KR Prototyping Documentation - Action Plan

Status: ⚠️ Documentation refinement required before coding can begin
Summary: While high-level strategy and repository format are well-defined, critical gaps exist in the ProofPower HOL interface specification that would block implementation.

Critical Issues Requiring Resolution

1. Extension Grouping Algorithm - UNRESOLVED

Problem: No clear algorithm for grouping ProofPower constants with their defining constraints into SPaDE extensions.

Current State:

“The best way to do this is not yet clear. The two possibilities which come to mind are: [incomplete]”

Required Action:

• Choose between tag-based vs. constraint-analysis approaches
• Provide complete algorithmic specification with pseudocode
• Include handling of edge cases (mutual recursion, orphaned constants)

2. Structure Building Process - UNDERSPECIFIED

Problem: Vague description of “stack of positions” mechanism for building repository structure.

Required Action:

• Define precise stack-based construction algorithm
• Specify position tracking and referencing mechanism
• Provide step-by-step procedure for theory construction

3. Main Procedure Interface - MISSING

Problem: No specification of entry point, parameters, or calling convention.

Required Action:

• Define main SML procedure signature
• Specify input/output parameters and configuration options
• Document error codes and return values

Documentation Files Requiring Updates

Immediate Priority

• kr/ppholinterface.md - Complete sections 2.2, 2.3, add error handling
• kr/SPaDEppScrape.md - Expand from stub to full specification
• kr/m4002.md - Add main procedure and integration details

Supporting Updates

• kr/README.md - Update links to reflect new detailed specifications
• kr/KRproto.md - Cross-reference completed interface specification

Quality Assurance

Before Implementation

• All Priority 1 issues resolved in documentation
• Sample walkthrough of complete scraping process documented
• Error handling strategies defined for all failure modes
• Testing approach specified

Implementation Readiness Criteria

• Main procedure interface fully specified
• Extension grouping algorithm implemented and tested
• Structure building process validated with examples
• Integration with existing Python serialization verified

Estimated Timeline

• Documentation Refinement: 2-3 days (assuming domain expertise available)
• Review and Validation: 1 day
• Implementation Ready: After documentation updates complete

Next Steps

1. Address Priority 1 documentation gaps
2. Create detailed walkthrough examples
3. Validate specifications with domain expert review
4. Proceed to implementation phase

This action plan should be updated as documentation refinements are completed.
