Distrust Green Gate: this PR adds or modifies test file(s) where ALL
tests skip (e.g. pytest.importorskip on a module not yet available), so
CI reports GREEN while asserting nothing. See the check-all-skip job log
for the file and the guard that caused it.

Either implement the guarded code, or waive deliberately with a
Tests-Skipped-Intentionally: <file>, <why> trailer in the PR body.

CRITICAL: Fallback branch calls API and exits 0 while process is still alive

This branch is reached when process_exited=0 (process still alive after timeout), and it calls prepare-shutdown and exits 0. This is the exact bug the PR claims to fix. The comment on line 158 explicitly states "The script must NOT report success (exit 0) when the process is still alive", but this code does precisely that.

WARNING: Unreachable exit 1 — both preceding branches unconditionally exit 0

process_exited is initialized to 0 and only ever set to 1, so one of the two if blocks above always executes and exits. This exit 1 can never be reached.

WARNING: assert all(expected_conditions) always passes

expected_conditions is a list of non-empty strings; all() on a list of truthy values always returns True, so this assertion validates nothing regardless of whether the conditions are actually met.

SUGGESTION: pgrep -f "taos" could match non-controller processes

The pattern matches any process whose full command line contains "taos", such as tail -f taos.log or a test helper script. Combined with the python comm check this is unlikely to select the wrong PID in practice, but a more specific pattern (e.g., the actual server entrypoint) would be more robust.

BOUNCED by the lead (audit 09-10 ~14:5xZ), attempt 3/3 — card goes to needs-human.

1. No red evidence anywhere. Card tsk-fl2kkq demands RED-FIRST. The PR body has no fenced block, and — checked, because a rescue commit can hide a lane's real proof — neither does the commit range: b574167d7 is a single commit whose entire message is the card title. There is nothing showing taos-graceful-stop.sh reporting ready while the process is alive before the fix.

2. The branch ships a scratch script at the repo root. test_fix.py (+56) is an ad-hoc subprocess/os.access script, not a test — it is not under tests/, pytest will collect it by name, and it asserts nothing about the defect. It must not be in the diff at all; the real coverage belongs in tests/scripts/test_graceful_stop_red.py, which this PR also adds.

To land: put the failing run of tests/scripts/test_graceful_stop_red.py against the merge ref, before the scripts/taos-graceful-stop.sh change, inside triple backticks in the PR body, and delete test_fix.py.
