S00-024: Approve restored Linux toolchain continuation checkpoint

Changes: Accept the bounded S00-024 restoration checkpoint, add independent QA evidence and handoff, and refresh successful probe runtime/cache paths.
Validation: Independently reran verify.py with official HTTPS checksum, Node 24.21.0/npm 11.19.0, fresh-cache locked npm ci and Stanza import; archive/input/installed-version/strict-config assertions, tasks.py validate and diff/scope/whitespace checks passed. Browser/WSS, interoperability and product readiness remain unverified.

Task: S00-024
Agent: auto-qa-e19cd93db255
Role: qa
Action: review
Status: done

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

+# S00-024 independent QA review
+
+Reviewer: auto-qa-e19cd93db255 (qa), 2026-10-15.
+Executor: auto-ci-cd-49907d48a6d1. Decision: approve bounded continuation checkpoint.
+
+Input: master/AGENTS/README/common/qa, profile/architecture/contracts/workflow/
+automation/Git instructions; resume/show/card/packet/handoff, required TESTING,
+protocol, decisions README and blockers S00-020/024; accepted scope/stack/SASL/
+parser/SHA512 ADRs and direct dependency executor evidence, S00-026 independent
+review and handoff. No exact product requirement or shared contract is assigned.
+Output: independent review evidence and handoff note, fresh successful result
+paths, reviewer commit message and approval transition for S00-024 only.
+
+## Patch review
+
+Read git log --all --oneline --grep='^S00-024:', current executor commit
+4bad1f228e07cd882dc023d33d2bb31b7afaf71b and prior blocked checkpoint 6f0b402.
+Current source diff only adds a README continuation checkpoint and refreshes two
+temporary result paths under environment-access/**. Remaining changes are
+workflow metadata/generated status. Executor message matches actual diff and
+bounded checks. Probe implementation and parent dependency graph remain unchanged.
+Initial git status was clean. Prior blocker recorded absent artifacts and proxy
+DNS failure; independently accepted S00-026 supplied the artifacts/access.
+The S00-026 review records coordinator-approved configured HTTPS access. No
+network/system configuration or alternate route was changed during this review.
+
+## Actual commands and results
+
+- python3 scripts/tasks.py resume --agent auto-qa-e19cd93db255: exit 0, [];
+  reviewer did not claim executor work.
+- python3 scripts/tasks.py show S00-024 and packet S00-024 --agent
+  auto-qa-e19cd93db255: exit 0 each; review state, scope and done dependencies.
+- python3 experiments/0002-xmpp-library/environment-access/verify.py: exit 0.
+  Fresh official HTTPS checksum/archive retrieval succeeded without proxy/TLS
+  bypass. Vendor SHA256 matched before tarfile data-filter extraction:
+  fd8e59d5a511510f6a298afb548f18c7d2b1be404d8b4a27d94fbe49f56cb2d6.
+  Executing tools returned Node v24.21.0/npm 11.19.0. Fresh-cache npm ci installed
+  eight packages in 3s with scripts disabled, strict SSL/engines, HTTPS registry,
+  SHA512 lock integrity, bounded fetch timeout and no retries. Actual Stanza
+  createClient ESM import passed.
+- Independent inline Python assertions: exit 0. Rehashed actual downloaded
+  archive against result and vendor checksum, compared fresh/persisted checksum
+  bytes; copied manifest/lock equal parent bytes and recorded SHA256. All eight
+  installed versions match HTTPS/SHA512 lock entries; actual Stanza is 12.22.1.
+  Re-executed exact node/npm version commands. Pinned npm config get strict-ssl,
+  engine-strict and ignore-scripts each returned true; inherited
+  NODE_TLS_REJECT_UNAUTHORIZED is not 0. Python 3.14.7, Linux x86_64.
+- python3 scripts/tasks.py validate: exit 0; 293 tasks, 22 stages,
+  221 requirements, 211 allocated Web requirements, revision 82.
+- git diff --check, git diff --stat, git status --short --untracked-files=all:
+  exit 0 each; after probe only scoped result.json runtime/cache values changed.
+  Final authored metadata whitespace and changed-path scope assertions: exit 0.

+Review runtime: /tmp/luma-S00-026-mil9mnes/node-v24.21.0-linux-x64/bin.

+Parent manifest SHA256: e0ffb0c94e198e26f8e44e9b22ff4e121760d9f1197ed7bd5a90e1b4bb112766.
+Parent lock SHA256: 9c85ad62721eb2deacb298f29fa2bae211a29c964707d52c2dfbf8614b7dbb05.
+
+## Acceptance and limitations
+
+1. Pass: interruption/access cause no longer reproduces. Preserved reviewed
+   probe runs successfully in this fresh independent session, enabling a new
+   S00-020 executor to continue through coordinator workflow.
+2. Pass: no original acceptance bypass. S00-020 and S00-003 remain unfinished;
+   no parent lock, spec, stack, shared interface or production module changed.
+
+Authenticity evidence is same-origin vendor HTTPS checksum, without detached
+signature verification. No package provenance/advisory audit, browser execution,
+WSS/server/client interoperability, app build or release readiness was checked
+or claimed. Tooling suite was not run for this unchanged probe; focused actual
+access/install checks and plan validation cover the assigned outcome. Temporary
+runtime/cache may expire; rerun verify.py and use current result.json. Coordinator
+commits review before fresh S00-020 work. No Git mutation, other task selection
+or agent launch; this reviewer exits immediately after approve.

+## Independent QA continuation note
+
+Reviewer auto-qa-e19cd93db255 independently repeated verify.py successfully;
+see state/evidence/S00-024-review.md. Current result.json points to

+Checksum, unchanged parent inputs, all eight installed versions and strict

+continuation checkpoint. Coordinator commits before a fresh S00-020 executor;
+S00-020/S00-003 acceptance and all browser/WSS/interoperability work remain.
+Temporary paths can expire; rerun the scoped probe when needed.
