+# `.github/oss-fuzz/` — staging directory for OSS-Fuzz upstream submission
+
+This directory holds the three files that get copied verbatim to
+`projects/ghidra-decompiler/` in [google/oss-fuzz](https://github.com/google/oss-fuzz):
+
+- [`project.yaml`](project.yaml) — OSS-Fuzz manifest (contacts, sanitizers, engines)
+- [`Dockerfile`](Dockerfile) — build container definition
+- [`build.sh`](build.sh) — harness build script
+
+See [`docs/security/OSS_FUZZ.md`](../../docs/security/OSS_FUZZ.md) for the
+broader integration plan and the in-tree harness sources at
+`Ghidra/Features/Decompiler/src/decompile/cpp/fuzz/`.
+
+## Sync workflow
+
+Files here are kept byte-identical with their upstream counterparts at
+[`google/oss-fuzz/projects/ghidra-decompiler/`](https://github.com/google/oss-fuzz/tree/master/projects/ghidra-decompiler).
+Editing in either location requires copying to the other in the same
+sweep so the two don't drift.
+
+The Google-style `Copyright YYYY Google LLC` Apache 2.0 header on
+`Dockerfile` and `build.sh` is the OSS-Fuzz convention for everything
+under `projects/` — `dpebot`'s `header-check` bot enforces it on every
+PR to google/oss-fuzz. Carrying the same header in-tree keeps the
+`cp`-to-upstream operation a one-step sync rather than a diff-and-fix.
