# mesh-check-toolchain: go
#
# The controller's own check (novox/hq ADR 0237 as amended): the second layer of a pull request's merge
# check, `mesh/repo-check`, run by the build seat in the mesh's Go toolchain — and by hand:
# `MESH_TEST_POSTGRES=… sh merge-check.sh`.
#
# The gate — every machine composed with this change's controller, which judges itself — is the build
# seat's first layer (`mesh/merge-gate`), run because the mesh's module graph builds `mesh-controller`
# from this repository; it is not repeated here. This is the code's own quality and its suite:
#
#   1. formatted and vetted;
#   2. the whole suite, packages in parallel, against the throwaway store the build seat raised at the
#      release the mesh runs; every live test on a bus of its own (internal/testbus), so nothing is
#      serialised. Under the race detector when the toolchain has a C compiler, and said when it has not.
#
# Exit 0 is a pass; anything else fails `mesh/repo-check` with the last line printed.
