tools/sieve-playground builds the vendored sieve-rs 0.7.3 (vnd.inbuxa.* names included) to WebAssembly, with a static page around it, for inbuxa Admin's Debug button on a Sieve script: until now that button sent the script to an outside site whose interpreter knows only upstream's extension names, so any script that requires vnd.inbuxa.* failed to compile there. Ported from the playground in the upstream sieve-rs repository's web/ directory (commit 549a2d57f7), which targets sieve-rs 1.x: - run.rs and handler.rs drive 0.7's event loop the way the server's delivery does, carrying on after a runtime error; llm_prompt compiles and answers false, as on a server without a model. - The expression functions are the server's own modules, included by path; tests fail if the list, ApplyString or the few functions copied from misc.rs/unicode.rs stop matching crates/common. - Built for wasm32-wasip1 rather than with wasm-bindgen: sieve-rs and mail-builder read the clock, which panics on wasm32-unknown-unknown. The page's worker answers the six WASI calls, giving the module the playground's current-time setting. shim/gethostname stands in for a crate with no WASI build. Nothing in vendor/ or crates/ changes. - The page carries no upstream names or links; storage keys and the samples are renamed to match. build.sh --admin <dir> stages the result into an inbuxa-admin checkout.
