+# IB-WP-0002 — Infospace Lifecycle Baseline
+
+## Goal
+
+Implement the first file-backed baseline for creating, loading, updating,
+inspecting, and exporting infospaces.
+
+## FRS Coverage
+
+- FR-001 to FR-004: infospace lifecycle
+- FR-010 to FR-012: knowledge artifact population
+- FR-020 to FR-021: structure and relationships
+- FR-070 to FR-071: export and derived artifacts
+- FR-090 to FR-091: structured errors and explicit failures
+
+## Tasks
+
+### T01 — Define repo-local infospace layout
+
+```task
+id: IB-WP-0002-T01
+status: todo
+priority: high
+state_hub_task_id: "c8aaa52e-db89-42e3-9ebc-cb89be3f4d30"
+```
+
+- Define `infospaces/<slug>/infospace.yaml`
+- Define artifact, output, evaluation, metrics, and report directories
+- Document required and optional files
+
+### T02 — Define configuration model
+
+```task
+id: IB-WP-0002-T02
+status: todo
+priority: high
+state_hub_task_id: "a96c3439-89e4-40d0-8731-fe6b39a8f451"
+```
+
+- Reimplement the useful `markitect/infospace/config.py` concepts
+- Keep references to schemas, workflows, sources, disciplines, and viability
+  thresholds explicit
+- Avoid importing runtime orchestration concerns
+
+### T03 — Implement artifact model and loader
+
+```task
+id: IB-WP-0002-T03
+status: todo
+priority: high
+state_hub_task_id: "36ad8a84-f4fd-48ca-bc6f-94827ac03481"
+```
+
+- Model artifact identity, source path, type, provenance, and relationships
+- Support deterministic loading from file-backed projects
+- Return structured errors for invalid layouts
+
+### T04 — Add lifecycle CLI
+
+```task
+id: IB-WP-0002-T04
+status: todo
+priority: medium
+state_hub_task_id: "bfa70d92-c896-4133-8b93-0ece3e53c649"
+```
+
+- Provide minimal commands for create, inspect, add-artifact, and export
+- Keep command outputs scriptable and traceable
+
+## Acceptance
+
+- A new infospace can be created from a template
+- An existing infospace can be loaded and inspected
+- Artifacts can be added and listed
+- Invalid configs produce structured, visible errors
