[WIP] Audit repository documentation against 2024-2026 standards

[Copilot]

Documentation Audit & Remediation Plan

Phase 1: Repository Exploration & Analysis

• Explore repository structure and existing documentation
• Identify existing documentation files (70+ markdown files found)
• Review key documentation (README, PRD, TESTING, API guides)
• Analyze codebase structure (825 source files, 87 pages, 61 backend functions)
• Assess current documentation state

Phase 2: Documentation Audit Report Creation

• Create comprehensive DOCUMENTATION_AUDIT.md report with:
  • Executive Audit Summary
  • Documentation Inventory
  • Missing & Incomplete Documentation (with placeholders)
  • Recommended Documentation Structure
  • Feature-by-Feature Documentation Review
  • Edge Cases & Undocumented Risks
  • Immediate Remediation Priorities

Phase 3: Create Missing Documentation Placeholders

• Create placeholder files for missing/incomplete documentation
• Organize documentation in recommended structure
• Update README and DOCUMENTATION_SUMMARY.md references

Phase 4: Validation & Finalization

• Review audit report for accuracy
• Ensure all placeholders follow naming convention
• Final commit and report

Original prompt

SYSTEM ROLE
You are a principal-level software architect, staff engineer, and documentation standards reviewer.
You audit documentation with the rigor of a senior engineering review, not a tutorial writer.
You do not assume completeness. You do not invent missing material.

OBJECTIVE
Audit this repository (code + docs) against current (2024–2026) best-practice documentation standards.
Identify what exists, what is incomplete, what is missing, and what must be added to reach production-grade quality.

You must:

1. Audit and grade existing documentation
2. Flag missing or incomplete documentation explicitly
3. Create named placeholders for missing documents (do NOT fabricate content)
4. Propose a complete, modern documentation structure
5. Surface edge cases, risks, and undocumented assumptions

SCOPE OF DOCUMENTATION TO AUDIT AND/OR CREATE
Audit and update or scaffold the following documentation domains:

• API Documentation
• Architecture Documentation
• Repository Structure & Conventions
• Test Strategy & Test Suites Documentation
• Feature Documentation (each feature reviewed like a senior-graded paper)
• Edge Cases & Failure Modes
• Changelog / Release Notes
• Environment & Configuration
• Security & Access Controls
• Deployment & CI/CD
• Observability & Monitoring
• Governance / Ownership (if applicable)

AUDIT RULES (NON-NEGOTIABLE)

• Do NOT assume missing docs exist.

• Do NOT silently fix gaps.

• Every missing or incomplete document must be explicitly listed.

• Every placeholder must follow this exact naming format:

  [Missing Document Name - STATUS]

Where STATUS is one of:

• Not Started
• Incomplete
• Outdated
• Needs Review

EXAMPLES:

• [API_ERROR_HANDLING.md - Not Started]
• [ARCHITECTURE_DECISIONS.md - Incomplete]
• [SECURITY_MODEL.md - Outdated]

FEATURE REVIEW STANDARD
For EACH major feature:

• Describe its purpose
• Identify expected inputs/outputs
• Identify dependencies
• Identify failure modes and edge cases
• Grade documentation quality using a senior review lens:
  (Excellent / Adequate / Weak / Missing)
• Flag undocumented behavior explicitly

DOCUMENT QUALITY CRITERIA
Judge documentation using these criteria:

• Accuracy
• Completeness
• Traceability to code
• Change resilience
• Operational usefulness
• Onboarding clarity
• Senior-engineer readability

OUTPUT FORMAT (STRICT)
Return results in the following sections ONLY:

1. Executive Audit Summary

   • Overall documentation maturity
   • Highest-risk gaps
   • Systemic issues

2. Documentation Inventory

   • Table or structured list of all existing documents
   • Status: Complete / Incomplete / Outdated

3. Missing & Incomplete Documentation

   • Explicit list using the placeholder naming format

4. Recommended Documentation Structure

   • Proposed /docs folder tree
   • Clear intent for each document

5. Feature-by-Feature Documentation Review

   • One subsection per feature
   • Include grading and missing elements

6. Edge Cases & Undocumented Risks

   • List assumptions, silent failures, and dangerous gaps

7. Immediate Remediation Priorities

   • What must be written first to reach production readiness

CONSTRAINTS

• Do not write full documentation unless explicitly asked later.
• Do not invent features.
• Do not soften critique.
• Assume this will be read by senior engineers and auditors.

BEGIN THE AUDIT USING THE PROVIDED REPOSITORY CONTENT.

Summary by cubic

Sets up a repo-wide documentation audit aligned with 2024–2026 standards and scaffolds a modern docs structure to identify and close gaps.

• New Features
  • Added audit plan and grading rubric for code and docs.
  • Created placeholder documents using the “[Document Name - STATUS]” format to flag missing/incomplete items.
  • Proposed /docs folder tree for API, architecture, security, CI/CD, and operations, plus immediate remediation priorities.

^{Written for commit f67bacd. Summary will update on new commits.}
