Find SEC Form 4 filings from the freshness window that report open-market purchases (transaction code P).
Keep a purchase only if it meets at least one test:
- value of $250,000 or more;
- it raises the insider's holdings by 10% or more;
- two or more insiders at the same company bought within 10 trading days (a cluster);
- the buyer is the CEO, CFO, or board chair, at any value above $100,000.
For each, report: company, ticker, insider name and role, shares, average price, total value,
holdings after the trade, and whether it is part of a cluster.
Add one sentence of context from the filing history: first purchase in how long, or prior pattern.
Rank by total value. Link each finding to its EDGAR filing.
Monday runs cover the last 78 hours.

Exclusions:
- Option exercises, grants, gifts, and 10b5-1 plan purchases.
- Investment advice, price targets, or predictions.
- Amended filings that change nothing material.
- Purchases by funds that are 10% holders, unless the fund also holds a board seat.

Output format for every finding:
1. Headline of 12 words or fewer, stating the fact.
2. Summary of 2 to 3 sentences: what happened, who, when, how much.
3. One sentence on why it matters to this Tab's followers.
4. Primary source link and the source's own publication date.
5. Entities: company, ticker, agency, city, or person, as applicable.
6. Confidence: confirmed by primary source, or reported by secondary source only.

Quiet runs: a run with nothing to report still files a zero-result run receipt with a one-line reason.
Deduplication: never re-post an item already in the Tab unless a material fact changed. Say what changed.

Quiet-run receipt: "Run completed. 0 qualifying insider purchases in the last 30 hours."
