Nothing gets quietly fixed here. If we found it, got it wrong publicly, and fixed it, it's on this page with the date and the real impact — same standard as the Ledger not deleting losing calls.
What happened: SEC's daily filing index lists a single Form 4 once for every CIK it touches — the issuer and every reporting owner each get their own line in the index, all pointing at the identical underlying filing. Our scanner was treating every index line as a separate filing. A straightforward purchase (one issuer, one owner) got counted twice. Filings with several related reporting-owner entities — a fund structure, for example — got counted as many as 11 times for one real transaction.
What it affected: dollar totals and "N insiders" counts in posts built from the automated daily-scan path, before the fix landed on 2026-10-13. A real example: a post on $REF read "6 insiders ... bought a combined $6.1M." The real number, after the fix, is 3 insiders, $3.06M — exactly half, which is the expected signature of this bug on a simple one-issuer, one-owner filing.
What was NOT affected: the Ledger database itself. A schema constraint already in place happened to collapse the duplicate rows automatically, so every number shown on the Ledger — including throughout the period this bug existed — was already correct. You can verify this yourself: ticker pages that were affected show the real, corrected transaction count and dollar total in their "Insider activity" table, which you can compare against the (inflated) tweet text still shown in their "Our calls" table on the same page.
What we can't fix: posts already live on X can't be edited. Any post built from the automated path before 2026-10-13 may overstate its dollar total and insider count, typically by roughly 2x. We're not deleting or hiding those posts — they stay up, same as a losing call stays on the Ledger — but the real numbers are always the ones on the Ledger page for that ticker, not the ones in the original post text.
The fix: the scanner now deduplicates by SEC accession number — the real, unique identity of a filing — before ever fetching or counting it, regardless of how many CIK paths the daily index lists it under.
