Seven call sites hand-split trace bodies with the same lines.find +
split("=") pattern; extract utils/parse-trace.js and route them all
through it. The parser trims keys and values, so bodies re-serialized
with CRLF by middleboxes no longer leak a trailing "\r" into the IP.
SpeedTest's invalid-IP throw now carries a self-describing detail
(no-ip-line / empty-value / length + tail charcode) to tell response
tampering apart from format surprises.

// Shared parser for Cloudflare /cdn-cgi/trace responses (key=value lines).

//
|
|
// Every trace consumer — the getips/ IP sources, SpeedTest, RuleTest — goes
|
|
// through this instead of hand-splitting lines. Values are trimmed because a
|
|
// body that crossed a rewriting middlebox (TLS-decrypting proxy, corporate
|
|
// gateway) can arrive with CRLF line endings, and a trailing "\r" on the ip
|
|
// value would fail IP validation downstream.
|
|
|
|
// Parse a trace body into a { key: value } map. Non-string input yields {}.
|
|
// Each line splits on its first "=" only (values may themselves contain "=");
|
|
// keys and values are trimmed; lines without a key are skipped. Missing keys
|
|
// simply stay absent, so callers read them as undefined.
