# v1.92 Milestone Audit

Status: passed

## Scope Closed

- Phase `166`: Public Front Door L0 Source Handoff
- Phase `166.1`: Contentful Source Registration Default

## Requirements Coverage

Score: `4/4` requirements satisfied

- `REQ-L0HAND-01` satisfied by the concrete public-front-door `L0` handoff
- `REQ-L0HAND-02` satisfied by shared dashboard / runtime protocol / replay
  parity
- `REQ-L0HAND-03` satisfied by contentful-by-default arXiv registration plus
  discovery parity
- `REQ-VERIFY-01` satisfied by the fresh-topic real-kernel proof lane

## Verification Evidence

- `157 passed` on the Phase `166` targeted parity sweep
- `223 passed` on the Phase `166` full parity sweep
- `11 passed` on the schema-contract slice
- `105 passed` on the Phase `166.1` targeted regression slice
- one isolated temp-kernel first-run proof
- one real repository-kernel proof under
  `.planning/phases/166.1-contentful-source-registration-default/evidence/jones-chapter-4-source-registration-proof-20260413/`

## Accepted Open Gaps

- broader provider expansion beyond arXiv-first surfaces
- automatic source acquisition from the runtime queue
- remaining non-milestone backlog items in `.planning/BACKLOG.md`
