S00-024: Verify restored pinned Linux XMPP environment access

Changes: Add the S00-024 continuation checkpoint, refresh verified runtime/cache paths, and replace the blocked handoff with QA and S00-020 restart instructions.
Validation: Existing verify.py passed official HTTPS/checksum retrieval, Node 24.21.0/npm 11.19.0, fresh-cache locked npm ci and Stanza import. Independent archive/input/version/config assertions, tasks.py validate and diff/scope/whitespace checks passed. Browser/WSS and product readiness remain unverified.

+On 2026-10-15 executor auto-ci-cd-49907d48a6d1 repeated the existing probe
+successfully after independent S00-026 acceptance. The interrupted environment
+restoration can now be reviewed: official HTTPS checksum/archive retrieval,
+Node v24.21.0/npm 11.19.0 execution, fresh-cache installation of eight unchanged
+parent locked packages and actual Stanza 12.22.1 import all passed. result.json
+contains this session's temporary paths. No probe implementation change was
+needed; S00-026 supplied the missing access and verification artifacts.

+After independent S00-024 review, a fresh S00-020 executor should rerun the
+command above, verify result.json and use its runtime_bin with an isolated cache
+within its own card. Host Node/npm are not the pinned runtime. Temporary paths
+can expire. This checkpoint does not install dependencies into the parent
+experiment or complete S00-020/S00-003; their own acceptance remains required.

+No exact product requirement is assigned to this remediation. No required input
+is missing. Initial git status showed only coordinator state/tasks.json claim.
+
+One output: current reproducible environment-access checkpoint and precise
+handoff, using the existing reviewed S00-026 implementation. Source diff only
+adds a continuation section to scoped README and refreshes result.json runtime/
+cache paths; no repair to probe code or partial source was needed. Prior handoff
+is superseded by the successful fresh run. No parent source/lock, accepted stack,
+shared interface, specs, network/system configuration or dependency changed.

+- python3 scripts/tasks.py resume --agent auto-ci-cd-49907d48a6d1: exit 0,

+- python3 experiments/0002-xmpp-library/environment-access/verify.py: exit 0.
+  Fresh official HTTPS SHASUMS256.txt and Linux x64 archive retrieval succeeded;
+  previous proxy DNS error did not reproduce through the configured route.
+  Archive SHA256 matched vendor fd8e59d5a511510f6a298afb548f18c7d2b1be404d8b4a27d94fbe49f56cb2d6
+  before tarfile data-filter extraction. Executing tools returned Node v24.21.0
+  and npm 11.19.0. Fresh-cache npm ci installed eight packages in 1s using
+  --ignore-scripts --strict-ssl=true --engine-strict=true, HTTPS registry,
+  no audit/fund, bounded timeout and no retries. Lock integrity retained.
+  Actual Stanza createClient ESM import passed.
+- Inline independent Python assertions: exit 0. Rehashed downloaded archive,
+  compared persisted/fresh vendor checksum bytes, copied/parent manifest and
+  lock bytes/hashes, all eight installed versions versus HTTPS/SHA512 lock
+  entries and actual Stanza 12.22.1. Pinned npm config get strict-ssl,

+
+## Acceptance / limitations
+
+The interruption has a preserved, runnable, reviewed prerequisite implementation
+and a fresh successful verification. S00-026 QA documents coordinator-approved
+configured HTTPS access. This executor did not bypass network/TLS/engine policy,
+select an alternate route, alter host tools, add secrets/real conversations or
+run Git mutations/other tasks/agents. Existing host tools are not used for npm ci.
+No product build, browser/WSS/client-server interoperability, detached signature,
+package provenance/advisory or release readiness check was run or claimed.
+Same-origin vendor HTTPS checksum is the bounded authenticity evidence.
+No tooling suite was needed for the unchanged probe implementation; validate and
+focused actual environment checks cover this card. Temporary paths can expire.
+
+QA must independently rerun the documented probe and inspect input hashes,
+checksum, strict settings and scoped diff. Approval only accepts S00-024 and
+allows a fresh S00-020 executor to continue through coordinator workflow;
+S00-020/S00-003 acceptance is not supplied here. Executor submits and exits;
+coordinator commits before the next fresh process.
