The loop uses ... | while read chain; do (without -r) and then parses JSON from $chain. read will treat backslashes as escapes, which can corrupt JSON strings. Use while IFS= read -r chain; do to ensure the JSON line is read verbatim.

The sed replacement injects $ENDPOINTS directly into the replacement string. If any URI ever contains & (sed replacement expands & to the matched text) or the chosen delimiter (|), the generated YAML will be corrupted. Either escape the replacement (ENDPOINTS_ESCAPED=$(printf '%s' "$ENDPOINTS" | sed 's/[&|\\]/\\&/g')) before sed, or avoid sed entirely by generating the YAML with a templating-safe approach (e.g., have jq emit the full JSON array and substitute that).

Huh. I must have prompted Claude incorrectly, if I wasn't able to find this file.
