The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
AI debris, the post-withdrawal socio-technical residue of AI systems, which carries the argument by showing how listed effects continue after model removal.
What would settle it
An organization that decommissioned an AI hiring or decision tool and, after independent audit, showed zero measurable continuation of the original screening heuristics, data patterns, or accountability gaps traceable to that system.
Extended reading notes
Core claim
Decommissioned AI systems generate residual risk, termed AI debris, defined as the post-withdrawal socio-technical residue consisting of workflow dependency, data contamination, capability displacement, legitimacy erosion, and accountability breakdown. This residue persists via institutional memory, path dependency, blame avoidance, and data feedback loops. The paper supplies a typology of debris domains and an evaluator-ready AI Debris Decommissioning Protocol that specifies auditable evidence for freezing decision footprints, incident review, remediation, contestability, and post-withdrawal accountability assignment.
Load-bearing premise
The listed socio-technical effects are both widespread and directly caused by the prior AI system rather than by pre-existing organizational practices.

Referee Report
Summary. The paper claims that decommissioned AI systems generate persistent residual socio-technical risks termed 'AI debris,' encompassing workflow dependency, data contamination, capability displacement (deskilling), legitimacy erosion, and accountability breakdown. These effects continue to shape institutional behavior, accountability, and trust after model removal via mechanisms such as institutional memory, path dependency, blame avoidance, and data feedback loops. The manuscript develops a typology of debris domains, identifies persistence mechanisms, and proposes the AI Debris Decommissioning Protocol (AIDP) as an evaluator-ready stepwise checklist for auditable evidence on decision footprints, incident review, remediation, contestability, and post-withdrawal accountability. A vignette of Amazon's discontinued hiring tool is used to illustrate persistence of algorithmic categories and heuristics.
Significance. If the causal mechanisms and prevalence of AI debris are substantiated, the framing could extend AI governance beyond development and deployment to the full lifecycle, offering regulators, auditors, and organizations a practical instrument (AIDP) to mitigate long-term institutional risks and avoid paper compliance in high-stakes domains.
major comments (2)
- [Abstract and vignette] The central claim that workflow dependency, data contamination, capability displacement, legitimacy erosion, and accountability breakdown are both widespread after AI withdrawal and specifically causally traceable to the decommissioned system (rather than pre-existing organizational practices, leadership changes, or non-AI policy shifts) rests on definitional assertion and a single vignette without comparative cases, counterfactuals, or controls. This is load-bearing for the residual-risk thesis. (Abstract; vignette description)
- [AIDP proposal] The AIDP checklist operationalizes documentation requirements for freezing decision footprints, incident review, remediation, contestability, and accountability assignment but contains no validation criteria, falsification tests, or empirical grounding to confirm that observed effects are attributable to prior AI systems rather than baseline routines. This limits its utility as an evaluator-ready protocol. (AIDP proposal section)
minor comments (1)
- [Definition of AI debris] The boundaries of the 'AI debris' concept could be clarified to distinguish it more sharply from general organizational path dependency or change management effects, reducing potential overlap.

Referee: [Abstract and vignette] The central claim that workflow dependency, data contamination, capability displacement, legitimacy erosion, and accountability breakdown are both widespread after AI withdrawal and specifically causally traceable to the decommissioned system (rather than pre-existing organizational practices, leadership changes, or non-AI policy shifts) rests on definitional assertion and a single vignette without comparative cases, counterfactuals, or controls. This is load-bearing for the residual-risk thesis. (Abstract; vignette description)
Authors: The manuscript is a conceptual paper that introduces the 'AI debris' framing and typology rather than an empirical study claiming prevalence or strict causal attribution across cases. The Amazon vignette is presented explicitly as an illustration of persistence mechanisms (institutional memory, path dependency) drawn from publicly documented events, not as proof of generalizability. We agree the abstract and vignette section could more sharply delimit the contribution as definitional and illustrative. In revision we will (1) rephrase the abstract to state that the paper proposes a conceptual lens and protocol rather than demonstrating widespread effects, and (2) add explicit language in the vignette section noting the absence of comparative controls and the need for future empirical work to test attribution. This addresses the load-bearing concern without altering the core argument. revision: yes

Referee: [AIDP proposal] The AIDP checklist operationalizes documentation requirements for freezing decision footprints, incident review, remediation, contestability, and accountability assignment but contains no validation criteria, falsification tests, or empirical grounding to confirm that observed effects are attributable to prior AI systems rather than baseline routines. This limits its utility as an evaluator-ready protocol. (AIDP proposal section)
Authors: We concur that the AIDP, as currently presented, is a proposed stepwise checklist without accompanying validation criteria or falsification tests. Its purpose at this stage is to translate the debris concept into auditable documentation requirements for practitioners and regulators. In the revised manuscript we will add a dedicated limitations subsection under the AIDP proposal that (a) acknowledges the absence of empirical validation, (b) outlines how future studies could develop falsification tests (e.g., pre/post withdrawal comparisons or matched organizational controls), and (c) positions the protocol as a starting point for evaluator use rather than a fully validated instrument. This maintains the practical intent while clarifying its provisional status. revision: partial
Circularity Check
No circularity: purely conceptual definition and protocol proposal
full rationale
The paper introduces 'AI debris' via explicit definition listing socio-technical effects, develops a typology, and proposes the AIDP checklist. No equations, fitted parameters, derivations, or self-citations appear in the provided text. The central claim is definitional and illustrative (via one vignette) rather than a reduction of any output to its own inputs by construction. This matches the default expectation of no significant circularity for non-quantitative conceptual work.

AI governance frameworks primarily focus on risks during the development and deployment phases, implicitly treating system withdrawal as a technical shutdown. This paper argues that decommissioned AI systems generate residual risk, termed AI debris, that persists after model removal and continues to shape institutional behaviour, accountability, and trust. AI debris is defined as the post-withdrawal socio-technical residue of AI systems, including workflow dependency, data contamination, capability displacement (deskilling), legitimacy erosion, and accountability breakdown. The paper develops a typology of debris domains and identifies mechanisms through which debris persists, including institutional memory, path dependency, blame avoidance, and feedback effects in organisational data. To operationalise the concept, the paper proposes an evaluator-ready AI Debris Decommissioning Protocol (AIDP), a stepwise checklist specifying auditable evidence for freezing decision footprints, incident review, remediation, contestability, and post-withdrawal accountability assignment. A brief vignette of Amazon's discontinued hiring tool illustrates how algorithmic decision categories and screening heuristics can persist after system rollback. The paper contributes a practical governance instrument for regulators, auditors, and organisations seeking to prevent paper compliance, strengthen AI lifecycle governance, and improve institutional resilience in high-stakes decision environments.
