+### Task B4 Report: Pass `patches` through the build entry points
+
+**Status:** Complete. Commit `bda1a37` — `feat(patches): pass patch registry to bincraft build calls`.
+
+---
+
+#### Edit 1 — `local/build-one.R` (line 106, after `archive = TRUE,`)
+
+```r
+    archive = TRUE,
++   patches = "local/patches",
+    store_build_metadata = TRUE,
+```
+
+#### Edit 2 — `local/build-all.R` (line 142, after `archive = TRUE,`)
+
+```r
+      archive = TRUE,
++     patches = "local/patches",
+      upload = TRUE,
+      store_build_metadata = TRUE
+```
+
+---
+
+#### Verification
+
+```
+parse ok
+```
+
+`Rscript -e 'invisible(parse("local/build-one.R")); invisible(parse("local/build-all.R")); cat("parse ok\n")'` exited 0.
+
+`git diff` (pre-commit) showed exactly 2 insertions, 0 deletions — one line per file, no other changes.

+#### Concerns
+
+None. Both edits are minimal, match surrounding indentation and trailing-comma style, and do not touch any other logic.
