The quickjs-reactive-probe was extended to load @alkdev/operations (registry,
call protocol, response envelopes, ACL, buildCallHandler) alongside the
reactive core. All five operations assertions pass on QuickJS-NG via rquickjs:
registry/execute/envelope/acl/callHandler. 271 modules loaded total.
This closes the third highest-leverage unknown: the operations protocol is
runtime-agnostic in practice, not just in theory. Adds a new section on the
QuickJS UDF host convergence — a minimal isolate speaking the same bidirectional
operations protocol as the TypeScript reference, the Rust alknet-call port,
and the planned NAPI/Python adapters, without needing Node/Deno/Bun. Connects
to the toolEnv WASM-QuickJS sandbox precedent at /workspace/toolEnv.
Captures the two completed POCs that resolve the highest-leverage unknowns
around the alknet-desktop direction (Rust + wgpu + rquickjs + ujsx over three.js):
- ui-spoke-poc: headless WebGPU rendering in Deno, three.js WebGPURenderer via
device-capture, MSDF text (the '2D UI is rocket surgery' subproblem)
- quickjs-reactive-probe: @preact/signals-core + @alkdev/typebox + @alkdev/ujsx
reconciler verified compatible with QuickJS-NG via rquickjs
Documents the rejected deno-desktop alternative, the established architectural
direction (head-worker over irpc/ALPN, two HostConfigs over one wgpu surface),
headless/headed parity via llvmpipe, the supply-chain surface reduction, and
the open unknowns that remain before SDD can begin.
