# Trust proof: Mode respects design-system/component constraints in a real workflow
## User belief to change
AI UI tools create plausible-looking garbage because they ignore our component library, tokens, variants, states, and engineering constraints.
## Current environment
Many AI design/code tools can generate or edit UI in isolation, but mature teams need proof that output respects existing systems and review paths. For higher-ACV ICPs, trust is less about magic and more about governance.
## Why this matters
This is not the first proof for broad launch, but it may be the proof that makes Mode credible to mature design-system or engineering stakeholders.
## Aha moment
Mode makes a scoped change that visibly uses the correct existing component/pattern/variant and produces output engineering can review against the system.
## What to show
Existing component or token/pattern context -> selected UI change -> Mode uses/preserves the right component/pattern -> output includes enough evidence for reviewer to validate fidelity.
## Belief gates
- Component traceability: viewer can see which existing component/pattern is used.
- Variant/state awareness: if relevant, the proof shows a real state/variant constraint rather than a static happy path.
- Engineering reviewability: output gives engineers/design-systems people something inspectable.
- Scoped claim: Mode does not claim blanket design-system fidelity unless the demo proves it.
## Pass criteria
The proof can withstand a skeptical design-systems/frontend review. It shows exact scoped fidelity, not broad unsupported design-system claims.
## Failure modes
Random component output; broad “design-system faithful by default” language; no traceability; only aesthetic similarity; no engineering-review artifact.
## Claim unlocked
Mode can preserve/use existing component context in scoped product changes, with reviewable output.
## Evidence basis
- Mode W5: design-system fidelity as trust layer
- ICP trigger: AI tools breaking design-system consistency
- Mode W6: review path required for credibility

## Priority note
This is a second-order proof for design-system/enterprise credibility, not the launch hero unless the target audience is explicitly design-system-heavy.
