+# Development Log: No Evidence, No Project Claim
+
+## Purpose
+Prevent hallucinated project implementation claims when Second Brain provides only general architecture notes.
+
+## Problem
+The assistant could read general notes such as `API Gateway.md` and then describe API Gateway as if it were implemented in the current project. General concept references are useful, but they are not evidence of the current project state.
+
+## Implementation Summary
+- Added source type classification for Second Brain Trace documents:
+  - Project Evidence
+  - User Decision
+  - General Knowledge
+  - Reference Only
+- Added `canSupportProjectClaim` and `warning` fields to trace documents.
+- Updated trace context to include No Evidence, No Project Claim rules.
+- Added grounding guidance based on project evidence and grounding score.
+- Updated base system prompt to separate confirmed facts, inferences, general knowledge, and verification needs.
+- Updated Chronicle Guard prompt with the same evidence policy.
+- Added tests for General Knowledge notes such as API Gateway.
+
+## Changed Files
+- `src/features/secondBrainTrace.ts`
+- `src/utils.ts`
+- `src/features/projectChronicle/guardPrompt.ts`
+- `tests/secondBrainTrace.test.ts`
+- `tests/projectChronicleGuardPrompt.test.ts`
+
+## Verification
+- `./node_modules/.bin/tsc --noEmit`
+- `npm run compile`
+- `./node_modules/.bin/jest --runInBand`
+
+## Result
+The assistant should now treat general architecture notes as concepts only, not as proof that the current project implements those concepts.
