Brand & Identity

What it is: the building and governing of the brand SYSTEM — the strategic core, the verbal + visual + sonic identity, the guidelines/design system, the trained/governed brand model, and the high-stakes brand decisions (brand-vs-demand, rebrand-vs-refresh). Brand is the home; brand consistency applied everywhere else is the continuous brand THREAD, not this section's content.
The 2026 shift: brand governance is moving from a PDF a human consults to a machine-readable system an AI/agent reads at the moment of creation — design tokens, a machine-readable voice spec, a brand-fine-tuned model, and brand-as-MCP (MCP = Model Context Protocol, the machine interface AI tools and agents use to call a brand's systems and guidelines directly), gated by automated brand-score checks.
The hard truth: Brand's evidence base is contested, not settled — the 60/40 brand-vs-demand rule, the 95-5 rule, and "distinctiveness > differentiation" are all live disputes (Binet/Field/IPA vs Ehrenberg-Bass/Sharp; Ritson; Thomaz). Use the evidence to inform the brand decisions, never to settle them.
Don't: treat 60/40 as a constant, let consistency engines optimize you into "blanding," cite the fabricated "31% archetype engagement" stat, or let the thin agent-pole carry structural weight.

How this domain is organized internally — and the decision logic, runnable workflows, and agent angle — are in the full map.
