===== Statement =====

The Phase 0 Implementation Profile / PSM SHALL identify Python as the selected Phase 0 hand-authored implementation language.

===== Source =====

Part 4, Section 21.3: Technology Selection Requirements.

===== Rationale =====

Identifying Python as the selected hand-authored implementation language establishes a consistent development context for Phase 0 source modules, helpers, adapters, processing logic, and other approved hand-authored implementation artefacts.

A defined implementation language also allows the Developer Handbook to establish consistent coding, logging, exception-handling, dependency, and review conventions.

===== Applies To =====

This requirement applies to:

  * Phase 0 hand-authored source code;
  * implementation node modules;
  * supporting modules;
  * wrappers and adapters; and
  * applicable Developer Handbook coding conventions.

===== Verification =====

Verification SHALL confirm that Python is identified as the selected Phase 0 hand-authored implementation language.

Verification activities should include review checks confirming that:

  * governed hand-authored Phase 0 implementation code uses Python where applicable;
  * Python source files follow the Developer Handbook;
  * generated artefacts remain distinguishable from hand-authored Python code; and
  * alternative implementation languages are not introduced into the Phase 0 baseline without approved change control.

===== Traceability =====

This requirement establishes the selected implementation-language context for Phase 0 hand-authored implementation artefacts.
