Go Review Lenses

Three adversarial Go code-review prompts ("lenses") for an independent reviewer in a @swamp/software-factory run. The Go analogue of @atalanta/ts-review-lenses — same three-pass structure, same swamp/findings contract, same IDIOM-/CORR-/ARCH- id prefixes, written for Go specifically rather than adapted from the TypeScript prose.

• Lens A (idiom) — idiomatic, with-the-grain Go: small interfaces defined at the point of use, errors as values, functional options, enums via iota, no transliteration from another language.
• Lens B (correctness vs reality) — boundary validation, the nil-interface trap, goroutine/slice-aliasing correctness, determinism, resource cleanup, grounded tests.
• Lens C (architecture) — package boundaries, the purity seam, dependency direction, change confinement, no speculative generality. Cites Ben Johnson's "Standard Package Layout" and Peter Bourgon's "Go best practices, six years in" directly.

Run as three separate passes (IDIOM-/CORR-/ARCH- finding id prefixes keep them distinct). The lens files are transport-neutral review prose; the swamp + findings-JSON contract is appended at run time.
