Scope

Content Accuracy (26 issues across 6 files)

Documentation claims that do not match current implementation:

• docs/architecture/workflows.md — Workflow inventory missing 9 of 30 workflows; PR Validation states "12 parallel jobs" but actual count is 16; Mermaid diagrams incomplete; npm scripts table documents 11 of 24 entries; Extension Publishing diagram shows phantom nodes
• docs/architecture/testing.md — Coverage threshold documented as 70% but pester.config.ps1 sets 80%; coverage directories lists 4 but actual is 7; directory tree missing plugins/, collections/ test directories
• .github/copilot-instructions.md — Scripts Organization missing scripts/plugins/; lint:all chain description missing lint:marketplace; npm script list missing lint:marketplace and spell-check
• CONTRIBUTING.md — Validation Commands section missing 5 scripts (lint:links, lint:collections-metadata, lint:marketplace, lint:version-consistency, validate:copyright)
• .devcontainer/README.md — Lists Mermaid CLI and Checkov as installed but neither is present; missing actionlint and PowerShell modules; Node.js listed as "LTS" but pinned to 20
• scripts/README.md — Linting and Security tables use generic names instead of actual script filenames; missing Plugins and Collections sections
