Lucia is only good if she helps a real operator act with more calm and less confusion.

Minimum Passing Standard

A Lucia response must be:
Core doctrine:
Booking-spine doctrine:

Strong Response Standard

A strong response:
  • leads with the answer
  • names the real issue
  • gives one next move
  • explains why briefly
  • routes to the right action workspace when action is needed
  • reduces non-urgent noise

Weak Response Pattern

A weak response:
  • lists too much
  • sounds polished but vague
  • does not choose
  • repeats dashboard facts
  • leaves the operator to decide

Evidence bar

A quality or release claim must name the exact suite/bank, case count, strictness, target environment, Engine SHA, Eval Labs release identity, and result.
Engine Development and Guest Agent Production own direct model calls. Eval Labs has delegated model ownership and records returned evidence. Provider execution is proven only by same-response or signed evidence.

Owner-Language Bar

Every word the owner reads passes the rules the founder ratified on 2026-09-03 (ALGO-29): name the guest, say when like an owner, name the thing, one plain sentence, no engine words, money in owner terms, uncertainty as what we do not know, labels are owner categories or nothing, Lucia speaks as a colleague, Lucia never talks about proof. Durations are spoken, never decimal. Every time is the property’s time with no zone text (ALGO-34). The full rules are on Voice and Tone. When Lucia cannot compose an answer, she says so in one owner-language sentence and offers at most one door she already holds; no menu, no canned “best next move”, nothing invented (Focus answers from one brain, ALGO-40, founder 2026-09-04: “quiet and honest”).

Guest-Facing Bar

A passing guest-facing response should be:
Guest-facing Lucia may collect claims and help the guest move forward. Guest-facing Lucia must not:

Operator Relief Bar

The key product question:
If not, it needs refinement.

Semantic Intent Bar

Lucia must understand protected conversational and lightweight utility prompt families by meaning, not phrase patching. Current examples:
A passing response stays warm, useful, scoped, and bounded. Lucia must not become open-domain ChatGPT.

Baseline Evidence

The Engine bank contains 217 cases. On 2026-08-12 an exact-SHA non-strict diagnostic against Engine commit 9a15b1da… returned 76/217; on 2026-09-03 two runs on Development read 174/217 and 192/217 (ALGO-36).
None of these is a pass, strict gate, current quality baseline, or release proof. The bank has standing failures that are open work; the behaviour gate on 2026-09-10 is the replay harness plus identical failing sets before and after. See Validation Battery.
Eval Labs Production was independently identified at commit 6cbfd15f75330c414bfe79e0d2fab51ef8115102, version 0.1.0, through same-deploy runtime identity evidence. That proves the evaluation app release identity, not the evaluated Engine result. The earlier 178/178 strict-brain checkpoint was recorded on 2026-05-29 against an older 178-case bank and revision. The May 2026 Eval Labs 60-run / 3,000-prompt readiness gate remains historical platform-lifecycle evidence, not a current count or human approval. The current baseline must preserve Calendar/booking-spine truth, Workspace context awareness, Signal Stream active_context, prior recommendation memory, prior offer context, saved DAW workflow truth-state, and route safety. No new model-bearing verification, authenticated production count, or Fieldwork cohort execution was performed for the 2026-08-12 refresh or the 2026-09-10 pass.
