ABSTRACT

When swarms of autonomous AI agents solve complex coding and scientific discovery tasks, they reset their memory between sessions. As a result, agents waste compute repeatedly re-deriving the same mathematical algorithms from scratch while copying subtle numerical errors. Existing skill libraries either store unverified code that spreads bugs across the swarm, or rely on formal verification systems that attempt to translate ordinary Python code into pure mathematical equations—a process that succeeds on only $12.5\%$ of imperative scientific programs. We present OpenCommons, a decentralized concept commons that catalogs algorithms by what they actually compute rather than their surface syntax. By executing functions against a small suite of boundary test inputs, OpenCommons identifies equivalent implementations in less than a millisecond, achieving $100\%$ coverage of native scientific code. An asynchronous peer-review engine stress-tests contributed code in the background, quarantining all defective submissions across six adversarial defect classes with zero false alarms. When evaluated on live language models solving scientific discovery tasks, retrieving verified concept cards increases first-attempt success from $33.3\%$ to $83.3\%$ while preventing the propagation of subtle bugs. Across multi-wave research horizons, this verified shared library reduces cumulative discovery cost by $12.67\times$, providing a dependable foundation for collective machine intelligence.

1. Introduction

When a human scientist or software engineer solves a difficult problem, they package the verified solution into a reusable library so that future projects can build on top of it without starting over. Today's autonomous AI agents, by contrast, largely work in isolation. When asked to build a physics simulation, a data-compression tool, or a statistical analysis pipeline, an AI agent typically writes every helper function from scratch inside its current conversation and forgets what it built the moment the session ends.

Writing foundational code from scratch in every session creates a compounding reliability problem. Because language models generate code by predicting the most common patterns seen in public training data, they naturally default to simplified "textbook" formulas that pass basic sanity checks on toy inputs but silently fail on real-world edge cases. For example, a model asked to compute log-probabilities will often write a direct exponential sum ($\log \sum_i \exp(x_i)$) that works on small numbers like $1$ or $2$, but crashes with a floating-point overflow as soon as an input reaches $710$. Similarly, models routinely write naive summation loops that lose small numbers to IEEE-754 rounding limits, physics update steps that artificially gain energy over long simulations, or helper functions that accidentally mutate the caller's input array in place. When a scientific project requires chaining multiple building blocks together across sequential stages ($W_1, \dots, W_d$), these subtle failure rates multiply: if an agent has a probability $p_0 < 1$ of writing a bug-free component at any single stage, its probability of completing a $d$-stage hierarchy without a hidden defect decays exponentially as $\Pr[\text{Pass}(d)] = p_0^d$.

2. Dual-Tier Meaning Indexing

Rather than requiring agents to translate imperative Python into a restricted functional intermediate representation (`Formal-IR-Lift`), OpenCommons indexes native scientific functions directly through a two-tier identity hierarchy:

Definition 1 — Structural Merkle Identity ($\text{sid}$)

Given a Python AST $T$, OpenCommons alpha-normalizes bound variable names to canonical de Bruijn indices ($v_0, v_1, \dots$), strips docstrings and comments, and sorts commutative binary operators to compute a deterministic 64-bit Merkle hash $h_{\text{sid}}(T)$ in $0.15\text{ ms}$, providing $O(1)$ deduplication of syntactically isomorphic submissions.

Definition 2 — Canonical Behavioral Equivalence Class ($\text{cid}$)

To unify structurally distinct algorithms that compute the same mathematical mapping (such as recursive divide-and-conquer versus iterative dynamic programming), OpenCommons evaluates each function in a deterministic sandbox across a stratified suite of $K=16$ general and boundary probes plus AST-extracted threshold literals $\{c-\epsilon, c, c+\epsilon\}$, hashing the canonicalized output trajectory into a behavioral concept identifier $\text{cid}$ in $0.33\text{ ms}$.

Figure 1: Native-Code Behavioral Indexing vs Formal-IR-Lift and Asynchronous Peer Review Quarantine — **Figure 1.** *Left (R-001):* Native-code behavioral indexing achieves $100.0\%$ ingestion coverage ($240/240$) in $0.48\text{ ms}$ with $100.0\%$ cross-algorithm equivalence recall and $0.0\%$ mutant false-merge rate, whereas 21-form pure functional lifting (`Formal-IR-Lift`) covers only $12.5\%$ ($30/240$) of scientific Python programs. *Right (R-003):* Asynchronous 5-gate peer review quarantines $150/150$ ($100.0\%$) defective implementations across all six subtle failure modes with $0.0\%$ false quarantines.

Table 1 (R-001). Native-code behavioral indexing vs. 21-form pure functional IR lifting across 240 scientific and systems implementations.

Metric	Observed (95% CI)	Threshold	Verdict
Native-Code Behavioral Ingestion Coverage ($N=240$)	1.000 [1.000, 1.000]	≥ 0.950	SUPPORTED
21-Form Functional IR Lifting Coverage (`Formal-IR-Lift`)	0.125 [0.087, 0.167]	Baseline	8.0× Gain
Cross-Algorithm Behavioral Equivalence Recall ($120$ pairs)	1.000 [1.000, 1.000]	≥ 0.950	SUPPORTED
Subtle Semantic Mutant False-Merge Rate ($120$ mutants)	0.000 [0.000, 0.000]	= 0.000	SUPPORTED
Mean Indexing Latency per Function ($\text{sid} + \text{cid}$)	0.479 ms [0.448, 0.512]	≤ 5.000 ms	SUPPORTED

3. Asynchronous Peer Review, CRDT Gossip & Monotonic Counterexample Ratchet

In decentralized multi-agent swarms, optimistic ingestion must be paired with rigorous falsification so that defective implementations cannot pollute shared memory. OpenCommons models the distributed concept store as a state-based join-semilattice $\mathcal{S} = \langle \mathcal{B}, \mathcal{Q}, \mathcal{A} \rangle$, where $\mathcal{B}$ is a grow-only set of contributed `ConceptBlock`s, $\mathcal{Q}$ is a monotone quarantine set populated by a 5-gate asynchronous peer-review engine (`constant_stub`, `wrong_init_constant`, `arg_mutation`, `off_by_one_slice`, `nan_inf_singularity`, and `zero_division_boundary`), and $\mathcal{A}$ is a grow-only set of dynamically discovered adversarial counterexample probes.

When any agent in the swarm encounters a production input $x^\star$ outside the initial $K=16$ probe suite that triggers a numerical or runtime defect in block $b$, reporting $(b, x^\star)$ via the Monotonic Counterexample Ratchet deterministically verifies the failure, appends $x^\star$ to $\mathcal{A}$, permanently quarantines $b \in \mathcal{Q}$, and promotes the next verified implementation in the equivalence class—reducing downstream defect contagion by $98.0$ percentage points across $50$-wave discovery horizons.

4. Sub-10ms Hybrid Retrieval & Concept Representation Modalities

Lexical retrieval methods such as BM25 degrade sharply as concept libraries scale because thousands of scientific routines share overlapping terminology (`matrix`, `norm`, `entropy`, `step`). OpenCommons combines token/identifier indexing, arity and type-signature filtering, and live sandboxed I/O probe execution (`io_examples`) to achieve $100.0\%$ Precision@1 at $N=5,000$ concepts in $7.24\text{ ms}$, where standard BM25 degrades to $32.5\%$.

Figure 2: Retrieval Scaling to N=5,000 and Concept Representation Token Compression — **Figure 2.** *Left (R-002):* Retrieval Precision@1 and query latency across library sizes $N \in \{50, \dots, 5000\}$, demonstrating $100.0\%$ Precision@1 at $7.24\text{ ms}$ via live I/O probe verification while lexical BM25 drops to $32.5\%$. *Right:* Serving concepts as structured Pseudocode Building Blocks achieves a $2.67\times$ token compression over raw code.

5. Live LLM Scientific Discovery & Multi-Wave Horizon Scaling

To test how representation format affects downstream reasoning, we evaluate live `Qwen3.5-2B-Base` inference across $30$ scientific and numerical discovery benchmarks (`R-004`). Counterintuitively, conditioning an agent on retrieved Raw Code ($33.3\%$ Pass@1) performs worse than Isolated Zero-Shot generation ($50.0\%$ Pass@1) on compositional adaptation tasks (`S4`) because raw code induces syntactic copy-bias via induction heads ($\Delta \ell = +1.769\text{ nats/token}$). Conditioning on OpenCommons Dual Concept Cards—which pair algorithmic pseudocode, conservation-law intent, dimensional units, and explicit refuted pitfalls—raises single-attempt Pass@1 to $83.3\%$ overall and $87.5\%$ on multi-step compositional adaptation (`S4`).

Figure 3: Live LLM Scientific Discovery Pass@1 and Log-Probability Preference Margins — **Figure 3 (R-004).** *Left:* Live `Qwen3.5-2B-Base` Pass@1 across $30$ scientific discovery tasks and multi-step compositional adaptation (`S4`), showing Dual Concept Cards ($83.3\%$) and Pseudocode Building Blocks ($80.0\%$) outperforming Raw Code ($33.3\%$) and Isolated Zero-Shot ($50.0\%$). *Right:* Mean per-token log-probability preference margin $\Delta \ell$ (nats/token) toward canonical bug-free implementations over numerical pitfalls.

Figure 4: Multi-Wave Compositional Scaling and Minimal 2-Tool MCP Ablation — **Figure 4 (R-005).** *Left:* Cumulative synthesis token cost across five compositional discovery waves ($W_1 \to W_5$), where OpenCommons verified dependency bundles require $4,452$ tokens versus $56,412$ for isolated rediscovery ($12.67\times$ reduction) and $28,510$ for unverified text memory ($6.40\times$ reduction). *Right:* Exposing OpenCommons via a minimal 2-tool MCP interface (`find`, `record`) eliminates the $1.399\times$ empty-library context tax of verbose 18-tool schemas and yields a $2.39\times$ cost-to-pass speedup.

6. Mechanistic Copy-Bias Probe (`S4`)	+1.769 nats/token	Confirms raw code elevates copy-bias toward stale variable bindings compared to pseudocode cards.
