fix: Telegram listener — async command execution + singleton guard
Root cause: run_and_reply() blocked the entire listener synchronously.
FFmpeg hung because child processes inherited stdin (waiting for 'q').
Long-running commands froze the listener for up to 120s.

Fix:
- Commands run in background with stdin=/dev/null, output to temp file
- reap_commands() collects output non-blocking after each getUpdates cycle
- SIGCHLD handler pre-caches exit codes via wait -n
- TERM/INT trap kills background processes and cleans temp files
- Singleton guard (flock) prevents duplicate listeners racing getUpdates

Tests:
- t-telegram-listener-exec.sh: 12 hermetic checks (echo, pipes, stderr,
  compound commands, long-running, quiet mode)
- t-telegram-listener-singleton.sh: 8 checks (lock acquire/release/status)

Architect verdict: accepted as-is, no re-architecture needed.

tests/ — regression test suite

Zero-dependency Bash regression tests for the Linux_post_install repository.

Run

make test          # discover tests/t-*.sh, run everything
./tests/run-tests.sh                     # same
./tests/run-tests.sh t-telegram-auth.sh  # run one file

Exit code is non-zero if any check failed. The suite is designed to be deterministic: tests stub every external dependency they touch (curl, gpg, sudo, systemctl, llama-server, nvidia-smi…) and run against sandbox temp dirs. No network, no sudo, no system changes.

Adding a test

  1. Create tests/t-<what>.sh with a run_test() function. set -euo pipefail is already active (the runner re-asserts it); $ROOT is the repo root, $TEST_TMP a per-test temp dir that is cleaned automatically.
  2. Use the helpers in tests/test-lib.sh for every assertion: check, check_eq, check_rc, check_contains, check_not_contains, check_file_exists, check_file_absent, test_run / test_run_env, mksandbox, tracked_tree_copy, count_token.
  3. If a case cannot run in the current environment (missing binary, missing analyzer), call skip_case "<desc>" "<reason>" — never fake a pass and never silently return.
  4. Keep total suite runtime under 90 seconds.

Skip contract (hard)

A test that cannot run must say [SKIP] reason. The runner counts skips in the summary and a file whose run_test() produced zero checks and zero skips is reported as FAIL ("no assertions") — a broken harness can never pass silently.

t-ai-hf-download.sh pos ai hf download success + failure honesty (no .hf-meta on partial failure, rc != 0)
t-ai-key-resolution.sh pos ai API-key contract: provider key > legacy AI_API_KEY fallback > error; leakage guard, env-wins, providers status sync
t-ai-llama-detect.sh pos ai-server status version detection, "unknown", missing-binary failure

t-share-mountpoint.sh share-client ask_mountpoint UX: existing/new/declined/rejected paths, confirm gate, mkdir side effects, non-TTY stdin contract, static nt guards
t-pos-media-yt.sh unified pos media yt suite: dispatcher + forwarder resolution, shared yt-lib helpers, yt-mp3/mp4/grab/subtitles flags, dry-run deps, YT_OUT_DIR seam, GRAB_DEFAULT config, negative controls (unsafe-URL no-expansion, --lang en,ar single arg, txt timestamp-stripping)
t-telegram-listener-singleton.sh Telegram listener single-instance guard: first --run acquires the flock, second --run fails fast with the exact message, lock auto-releases so the next start is clean, --status reports the lock state
