Summary

  • audit the formalization paper against the merged Lean stack with parallel read-only passes over theorem surface, narrative/proof structure, and paper artifacts
  • clarify that embeddings and other representations can themselves be treated as relative observation quotients, so the finite target fixes where the quotient chain stops
  • update the paper for reachable-image rule counts, product/query-document theorem anchors, comparison/ranking support names, product-domain caveats, window/profile/margin caveats, and a broader three-part conclusion
  • mirror key top-k/tie, product-domain, and near-margin caveats in the RAG guide and reviewer brief
  • add checked paper-referenced names to docs/theorem-map.md and regenerate the paper PDF/text artifact

Audit Notes

Subagent audit found no stale Lean theorem names and no major overclaims. The main gaps were under-cited product/comparison theorem names, a conclusion that lagged the product/window/profile layers, and caveats around full-product-domain image equalities, top-k/tie behavior, finite-window scope, and near-threshold margins.

File Changes

1. docs/paper/ordvec_formalization_paper.tex 📝 Documentation +85/-10

Expand paper scope with relative observations and retrieval layers

• Add new section clarifying that observation spaces are relative and embeddings can be treated as
 quotient maps with finite recursion stopping at the target
• Insert reachable-image cardinality theorem card_quotientImageRules with formula `|A^{im(Q)}| =
 |A|^{|im(Q)|}`
• Rename subsection from "Refinement and products" to "Refinement and paired targets over one
 quotient" and clarify distinction from product-map quotient
• Add product-domain caveats explaining that product-image equalities apply to full formal domain,
 not arbitrary logged graphs or prefiltered traces
• Expand conclusion from two to three complementary messages, adding retrieval-facing composition
 layers (product quotients, comparison quotients, observation windows, margin/profile theorems)
• Add four new non-claims about top-k equality, product-image domain restrictions, near-threshold
 decisions, and continuous embedding theorems
• Add checked Lean theorem names for product and comparison quotient operations

2. docs/paper/ordvec_formalization_paper.txt 📝 Documentation +88/-36

Regenerate text artifact from updated paper

• Regenerate text artifact from updated LaTeX source
• Add clarification on relative observation spaces and finite recursion stopping at target
• Include reachable-image cardinality theorem and product-domain caveats
• Update conclusion to three-part structure with retrieval-facing composition

3. docs/rag-pipeline-guide.md 📝 Documentation +12/-2

Mirror key caveats and expand scope in RAG guide

• Expand opening section to mention broader quotient stack beyond bitmap theorem (product
 query/document behavior, multi-target signatures, lossy probes, score-threshold decisions)
• Add caveats about pairwise ranking-comparison preservation not proving top-k equality, tie-policy,
 or nDCG preservation
• Add caveat about near-threshold score decisions requiring explicit margin evidence
• Add section clarifying that product-image equalities apply to full formal domain, not prefiltered
 traces or logged candidate graphs

4. docs/reviewer-brief.md 📝 Documentation +16/-0

Add full quotient stack section and mirror domain caveats

• Add new "Full Quotient Stack" section describing broader formalization beyond bitmap theorem
 (quotient search, reachable-image/kernel, fiber topology, product quotients, ranking comparisons,
 observation windows, margin/profile certificates)
• Add caveats about pairwise retrieval and ranking decisions requiring empirical support
• Add caveat that ranking-comparison preservation alone is not top-k, tie-policy, or nDCG theorem
• Add caveat that product-image equalities are theorems about full formal domain, not prefiltered
 traces
• Add caveat about near-threshold score decisions requiring explicit margin evidence

5. docs/theorem-map.md 📝 Documentation +14/-0

Add checked paper-referenced Lean theorem names

• Add foundational quotient theorems and FNCH-specific threshold optimality theorems to theorem map

Code Review

This pull request updates the documentation and formalization papers to detail the broader Lean quotient stack, clarifying aspects such as product quotients, ranking comparisons, observation windows, and score-threshold decisions. It also explicitly documents non-claims, such as the fact that ranking-comparison preservation alone does not guarantee top-k list equality or nDCG preservation. The review feedback suggests minor wording improvements in the documentation to ensure semantic precision, specifically replacing category-mismatched terms like 'proves' or 'is not a theorem' with 'guarantees' or 'does not guarantee' when describing properties.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
