1% ============================================================================2\section{Limitations, Reproducibility and Conclusion}\label{sec:conclusion}3% ============================================================================45\subsection{Limitations}67Beyond the identification limits above, the current build has concrete technical limitations that bound its use. The issuer universe is a fund-holdings proxy at one date, not licensed Russell membership, and 65 of its issuers are outside the form scope. The parser stores section-level provenance but not character offsets into the raw HTML. The focus windows truncate long sections around lexical cues, so recall on annual reports is unknown and probably lower than on 8-Ks. The resolver is a deterministic key that both merges distinct phases and splits renamed initiatives, and the resulting project count is therefore an artifact of the key as much as a count of initiatives. Amounts carry no type and no realization flag. The 10-Q financial-statement and 8-K sections are read whole, while 10-K Items 3--6 and 8--9B are not read at all. And the ledger cannot yet distinguish an empty result from a failed call.89\subsection{Reproducibility, ethics and terms}1011The corpus layer and the project layer are reproducible from the Git repository at revision \texttt{2324b58}, the frozen universe artifact, the download logs and the extraction ledger; the paid extraction step is resumable and idempotent, and the complete run costs roughly 775~USD at October 2026 prices. All numbers in this paper are regenerated by \texttt{code/export\_stats.py} and \texttt{code/make\_tables.py}. The raw filings are public documents retrieved under the SEC's fair-access policy with an identified research client; they are not redistributed, and the repository contains no credentials and no private infrastructure details. Derived datasets (project-level, mention-level, issuer-year and event-time exports) will be released with sample restrictions and a data dictionary once gates (c), (d) and (g) are met. The database does not contain personal data; the only names it stores are those of corporations, places and technologies as they appear in public filings.1213\subsection{Conclusion}1415We have documented a reproducible pipeline that turns 527{,}548 SEC filings of 2{,}564 issuers into 308{,}065 evidence-linked statements about 121{,}099 disclosed strategic initiatives, each traceable to an accession number and a filing section, classified into a 21-category taxonomy and organized into timelines. We have been equally explicit about what has \emph{not} been done: the accuracy of extraction, classification and linkage has not been measured against independent human labels; amounts are not typed; events are not separated; the universe is a snapshot. The contribution of this paper is therefore the instrument and its audit rather than a validated measurement. The next step of the research program is the annotation study and the linkage audit described in Section~\ref{sec:validation}; only their results will determine whether the counts reported here can be used as variables, and with what measurement-error model. Until then, SPID is a research database under validation, and we ask that it be cited and used as such.16
