## Summary
Fusion npm installs now expose a working `agent-browser` command on
Windows, Linux, and macOS. Fusion publishes a top-level shim backed by
the exact pinned native package, preserving the existing Browser
Verification probe contract on every supported desktop OS.
## Validation
- Added a packed consumer-install matrix for `ubuntu-latest`,
`macos-latest`, and `windows-latest`.
- Each platform executes npm's generated shim, verifies `agent-browser
0.26.0`, and asserts the matching native binary is installed.
- Confirmed the packed Fusion manifest, installed dependency, and
command output all retain the exact declared version pin.
- Passed 101 focused CLI workflow/package tests, full workspace lint and
typecheck, strict changeset validation, and a real macOS ARM64
packed-install smoke.
## Post-Deploy Monitoring & Validation
- Search task logs for `agent-browser not found on PATH`, `Missing
native executable`, and Browser Verification availability warnings.
- Healthy signal: npm installs on Windows, Linux, and macOS resolve
`agent-browser --version` without missing-shim or native-payload errors.
- Failure signal: command resolution errors, version-pin mismatches,
missing native payloads, or increased browser-verification fast-bails.
- Validation window: first release cycle after publish; owner: Fusion
maintainers.
- Mitigation: revert the dependency and top-level shim if install
compatibility regresses.
