In `@scripts/test-production.sh`:
- Around line 308-320: The join of multiple CNAME targets uses "$(printf '%s'
"$targets" | paste -sd ', ' -)" which incorrectly treats ', ' as alternating
single-character delimiters; update the message construction so targets are
joined with the literal string ", " instead of alternating delimiters — locate
the expression used inside the message variable (around the variables targets
and message and before the EXPECTED_CNAME_STRICT check) and replace it with a
join that produces "a, b, c" (for example: join with paste -sd',' - then insert
spaces, or use awk/printf to append ", " between entries and trim the trailing
separator) so the fail/warn output shows properly spaced comma-separated
targets.
- Around line 275-283: The assertion in check_network_config() that compares
"data.rpcUrls && data.rpcUrls[0]" to "${BASE_URL}/rpc" fails for secondary/proxy
URLs; change it to use an override ENV var (EXPECTED_RPC_URL) when present:
compute expected_rpc_url="${EXPECTED_RPC_URL:-${BASE_URL}/rpc}" and use that in
the assert_json_field_equals call for "network first rpcUrl"; keep BASE_URL
logic and other checks unchanged so callers can set EXPECTED_RPC_URL when
validating standby/Cloudflare-tunnel URLs.
- Around line 286-290: The normalize_dns_name function uses bash-only lowercase
expansion `${name,,}` which fails on macOS bash 3.2; update normalize_dns_name
to perform lowercase conversion using a POSIX-safe tr pipeline instead (preserve
the existing removal of a trailing dot via `${name%.}` then pipe the resulting
value through tr '[:upper:]' '[:lower:]'), and ensure the function still prints
the normalized name with printf '%s\n' so callers like those using
EXPECTED_CNAME_TARGET behave identically.

🧩 Analysis chain
🌐 Web query:
Does bash 3.2 on macOS support ${var,,} lowercase parameter expansion?
💡 Result:
No. Bash 3.2 on macOS does not support the lowercase parameter expansion syntax ${var,,}. In bash, the case-modification parameter expansion forms ${parameter,pattern} and ${parameter,,pattern} (including ${parameter,,} to lowercase all matched characters) are defined in the “Shell Parameter Expansion” section of the Bash Reference Manual [1]. Those case-modification operators were introduced with Bash 4.0+; accordingly, they are not available in older Bash versions such as 3.2.x shipped on macOS [2][3]. What you’ll see in practice on Bash 3.2 is an error like “bad substitution” when trying ${var,,}, while Bash 4.0+ accepts it [4]. For macOS default Bash 3.2, use a different approach such as tr (e.g., echo "$VAR" | tr '[:upper:]' '[:lower:]') as suggested for Bash 3 [5].

${name,,} ไม่รองรับใน bash 3.2 ที่มาพร้อม macOS ค่าเริ่มต้น
English: The ${var,,} parameter expansion for lowercase conversion requires bash 4.0+. Since macOS ships with /bin/bash 3.2.57 by default, invoking normalize_dns_name when EXPECTED_CNAME_TARGET is set will abort with bad substitution. Lines 300 and 302 in the same file already use the POSIX-portable tr '[:upper:]' '[:lower:]' idiom for the same operation.
ภาษาไทย: ${name,,} ต้องการ bash 4.0 ขึ้นไป ขณะที่ macOS ใช้ /bin/bash 3.2.57 เป็นค่าเริ่มต้น ทำให้เมื่อ EXPECTED_CNAME_TARGET ถูกตั้งค่าและเรียก normalize_dns_name จะล้มเหลวด้วย bad substitution ควรใช้ tr '[:upper:]' '[:lower:]' เหมือนที่ใช้ในบรรทัด 300 และ 302 แทน

paste -sd', ' วนซ้ำ delimiter แยกกัน , และ — ผลลัพธ์ผิดเมื่อมีหลาย CNAME targets
English: paste -d treats its argument as a list of individual delimiter characters that cycle in turn. So -d', ' means , is delimiter #1 and (space) is delimiter #2. For two targets the output is a,b (no space), and for three targets the paste command will cycle: , then alternating, producing a,b c instead of the intended a, b, c. While a single CNAME target is the overwhelming norm, the formatter should still be correct.
ภาษาไทย: paste -d', ' ใช้ , และ เป็น delimiter สองตัวสลับกัน ไม่ใช่สตริง ", " ทั้งก้อน สำหรับ 2 targets จะได้ a,b (ไม่มีช่องว่าง) สำหรับ 3 targets จะได้ a,b c แทนที่จะเป็น a, b, c

- Around line 114-120: The startMockServer function has a type mismatch: the
default parameter handlerOverrides is set to an empty object {} on line 114, but
line 119 treats it as a function by calling handlerOverrides(base). When
startMockServer is called without arguments, this causes a TypeError. Change the
default parameter from an empty object to a function that returns an empty
object, so the default should be handlerOverrides = () => ({}) instead of
handlerOverrides = {}, ensuring it can be safely called as a function regardless
of whether an argument is provided.
