The mechanism is well specified and inexpensive to test, but problem prevalence, stakeholder demand, comparative effectiveness, subgroup effects, and distinctiveness remain unsupported.","adopter_authorizer":"The responsible classroom teacher is the immediate adopter and pacing authority, subject to institutional accessibility, safeguarding, consent, and research-approval requirements; students retain authority to request clarification, restored supports, or alternative response modes.","scores":{"meaningful_impact":{"score":4,"rationale":"The proposal targets comprehension, retention, equitable response opportunity, and learner agency, all consequential instructional objectives. Impact is limited from a 5 because the magnitude and prevalence of crowding-related harm are unsupported and the learning effect remains hypothetical."},"stakeholder_pull":{"score":2,"rationale":"Students, teachers, aides, and accessibility users are identifiable, but the sealed candidate contains no evidence that they request this intervention, prioritize the diagnosed problem, or would sustain the practice."},"incremental_advantage":{"score":3,"rationale":"Protected blankness and response silence provide a testable increment beyond ordinary delivery and the stated chunking-and-signaling rival. Whether that increment improves outcomes meaningfully is unknown and could be offset by lost scaffolding or ambiguity."},"distinctiveness_plausibility":{"score":3,"rationale":"The candidate articulates a coherent mechanism distinct from merely simplifying or highlighting materials: absence must be intentional, interpretable, protected, and reversible. Prior art is explicitly unsearched, so external distinctiveness cannot be credited."},"technical_implementability":{"score":5,"rationale":"The intervention uses reversible edits to existing lesson materials, short labeled pauses, bounded response silence, explicit restoration triggers, and retained originals. No new technical infrastructure is required for the specified first test."},"adoption_authority_feasibility":{"score":4,"rationale":"The responsible teacher controls presentation and pacing and the candidate clearly bounds that authority. Institutional accessibility, safeguarding, consent, and possible research-approval requirements may still constrain testing or broader adoption."},"evidence_readiness":{"score":4,"rationale":"The candidate supplies an ordinary baseline, a stronger chunking-and-signaling rival, measurable immediate and delayed outcomes, harm measures, explicit falsifiers, and a reversible crossover pilot. Comparable lesson segments, measurement reliability, sample adequacy, and subgroup analysis remain unresolved."},"safety_net_benefit":{"score":3,"rationale":"The design could widen response opportunity and explicitly preserves accommodations, alternative response modes, rapid support restoration, and rollback. It could also disadvantage novices, slower processors, learners needing redundancy, or students who interpret silence as evaluation, so net protective benefit is uncertain."},"scalability":{"score":3,"rationale":"The material edits and timing routines are lightweight and potentially reusable, but successful scaling depends on teacher judgment about load-bearing content, consistent cueing, accessibility review, classroom power dynamics, and fidelity across subjects and learner groups."}},"score_confidence":"MODERATE","costs":{"first_evidence":{"band_2026_usd":"UNDER_10K","scope":"A consent-aware within-class crossover across two comparable lesson segments, including reversible material edits, observation, immediate explanation scoring, participation coding, delayed retrieval, clarity feedback, accommodation-failure checks, and analysis.","confidence":"MODERATE","assumptions":["One teacher and an existing class participate.","Existing lesson assets and ordinary classroom equipment are used.","Measures are brief and locally administered rather than developed as validated instruments.","No unusually burdensome institutional review, transcription, translation, or assistive-technology work is required."]},"initial_deployment_startup":{"band_2026_usd":"10K_TO_50K","scope":"Preparation for adoption within one school or instructional unit, including teacher training, lesson and accessibility audits, cue and rollback templates, stakeholder consultation, and initial evaluation design.","confidence":"LOW","assumptions":["Deployment covers multiple teachers but not a district-wide rollout.","Existing learning systems and lesson materials remain in use.","Specialist accessibility and evaluation support is part-time.","Substantial curriculum redevelopment is not required."]},"operational_launch":{"band_2026_usd":"50K_TO_250K","scope":"A structured multi-classroom or multi-school launch with training, implementation support, accessibility review, fidelity monitoring, comparative outcome collection, subgroup analysis, and governance coordination.","confidence":"LOW","assumptions":["The launch remains bounded to one institution or a small partner network.","No dedicated software platform or major equipment purchase is needed.","Evaluation includes delayed outcomes and accommodation-failure monitoring.","Teacher release time and partner coordination are included as resource-equivalent costs."]},"annual_recurring":{"band_2026_usd":"10K_TO_50K","scope":"Ongoing training for new staff, lesson audits, accessibility and safeguarding review, fidelity checks, learner feedback, outcome monitoring, and maintenance of restoration-ready materials within one institution.","confidence":"LOW","assumptions":["The practice is embedded into existing curriculum and professional-development processes.","Monitoring is sampled rather than continuous.","No large external research program or custom technology platform is maintained.","The number of participating teachers remains institution-scale."]}},"research_burden":"MODERATE","earliest_credible_horizon":"0_TO_3_MONTHS","pipeline_gates":{"recognizable_externally_supportable_problem":{"status":"UNCERTAIN","reason":"The packet clearly defines observable crowding, premature teacher filling, consequences, and a problem falsifier, but supplies no external or site-level evidence showing that these conditions materially cause the stated learning problems."},"identifiable_adopter_or_authorizer":{"status":"YES","reason":"The responsible teacher is explicitly identified as controlling lesson presentation and pacing within institutional accessibility and safeguarding limits, while students retain specified support-request rights."},"distinct_testable_incremental_claim":{"status":"YES","reason":"The candidate claims that protected, interpretable, reversible absence improves explanation, delayed retrieval, or participation beyond both ordinary continuous delivery and chunking-and-signaling revision, with explicit benefit and harm falsifiers."},"bounded_next_evidence_step":{"status":"YES","reason":"The sealed candidate specifies a consent-aware crossover using two comparable lesson segments, identical objectives and essential content, short bounded pauses, defined outcomes, accommodation checks, and immediate rollback."},"no_unresolved_safety_or_authority_stop":{"status":"YES","reason":"The candidate prohibits removal of required content or accommodations, coercive silence, hidden supports, continued pauses during distress, and consequential grading;
