Ingesting the KKS / BCG Singapore Corpus into HRPM-DTH20160 (v2 Annex)

## Scope This release consolidates nine newly received PDFs into case **HRPM-DTH20160 — Danish Thanvi: Decade of State Harassment**: - **KKS_OSINT.pdf** — OSINT profile on Khalid Kareem Siddiqui (kks@backcheckgroup.com) - **BCG Forensic Dossier v2.5** - **BCPL Singapore Strike-off (RAC-665015)** — ACRA correspondence - **Mehvish Travel** email thread (Imran / Khalid / Mehvish / Kazim) - Four KKS operational-failure emails (Bitrix, verification portal, background-check delays, 2020 payment cheque) - Supporting annex material (AM.pdf) ## Chain-of-custody Every file was SHA-256 hashed on ingest and its row in `evidence_uploads` marked `custody_status = HASHED`, with the digest visible in the annex PDF and the evidence register. ## Entity resolution Eight canonical entities were added (Khalid Kareem Siddiqui, Mehvish Ali, Syed Kazim Ali, Shoaib Ahmed Mithani, Shamil Ahmed Khan, Hasan Zafar, Xcluesiv Cloud Technology, Check Expert), with seven name variants attached to the KKS entity to prevent future duplicates. ## Verified relationships Five case-scoped, verified edges were written directly into `entity_relationships` — not inferred: | Source | → | Target | Type | |---|---|---|---| | Khalid K. Siddiqui | → | Background Check Group | employee_of | | Muhammad Imran Haroon | → | Background Check Group | employee_of | | Shoaib Ahmed Mithani | → | Background Check Group | former_employee_of | | Xcluesiv Cloud Technology | → | Background Check Group | infrastructure_provider_of | | Syed Kazim Ali | → | Mehvish Ali | colleague_of | ## Confidence banding Eight of nine items carry a **HIGH** confidence band (direct email headers or ACRA filings). One (AM.pdf) sits at **MEDIUM** pending attribution review. The annex PDF renders the full confidence-band grid, chronology phases, claim matrix, and evidence register in the v2 dossier structure.
