+Aaron explicit authorization: *"yes we should backlog"* — operator-authorized landing of [B-0668](../../../../../../docs/backlog/P1/B-0668-compositional-dbsp-frame-architecture-gnostic-2d-base-plus-two-wolves-emotion-meta-plus-clifford-rx-bonsai-meta-tagged-dims-plus-fsharp-ce-composition-operator-aaron-2026-05-19.md) via [#4281](https://github.com/Lucent-Financial-Group/Zeta/pull/4281).
+
+ID allocation: B-0667 highest on main; B-0700/0701/0702 in flight from separate batch; B-0668 confirmed free via PR-title scan. Filed P1.
+
+Architecture preserved:
+
+- **BASE**: gnostic 2D (remember-when × pay-attention) — bandwidth-engineering encoding
+- **META frame 1**: chaos-theory two-wolves emotion 2D (composes with B-0667 4 attractors + DeepSeek substrate #4198)
+- **META frame N**: Clifford-space meta-tagged dims → Rx bonsai serialized queries (B-0640)
+- **COMPOSITION OPERATOR**: F# computation expression (monadic let-bang as native dimension-addition mechanism)
+- **RECURSIVE**: each meta-frame is itself a F# CE composing with base; type system enforces correctness
+
+All 4 framings passed razor-discipline per god-tier-claims rule. Composes with B-0644/B-0665/B-0666/B-0667 keystones + B-0640 Rx bonsai + B-0635 wave-particle tick-source + B-0637 Infer.NET BP/EP.
