Les 25 modules étaient à plat, nommés d'après ce qu'ils font mécaniquement
(`store-registry`, `read-model`, `reach`, `caps`). Rien dans l'arborescence ne
disait lesquels DEVIENDRONT le vrai SDK, lesquels tiennent lieu du travail que
le verifier fera nativement, et lesquels n'existent que parce qu'un wallet est
partagé — trois destins sans rapport.
Quatre dossiers, les deux fichiers d'entrée restant à la racine pour que
l'`exports` du paquet et le code du consommateur ne bougent pas :
- `model/` — le modèle d'adressage de la cible, transcrit : vocabulaire pur,
pas d'I/O. Survit comme connaissance.
- `surface/` — ce que l'app touche, chaque symbole ayant un pendant cible
documenté. Supprimé quand l'alias bascule ; le code de l'app est inchangé.
- `emulated-verifier/` — les doublures de ce que le verifier fait nativement :
possession, dépôt des caps, frontière, non-livraison, traitement des inbox,
registres de branche, ouverture de repo. **C'est le dossier où diverger du
modèle est possible.** Le préfixe `emulated-` porte le sens : tient lieu de,
jamais est — cette bibliothèque ne réside dans aucune couche de la cible,
elle les référence.
- `shared-wallet/` — n'existe que parce qu'un wallet héberge toutes les
identités. Aucun pendant, rien sur quoi s'aligner ; sa seule loi est de
rester invisible depuis `surface/`. S'évapore, remplacé par rien.
`store-registry-api.ts` devient `surface/placement.ts` : il faisait déjà à la
main ce que la frontière de dossier fait structurellement — c'est la meilleure
preuve interne du bien-fondé de ce rangement.
Ce commit ne fait que déplacer et recâbler les imports (src, test, e2e). Les
scissions des modules à cheval suivent.
157 tests unitaires, typecheck src/test/e2e vert.
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.
