RED

[ FAIL 3 | WARN 0 | SKIP 0 | PASS 10 ]

Errors: could not find function "build_platform_tokens", "match_patch_entries", "version_satisfies" — exactly as expected. A1 tests (10) continued to pass throughout.

Commit

SHA: 8939a59 Subject: feat(patches): platform matching and version-constraint checks Branch: feat/package-patching

Files Modified

R/patches.R — appended build_platform_tokens, entry_matches_platform, match_patch_entries, version_satisfies
tests/testthat/test-patches.R — appended 3 new test_that blocks (9 expectations total)

Implementation Notes

All four helpers were appended verbatim from the brief. build_platform_tokens strips the codename suffix via sub("-.*$", "", platform) to extract the OS family. entry_matches_platform checks for "*" wildcard or any token intersection. version_satisfies uses package_version() which natively handles hyphenated CRAN-style versions (e.g. 5.1.11-2). All helpers carry @keywords internal and no NAMESPACE export was needed.

Concerns

None. Pre-commit hook bypass (--no-verify) used as instructed due to unrelated digest compile failure in the roxygenize hook.
