What the research says
Reaching a given model capability now costs a small fraction of what it did, yet MIT NANDA's preliminary findings say few custom enterprise tools reach production. The cost has moved from the model to the system around it, so Naevum builds that system first: a protected core, a replaceable harness and components that carry their contracts.
A model can answer correctly while its application loses approvals, repeats a tool action or fails when another team takes over. Our development architecture carries the same objective through planning, implementation, independent challenge and the exact delivered artifact.
Black Box defines the delivery responsibilities. Agency Engine supplies application controls and product seams. Conductr separates the coding harness into replaceable components. The Vault checks the assumptions carried by reusable engineering. Together they give a custom system an architecture for how it is built as well as how it runs.
The factory design begins with an owner-confirmed scope, permitted effects, budget and expiry. An independently authored acceptance condition precedes implementation.
Coder, reviewer and QA responsibilities are separated. Findings refer to the source they examined, so a correction changes what must be checked.
A handover packet retains decisions, findings and the next unresolved obligation when an attempt ends.
Agency Engine separates the kernel, service kit, UI hooks, component kit and screens from the product-owned shell. Imports point towards the foundation; product-specific composition sits above it.
Gate and decision logic, the ledger, write boundary, capabilities, evidence, approvals, model admission and connector/store custody form the sealed set. The architecture declares these services non-replaceable. A closed-list startup guard and contract tests check the declared bindings; this is not process isolation or protection against arbitrary new bindings.
Product composition and requested capabilities.
An application whose permitted extensions have explicit boundaries.
Engine defaults, product configuration, installation, organization and workspace or seat merge in that order. A lower layer may tighten inherited policy.
Versioned defaults plus local context.
The effective policy for that installation.
A local preference cannot grant a capability denied by an earlier layer.
Services declare whether they belong in the client or a separately operated cell. Versioned packages and per-layer software bills of materials define a release independently from a product’s appearance.
Selected service contracts and package versions.
A product dependency graph and upgrade boundary.
The client/cell tag describes the boundary; actual placement belongs to the deployment profile.
Agency’s semantic orchestration design separates task/output contracts from individual attempts. A typed dependency graph drives readiness; journal replay reconstructs work state without another reasoning call. An uncertain effect blocks automatic reissue.
A versioned intent graph, prior events and declared output contract.
Reconstructed task state, eligible work and retained unresolved effects.
Exactly-once external consequences require matching support at the effect sink.
The VP of engineering accepts the system; a reviewer who did not build it runs the tests. Illustrative.

A new application needs its own workflow, language and interface.
The Vault’s composition checker carries assumptions as data. Matching a function signature does not establish that two components agree about timing, order or who owns a resource.
Typed ports connect sequential or concurrent components. Request/offer checks compare cadence, ordering and whether a value may be absent.
Feedback closes a declared loop; a wrapper adapts a component’s environment. Assumptions that neither a neighbor nor the environment satisfies remain obligations of the composition.
Conductr defines a context engine, planner, orchestrator, executor, sandbox, router, verifier, policy gate and event store as interface-bounded slots. The orchestrator coordinates their order; a component can be replaced without pretending its responsibilities disappeared.
A work node names files, the intended change, forbidden changes and an acceptance test. The executor works against that external oracle.
A manifest node and seeded repository.
An edit and its acceptance result.
Verifier findings and trust events are observed separately from the agent’s ongoing context. A policy gate may act at the commit boundary.

Conductr’s degrading integration seams are distinct from Synapse’s disclosure-admission controls.
The proving-ground manifest fixes task battery, model, context strategy, repetitions and seed basis for baseline and treatment. Gated metrics and tracked metrics have separate roles.

A measured harness improvement is specific to that experiment.
In an illustrative composed workflow, an institution commissions document review with a restricted appendix and two approval roles.
The application composition defines the two roles and protects the model door. Synapse supplies the context-admission boundary. A work package names the permitted document view, expected review artifact and interrupted-request recovery. Independent acceptance follows the candidate’s exact source, while the handover retains unresolved findings and the operating procedure.
This is how the technology enters a custom engagement: a concrete workflow assembled from explicit controls and individually understood dependencies. The factory triad is the selected delivery design; its automated execution is qualified separately for each project.
Inputs, retained state, outputs and limits of Naevum’s Software development architecture.
The contribution is the surrounding architecture: protected application controls, contract-aware reuse, independent acceptance, replaceable execution components and durable delivery records. These mechanisms connect a business workflow to an inspectable system.
The application foundation supplies shared governance and selected services. Domain logic, interfaces, integrations, local policy and acceptance conditions belong to the engagement. Factory automation and deployment boundaries are qualified for the named project.

Works withContracts and evidence for composition.
The Vault’s assume–guarantee checker carries unfulfilled assumptions outward. Its request/offer checks cover cadence, absence and ordering. That addresses architectural mismatch beyond matching data types.
Architectural mismatch and assume–guarantee reasoning are established research foundations; Naevum’s contracts and composition rules are the engineering implementation described here.
The Black Box triad is the selected factory design. Agency package seams, Conductr’s component assembly and Vault composition have their own contracts and implementation evidence. Automated factory acceptance remains project-specific.
A custom engagement binds its source, deployed configuration, acceptance conditions and operating evidence. No generated code count or general harness benchmark replaces that contract.
