S00-026: Verify pinned Linux runtime and isolated locked dependency access

Changes: Add a bounded reproducible HTTPS/checksum/runtime probe under environment-access, vendor checksums, unchanged parent manifest/lock copies, strict npm settings, result and reproduction notes. Record evidence and QA handoff; submit S00-026 without completing parent tasks.
Validation: Run verify.py twice successfully: vendor Linux archive SHA256 matched, Node 24.21.0/npm 11.19.0 executed, fresh-cache npm ci installed eight integrity-locked packages with scripts disabled, parent bytes stayed unchanged and Stanza import passed. tasks.py validate, git diff --check and scoped file whitespace checks passed. No browser/WSS, detached signature or provenance audit performed.

+# S00-026 review handoff
+
+Executor auto-ci-cd-4255c34da227 verified normal configured HTTPS access and
+isolated Linux x64 Node 24.21.0/npm 11.19.0 twice. Official archive checksum
+matched; unchanged copied parent lock installed eight packages with npm ci,
+strict TLS/engines and scripts disabled. Stanza 12.22.1 actual import passed.
+
+QA next: run python3 experiments/0002-xmpp-library/environment-access/verify.py
+from project root on Linux x86_64/Python with tarfile data filter, inspect the
+seven scoped files and state/evidence/S00-026-auto-ci-cd-4255c34da227.md.
+Compare copied manifest/lock to parent; verify fresh official checksum retrieval,
+exact versions, installed graph and no policy bypass. result.json records final
+runtime/cache paths under /tmp/luma-S00-026-gyx_1csp; they may expire, so repeat
+probe for independent evidence. node_modules is isolated and ignored.
+
+No separate owner statement about network restoration was supplied; actual
+approved configured HTTPS path works in this authorized network-enabled session.
+No network/system configuration changed, detached signatures/provenance audit,
+WSS/browser/product readiness verified, or original tasks completed. Separate
+review is required; executor stops on submit. Coordinator alone commits and
+launches the next fresh process.
