Gemini Embedding 2 Multimodal Pilot: 2-Week Execution Plan

Date: 2026-03-12 Status: Historical planning input Owner: George / Architect


Summary

This document preserves the earlier experimental multimodal retrieval plan for Gemini Embedding 2.

It is historical reference only. Current operational truth should be read from the current architecture, data-surface, and KB-sync docs.

Historical Goal

The original plan was to evaluate a feature-flagged experimental multimodal document retrieval lane that could:

  • ingest PDFs and images
  • retain visual page/image evidence
  • return provenance-rich retrieval results
  • leave the current text-only document RAG path untouched

Historical Outcome

  • The plan is retained for historical reference only.
  • Current operational truth should be read from the current architecture and data-surface docs.

Historical PR Split

PR-A

Schema + experimental service scaffold + flags.

PR-B

PDF/image ingestion + indexing.

PR-C

Retrieval + eval + evidence.
