 ### Added
 
+- Authenticated loopback research API and OpenAPI definition, protected provider settings/capability tests, pinned inert skill installation, Crossref metadata/source tools, scoped public-page permissions and persisted AG-UI replay.
+- Economics/English and humanities/Chinese live DeepSeek/Crossref metadata research, report revision and archive round-trip smoke tests; full-text and browser acceptance remain pending.
 - Initial TypeScript platform archive, generic single-agent Harness, supervised IPC worker and streaming model adapter, with confirmation, interaction validation, cancellation, restart reconciliation and immutable report archives.
 - Native Windows core tests, strict type checking and an explicit opt-in DeepSeek streaming/tool-call smoke test. Application UI, retrieval and full research acceptance remain pending.
 - Research workspace specification covering conversation, execution state, live artifact revisions, evidence navigation, responsive layouts and application acceptance scenarios.

 OpenLab is a local-first research workspace being designed to connect open research tools, AI agents, literature, data, and compute. Research projects and their evidence belong to the researcher and should remain usable when a model or tool changes.

+- Metadata confirms that a provider returned a record; it does not verify a paper's claims.
+- Fetched public page content may be an abstract or landing page. State exactly what was accessed.
+- Preserve empty results, conflicting records, failures and inaccessible full text.
+- Mark model interpretations as unchecked. A source title alone cannot support a conclusion.
+- Cite the platform source identifier and preserve source/run/step provenance in the research archive.
