Changes: Preserve incomplete work and blocker metadata for S00-004. This checkpoint does not mark implementation accepted. Validation: Session ended with status blocked. Blocker: S00-004 acceptance requires establishing legacy/OMEMO2 AND worker/wasm AND persistence without a homegrown ratchet. Reproduced (this run) probes and live public-registry queries confirm only the audited session/ratchet engine + persistence are verified (@signalapp/libsignal-client@0.105.0, Node native addon, zero .wasm). The browser/worker/WASM deployment and the OMEMO/OMEMO2 wire layer are not available from any maintained package on the reachable registry (@signalapp/libsignal, @converse/omemo, @xmpp/omemo, omemo2, omemo-js, omemo-client, omemo-top, omemo-wasm all E404). ENC-009 forbids a homegrown algorithm/ratchet and ENC-011 forbids substituting media AES-GCM for the OMEMO2 wire format, so the spike cannot synthesize a browser backend inside S00-004 scope.

Один результат
One independently reviewed, traceable primary-source outcome that establishes a verified browser/worker/WASM-capable OMEMO2 backend (a maintained library with a real web/WASM build and an OMEMO2/S ce-format mapping, or an approved external library/provider decision with license + support + browser constraints), preserving the verified audited session/ratchet engine and persistence from the existing spike, without a homegrown ratchet or ENC-009/ENC-011 bypass.

Шаги
- Read S00-004 blocker evidence, ADR 0003, and accepted ENC-003/ENC-009/ENC-011 with ADRs 0000-0002.
- Confirm the residual browser/worker/WASM OMEMO2 backend is unavailable from any maintained package on the reachable registry (reproduce wasm-unsupported probe and npm view queries).
- Source or confirm a maintained browser/worker/WASM-capable OMEMO2 encryption layer: verify its web/WASM build, license, primary-source docs, support, and an OMEMO2 wire mapping against ENC-011; or record the concrete external product/administrative decision (library, provider, or license acceptance) required to bring such a backend in.
- Run a focused known-answer OMEMO2 roundtrip in the web-compatible target and record actual results (or record an unsupported format blocker, not success) and update docs/decisions/0003-crypto-library.md; submit evidence and handoff for independent security review.
Приёмка
- A browser/worker/WASM-capable OMEMO2 backend is established with a real, verified web build and an OMEMO2 wire mapping from traceable primary sources, or an explicit external decision (with specific requested input) is recorded that unblocks sourcing it.
- The OMEMO2 wire-format mapping does not bypass ENC-009/ENC-011 client-endpoint encryption.
- No homegrown ratchet, no spec/plan/shared-contract change without plan, no secrets in evidence, and no out-of-scope edits; unsupported format recorded as blocker, not success.
Focused checks
- Known-answer OMEMO2 roundtrip in the web/WASM target, or a traceable upstream/external decision covering ENC-009/ENC-011.
- Web/WASM asset presence verified (non-zero real footprint), license and support checked.
- Independent security review confirms no bypass and no unsupported format counted as success.
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.
