📌 Key Takeaways

• Divide & Conquer Full Suite: Filtering 85% routine consumables across 4 million public contracts, we expanded our targeted surveillance pipeline to encompass 6 high-risk sectors (Sectors 1–6) covering structural public corruption corridors.
• Unmasking 2 Elusive Blind Spots:
  1. Sector 5 ($40K Preferential Smurfing): Exploiting statutory affirmative action ceilings ($40,000 / 50M KRW) by clustering split contracts at $39,000 (99.0% threshold proximity), catching $180,000 in evasive awards.
  2. Sector 6 (December Fiscal Dumping): Rushing $120,000 across 3 consecutive sole-source awards within 4 days in late December to avoid budgetary clawbacks.
• 2 Preempted Architectural Hurdles:
  1. Built a Sweet Spot (96–99.8%) Proximity Engine distinguishing genuine social enterprise support from artificial splitting.
  2. Designed Temporal Density & Task Feasibility Analyzers distinguishing standard year-end settlements from rushed dumping where completion is physically impossible.
• 3 Real Production Bugs Resolved: Multi-sector classification collisions resolved via priority weighting, VAT gross/net confusion fixed by reverse-calculating supply costs, and fiscal year carry-over date shifts resolved.

📌 Key Takeaways

• Eliminating Alert Fatigue: In massive public procurement feeds where 80–95% of transactions represent routine office consumables, our 3-Dimensional Sector Partition Manager filters out 85%+ noise, focusing deep AI reasoning onto high-risk sectors.
• Anticipated Challenges & Prevention: To handle public API latency and schema deprecations, we decoupled the ingestion tier with an isolated SQLite unaudited buffer queue and exponential backoff retry policies.
• 3 Real-World Production Bugs Resolved:
  1. Caret (^) Multi-Value Delimiters: Legacy API fields returning composite records flattened via regex parsers and strict type schemas.
  2. Browser UI Freezes in Vis.js: Visualizing thousands of knowledge graph nodes caused severe UI lockups, solved by Depth-1 Ego-Network subgraph virtualization, cutting latency by 98%.
  3. Duplicate Contract Alerts: Polling shifts triggered redundant findings, eliminated using SHA-256 fingerprint hashes guaranteeing pipeline idempotency.
• Shipped Artifact: Launched Inspector Web Portal v2.0 with live API sync, a 10-year precedent database, instant HWPX parsing, and 13/13 integration tests passed.
