Narrow the Naver Maps proxy contract to JSON reverse geocode responses and preserve upstream quota signals so client fallback can make accurate decisions.
Constraint: PR #282 review requested TDD fixes for XML contract mismatch, upstream 429 mapping, lint coverage, and route option documentation.
Rejected: XML passthrough in this follow-up | It would require a separate response-shaping contract and tests beyond the JSON proxy boundary.
Confidence: high
Scope-risk: narrow
Directive: Keep Naver Maps auth failures sanitized as 503 without upstream body snippets while preserving non-auth diagnostic snippets.
Tested: node --test packages/k-skill-proxy/test/server.test.js; node --test scripts/skill-docs.test.js; bash scripts/validate-skills.sh; PYENV_VERSION=3.12.0 npm run ci; architect verification CLEAR
Not-tested: Live NCP Maps calls with production credentials
