hermes-code-demo

Deterministic source-defect fixture for the Hermes automated triage demo.

src/discount.py holds one small pricing helper covered by tests/test_discount.py. The demo introduces a one-line defect on a branch, Jenkins fails the test gate, Ariadne collects the evidence, and Hermes proposes a minimal patch that Ariadne validates and pushes as a pull request for human review. Nothing merges automatically.
