Python labs

Zero-key, in this repository

• python3 labs/01-local-hello.py — local runner or an honest mock.
• python3 labs/02-tool-call.py — a sum from a tool.
• python3 labs/03-golden-eval.py — a fixed ten-question file.
• python3 labs/06-rag-ablation.py — one fixture, keyword versus a naive neighbor.
• python3 labs/07-agent-loop.py — a correction and a stop.
• python3 labs/08-voice-latency-budget.py — a stage p95 on toy milliseconds.

No key is required. A missing local model is reported as a mock. These scripts are the worked examples the rooms point at. The milliseconds in lab 08 are a teaching fixture.
