+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.
