Design engineering
04- 01PracticeAcceptance criteria are part of the interfaceDescribe completion through observable behaviour, useful recovery and a small set of reviewable checks.2 min
- 02Design SystemsTypography as interface architectureHow five semantic type registers separate editorial narrative, reading, interface, technical evidence and runtime state without fragmenting the system.2 min
- 03PracticeDesign engineering without the handoverWhy strategy, interface, implementation and verification stay in one accountable thread—and where that model fits.7 min
- 04Interface SystemsInterfaces beyond the screenHow clear task state, familiar controls and deliberate approval points support interfaces that combine conversation and direct interaction.2 min
System architecture
06- 01MethodsThe website is a renderer, not the source of truthEntities are validated once, relationships resolved once, and every public representation is compiled from that graph — the website is one renderer among several.5 min
- 02MethodsFour pillars of a machine-surface scoreFindability, Quotability, Structural integrity and Trust form a bounded vocabulary for deterministic public diagnostics — a score summarises evidence; it does not replace it.5 min
- 03ArchitectureWhy machine-readable architecture is not structured data aloneA machine-readable system depends on crawl access, semantic structure, entity coherence and operational evidence—not JSON-LD in isolation.6 min
- 04MethodsDesigning deterministic website diagnosticsHow bounded checks, inspectable evidence and transparent scoring produce diagnostics that remain useful after the headline score.2 min
- 05Agent SystemsChoose the smallest useful agent workflowA practical way to separate predictable work from decisions that need interpretation, then add coordination only where it helps.2 min
- 06Agent SystemsCoordinate tasks before adding agentsHow task ownership, explicit state and completion checks make a multi-agent workflow easier to operate.2 min
Operational systems
05- 01Operational AIAuthority, execution and evidence in operational AI systemsA practical separation between deciding what may happen, executing bounded actions and proving the resulting state.8 min
- 02InfrastructurePrivate networking for agent systemsDefine the connections an agent needs, control outbound access and verify the boundaries between environments.1 min
- 03InfrastructureNetwork topology is an authority modelUse network design to make ownership, permitted connections and inspection points clear.1 min
- 04InfrastructureSet the baseline before adding workloadsEstablish access, connectivity and operating rules before applications depend on an environment.1 min
- 05SecurityBuild a security foundation in stagesConnect ownership, access controls, deployment checks and recovery into a practical operating routine.1 min
