# Phase 107: Public Doc Boundary Guard - Context

**Gathered:** 2026-04-11
**Status:** Implemented and verified
**Mode:** Second implementation phase for `v1.58`

<domain>
## Phase Boundary

Continue `v1.58` by locking the public roadmap boundary in the documentation
test suite.

</domain>

## Implementation Decisions

### Locked decisions

- reuse the existing documentation-entrypoint test file instead of creating a
  one-off roadmap-only harness
- keep the check narrow: assert public-facing language and assert the absence of
  direct `.planning/` links

</decisions>
