sec-insider-trades-scraper reads SEC EDGAR's raw ownership XML directly, and a 210-filing measurement found the Rule 10b5-1 plan checkbox serialized four different ways in that XML — 0, 1, true, false — with the natural === 'true' check wrong on 92% of real filings. That is the kind of bug that hides in plain sight: nothing throws, the field is always present, and the column looks fully populated either way.
The obvious next question is whether any of our other government-data Actors — eu-ted-tenders-scraper, trademark-search-scraper, court-records-scraper — could have the same trap sitting unnoticed in a boolean field somewhere. The honest way to answer that is not to re-read three Actors' worth of field-mapping code looking for a bug that might not be there. It's to check whether the precondition for the bug is even present.
The trap needs raw XML. Only one Actor touches it.
The 10b5-1 flag bug exists because SEC's ownership filings are raw XML, hand-parsed, with no schema validation forcing a canonical boolean spelling. A JSON REST API doesn't have this failure mode — true and false are JSON's own boolean literals, and a parser either returns a real bool or the field simply isn't valid JSON. So the question "does this Actor share the trap" collapses to "does this Actor parse raw XML."
A fleet-wide grep across all 23 live Actors' source settles it:
$ grep -rl "xmlMode\s*:\s*true" */src/main.js
sec-insider-trades-scraper/src/main.js
One hit. Every other Actor that touches cheerio (apple-podcasts-scraper, ats-jobs-scraper, shopify-products-scraper, substack-scraper, google-news-scraper) loads it in default HTML mode, scraping rendered pages, not parsing a raw XML schema. The three Actors the follow-up specifically asked about are all JSON REST APIs under the hood — eu-ted-tenders-scraper and trademark-search-scraper call TED's and TMview's own JSON search endpoints, court-records-scraper calls CourtListener's JSON API — fetched with gotScraping and read as parsed JSON, never as a document with tags to walk.
sec-insider-trades-scraper is the only Actor in the fleet that hand-rolls XML tag extraction (cheerio.load(xml, { xmlMode: true })), which is also the only reason it needed a dedicated bool() helper that accepts both spellings in the first place. The other 22 Actors were never exposed to the failure mode — not because nobody checked, but because a JSON parser can't silently misread a true as a 1 that was never there.
Why this is worth stating instead of assuming
It would have been easy to write "checked, no other Actor has this bug" and move on. But that framing invites the same trap the 10b5-1 measurement itself corrected: a claim that sounds verified but was actually reasoned from the Actor's domain (government data) rather than its data format (XML vs. JSON). SEC, EU procurement, EU trademarks and US court records are all "government sources," and it would be a fair guess that they share plumbing. They don't — the format each upstream happens to expose is what determines whether this specific bug class can exist, and that's a one-line grep away from a real answer instead of a guess.
Reproducing
grep -rl "xmlMode\s*:\s*true" */src/main.js # only sec-insider-trades-scraper
grep -rl "cheerio" */src/main.js | xargs grep -L "xmlMode" # everyone else, HTML mode
sec-insider-trades-scraper normalizes all four aff10b5One spellings so rule10b5_1Plan is correct regardless of which filing agent wrote the XML. No API key, no start fee, pay only per transaction row.
