Updates to the timeline

What was added, verified, and changed, with dates. This project is a glass box: the method and its revisions are part of the record.

   Translations are up for grabs

   The Icelandic backfill stands at 19 of 5,226 years and is open for anyone to pick up — as is any new language. The pipeline is CI-integrated with a six-guard correctness chain, so a contributor supplies language review, not infrastructure. Methodology, status and how to claim a locale: the translation project.

   Corpus validation back at 100%

   A full ICCRA validation sweep found 148 events that had drifted outside the schema's category and certainty enums plus one year file missing its graph_edges key. All were normalized through auditable migration scripts — no hand edits — and the corpus validates 5,226 of 5,226 again. Separately, 8 of the 13 pre-schema era dossiers were migrated to evidence schema v1.0.0 with verbatim content and honest nulls where the original research recorded no metrics; the remaining 5 need re-research, not migration.

   Per-page metadata for every year and era

   All 5,226 year pages and every scholarly era now emit their own title, description and social card, built from that year's own headline events; previously they shared one generic site-wide card.

   Era expansion: 21 new scholarly eras defined

   The era model is being extended beyond the linear chronological sweep with thematic lenses (Scientific Revolution, Age of Revolutions, Decolonisation), crisis eras (the Transatlantic Slave Trade, the Black Death, the World Wars) and regional spheres (West African Golden Age, Tang and Song China, Classic Maya). Note that these overlap each other by design and that research is in progress, not complete.

   Research provenance: angle generation separated from evidence

   Research angles and source-bias audits are now generated by one model and the supporting evidence retrieved and verified independently against the scholarly literature, so no single model both proposes a claim and supplies its own support.

   Classical music & opera merged into the major timeline

   The 29-era classical music and opera dataset is no longer a separate section. Its 233 events now sit inside the main year-by-year timeline, tagged Music & Opera, filterable like any other category. The standalone header menu was removed in favour of this tag. The full per-era scholarly folio, with all sources, lives at the music & opera folio.

   Every scholarly source verified against Crossref and DataCite

   The 161 Layer 2 citations were independently checked against the Crossref and DataCite registries. Every DOI resolves to a real paper; the title and author names shown now come straight from those registries (an earlier pass had placed journal names in the author field). Zero fabricated citations, zero retractions.

   Scholarly evidence layer added via a Scite research swarm

   A 29-agent Scite MCP research swarm gathered 161 peer-reviewed sources across all 29 music eras, retraction-enforced. Each era gained a scholarly-evidence panel with a synthesis, sources carrying a stance (supporting / contested / background), and the real debates historians are still having.

   Classical music & opera timeline

   A 29-era chronicle of Western classical music and opera, from Gregorian plainchant to twenty-first-century opera, generated by a parallel agent swarm. Every entry carries a place and an honest historical-confidence level (confirmed to legendary).

    Icelandic translation pipeline

    A CI-integrated pipeline localises the year-level corpus into Icelandic with strict schema and structural guards, so a new English year automatically produces a schema-valid Icelandic counterpart.

    The Notebook, Stratum and Atlas views

    A wholesale editorial rebuild: the parchment Notebook timeline, the Stratum data view, and the map-anchored Atlas globe, with a two-layer navigation and the methodology folio.

    The 5,226-year corpus

    The founding layer: every year from roughly 3200 BCE to 2025 CE researched by an async daemon under the ICCRA schema, 17,991 events with sources, certainty levels, and declared gaps. This is the timeline the music & opera work now sits inside.
