S00-018: Approve bounded XML ingress after independent framing checks

Changes: Accept the isolated S00-018 ingress experiment and bounded ADR; record independent security findings and review handoff. Preserve all browser, live WSS, interoperability and production resource limitations.
Validation: Fresh-cache npm ci and all 55 integrated tests passed on Node 24.21.0/npm 11.19.0; six additional adversarial documents rejected before real JXT.parse with stale callback/fresh attempt checks. Verified ten dependency licenses/integrities, 340 unchanged Stanza files, upstream saxes license bytes and matching digests. Stock defects reproduced; make check passed 72 tooling tests. Initial getter-only tracing attempt failed and is recorded separately. Scope/whitespace inspected; no browser or live WSS test.

+## Independent acceptance

+Security reviewer auto-security-64dc2d9fa232 independently repeated fresh-cache
+npm ci and all 55 integrated tests on Node 24.21.0/npm 11.19.0. Ten exact
+installed dependency licenses/integrities and all 340 unchanged Stanza files
+were checked; the preserved saxes license byte-matches the versioned upstream
+HTTPS source. Additional six adversarial inputs rejected before traced real
+JXT.parse, all four stale socket callbacks left fresh attempts unaffected, and
+fresh attempts imported the exact aggregate-boundary body. make check passed
+72 tooling tests. Public shipped constructor/Transport APIs and enforcement
+order were inspected. The bounded experiment is accepted; every browser,
+WSS/interoperability, aggregate resource, sequencing and production-policy
+limitation above remains. Report records commands and the failed initial tracing
+attempt. Coordinator owns the review commit and subsequent fresh assignment.
