fix: verify and document GH#4271 quality-debt findings in stats-wrapper.sh#4288
Conversation
…per.sh All 3 PR #4232 review findings are confirmed addressed: - CRITICAL (coderabbit): ps probes guarded with || true so set -euo pipefail cannot abort before etime fallback runs (commit 80ee81f) - HIGH (coderabbit): pidfile preserved for live PIDs via kill -0 check; only removed when process is confirmed gone (commit 80ee81f) - MEDIUM (gemini): awk uses exit 1 for invalid input; || true on command substitution is intentional to prevent set -e abort on parse failure (commit 268ad84) Adds inline comment explaining the || true design rationale so future reviewers understand it is not a suppression but a deliberate guard.

Code Review
This pull request adds comments to document the rationale behind some of the logic in stats-wrapper.sh. While documenting code is a great practice, the added comments are very specific to the review history of the code (mentioning PR numbers and review tools). For better long-term maintainability, I've suggested refactoring the comments to focus on the technical 'why' behind the implementation, rather than the historical 'who' and 'when', which is better tracked by version control history. This aligns with the rule to provide clear, single justifications for design choices in comments.

While adding comments to explain the rationale is excellent, these comments are tied very specifically to the development history (GitHub issues, PRs, and review tools). For better long-term maintainability, it's preferable for code comments to explain the why of the logic itself, rather than the history of how it came to be. The git history is the best place for that context.
I suggest rephrasing these comments to be more evergreen and focused on the technical reasons for the implementation choices.

| # Robustness notes: | |
| # - The `ps` commands use `|| true` to prevent `set -euo pipefail` from | |
| # aborting the script if the process disappears. This allows the `etime` | |
| # fallback logic to execute. | |
| # - The `awk` command substitution also uses `|| true`. `awk` is scripted to | |
| # `exit 1` on invalid input, and this guard prevents script termination. | |
| # The subsequent `^[0-9]+$` check handles the empty output case. |
References
- Ensure comments provide a single, clear justification for a design choice, avoiding the presentation of multiple, potentially conflicting rationales.
…ments in stats-wrapper.sh Replace GH issue/PR references in robustness notes with evergreen comments that explain the technical why (set -euo pipefail guard behaviour, awk exit semantics, empty-output handling) rather than the development history.

Summary
Closes #4271
Verifies all 3 review findings from PR #4232 are fully addressed in
.agents/scripts/stats-wrapper.sh, and adds an inline comment documenting the design rationale so future reviewers understand the|| trueguard is intentional.Findings Status
CRITICAL — Guard
psprobes so fallback can run (coderabbit, line 43/50)Status: ✅ Already fixed (commit

psprobes use|| trueguards soset -euo pipefailcannot abort the function before theetimefallback runs:HIGH — Don't drop pidfile on ambiguous elapsed-time lookup failure (coderabbit, line 118)
Status: ✅ Already fixed (commit
80ee81fin PR #4232)The failure path checks process liveness with
kill -0before removing the pidfile. If the process is still alive, the pidfile is preserved and the function returns 1 (skip):MEDIUM — Use
exit 1in awk for invalid input (gemini, line 74)Status: ✅ Already fixed (commit
268ad841in PR #4232)The awk command uses
exit 1for all invalid-input branches. The|| trueguard on the command substitution is intentional — it preventsset -euo pipefailfrom aborting the function on awk parse failure (this is the critical fix from80ee81f). Removing|| trueas the gemini suggestion proposed would reintroduce the critical bug; the current code correctly incorporates both fixes.Change in This PR
