Folds 76 commits of substance since 2026-04-24 into the whitepaper without losing any of the novel cross-domain glue the language earns its keep on. Additions - §4.3 extended from four scopes to five, with bend as feedback across heterogeneous compute (host ↔ GPU). New diagram diagrams/five-scopes-feedback.png stacks the boundaries. - §11.8 Bend: cross-tier GPU dispatch. Wire modes (S-exp text, BSHK binary), worker hosting per tier, spawn-process-stdio + flush-port cross-tier IPC, worker health heartbeat with VRAM-ranked pick, 6-row catalog of live forms (cuda-shake-fanout, cuda-secp256k1-mul, cuda-bignum-cgbn, cuda-radix-sort, cuda-blake3-tree, cuda-sim-ops-bin). New diagram diagrams/bend-dispatch.png. - §2.1 C-tier bignum: arbitrary-precision integers (Boehm-GC managed), which unblocked the secp256k1 widths the GPU forms need on the host side. - §12.1 post-cycle audit: recv-exact O(n²)→O(n), asm scheme_read overflow, asm gc_sweep page-fault, C-tier JIT cur_code restore across CALL/RETURN. - §13 GPU Phase 1 moved from future to shipped; Phase 2 trampolining and Phase 3 interaction combinators sharpened. - Source repo link (git.unturf.com/engineering/unturf/lumbda) added to the cover page band and the Citation block. Compressions (no novel glue dropped — audited per fox's constraint) - §8.2-§8.5 EML derivation prose collapsed into a single §8.2 derivation chain code block; §8.6 renumbered to §8.3. - §6.6.3 adaptive-meta-GC narrative compressed; result table kept. - §7.4.1 GC-build S-expression portal tightened to two paragraphs; "language is its own wire format" insight kept. Preserved in full per audit - §7.5 portable RNG state across tiers - §7.5.1 one-side kernel entropy + portable bit-identical continuation - §11.7 sendfile + adaptive preload (27 KB asm-gc within 2% of Caddy) - §6.6.1 collaborative arena + mark verifier - §6.6.5 precise block typing - §8.1 + §8.3 Lumbda hosts its own EML proof checker, ~16× faster than Lean cold Net RST: 1622 → 1655 lines.
