codecov.yml

# Codecov configuration.
#
# Without this file codecov applies its defaults, which put the `patch` target at
# `auto` — the diff must be covered at least as well as the base commit's project
# coverage. That is a reasonable default, but it counts every line in the diff,
# including files the test suite is never supposed to execute.
#
# `ignore` below is for exactly that: standalone developer-tooling scripts that
# are invoked by hand (or by a regeneration step), not library code reached from
# any code path a user or a test takes. They are ~90 lines of file I/O whose
# *behaviour* is already gated by tests:
#
#   schema/regenerate.jl        rewrites problemspec.oss.schema.json.
#                               Guarded by schema/drift.jl, which asserts the
#                               checked-in file equals `emit_schema()` today.
#   schema/emit_hash_fixtures.jl  rewrites hash_fixtures/*.hashes.json.
#                               Guarded by schema/hash_drift.jl, which asserts the
#                               checked-in sidecars equal recomputed digests.
#
# So the guarantee each script exists to provide IS tested; only the argv/print
# plumbing is excluded. Testing the scripts themselves would mean either letting a
# test write into the repo or refactoring a 24-line wrapper for injectable output
# paths — coverage theatre, not a better-tested package.
#
# Deliberately NOT done here: lowering the patch target. The remaining diff is
# library code and should be held to the project's own bar.
