Blocking Call Audit - https://blocking-call-audit.skillsafe.ai/

This app's agent prompt is a derivative work of one agent skill. It paraphrases and adapts its guidance;
it does not reproduce the skill or its reference files verbatim.

   Modifications: the skill's model and patterns (lazy futures, Tokio tasks and JoinSet, channels over
   shared state, select! for racing futures, graceful shutdown with a CancellationToken, semaphores for
   bounded concurrency, error propagation, and its don'ts - never block in async code, never hold a lock
   across an await, never spawn unboundedly, never ignore errors, never forget Send bounds) were restated
   as deterministic browser checks (rustkit.js) and as the audit and fix lanes of this app's prompt. The
   exact before/after edit contract, the re-check of every edit and returned file, the tokio feature check
   and the changes list tied to the page's flags are additions of this app.

The browser-side checks (rustkit.js), the reconciliation (recon.js) and the rest of the page are original
to this app. Rust is a trademark of the Rust Foundation and Tokio is a project of the Tokio contributors;
