Add test compliance audit template (spec+validation → test code)

[Alan-Jowett]

Summary

Add an \�udit-test-compliance\ template that audits test code against requirements and validation plan. Answers: do the tests verify what the plan says they should?

Context

PR #35 shipped the \�udit-traceability\ template for cross-document specification drift (D1–D7). The \specification-drift\ taxonomy reserves D11–D13 for test compliance drift types. This is Phase 2 of the specification integrity roadmap.

Scope

New components needed:

• Template: \�udit-test-compliance\ — consumes requirements-document + validation-plan + test code; produces investigation-report
• Protocol: \ est-compliance-audit\ (reasoning) — phased methodology for mapping validation plan test cases to actual test implementations
• Taxonomy extension: Define D11–D13 labels in \specification-drift\ taxonomy (e.g., D11_UNIMPLEMENTED_TEST_CASE, D12_UNTESTED_ACCEPTANCE_CRITERION, D13_ASSERTION_MISMATCH)

Reused components:

• \specification-analyst\ persona
• \investigation-report\ format
• \�nti-hallucination\ + \self-verification\ guardrails

Drift types to define

Label	Description
D11	Test case in validation plan has no corresponding automated test
D12	Acceptance criterion has no assertion in the test implementation
D13	Test assertions don't match the expected behavior from the plan

Acceptance criteria

• Template, protocol, and taxonomy extension created
• Manifest updated
• \ ests/validate-manifest.py\ passes
• Case study or scenario added to docs
