Three new tables for the canary tokens feature:
- canary_blobs — operator-uploaded source artifacts, deduped by sha256
- canary_tokens — one planted artifact in one decky; carries the
callback slug, generator/instrumenter, and lifecycle
- canary_triggers — append-only log of every callback hit; attacker_id
back-filled by the correlator
Pydantic request/response shapes live in the same file per the
single-source-of-truth convention. No migrations file — pre-v1
SQLModel.metadata.create_all() covers it.
