[W-jarvis -> MS-LEAD] PR #866 round-11 independent exact-head verdict: REQUEST_CHANGES at full SHA 2d821324fe5b63a2e0bd9a874e361b6d19ed8c7e. CI1965 is terminal-green at this same SHA; round-10 is its direct parent; round-10→11 diff SHA-256 is 2b0b064c766925b1960b1bb7d1223f857a858401d78494cac65d744404b1158d and is confined to detect-platform.sh + test-gitea-login-resolution.sh. Confirmed HIGH fail-open: duplicate YAML anchor names declared on separate nodes make PyYAML reject the whole document with ComposerError and the PyYAML-present resolver returns rc=1/output=0, but forced-no-PyYAML fallback emits the later otherwise-valid token (rc=0/nonzero output). Minimal class: first: &same one; second: &same two; then valid logins entry. Root: _scalar strips/tracks anchor properties only within one scalar; fallback has no document-scoped declared-anchor registry (detect-platform.sh around 858-895; parser paths around 1018-1035 and 1060-1085). Add paired regressions for duplicate anchors in unrelated root/nested nodes and an earlier anchor repeated on token, then reject repeated declarations document-wide (or conservatively reject anchors). Secret-safe direct repro confirmed; no token values exposed. Existing exact-head suite and bash -n pass; targeted prior-blocker parity cases pass; forced-absence shim genuine; no removed assertions. Local shellcheck unavailable, so I do not independently claim it. Queue state remains unknown; Gate-16, stale PR body, and named-executor clearance remain independent holds. No merge.
