19* Loads a detector from a provider-served obfuscated ESM string (the

20* per-session pool bundle). The module is self-contained, so a dynamic

21* `import()` yields its default export.

22*

23* A blob URL is tried first, then a `data:` URL. The two are gated by

24* different CSP directives and sites commonly allow one without the other — a

25* `script-src` of `*` matches neither, and a policy listing `data:` for

26* scripts and `blob:` only for workers blocks the blob path outright. Without

27* the fallback every session on such a site loses the detector, sends an empty

28* token, and can never pass frictionlessly.

29*

30* A blocked attempt logs a CSP violation before the import rejects. That noise

31* is the cost of recovering the session.

Copied Package Dependency Bridge

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.

Semantic Analysis Limited

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.
