SEC 8-K material-event velocity (monthly)

Monthly enrichment panel scoring how actively ~58 SEC-registered US and Canadian companies disclose material events. Each run fetches the keyless SEC EDGAR submissions JSON per company (ticker->CIK resolved from the SEC's own company_tickers_exchange.json) and classifies every 8-K's item codes into a documented 8-category taxonomy over the trailing 12 complete months. Per (company, month): 8-K counts by category, has_earnings_8k (item 2.02) and has_exec_change_8k (item 5.02) flags, event_intensity_score = 100 * (0.60 * min-max(n_8k) + 0.40 * min-max(n_governance + n_financial)) normalized within each month, a deterministic intensity_rank, and spike_flag when n_8k >= 2 with z >= 2.0 against the company's own 12-month baseline; every row carries its CIK and the exact source_url it was built from, the panel is dense and zero-filled, and foreign private issuers (6-K/40-F, no 8-K) keep structural zeros flagged by is_8k_filer. Who joins this: a quant desk joins monthly per-ticker event intensity to returns on ticker + month for event studies, and an IR/comms team benchmarks disclosure cadence against peers on company_name (primary key (as_of, month, company_name); join keys ticker, company_name, month, country_code ISO alpha-3). Caveats: category counts are item-code occurrences (a \"2.02,9.01\" filing counts once as financial and once as exhibits); intensity scores are within-month relative and not comparable across months; private companies and tickers absent from the SEC file are excluded.
