# v1.91 Milestone Audit

Status: passed

## Scope Closed

- Phase `165`: Real Topic L0 To L2 End-To-End Validation
- Phase `165.1`: Proof Engineering Knowledge Layer — Schema + Bootstrap
- Phase `165.2`: Mode Envelope Runtime Enforcement + Literature Intake Fast Path
- Phase `165.3`: HCI Foundation — Human-Readable Surfaces + Onboarding
- Phase `165.4`: Agent Governance — Mechanical Verification + Schema Isolation
- Phase `165.5`: L0/L1 Integration — DeepXiv Progressive Reading + Graphify Concept Graph
- Phase `165.6`: Milestone Closure Gap — Public Front Door Real-Topic Proof

## Requirements Coverage

Score: `4/4` requirements satisfied

- `REQ-E2E-01` satisfied by the fresh public-front-door Jones closure lane
- `REQ-E2E-02` satisfied by the durable postmortem bundle
- `REQ-E2E-03` satisfied by explicit issue ledgers
- `REQ-E2E-04` satisfied by routed follow-up work across `165.1` to `165.6`
  plus backlog item `999.86`

## Verification Evidence

- `python -m pytest research/knowledge-hub/tests/test_proof_engineering_bootstrap.py -q`
  - result: `3 passed`
- `python research/knowledge-hub/runtime/scripts/run_first_run_topic_acceptance.py --json`
  - result: `success`
- `python -m pytest research/knowledge-hub/tests -q`
  - result: `579 passed, 22 subtests passed`

## Accepted Open Gaps

- `999.52` broader proof-engineering memory distillation beyond the first Jones
  seed
- `999.86` more concrete `L0` source-acquisition handoff after public bootstrap
