# S00-003 blocked handoff

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

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.

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.

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 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.
