# Requirements: v2.0 Three-Lane Real-Topic Natural-Language E2E

## Milestone Goal

Prove that the public AITP front door can steer all three closed research
directions through real natural-language dialogue honestly, without hidden
seed state, while leaving a cross-lane comparative report of what is truly
ready and what still blocks broader deployment.

## Active Requirements

### Lane-Specific Dialogue Proofs

- [x] `REQ-E2E-01`: one real natural-language dialogue run proves the
  formal-theory baseline can be entered through the public front door and stay
  aligned with its bounded positive authoritative-L2 route.

- [x] `REQ-E2E-02`: one real natural-language dialogue run proves the
  toy-model baseline can be entered through the public front door and stay
  aligned with its bounded positive authoritative-L2 route.

- [x] `REQ-E2E-03`: one real natural-language dialogue run proves the
  first-principles / code-method baseline can be entered through the public
  front door and stay aligned with its bounded positive authoritative-L2 route.

### Cross-Lane Comparison

- [x] `REQ-E2E-04`: the milestone closes with a comparative report showing
  where the three dialogue runs succeed honestly, where they still require
  bounded operator intervention, and where hidden-seed assumptions were
  removed or still remain.

- [x] `REQ-E2E-05`: the milestone leaves explicit next routing for any
  remaining blockers discovered during the three dialogue runs, rather than
  leaving them in chat memory.

## Out of Scope

| Feature | Reason |
|---------|--------|
| Reopening bounded positive-L2 closure for any of the three lanes | `v2.0` assumes the baseline closures from `v1.97`–`v1.99` remain the current truth |
| Broad multi-topic benchmark expansion during dialogue testing | keep the milestone tied to one real dialogue proof per lane |
| Production deployment claims | this milestone measures honest E2E readiness, not product launch readiness |

## Traceability
