S00-003: Record blocked task and remediation handoff

Changes: Preserve incomplete work and blocker metadata for S00-003. This checkpoint does not mark implementation accepted. Validation: Session ended with status blocked. Blocker: S00-003 cannot reproduce accepted Node 24.21.0/npm 11.19.0 or install locked Stanza: host tools are 24.1.0/11.3.0, parent node_modules is absent, and normal official HTTPS retrieval fails with unresolved configured proxy. Task: S00-003 Agent: auto-protocol-59f4d359b339 Role: protocol Action: claim Status: blocked Task title: Проверить XMPP WSS/auth библиотеку

+3. Работать только над одним указанным outcome. Если для него нужен новый shared contract — создать отдельную remediation через escalate, заблокировать original и завершить запуск; не расширять текущий scope.

 # S00-003 blocked handoff

-Executor: auto-protocol-dcdf92cd067e, protocol, 2026-10-15.
+Executor: auto-protocol-59f4d359b339, protocol, 2026-10-15.
 Outcome remains library selection with WSS/auth/parser/extension spike.

-Accepted prerequisites: S00-001 scope, S00-002 stack, S00-017 fail-closed SASL
-and S00-018 bounded parser ingress. Their ADRs/evidence were read; their suites
-were not rerun or changed. Parent Stanza candidate remains unselected, parent
-exploratory manifest/lock incomplete, selection ADR absent.
+Accepted prerequisites S00-001/002/017/018/019 were read. The SHA-512 public
+mechanism composition is now independently accepted; the earlier crypto blocker
+is resolved. Their suites were not rerun in this environment. Parent candidate
+remains unselected and selection ADR absent.

-Blocker newly reproduced in pinned Stanza 12.22.1 browser crypto:
-createHmac('sha-512', RFC 4231 section 4.2 key/data) returns a different digest
-than the fixed primary-spec vector and Node native crypto. sha512 alias and
-sha-256/sha-1 controls match. Browser Hmac tests only alg === 'sha512' for its
-128-byte block size, while SCRAM-SHA-512 derives 'sha-512'; that SCRAM field
-is private in declarations. Direct browser module execution in Node is a
-backend diagnostic, not actual browser/WSS execution. Exact reproduction and
-digests: state/evidence/S00-003-auto-protocol-dcdf92cd067e.md.
+Current blocker: accepted Node 24.21.0/npm 11.19.0 and installed Stanza are not
+available in this Linux session (host tools 24.1.0/11.3.0; parent node_modules
+absent). Official checksum retrieval over configured HTTPS fails with curl exit
+5, unresolved proxy. See state/evidence/S00-003-auto-protocol-59f4d359b339.md for exact reproduction.

-Source edits stopped; none were made. Do not patch ignored vendor code/private
-fields, implement primitives, change wire name, claim successful SHA-512 from
-Node-only crypto or silently downgrade to avoid the defect. One fresh crypto
-resolver must produce an isolated browser-compatible SCRAM-SHA-512 integration
-using vetted existing crypto and supported public mechanism extension APIs,
-with known vectors, full proof/server-final and negative tests. Independent
-security review must accept that outcome before coordinator resumes original.
+Next input: external environment owner must restore approved HTTPS access to
+nodejs.org and registry.npmjs.org or provide authentic, checksum/integrity-
+verifiable pinned Linux toolchain and locked package artifacts through an
+approved local path. Do not change stack pins, bypass proxy policy/TLS, fabricate
+engine metadata or reuse a macOS binary. Fresh remediation executor must verify
+exact runtime and lock installation, with independent review before parent
+returns to a new executor. Supply no credentials in committed evidence.

-No WSS handshake, browser build/runtime, complete mechanism policy, extension
-roundtrip, selection or independent interoperability has been completed in this
-session. No clean install/make check claimed. No shared/spec/accepted dependency
-changes. Reporter exits immediately after escalate and cannot implement resolver,
-unblock/reclaim or launch another process.
+No source changes or installs/build/tests/browser/WSS execution occurred. Browser
+binaries are present but not exercised. No make check, complete SASL policy,
+extension roundtrip, independent interoperability or selection claimed.
+Reporter exits after escalation; no resolver work, unblock or new agent launch.
