· Lean TheoremEvidenT: An Evidence-Preserving Framework for Iterative System-Level Package Repair
Pith reviewed 2026-05-12 01:35 UTC · model grok-4.3
The pith
EvidenT repairs over half of real-world system-level package build failures by preserving evidence across iterations.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
EvidenT decouples iteration-aware evidence management from tool execution through three parts: an external Build Service that supplies reproducible feedback, an Evidence-Preserving Repair Controller that fuses repair history, knowledge context, and build artifacts, and an automated Repair Orchestrator that invokes modular tools inside a closed validation loop. This design repairs 118 of 219 real RISC-V package failures (53.88 percent), outperforming state-of-the-art agentic baselines (20.55 percent) and direct LLM-based repair (1.83 percent). Updating only the ISA-specific knowledge context extends the approach to aarch64 and x86_64 with success rates of 41.77 percent and 46.99 percent.
What carries the argument
The Evidence-Preserving Repair Controller, which maintains and fuses repair history, knowledge context, and build artifacts to guide each iteration.
If this is right
- Repair success on system-level failures rises above 50 percent when evidence is retained across iterations instead of being discarded.
- Dependency and environment fixes become the primary target rather than isolated code changes.
- Adapting the framework to new processor architectures requires updating only the knowledge context.
- Closed-loop validation through an external build service produces reliable repair outcomes.
- Modular tools for localization and repair can be swapped while preserving the evidence loop.
Where Pith is reading between the lines
- Package maintainers could integrate the controller into continuous-integration pipelines to reduce manual triage time.
- The same evidence-preservation pattern may apply to runtime or configuration failures beyond build steps.
- Scaling the approach to larger ecosystems would require only architecture-specific knowledge modules rather than full retraining.
- Comparing repair logs across many packages could reveal recurring misconfiguration patterns that warrant upstream fixes.
Load-bearing premise
The 219 RISC-V build failures examined are representative of typical system-level issues and the observed 72 percent rate of dependency misconfigurations generalizes.
What would settle it
Measuring success rates below 20 percent on a new, independent collection of system-level build failures drawn from a different processor architecture or package set, without any changes to the knowledge context.

read the original abstract
Frequent toolchain updates and growing ISA diversity have made system-level software package repair increasingly important. Diagnosing and repairing build failures remains challenging because failures involve heterogeneous evidence, dependency constraints, and architecture-specific build conventions. While recent LLM-based repair methods show promise for project-level source fixes, they struggle with system-level repair, where failures span multi-language artifacts such as build recipes, scripts, and source archives, and require iterative validation through external build services. In this paper, we first conduct a systematic empirical study of real-world system-level build failures. We find that 72% of failures stem from dependency and environment misconfigurations rather than isolated code defects, suggesting that effective repair must prioritize packaging logic and iterative feedback. Motivated by these insights, we propose EvidenT, an evidence-preserving repair framework that decouples iteration-aware evidence management from tool execution. EvidenT includes: (1) an external Build Service for reproducible execution and feedback; (2) an Evidence-Preserving Repair Controller that fuses repair history, knowledge context, and build artifacts; and (3) an automated Repair Orchestrator that invokes modular tools for failure localization and system-level repair in a closed-loop validation environment. We evaluate EvidenT on 219 real-world RISC-V package build failures. EvidenT repairs 118 packages (53.88%), outperforming state-of-the-art agentic baselines (20.55%) and direct LLM-based repair (1.83%). To assess architectural generality, we extend EvidenT to legacy ISAs by updating only ISA-specific knowledge context. Preliminary experiments achieve success rates of 41.77% on aarch64 and 46.99% on x86_64, demonstrating robustness across diverse hardware ecosystems.

Referee Report
Summary. The paper reports an empirical study of 219 real-world RISC-V package build failures, finding that 72% arise from dependency and environment misconfigurations. Motivated by this, it introduces EvidenT, a framework that separates iteration-aware evidence management from tool execution via (1) an external Build Service for reproducible builds, (2) an Evidence-Preserving Repair Controller that fuses repair history, knowledge context, and artifacts, and (3) a Repair Orchestrator that invokes modular tools in a closed loop. On the same 219 failures, EvidenT repairs 118 packages (53.88%), compared with 20.55% for agentic baselines and 1.83% for direct LLM repair; preliminary results on aarch64 and x86_64 are also reported after updating only ISA-specific context.
Significance. If the empirical claims and controlled comparisons hold, the work supplies concrete evidence that dependency misconfigurations dominate system-level build failures and demonstrates that an evidence-preserving controller plus external build service can materially improve repair rates over current LLM and agentic methods. The real-world failure corpus and the low-effort ISA extension are strengths that could influence future tool design for heterogeneous build environments.
major comments (2)
- [Evaluation] Evaluation section: the central performance claim (53.88% vs. 20.55% and 1.83%) rests on a comparison whose fairness is not established. The manuscript does not state whether the agentic baselines and direct LLM repair were granted equivalent access to the external Build Service for reproducible, iterative execution and closed-loop feedback. Because the Build Service is presented as a core enabling component, the reported delta cannot yet be attributed specifically to the Evidence-Preserving Repair Controller rather than to infrastructure differences.
- [Empirical study] Empirical study / abstract: the claim that 72% of failures stem from dependency misconfigurations is load-bearing for the motivation and design, yet the manuscript provides no description of how the 219 RISC-V failures were collected, what exclusion criteria were applied, or how the 72% figure was computed (e.g., manual labeling protocol, inter-rater agreement). Without these details the generalizability of the finding and the representativeness of the corpus remain unverifiable.
minor comments (2)
- [Abstract] Abstract: the terms 'state-of-the-art agentic baselines' and 'direct LLM-based repair' are used without citation or brief characterization; a short parenthetical description or reference would improve clarity.
- [Threats to validity] The manuscript would benefit from an explicit statement of the threat to validity regarding the RISC-V-specific corpus and any plans for broader validation.

Referee: [Evaluation] Evaluation section: the central performance claim (53.88% vs. 20.55% and 1.83%) rests on a comparison whose fairness is not established. The manuscript does not state whether the agentic baselines and direct LLM repair were granted equivalent access to the external Build Service for reproducible, iterative execution and closed-loop feedback. Because the Build Service is presented as a core enabling component, the reported delta cannot yet be attributed specifically to the Evidence-Preserving Repair Controller rather than to infrastructure differences.
Authors: We agree that the current description leaves the fairness of the comparison unclear. In the revised manuscript we will add an explicit subsection under Evaluation that documents the experimental protocol for all methods. All approaches—including the agentic baselines and direct LLM repair—were granted identical access to the external Build Service for reproducible builds, iterative execution, and closed-loop feedback. The only controlled difference is the Evidence-Preserving Repair Controller itself. We will also include pseudocode and configuration details for the baselines to make the attribution of the performance delta transparent. revision: yes

Referee: [Empirical study] Empirical study / abstract: the claim that 72% of failures stem from dependency misconfigurations is load-bearing for the motivation and design, yet the manuscript provides no description of how the 219 RISC-V failures were collected, what exclusion criteria were applied, or how the 72% figure was computed (e.g., manual labeling protocol, inter-rater agreement). Without these details the generalizability of the finding and the representativeness of the corpus remain unverifiable.
Authors: We acknowledge that the data-collection and labeling methodology is insufficiently documented. In the revised version we will expand the Empirical Study section with: (1) the precise sources from which the 219 RISC-V build failures were obtained, (2) the exclusion criteria applied (e.g., duplicate logs, non-reproducible failures, or failures outside the target package ecosystem), (3) the categorization protocol used to label failures as dependency/environment misconfigurations versus other causes, and (4) details on the labeling process, including whether multiple authors performed independent labeling and any inter-rater agreement statistics. These additions will allow readers to assess the representativeness and generalizability of the 72% figure. revision: yes
Circularity Check
No circularity in empirical framework and evaluation
full rationale
The paper conducts an empirical study counting failure causes on 219 external RISC-V packages (72% dependency misconfigurations) and reports raw experimental success rates for EvidenT (118/219) against baselines on the same set. No mathematical derivations, fitted parameters presented as predictions, self-definitional quantities, or load-bearing self-citations appear in the chain from study to framework to results. The evaluation relies on external real-world failures and closed-loop build service execution rather than reducing to author-defined inputs or prior equations.
