Import uses ESM; require uses CommonJS. Root modes use fresh sandboxes. Subpath batches share module caches and globals. Select a result to inspect its evidence.

Does tailwind-merge work in Node.js, Bun and Deno?

All applicable planned loading checks completed. The runtimes used the same installed dependency snapshot. Test environment: Linux amd64 / glibc, with install scripts and execution networking disabled. Successful import or require does not prove that package functions, native features or your application work.

Shared preparation

Passed

1 installed packages · 0 optional dependencies omitted · lifecycle scripts disabled

The omitted count covers locked optional dependencies. Optional peers are separate and are not automatically installed.

Static manifest, native and script observations

Static indicators are context; their presence alone does not establish a prerequisite or failure.

Reproduce these inputs

Download the recorded inputs and exact dependency lock. These files do not include the CLI, runtime images or installed packages.

Reproduction inputs Exact package lock

Local replay requires setup. The CLI currently runs from the CompatLab source repository on a qualified Linux amd64/runsc host. Hosted runtime images are not yet distributed for public download; an operator must supply the exact images named in this report. A fresh image build does not substitute for them. CLI setup and replay requirements

Command for a configured host

Run from the built CompatLab repository with both downloads in that directory and the exact runtime images loaded. Rebuilding creates a new snapshot generation.

sudo "$(command -v node)" apps/cli/dist/bin.js reproduce ./591e30e4-8c19-4acc-9f00-27564ec1e006-reproduction.json --rebuild --lockfile ./package-lock.json --json

The original worker last reported its sealed snapshot as available. Verified reuse requires those actual bytes in your local state directory.

Evidence limitations

Only installation and loading were observed; functional correctness and package safety are not established.
Subpath batches share module caches and globals; root modes use separate fresh sandboxes.
Package-visible harness observations can be tampered with. They are not adversarial attestation.
Evidence applies to these exact artifacts, dependency snapshot, runtime images and Linux amd64/glibc policy.
Runtime error codes are captured observations and can also be thrown by package code.
