Choose systems languages and idioms

Route systems-language work by language axis to idiomatic patterns and testing

When setting up Go, C++, or Perl projects that need shared conventions, test-first discipline, and language-appropriate safety.

• · language choice (Go/C++/Perl)
• · task type (write/test/harden)

• · language-specific conventions
• · test framework + toolchain
• · error model rules

Language identified; TDD discipline

• · Mixed idioms across languages
• · unsafe Perl input handling
• · skipped tests

• · per-language idiom/error/tooling matrix
• · shared TDD guardrails
• · Perl taint mode enforcement
