Build a mobile friendly research catalog inspired by Behold A Cooperpedia. Introduce its subject as Bill Cooper, aka Milton William Cooper, aka William Cooper. Provide a chronological catalog, focused research collections, biographies, source links, transcript search and personal notes. Keep each view readable and make lengthy source explanations expandable. Treat a catalog record as a finding aid rather than proof of what a recording says. Record the source title, original date when established, upload date, edition, duration and direct link separately. Preserve competing dates and incomplete records. Do not invent quotations, transcripts, page numbers, timestamps, watched coverage or measured durations. For recordings, identify the specific copy and check important transcript wording against it. Mark automatic transcripts as automatic and unverified. Keep Bill Cooper's statements separate from guests, callers, quoted writers, archival speakers and later commentary. Distinguish autobiography, supporter accounts, public records and independent reporting. An allegation must remain attributed, with relevant replies and qualifications preserved. Do not infer intent, relationships or historical causation from shared topics or repeated claims. For Mystery Babylon, keep the teaching described separate from the speaker's own position and the original source being discussed. Include source notes and citations that lead to an inspected passage or recording location. Keep raw transcripts, corrections and source versions distinct. Make source coverage and unresolved questions visible. Do not imply that the catalog is a trained model or a review of the complete corpus. Keep personal research notes on the device with backup and restore files. Build an offline package for the interface, permitted catalog data and licensed excerpts. External recordings and unbundled documents still need internet access. Do not package private archives or assume public access permits redistribution. Test dates, search, citation links, narrow screens, exports and offline behavior. Deliver a working first version with an evidence checklist. To adapt the framework, change the research subject while preserving chronology, attribution, provenance and honest coverage reporting.
