wt ca20031bf9 S00-026: Approve pinned Linux artifact access after independent verification
Changes: Accept the bounded S00-026 access probe; add independent QA evidence and refresh successful result runtime/cache paths. Preserve parent task incompleteness.
Validation: Repeat verify.py successfully with fresh official HTTPS downloads, matching vendor SHA256, exact Node 24.21.0/npm 11.19.0, eight locked packages and actual Stanza import. Independently check copied input bytes, installed versions, integrity and strict npm settings. tasks.py validate and git diff --check pass. Inspect executor patch/message and coordinator access confirmation. Browser/WSS and detached signature/provenance audits remain outside this review.

S00-026 Linux environment access probe

Normal configured HTTPS access, authorized by the assigned environment-access probe and this session's enabled network, succeeded on 2026-10-15. The previous configured-proxy DNS failure did not reproduce. No proxy/environment/system configuration was changed and no alternate network route was selected. No separate environment-owner connectivity statement was supplied; the evidence is actual access through the existing configured path, not an assertion about an administrator's network changes.

Run from the project root on Linux x86_64 with Python supporting tarfile's data extraction filter (Python 3.12+ recommended), curl and xz support:

python3 experiments/0002-xmpp-library/environment-access/verify.py

The probe retrieves the official Node 24.21.0 Linux x64 archive and vendor SHASUMS256.txt through verified HTTPS. It checks SHA256 before safe extraction into a fresh /tmp/luma-S00-026-* directory, executes exact Node 24.21.0 and npm 11.19.0, and installs byte-identical parent manifest/lock copies here using npm ci --ignore-scripts --strict-ssl=true --engine-strict=true with a fresh isolated cache. All eight locked dependencies retain HTTPS registry URLs and SHA512 integrity. It checks every installed version, unchanged manifest/lock bytes and a real Stanza createClient import. Any command/check failure exits unsuccessfully; result.json records the last successful run only.

SHASUMS256.txt preserves retrieved vendor checksum material; result.json records the verified archive hash, input hashes and temporary paths. Reviewer should repeat the probe with fresh retrieval, rather than trust these reports. The runtime/archive/cache remain temporary, node_modules is Git-ignored, and no system installation is performed. These paths are available to later local sessions until temporary storage is removed; rerun the probe if absent.

No TLS/proxy/engine bypass, dependency additions, stack/lock/spec modification, credentials, real messages, npm lifecycle scripts or Git mutations. The copied parent graph was already inspected in prior experiment tasks; this probe adds no dependency or library-selection decision. Node/npm retain their distribution license files; dependency notices remain in the existing experiment inventories.

Checksum verification trusts the vendor HTTPS origin; no detached signature, package provenance/advisory audit, browser/WSS authentication, application build or interoperability claim is made. This outcome is submitted for independent QA review only. S00-020, S00-024 and S00-003 remain unfinished; this executor does not continue their work or change their statuses directly.
