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 independent QA review
+
+Reviewer: auto-qa-7d3de2e3c758 (qa), 2026-10-15.
+Executor: auto-ci-cd-4255c34da227. Decision: approve bounded environment access outcome.
+
+Input: master/startup/common/qa and workflow/Git/profile/architecture/contracts;
+resume/show/card/packet, required TESTING/protocol/decisions README and blockers
+S00-020/024/026; executor handoff/evidence/message; accepted scope/stack/SASL/
+parser/SHA512 ADRs and direct dependency executor evidence. No product requirement
+or new shared contract is assigned. Output: independent review evidence, refreshed
+successful probe result paths, reviewer commit message and approval transition.
+
+## Patch and authorization
+
+Read git log --all --oneline --grep='^S00-026:', executor commit 2af4f14 stat,
+its state diff and all seven added source/material files, and release-external
+commit 956d945. Executor source changes are solely environment-access/**;
+remaining changes are generated/state workflow artifacts. Executor commit message
+accurately describes the implementation and bounded validation, with no readiness
+claim. Initial git status was clean.
+
+Coordinator release-external 956d945 records approved artifact preparation over
+the configured HTTPS proxy with TLS verification, authentic local artifact paths,
+and exact versions. This supplies the recorded external confirmation that the
+executor README says was not separately supplied to its session. Independent
+fresh official HTTPS retrieval below confirms present availability through the
+existing configuration. Neither review nor probe changes proxy/system settings,
+selects an alternate route, or disables certificate/engine/integrity checks.
+
+## Commands and observed results
+
+- python3 scripts/tasks.py resume --agent auto-qa-7d3de2e3c758: exit 0, []
+  (reviewer does not claim executor work).
+- python3 scripts/tasks.py show S00-026 and packet S00-026 --agent
+  auto-qa-7d3de2e3c758: exit 0 each; review state, owner, scope and prerequisites
+  confirmed.
+- python3 experiments/0002-xmpp-library/environment-access/verify.py: exit 0.
+  Fresh official HTTPS archive and checksum downloads; SHA256
+  fd8e59d5a511510f6a298afb548f18c7d2b1be404d8b4a27d94fbe49f56cb2d6
+  matched vendor Linux x64 entry before tarfile data-filter extraction.
+  Exact executing Node v24.21.0/npm 11.19.0. Fresh-cache npm ci installed eight
+  packages in 2s with ignore-scripts, strict SSL/engines, HTTPS registry and lock
+  integrity preserved. Actual Stanza createClient ESM import passed.
+- Independent inline Python assertions: exit 0. Both manifest/lock copies equal
+  parent bytes and recorded SHA256; every installed package version equals lock,
+  all eight lock entries use registry HTTPS/SHA512 integrity, actual installed
+  Stanza is 12.22.1. Downloaded archive rehash matches result; persisted checksum
+  material equals fresh download. Pinned npm config get strict-ssl, engine-strict,
+  ignore-scripts each returned true; inherited NODE_TLS_REJECT_UNAUTHORIZED is
+  not 0. Host 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 79.
+- git diff --check: exit 0. Post-probe git diff --stat/status show only the two
+  temporary path values in scoped result.json changed before review metadata.
+
+Review runtime: /tmp/luma-S00-026-r8oxtm9l/node-v24.21.0-linux-x64/bin.
+Review cache: /tmp/luma-S00-026-r8oxtm9l/npm-cache.
+Parent manifest SHA256: e0ffb0c94e198e26f8e44e9b22ff4e121760d9f1197ed7bd5a90e1b4bb112766.
+Parent lock SHA256: 9c85ad62721eb2deacb298f29fa2bae211a29c964707d52c2dfbf8614b7dbb05.
+
+## Acceptance and limits
+
+1. Pass: approved configured access documented by coordinator release and now
+   independently repeated without policy bypass.
+2. Pass: exact pinned Linux tools execute; freshly retrieved vendor checksum
+   matches actual archive.
+3. Pass: unchanged copied parent lock installs with scripts disabled, integrity
+   retained and Stanza 12.22.1 available. No stack/spec/parent lock modification.
+
+Vendor HTTPS checksums establish this bounded authenticity check; no detached
+signature, package provenance/advisory audit or release clearance is claimed.
+No browser/server/client interoperability, WSS, app build or tooling suite was
+run or required for this access probe. Temporary runtime/cache can expire; rerun
+verify.py when needed. result.json now records this independent successful run.
+S00-003, S00-020 and S00-024 remain unfinished; approval may return S00-024 to
+its queue through the CLI, which is not its acceptance. No Git mutations, other
+task selection or agent launch. Coordinator commits this review before further
+fresh work; reviewer exits immediately after approve.
