Tasks

• Add local dependency-free visual similarity review groups using metadata heuristics.
• Add CLI and MCP similarity review commands.
• Add dashboard similarity review queue and smart collection.
• Add dry-run-first batch curation across CLI, MCP, and dashboard selected-assets handoff.
• Research permissive local embedding options and external adapter options.
• Add embedding table and schema.
• Add CLI dry-run for embedding selected assets.
• Add semantic search UI mode.

Acceptance

• Search can find assets by meaning, not only filename or tag.
• Provider and model used are recorded for provenance and reproducibility.

Agent Notes

• Keep writes, uploads, publishing, wallet actions, paid services, and file deletion human-gated.
• Keep Music IS canonical for music release state; VIS indexes and links assets.
• Keep Eagle, Drive, Cloudinary, R2, Postiz, and Web3 services as adapters unless a later issue explicitly changes that boundary.
