Chronology Grounding Update (April 2026)

CHRONOLOGY UPDATE · APRIL 20, 2026

Chronology grounding expanded with 3,179 new evidence chunks.

We just completed a chronology grounding bootstrap across seven evidence lanes, then verified the
results in the live Dave RAG corpus.

Total Inserted

3,179 chronology grounding chunks

Live RAG Size

1,336,069 total chunks after ingest

Evidence Lanes

7 source families integrated

Evidence Lanes Added

Source counts from WO19980 chronology grounding output.

Astronomical Anchors

12 anchor chunks tied to dated astronomical reference points.

Claim Convergence

53 convergence chunks linking claims with support paths.

Biblical Claims

53 claim chunks grounding chronology statements to scriptural sources.

Acts Microdates

34 New Testament microdate chunks from Acts timeline structure.

Regnal Intervals

16 interval chunks from reign spans and date transitions.

Core Event Timeline

3,000 event chunks from chronology event lanes.

Soft Anchors

11 supplemental anchors for continuity where hard-dated links are sparse.

Why This Matters

This update improves answer grounding quality for chronology prompts by giving the model more
structured anchor coverage, denser event context, and clearer claim-to-evidence routing.

Next in the Chronology Path

We will keep publishing focused findings from this lane: anchored date chains, event cluster
explainers, and confidence-based timeline views.
