# Requirements: v1.91 Real Topic L0 To L2 End-To-End Validation

## Milestone Goal

Close the next post-`v1.90` maturity gap so AITP can prove whether the current
protocol and implementation are genuinely useful on a real topic from an
initial idea through one honest bounded research outcome.

## Archived Requirements

### Real Topic E2E Surface

- [x] `REQ-E2E-01`: at least one real topic runs through the current public
  AITP entry surfaces from an initial idea rather than from a synthetic seeded
  fixture.
- [x] `REQ-E2E-02`: the real-topic run leaves one durable postmortem naming
  the actual route, artifact refs, friction points, and bounded outcome.

### GSD Linkage Rule

- [x] `REQ-E2E-03`: every discovered issue is recorded in one durable issue
  ledger and is not left only in runtime artifacts or chat memory.
- [x] `REQ-E2E-04`: every issue from the ledger is routed into explicit
  GSD-tracked follow-up work (decimal phase, next milestone candidate, or
  backlog item) instead of assuming GSD will auto-discover it.

## Traceability

| Requirement | Phase | Final Status |
|-------------|-------|--------------|
| REQ-E2E-01 | Phase 165.6 | Satisfied |
| REQ-E2E-02 | Phase 165 | Satisfied |
| REQ-E2E-03 | Phase 165 | Satisfied |
| REQ-E2E-04 | Phase 165, 165.1, 165.2, 165.3, 165.4, 165.5, 165.6 | Satisfied |

## Outcome Notes

- `REQ-E2E-01` was not satisfied by the first Jones route because that run
  resumed an existing shell; it was closed later by the fresh public-front-door
  run in `165.6`
- `REQ-E2E-02` and `REQ-E2E-03` were satisfied by the original Jones
  postmortem + issue-ledger slice in Phase `165`
- `REQ-E2E-04` became satisfied across the milestone chain because the issue
  ledger's routed work actually landed in later phases and backlog follow-up
