[WIP] Implement compatibility gate operations for evidence cycle

[Copilot]

WS2: Compatibility Gate Operations - Implementation Plan

Objective

Operationalize the compatibility gate validation runbook with repeatable bi-weekly evidence cycles.

Implementation Checklist

• Phase 1: Evidence Collection Infrastructure

  • Create evidence storage directory structure
  • Create helper script for evidence packet generation
  • Add gate review orchestration script

• Phase 2: Workflow Validation Helpers

  • Create workflow validation helper scripts for the 8 baseline workflows
  • Add evidence collection automation per workflow

• Phase 3: Gate Review Reporting

  • Create gate review report generator
  • Add recommendation matrix calculation logic
  • Create sample evidence packets for two workflows (to meet acceptance criteria)

• Phase 4: Documentation and Integration

  • Update MASTER_INDEX.md with new helpers
  • Update active_state.md with completion status
  • Update modernization_execution_tracker.md with progress

Scope

• Focus on minimal infrastructure to enable bi-weekly gate cycles
• Provide tooling to produce evidence packets with consistent format
• Enable gate recommendation publishing (proceed/proceed-with-conditions/hold)
• Generate at least two complete evidence packets to meet acceptance criteria

<issue_title>WS2: Compatibility Gate Operations (bi-weekly 8-workflow evidence cycle)</issue_title>
<issue_description>## Context
Operationalization of docs/plans/modernization_compatibility_gate_validation_runbook.md.

Objective

Run a repeatable compatibility evidence cycle as a release gate for modernization work.

Scope

• Execute 8 baseline workflows on bi-weekly cadence
• Produce evidence packets (artifacts, rollback status, pass/fail)
• Publish gate recommendation: proceed / proceed-with-conditions / hold

Acceptance Criteria

• At least two complete gate cycles executed with consistent packet format
• Phase reviews reference runbook evidence directly
• Regression ownership and rollback readiness are tracked per cycle
