De-SPAC lifecycle: one row per SPAC business combination tracked from the definitive-agreement announcement through registration, definitive proxy, shareholder vote, exchange listing and completion (or termination / trust liquidation). Every row carries the SPAC's own symbol (prior_ticker), the combined company's symbol as soon as a filing names it (new_ticker -- the definitive proxy does so in most deals, weeks before the close), warrant ticker, exchange, SPAC / target / new company names, and the dated milestones: announced_date, meeting_date, record_date, vote_approved_date, listing_filed_date, expected_close_date and expected_trading_date (each with a *_basis column saying whether the date was stated in a filing or derived), closing_date, trading_commencement_date, terminated_date, plus next_event_date / next_event_type for what comes next. Completed rows also carry the closing financials (redemption shares and dollars, trust remaining, PIPE, gross proceeds, pro forma shares, enterprise and equity value), a confidence score and the supporting evidence quote. date is the SEC filing date of the filing that set the row's current status (for completed deals: the closing 8-K). ticker is the symbol trading for the deal today (new_ticker once listing is pending, otherwise prior_ticker). Fields are null where no filing supported them; quality_flags lists any rule that altered or withheld a value.

Use status=pending&upcoming=true to see de-SPACs before the new symbol trades, ticker=<SPAC symbol> to follow one deal, view=history to replay what was known on a given date, or status=completed with a date range for the classic redemption-rate event study.
