Move KOSIS general lookups and Kakao Local geocoding behind k-skill-proxy so users do not need to manage those API keys for common skill flows. Keep KOSIS bigdata/direct calls user-keyed because userStatsId is account-specific.
Constraint: Free API proxy policy allows proxying upstreams that require API keys while keeping routes narrow, cache-backed, and public.
Rejected: Proxy ODsay transit routing | Basic quota is low, time-limited, and IP-whitelist-bound, so centralizing it would create quota and operations risk.
Confidence: high
Scope-risk: moderate
Directive: Keep KOSIS bigdata direct unless a per-user credential design is added; do not route broad Kakao surfaces without explicit allowlists and rate limits.
Tested: npm run ci; local KOSIS proxy smoke via /v1/kosis/search and /v1/kosis/meta; local Kakao proxy smoke via /v1/kakao-local/geocode q=서울역.
Not-tested: Production proxy deployment after main merge/cron update.
