Deterministic assertions

Use exact checks wherever the evidence permits them, and reserve narrow semantic rubrics for the places where language interpretation is genuinely necessary.

Deterministic assertion packs are engineering-owned and optional. They are referenced from the config alongside workflows and rubrics:

test_suite:
  workflows:
    - generated/workflows/block_card_placeholder.workflow.yaml
  rubrics:
    - generated/rubrics/block_card_placeholder.acceptance.rubric.yaml

Because assertions are evaluated against saved evidence, you can change them and re-score an existing run without calling the agent again — see replaying evidence.
