Development Harness Documentation

<shared_reference_routing> Load the smallest reference matching the task. This skill routes shared documentation; it does not own or run the development-harness lifecycle.

• Artifact Conventions — artifact naming, logical storage, and cross-reference tokens.
• Default Development Flow — S1–S7 sequencing, stage handoffs, and ARL gates.
• dh:dh-cli-usage — resolve the DH CLI and read its grouped-command reference.
• Human Touchpoint Model — whether a constraint requires human escalation.
• Impact Analysis Principles, at Impact Analysis Principles — cross-domain concepts, examples, and the full change lifecycle.
• Impact Analysis Gap Supplement, at Impact Analysis Gap Supplement — impact-set calibration, implicit contracts, external triggers, control removal, delayed effects, paired measurement, and unsafe interactions.
• Change-Impact Analysis Research, at Change-Impact Analysis Research — primary-source evidence for the method.
• Role Resolution Protocol — resolve abstract harness roles to language-plugin agents.
• SDLC Stage Taxonomy — choose canonical stage names.
• Severity Workflow-Continuity Lens, at Severity Workflow-Continuity Lens — worked examples of the continuity lens for defect classification and impact analysis.
• Backlog Item Groomed Schema, at Backlog Item Groomed Schema — content rules and required Groomed-section structure for backlog-item-groomer output. </shared_reference_routing>
