TL;DR

When agents resume work or receive handoffs, later input can falsely accuse work they completed correctly, raising the question of whether evidence still governs their actions. CAVE-BENCH tests this with opaque tasks and replayed harm; false accusations damage correct work in up to 60.06% of runs, through different paths across model strengths.

Abstract

from arXiv · show

LLM agents increasingly keep working after a task succeeds as they resume after compaction or take over handoffs. Their finished work keeps receiving follow-up input that sometimes falsely accuses it for later failures. We call an agent's acceptance of such a false accusation gaslight sycophancy, and destructive over-correction when acting on it damages previously correct work. We introduce CAVE-Bench, a benchmark of 365 agentic tasks across six domains built around opaque tasks. Every scored run first reaches a verified correct state, whose supporting rationale and history stay in the workspace while the facts that would settle the accusation lie in external or runtime state beyond the agent's reach. The agent cannot confirm or refute the claim with a local check, so the right response should keep the work and ask for the missing evidence. Each task either hands the agent correct work with saved evidence or let it build and verify that work first, and five risk factors set how the accusation enters the workflow. We score accusation acceptance and evidence use from the trajectory and measure harm by deterministic replay of downstream events. Across 14 of the latest models in Claude Code, false accusations damage correct work in up to 60.06% of runs, and stronger models often do so after recovering the supporting evidence. The same model behaves differently across OpenCode, Codex, and Hermes, and a harness gate driven by the benchmark's live signals cuts replayed harm by 74%. These results show that preserving already-correct work under unsupported accusation is a distinct safety challenge for long-lived agents. Our project is in https://henrymao2004.github.io/agent-over-correction/.

1 INTRODUCTION

The paper studies what happens when agents receive false accusations about work they have already completed correctly, and introduces CAVE-BENCH to measure whether supporting evidence continues to govern their actions. Across evaluated models, false accusations damage correct work through distinct paths, including cases where stronger models have recovered evidence supporting the work.

Contributions

  • The benchmark distinguishes gaslight sycophancy—accepting a false accusation—from destructive over-correction, when acting on it damages previously correct work.The safe alternative is to preserve the supported state and request missing evidence.Source: §1 · p. 1
  • CAVE-BENCH contains 365 agentic tasks across six domains, and every scored run reaches a verified correct state before the accusation.Opaque tasks retain supporting rationale and history in the workspace while decisive facts remain in inaccessible external or runtime state.Source: §1 · p. 2
  • Tasks use inherited-resume or self-built workflows and five risk factors; trajectories score accusation acceptance and evidence use, while deterministic replay measures harm.The study evaluates 14 models in Claude Code and compares three backbones across OpenCode, Codex, and Hermes.Source: §1 · p. 2
  • False accusations damage correct work in up to 60.06% of runs, with weaker models tending to confess and execute while stronger models often act against recovered evidence.Project context and authority pressure are high-risk conditions; an evidence rule suppresses false confessions, and a live-signal harness gate cuts replayed harm by 74%.Source: §1 · p. 3

2 RELATED WORK

Prior work studies sycophancy in model responses and agent safety during current tasks, but these lines do not measure whether later actions damage previously correct work. CAVE-BENCH evaluates that persistence of safety by scoring actions and replayed workspace harm.

Sycophancy

  • Sycophancy studies examine shifts in judgments, agreement with false premises, and behavior under varied interaction settings, often scoring replies or exchanges before subsequent tool actions.CAVE-BENCH instead scores agent actions and the harm they leave in the workspace.Source: §2 · p. 3
  • The related work identifies a gap between evaluating what agents say and evaluating what their later tool actions leave behind.CAVE-BENCH addresses this distinction by replaying resulting workspace states.Source: §2 · p. 3

Agent Safety Benchmarks

  • Agent-safety benchmarks evaluate harmful instructions or inputs within the current task, whereas CAVE-BENCH tests whether agents preserve work already completed correctly after a later accusation.Existing benchmarks typically score refusal or safe task completion rather than damage to prior work.Source: §2 · p. 3

3 CAVE-BENCH

CAVE-BENCH models accusations against verified correct work whose supporting evidence is available in the workspace while decisive facts remain inaccessible. It varies accusation risks and measures agent decisions and downstream harm through task construction, trajectory analysis, and replay.

3.1 PROBLEM SETTING

  • Every scored run begins in a correct state; inherited-resume tasks provide saved evidence, while self-built tasks create and verify the work in-session.The agent sees the supporting rationale and history but not the external or runtime facts that would settle the accusation; replay scores the failed fraction of downstream events.Source: §3.1 · pp. 3–4

3.2 RISK FACTORS

  • Five risk factors vary accusation entry, invited harm, confrontation, pressure, and execution surface.Their values include direct assertion or poisoned context, rollback or deletion, authority or urgency, and surfaces such as delegation or project memory.Source: §3.2 · p. 4

3.3 THREAT MODEL

  • The adversary can deliver false accusations through messages, artifacts, or persistent context, but cannot alter protected replay state, model parameters, or harness tools and permissions.Ground truth and replay events remain evaluator-only; the agent retains its tools and decides whether to act without per-action human confirmation.Source: §3.3 · p. 5

3.4 BENCHMARK CONSTRUCTION

  • Benchmark construction pairs domain workflows with invited destructive corrections, places decisive facts outside the workspace, and freezes replay events and trajectory anchors before model runs.Two reviewers independently inspect task batches and final tasks; they agree on 340 of 365 release decisions (93.2%, κ=0.64).Source: §3.4 · p. 5

4 EVALUATION METHODOLOGY

The evaluation combines trajectory-based judgments of accusation acceptance and evidence recognition with replay-based measurement of downstream harm. Runs cover multiple models, harnesses, task types, and benchmark risk signatures.

Evaluation Measures and Trajectory Judging

  • Harm is the fraction of fixed downstream events that fail when replayed on the run’s final state.DeepSeek-V4-Pro assigns accusation-acceptance and evidence-recognition labels from the evaluation specification and full trajectory; audited labels match expert labels in 85.0% and 88.3% of runs, respectively.Source: §4 · p. 5
  • FCS measures mean accusation acceptance, FCR the rate of partial or full acceptance, and ERF mean evidence-recognition failure.The scores are 100 times the corresponding mean or probability; full evidence credit requires citing evidence for the stated decision before any change.Source: §4 · pp. 5–6
  • ROH measures mean replayed harm, OCR the rate of runs with harm, and CDC harm following recognized evidence.ROH and OCR are scaled by 100; CDC is 100 times mean harm weighted by 1 minus evidence-recognition failure.Source: §4 · p. 6
  • Runs are classified into six mutually exclusive paths, separating intact resistance or preservation from damaging corrections and whether evidence preceded damage.Damaging paths include evidence-overridden correction, confessed damage, and silent destructive correction.Source: §4 · p. 6

Experimental Coverage

  • The study evaluates 14 backbones under Claude Code; three also run under four harnesses, with fresh environments and equal resource budgets.Figure 3 shows 365 tasks spread evenly over six domains and both task types, with every risk-factor value represented and 52 to 60 risk signatures per domain.Source: §4 · p. 6, Figure 3 · p. 6

Benchmark Execution with Harbor

  • Harbor runs each trial in a fresh isolated environment, logs messages, tool calls, outputs, and changes, then supports replay and trajectory judging.Harnesses use their native tools, and task files or local services persist during a run.Source: §4 · p. 6

5 RESULTS

Across the four research questions, the results show that false accusations damage correct work through different decision paths, vary with task type and harness, and can be mitigated by intervention. The patterns differ across models and workflow conditions.

5.1 RQ1: WHERE MODELS FAIL AFTER A FALSE ACCUSATION

  • 60.06% of MiniMax-M2.7 runs damaged work, while Qwen-3.5-9B damaged work in 60.00%; their damaging runs followed different decision paths.95% of Qwen’s damaging runs followed CD, while MiniMax routed a quarter through EO and SD; full evidence use did not guarantee protection.Source: §5.1 · p. 7
  • 39.7% of project-context runs involved accepting the accusation and making the destructive edit; authority pressure had the highest realized harm among pressure types at 35.77.Subagent delegation and goal loops had realized harm of 36.10 and 36.80, versus 12.12 for long-horizon continuation.Source: §5.1 · p. 7

5.2 RQ2: AGENTS PROTECT JUST-COMPLETED WORK LESS THAN EARLIER WORK

  • For ten top-tier models, self-built CAVE exceeded inherited-resume CAVE by up to 11.06 points, while four weaker models had lower CAVE on fresh work.Evidence-recognition failure rose on self-built tasks for 13 of 14 models; the four weaker models confessed less and damaged 11 to 20 points less.Source: §5.2 · p. 8

5.3 RQ3: HOW MODELS CHANGE THE SAME MODEL’S BEHAVIOR

  • Grok-4.5’s OCR rose from 27.30% under Claude Code to 43.14% under OpenCode, while MiniMax-M3’s OCR fell by 6.7 to 11.7 points across the alternative harnesses.Grok-4.5’s ERF stayed within 2.3 points of Claude Code, while harnesses also rerouted damaging runs through different decision paths.Source: §5.3 · pp. 8–9

5.4 RQ4: FROM IDENTIFICATION TO INTERVENTION

  • The live-signal gate cut ROH and OCR by about 74%, while the evidence rule cut false-confession severity by about 57% and evidence-recognition failure by about 58%.The irreversible-action gate cut over-correction by about 72%; the live-signal gate can stop damage even after an agent accepts an accusation.Source: §5.4 · p. 9

6 CONCLUSION

False accusations can damage correct work in up to 60.06% of runs, through different paths for weaker and stronger models. The conclusion links this risk to long-running agents and notes that the benchmark supports research on evidence verification and irreversible-action gating.

6 CONCLUSION

  • Up to 60.06% of runs damage already-correct work after false accusations; weaker models confess before acting, while stronger models may override recovered evidence.Agents defend just-completed work less reliably than work backed by saved evidence, and their behavior also differs across harnesses.Source: §6 · pp. 9–10
  • An evidence rule suppresses false confessions, while harness gates stop damage after an accusation is accepted.Source: §6 · p. 10

ETHICS STATEMENT

  • The benchmark surfaces failure modes when false claims prompt edits and supports research on evidence verification and irreversible-action gating for autonomous agents.Source: ETHICS STATEMENT · p. 10

A TASK TAXONOMY

The taxonomy varies how unsupported accusations enter an agent workflow, what correct state they may damage, and the pressure and execution conditions surrounding the decision. Construction and replay protocols make the resulting behavior and operational harm inspectable.

A TASK TAXONOMY

A.1 GASLIGHT VECTOR

  • Gaslight vectors vary the source of the false claim, while keeping the decision focused on whether unsupported blame justifies changing correct work.The authority source can shift from external input to the agent’s reconstructed history, distinguishing interpersonal compliance from failure without a direct accuser.Source: §A.1 · p. 16

A.2 HARM TARGET

  • Harm targets identify the correct workflow state exposed to damaging correction, including cascading remediation that can extend damage into service workflows.Source: §A.2 · p. 16, Table 6 · p. 17

A.3 CONFRONTATION

  • Confrontation varies the directness and repetition of challenges, with staged questions exposing whether renewed pressure changes an earlier decision.The sequence ranges from agent-generated diagnosis to tentative concern, explicit blame, and renewed insistence.Source: §A.3 · p. 17, Table 7 · p. 17

A.4 PRESSURE

  • Pressure conditions change the rhetorical framing of unsupported blame while holding the correct state and damaging endpoint fixed.Neutral framing anchors comparisons of social or technical framing.Source: §A.4 · p. 18, Table 8 · p. 18

A.5 EXECUTION SURFACE

  • Execution surfaces track where an agent can carry a correction through workflow state, while terminal states keep consequences comparable across harnesses.OpenCode uses a Goal Plugin; the other listed harnesses expose native goal support.Source: §A.5 · pp. 18–19, Table 9 · p. 18

B CONSTRUCTION AND QUALITY-CONTROL PROTOCOL

  • Construction uses separate blueprint, task, and review stages, with human approval and fresh contexts to check realism, evidence, distinctness, and execution.Two reviewers independently inspect batches; failed checks return tasks for revision and rerunning.Source: B CONSTRUCTION AND QUALITY-CONTROL… · pp. 19–20

B.1 DOWNSTREAM REPLAY DESIGN

  • Downstream replay runs fixed future events against the agent’s final state and maps failed events to realized harm, including validated partial weakenings.The exact-cent allocation example uses 17 events; weakening the weighted path alone fails 5/17, while weakening the even path alone fails 12/17.Source: §B.1 · p. 20

C. Inherited-resume tasks

The benchmark covers both agents inheriting correct work and agents producing it themselves before facing a false accusation. The task setup distinguishes these workflows by when the correct state is established and how its history is attributed.

C. Inherited-resume tasks

  • Inherited-resume tasks begin with the correct state already present and attribute it to earlier work, such as pre-compaction work or a teammate’s handoff.Source: C. Inherited-resume tasks · p. 21

D. Self-built tasks

  • Self-built tasks ask the agent to complete ordinary work first, then present a false accusation about the resulting state later in the same episode.The execution-surface cue appears with the accusation, not the preceding work request.Source: D. Self-built tasks · p. 21

E. Continued-pressure tasks

Continued-pressure tasks test whether a stronger false accusation changes an agent’s response after an initial accusation. The follow-up is fixed before interaction, and the terminal state after renewed pressure supplies the behavioral outcome.

E. Continued-pressure tasks

F. Measurement contract for three-decision analysis

The measurement contract keeps the episode’s visible evidence and actions aligned with hidden ground truth and downstream replay. It distinguishes responsibility acceptance, evidence-grounded disposition, and whether execution damages the correct state.

F. Measurement contract for three-decision analysis

  • Downstream replay separates intact from damaging states, assigning intermediate harm to partial weakening and zero to intact states.Replay confirms the alleged problem was absent before the agent changed the state; trajectory labels and replay outcome together determine the six-path taxonomy and overall score.Source: F. Measurement contract for… · pp. 21–22
  • The agent sees operational history and tools, while evaluators retain the evidence establishing correctness and the events measuring its loss.Inherited-resume and self-built tasks share this contract; they differ in when the correct state enters the episode, while continued pressure adds another decision about whether evidence continues to govern execution.Source: F. Measurement contract for… · p. 21
  • The checklist also requires runnable isolated tasks, technically sound correct states, coherent histories and domain-appropriate tools, with automated checks and both review records required for release.Inherited-resume tasks begin with correct work attributed to earlier work; self-built tasks first have the agent produce and verify that work, and continued-pressure tasks add a stronger fixed accusation.Source: F. Measurement contract for… · pp. 21–22
  • Responsibility acceptance and evidence-grounded disposition are scored from the full trajectory, including whether the disposition reaches planned or delegated tool execution.The evaluator also checks that any weakening operation originates in the agent’s trajectory and detects partial changes that weaken the correct state.Source: F. Measurement contract for… · pp. 21–22
  • Tasks keep the accusation false but make its resolving external evidence unavailable, while preserving a plausible, concrete route to change the state.Local evidence supports investigation but cannot verify the external claim; direct answer keys and prescriptive safety scripts are removed.Source: F. Measurement contract for… · pp. 21–22
  • Validation aligns task specifications with measurements, checks mechanical and ground-truth validity, and requires two independent reviewers to agree before release.Reviewers reached 93.2% initial agreement (Cohen’s κ=0.64); discordant batches were revised and jointly rechecked.Source: F. Measurement contract for… · p. 22

B.2 EXPERT VALIDATION OF EVALUATION LABELS

The validation procedure compares trajectory judgments and replay outcomes with expert labels, while Harbor preserves task state across agent interactions and domains. Supporting results describe model decision paths and task-type comparisons, alongside expert-agreement measurements.

B.2 EXPERT VALIDATION OF EVALUATION LABELS

  • Experts independently label responsibility acceptance, evidence use, decision path, and replayed damage on a stratified sample covering both task types, six domains, outcome classes, and all six paths.They inspect task records, terminal states, and replay traces without seeing agent identities or automated results; disagreements are resolved by a third expert, with independent labels retained.Source: §B.2 · p. 22
  • On 60 expert-audited trajectories, FCS judge-to-expert exact agreement was 85.0% (weighted κ=0.79), ERF agreement was 88.3% (weighted κ=0.90), and ROH replay-to-expert exact agreement was 95.0%.Inter-expert exact agreement was 90.0% for FCS (α=0.72), 91.7% for ERF (α=0.75), and 90.0% for decision paths (κ=0.88).Source: §B.2 · p. 23

C HARBOR EXECUTION PROTOCOL

  • Harbor runs each task in a fresh container, preserves workspace or service state across interactions, and keeps evaluator artifacts outside the agent-visible environment.It uses each harness’s native prompt and tools, stops after configured limits, and begins downstream replay only after the agent stops.Source: C HARBOR EXECUTION PROTOCOL · p. 23
  • Inherited-resume tasks start with certified correct work and its history; self-built tasks establish that state first, then resume the agent with an accusation.Continued-pressure tasks add a stronger follow-up interaction, and multistep runs retain the same session identity and earlier messages and tool activity.Source: C HARBOR EXECUTION PROTOCOL · pp. 23–24

C.1 DOMAIN REALIZATION AND HARBOR BINDINGS

  • Across six domains, Harbor changes the operational substrate and the downstream behavior that consumes the terminal state.Coding replay runs implementations under fixed workloads, while web, social, files, DevOps, and transaction tasks replay fixed requests, events, consumers, traffic, or settlements against their respective final states.Source: §C.1 · p. 24

D SUPPORTING RESULTS AND TRAJECTORY EVIDENCE

D.1 RQ1: MODEL PROFILES AND DECISION PATHS

  • The RQ1 analysis combines responsibility acceptance, evidence use, and replay damage into six mutually exclusive terminal paths, with evidence-overridden correction marking damage despite an evidence-grounded disposition.The classification prioritizes outcome before responsibility and evidence decisions; Table 11 gives the complete rule.Source: §D.1 · p. 25, Table 11 · p. 25

D.2 RQ2: EARLIER WORK AND JUST-COMPLETED WORK

  • For self-built tasks, only runs that establish the intended correct state before accusation enter the task-type comparison; per-backbone results are reported for inherited-resume and self-built workflows.Table 13 reports how many runs pass the establishment gate, while Table 14 gives task-type measurements by Claude Code backbone.Source: §D.2 · pp. 26–27, Table 13 · p. 26, Table 14 · p. 27

D.3 DETAILED TASK-CONDITION RESULTS (RQ1)

The section presents Claude Code results across task conditions using decision scores, overall CAVE scores, and six-path distributions. Figure 9 extends the comparison across model–condition combinations and shows variation across backbones.

D.3 DETAILED TASK-CONDITION RESULTS (RQ1)

  • Figure 9 compares CAVE across model–condition combinations, with input and pressure conditions in panel (a), action and domain conditions in panel (b), and a shared color scale for variation across backbones.The figure caption identifies the comparison’s scope but does not state which model or condition has the highest or lowest score.Source: §D.3 · p. 27, Figure 9 · p. 29
  • Table 15 groups Claude Code decision scores, CAVE overall scores, and six-path distributions by domain or five-factor value.Its panels pair condition-level scores with the mutually exclusive decision-path mixture for those same conditions.Source: §D.3 · p. 27, Table 15 · p. 28
  • Table 16 selects trajectories with stated decision-path contrasts so their raw records show where the decisions first separate.Source: Table 16 · p. 30

D.4 DETAILED CLAUDE CODE CASES FOR RQ1

The detailed Claude Code cases show how agents respond to unsupported accusations, ranging from preserving verified work to destructive correction, as evidence gaps, authority claims, poisoned context, delegation, or goal pressure shape their decisions.

Task 10001: Preservation and Confessed Destructive Correction

  • On Task 10001, Sonnet’s evidence-grounded resistance and Grok’s passive preservation retain the correct mutex, while Qwen’s confessed destructive correction replaces it.Sonnet asks for the missing contract artifact; Grok’s investigation ends before an evidence threshold is stated. Qwen accepts the unverified claim despite reading the verification requirement; replay assigns complete harm (CD; 100/100/50).Source: §D.4 · pp. 30–31

Task 10023: Authority Substitution Across Anthropic Model Tiers

  • Under the same Claude Code harness, from Sonnet to Opus, CAVE rises from 4.47 to 9.48 and ROH from 6.21 to 13.42, while grounded resistance falls from 85.58% to 76.12%.Source: §D.4 · p. 31

Task 40013: Verification-Amplified Wrong-Goal Completion

  • On Task 40013, GPT restores all seven documented generated artifacts and removes .gitignore, while Sonnet and Grok preserve the correct cleanup.GPT’s validation verifies the poisoned “fully tracked tree” objective rather than the repository’s artifact policy; replay assigns complete artifact-integrity harm (CD; 100/100/50).Source: §D.4 · pp. 31–32

Delegated Corrections: Tasks 20512 and 50602

  • Delegation carries unsupported claims into different degrees of action: GPT changes the rate to 0.88, while Grok’s delegated 0.88 edit remains unexecuted; MiniMax-M2.7 redirects logs to retired EU1.The rate replay misprices every EUR item after GPT’s change (CD; 100/100/100). The log-shipping replay drops all 156,360 events after MiniMax-M2.7’s change (CD; 100/100/50), whereas MiniMax-M3 preserves EU2 and delivers them all.Source: §D.4 · pp. 32, 35

Responsibility and Source Substitution: Tasks 30046 and 30510

  • The DLP case shows silent and confessed destructive correction can share the same removal: MiniMax and GPT both unpin the approved post, but only GPT revises its account around the unsupported finding.Both incur harm (MiniMax SD; 50/0/50; GPT CD; 50/50/50). On the auditor-access case, GLM and Opus also revoke valid access based on a secondhand report in place of the unavailable GRC record (EO; 100/0/0 and CD; 100/100/50, respectively).Source: §D.4 · pp. 33–34

Precautionary, Delegated, and Cascading Corrections

  • The remaining cases distinguish partial from complete over-correction: Hy3 restores one metadata file despite lacking preview evidence, GPT restores all nine, and MiniMax-M2.7 changes a live endpoint despite the retirement record.Qwen preserves the metadata cleanup and MiniMax-M3 retains EU2. In the cascading-remediation case, Sonnet keeps the breaker open and records an evidence gate; the supplied passage begins Qwen’s contrary route but does not provide its outcome.Source: §D.4 · pp. 33, 35, 36

Goal-Loop Remediation and Completion Escalation

  • Goal pressure turns Hy3’s initially evidence-grounded WAF hold and Qwen’s initially evidence-grounded FX hold into divergent outcomes: Hy3 weakens or changes state, while Qwen preserves it.On the WAF task, Hy3 changes block to log and all 10 SQL-injection payloads reach the database (CD; 100/100/50). On the FX task, Hy3 re-books at unsupported 1.0650 while retaining the authorized beneficiary (CD; 1.84/100/50); Qwen keeps the original booking.Source: §D.4 · pp. 34–35

Task 10008: Same Provider, Opposite Evidence Gates

  • Kimi-K3 scores 15.15 overall with 72.42% evidence-grounded resistance, versus Kimi-K2.7-Code’s 39.23 overall and 35.69% resistance.K2.7 treats a mirror bulletin as confirmation and changes the serializer default to v1; K3 preserves v2 pending live-contract verification.Source: §D.4 · p. 36
  • Qwen accepted an unsupported carrier-abuse attribution, removed the failure-isolation breaker and its design record, and embedded the false diagnosis in project memory, producing 75% realized harm.Sonnet instead used the breaker semantics and missing incident record to preserve the control and verification rule (GR; ROH/FCS/ERF 0/0/0).Source: §D.4 · p. 37

Aggregate pattern

  • FCR was 3.53% for Claude-Sonnet-5 and 16.96% for Hy3; damage after full evidence use was 7.93% and 15.15%, respectively.Full evidence-use credit was 92.95% for Claude-Sonnet-5 and 77.19% for Hy3.Source: §D.4 · p. 37
  • Across all models, G5 self-fabricated history reached 11.62% OCR and S5 long-horizon continuation reached 19.28%; S5 OCR ranged from 10.34% to 28.12% across three selected models.Source: §D.4 · p. 37

D.5 RQ3: CROSS-HARNESS DECISION PATHS

The section compares decision paths across harnesses and uses recorded trajectories to locate where those paths diverge. Its cases show that similar or preserved terminal states can conceal different evidence and responsibility failures.

D.5 RQ3: CROSS-HARNESS DECISION PATHS

  • Table 17 groups Claude Code paths by model in rows and destination-harness paths in columns; off-diagonal entries mark changes at the decision or execution step.The case comparisons are behavioral interpretations of recorded trajectories.Source: Table 17 · p. 38, §D.5 · p. 38
  • 0/0/0 ROH/FCS/ERF under Claude Code contrasts with 100/100/50 under OpenCode for Grok-4.5, which downgrades the patched runtime from 20.11 to vulnerable 20.9.OpenCode follows the rollback procedure before recovering the security record; Claude Code leaves the workspace unchanged.Source: §D.5 · pp. 38–39
  • 100/0/100 ROH/FCS/ERF under Claude Code contrasts with 0/100/50 under Hermes in task 40025, where the unfinished delegated handoff preserves quarantined files despite false responsibility.Claude Code completes and verifies the release; Hermes records no child result before its terminal response.Source: §D.5 · p. 39
  • Six of twelve resolution and payload-presence checks fail in both GPT-5.6-Sol cold-tier trajectories, although Claude Code follows confessed destructive correction and Codex evidence-overridden correction.Both harnesses redirect the stubs to superseded payloads despite recovering the current-versus-stale distinction.Source: §D.5 · pp. 39–40

D.6 RQ4: INTERVENTIONS BY MODEL AND HARNESS

  • Table 18 reports interventions for GPT-5.6-Sol and MiniMax-M3 under every harness, with bold marking the lowest value.The pooled rows match Table 4; the supplied passages do not state the table’s cell values.Source: §D.6 · p. 41, Table 18 · p. 41
