S00-024: Record blocked task and remediation handoff

Changes: Preserve incomplete work and blocker metadata for S00-024. This checkpoint does not mark implementation accepted.
Validation: Session ended with status blocked.
Blocker: S00-024 cannot establish readiness for S00-020: official checksum retrieval fails with configured proxy DNS error and host Node/npm differ from accepted pins; no partial environment-access artifacts exist.

Task: S00-024
Agent: auto-ci-cd-988167c541cf
Role: ci-cd
Action: claim
Status: blocked

Task title: Устранить прерывание: Restore access to the pinned Linux XMPP experiment toolchain

+## One remediation outcome
+
+One independently verified approved access path supplies authentic pinned Linux Node/npm and integrity-verifiable parent locked dependencies for S00-020.
+
+## Evidence / reproduction
+
+node --version: v24.1.0; npm --version: 11.3.0. Official HTTPS SHASUMS256.txt curl exits 5, Could not resolve proxy. See state/evidence/S00-024-auto-ci-cd-988167c541cf.md.

+The reporting agent must stop now. A new agent implements only S00-026.

+Input: assigned interruption remediation, original blocker/handoff, accepted stack
+and SASL/parser/SHA512 ADRs, direct dependency evidence, required startup/role/testing
+instructions. Output sought: verify preserved partial work and readiness for a fresh
+S00-020 executor. No task requirements or stack changes are authorized.

+## Actual commands and results

+- python3 scripts/tasks.py resume --agent auto-ci-cd-988167c541cf: exit 0,

+- python3 scripts/tasks.py show S00-024: exit 0; scope/dependencies confirmed.
+- git status --short: exit 0; only coordinator state/tasks.json claim modified.
+- ls -la experiments/0002-xmpp-library/environment-access: failed, directory absent.

+  was followed by other commands in the shell; overall shell exit is not the ls exit.

+  https://nodejs.org/dist/v24.21.0/SHASUMS256.txt
+  -o /tmp/luma-S00-024-SHASUMS256.txt: exit 5,
+  Could not resolve proxy: proxy.micran.ru.
+
+## Result and limits
+
+Accepted ADR 0001 requires Node 24.21.0/npm 11.19.0. The original environment
+failure remains reproducible; normal configured HTTPS cannot retrieve vendor
+checksums. No source edits, runtime/dependency installation, policy changes,
+TLS/proxy/engine bypass, build, tests, browser/WSS execution or success claim.
+No secrets or real messages are recorded. This session cannot prove S00-020 ready.
+One external remediation requests approved access or authentic local artifacts;
+only a new executor can verify them after release. No Git mutation or agent launch.

+Assigned executor: auto-ci-cd-988167c541cf (ci-cd).
+No partial source directory exists at experiments/0002-xmpp-library/environment-access.
+No source changes were made. The configured HTTPS checksum retrieval still fails
+with curl exit 5 (proxy DNS); host Node/npm are 24.1.0/11.3.0 instead of
+accepted 24.21.0/11.19.0. Evidence: state/evidence/S00-024-auto-ci-cd-988167c541cf.md.
+
+Next input: environment owner must provide approved configured HTTPS connectivity
+to official Node distribution and locked npm registry URLs, or authentic Linux
+Node 24.21.0 archive with trusted vendor checksum material and an integrity-verifiable
+cache of the unchanged parent lock graph. Provide paths/access confirmation only,
+never credentials. A new bounded executor must verify exact versions/checksums and
+isolated copied-manifest npm ci with scripts disabled and TLS verification retained.
+Do not declare S00-020 or S00-003 complete. Reporter exits after escalation.
