20-35: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick winCover the filesystem output boundary.
This test checks only the in-memory
outputsmap. It does not compile into a temporary directory or inspect the files that the configured output host creates. Add a filesystem-backed case that asserts hostile version and service-name values cannot create files outside the configured output directory. This is a regression-coverage gap, not evidence of a current production escape.🤖 Prompt for AI Agents

- Line 23: Update the @typespec/compiler dependency in the package manifest to a
version compatible with @typespec/asset-emitter@0.79.3, and align the lockfile
resolution so it no longer uses compiler 1.16.0.

Upgrade the TypeSpec compiler and core libraries to 1.16.0 to fix spec-derived output path traversal (GHSA-2q42-4q24-7rgv), covering eight high-severity Dependabot records. Align companion REST, stream, versioning, and Azure generator-core packages, and patch the newly introduced undici dependency.
Rebase existing compiler, HTTP, and OpenAPI customizations onto the released packages. Preserve visibility-projected model names, discriminated-union object defaults, query serialization, and schema inlining. Keep the existing Python generator patch and its version unchanged; remove patch content already included upstream.
Rebased onto main after #5336 merged; this diff contains the compiler upgrade, compatibility tests, and the asset-emitter compatibility pin.
Validation:
make test-api-spec, Go emitter checks, generated TypeScript SDK type checks, and scoped formatting checks.Summary by CodeRabbit
