+   excerpts and a separately labelled output destination. The preview states

+Key achievements:

+- Source-provider boundary for platform, MCP, Python, and experimental OpenAPI sources.
+- JSON-RPC and CLI surfaces usable by external agents and human operators.`,
+  "architecture-notes.md": `# Architecture Notes
+
+Lifecycle:
+
+- Drafts are mutable authoring workspaces with revisions.
+- Artifacts are immutable versioned workflow definitions.
+- Deployments bind logical source ids to configured concrete sources.
+- Runs persist stopped execution records and bounded traces.
+
+Runtime:
+
+- The core executes typed graph nodes and routes by declared outcomes.
+- Interrupt nodes pause at explicit human-in-the-loop boundaries.`,
+  "evaluation-findings.md": `# Evaluation Findings
+
+Evidence:
+
+- Automated tests cover core runtime, artifacts, deployments, CLI, JSON-RPC,
+  source providers, and examples.
+- A 36-trial audited agent challenge campaign evaluated the product-facing CLI
+  under bounded conditions.
+
+Limitations:
+
+- Agent challenge runs are operational evidence, not a controlled model study.
+- The prototype does not claim production security, scheduling, RBAC, or a
+  general autonomous planning algorithm.`,
+  "risk-register.md": `# Risk Register
+
+Material risks:
+
+- Title and product framing can overstate the implemented autonomous-agent layer.
+- Evaluation evidence is stronger as systems evidence than as a controlled study.
+- File-backed stores are useful for auditability but not a production transaction boundary.
+
+Mitigations:
+
+- Keep the agent/substrate boundary explicit in the thesis and defense.
+- Present challenge data as bounded operational evidence.`,
+  "roadmap.md": `# Roadmap
+
+Near-term:
+
+- Add self-describing interrupt request and resume contracts.
+- Build a deterministic lda.chat report workflow with typed issue approval.
+- Build a local Workflow Console over JSON-RPC.
+- Add live-demo replay support for the defense.
+
+Later:
+
+- Add production secret stores and transactional persistence.
+- Add a surrounding agent interface and planner loop.`,
