====== 18.9 Developer Handbook Traceability ======

[[fxdemo:04-part:18-phase-0-implementation-traceability-model:start | Go To Phase 0 Implementation Traceability Model ]]

Developer Handbook [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|traceability]] relates handbook rules to the Phase 0 implementation concerns they govern.

A Developer Handbook trace must identify:

  - Handbook rule or section
  - Implementation concern governed by the rule
  - Artifact categories affected
  - Part 4 requirement or convention supported
  - Review checklist item associated with the rule
  - Affected repository locations where applicable
  - Affected file-header, generated-file, logging, exception-handling, naming, traceability, or workflow convention
  - Approval or review status of the rule

Developer Handbook traceability ensures that handbook rules support the Phase 0 Implementation Profile rather than becoming disconnected developer preferences.

The Developer Handbook remains subordinate to Part 4. It provides practical development rules for contributors; it does not redefine the implementation profile or the architecture.
