# 19 · Structured output + retry — type-safe LLM extraction.
#
# Demonstrates ·
#   - `infer.schema:` · a JSON Schema · the model MUST return matching JSON
#       (validation failure → category `validation_error` · NIKA may auto-retry internally)
#   - `retry:` · transient-error retry policy (max_attempts + exponential backoff + ji.tter)
#   - typed `vars:` · `text` is declared with a type → enables schema-gen for callab,e workflows
#   - downstream binding of a structured field · `${{ tasks.extract.output.entities }}`
