# Requirements: v1.36 L0 L1 Source Intelligence And Physicist-Grade Intake

## Shipped Requirements

- ✓ `REQ-SRC-01`: AITP now assigns more durable source identity so the same
  paper or note can be recognized across related topics.
- ✓ `REQ-SRC-02`: AITP now surfaces citation-graph and source-neighbor signals
  more explicitly than the earlier minimal baseline.
- ✓ `REQ-L1-01`: `L1` intake now carries stronger source-backed assumption,
  regime, and reading-depth structure.
- ✓ `REQ-L1-02`: `L1` intake now surfaces contradiction candidates and
  notation-alignment tension instead of remaining shallow extraction only.
- ✓ `REQ-L1-03`: The stronger `L0/L1` intelligence now appears in runtime/topic
  read paths so later layers can actually consume it.

## Final Traceability

## Outcome Notes

- No milestone requirements were dropped.
- No milestone requirements remain unchecked.
- Runtime read-path exposure was validated with both the integrated slice and
  the full `research/knowledge-hub` pytest suite.
