  - TC-002 → Core Principle (self-hostability)

- ADR-008: Fixed invalid NFR-501 reference
  - Added TC-006 (pgvector extension)

- ADR-011: Fixed invalid FR-201-205 and NFR-201 references

- ADR-012: Fixed invalid FR-401, FR-402, NFR-302 references
  - Now references new FR-800 series (Cost & Budget Management)

## ADR-007 Model Identifier Fix

## New Requirements Added
