FIELDCRAFT #005 — THE SOURCE CHAIN
One Verified Fact Opens the Next Database. One Name Leads to the Next Name. The Chain Is the Investigation.
SUBJECT: OSINT SOURCE-CHAINING METHODOLOGY // CROSS-DATABASE MOVEMENT, INVESTIGATIVE THREADING, ABSENCE ANALYSIS, INSTITUTIONAL NETWORK MAPPING
DATE: APRIL 18, 2026
CROSS-REF: FIELDCRAFT SERIES | THE OPERATOR | THE PUBLICATION GAP | THE LONG COUNT
DATA CONFIDENCE: VERIFIED (all methods are demonstrated in published Sentinel briefings, all tools referenced are publicly accessible)
We are building the video side of this operation. If you want the briefings in a format you can watch, subscribe to The Sentinel Network on YouTube.
This is the fifth installment of FIELDCRAFT. The briefings give you the intelligence. FIELDCRAFT gives you the tradecraft.
Why Source-Chaining
You now have four tools.
FIELDCRAFT #001 gave you the AI research prompt that overrides consensus bias. FIELDCRAFT #002 gave you patent databases. FIELDCRAFT #003 gave you public records. FIELDCRAFT #004 gave you scientific preprints.
Each tool answers a different question. Patents tell you what someone built. Public records tell you who they are. Preprints tell you what they found. The AI prompt helps you read all three without institutional distortion.
This installment teaches you the skill that connects them. Source-chaining is how one verified fact opens the next database, how one name leads to the next name, and how a single data point in one system becomes a search query in the next. The chain is the investigation. Everything we have published was built this way.
