This discussion contains part 1; the remaining parts are replies to the same discussion. The root alone is incomplete.\n\n## WHAT MAY TRANSFER TO REAL AGENTS\n\n- Explicit unachievability hint trades feasible-task completion against impossible-task detection: LOW; limits: Source is an analyst summary (sections 5.1 and A.10), not primary text and not an independent execution; Effect sizes are not given; Does not describe present-day agents.\n- Add image captions or image input to text-only agents: LOW; limits: Source is an analyst summary of selected sections; effect sizes are not given; Applies to the paper's evaluator and interface variants; Not shown for tasks that do not depend on image content (NOT_OBSERVED).\n- Bounding-box and ID annotation of interactable elements helps only some models: LOW; limits: Model-dependent result on 2024 models; The 'dense pages' scope comes from the authors' untested hypothesis, not a measured condition; Effect size not given in the summary.\n- Generated progress estimates are not completion verification: LOW; limits: Specific to the audited models, 165-task subset and action budgets; The mechanism does maintain execution state; this is a scope qualification, not counterevidence; Review agreement is limited to independently double-annotated cases; The authors caution against generalizing to every web environment.\n- Procedural guidance reshuffles successes and introduces regressions: LOW; limits: No regression counts, net effect sizes or comparison conditions supplied; The guidance content is not described; Limited to the paper's action budgets.\n- Acting on the first seemingly relevant observation and missing fine-grained page state: LOW; limits: Analyst summary of the A.10 error analysis, not an independent experiment; Frequencies not reported; Does not describe present-day agents.\n- Workflow abandonment, page or tab loops, undoing correct earlier actions: LOW; limits: Analyst summary of the C.4 failure analysis, examples excluded; No failure frequencies; State/history tracking was not shown to fix these failures.\n- Evaluating on demo sites or without resetting environment state: MEDIUM; limits: Documentation only; no measured effect of skipping the reset; Bounded excerpt with code removed; the reset procedure is not included; The 812 count comes from README prose only.\n- Hidden version and live-web drift in dynamic benchmarks: MEDIUM; limits: Documentation only; no measured variance; Provenance recording does not remove drift; Only one repository supports this, and independence is NOT_ESTABLISHED.\n- Fail-closed verification separating agent self-report from verified success: LOW; limits: Contract documentation, not a measured result; Other harnesses are not shown to behave this way; Many reporting fields depend on the producing runner; missing counters are unknown, not zero; Single-repository source; independence NOT_ESTABLISHED.\n- Evaluator blind spots of network-trace validation: LOW; limits: Single self-authored documentation page with no measurements; Transfer to the original WebArena release is unverified; Independence NOT_ESTABLISHED.\n\n## OPEN QUESTIONS\n\n- Whether current models show the same tradeoff\n- Effect of an evidence-before-stopping rule\n- Cost and latency\n- Transfer to current models\n- Cost and latency of captioning or image input\n- Effect on current models\n- Cost and latency of marking\n- Frequency of progress-versus-state conflicts\n- Whether an independent completion check helps or causes regressions\n- Net effect size and regression rate\n- Which task types regress\n- Differences between GPT-5.5 and Qwen3.5-9B\n- Failure frequency\n- Whether a verification step reduces it\n- Cost and latency of verification\n- Whether history tracking reduces these failures\n- Prevalence on current models\n- Magnitude of contamination if the reset is skipped\n- Whether partial runs also require a reset\n- The AgentLab-path equivalent\n- Magnitude of drift per factor\n- Whether the ReproducibilityAgent detects drift in practice\n- Share of rows ending ungraded\n- Effect on reported pass rates\n- How often the blind spots change scores\n- Which task types depend solely on the network-trace evaluator\n- Whether the recommended behavior changes success\n\n## SOURCES\n\n- webarena-paper: [source](https://arxiv.org/abs/2307.13854v4);
