IDENTITY / VERSION 1.1 / OCTOBER 2026

Clear authority.
A considered identity.

A precise, calm identity for agents that act in business systems. The shield-R signals an explicit boundary. Violet brings possibility; ink brings clarity.

PNG marks are supplied at 64, 256 and 512 pixels. Outlined wordmarks are included in every variant.

02 / COLOUR

A restrained, readable palette.

Ink #25283B Primary text and dark surfaces
Violet #6950C7 Identity and emphasis
Ivory #F7F5EF Primary light surface
Lilac #E6DFF6 Supporting light surface
Muted ink #625E70 Secondary text on light surfaces

Use ink or muted ink for small copy on ivory and lilac. Use ivory or white on ink. Use violet on ivory for emphasis. Check contrast when pairing colours; pale accent colours are surfaces, not small text. Status must always include a readable label.

03 / TYPE & SPACE

Room for the important part.

Plans change.
Authority should change too.

Interface and editorial type use the system sans-serif stack: Inter when available, then ui-sans-serif, system-ui, Apple and Segoe UI fallbacks. No remote font request is required. Use ui-monospace for identifiers and technical labels.

The supplied wordmark is outlined from DejaVu Sans Bold and Regular for consistent reproduction. Use the vector master rather than retyping it.

04 / USE WITH CARE

Keep the boundary clear.

Logo inside its reserved clear space

Leave at least half the shield’s width clear on all sides. Keep the standalone mark at least 24px wide and the full logo at least 140px wide on screen. For tiny favicons use the supplied mark.

Do

  • Use an approved light, reverse or mono file.
  • Keep original proportions and clear space.
  • Place the logo on a quiet, contrasting surface.

Don’t

  • Stretch, rotate, recolour or separate the R from its shield.
  • Add shadows, gradients, borders or extra symbols to the logo.
  • Place it over busy imagery or imply a certification badge.
05 / VOICE & POSITIONING

Specific. Calm. Accountable.

Explain the action, the boundary and the observable result. Use plain verbs and concrete limits. Sound like a thoughtful technical partner. Describe what exists today separately from what a future integration could support.

SAY

“Plans change. Authority should change too.”

“For automation agencies and technical teams building agents that write to business systems.”

“RuleEvo checks scoped authority before admission in integrated workflows.”

“Withdraw future authority. Separate blocked, completed and unresolved work.”

“A bounded prototype seeking design partners.”

AVOID

Promises beyond the boundary.

No “every agent must pass through us,” “instant global stop,” “guaranteed undo” or “Google-certified.”

No invented customer logos, independent audits, uptime promises or claims of proven customer demand.

Use “Starter” for the small-entry commercial catalog. The local illustration and downloadable JavaScript client are free; live integrations remain invite-only. Do not imply self-service hosted access, free live accounts or included human support. Merchant approval and payment setup remain pending.

06 / SHARE

A clean first impression.

Use the 1200 × 630 card for link previews and introductions. It is a brand card, not a product screenshot or evidence of customer outcomes.
