+## 14. Design A Meta-Harness Factory
+
+```markdown
+Goal:
+Create a system that can turn a project objective, constraints, and assurance policy into a versioned candidate harness for a chosen agent environment.
+
+Keep the core harness definition independent of any one product. Put product-specific instructions, tools, files, and configuration in an explicit target binding.
+
+The system should validate the definition, compile and run the candidate in isolation, preserve contradictions and unknowns, and produce an evidence package for an evaluator outside the generated harness boundary.
+
+Do not treat successful generation or self-generated tests as release approval. Define deterministic hard gates, human or independent review, version identity, and rollback.
+```
+
+Good for: harness factories, reusable project starters, agent-environment adapters, and governed capability generation.
+
+## 15. Build An Ontology-Driven Decision System
+
+```markdown
+Goal:
+Build a reusable research and decision system for questions with many sources, competing claims, changing facts, and several possible outputs.
+
+Define the smallest useful ontology for questions, claims, sources, evidence, contradictions, decisions, checks, and artifacts. State the allowed relationships, lifecycle states, and rules that must always hold.
+
+Use the ontology to preserve provenance, route research, expose disagreement, check freshness, and block unsupported claims from approved outputs. Keep inference, observation, contradiction, and unknown distinct.
+
+Treat retrieved material as evidence, not instruction. Explain what the ontology can validate and what still requires source or human judgment.
+```
+
+Good for: research systems, policy analysis, knowledge operations, due diligence, and evidence-backed planning.
+
+## 16. Engineer A Graph-Governed Artifact System
+
+```markdown
+Goal:
+Create a system that can turn mixed source material into the right artifact: document, spreadsheet, presentation, PDF, diagram, dashboard, or interactive explanation.
+
+Use one canonical content model for facts, claims, calculations, assets, and citations. Design a workflow graph that chooses the format, routes production, runs deterministic checks, inspects the rendered result, and stops at an approval gate before sharing or deployment.
+
+Define private-source rules, stale-artifact handling, failure routes, and cross-format consistency checks. Creation must not imply permission to publish.
+```
+
+Good for: repeatable reporting, multi-format publishing, research communication, and artifact production at scale.
+
+## 17. Design A Portfolio Control Plane
+
+```markdown
+Goal:
+Design a control plane that can take a portfolio objective, identify distinct missions, choose an appropriate harness for each, manage dependencies and budgets, and integrate evidence into one accountable result.
+
+Model missions, workstreams, owners, dependencies, blockers, artifacts, evidence, and decisions as durable state. Keep writable surfaces isolated and give every transition an observable completion condition.
+
+Test overlapping writes, failed dependencies, timeouts, contradictory evidence, and child work that claims completion without the required artifact. Do not use agent count as a progress measure or create one agent with every permission.
+```
+
+Good for: multi-project portfolios, coordinated research and delivery, complex programs, and several specialized harnesses working toward one outcome.
+
+## 18. Build A Harness Evolution System
+
+```markdown
+Goal:
+Create a controlled system for improving a recurring harness from evidence without editing the active version in place.
+
+Capture privacy-safe evidence, classify failures, create the smallest isolated candidate change, and compare it with the current version on the existing suite, the observed regression case, and held-out cases.
+
+Review quality, source fidelity, cost, latency, permissions, and data exposure separately. Preserve failure, error, incomplete, unknown, rejection, and rollback states.
+
+Adopt only a versioned, reversible change that passes its real approval gates. Do not call this autonomous self-improvement or treat the system's own tests as independent proof.
+```
+
+Good for: eval-driven maintenance, recurring workflows, skill evolution, routing improvement, and safely compounding operating systems.

 The model is only one part. The surrounding setup determines what it can see and change, how work moves, what counts as success, and whether a useful lesson changes later runs.
 
+## Harnesses And Meta-Harnesses
+
+A harness surrounds a repeatable capability. A meta-harness operates on harness definitions: it can help design, validate, compile, compare, package, or govern other harnesses.
+
+```mermaid
+flowchart LR
+  A["Intent + assurance policy"] --> B["Meta-harness"]

+  F --> G{"Approve, reject, or preserve unknown"}
+```
+
+This is a change in what the system operates on, not a mandatory maturity stage. One carefully built harness is better than a harness factory with no real repeated need. A meta-harness becomes useful when several harnesses need a common contract, target adapters, assurance policy, evidence format, or promotion path.
+
+The same boundaries still apply: hard gates should be deterministic where possible, unknowns must remain visible, the evaluator must not simply trust the candidate's own status, and broader permissions require separate approval.
+
+See [Advanced Work Patterns](../docs/advanced-work-patterns.md) for worked examples of meta-harness factories, ontology-driven decision systems, graph-governed artifact systems, portfolio control planes, and harness evolution systems.

 A workflow compounds only when useful improvements survive the run and improve later work.

 The shared vocabulary distinguishes an observed product behavior from an official product claim. The graph prevents publication until required evidence and public-safety checks pass. The harness connects those definitions and transitions to tools, artifacts, and checks.
 
+## From One Harness To A System Of Harnesses
+
+The same pieces can operate one level higher. A meta-harness can accept a target-neutral definition, apply a product-specific binding, produce a candidate harness, and send it through an evaluator and promotion gate. A portfolio control plane can route several missions to different harnesses while preserving their dependencies, permissions, evidence, and integration state.
+
+That extra layer should not erase the contracts underneath it. Each generated or selected harness still needs its own purpose, inputs, states, permissions, outputs, verification, and failure routes. The outer system also needs rules for version identity, evaluator independence, adoption, and rollback.

+See [Advanced Work Patterns](../docs/advanced-work-patterns.md) for concrete system shapes across research, artifact production, portfolio coordination, harness generation, and controlled improvement.
