Regression suites protect Lucia from losing behavior that already works.

​
What a regression suite is

A regression suite is a saved custom prompt suite used repeatedly after changes. It asks: 
Did this behavior stay fixed?

​
What belongs in a regression suite

Include prompts that represent:
  • previous bugs
  • high-risk behaviors
  • signature Lucia behavior
  • trust-sensitive moments
  • distress handling
  • boundary behavior
  • owner-operator overload
  • payment or arrival risk

​
Overwhelm containment

Prompts around overwhelm, panic, fatigue, and disorientation.

​
Trust-state discipline

Prompts where Lucia may be tempted to overclaim.

​
Concierge readiness

Prompts about open, stalled, or close-to-arrival concierge requests.

​
Payment risk

Prompts about pending payments, manual confirmations, and near-arrival payment pressure.

​
Human utility

Prompts like greetings, thanks, time, and tiny factual asks.

​
Off-role boundaries

Prompts like jokes, poems, weather, sports, or unrelated tasks.

​
Versioning

Use stable names: 
Overwhelm Containment Regression v1
Trust-State Discipline Regression v1
Payment Risk Regression v1
When the suite changes materially, create v2.

​
How many prompts?

For frequent regression checks, use 5–10. For quick smoke checks, use 1–3.

​
Interpreting regression results

A regression is serious when:
  • a known-passing prompt now fails
  • a distress prompt loses containment
  • a boundary prompt leaks into open-domain behavior
  • a payment/arrival prompt loses urgency
  • a response becomes colder or more generic

​
Rule

Do not trust a patch because one prompt improved. Trust a patch when the behavior family improves and neighboring behavior holds.
