# COPILOT_HMAC_KEY (CI sets one as a job-level credential) would be picked over
# the token the replay snapshots expect, yielding 401s. For the in-process
# transport the runtime is hosted in this test process and can capture the key as
# early as client construction, so neutralize it at module load — the analogue of
# .NET's InProcessEnvIsolation [ModuleInitializer] and Node's module-init guard.
# Out-of-process children resolve auth in their own process where the token already
# outranks HMAC. See https://github.com/github/copilot-sdk/issues/1934.
