Two batches, verified against nextgraph-rs throughout.
P1a — the capability surface. Reading was an ACL (Map<doc, Set<principal>>),
the exact inversion of key possession. It is now possession: `capFor(nuri)` is
the only question, there is no principal parameter anywhere, and nothing turns
a bare reference into a cap. Sharing is `shareCap(cap, toInbox)`, a Link
deposit; receiving needs no operation. `Nuri` and `ReadCap` are template
literal types, so passing a bare reference where a cap belongs is a compile
error, with runtime guards behind it for JavaScript callers.
The virtual user boundary. Every access function is now confined to the
connected user, through two rules on one criterion (possession), implemented in
two places so a lapse in either is caught by the other: authorization at the
passage points, and "do not even attempt" at the callers. The polyfill's own
machinery moved to physical.ts — unguarded, never exported — which replaced an
exemption list: the machinery no longer gets waved through the guard, it calls
something the guard never saw.
Removed, as emulating capabilities the target does not have:
- discovery.ts and its global index. There is no discovery in NextGraph; you
follow links. It also pooled user data across wallets.
- the cross-account fan-out (listEntityDocs, resolveReadGraphs, allAccounts,
loadShim), which was cross-user enumeration by construction.
- resolveInboxAnchor, a single inbox common to every user.
Caps are now stored where NextGraph stores them, and read back rather than
recomputed: AddRepo on the store's Store branch for documents a user creates,
AddLink on its User branch for caps received. Inboxes belong to someone — the
user's own, plus one per document — and connecting a user drains them all;
that is the library's job, not the app's.
Corrections worth recording: a ReadCap is `r:`, not `:k:` (reported by
NextGraph's developer, verified in BlockRef::readcap_nuri); received caps DO
have a register (AddLink), contrary to what this repo's notes claimed; and
"wallet" upstream means keyring — what owns three stores is a user, so the
vocabulary follows.
The cap value is the constant OK: the only question the emulation answers is
whether a cap is held. P1b replaces that one constant with a real key.
After this the shape is right and the isolation is still fake. Nothing here may
be described as anonymous or private.
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.

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.

Expose subscribeDoc(nuri, onChange) / subscribeDocs(nuris, onChange) wrapping the
real ng.doc_subscribe — per-document, event-driven (initial State + a Patch per
commit, local or broker-synced from a remote peer), returning a sync unsubscribe.
subscribeDocs isolates per doc (a failing/unsynced doc never aborts the others),
so it sidesteps the ORM fan-out hang (never orm_start_graph(graphs:[…])).
Replace the setInterval polling in inbox.watch() and discovery.watchIndex() with
doc_subscribe — same public contract, now push not poll. NextGraph is subscription-
first; no polling remains.
Verified against the real broker (@data harness spike): the doc_subscribe callback
marshals across the iframe RPC (@ng-org/web strips the callback and drives it via a
MessagePort — no DataCloneError) and fires on the initial push and on a real write.
Lib bun test 91 pass, 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.

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.

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.
