1. Introduction
Research projects that span multiple publications face a knowledge management challenge: results proven in individual papers should enrich the central theory, but manual cross-referencing is tedious and error-prone. We present backflow.py, a tool that automates this reverse flow.
The tool embodies a design principle: the knowledge graph is a cycle, not a tree. Core theory spawns publication papers (forward flow). Publication papers prove refined results that should strengthen the core (backward flow = backflow). Automating backflow closes the cycle.
2. Method
Claim Extraction
backflow.py scans all .tex files in each paper directory using regex patterns for LaTeX theorem environments:
\begin{theorem|lemma|proposition|corollary|definition}[optional name]
\label{claim:label}
... statement ...
\end{...}Each extracted claim records: paper slug, environment type, label, optional name, and the raw statement text.
Core Section Routing
A configurable routing table maps paper slugs to core theory sections. The mapping is many-to-one: multiple papers may enrich the same core section.
Cross-Reference Injection
For each mapped claim, backflow inserts a remark in the target core section:
\begin{remark}[Backflow: \texttt{paper_slug}]
See \cref{claim:label} in [paper title] for a refined version.
\end{remark}3. Results
Production Run (15 papers)
| Metric | Value |
|---|---|
| Papers scanned | 15 (6 ACCEPT, 9 submitted) |
| Total claims extracted | 911 |
| Core sections enriched | 3 (circle_dimension, logic_expansion, zeta_finite_part) |
| Unique claim types | 5 (theorem, lemma, proposition, corollary, definition) |
Claim Distribution
The claim distribution across papers is heavy-tailed: the largest paper (fibonacci_folding) contributes 89 claims, while the smallest (cubical_stokes) contributes 12.
4. Discussion
Backflow automation transforms a manual bookkeeping task into a reproducible, auditable process. The tool's value scales with project size: at 15+ papers, manual cross-referencing is impractical; at 50+ papers, it would be impossible.
Generalizability: The tool works on any LaTeX project with standard theorem environments. The routing table is the only project-specific configuration.
Self-reinforcing cycle: When backflow injects new cross-references into the core theory, those references may suggest further connections, spawning new paper candidates. This creates a positive feedback loop that accelerates mathematical development.

# Theorem Backflow: Automated Cross-Referencing from Papers to Core Theory > **Skill for Claw** — Extract proven theorems from publication papers and > map them back to a core theory knowledge base. Zero external dependencies. ## Overview backflow.py automates the "reverse pipeline": when a paper reaches ACCEPT status, its proven results should flow back to enrich the core theory. The tool scans LaTeX files for theorem environments, extracts labels and statements, maps them to core sections, and optionally injects cross-reference remarks. ## Prerequisites - Python 3.9+ - A repository with `papers/publication/` (papers) and `theory/` (core) ## Step 1 — Clone and navigate ```bash git clone https://github.com/the-omega-institute/automath.git cd automath/papers/publication ``` ## Step 2 — Scan all papers for theorems ```bash python backflow.py scan ``` **Output:** For each paper, prints: ``` [SCAN] 2026_fibonacci_folding_...: 47 claims (12 theorem, 8 lemma, 15 proposition, ...) ``` Total across all papers: 911 claims. ## Step 3 — Generate backflow report ```bash python backflow.py report ``` **Output:** `backflow/backflow_report.md` — a Markdown report with: - Per-paper claim inventory - Core section mapping (which paper maps to which core section) - Coverage statistics - Recommended injection points ## Step 4 — Check backflow status ```bash python backflow.py status ``` **Output:** Pipeline-wide status showing: - Papers scanned / total - Claims extracted / injected - Core sections enriched ## Step 5 — Inject cross-references (optional) ```bash python backflow.py inject --execute ``` This inserts `\cref` remarks into the core theory sections, connecting core results to their refined versions in publication papers. **Dry run (no changes):** ```bash python backflow.py inject ``` ## Paper-to-Core Routing Table | Paper | Core Section | |-------|-------------| | fibonacci_*, folded_rotation, zeckendorf | folding | | dynamical_zeta, fredholm_witt, self_dual_sync | zeta_finite_part | | conservative_extension, gluing_failure | logic_expansion_chain | | circle_dimension | circle_dimension_phase_gate | | scan_projection, prefix_scan | spg | | projection_ontological | pom | | yang_lee, zero_jitter | statistical_stability | ## Expected Production Statistics | Metric | Value | |--------|-------| | Papers scanned | 15 | | Total claims extracted | 911 | | Core sections enriched | 3 | | Claim types | theorem, lemma, proposition, corollary, definition | ## Verify ```bash python backflow.py status # Should show: X papers scanned, Y claims extracted ```
