# The npm tarball ships one self-contained bun-compiled binary under
# bin/opencode. Upstream exposes it as both the `opencode` and `opencode2`
# commands; this package ships it as `opencode2` so it can coexist with the
# v1 `opencode-bin` package. No stripping: the binary is bun-generated and
# stripping renders it unusable.
#
# The real binary goes under /usr/libexec and /usr/bin/opencode2 is a small
# wrapper that points XDG_CONFIG_HOME/XDG_DATA_HOME at opencode2-specific
# directories, keeping its config and state out of the v1 opencode folders.
