Subject: [PATCH] Stage 1 rubric: drop domain-match, align to docs/SPEC.md
 scope
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first real Layer 3 visual smoke produced an iOS Stage 1 FAIL —
not because of a rename bug, but because Stage 1 captured the
substrate's onboarding screen ("Onboarding 1 / Landscape /
Onboarding description 1") and the rubric's domain-match criterion
("does this read as a clinic queue?") asks a question Stage 1 can't
answer until mobile-mcp navigation lands.

Per docs/SPEC.md, Stage 1's stated purpose is catching "egregious
rename failures" (substrate-leak), and Stage 2 — UI-driven
navigation past onboarding/login via mobile-mcp — is where
domain-semantic UI judging belongs. The current rubric overreaches
into Stage 2 territory at Stage 1.

Changes:
  - DEFAULT_STAGE1_RUBRIC: drop domain-match. Keep no-substrate-leak
    (Stage 1's actual job per SPEC.md) and renders-cleanly (broad
    enough to catch crash/layout breakage on any screen including
    onboarding placeholders).
  - tests/smoke.test.ts: update the assertion to match new IDs.
  - docs/SPEC.md: re-pin domain-semantic question to Stage 2,
    explicitly call Stage 1 "substrate-leak detection and render
    sanity." Resolves an internal inconsistency that pinned the
    domain question at Stage 1 vs. its declared Stage-1 scope.

Out of scope: Stage 2 (mobile-mcp navigation past onboarding to
the actual domain UI). That's where domain-match belongs and is
the eventual full demo. Significant feature, separate PR(s).

Verification:
  - npm run ci: 19/19 green.
  - Real-mode visual run on the next attempt should show
    Layer 3 2/2 pass on iOS (onboarding placeholder satisfies both
    no-substrate-leak and renders-cleanly).

+- For UI specifically, Opus 4.7 vision reads the simulator and emulator screenshots captured in Layer 2. **Stage 1** scores the post-launch screen for substrate-leak detection and render sanity (catches "the app still says 'Shop' everywhere"). **Stage 2** navigates past onboarding/login via mobile-mcp to the actual domain UI and scores: "does this screen read as a [clinic queue / restaurant waitlist / task tracker] to a real user?"
 
 Guardrails against known LLM-as-judge weaknesses:
 - Rubrics are structured Yes/No-per-criterion, never free-form scoring, to reduce the "well, I guess that's fine" drift LLM judges default to.
