# Same hazard, different binary. `telemetry_kill_switch_dispatch` is a
# codewhale-cli integration binary, not `integration`, so none of the filters
# below ever matched it and it ran at full parallelism beside ~15.7k tests.
# Each of its cases spawns the real binary, which gives a detached writer
# thread only CLI_PERSIST_TIMEOUT (250 ms, crates/telemetry/src/lib.rs) to
# re-read config from disk and fsync its batch before the process exits. Under
# Ubuntu CI load that deadline is missed and the dry-run receipt never lands —
# observed at telemetry_kill_switch_dispatch.rs:180 on PR #6104 (2026-09-12)
# and again on PR #6267 (2026-09-16), both Ubuntu-only, both on changes that
# touch neither telemetry nor the CLI.
