Engineered Contract Packs

Skip the setup. Start from a production system.

CogentStack defines 33 project-type contracts. Website v2.0.0 is the first fully executable Contract Pack; the proposed AI v3.0.0 generation is the next engineering direction. An executable pack instantiates the technical foundation, validation, acceptance evidence, and release process for its project type.

27project-type contracts and counting

Website Contract Pack v2.0.0 contains

  • Starter application
  • General and showcase patterns
  • Pinned contract binding
  • Selected project profile
  • Semantic application shell
  • Responsive safeguards
  • Accessibility controls
  • Foundation test suite
  • SEO discovery routes
  • Acceptance evidence map
  • Local launch automation
  • Release recipes
  • Content release gate
  • Local, private, and public modes

A curated, opinionated production library with an AI operating layer

Repeatable work should not restart from zero.

Freelancers and agencies rebuild authentication, administration, security controls, test harnesses, and deployment configuration across the same categories of project. CogentStack starts with those decisions engineered and the acceptance criteria already defined, turning time saved into something measurable rather than a vague claim about better guardrails.

Evidence, not assertion

Inspect the evidence that makes Website v2.0.0 release-ready.

These sanitised diagrams come directly from the current Website Contract Pack structure, acceptance map, foundation tests, and release checks. Protected contract rules remain server-side; the production evidence does not.

01

Generated architecture

What the pack instantiates

  1. Contract pin.coge/contract-binding.json
  2. Selected profile.coge/project-profile.json
  3. Website foundationapp/ + components + configuration
  4. Acceptance evidence.coge/acceptance-map.json
  5. Release recipe.coge/release-recipe.json

The contract version and checksum are pinned. A mismatched Contract Pack stops rather than presenting an incompatible build as compliant.

02

Verification architecture

What blocks an incomplete release

  1. Build and foundation testsDeterministic source, semantic structure, keyboard readiness, and rendered output.
  2. Accessibility and discoveryResponsive safeguards, focus visibility, reduced motion, robots, sitemap, and not-found recovery.
  3. Content release gateStarter content, missing assets, and unresolved decision markers block release.
  4. Controlled release modeLocal, private, or explicitly confirmed public deployment.

Architectural difference

Direct dialogue.Governed delivery.

CogentStack keeps you in direct conversation with the AI while an approved project contract provides the structure, requirements, controls, and acceptance criteria alongside that conversation.

01

Agentic builders

The agent mediates the work.

Platforms such as Replit-style builders place an AI agent inside their own execution environment. The agent edits files, runs commands, maintains working state, and reports through the platform's agent loop.

02

CogentStack

The contract governs the work.

You discuss refinements naturally with the AI rather than routing every change through a separate builder agent. The contract keeps delivery controlled without becoming a translation layer between you and the model.
