[v1.3.1] — 2026-03-28

Added

• Cross-Domain Evaluation Suite (eval/, src/post_sim_artifacts.py): introduced 11 new evaluation question types including ZD_RESOLUTION, SF_RISK, and INVOICE_SLA. The framework now includes specialized scorers for financial credits, NPS drivers, and PR review verdicts to validate RAG performance across the entire business logic stack.
• Reactive Customer Reply Loop (src/external_email_ingest.py): implemented a probabilistic customer response system. The simulation now classifies inbound emails (Complaints vs. Feature Requests) and allows customers to autonomously advance Salesforce Opportunity stages based on the quality of outbound sales replies.
• Concurrent Embedding Engine (src/embed_worker.py): replaced the serial background worker with a ThreadPoolExecutor-based system. This supports high-throughput embedding via Infinity (up to 16 concurrent calls) while maintaining causal consistency through a new drain() synchronization mechanism.
• Advanced Retrieval Architectures (eval/eval_e2e.py): added support for Reciprocal Rank Fusion (RRF) and Graph-Augmented Retrievers, allowing the evaluation agent to fuse BM25 lexical search with dense vector embeddings and 2-hop artifact expansion.

Changed

• Stateful Persona Architecture (src/utils/persona_utils.py): refactored persona generation into a centralized PersonaUtils singleton. Voice cards now inject "CRM Pressure" hints, causing internal employees to exhibit higher stress and terser communication when they own at-risk deals or urgent Zendesk tickets.
• CRM-Driven Graph Dynamics (src/graph_dynamics.py, src/flow.py): integrated live Salesforce/Zendesk telemetry into the social graph. Edge weights between liaisons and external contacts now fluctuate based on account sentiment, and stress propagates through the organization when "lighthouse" customers flag risks.
• Theme-Triggered Incidents (src/flow.py): updated the incident generator to be reactive to the daily planning theme. Stability "collisions" are now more likely to fire if the daily plan involves high-risk activities like "migrations" or "refactors" identified via keyword triggers.
• HyDE Query Rewriting (src/memory.py): migrated the recall_with_rewrite logic from a generic callable to a native Bedrock-hosted Llama 3.3 implementation for more robust hypothetical document generation.

Fixed

• PR Review Approval Logic (src/normal_day.py): fixed a bug where engineers would requested changes indefinitely by implementing "Review Round" guidance, forcing approvals after 3 rounds unless critical bugs are present.
• Causal Chain Integrity (src/external_email_ingest.py): corrected an issue where inbound vendor emails were orphaned; all external communications are now properly rooted in a CausalChainHandler and tracked through downstream JIRA/Slack artifacts.
• Cleanup: deleted the legacy src/email_gen.py script in favor of the live, event-driven ingestor system.
