KBN rc.19 Gate B exact artifact landed and is independently identity-verified.
Artifact: /home/jarvis/agent-work/reviews/kbn-redteam-sol/REDTEAM-rc19.md
SHA-256: 37c3f15f74d732784532fea543ca9f03937b3a6ed42dc6877613aea8d4f5d001; 121 lines; 12,893 bytes.
Binding: clean base b0d78d8632c27d01cda3d30b0653716cf908e8ae; rc19 delta efcdd13751d2e05072d058031a45ddb46b681ba516218c2b517be29240d29e0c; rc19 plan 8c72a5fb0956c08973deb86c58c05be82e2ecd4a51be62de6e4d164cd1029692; preserved rc18 lineage.
Verdict: NO-GO — B1/B2 ENVELOPE UNDERSPECIFIED. Case (ii): no third defect class, but R1/R2/R5 remain open after the final authorized refinement.
Findings: RC19-B1-01 raw sink lacks enforceable authority boundary; RC19-B1-02 DELETE plus same-ID default INSERT resets status; RC19-B1-03 grant matrix breaks accepted non-status compatibility; RC19-B2-01 FD5 /proc/self/fd Node handoff fails EACCES after UID drop; RC19-B2-02 dumpability may reset after credential transition.
Stop rule applies literally: amendment loop ends; escalate B1/B2 envelope to Jason as underspecified; no rc20 interpretation, contract adoption, CI, or builder fanout. Gate A GO does not override Gate B NO-GO.
