[bug] spectra-archive-post-ic/test.sh likely has same grep -qF -- bug (sister from #154)

[kiki830621]

Problem

Source: surfaced during /idd-implement #154 reproduction (Step 5.7)

.claude/scripts/tests/spectra-archive-post-ic/test.sh 可能含同類 bug:grep -qF "$needle" 不加 -- 結尾選項分隔符,當 needle 以 -- 開頭時被 grep 誤判為 flag → silent failure or warning instead of pattern match。

Background

/idd-implement #154 期間我從 spectra-archive-post-ic/test.sh 抄了 fixture-dir test runner 模式做 idd-edit/test.sh。 抄完跑第一次,fixtures 03/04/05 全 FAIL 並印出:

grep: unrecognized option `--scope requires value'
usage: grep [-abcdDEFGHhIiJLlMmnOopqRSsUVvwXxZz] [-A num] [-B num] [-C[num]]
...

修法:grep -qF "$needle" → grep -qF -- "$needle"。 -- 告訴 grep「options 結束,後面是 pattern」。

問題:抄自 spectra-archive-post-ic/test.sh,所以 該 test runner 也可能有同 bug。 若 spectra archive fixtures 的 expected_stdout / expected_stderr needles 沒 -- 開頭,bug 不會 trigger → silent 不知道存在。

Reproduction (untested,需 verify)

1. cd .claude/scripts/tests/spectra-archive-post-ic
2. 加 fixture with expected_stdout.txt containing --some-flag-error-string
3. 跑 bash test.sh
4. 預期:該 fixture FAIL with grep: unrecognized option warning

Impact

• 不會立即壞:現有 spectra-archive-post-ic fixtures 可能都沒 -- prefixed needles,所以 bug 未 trigger
• 未來 risk:加新 fixture 含 --flag 預期值會 silent 失敗(看 PASS 但實際 grep 沒匹配)
• Same-skill instance:#154 是 instance idd-all: 增加 HITL（attended）模式 — direct-commit + 允許 sub-skill AskUserQuestion #1,本 issue verify 後可能升 instance idd-all: direct-commit mode 加 passive warning (dirty tree / on default branch) #2 → 整合進 [infra] IDD plugin test framework — adversarial fixtures for SKILL.md regression coverage (sister concern from #154) #156 framework 設計時 batch fix

Type

bug / test infrastructure

Strategy

1. Verify reproduction(寫 1-2 個 -- prefixed expected fixture 跑看看)
2. 若 trigger → 套同 fix:grep -qF "$needle" → grep -qF -- "$needle" in spectra-archive-post-ic/test.sh
3. 若同時 [infra] IDD plugin test framework — adversarial fixtures for SKILL.md regression coverage (sister concern from #154) #156 trigger generalize → 抽 shared assertion lib .claude/scripts/lib/assert-helpers.sh

Priority

P3 — silent until new -- prefixed fixture added。 file 是為了 audit + 未來 #156 generalize 時 batch fix。
