Suggested reviewers: Merge Risk: 🔵 Low · up to The change is mergeable with owner awareness that some suffixless tar and ZIP files may still be copied rather than unpacked, or fail during unpacking. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Extensionless downloads can now be unpacked and used during installation. Existing checksum checks limit who can change most of those downloads, but archive extraction adds a containment question that this review could not fully resolve. No archive escape or other security finding was verified. Retained concerns

- Line 2114: Update the tar detection check in `stage_source` to validate the
first header and its checksum when the `ustar` marker is absent, so valid V7
tarballs are recognized and unpacked. Add a V7 case alongside the existing tar
detection tests.

- Around line 110-111: Replace the four-byte ZIP signature check in the archive
unpacking flow with an `unzip -t` probe so valid ZIPs with prepended stubs are
detected; treat status 1 as a valid ZIP warning, status 9 as a non-ZIP and
continue to tar detection and copying, and allow status 1 during extraction.
Update `system_or_die` to support the required allowed status without changing
its default failure behavior.

Formula sources were staged by file name alone. A URL such as GitHub's `https://codeload.github.com/<owner>/<repo>/tar.gz/refs/tags/v0.0.23` has no extension, so `ExtractionFormat::from_file_name` returned `Raw` and the tarball was copied into the build directory unextracted. The formula's `install` then ran against a lone gzip file, e.g. `go build` failing with "go.mod file not found". `brew` handles these by falling back to the file's content when the name is inconclusive. This surfaced building `cf-vault` from the `jacobbednarz/tap` formula, whose `url` is exactly such a codeload URL: https://github.com/jacobbednarz/homebrew-tap/blob/b03141211969573bb4b4fcc9c3016ba04e5898ec/Formula/cf-vault.rb Add `ExtractionFormat::detect`, which keeps the name's verdict when it has one and otherwise sniffs the leading bytes via `ExtractionFormat::from_magic`: zip, or a gzip/xz/bzip2/zstd/plain stream whose payload opens with a ustar header. Requiring the tar header keeps bare compressed files and binaries staged as-is. Formula source staging uses it, and it replaces the cask fetcher's zip-only `detect_extraction_format`, so suffixless tarballs in casks are unpacked too rather than copied as a raw binary. The shim's `MiseDownload.unpack`, which stages formula resources, had the same name-only check; it now falls back to the zip magic or a `tar tf` probe.
The shim stages formula `resource`s itself through `MiseDownload.unpack`, so its zip/`tar tf` fallback for extensionless URLs was only exercised by hand. Run the real shim against a formula whose resources are a suffixless gzip tarball, a plain script and an empty file, and check the keg contents. The download cache is pre-seeded, so `MiseDownload.fetch` never reaches the network. The shim needs Ruby 3 or later (it uses endless methods), so the test reuses `tap.rs`'s `test_ruby()`, now shared as a `#[cfg(test)]` helper, instead of a bare `which ruby` that could find macOS's system Ruby 2.6.
