+# Task A8 Report: End-to-end patch test and version bump
+
+## Summary
+Task A8 completed successfully. All three steps implemented:
+1. Added guarded e2e test to test-patches.R
+2. Bumped version to 4.3.0.9999 in DESCRIPTION
+3. Prepended NEWS entry to NEWS.md
+
+Commit: d1efec8
+
+## Test Run Output
+```
+$ cd /Users/pjs/git/codefloe.com/rpkgs/bincraftr && Rscript -e 'devtools::load_all("."); testthat::test_file("tests/testthat/test-patches.R")'
+
+i Loading bincraft
+SKIP: 'test-patches.R:246:3' ----------------------
+Reason: nzchar(Sys.getenv("BINCRAFT_PATCH_E2E")) is not TRUE
+
+[ FAIL 0 | WARN 0 | SKIP 1 | PASS 38 ]
+```
+
+## Changes Made
+
+### 1. test-patches.R
+Added guarded e2e test at line 246. The test:
+- Skips unless BINCRAFT_PATCH_E2E env var is set (via `skip_if_not(nzchar(Sys.getenv("BINCRAFT_PATCH_E2E")))`)
+- Skips if offline (via `skip_if_offline()`)
+- Creates a patches registry with RcppParallel env override
+- Calls `build_binary_package()` on rts2 with patches
+- Expects result to be TRUE or "skipped"
+
+### 2. DESCRIPTION
+Bumped `Version:` from `4.2.2.9999` to `4.3.0.9999`
+
+### 3. NEWS.md
+Prepended new section:
+```markdown
+# bincraft 4.3.0
+
+* `build_binary_package()` gains a `patches` argument: a registry of
+  per-package env / configure / Makevars overrides and source diffs that are
+  pre-built into patched binaries and served to pak, fixing compiler- and
+  OS-specific failures (e.g. RcppParallel) including for transitive deps.
+```

+[feat/package-patching d1efec8] test(patches): guarded end-to-end test; bump to 4.3.0.9999

+
+## Test Result Summary
+- All 38 prior tests PASS
+- New e2e test SKIPPED (expected — BINCRAFT_PATCH_E2E not set)
+- No failures or warnings
+- Test will run (not skip) when container executes with `BINCRAFT_PATCH_E2E=1` set
+
+## Environment Note
+The guarded e2e test correctly skips in the local environment (BINCRAFT_PATCH_E2E not set). The actual test execution is deferred to the Linux build-env Docker container run with `BINCRAFT_PATCH_E2E=1` environment variable, where it will build rts2 with the RcppParallel patch applied.
