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.

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.

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.
