# Requirements: v1.46 Global Source Catalog And Citation Reuse Maturity

## Shipped Requirements

- ✓ `REQ-SCAT-01`: AITP now compiles a global deduplicated source catalog
  across topic-local `source_index.jsonl` artifacts.
- ✓ `REQ-SCAT-02`: Operators and runtime code can inspect cross-topic source
  reuse and catalog-linked references through production service/CLI surfaces.
- ✓ `REQ-SCAT-03`: Cataloged source identity now supports bounded
  citation-traversal and source-family reuse surfaces instead of static counts
  only.
- ✓ `REQ-SCAT-04`: Source fidelity is now explicit and consumable by
  runtime/read surfaces.
- ✓ `REQ-VERIFY-01`: The milestone closes with a non-mocked verification path
  proving the matured source catalog and citation-reuse surface through
  production code.

## Final Traceability

| Requirement | Assigned Phase | Final Status | Evidence |
| --- | --- | --- | --- |
| `REQ-SCAT-01` | `66` | validated | `compile-source-catalog` plus `source_catalog.json|md` |
| `REQ-SCAT-02` | `66` | validated | service/CLI source catalog entrypoint and cross-topic reuse summary |
| `REQ-SCAT-03` | `67` | validated | `trace-source-citations`, `compile-source-family`, and bounded traversal/family artifacts |
| `REQ-SCAT-04` | `68` | validated | `fidelity_rows`, `fidelity_summary`, runtime-note rendering, and schema updates |
| `REQ-VERIFY-01` | `69` | validated | `run_source_catalog_acceptance.py --json` plus full-suite regression |
