Changes: Add an isolated pinned mechanism wrapper using Stanza's public constructor and factory APIs, preserve the SCRAM-SHA-512 wire name and fail-closed final guard, and document the proposed ADR, browser bundle evidence, independent Scramp vectors, notices and limits. Leave parent selection, dependency experiments, specs and shared contracts unchanged. Validation: Fresh-cache npm ci and Vite browser build pass; 87 focused tests pass, including RFC HMAC vectors, original defect reproduction, independent full SHA-512 exchanges and rejected invalid finals/order/reset paths. Hashed Scramp oracle fixture comparison passes. Dependency check verifies 49 locked entries, 25 installed pins/licenses and 340 unmodified Stanza files. make check passes 72 tooling tests. Native browsers, WSS/live server interoperability and production readiness are untested; independent security review remains pending.

ADR
Статусы: proposed, accepted, superseded. У каждого решения: вопрос, варианты, primary sources с датой, runnable spike/проверка, лицензия, browser constraints, выбранный вариант, последствия, reviewer и связанные tasks. Сейчас ни framework, ни crypto/XMPP library не объявлены принятыми.
