|----------------|---------------------|-----------| | **API Calls** | Parallel (rate-limited) | Maximize throughput within limits | | **PDF Downloads** | 5 concurrent connections | Balance speed vs. server load | | **LLM Summarization** | Sequential | Control token costs, avoid rate limits | | **Provenance Logging** | Async (non-blocking) | Don't slow primary operations | | **File I/O** | Sequential with mutex | Prevent corruption | ```typescript // Concurrency configuration const ConcurrencyConfig = { api: { semanticScholar: { maxConcurrent: 5, rateLimit: 100 }, // 100 req/min crossRef: { maxConcurrent: 3, rateLimit: 50 }, arXiv: { maxConcurrent: 2, rateLimit: 30 } }, download: { maxConcurrent: 5, retryAttempts: 3, exponentialBackoff: [5000, 10000, 20000] // ms }, llm: { maxConcurrent: 1, // Sequential to control costs timeout: 120000 // 2 minutes per request }, provenance: { mode: 'async', bufferSize: 100, // Buffer before flush flushInterval: 5000 // 5 seconds } };

Key Architectural Decisions ### 5.1 ADR Summary Table | ADR | Decision | Status | Rationale | |-----|----------|--------|-----------| | ADR-RF-001 | File-based storage over database | Accepted | Solo developer, Git-friendly, portable | | ADR-RF-002 | Agent-per-stage architecture | Accepted | AIWG alignment, separation of concerns | | ADR-RF-003 | W3C PROV for provenance | Accepted | Interoperability, academic standard | | ADR-RF-004 | RAG pattern for summarization | Accepted | Hallucination reduction, source grounding | | ADR-RF-005 | FAIR compliance scoring | Accepted | Data quality validation | | ADR-RF-006 | CSL for citation formatting | Accepted | 9,000+ styles, industry standard | | ADR-RF-007 | REF-XXX persistent identifiers | Accepted | Unique, portable, human-readable | | ADR-RF-008 | Async provenance logging | Accepted | Non-blocking, performance | ### 5.2 ADR-RF-001: File-Based Storage **Context:** The Research Framework needs to persist search results, metadata, summaries, and provenance logs. Options include SQLite, MongoDB, or file-based JSON/Markdown storage. **Decision:** Use file-based storage with JSON for structured data and Markdown for human-readable documents. **Consequences:** - (+) Simple implementation, no database dependencies - (+) Git-friendly, supports version control - (+) Portable across machines - (+) Human-readable artifacts - (-) No ACID transactions - (-) Performance may degrade with 10,000+ files - (-) No query language (manual file traversal) **Mitigation:** - Implement in-memory indices for frequently queried data - Use directory structure for implicit partitioning - Plan migration to SQLite if scale requires ### 5.3 ADR-RF-002: Agent-Per-Stage Architecture **Context:** The research workflow has distinct stages (discovery, acquisition, documentation, citation). Should these be one monolithic service or separate agents? **Decision:** Implement each stage as a separate agent following AIWG's multi-agent pattern. **Consequences:** - (+) Clear separation of concerns - (+) Agents can evolve independently - (+) Aligns with AIWG's existing agent framework - (+) Enables agent reuse in other contexts - (-) Inter-agent communication overhead - (-) More code to maintain **Mitigation:** - Use Research Orchestrator for coordination - Define clear agent interfaces - Share common services (API client, file I/O) ### 5.4 ADR-RF-003: W3C PROV for Provenance **Context:** Provenance tracking is critical for reproducibility. Options include custom logging, W3C PROV, or Dublin Core metadata. **Decision:** Use W3C PROV-JSON format for all provenance records. **Consequences:** - (+) Industry standard, interoperable - (+) Rich relationship vocabulary (wasGeneratedBy, wasDerivedFrom, etc.) - (+) Enables external tool integration (ProvStore, Neo4j) - (+) Supports academic publication requirements - (-) More complex than simple logging - (-) Requires schema validation **Mitigation:** - Use PROV-JSON (subset of full PROV spec) - Implement validation as non-blocking - Provide simplified query API over raw PROV ### 5.5 ADR-RF-004: RAG Pattern for Summarization **Context:** LLM summarization risks hallucination (inventing facts not in the source). How to ensure accuracy? **Decision:** Use Retrieval-Augmented Generation (RAG) pattern: always include full paper text as context, validate claims against source. **Consequences:** - (+) Reduces hallucination risk significantly - (+) Claims can be traced to source text - (+) Enables automated grounding validation - (-) Higher token costs (full paper as context) - (-) Context length limits (may need chunking) **Mitigation:** - Use efficient chunking for long papers (>15k tokens) - Set low temperature (0.3) for factual accuracy - Implement hallucination detection as post-processing step --- ## 6. Cross-Cutting Concerns ### 6.1 Provenance (W3C PROV) All operations are automatically tracked using the Provenance Agent. **Implementation:** ```typescript // Provenance Agent hooks into all operations class ProvenanceAgent implements ResearchAgent { private logger: PROVLogger; async wrapOperation( operationName: string, agent: ResearchAgent, operation: () => Promise ): Promise { const activityId = this.generateActivityId(operationName); // Log activity start await this.logger.logActivityStart(activityId, operationName, agent.id); try { const result = await operation(); // Log entities created await this.logResultEntities(activityId, result); // Log activity end await this.logger.logActivityEnd(activityId); return result; } catch (error) { await this.logger.logActivityError(activityId, error); throw error; } } async buildLineageGraph(entityId: string): Promise { // Traverse PROV relationships backwards return this.traverseLineage(entityId, 'backward'); } } ``` **Provenance Data Flow:** ``` ┌─────────────────────────────────────────────────────────────────────────────┐ │ Provenance Data Flow │ ├─────────────────────────────────────────────────────────────────────────────┤ │ │ │ Operation Execution │ │ ┌───────────────────────────────────────────────────────────────────────┐ │ │ │ │ │ │ │ [Command] ──▶ [Agent] ──▶ [Operation] ──▶ [Result] │ │ │ │ │ │ │ │ │ │ │ │ └─────────────┴─────────────┴────────────┘ │ │ │ │ │ │ │ │ │ │ intercepts │ │ │ │ ▼ │ │ │ │ ┌─────────────────────┐ │ │ │ │ │ Provenance Agent │ │ │ │ │ │ │ │ │ │ │ │ • Entity capture │ │ │ │ │ │ • Activity logging │ │ │ │ │ │ • Agent attribution│ │ │ │ │ │ • Relationship map │ │ │ │ │ └──────────┬──────────┘ │ │ │ │ │ │ │ │ └─────────────────────────────┼──────────────────────────────────────────┘ │ │ ▼ │ │ Provenance Storage │ │ ┌───────────────────────────────────────────────────────────────────────┐ │ │ │ │ │ │ │ .aiwg/research/provenance/ │ │ │ │ ├── prov-2026-01.json # W3C PROV-JSON log │ │ │ │ ├── lineage-graph.json # Entity relationships │ │ │ │ └── checksums.txt # Integrity verification │ │ │ │ │ │ │ └───────────────────────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────────────────────┘ ``` ### 6.2 Quality Assessment (FAIR and GRADE) **FAIR Compliance Scoring:** | Dimension | Criteria | Max Points | |-----------|----------|------------| | **F (Findable)** | DOI present (40), complete metadata (10 each for title, authors, year, venue, abstract) | 90 | | **A (Accessible)** | Persistent URL (50), clear license (50) | 100 | | **I (Interoperable)** | JSON metadata (50), schema compliance (50) | 100 | | **R (Reusable)** | License permits reuse (50), provenance documented (50) | 100 | **GRADE Quality Scoring:** | Dimension | Criteria | Max Points | |-----------|----------|------------| | **Risk of Bias** | RCT (25), observational (15), anecdotal (5) | 25 | | **Consistency** | Aligns with literature (20), contradicts (10), unknown (0) | 20 | | **Directness** | Directly addresses question (20), indirect (10) | 20 | | **Precision** | Large sample, narrow CI (20), small sample (10) | 20 | | **Publication Bias** | A* venue (15), A (12), B (8), C (5), preprint (3) | 15 | **Overall GRADE Classification:** - High: 80-100 - Moderate: 60-79 - Low: 40-59 - Very Low: <40 ### 6.3 Error Handling ```typescript // Error handling strategy enum ErrorSeverity { CRITICAL = 'critical', // Abort workflow ERROR = 'error', // Abort current operation, continue workflow WARNING = 'warning', // Log and continue INFO = 'info' // Log only } interface ResearchError { code: string; // e.g., 'RF-001' (Research Framework error 001) severity: ErrorSeverity; message: string; operation: string; // Which operation failed recoverable: boolean; // Can user retry?
