Consumer-side of the @ng-eventually/client fidelity pass, plus the identifier UX: - Identity: the user types an IDENTIFIER at the access barrier (AccessGateScreen), in the same act that opens the shared wallet — the separate 'pick a username' screen (ConnexionScreen) is removed. The identifier is a technical id (a pseudo in practice, not a Festipod username), normalized (trim, @-stripped, lowercased) and persisted before the broker redirect, then handed to the SDK as the identity. AccountContext keeps its API but its stored value is now this normalized id. - Relationship/connections are app-owned: new src/shared/utils/connections.ts holds the bilateral registry and maps each link to the SDK's directed grantRead(doc, grantee); the lib no longer carries a connection concept. Rewired FestipodData and the @data harness to it. - Login removed: accounts use the SDK's IdentityStore (set/clear/get); no faux login/logout framing in the SDK boundary. Doctrine reconciled: app-security (knowledge_authentication flow, knowledge_trust-model directed grants, decision_2026-07-06_identifier-at-access-barrier), data-layer (knowledge_context-internals: stable id principal + single-seed), app-architecture (knowledge_screens auth inventory), bdd-testing (caveat_wallet-bloat-hang). App gates: tsc no new errors, build OK. @data path unaffected (harness bypasses the gate and sets identity directly; login() is not on that path).
