Advanced Field Knowledge and Competitiveness

Write verifiable acceptance criteria and edge cases for the system’s note-ingestion, daily-review, feedback, and reminder workflows.

Create a component diagram that assigns clear responsibilities to Obsidian/GitHub synchronization, FastAPI, PostgreSQL, the scheduling engine, embedding services, and Telegram.

Define Python domain models for notes, review events, scheduling state, and reminder status without coupling them to FastAPI or PostgreSQL.

Design a PostgreSQL schema with keys, constraints, timestamps, indexes, and vector columns that support review history, due-item queries, and semantic retrieval.

Apply a versioned SQL migration to create or modify the PostgreSQL schema safely.

Load and validate environment-specific configuration and secrets for a local FastAPI application.
