• The app searches only the current tenant's requirements and documents. pgvector finds the relevant passages. Zod checks the draft and gives the model one repair attempt when the shape is wrong.
• Four roles control what each person can see and do. PostgreSQL RLS adds a database check. A manager must approve the plan before it becomes tasks.
• Files go to S3 and jobs run through SQS. Failed jobs retry before moving to a dead letter queue. The app keeps an audit record and tests 15 cases across three prompt versions.

The demo uses seeded synthetic data and fixed test cases.

• Health checks use rolling windows. A failing connector opens an incident, and the investigation cites the events behind each finding.
• Patient details are removed before the model sees them. A separate check looks for anything the first pass missed.
• A reviewer approves recovery. Pulse checks the target again at that point. Incoming events use HMAC signatures, duplicate events are ignored, and queued jobs follow Retry-After responses.

The demo uses synthetic healthcare data and simulated connectors.

• The model extracts fields from a PDF and returns the source page with each value. The demo can use a fixed local model response or Claude.
• Application code decides where the case goes. Missing fields, contradictions, and text that looks like a prompt injection send the case to review.
• Processing and export are safe to retry. Every status change is recorded. The evaluation set has 60 synthetic packets.

The demo uses synthetic data. Clinical decisions stay outside the project.

• Market quotes are cached for a short time. When the data provider is unavailable, the demo switches to a fixed fallback data set.
• Buy and sell rules reject orders that exceed the available cash or shares. Cost basis uses a weighted average. The chart rebuilds account value from the transaction history.
• The app runs in Docker with PostgreSQL on Render. Database setup can run more than once safely, and pytest covers the trading logic.

This is my solo rebuild of a team capstone idea.
