Overview

Background worker for running the complete AI analysis pipeline on an image.

== Pipeline (Gemini)

  1. pHash Fingerprint - Perceptual hash for duplicate detection (local)
  2. Gemini Embedding 2 - Native multimodal embedding (image + metadata text)
  3. Gemini Flash Vision - Describes image content (independent, for CRM/metadata)

The embedding step no longer depends on vision analysis — Gemini Embedding 2
natively understands images without a text intermediary.

Examples:

Queue full analysis

ImageFullAnalysisWorker.perform_async(123)

JOB_TRACKING_KEY =

Key used for job tracking.

JOB_TRACKING_TTL =

2.hours.to_i
MODEL =

Model (GA) — sourced from the canonical registry.
