# Hash Bags: every CI workflow (android/ios-sim/ios-testflight/linux/windows)
# consumes PREBUILT .so/.a files from monero_c's release-bundle.zip. None of
# them compile monero_c from source. The only thing they need out of this
# checkout is `git describe --tags`, which resolves the release/<tag>/ path.
#
# So by default we do NOT init the monero/wownero submodules. Besides saving
# ~1GB of source plus deep transitive submodules per CI run, this decouples us
# from where Wownero is hosted:
#
#   Wownero left Codeberg in July 2026 (Codeberg announced it would ban crypto
#   projects) and remigrated to https://github.com/wownero/wownero. monero_c's
#   .gitmodules still points at the dead Codeberg URLs, which now fail with
#   "remote: Bye" / HTTP 403. That is what broke the iOS TestFlight build on
#   2026-07-31 — at a step that never needed the source in the first place.
#
# Set MONERO_C_BUILD_FROM_SOURCE=1 only if you genuinely intend to compile
# monero_c yourself. See the caveat below before you do.

    # Redirect the dead Codeberg URLs to where the code actually lives now.
    # Safe despite being a host swap: both submodules are pinned to exact
    # commit SHAs, and git verifies the object hash on fetch, so a different
    # host cannot substitute different content under the same SHA.

    #                remigration off Codeberg)
    #   randomwow -> github.com/mrcyjanek/randomwow, which is what monero_c
    #                itself switches the remote to in apply_patches.sh. Note
    #                this is NOT github.com/wownero/RandomWOW — that one is a
    #                fork of tevador/RandomX on a different lineage and does
    #                not contain the pinned commit. The redirect has to happen
    #                here because apply_patches.sh only runs AFTER the clone
    #                that would otherwise fail against Codeberg.
