Changes: Preserve incomplete work and blocker metadata for S00-003. This checkpoint does not mark implementation accepted. Validation: Session ended with status blocked. Blocker: Stanza 12.22.1 browser HMAC sha-512 fails RFC 4231 Test Case 1: wrong 64-byte block selection. SCRAM-SHA-512 derives that hyphenated algorithm; private algorithm mutation/vendor patches are unsupported. Parent cannot attest browser strongest-mechanism compatibility from Node-only success. Task: S00-003 Agent: auto-protocol-dcdf92cd067e Role: protocol Action: claim Status: blocked Task title: Проверить XMPP WSS/auth библиотеку

Один результат
One isolated runnable independently reviewed browser-compatible SCRAM-SHA-512 integration uses vetted existing crypto through a supported public mechanism API and validates proof/server-final without vendor/private-field patching or custom primitives.

Шаги
- Read original blocker, accepted stack/SASL ADR and pinned browser implementation/public APIs.
- Reproduce the HMAC alias defect and evaluate an existing vetted mechanism/backend or candidate with primary docs, exact pins, license and browser/API checks.
- Implement only isolated SCRAM-SHA-512 integration via supported public APIs using existing cryptographic code; retain fail-closed mutual authentication and real absence of channel binding.
- Run fixed known vectors and full exchange positive/negative checks against the browser-resolved backend; preserve evidence, limitations and handoff for independent security review.
Приёмка
- RFC SHA-512 known vectors match using actual browser-compatible crypto backend, including algorithm spelling and varied key lengths.
- Full SCRAM-SHA-512 client proof and verified server-final agree with an independent existing implementation/fixed externally derived vector; missing/forged/premature final fails without authentication/restart.
- Integration uses public mechanism APIs, correct SCRAM-SHA-512 wire name, no private-field/vendor patch, invented binding, custom primitives or plaintext downgrade.
- Runnable pinned fixture experiment and browser bundle/backend evidence permit independent review; no parent WSS/library selection/shared contract work.
Focused checks
- Reproduce original browser sha-512 HMAC mismatch.
- Fixed SHA-512/HMAC known vectors including long keys using selected browser backend.
- Full SCRAM-SHA-512 verified exchange and forged/missing/out-of-order server-final rejection.
- Exact dependency/license/API/browser checks and repeatable clean install/bundle plus focused suite.
Блокер и завершение запуска
Для всех ролей scope — только эта задача. При блокере создать issue JSON по state/ISSUE_TEMPLATE.json, вызвать escalate с текущим ID/role/agent, проверить status=blocked и resolution_task, затем немедленно завершить запуск. Не решать blocker и не выбирать следующую задачу самому. Новый агент назначается runner. Правки metadata через CLI — единственное исключение scope.
Передача
Сохранить evidence/handoff; submit → review и завершить запуск. Reviewer также выполняет только эту задачу, включая обязательное escalate при блокере.
