S00-024: Verify restored pinned Linux XMPP environment access

Changes: Add the S00-024 continuation checkpoint, refresh verified runtime/cache paths, and replace the blocked handoff with QA and S00-020 restart instructions.
Validation: Existing verify.py passed official HTTPS/checksum retrieval, Node 24.21.0/npm 11.19.0, fresh-cache locked npm ci and Stanza import. Independent archive/input/version/config assertions, tasks.py validate and diff/scope/whitespace checks passed. Browser/WSS and product readiness remain unverified.

+Previous interruption/access blocker is no longer reproduced. S00-026 supplied
+reviewed environment-access artifacts; this fresh executor repeated verify.py
+successfully with official HTTPS, vendor archive SHA256, exact Linux Node
+24.21.0/npm 11.19.0 and fresh-cache npm ci installing eight unchanged parent
+locked packages, scripts disabled and strict TLS/engines retained. Actual Stanza
+12.22.1 import passed. No partial source required repair.
 
-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.

+QA should repeat the probe independently, inspect checksum/input/installed
+version checks and scope, then approve or reject only S00-024. Following reviewed
+done, coordinator starts a fresh S00-020 executor which reads its own card and
+uses/reruns the pinned isolated runtime. S00-020 and S00-003 are not completed by
+this checkpoint. No browser/WSS/server/interoperability, detached signature,
+provenance/advisory or release readiness check was performed. No network/system
+configuration, TLS policy, shared contract, dependency graph or spec changed.
