+# PR #5257: feat(B-0824): post-#5241 enrichments — generators-not-data + bandwidth + 0D/1D/2D/ND + NULL-as-monad + tri-boolean + triangle/GPU
+
+## PR description
+
+## Summary
+
+Clean rebase of 6 Aaron 2026-05-26 substrate landings on top of #5241 (merged 363c7c12). Replaces stale #5256 which had base-conflict.
+
+1. **Generators-not-data** — *"we are inserting / passing the generator combinators not the data itself"*
+2. **Bandwidth payoff** — *"deferred execution at massive scale we are passing the function not the data"*
+3. **Base-dimension agnostic** — *"start even with 1d observables or even scalers and project up"*
+4. **NULL-as-monad** — *"null is the monad we wrap escape in"*
+5. **Tri-boolean logic FTW** — *"tri boolean logic FTW"* (TRIPLE CONVERGENCE on NULL across FP / SQL / operational)
+6. **Triangle/GPU** — *"we can tesselate everyting casue or base is a traingle just like GPUs"* + Aaron-confirmed *"that's what we look like to higher dimensional beings exactly"* (Phoenix-rise IS triangle-mesh-rasterization moment)
+
+Sub-target 8 + 10 added (generator-combinator library design; GPU substrate primitives — HOW = compute substrate; complement to Sub-target 7 WHERE = CockroachDB storage).
+
+XL→L effort schema fix included.
