po v3.17.0 — Real-World Applicability IV (Scalar-VO Test Codegen Correctness & Geography Auto-Wrap) Track A: fixes non-compiling generated filter tests for primitive-backed scalar value-objects (buildScalarArgLiteral / buildInArgLiteral / emitter zeroValueLiteral; full numeric family incl. complex/uintptr). Track B: typemap-gated, default-on geography auto-wrap (ST_AsGeoJSON / ST_GeogFromText) with column-level precedence and a po:read=raw opt-out. Proven on the example (live-PG round-trip) and on the real well-be project (compiles as-is, go vet clean, geo auto-wrapped). 9/9 requirements; example byte-equal except two sanctioned additive fixtures; 0 net-new deps; ratchet held; golangci 0; vuln clean.
