.test.ts proves the
protected+connections path.

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.

This library presents a mature-NextGraph SDK face to consumers while
compensating for the current SDK's gaps via a shared-wallet simulation. It
therefore OWNS all current-state + simulation knowledge — moved here out of the
Festipod app repo, which must treat this library as a finished SDK.
New docs/:
- nextgraph-current-state.md — what the current SDK/broker do and don't expose
(5 store types, document=repo, per-document ReadCap, inbox not exposed, iframe
RPC proxy, mono-user/no-global-data, wallet import constraint). Keeps the
nextgraph-rs source pointers.
- simulation.md — how the lib emulates the mature behaviour on one shared wallet
(shim, store!=document two axes, docCreate→private store, RepoNotFound scope
rule, @ng-org double-proxy DataCloneError, emulated ReadCap/inbox/curator).
- decisions/ — the current-SDK ADRs (private-store-nuri-scope, sparql-delete,
shared-wallet-login, discovery mechanism).
- fork-inbox-fallback.md — the Rust-patch/self-host route not taken.
- migration-guide.md — the checklist for when real NextGraph matures.
README: boundary framing from the lib's side + docs/ index; replaced the stale
"scaffold/stubbed" status with the actually-implemented mechanisms per source.

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.

Model the read filter on NextGraph's real ReadCap mechanism instead of an
invented per-item grant. Verified in nextgraph-rs: there is no Document type
(document = repo); a store is a container repo referencing other repos by RDF
overlay; holding a store's cap does NOT grant the repos it contains (each repo
needs its own cap; no read-cap inheritance). So the access unit is the
DOCUMENT = an item's `@graph`, never the item.
- caps.ts: CapRegistry (read/write caps per document NURI + public docs;
open/grantRead/grantWrite/makePublic/canRead/canWrite/governsRead/
hasReadPolicy). Replaces access.ts (Grant).
- read-filter.ts: filter keeps an item iff its `@graph` document is readable
(held cap or public); items with no `@graph` or in an ungoverned document are
kept. No injected grantOf — the filter reads `@graph` and consults the
registry (automatic, domain-agnostic).
- polyfill.ts: getCaps()/resetCaps() replace setGrantOf/getGrantOf; useShape
filters only when caps.hasReadPolicy() (else passthrough, no regression).
- tests: caps.test.ts (6) + read-filter.test.ts (4), incl. no-inheritance
between documents. 10 pass; tsc rc=0.

makeReadFilteredView wraps a DeepSignalSet in a Proxy whose iteration/size/forEach
yield only items the current user may read (canRead on the item's emulated grant), while
add/delete and the underlying reactivity pass through. filterReadable is the pure core.
useShape applies it only when a grantOf resolver is configured (else passthrough, so
ungranted apps are unaffected). grantOf/setGrantOf added to the polyfill surface. Mirrors
the broker delivering only authorized docs; removed at migration. 4 unit tests.

lifecycle.ts forwards init (@ng-org/web) and initNg (@ng-org/orm) to the injected
SDK; index re-exports the SDK types (ShapeType, BaseType, Schema, DeepSignalSet, NG) so
consumers import everything from @ng-eventually/client. Type re-exports are erased at
build → no runtime @ng-org import added (no duplicate SDK copy). @ng-org added as
devDependencies (typecheck only) + peerDependencies. EventuallyConfig accepts init/initNg.
Typecheck + 4 tests green.

Generic polyfill layer that makes a single NextGraph broker behave like the
not-yet-shipped multi-user NextGraph (emulated capabilities + inbox). Zero app domain.
@ng-eventually/client exposes an SDK-identical surface (ng, useShape, inbox); the
polyfill bootstrap (configure + capability helpers) is isolated under /polyfill, so
the main entry stays a drop-in for @ng-org/web|orm. The real SDK is injected at
configure() (no hard import → build-alias safe + testable).
Scaffold: NextGraph wiring stubbed with TODO; capability helpers implemented and
unit-tested (4 tests, typecheck clean). The global-index curator is deferred — in
NextGraph apps/services are mono-user with no global data.
