# Ghidra-equipped acquisition worker. Self-contained: bundles JDK 21 + a pinned Ghidra
# release so `docker compose up` just works (at the cost of a heavy, slow-to-build image).
#
# Override the Ghidra build without editing this file:
#   docker build --build-arg GHIDRA_URL=https://github.com/.../ghidra_X_PUBLIC_DATE.zip ...
#
# IMPORTANT: the extractor is a Python (.py) headless post-script, which Ghidra runs via its
# bundled **Jython**. Ghidra 11.4+ / 12.x REMOVED Jython - there `.py` headless needs PyGhidra
# (CPython), which this image doesn't initialise, and you'll get:
#     "Ghidra was not started with PyGhidra. Python is not available"
# So pin a Jython-era release (<= 11.3.x). If this URL 404s, copy the exact filename from
# https://github.com/NationalSecurityAgency/ghidra/releases (form: ghidra_<ver>_PUBLIC_<date>.zip).
